Outline:Background: Understanding the long-term effects of environment on health behavior is important for the promotion of population-based physical activity.Purpose: The purpose of this study was to examine the relationship between perceived environment and active commuting among Japanese adults.Methods: Internet-based cross-sectional survey were conducted to 3,000 Japanese adults aged 30-59 years. Seven sociodemographic attributes (gender, age, marital status, employment status, living status, educational attainment and household income), type of commute and International Physical Activity Questionnaire Environment Module were assessed by self-administered questionnaire.Results: Of all respondents to the survey, 2,032 (mean age: 43.8±9.2, male: 62.5%) were employed. Those who use an active commute were 1,401 (68.9%). In both genders, high residential density (male: OR=2.28, female: OR=3.08), good access to shops (OR=2.03, 3.06), public transportation (OR=1.65, 3.78), recreational facilities (OR=1.31, 1.44), presence of sidewalks (OR=1.42, 1.77), crossroads (OR=1.87, 1.76), having a destination (OR=1.84, 2.34), and not having household vehicles (OR=15.13, 41.24) were associated with an active commute. The results indicated some gender differences. Among male, the presence of a bicycle lane and good aesthetics was positively associated with the active commute, while traffic safety was negatively associated. On the other hand, crime safety was associated with the active commute in female.Conclusion: The results indicate that perceived environment was associated with the active commute among Japanese adults.

Outline:[Purpose] The purpose of the present study was to clarify the factors associated with the persistence rate of home exercise (HE) to promote an improvement in treatment results post-operation. [Method] The participants were 17 people who had received single intervertebral laminotomy due to lumbar spinal disease. They were divided into two groups based on the persistence rate of HE in the investigation period (high group vs. low group). Self-efficacy, pre-onset physical activity level, and recognition of motor task were investigated. [Result] There were significant differences in pre-onset physical activity level, self-efficacy, and recognition of motor task between the two groups. [Conclusion] The factor that influenced the HE persistence rate of post-laminotomy patients was able to be determined, suggesting a plan for an HE guidance method to improve treatment results.

Outline:Purpose Although a foot care program for long-term care prevention has been launched in Japan, few studies have examined its effectiveness. The purpose of the present investigation was to examine the association of foot problems with fall experience and fear of falling among Japanese community-dwelling elderly people.
Methods The participants were 10,581 community-dwelling elderly people (75.2±5.6 years) and the study design was cross-sectional using a questionnaire. Self-reported tinea pedis, skin problems (inflammation, swelling, or discoloration), nail problems (thickening or deformities), impairment (in function or blood flow), regular foot care, and wearing of appropriate shoes were selected as parameters of foot problems and their care. Logistic regression analysis was conducted to examine whether these were related to fall experience (in thepast 1 year) and fear of falling adjusted for age, the Tokyo Metropolitan institute of gerontology index of competence, medical conditions, and lower limb functions.
Results Forty-six percents of males and 39.0% of females reported at least one foot problem. After adjusting for covariates, tinea pedis (male: adjusted odds ratio=1.37[95% confidence interval=1.15-1.63], female: 1.29[1.08-1.53]), skin problems (male: 1.66[1.32-2.10], female: 1.37[1.13-1.66]), nail problems (male: 1.72[1.45-2.05], female: 1.48[1.26-1.74]), and functional impairment (male: 2.42[1.91-3.05], female: 1.66[1.36-2.04]) were significantly associated with fall experience. Also, each problem was negatively associated with fear of falling (tinea pedis[male: 1.37[1.15-1.62], female: 1.25[1.07-1.47]], skin problems[male: 1.42[1.13-1.80], female: 1.62[1.34-2.00]], nail problems[male: 1.41[1.19-1.68], female: 1.46[1.25-1.70]], functional impairment [male: 2.05[1.61-2.60], female: 2.10[1.69-2.60]]). In addition, regular foot care (0.81[0.71-0.92]) was a significant correlate of fear of falling in females.
Conclusions These results imply that focusing on foot problems (i.e., tinea pedis, skin problems, nail problems, functional impairment) would be one of means for fall preventions. Well-designed prospective studies evaluating foot problems objectively are now needed to confirm the relationships indicated by this study.

Outline:Background Psychological, social, and environmental factors are important determinants for physical activity promotion. There are numerous studies of the direct effects of these factors on physical activity. However, only a few studies have been examined the direct and mediated effects of these factors on physical activity.Purpose The purpose of the present study was to examine the direct and indirect influences of psychological, social, and environmental factors on physical activity among Japanese adults.Methods An internet-based cross-sectional survey was conducted to 2,000 Japanese adults aged 20-79 years. Seven sociodemographic attributes (e. g., gender, age, and marital status), self-efficacy, pros and cons, social support for exercise and environmental variables (home fitness equipment, access to facilities, neighborhood safety, aesthetics, seeing others exercising) were assessed by a self-administered questionnaire. The physical activity was estimated from the Japanese version of the short form of the International Physical Activity Questionnaire. Data were analyzed using structural equation modeling by gender.Results The respondents' mean (SD) age was 43.6(13.0). Environmental factors had indirect effects on physical activity through self-efficacy, social support and pros and cons. On both gender, the strongest indirect effects was the path of environmental factors on physical activity through pros to self-efficacy. The total effects of environmental factors on physical activity were 0.06 of males and 0.04 of females.Conclusion The results indicate that environmental factors had indirect effects on physical activity through psychological and social factors among Japanese adults. These results could contribute to the development of physical activity promotion strategies in Japan.

Outline:[Purpose] The aim of the present study was to examine the relationship between walking behavior and psychological and environmental factors among patients with severe diabetes mellitus. [Methods] Twenty-two people (mean age 55.3 years) completed a questionnaire during educational hospitalization. Measured variables included the stage of change for walking behavior, self-efficacy for walking behavior, time spent in walking behavior, the Problem Areas In Diabetes survey (PAID), hospital anxiety and depression scale (HADS), and the International Physical Activity Questionnaire Environmental module (IPAQ-E). [Results] The total time spent in walking showed a significant positive correlation with self-efficacy for walking behavior, and a significant negative correlation with depression mood. [Conclusion] The results indicate that intervention approaches enhancing self-efficacy for walking behavior and reducing depressive mood might be effective for walking promotion among patients with severe diabetes mellitus.

Outline:Engaging in physical activity was proved to have positive effects on physical and mental health in children. Built environment is an important correlate of physical activity participation. School recess provides a daily opportunity for children to be active during school day. Therefore, the purpose of the present article was to review literatures regarding 1) physical activity during school recess, 2) the relationship between recess physical activity and school physical environment, 3) intervention for physical activity promotion during recess by changing school physical environment, and to explore trends of current researches and assignments of future research. A review was conducted and included studies published to May 31, 2011. Twenty-two studies were selected in 1) and showed boys often engaged in more physical activity than girls, but the results on differences in physical activity between ages were inconsistent. Six studies were selected in 2) and indicated recess physical activity was associated with playground environments such as equipments, marking, and surface situate. School environment intervention was observed to be a potential method for promoting physical activity in children by 8 studies in 3). Playground environment with marking, additional play equipments, and designated activity zones increased physical activity during recess. Most researches regarding recess physical activity was conducted in U.S., Australia, and Western countries, and confirmed the effectiveness of recess to promote physical activity. However, few studies on this topic were conducted in Japan. Further researches are needed to draw a conclusion about the possibility of recess to promote physical activity among Japanese children.

Outline:The purpose of this study was to explore patterns of lifestyle walking behavior among Japanese adults aged 30-49 and to identify their sociodemographic characteristics.A sample of 5,009 was collected from registrants of a social research company. The study was a cross-sectional survey using the Internet. Measured variables were walking behavior in five domains (commuting, working, shopping, exercising and other movement) and sociodemographic characteristics. Hierarchical cluster analysis was utilized to identify walking patterns.Four walking behavior clusters were identified: cluster 1 (N=1,089) walking while commuting, working and shopping; cluster 2 (N=381) walking while commuting; cluster 3 (N=1,257) walking for exercise; cluster 4 (N=1,161) walking while shopping. Cluster 1 had the highest proportion of walkers who met physical activity recommendations. Also it had a high proportion of women who were unmarried, employed, without children, or finished university or graduate school. Cluster 2 showed a high proportion of men who were married, with children, with high household income, or finished university or graduate school, and women who were married, employed, without children, with high household income, or finished university or graduate school. Cluster 3 had a high proportion of women aged 40-49. Cluster 4 showed a low proportion of men with high household income and a high proportion of women who were married, unemployed, or with children.This study indicated that walking behavior patterns in both genders was different depending on marital status, number of children, educational level and household income. In addition, the employment status of women had apparent effects on these patterns.

Outline:AIM: Previous reports have not demonstrated the oral health-related quality of life (OHRQOL) among patients with Crohn's disease (CD). Therefore, the present study examined the relationship between the OHRQOL, oral health behavior, and subjective oral symptoms among patients with CD. METHODS: Subjects were 60 CD patients (mean age: 37.0 ± 9.0 years; range: 20-56 years). The OHRQOL was assessed using the General Oral Health Assessment Index (GOHAI). The assessment of oral health behavior, i.e., brushing frequency, snack habit, frequency of observation of the oral health status and regular dental check-up visits, and subjective oral symptoms was based on responses in self-administered questionnaires. RESULTS: The GOHAI score by gender and age groups in CD patients was lower than that of nationalnorm data in every classification. There was no significant difference in the GOHAI score between CD subjects with good and those with poor oral health behavior, but there was a significant difference between those with and without subjective oral symptoms (p<0.001). CONCLUSIONS: These results suggest that patients with CD require the management of oral symptoms and improvement of their OHRQOL.

Outline:Objective: The purpose of this study was to clarify the process of shaping partnerships for developing and implementing a system of walking groups as a health promotion effort.Methods: We conducted a semi-structured interview with two public health nurses who were responsible for the IC-Walk program implemented by the Department of Health Promotion in M City and also performed document analysis regarding the program. Qualitative analysis was used to capture perspectives related to partnership formation processes by extracting codes, subcategories, and categories from interview transcripts and the documents.Results: Eighteen identified codes for shaping partnerships were grouped into nine subcategories ("mayors," "parties," "conferences," "groups," budget from sections beyond health," "subsidy," "private sector," "intersectoral collaboration within the government," and "intersectoral collaboration without the government"). Four categories were then abstracted: "political decision," "programs," "organization," and "budget". Finally, a structured model showed the relationships among the categories, taking into consideration the process of shaping partnerships.Conclusions: This study presented a structured model of the process of shaping partnerships for a municipal health promotion program. The model indicated that administrators' awareness and behavior contributed to the shaping of partnerships.

Outline:    Built environment is an important correlate of physical activity participation. Understanding the long-term effects of environment on health behavior is necessary for the promotion of population-based physical activity. However, most studies assessing the relationships between physical activity and environment have been conducted in the United States and Australia. The present study reviews Japanese researches on built environment and physical activity, and discusses the applicability of the built environment on promoting physical activity among Japanese adults. A review was conducted by searching the PubMed and Ichushi electronic database from inception to Sept 24, 2009. Eligible articles were identified as follows : 2 studies that developed the environment scale ; 10 studies that assessed the relationships with physical activity and built environment. There have been only a limited number of studies which were conducted with Japanese adults, thus more researches are needed to draw conclusions about the built environment associated with physical activity.

Outline:Purpose : The purpose of the present study was to explore the perception of strength training among older adults who engaged in strength training.
Methods : Semi-structured interviews were conducted with 15 participants aged 60-74 years who engaged in strength training in a sports facility. The questions of the interview included those regarding the mode of exercises they perceived as strength training, and perception about typical people engaged in strength training. Interviews were audio-taped and transcribed verbatim. The three interviewers reviewed the transcripts and categorized the perceptions.
Results : Nine categories of current perceptions of strength training were identified: structured exercises (n=15) , exercises for particular people (n=9) , exercises which those with positive outlook participated in (n=7) , easy exercises (n=6) , lifestyle activities (n=5) , exercises in which healthy people participated (n=5) exercises done in particular place (n=3) , vigorous-intensity exercises (n=2) , and unconcerned exercise (n=2) . Thirteen of participants mentioned the previous perceptions to strength training: unconcerned exercise (n=9) , exercises for particular people (n=7) , structured exercises (n=4) , vigorous-intensity exercises (n=3) , exercises done in particular place (n=1) , and others (n=4) .
Discussions : These results indicate that some older adults who engaged in strength training perceived strength training as an easy and lifestyle-based exercise, and that the perceptions might have been changed in the process of behavioral change for strength training.

Outline:Purpose : To understand the factors associated with the initiation and maintenance of strength training among older people, a qualitative approach would be useful. The purpose of the present study was to explore the initiation processes involved in strength training, and the facilitators and barriers to maintain strength training among people aged 60-74 years.
Methods : Semi-structured interviews were conducted with 15 members of a sports club. The interview consisted of questions related to initiation processes, facilitators, and barriers of strength training. Transcripts of the interviews were reviewed and categorizations were conducted.
Results : The initiation processes consisted of "coping with physical inactivity or health problems," "encouragement from others," "increase in leisure time," "feeling good program," "interests in physical activity," and "enjoyment of other sports," The common categories between facilitators and barriers were "physical factors," "psychological factors," "social factors," and "environmental factors." In addition, "daily life factors" and "other factors" were categorized as facilitators, and "uncontrollable factors" were categorized as barriers.
Discussion : These results indicate that 1) the initiation of strength training would be associated with interests in health problems and physical activity, increase of leisure time, encouragement from others, or presence of a good program, and that 2) the maintenance of strength training would be associated with environmental factors and daily life factors as well as physical and psychosocial factors.

Outline:    The present case study evaluated an environment-focused project for promoting walking, which included the development of walking courses (using public spaces, parks, roads) with stations for smart cards in the community and an interfaced internet-based self-monitoring system. The project was started in 2008 in Misato City of Saitama Prefecture. In this project, individuals can participate by paying a registration fee (500 yen) and obtaining their own cards. If registrants walk the course, holding their cards over a scanner at 3-4 stations, the smart card records their data (e.g. distance and time spent in walking) from one to the other station and transfers these to a self-monitoring system. As a result, registrants could check their data online. From June 2008 to November 2009, a total of 631 individuals (62% female) who obtained the information from newspaper, magazines, website, or some local events, registered for this project. From walking data collected automatically in the database through the self-monitoring system, it was found that 445 registrants (63% female) used this system at least once, and most of the registrants were 40 years old or more. This suggests that the project in this study might have been effective in promoting walking only among older people. Also, most of the registrants lived around the courses. In particular, the courses in the area surrounded by beautiful nature and residential areas were often used. To expand this idea to other age groups, new attempts, including a point supplying system based on the distance of walking are under development.

Outline:Objective:The present study examined physical activity(PA)levels and differences in PA by gender and grades during school recess periods. Method:PA levels of two hundred and thirty children(55% boys, 42%younger)from two elementary schools in Japan were measured with accelerometry for seven consecutive days. Time spent in sedentary, light PA, moderate PA, vigorous PA during break(25 minutes)and lunch recess(15 minutes), and total recess(40 minutes)was determined. Two-way analysis of variance was used to examine differences in PA variables by gender and grades. Results:Data of one hundred and eighty four children(52% boys, 56% younger)was available. Time spent in sedentary, light PA, moderate PA, and vigorous PA was 8.5±4.9, 12.9±3.8, 1.6±1.2, and 2.9±2.8 minutes during break, and 3.5±2.5, 9.5±2.2, 1.4±0.9, and 1.6±1.4 minutes during lunch recess, respectively. There were no significant interactions between gender and grades. Significant main effects of PA variables were found for gender and grades. Boys had fewer sedentary time(p=0.017)and higher vigorous PA time(p<0.001)than girls during total recess. Younger engaged in more sedentary(p=0.045)and less light(p=0.023)and moderate PA(p=0.006)than older at break. On the other hand, at lunch recess, younger had significantly longer light(p=0.015)and vigorous PA(p<0.001)and shorter sedentary time(p<0.001)than older. Conclusion:Overall, boys were less sedentary and engaged in PA at higher intensity levels than girls during school recess. Different pattern in PA was shown between break and lunch recess by grades.

Outline:Objective The objective of this study was to examine the relationship between perceived environment and achieving recommended level of walking, moderate to vigorous physical activity excluding walking or moderate to vigorous physical activity among Japanese adults.Methods Internet-based cross-sectional survey was conducted using the sample of 3,000 Japanese adults aged 30-59 years. Physical activity and neighbourhood environment were assessed by the short version of International Physical Activity Questionnaire (IPAQ) and IPAQ Environment Module. Participants were assigned to either "meeting recommendation" or "not meeting recommendation" according to criteria; ≥150 minutes per week of walking, moderate to vigorous intensity activity excluding walking or moderate to vigorous physical activity. Odds ratio of meeting physical activity recommendation was calculated in relation to environmental variables by gender, adjusted for sociodemographic attributes (gender, age, marital status, employment status, living status, educational attainment and household income). Results Convenient access to shops (male: OR=1.44, female: OR=1.73), public transportation (OR=1.75, 1.88), recreational facilities (OR=1.51, 1.37), good street connectivity (OR=1.32, 1.44), having destinations (OR=1.62, 1.44), and having household motor vehicles (OR=1.66, 1.85) were significantly related to meet the recommended level of walking. Access to recreational facilities (OR=1.33, 1.47), social environment (OR=1.48, 1.35) and aesthetics (OR=1.30, 1.39) were significantly related to meeting the recommended level of moderate to vigorous physical activity excluding walking. Convenient access to shops(OR=1.46, 1.36), public transportation (OR=1.60, 2.03), recreational facilities (OR=1.54, 1.41), having a destination (OR=1.54, 1.33), and good aesthetics (OR=1.41, 1.43) were significantly related to meet the recommended level of moderate to vigorous physical activity. Conclusion The moderate to vigorous physical activity excluding walking were associated with environment for exercising such as recreational facilities and social environment. The walking and moderate to vigorous physical activity including walking were associated with environment for lifestyle physical activity such as convenient access to shop and public transportation. Perceived environment influence was different depending on types of physical activities among Japanese adults.

Outline:    Most researches on sports spectators have concentrated on how to increase spectating frequencies and they have conducted surveys only on sports spectators. The potential spectator market was reported to be 39.3%, which is equivalent to the actual Japan' s spectators' market. Therefore, it is necessary to conduct research on potential spectators. In the Behavioral Science domain one of the most effective models is the Transtheoretical Model of behavior change (TTM) , which can be applied to various behaviors. The present study examined the application of the TTM to sports spectating behavior, especially in the case of several ball games held in a top sports league. In particular, questionnaires were administered to adults aged 20-69 to assess the reliability and validity of the stages of change for the sports spectating behavior scale. In study I, (reliability test) , data collected from 166 adults through the internet showed a good reliability among the 2-week test-retest [Kappa Index (κ) =.67] . Then, in study II, (validity test) , the relationship between the stages of behavioral changes of sports spectating and the degree of self-reported sports spectating behavior (the annual length of spectating time, intention of spectating) was investigated among adults in A city. The results revealed that sports spectating behavior significantly differentiated among the stages of change. Specifically, participants in the post-adoption stages (preparation, action, and maintenance) reported a significantly greater amount of annual sports spectating time compared to those in pre-adoption stages (pre-contemplation and contemplation) . Moreover, participants in pre-contemplation stages reported a significantly lower score in intention of spectating compared to those in other stages. The TTM, originally developed for various behaviors such as healthy and unhealthy ones, can be generalized for use in evaluating sports spectating behavior.

Outline:Objective: Environmental factors are related to physical activity among youth on a long-term. The purpose of the present study was to develop a neighborhood physical activity environment scale and to examine the relationship between neighborhood physical activity environment and out-side of school physical activity and school commuting among Japanese elementary students.Methods: Internet-based survey was administered to 1,074 Japanese guardians aged 20-59 years who had elementary school child. Sociodemographic attributes (gender and age of guardians, gender, age, hight and weight of children), neighborhood physical activity environment scale including 16 items and time of physical activity during out-side of school for leisure and walking to school commuting were assessed by the self-administered questionnaire.Results: Exploratory factor analyses identified 4 factors labeled "safety" with 5 items, "pleasing aesthetic" with 4 items, "crime safety" with 2 items and "uncomfortable aesthetic" with 2 items. Confirmatory factor analyses to examine the construct validity revealed acceptable fit indices (GFI = 0.969, AGFI = 0.949, RMSEA = 0.052, AIC = 288.360). The reliability of the subscale was found good internal consistency (r = 0.67-0.79) and moderately high inter-rater reliability (r = 0.55-0.68). Those who perceived good "safety", "pleasing aesthetic" and "uncomfortable aesthetic" environments were significantly more likely to spent of physical activity during out-side of school for leisure and school commuting.Conclusion: The valid and reliable neighborhood physical activity environment scale was developed and it is applicable to the assessment of neighborhood environmental perceptions relevant to physical activity in Japanese elementary school children.

Outline:Purpose: In a rapid developing Internet society, eHealth literacy becomes important to promote eHealth and aid in health care among individuals and groups. However, little is known about eHealth literacy in Japan. The present study reviewed the concept and issues of eHealth Literacy to promote eHealth effectively through recent trends of eHealth literacy.Methods: Medline, CINHAL, ERIC and "Igaku-chuo-zasshi" were searched for studies published in English and Japanese before September 30, 2011. "eHealth literacy", "e-Health literacy", "e- literacy", "eHEALS" and "Health literacy & Internet" were used as key words. A total of 161 publications were identified and 14 publications and 4 publications from reference lists met the inclusion criteria.Results: Twelve publications introduced the Lily model of eHealth literacy developed by Norman et al. in 2006 as follows: the ability to seek, find, understand, and appraise health information from electronic sources and apply the knowledge gained to addressing or solving a health problem. Furthermore, one study advocated the concept of eHealth literacy, three studies developed the scale of eHealth literacy and five studies examined the effect of eHelath literacy interventions and the eHealth literacy levels on people needing eHealth literacy.Conclusion: Lily model of eHealth literacy is the most prevalent concept. It is necessary to revise the concept of eHealth literacy to include the skills of use Web 2.0 tools (e.g. Social Networking Service) in eHealth literacy and conduct the studies using the valid scale of eHealth literacy.

Outline:Objectives Interviews were conducted with elderly people who had participated in the Care-Prevention Leadership Training Course (CPLTC), and had then established voluntary groups that practice care-prevention activities. This study examined the process and factors associated with the establishment of voluntary groups among subjects.
Methods The subjects were ten 62- to 76-year-old community-dwelling elderly in Tokyo who had taken the CPLTC. Data were obtained from 40- to 90-minute semi-structured interviews concerning the process of voluntary-group establishment. The data were then qualitatively analyzed using a modified grounded theory approach. Some of the concepts associated with the voluntary-group establishment were extracted, and organized into categories. These relationships were comparatively reviewed, and a figure for the results was constructed.
Results Subjects went through the following processes and feelings while establishing voluntary groups: "feelings that encourage participation in the local community," "opportunity for participation in the local community," "recognition of issues in the local community," "recognition of the importance of care prevention," "enhanced motivation for voluntary-group activities," and "recognition of requirements to establish a voluntary-group through its preparation." In addition, related factors were as follows; "past experience," "experience in the local community," "experience in CPLTC," "support in the local community," "support in CPLTC," "support in establishment of voluntary groups," and "feelings that promote or inhibit activities for the voluntary-group establishment." These processes were considered to be core concepts: "feelings and experiences that lead to participation in the local community," "deep understanding through experiences in the community and CPLTC," and "enhancement of motivation and skills for the activities through voluntary-group preparation."
Conclusion The results showed that the community-dwelling elderly experienced gradual changes in their feelings, awareness, and related factors concerning their establishment of voluntary groups. The data showed that three points of view were important in those changes: "participation in the local community," "recognition of issues in the local community," and "enhanced motivation and skills for community activities." With transition-related factors taken into account, it is possible to effectively support elderly who are establishing voluntary groups by promoting involvement in the local community, holding courses, and providing preparatory support for group establishment.

Outline:[Purpose] This study aimed to evaluate patients' recovery process of physical function and Health-Related Quality of Life (HRQOL) after Total Knee Arthroplasty (TKA). [Subjects] The subjects were 40 knee osteoarthritis patients in TKA rehabilitation. [Methods] The Timed-Up-and-Go test (TUG), the knee extensor strength, and one-leg standing (OLS) time with open eyes were measured. The Modified-WOMAC and the SF-36 were used for evaluation of HRQOL. [Results] All the scores, including the Modified-WOMAC pain score and the SF-36 scores of physical functioning, bodily pain, general health perceptions and social functioning at one month post-TKA and the Modified-WOMAC knee function score at three months post-TKA, were significantly improved. All the scores regarding physical function and HRQOL were significantly negatively correlated in terms of changes and initial values, except the OLS time with open eyes. [Conclusion] These results suggest that HRQOL improves within one month following TKA, and that physical function improves within three months after TKA.

Outline:Aim: The objective of the present study was to evaluate the long-term effectiveness of an exercise program in modifying the exercise behavior of the community-dwelling elderly subjects. Methods: This study was a single-blinded randomized controlled trial. The subjects included 52 males and 65 females 65 years of age or over who were randomly assigned to an exercise-intervention group or a health-education group. The stages of change in exercise behavior were evaluated before and one-year after the intervention period. The subjects' physical function (muscle strength, balance, walking speed) and self-efficacy in each domain of the physical function were measured during the intervention period. Results: There were no significant differences in the stages of change before the intervention between the two groups. Significant differences in the stages of change were observed in "relapse" of stages at two points in time between the two groups (p<.01). A logistic regression analysis showed that "progression" of stages was associated with improvements in the timed up and go test (AOR 2.7; 95% CI 1.3-5.8) and sit and reach (AOR 1.14; 95%CI 1.0-1.3), while "relapse" of stages was associated with the group allocation (AOR 4.6; 95%CI 1.1-18.8), self-efficacy in "Walking" (AOR 1.54; 95%CI 1.0-2.3) and "Stair climbing" (AOR 0.68; 95%CI 0.5-0.9) with respect to physical activity during the intervention period. Conclusions: The results suggest that exercise intervention in community-dwelling elderly subjects is effective in preventing "relapse" of exercise behavior over long periods.

Outline:Objectives According to the interim report "National Health Promotion in the 21st Century (Healthy Japan 21)", the Exercise and Physical Activity Guide for Health Promotion 2006 (EPAGH2006) is an important resource in the field of physical activity in Japan. A previous study (Higo & Nakamura, 2008) showed that although the awareness level of EPAGH2006 was lower than for other health promotion policies (e.g., Healthy Japan 21), the proportion of people who walked regularly was higher in the EPAGH2006 awareness group than in the no-awareness group. This result indicates that promotion of EPAGH2006 would contribute to increase in the number of physically active people. The purpose of the present study was to identify longitudinal change in awareness of EPAGH2006, and to examine the relationship with levels of physical activity.
Methods The subjects were 1,100 Japanese adults (mean [SD], 39.8 [10.1] years) recruited from among the registrants of a Japanese social research company. This longitudinal study was conducted using online questionnaires in surveys in November 2007 (T1) and December 2008 (T2). The awareness level of EPAGH2006 was assessed with 3 choices, i.e., good understanding, awareness and no-awareness. The International Physical Activity Questionnaire short Version (Craig et al., 2003; Murase et al., 2002) was used to estimate the amount of physical activity that the subjects engaged in. The Mann-Whitney test was utilized to assess inter-group differences in changes in the amount of physical activity between the understanding and no-awareness groups.
Results The proportion of those who fully understood EPAGH2006 was 1.4% at T1 and 2.2% at T2 and did not significantly increase. The physical activity level in the understanding group at T2 was significantly decreased compared with the no-awareness groups at both T1 and T2 (p=0.013).
Conclusion The lack of increase in the awareness level between the two time points suggests that dissemination of EPAGH2006 has not been effective. A more strategic approach would appear to be required. However, the results also did not indicate that the awareness level of EPAGH2006 had a positive influence on physical activity. Further studies, conducted when the awareness levels improve, may elucidate the relationship between the levels of EPAGH2006 awareness and physical activity.

Outline:Objectives With the rapid developing an internet society, ehealth literacy, defined as the ability to seek, find, understand, and appraise and apply the knowledge gained to addressing or solving a health problem, becomes important to promote and aid health care at the individual level. However, the eHealth Literacy Scale (eHEALS) was only a scale developed to assess the ehealth literacy. Thus, the present study was conducted to evaluated the validity and reliability of a Japanese version of the eHEALS (J-eHEALS), and examine the association of ehealth literacy with demographic attributes and characteristics on health information searching among Japanese adults.
Methods Data were analyzed for 3,000 Japanese adults (males: 50.0%, mean age: 39.6±10.9 years) who responded to an Internet-based cross-sectional survey. The J-eHEALS, 6 demographic attributes, resources for obtaining health information (health resources), and contents of health information obtained from internet (ehealth contents) were obtained with a questionnaire. Confirmatory factor analysis and correlation with the communicative and critical health literacy scale were utilized to assess construct validity and criterion validity. Cronbach alpha and correlation coefficients were computed for internal consistency and test-retest reliability. Also, differences in J-eHEALS scores with each demographic attribute were examined with ANOVA and the independent t-test. Finally, chi-square tests were used to determine differences in the proportions of ehealth literacy groups (high or low) classified with a median split within health resources and ehealth contents.
Results Principal components analysis produced a single factor solution and confirmatory factor analysis for the 8-items model demonstrated high indices (GFI=.988, CFI=.993, RMSEA=.056). A significant positive correlation was found between the J-eHEALS and communicative and critical health literacy scores. Cronbach alpha was 0.93 (P<.01), and test-retest reliability was r=0.63 (P<.01). The J-eHEALS scores were significantly higher in women, the 40-and 50-year age group, those with high income, and individuals with a high frequency of internet searching. Furthermore, the high ehealth literacy group used many health resources and obtained a greater variety of ehealth contents as compared with the low literacy group. The most frequent resource was the internet in the high group, and television/radio in the low group. However, these results could be subject to bias because of the non-representative nature of the Internet population.
Conclusion The results indicate the J-eHEALS to be a highly validated and reliable scale. The present study suggests that enhancement of ehealth literacy will be important to utilize the increasing amount of health information on the internet effectively and appropriately.

Outline:    School-based extracurricular sports activity (SBECSA) is a beneficial activity for positive youth development. However, there are some problems regarding the management of SBECSA, such as the lack of SBECSA teachers who can coach expertly and the great burden for SBECSA teachers. Although the number of external coaches has not been sufficient, recruiting external coaches into SBECSA has been focused on to help resolve these issues. For further effective recruitment of external coaches, approaching the community residents who have motivation to be external coaches is important. Nevertheless, the sociodemographics associated with the motivation still have not been explored. Therefore, the purpose of the present study was to clarify the sociodemographics of community residents who have motivation to become involved in SBECSA as external coaches (potential external coaches) . An Internet-based cross-sectional survey was conducted by a social survey company with 19506 registrants aged 20-69 years. Stratified random sampling was continued till 100 potential external coaches were collected for both genders and every age group. Coaching motivation as an external coach and six sociodemographics (gender, age, occupational status, marital status, teaching credential, and coaching credential) were obtained. As a statistical analysis, logistic regression analysis was performed. Overall, 19239 participants were included in the analysis and 5.9% of them had coaching motivation. Potential external coaches were significantly less likely to be females (OR = 0.42) , people in their 30s (OR = 0.63) , 40s (OR = 0.40) , 50s (OR = 0.30) , 60s (OR = 0.24) than males and people in their 20s. In addition, workers (OR = 1.49) , students (OR = 1.52) , married people (OR = 1.32) , those who have teaching credentials (OR = 1.60) and coaching credentials (OR = 8.13) were more likely to be external coaches. In conclusion, the present study clarified the sociodemographics of potential external coaches. It is suggested in recruiting external coaches into SBECSA, providing promotion strategies which take these sociodemographic factors into account would be effective.

Outline:Sedentary behavior, defined as participation in activities such as sitting and reclining during waking hours that do not increase energy expenditure substantially, has been gaining increased focus in physical activity research. In the last decade, sedentary behavior has emerged as a new risk factor for physical and mental health, independent of moderate to vigorous intensity physical activity. Especially, older adults spend most of their waking time in sedentary activities. Despite this high exposure, a broader base of evidence on sedentary behavior research in older adults has not yet been well reviewed. To inform future directions on sedentary behavior research among older adults, the present study provides the overview of the evidence from recently-published studies. This review includes evidence on the prevalence of objectively-measured and self-reported sedentary behaviors; the relationships with sedentary behavior (too much sitting) with multiple health outcomes; the effectiveness of interventions to reduce sedentary time and an overview of public health recommendations on reducing and breaking up sedentary time. Additional studies with high methodological quality are still needed to develop informed guidelines for addressing sedentary behavior in older adults.

Outline:  Use of external coaches for school-based extracurricular sports activities has been promoted because of the lack of teachers who can coach expertly and the large burden placed on teachers when coaching and managing such activities. However, it has been reported that securing external coaches through human resources is difficult. To promote the use of external coaches, previous studies have suggested some possible strategies: 1) clarifying the role and status of external coaches, and promoting cooperative coaching with external coaches and teachers; 2) interactive collection and provision of information about external coaches and schools, and improving recognition of the mediation system; 3) improving the way external coaches are recruited, and setting a suitable trial period; 4) moderating institutional limitations for coaching frequency and number of coaches; and 5) holding workshops for external coaches. However, these suggestions were made from only an individual viewpoint (i.e. that of teachers, external coaches, and potential external coaches), and did not consider organizational perspectives. In Japan, there are some organizations that help recruitment of external coaches for school-based extracurricular sports activities. It is necessary to consider the opinions of these organizations to develop more realistic and concrete promotion strategies. Therefore, the present study explored in detail the trials, problems, challenges, and strategies of organizations in order to promote the recruitment of external coaches for school-based extracurricular sports activities. Face to face semi-structured interviews were conducted involving 15 individuals in 11 organizations (2 national and 4 prefectural organizations, 3 schools, 1 university, and 1 company) supporting the recruitment of external coaches for school-based extracurricular sports activities. The interviews contained questions asking details of the recruitment system, problems, challenges and management strategies. All interviews were audio-recorded with agreement from the participants. The transcript data were integrated into 7 trials and their details, problems, challenges, and strategies were described. The results indicated that in order to promote the engagement of external coaches, a number of factors were important, including building human relationships between external coaches and teachers led by teachers that could share information, interactive collection and provision of information through mediator and cooperation with other organizations, collecting information about external coaches and interviewing them before formal acceptance, keeping the coaching non-compensatory, holding workshops and creating feedback to promote communication and learning of external coaches, and considering the continuity of the trial. Knowledge of the various problems, challenges, and strategies from an organizational perspective would contribute to improvement of recruitment strategy. The results of the present study could also provide information that is beneficial for other organizations wishing to conduct similar trials.

Outline:Background: In contemporary society, prolonged sitting has become pervasive in our lives across many settings, including transportation, the workplace, and the home. There is a rapidly accumulating evidence that large volumes of daily sedentary time (typically in the contexts of television viewing, computer use, workplace sitting, and time spent in automobiles) are adversely associated with cardio-metabolic risk biomarkers, type 2 diabetes, some types of cancer, and premature mortality. Importantly, these detrimental associations remain even after accounting for time spent in physical activity. To inform future directions on sedentary behavior research among adults, the present paper reviews the evidence from recently-published studies, applying the behavioral epidemiology framework.Contents: This review includes evidence on the relationships with sedentary behavior (too much sitting) with health risk indicators; self-report and device-based measurement of sedentary behaviors; the prevalence and trends for key sedentary behaviors; an ecological model and the environmental correlates of sedentary behavior; the effectiveness of interventions to reduce sedentary time; and, an overview of public health recommendations on reducing and breaking up sedentary time.Conclusions: Future directions for sedentary behavior research are as follows: population-based prospective studies using device-based measures to better understand the impact of sedentary time on health outcomes, prospective studies to clarify the multiple levels of determinants of prolonged sitting time in different life settings, further intervention trials to reduce and break up sedentary behaviors in domestic, workplace, and transportation environments, translational research (such as mass media campaigns) to spread messages about reducing sitting time in daily life, and experimental studies to determine underlying mechanisms and dose-response relationships.

Outline:Objective: The present study examined the prevalence and correlates of awareness about the role physical activity plays in colon cancer prevention among Japanese adults.Methods: Data were analyzed for 1,964 Japanese adults (aged 44.7 years) who responded to an internet-based cross-sectional survey. The survey was used to assess awareness of the role of physical activity in colon cancer prevention, knowledge of colon cancer, exposure to information about physical activity and cancer, a self-reported physical activity and sociodemographic variables (gender, age, marital status, education level, employment status, household income, and colon cancer history). A multivariate logistic regression analysis was used.Results: Overall, 47.5% of respondents were aware of the preventive role of physical activity on colon cancer. Respondents aged 60-69 (AOR, 95%CI: 0.59, 0.45-0.79) were significantly less likely to be aware than respondents aged 20-29 years, while those with college graduates or higher (1.32, 1.05-1.66) were more likely to be aware than those who had graduate junior high or high school. Moreover, exposure to information about cancer and physical activity (2.07, 1.71-2.51), and meeting physical activity recommendations (1.43, 1.12-1.84) were positively associated with the awareness.Conclusions: Awareness of the role of physical activity in colon cancer prevention was not sufficient. The finding suggests that strategies are needed for promoting awareness of the effect of physical activity in colon cancer prevention among Japanese adults, especially in consideration of age and education level.

Outline:The purpose of this cross-sectional study is to investigate the difference in physical activity among elderly living in different areas in Japan ("Bunkyo Ward in Tokyo" (Bunkyo) and "Fuchu City in Tokyo" (Fuchu) as urban areas, and "Oyama Town in Shizuoka" (Oyama) as a non-urban area). Participants were 1859 community-dwelling residents aged 65-74 years, randomly selected from the residential registry (response rate: 68.9%). A mail survey using self-administered questionnaires was conducted. Multivariate logistic regression analyses were used to calculate the adjusted odds ratios (ORs) and 95% confidence intervals (95% CI) of various types of physical activity (eg, walking (Walking), going out (Going-out), bicycling (Bicycling), exercise habits (Exercise)), according to residential areas (reference category: Fuchu), stratified by gender, adjusting for socio-demographic variables. There was a significant difference in Going-out (ORs = 0.61 (95% CI: 0.44-0.86) for men, 0.48 (0.33-0.69) for women)), and Bicycling (0.04 (0.03-0.07) for men, 0.04 (0.02-0.07) for women) in Oyama compared to Fuchu. Furthermore, for women, there was a significant difference in Walking (0.56 (0.38-0.81)) and Exercise (0.59 (0.41-0.85)) in Oyama compared to Fuchu. There was a significant difference in Bicycling and Going-out for men in Bunkyo compared to Fuchu, but there was not a significant difference in other items. Low physical activity levels were observed in the elderly in the non-urban area compared to urban areas. The association was stronger in women. Regional difference might need to be taken into account for an effective physical activity intervention.

Outline:There has been a growing interest in dog ownership and walking as a unique and potential resource to provide physical activity for many individuals in the community. The present study reviewed current trends regarding the studies on dog ownership, dog walking, and human health, and clarified the future direction of research on the topic. There is evidence to suggest that it is not dog ownership itself, but rather dog-walking that contributes to increased physical activity and the likelihood of meeting public health guidelines for physical activity. Also, a growing body of literature indicates that dogs appear to provide an important form of social support, motivation, and obligation that encourages dog owners to walk. Regarding the environmental and policy-related factors associated with dog walking, some literature showed that access to a dog-supportive park/area or living in a walkable neighborhood seems to positively affect dog owners walking with their dog. The evidence is still limited on interventions for promoting dog owners walking with their dog. With the high level of dog ownership in many industrialized countries, further evaluation of physical activity, including dog walking and use of an accelerometer, identification of factors related to dog owners' regular/irregular dog walking by means of a longitudinal study, and implementation of an intervention study related to the promotion of physical activity among dog owners with a focus on dog walking are needed.

Outline:     In competitive sports, the enhancing of physical abilities, technical skills, and psychological states is vital for excelling in competition. A team' s psychological wellbeing is often the deciding factor in team sport success. Nevertheless, few efficient strategies have been made for boosting teams' psychological states, particularly during matches. Therefore, the aim of this study was to investigate practitioners' perceptions of Enjin (forming a circle) strategies used to enhance a team' s psychological acuity during matches. In addition, motivations to initiate Enjin strategies, content, and changes observed after implementing these strategies were emphasized. The study was conducted following three steps. First, a women' s collegiate basketball team' s Enjin strategies were observed and recorded during an official match. Second, a team coach and four players were interviewed concerning these strategies, after viewing a recording of the match. The participants were requested to provide (1) motivations to implement Enjin strategies; (2) Enjin content; and (3) changes experienced after implementing Enjin strategies. Third, the study results were analyzed following the KJ method. The analysis revealed seven motivations, including "routine," "desire to enhance team cohesion," and "foul play." In addition, four types of Enjin content were identified, including "encouragement," "information on tactics," "apologizing," and "battle cries." Subsequently, eleven changes, including "enhanced team cohesion" , "shared perspectives among team members," and "improved excitement levels," were identified. It was inferred that Enjin strategies enhanced the teams' psychological states, based on these results. However, additional studies involving several teams, games, events, and genders are required to complement these results.

Outline: School-based extracurricular sports activities are beneficial for positive youth development. However, there is a shortage of appropriate in-school coaches, and therefore recruitment of external coaches has been considered as one solution to this. A previous study has reported four model strategies of organizational promotion to recruit external coaches. These four models included "compensational support", "staff introduction", "delivery of collegiate students", and "cooperation with company". In order to promote the further development and popularization of these organizational trials, user-side evaluation is necessary. Therefore, the purpose of the present study was to clarify the strengths and problems related to these four organizational promotion strategy models when recruiting external coaches for school-based extracurricular sports activities from the viewpoint of teachers. The participants were 12 teachers who worked in public junior high or high schools. All of them had experience of coaching school-based extracurricular sports activities. Face-to-face semi-structured interviews were conducted with the individual participants, and all interview data were transcribed. Then, similar meaning units were grouped into themes with respect to the four models, strengths and problems. As a result, many specific themes for each model emerged. For instance, with regard to "compensational support", monetary support was regarded as a strength, although the early application period was a problem. With regard to "staff introduction", adequacy for beginners was a strength, but lack of mediation organization was a problem. With regard to "delivery of collegiate students", regular coaching was seen as a strength, but worry over not choosing a delivered external coach was a problem. With regard to "cooperation with company", high coaching skill was a strength, but an expensive coaching fee was a problem. Additionally, comprehensive opinions about all the models were reported, such as lack of information about the system and the need for educational coaching. These similarities and differences in the results indicated the importance of mediation system design considering the regionality and situation of the school-based extracurricular sports activity. Effective publicity and re-examination of financial manager is also needed. In addition, mediation organization and teachers should arrange previous meetings with external coaches to understand their human qualities and educational attitude. Furthermore, it would be valuable to develop the quality of external coaches through previous training or workshops. Finally, changes in the application period for each mediation system are suggested.

Outline:     Outdoor education contributes to positive youth development. Existing outdoor education in Japan has been conducted only in an "episodic" manner with a "single activity" basis in "imitation nature", although regular and various activities in "grand nature" have been considered more valuable for the growth of children. Therefore, the purposes of the present study were to develop and practice an outdoor education program that performed a "plural number" of experiences with "multiple activities" in "genuine nature", and to clarify the availability of the program. For this purpose, the "Buddy Kids Adventure Challenge Program" was developed on the basis of 12 years of practice with the "Buddy Adventure Team (Non-Profit Organization)". An inventory survey was conducted for 49 participants in the Buddy Kids Adventure Challenge Program and 26 participants′ parents to evaluate the program in 2013. Free descriptive answers for the questions with respect to experiences in the program were descriptively analyzed and a model of the growth of the participants in the Buddy Kids Adventure Challenge Program was generated. As results, self-esteem was increased by developing competence. Additionally, outdoor activities in the program and flow experience were associated. Strong relationship between adverse circumstances and flow experience were also demonstrated. The growth model of the present study showed that desiring pleasure in "grand nature" could allow participants to confront adverse circumstances. These adverse circumstances give participants flow experience and confidence by helping them to overcome adverse circumstances. Finally, self-esteem was increased and growth of participants was enhanced.

Outline:Objective: The present study was conducted to examine the effects of providing equipment for use during school recess on elementary school children's physical activity.
Methods: In this cross-sectional study, 98 fifth-grade children (63 boys) from two elementary schools were assigned to an intervention group (n = 39) or a control group (n = 59). The intervention group received equipment such as volleyballs and oval balls. The children's physical activity was measured using accelerometry before and three months after receiving the equipment. Evaluated indicators were time spent engaging in sedentary, light, moderate, and vigorous physical activity during break, lunch recess, and the entire school day. Analysis of covariance—with sex, body mass index, and physical activity level prior to receipt of the equipment as covariates—was performed to examine the differences between two groups with respect to physical activity after receiving the equipment.
Results: During break, lunch recess, and the entire school day, data were collected from 23, 25, and 18 children in the intervention group. In the control group, it was done from 41, 42, and 37 children, respectively. During break and lunch recess, the intervention group was less likely to engage in sedentary behavior (p = 0.01, p < 0.01) and more likely to engage in light physical activity (p < 0.01, p < 0.01) than the control group. Regarding vigorous physical activity during break, the intervention group was less likely to engage in vigorous physical activity (p = 0.02). During the entire school day, the intervention group was more likely to engage in moderate physical activity (p = 0.03) than the control group.
Conclusion: The availability of equipment for use during recess was associated with high levels of physical activity.

Outline:Summary: There is increasing evidence that psychological factors (e.g., pain coping strategies) play an important role in older adults' adjustment to musculoskeletal pain. Therefore, interest in the use of cognitive behavioral therapy (e.g., pain coping skills training) to help older adults manage musculoskeletal pain is growing. In the present article, the first section reviewed the background on the necessary of cognitive behavioral therapy for managing musculoskeletal pain. The second section highlighted five techniques mainly used in pain coping skills training for musculoskeletal pain: cognitive restructuring, relaxation, distraction, pleasant activity scheduling, and activity-rest cycling. The third section introduced two printed materials newly developed for pain coping skills training and exercise therapy among older Japanese with knee pain. The final section of the present paper discussed important future directions for working within this research area. The present review revealed that it is important to apply the cognitive behavioral therapy (pain coping skills training) in management of musculoskeletal pain.

Outline:

Objectives The present study investigated articles on cancer prevention published in Japanese newspapers in 2011.

Methods A content analysis of news coverage on cancer primary prevention and screening was conducted. Articles which mentioned cancer risk, prevention, and screening were extracted. For all articles on prevention, the newspaper's name, month of publication, and information source were checked. Coding variables for articles on primary prevention included causes of human cancer, risk and/or prevention, and recommended screening criteria. Cancer screening articles were classified according to four coding variables: cancer screening site, subjects for screening, examination interval, and whether to promote the screening.

Results A total of 272 articles were identified and subsequently coded as either articles on primary prevention or screening. The number of articles on primary prevention was 208. The focus of these articles was mostly on food/nutrition (n=56), cancer-causing infection (n=40), and smoking (n=32). Alcohol drinking (n=12), exercise/physical activity (n=11), and obesity (n=10), which are also major lifestyle factors for cancer, were rarely mentioned. Moreover, cancer risk was more frequently mentioned than prevention. The recommended criteria for major lifestyle factors were mentioned in 13 articles. Screening was mentioned in 92 articles. Breast cancer screening was the most frequently mentioned (n=31). The screening of colon (n=18), cervical (n=18),stomach (n=15), and lung cancer (n=10), which are recommended by the cancer control act, were mentioned in less than 20 articles. Seven articles on screening indicated subjects and interval. Only 39 articles discussed cancer-screening behaviors.

Conclusions Articles on cancer prevention were found to be published in Japanese newspapers. However, the number of articles on both primary prevention and screening was not enough, and there were some disparities in the lifestyle factors and specific type of screening that were mentioned in these articles. Considering the influence of newspapers as a source of information on cancer prevention, it is necessary to encourage publishers to increase the number of published articles on cancer primary prevention and screening in Japanese newspapers.

Outline:    Recently, the carry-over of physical fitness or physical activity from childhood to adulthood has been actively discussed. However, the carry-over effect of participation in organized sports is not well understood, despite the fact that organized sports participation has a number of positive effects on physical, mental, and social aspects. Therefore, the purpose of the present study was to clarify the association of organized sports participation during school age with organized sports participation and sports volunteer participation in adulthood. The data was secondarily obtained from “nationwide questionnaire research for promotion of sports activities according to the life stage” conducted by the National Recreation Association of Japan. This research was conducted with 1,200 Japanese adults (612 males and 588 females) who were 20-39 years old. Path Analysis was conducted with respect to each sex. Regarding association of organized sports participation in school-age with organized sports participation in adulthood, participation in elementary school was related to that of junior high school, participation in junior high school was related to that of high school and adulthood, and participation in high school was related to that of adulthood in males. By contrast, in females, participation in elementary school was related to that of junior high and high school, participation in junior high school was related to that of high school and adulthood, and participation in high school was related to that of adulthood. With respect to association of organized sports participation in school-age with sports volunteer participation in adulthood, only organized sports participation in high school was affected in males, and only organized sports participation in junior high school was affected in females. There is a possibility that participation in organized youth sports has a carry-over effect for adult sports involvement. In order to promote organized sports participation and sports volunteer participation in adulthood, enhancing organized sports participation in school-age would be valuables.

Outline:    Considering the benefits of participating in school-based extracurricular sports activities (SBECSA), providing active SBECSA is important. However, heavy burden on teachers in coaching and management of SBECSA has been reported. Additionally, appropriate allowance and role allotment have not been discussed enough. It is necessary to understand the quality and quantity of task-related burdens in coaching and managing SBECSA to promote discussion. Therefore, the purpose of the study was to quantify the temporal, psychological, and economic burdens on teachers in coaching and management of SBECSA. The present study used a mixed-methods approach. Firstly, a semi-structured interview was conducted to clarify the contents of tasks about coaching and management of SBECSA. Participants were 12 teachers who work in junior high school or high school. All interview data was recorded and transcribed verbatim. Through the recording process, 26 contents of SBECSA tasks were grouped. Secondly, a self-completed questionnaire survey was conducted. 200 junior high schools and 200 high schools were recruited. Seventy-three schools agreed to cooperate in the study, and 361 SBECSA teachers answered the questionnaire. Question items were as follows: yearly hours taken for each of the 26 tasks, psychological burdens to do each of the 26 tasks, and yearly expenditure for coaching and management of SBECSA. As results, exact temporal burden for each of the 26 tasks was examined. On average, SBECSA teachers were spending approximately 1,400 hours a year for coaching and management. Regarding psychological burden, there were some tasks which were highly perceived although the temporal burdens were comparatively low. SBECSA teachers were payed approximately 136,000 yen a year to coach and manage SBECSA. In conclusion, SBECSA teachers assumed various tasks for management other than direct coaching. Contents of tasks would affect psychological burden as well as temporal length. Additionally, heavy individual payment for coaching and management of SBECSA was revealed. Increasing support for SBECSA coaching and management is necessary to decrease teachers’ burden and promote youth sports.

Outline:

The present study is a systematic review of the effectiveness of acceptance and mindfulness based interventions for enhancing athletes' performance. Studies were initially identified by literature searches in multiple international and domestic databases. Search terms used included "acceptance-based", "acceptance and commitment therapy", "mindfulness", "sport", "athlete", and "performance". Studies were then assessed for inclusion by examination of their title, abstract, and full text. On this basis, 11 studies were selected for inclusion in the present review. No studies conducted in Japan met the criteria. The studies reviewed encompassed the Mindfulness-Acceptance-Commitment approach (n=5), Mindful Sport Performance Enhancement (n=2), and alternative interventions (n=4). Most of the studies (n=8) found positive effects on sport performance. In 2 other studies, enhancement of sport performance was observed during a follow-up period. These findings suggest that acceptance and mindfulness based interventions appear to be effective for enhancing sport performance. Because none of the studies reviewed was conducted in Japan, research is needed on the effects of acceptance and mindfulness based interventions on the performance of Japanese athletes.

Outline:BACKGROUND:An understanding of the contributing factors to be considered when examining how individuals engage in physical activity is important for promoting population-based physical activity. The environment influences long-term effects on population-based health behaviors. Personal variables, such as self-efficacy and social support, can act as mediators of the predictive relationship between the environment and physical activity. The present study examines the direct and indirect effects of environmental, psychological, and social factors on walking, moderate-intensity activity excluding walking, and vigorous-intensity activity among Japanese adults.;METHODS:The participants included 1,928 Japanese adults aged 20-79 years. Seven sociodemographic attributes (e.g., gender, age, education level, employment status), psychological variables (self-efficacy, pros, and cons), social variables (social support), environmental variables (home fitness equipment, access to facilities, neighborhood safety, aesthetic sensibilities, and frequency of observing others exercising), and the International Physical Activity Questionnaire were assessed via an Internet-based survey. Structural equation modeling was conducted to determine associations between environmental, psychological, and social factors with physical activity.;RESULTS:Environmental factors could be seen to have indirect effects on physical activity through their influence on psychological and social variables such as self-efficacy, pros and cons, and social support. The strongest indirect effects could be observed by examining the consequences of environmental factors on physical activity through cons to self-efficacy. The total effects of environmental factors on physical activity were 0.02 on walking, 0.02 on moderate-intensity activity excluding walking, and 0.05 on vigorous-intensity activity.;CONCLUSIONS:The present study indicates that environmental factors had indirect effects on walking, moderate-intensity activity excluding walking and vigorous-intensity activity among Japanese adults, especially through the effects on these factors of self-efficacy, social support, and pros and cons. The findings of the present study imply that intervention strategies to promote more engagement in physical activity for population-based health promotion may be necessary.

Outline:PURPOSE:Although a foot care program for long-term care prevention has been launched in Japan, few studies have examined its effectiveness. The purpose of the present investigation was to examine the association of foot problems with fall experience and fear of falling among Japanese community-dwelling elderly people.;METHODS:The participants were 10,581 community-dwelling elderly people (75.2 +/- 5.6 years) and the study design was cross-sectional using a questionnaire. Self-reported tinea pedis, skin problems (inflammation, swelling, or discoloration), nail problems (thickening or deformities), impairment (in function or blood flow), regular foot care, and wearing of appropriate shoes were selected as parameters of foot problems and their care. Logistic regression analysis was conducted to examine whether these were related to fall experience (in the past 1 year) and fear of falling adjusted for age, the Tokyo Metropolitan institute of gerontology index of competence, medical conditions, and lower limb functions.;RESULTS:Forty-six percents of males and 39.0% of females reported at least one foot problem. After adjusting for covariates, tinea pedis (male: adjusted odds ratio = 1.37[95% confidence interval= 1.15-1.63], female: 1.29[1.08-1.53]), skin problems (male: 1.66[1.32-2.101, female: 1.37[1.13-1.66]), nail problems (male: 1.72[1.45-2.051, female: 1.48[1.26-1.74]), and functional impairment (male: 2.42[1.91-3.05], female: 1.66[1.36-2.04]) were significantly associated with fall experience. Also, each problem was negatively associated with fear of falling (tinea pedis[male: 1.37 [1.15-1.62], female: 1.25[1.07-1.47]], skin problems[male: 1.42[1.13-1.801, female: 1.62[1.34-2.00]], nail problems[male: 1.41[1.19-1.68], female: 1.46[1.25-1.70]], functional impairment [male: 2.05[1.61-2.60], female: 2.10[1.69-2.60]]). In addition, regular foot care (0.81[0.71-0.921) was a significant correlate of fear of falling in females.;CONCLUSIONS:These results imply that focusing on foot problems (i.e., tinea pedis, skin problems, nail problems, functional impairment) would be one of means for fall preventions. Well-designed prospective studies evaluating foot problems objectively are now needed to confirm the relationships indicated by this study.

Outline:OBJECTIVES:According to the interim report "National Health Promotion in the 21st Century (Healthy Japan 21)", the Exercise and Physical Activity Guide for Health Promotion 2006 (EPAGH2006) is an im-portant resource in the field of physical activity in Japan. A previous study (Higo & Nakamura, 2008) showed that although the awareness level of EPAGH2006 was lower than for other health pro-motion policies (e.g., Healthy Japan 21), the proportion of people who walked regularly was higher in the EPAGH2006 awareness group than in the no-awareness group. This result indicates that pro-motion of EPAGH2006 would contribute to increase in the number of physically active people. The purpose of the present study was to identify longitudinal change in awareness of EPAGH2006, and to examine the relationship with levels of physical activity.;METHODS:The subjects were 1,100 Japanese adults (mean [SD], 39.8 [10.1 years) recruited from among the registrants of a Japanese social research company. This longitudinal study was conducted using online questionnaires in surveys in November 2007 (T1) and December 2008 (T2). The awareness level of EPAGH2006 was assessed with 3 choices, i.e., good understanding, awareness and no-awareness. The International Physical Activity Questionnaire short Version (Craig et al., 2003; Murase et al., 2002) was used to estimate the amount of physical activity that the subjects engaged in. The Mann-Whitney test was utilized to assess inter-group differences in changes in the amount of physical activity between the understanding and no-awareness groups.;RESULTS:The proportion of those who fully understood EPAGH2006 was 1.4% at T1 and 2.2%0 at T2 and did not significantly increase. The physical activity level in the understanding group at T2 was significantly decreased compared with the no-awareness groups at both T1 and T2 (p=0.013).;CONCLUSION:The lack of increase in the awareness level between the two time points suggests that dissemination of EPAGH2006 has not been effective. A more strategic approach would appear to be required. However, the results also did not indicate that the awareness level of EPAGH2006 had a positive in-fluence on physical activity. Further studies, conducted when the awareness levels improve, may elucidate the relationship between the levels of EPAGH2006 awareness and physical activity.

Outline::Although it is crucial to examine the environmental correlates of physical activity (PA) for developing more effective interventions for overweight populations, limited studies have investigated differences in the environmental correlates on body mass index (BMI). The purpose of the present study was to examine the perceived environmental correlates of PA among normal-weight and overweight Japanese men. Data were analyzed for 1,420 men (aged 44.4 ± 8.3 years), who responded to an internet-based cross-sectional survey of answering the short version of the International Physical Activity Questionnaire and its Environment Module. Binary logistic regression analyses were utilized to examine the environmental factors associated with meeting the PA recommendation (150 minutes/week) between the normal-weight and overweight men. After adjusting for socio-demographic variables, common and different environmental correlates of PA were observed among normal-weight and overweight men. Furthermore, significant interactions regarding PA were observed between BMI status and two environmental correlates: access to public transportation (P = 0.03) and crime safety during the day (P = 0.01). The results indicated that BMI status is a potential moderator between perceived environmental factors and PA and suggested that different environmental intervention approaches should be developed for overweight populations.

Outline::The authors examined the relationship between strength-training behavior and perceived environment in older Japanese adults. An Internet-based survey was conducted of 293 adults age 68.2 ± 2.8 yr. The dependent variable was regular strength-training behavior. The IPAQ environment module, access to facilities for strength training, and home equipment for strength training were environmental factors. Logistic-regression analysis was employed. After demographic variables (gender, age, educational background, household income, body-mass index, self-rated health status, smoking habit, and residential area) were adjusted for, home equipment for strength training (OR = 2.14, 95% CI = 1.50-3.06), access to facilities for strength training (OR = 2.53, 95% CI = 1.32-4.85), and observing active people (OR = 2.20, 95% CI = 1.06-4.58) were positively correlated with regular strength-training behavior. In conclusion, environmental factors associated with strength-training behavior were access to facilities for strength training, having home equipment for strength training, and observing active people.

Outline:BACKGROUND:Although regular physical activity can facilitate healthy aging, improve functional capacity, and prevent chronic diseases in the elderly, many of the Japanese elderly are not sufficiently active. Thus, examining the determinants is an important prerequisite for designing effective programs. The present study investigated the demographic, behavioral, psychosocial, and environmental determinants of meeting the national pedometer-determined physical activity recommendations for the elderly Japanese.;METHOD:Data were analyzed for 137 community-dwelling elderly Japanese aged 70 to 89 years (47% male, mean age = 74.5 years), who completed a questionnaire and wore a pedometer. Demographic (gender, age, marital status), behavioral (BMI, smoking, alcohol consumption), psychosocial (self-efficacy, social support, health professional advice), and environmental (perceived neighborhood environment) variables were self-reported. Averaged daily steps were obtained using 1-year pedometer measurements. Based on the national physical activity recommendations in Japan (males: 6700 steps; females: 5900 steps), the participants were divided into two categories - sufficiently active and insufficiently active. An adjusted logistic regression model was utilized.;RESULTS:Totally, 47.4% of the participants (males: 51.5%; females: 43.8%) met the national recommendations. When adjusting for all other variables, a higher self-efficacy for exercise (AOR = 1.16; 95% CI: 1.04-1.28) and positive perception of the neighborhood environment (AOR = 1.43; 95% CI: 1.03-1.98) significantly influenced the meeting of the national recommendations.;CONCLUSIONS:The findings clarified the need to identify effective intervention strategies to promote physical activity and suggest that an intervention design that accounts for these determinants may more effectively promote physical activity among the elderly Japanese.

Outline:BACKGROUND:Although physical activity is associated with a lower risk of colon cancer, few studies have described the physical activity required for colon cancer prevention in various sociodemographic subgroups. The current study examined the prevalence and sociodemographic correlates of attaining the 2 recommended physical activity criteria for colon cancer prevention among Japanese adults.;METHODS:The sample included 5322 Japanese adults aged 20 to 79 years. Seven sociodemographic attributes (eg, gender, age, education level, employment status) and the International Physical Activity Questionnaire were assessed via an Internet-based survey. The odds of meeting each physical activity criterion by sociodemographic variables were calculated.;RESULTS:Overall, 23.8% of the study population met the criterion of ≥ 420 minutes of moderate-intensity activity, and 6.4% met the criterion of ≥ 210 minutes of vigorous activity. Being male, highly educated, employed, living with another person, being married and having a higher household income were significantly correlated with the attainment of recommendations.;CONCLUSIONS:Participants who met the 2 activity recommendations differed in gender, education level, employment status, marital status, living conditions, and household income. The findings of the current study imply that strategies to promote more intense physical activity in all demographic groups may be necessary.

Outline:OBJECTIVES:With the rapid developing an internet society, ehealth literacy, defined as the ability to seek, find, understand, and appraise and apply the knowledge gained to addressing or solving a health problem, becomes important to promote and aid health care at the individual level. However, the eHealth Literacy Scale (eHEALS) was only a scale developed to assess the ehealth literacy. Thus, the present study was conducted to evaluated the validity and reliability of a Japanese version of the eHEALS (J-eHEALS), and examine the association of ehealth literacy with demographic attributes and characteristics on health information searching among Japanese adults.;METHODS:Data were analyzed for 3,000 Japanese adults (males: 50.0%,mean age: 39.6 + 10.9 years) who responded to an Internet-based cross-sectional survey. The J-eHEALS, 6 demographic attributes, resources for obtaining health information (health resources), and contents of health information obtained from internet (ehealth contents) were obtained with a questionnaire. Confirmatory factor analysis and correlation with the communicative and critical health literacy scale were utilized to assess construct validity and criterion validity. Cronbach alpha and correlation coefficients were computed for internal consistency and test-retest reliability. Also, differences in J-eHEALS scores with each demographic attribute were examined with ANOVA and the independent t-test. Finally, chi-square tests were used to determine differences in the proportions of ehealth literacy groups (high or low) classified with a median split within health resources and ehealth contents.;RESULTS:Principal components analysis produced a single factor solution and confirmatory factor analysis for the 8-items model demonstrated high indices (GFI = .988, CFI = .993, RMSEA= .056). A significant positive correlation was found between the J-eHEALS and communicative and critical health literacy scores. Cronbach alpha was 0.93 (P < .01), and test-retest reliability was r = 0.63 (P < .01). The J-eHEALS scores were significantly higher in women, the 40-and 50-year age group, those with high income, and individuals with a high frequency of internet searching. Furthermore, the high ehealth literacy group used many health resources and obtained a greater variety of ehealth contents as compared with the low literacy group. The most frequent resource was the internet in the high group, and television/radio in the low group. However, these results could be subject to bias because of the non-representative nature of the Internet population.;CONCLUSION:The results indicate the J-eHEALS to be a highly validated and reliable scale. The present study suggests that enhancement of ehealth literacy will be important to utilize the increasing amount of health information on the internet effectively and appropriately.

Outline:BACKGROUND:Although both insufficient physical activity (PA) and high screen time (ST) are independent risk factors for obesity, how the combination of sufficient/insufficient PA and high/low ST could increase obesity risk among the adult population of Japan is not known. This study examined joint associations of PA and ST with overweight among Japanese adults.;METHODS:An Internet-based survey collected data on height, weight, self-reported time spent in PA and ST, and sociodemographic variables from 2832 adults. Respondents were categorized into sufficient PA/low ST, sufficient PA/high ST, insufficient PA/low ST, or insufficient PA/high ST categories as per public PA guidelines and the median of ST. Logistic regression analysis examined the odds ratios (OR) of being overweight (body mass index, ≥ 25 kg/m(2)) according to the categories of PA and ST.;RESULTS:In comparison with the sufficient PA/low ST category, participants in the insufficient PA/high ST category were significantly more likely overweight (OR, 1.48; 95% confidence interval [95%CI), 1.14, 1.93) after adjusting for sociodemographic variables. A significantly higher OR for overweight (including obesity) among insufficient PA/high ST category was also observed in men, but no significant association was found in women.;CONCLUSIONS:Both insufficient PA and prolonged ST contribute to overweight and obesity among Japanese adults. Public health initiatives addressing obesity in Japan need to consider both promoting PA and reducing ST, especially in men.

Outline:BACKGROUND:There are no previous data on factors at multiple levels associated with the stages of change for dog walking. The current study examined psychosocial and environmental correlates of the stages of change for dog walking among Japanese dog owners.;METHODS:Dog owners (N = 1940) completed a self-administered questionnaire that included items about demographics as well as psychosocial (dog attachment, dog obligation, normative belief, social norm, social support, self-efficacy) and environmental (access to areas, neighborhood safety, enjoyable scenery, frequently observing others dog walking, area where dogs are allowed to be off the lead) factors. MANOVA and discriminant functional analysis were used.;RESULTS:The distribution of the dog owners across the stages was as follows: precontemplation (14.7%), contemplation (7.6%), preparation (39.7%), action (2.8%), and maintenance (35.2%). Although differences among the stages were found for all factors in MANOVA, the pattern of distinction among stages differed depending on the factors. Dog obligation and self-efficacy were the best predictors of the stages of change for dog walking.;CONCLUSIONS:Although psychosocial and environmental correlates differed with the stages, psychosocial factors such as the sense of obligation and self-efficacy in dog walking seem to make relatively stronger contributions to distinctions among the stages.

Outline:BACKGROUND:It is still not known whether overweight men have different patterns and socio-demographic correlates of self-reported physical activity (PA) compared with normal-weight men. Thus, this study examined the perceived PA patterns and associated socio-demographic factors among normal-weight and overweight Japanese men.;METHODS:Data were analyzed for 1,420 men (aged 44.4 ± 8.3 years) who responded to an Internet-based cross-sectional survey relating to socio-demographic variables, BMI status, and a short version of the International Physical Activity Questionnaire. Mann-Whitney, chi-square, and binary logistic regression analyses were employed.;RESULTS:Normal-weight men were significantly more likely to attain 150 minutes per week of moderate-to-vigorous PA than overweight men (26.6% vs. 21.3%; p=0.035), whereas there were no significant proportional differences in total PA and walking between the two BMI subgroups. With PA, a significant interaction was observed between BMI status and household income (p=0.004 for total PA; p=0.02 for walking). In the subgroup analyses, having a lower household income (odds ratio, 0.63; 95% confidence interval, 0.41-0.96) was negatively associated with attaining 150 minutes of walking per week among normal-weight men. No significant associations between household income and attaining 150 minutes per week of total PA and walking were found among overweight men.;CONCLUSIONS:The results revealed that patterns and socio-demographic correlates of self-reported PA in overweight men are different from those in normal-weight men. This finding suggests the necessity of developing specific strategies for PA intervention among overweight men. Socio-demographic correlates of PA may be more important for normal-weight than overweight men.

Outline:BACKGROUND:Exploring the detailed pattern and correlates of dog walking is crucial to designing effective interventions to increase the proportion of dog walkers. The current study examined the prevalence and pattern of dog walking, the association between dog walking and health-related physical activity, and the correlates of dog walking among dog owners in Japan.;METHODS:Japanese dog owners' (n=930) responses to an Internet-based cross-sectional survey were analyzed. A self-reported measure of physical activity, dog walking characteristics, and sociodemographic and dog-specific variables were obtained. Analyses of covariance and multivariate logistic regressions were used.;RESULTS:Overall, 64.4% of the surveyed dog owners walked their dogs. On an average, they walked their dogs 214.1±189.5 minutes per week. The dog walkers were 3.47 times more likely to meet physical activity recommendations, were significantly less likely to be unmarried (OR=0.61), and had higher levels of attachment with their dogs (OR=2.32) than the nondog walkers.;CONCLUSION:The findings confirmed that dog walking significantly helps dog owners meet physical activity recommendations for health and revealed that dog-specific factors such as dog attachment might be stronger correlates of dog walking than sociodemographic factors.

A growing body of literature indicates that dog-walking contributes to increased physical activity. However, most of the previous studies have been conducted in Australia or the U.S. and have sampled from the general adult population.;PURPOSE:This study examined the association between dog ownership, dog-walking, and physical activity in older Japanese adults.;METHODS:Participants were community-dwelling residents aged 65-74 years who responded to a population-based cross-sectional survey (N=1926). Physical activity, dog ownership, dog-walking, and sociodemographic attributes were self-reported (collected in 2010; analyzed in 2011). ANCOVAs and multivariate logistic regressions were used.;RESULTS:Overall, 14.0% of older adults were dog owners, with 71% reporting that they walked their dog for an average of 308.5±300.7 minutes/week. Dog walkers reported more minutes/week of moderate-to-vigorous physical activity (M±SE: 241.7±27.0) and total physical activity (M±SE: 698.6±40.6) than both non-dog walkers (M±SE: 110.7±41.8; M±SE: 527.2±62.9) and non-dog owners (M±SE: 164.7±9.1; M±SE: 519.2±13.7), respectively (p<0.05). Dog walkers also walked more minutes per week (M±SE: 508.0±33.4) than non-dog owners (M±SE: 384.5±11.3; p<0.05). Dog walkers were more likely to be sufficiently active than both non-dog walkers and non-dog owners (p<0.001).;CONCLUSIONS:Use of dog-walking may be a potentially viable means of intervention for increasing walking and overall physical activity in older Japanese adults.

Outline:BACKGROUND:In rapidly developing Internet-user societies, eHealth literacy has become important in promoting wellness. Although previous studies have observed that poor health literacy is associated with less knowledge and screening practice of colorectal cancer (CRC), little is known about whether eHealth literacy is associated with these variables.;OBJECTIVE:The present study examined associations between eHealth literacy, knowledge of CRC, and CRC screening practices.;METHODS:Data were analyzed for 2970 Japanese adults (men, 49.9%; mean age±SD, 39.7±10.9 years) who responded to an Internet-based cross-sectional survey. Knowledge of the definition of CRC, its risk factors and screening practice, previous experience of CRC screening, score on the Japanese version of the eHEALS (J-eHEALS), sociodemographic attributes (sex, age, marital status, educational attainment, and household income level), and frequency of Internet usage were obtained. Sociodemographic attributes and frequency of Internet usage were used as control variables in the multiple regression and logistic regression models.;RESULTS:eHealth literacy was positively associated with CRC knowledge (β=.116, <.001), when the covariables of both eHealth literacy and CRC knowledge were used in the multiple regression model. Moreover, after controlling for sociodemographic factors, which were significantly associated with eHealth literacy and CRC screening practice, an increase of 1 point in the eHEALS score signified that participants were 1.03 times (95% CI=1.01-1.05) more likely to undergo CRC screening.;CONCLUSIONS:Internet users with high eHealth literacy are more likely to have knowledge and previous screening practice related to CRC compared to those with low eHealth literacy.

Outline:OBJECTIVES:Although physical activity reduces the risk of diseases such as cancer, diabetes and cardiovascular disease, a large proportion of the population is not sufficiently physically active. Therefore, the present study examined the environmental, social, and psychological correlates for meeting the 2 recommended physical activity criteria: ≥420 min per week of at least moderate-intensity activity (MPA criterion) and ≥210 min per week of vigorous activity (VPA criterion) for colon cancer prevention among Japanese adults.;DESIGN:Cross-sectional study.;METHODS:The sample included 2000 Japanese adults aged 20-79 years. An Internet-based survey was used to assess seven sociodemographic variables (e.g., education level, employment status), environmental variables (home fitness equipment, access to facilities, neighborhood safety, aesthetic sensibilities, and frequency of observing others exercising, residential area), social variables (social support), psychological variables (self-efficacy, perceived positive (pros) and negative (cons) aspects of exercise), and physical activity. The adjusted odds of meeting each physical activity criterion by these variables were calculated.;RESULTS:Overall, 22.3% of the study population met the criterion of MPA, and 7.3% met the criterion of VPA. Having high self-efficacy, fewer perceived cons, possessing home fitness equipment, reporting enjoyable scenery, and living in a rural area were significantly associated with meeting the recommended criteria.;CONCLUSIONS:Participants who met the 2 activity recommendations differed by self-efficacy, cons, possession of home fitness equipment, reporting of enjoyable scenery, and residential area. These findings imply that strategies to promote more intense physical activities specifically in terms of these variables may be necessary for colon cancer prevention.

Outline:BACKGROUND:Physical activity is beneficial for adolescent health. The physical activity patterns of Japanese adolescents are relatively unknown. Therefore, this study aimed to describe the current patterns of physical activity and to identify sex and grade differences among them.;METHODS:The participants comprised 714 Japanese adolescents aged 12 to 15 years old (boys N = 372, girls N = 342) from a public junior high school in Okayama, Japan. Physical activity at school, outside of school after hours, and during lunch recess as well as the total leisure time in a usual week was assessed with a 5-item questionnaire. To assess the differences in the physical activity patterns by sex and grade, independent t tests and analysis of variance (ANOVA) were conducted, respectively.;RESULTS:Boys spent significantly more time in physical activity both inside and outside of school settings than girls (p < .05). Higher grade students were significantly less active than lower grade students (p < .05). Furthermore, the physical activity patterns across the grades differed between settings (at school, outside of school during the after-school period, lunchtime recess, and at home).;CONCLUSION:To increase physical activity levels among Japanese adolescents, implementation of after-school programs or environmental modifications developed within the school setting could be effective strategies.

Outline:BACKGROUND:Concern over the health risks of sedentary behavior has highlighted the need to examine factors associated with screen-based (television/computer) sedentary behavior. The present study examined the association of screen-based sedentary behavior with body weight and sociodemographic attributes among Japanese adults.;METHODS:A population-based cross-sectional study enrolled 1034 Japanese adults aged 40 to 69 years who lived in 2 Japanese cities. Sociodemographic variables, height, weight, and time spent on screen-based sedentary behavior were collected by self-administered questionnaire. Differences in screen time in relation to body mass index and weight gain since age 20 years were assessed by the Mann-Whitney U test. Independent associations of each variable with screen time were examined by forced-entry logistic regression analyses.;RESULTS:Mean (SD) age and median (interquartile range) duration of screen time per week were 55.6 (8.4) years and 832.0 (368.8-1263.1) minutes, respectively, for men, and 55.3 (8.4) years and 852.6 (426.0-1307.5) minutes, respectively, for women. Screen time among participants with weight gain was longer than among those with a weight gain of less than 10 kg (P = 0.08). Unmarried and unemployed participants had longer screen times. Participants aged 40 to 49 years were less likely than older age groups to spend time on screen-based sedentary behavior during leisure hours.;CONCLUSIONS:The present findings imply that strategies are necessary to discourage screen-based sedentary behavior among all demographic groups, especially among adults who are elderly, unmarried, or unemployed.

Outline:OBJECTIVES:Interviews were conducted with elderly people who had participated in the Care-Prevention Leadership Training Course (CPLTC), and had then established voluntary groups that practice care-prevention activities. This study examined the process and factors associated with the establishment of voluntary groups among subjects.;METHODS:The subjects were ten 62- to 76-year-old community-dwelling elderly in Tokyo who had taken the CPLTC. Data were obtained from 40- to 90-minute semi-structured interviews concerning the process of voluntary-group establishment. The data were then qualitatively analyzed using a modified grounded theory approach. Some of the concepts associated with the voluntary-group establishment were extracted, and organized into categories. These relationships were comparatively reviewed, and a figure for the results was constructed.;RESULTS:Subjects went through the following processes and feelings while establishing voluntary groups: "feelings that encourage participation in the local community," "opportunity for participation in the local community," "recognition of issues in the local community," "recognition of the importance of care prevention," "enhanced motivation for voluntary-group activities," and "recognition of requirements to establish a voluntary-group through its preparation." In addition, related factors were as follows; "past experience," "experience in the local community," "experience in CPLTC," "support in the local community," "support in CPLTC," "support in establishment of voluntary groups," and "feelings that promote or inhibit activities for the voluntary-group establishment." These processes were considered to be core concepts: "feelings and experiences that lead to participation in the local community," "deep understanding through experiences in the community and CPLTC," and "enhancement of motivation and skills for the activities through voluntary-group preparation.";CONCLUSION:The results showed that the community-dwelling elderly experienced gradual changes in their feelings, awareness, and related factors concerning their establishment of voluntary groups. The data showed that three points of view were important in those changes: "participation in the local community," "recognition of issues in the local community," and "enhanced motivation and skills for community activities." With transition-related factors taken into account, it is possible to effectively support elderly who are establishing voluntary groups by promoting involvement in the local community, holding courses, and providing preparatory support for group establishment.

Outline::The promotion of strength training is now recognized as an important component of public health initiatives for older adults. To develop successful communication strategies to increase strength-training behavior among older adults, the identification of effective communication channels to reach older adults is necessary. This study aimed to identify the information sources about strength training that were associated with strength-training behaviors among Japanese older adults. The participants were 1144 adults (60-74 years old) randomly sampled from the registry of residential addresses. A cross-sectional questionnaire survey was conducted. The independent variables were sources of strength-training information (healthcare providers, friends, families, radio, television, newspapers, newsletters, posters, books, magazines, booklets, the Internet, lectures, other sources), and the dependent variable was regular strength-training behavior. Logistic regression analysis was used to identify potential relationships. After adjusting for demographic factors and all other information sources, strength-training information from healthcare providers, friends, books and the Internet were positively related to regular strength-training behavior. The findings of the present study contribute to a better understanding of strength-training behavior and the means of successful communication directed at increasing strength training among older adults. The results suggest that healthcare providers, friends, books and the Internet are effective methods of communication for increasing strength-training behaviors among older adults.

Outline:BACKGROUND:Although considerable evidence has demonstrated that physical activity is associated with breast cancer prevention, few studies have assessed the level of awareness of this association. Awareness is a key first step to successful of behavior change. Increasing awareness may contribute to promote physical activity and prevent breast cancer at the population level. The present study examined the prevalence and correlates of awareness about the role of physical activity in breast cancer prevention among Japanese women.;METHODS:1,000 Japanese women aged 20-69 years (mean age: 44.3 ± 13.4 years) who responded to an internet-based cross-sectional survey. Awareness of the role of physical activity in breast cancer prevention, knowledge of breast cancer (symptom, risk factor, screening), exposure to information about physical activity and cancer, a self-reported physical activity, and sociodemographic variables (age, marital status, having a child, education level, employment status, and household income) were obtained. Force-entry logistic regression analysis was used.;RESULTS:The prevalence of awareness was 31.5% (95% CI: 28.6-34.4). Factors significantly associated with awareness included sociodemographic variables, exposure to information, and knowledge of breast cancer. Being married (AOR, 95% CI: 1.75, 1.05-2.92) was positively related to awareness, while having children (0.65, 0.36-0.86) was negatively related. College graduates or those with higher levels of education (1.50, 1.01-2.22) were significantly more likely to be aware than those who had not graduated high school. Moreover, exposure to information (2.11, 1.51-2.95), and high knowledge of symptoms (2.43, 1.75-3.36) were positively associated with awareness. Finally, low knowledge of risk factors (0.30, 0.22-0.40) was negatively associated with awareness.;CONCLUSIONS:Japanese women through internet-based study were poorly aware of the role of physical activity in breast cancer prevention. Awareness was especially low among individuals with children and higher knowledge of risk factors whereas high in married women, those with higher educational level, exposure to information, and greater knowledge of symptoms. The findings suggest that strategies to increase the awareness about the preventive role of physical activity are needed for breast cancer prevention in consideration of subgroups with low awareness.

Outline::Differences in recess physical activity (PA) according to perceived school environment among elementary school children were examined. Participants were 103 children from two schools in Japan. PA was measured using accelerometry for seven consecutive days. Time spent in sedentary or PA (light, moderate, or vigorous) during their morning recess (25 min) and lunch recess (15 min) was determined. The School Physical Activity Environment Scale (three factors: equipment, facility, and safety) was used to investigate perceived school environment. Environmental factor scores were assigned to low or high groups for each factor by median. An analysis of covariance, with grade as the covariate, was conducted separately by gender to examine differences in PA between two groups. During lunch recess, boys in the high-equipment group spent significantly more time in moderate PA (high: 1.5; low: 0.8 min) whereas girls in this group spent less time in light PA (9.3, 11.0). Boys in the high-facility group spent significantly less time in sedentary (2.3, 3.9) and more time in vigorous PA (2.4, 1.4) during lunch recess, and girls spent more time in moderate (2.1, 1.2) and vigorous PA (1.9, 1.3) during morning recess. Differences were observed in recess PA according to school environment perceptions. The present study may be useful for further intervention studies for the promotion of PA during recess.

Outline:OBJECTIVE:Leisure-time sedentary behaviors (LTSBs) have been associated adversely with health outcomes. However, limited research has focused on different categories of LTSB. We aimed at identifying categories of LTSBs and examining their separate associations with indices of health among Japanese older adults.;METHODS:A postal survey collected data on self-reported health, psychological distress, body mass index, moderate-to-vigorous physical activity (MVPA), LTSBs (five behaviors) and socio-demographic characteristics from 1,580 Japanese older adults (67% response rate; 65-74 years) in 2010. Exploratory factor analysis was used to classify LTSBs. Odds ratios (ORs) were calculated for associations of LTSB categories with self-reported health, psychological distress, overweight, and lower MVPA. Data were analyzed in 2013.;RESULTS:Two categories of LTSB: passive sedentary time (consisting of TV time, listening or talking while sitting, and sitting around) and mentally-active sedentary time (consisting of computer-use and reading books or newspapers) were identified. Higher passive sedentary time was associated with a higher odds of being overweight (OR: 1.39, [95% CI: 1.08-1.80]), and lower MVPA (1.26, [1.02-1.54]). Higher mentally-active sedentary time was associated with lower odds of lower MVPA (0.70, [0.57-0.86]).;CONCLUSIONS:Two types of sedentary time-passive and mentally-active-may play different roles in older adults' well-being.

Outline:PURPOSE:Environmental initiatives to support walking are keys to noncommunicable disease prevention, but the relevant evidence comes mainly from cross-sectional studies. We examined neighborhood environmental attributes associated cross-sectionally with walking and those associated prospectively with walking maintenance.;METHODS:Data were from the Australian Diabetes, Obesity and Lifestyle study collected in 2004-2005 (baseline) and in 2011-2012 (follow-up). Participants who did not move residence during the study period (n = 2684, age range: 30-77 yr at baseline) were categorized as regular walkers (walked five times per week or more) or not at baseline. Regular walkers were divided into those who stopped and those who maintained regular walking at follow-up. Regression analyses examined relationships of regular walking and walking maintenance with perceived attributes of neighborhood destinations and pedestrian environments.;RESULTS:Regular walking at baseline was significantly associated with availability of shops (odds ratio [OR] = 1.13, 95% confidence interval [CI] = 1.04-1.22), many alternative routes (OR = 1.12, 95% CI = 1.01-1.23), park or nature reserve (OR = 1.13, 95% CI = 1.02-1.26), bicycle or walking tracks (OR = 1.08, 95% CI = 1.00-1.17), and feeling safe to walk (OR = 1.18, 95% CI = 1.01-1.38). Maintenance of regular walking was associated with the availability of multiple alternative routes (OR = 1.19, 95% CI = 1.03-1.38). Having many alternative routes and walking tracks was associated with walking maintenance among those who were not or had stopped working.;CONCLUSIONS:Neighborhood destinations (shops and parks) and pedestrian environments (alternative routes, walking trails, and safety from crime) were found to be associated with regular walking, but only pedestrian environment attributes were found to be related to the maintenance of regular walking. Further evidence from prospective studies is required to identify other neighborhood environmental attributes that might support walking maintenance.

Outline::This study aimed to determine the relation between the regression slope relating minute ventilation to carbon dioxide output (VE/VCO2 slope) and maximum phonation time (MPT), and the MPT required to attain a threshold value for VE/VCO2 slope of ≤ 34 in chronic heart failure (CHF) patients. This cross-sectional study enrolled 115 CHF patients (mean age, 54.5 years; men, 84.9%). VE/VCO2 slope was assessed during cardiopulmonary exercise testing (CPX). Thereafter, patients were divided into 2 groups according to exercise capacity: VE/VCO2 slope ≤ 34 (VE/VCO2 ≤ 34 group, n = 81) and VE/VCO2 slope > 34 (VE/VCO2 > 34 group, n = 34). For MPT measurements, all patients produced a sustained vowel/a:/ for as long as possible during respiratory effort from the seated position. All subjects showed significant negative correlation between VE/VCO2 slope and MPT (r = -0.51, P < 0.001). After adjustment for clinical characteristics, MPT was significantly higher in the VE/VCO2 ≤ 34 group vs VE/VCO2 > 34 group (21.4 ± 6.4 vs 17.4 ± 4.3 s, F = 7.4, P = 0.007). The appropriate MPT cut-off value for identifying a VE/VCO2 slope ≤ 34 was 18.12 seconds. An MPT value of 18.12 seconds may be a useful target value for identifying CHF patients with a VE/VCO2 slope ≤ 34 and for risk management in these patients.

Outline::Maximum gait speed and physical activity (PA) relate to mortality and morbidity, but little is known about gender-related differences in these factors in elderly hospitalized cardiac inpatients. This study aimed to determine differences in maximum gait speed and daily measured PA based on sex and the relationship between these measures in elderly cardiac inpatients.A consecutive 268 elderly Japanese cardiac inpatients (mean age, 73.3 years) were enrolled and divided by sex into female (n = 75, 28%) and male (n = 193, 72%) groups. Patient characteristics and maximum gait speed, average step count, and PA energy expenditure (PAEE) in kilocalorie per day for 2 days assessed by accelerometer were compared between groups.Gait speed correlated positively with in-hospital PA measured by average daily step count (r = 0.46, P < 0.001) and average daily PAEE (r = 0.47, P < 0.001) in all patients. After adjustment for left ventricular ejection fraction, step counts and PAEE were significantly lower in females than males (2651.35 ± 1889.92 vs 4037.33 ± 1866.81 steps, P < 0.001; 52.74 ± 51.98 vs 99.33 ± 51.40 kcal, P < 0.001), respectively.Maximum gait speed was slower and PA lower in elderly female versus male inpatients. Minimum gait speed and step count values in this study might be minimum target values for elderly male and female Japanese cardiac inpatients.

ISSN:1471-2458

Outline:BACKGROUND:Providing information about cancer prevention might increase awareness of prevention and promote preventive behaviours. A better understanding about the prevalence and preferences of obtaining information about cancer might help to identify targeted individuals and design effective strategies for promoting cancer-preventive behaviours. Thus, the present study examined the prevalence and correlates of obtaining information about cancer among Japanese adults, and described preferences including source and content.;METHODS:Data were analysed for 3,058 Japanese adults (mean age 45.0 ± 13.4 years) who responded to an Internet-based cross-sectional survey. The data included whether information about cancer had been obtained, sources, preference for content, sociodemographic variables, health status, and cancer histories. Force-entry logistic regression analysis was used.;RESULTS:Overall, 46.7% of respondents had obtained information about cancer. Gender, age, and education level were statistically significant correlates of doing so. Women were more likely to obtain information (OR = 1.97) as were older age groups (40-49: OR = 1.54, 50-59: OR = 2.27, 60-69: OR = 3.83), those with higher education (2 years college or equivalent degree: OR = 1.31, college graduate or higher: OR = 1.48) and those with having cancer histories (personal: OR = 3.52, family: OR = 1.57, friends/co-worker: OR = 2.09). The most prevalent source of information about cancer was mass media. Content of prevention is most needed among inconsistent contents with the frequently obtained contents.;CONCLUSIONS:Less than half of the respondents information about cancer. The finding suggests that better health communication strategies would be necessary to inform Japanese people about cancer. Understanding which subgroups were less likely to obtain information and preferences of information might be effective in promoting cancer prevention.

Outline:BACKGROUND:There has been a growing interest in environmental initiatives to reduce sedentary behaviour. A few existing studies on this topic are mostly cross-sectional, focused on the general adult population, and examining neighbourhood walkability. This study examined associations of perceived environmental attributes with change in TV viewing time over seven years among older Australian adults in the Australian Diabetes, Obesity and Lifestyle (AusDiab) study.;METHODS:The AusDiab study is a population-based study on diabetes and its risk factors in adults. We used the data on 1072 older adults (60+ years at baseline) collected in 2004-05 (baseline) and in 2011-12 (follow-up; 45. 4% men, mean age 67.5 years). Generalized linear modelling examined associations with 7 years change in TV viewing time of nine perceived neighbourhood-environment attributes relating to local shops, alternative routes, footpaths, parks, attractiveness, natural features, bicycle/walkway tracks, local traffic, and safety.;RESULTS:On average, participants increased their TV viewing time from 127 min/day to 137 min/day over the 7 years period. Adjusted for baseline TV viewing levels, TV viewing time at follow-up was 8% lower (95%CI: 0.85, 0.99) among those who did not perceive local traffic as a deterrent compared to those who perceived traffic as a deterrent. A trend for significant interaction between working status and the presence of a parks nearby indicated that, for those who were not working, those who reported having parks nearby had a marginal association with lower TV viewing time at follow-up than those who did not (p = 0.048).;CONCLUSIONS:Overall TV viewing time increased on average by 10 minutes/day over 7 years among older Australian adults. Local traffic that makes walking difficult or unpleasant may increase older adults' leisure-time sedentary behaviours such as TV viewing, possibly by deterring outdoor activities.

Outline:© 2015, International Society of Behavioral Medicine.Background: Associations between levels of sedentary behavior and depressive symptoms independently and in combination with different levels of physical activity remain unclear. Purpose: This study aimed to examine independent and combined associations of physical activity (PA) and sedentary behavior (SB) with depressive symptoms among Japanese adults. Method: An Internet-based survey collected data on depression levels (Center for Epidemiologic Studies Depression Scale), self-reported time spent in PA and SB (Japanese short version of the International Physical Activity Questionnaire), and sociodemographic variables from 2,914 adults in 2009. Binary logistic regression analyses were conducted to examine the odds ratios (ORs) for being depressed (depression scores ≥16) according to independent PA levels (none, insufficient, sufficient), SB levels (low, moderate, high), and nine combinations of PA and SB categories. Results: After adjusting for potential confounders, sufficient PA level was found to be related to lower risk of depressive symptoms independently (OR = 0.61), whereas no significant associations were observed between SB levels and depression. In the combined associations, adults in the sufficient PA/high SB (OR = 0.44), sufficient PA/moderate SB (OR = 0.56), and sufficient PA/low SB (OR = 0.57) categories were significantly less likely to have depressive symptoms in comparison with the no PA/high SB category. Conclusion: Meeting physical activity recommendations is associated with a lower risk of depressive symptoms, regardless of time spent in total sedentary behavior. These results suggest that promoting physical activity may be an effective strategy against depressive symptoms among Japanese adults.

Outline:© 2016 by the American College of Sports Medicine.Purpose Both moderate-to-vigorous physical activity (MVPA) and sedentary behavior can be associated with adult adiposity. Much of the relevant evidence is from cross-sectional studies or from prospective studies with relevant exposure measures at a single time point before weight gain or incident obesity. This study examined whether changes in MVPA and television (TV) viewing time are associated with subsequent changes in waist circumference, using data from three separate observation points in a large population-based prospective study of Australian adults. Methods Data were obtained from the Australian Diabetes, Obesity, and Lifestyle study collected in 1999-2000 (baseline), 2004-2005 (wave 2), and 2011-2012 (wave 3). The study sample consisted of adults age 25 to 74 yr at baseline who also attended site measurement at three time points (n = 3261). Multilevel linear regression analysis examined associations of initial 5-yr changes in MVPA and TV viewing time (from baseline to wave 2) with 12-yr change in waist circumference (from baseline to wave 3), adjusting for well-known confounders. Results As categorical predictors, increases in MVPA significantly attenuated increases in waist circumference (P for trend < 0.001). TV viewing time change was not significantly associated with changes in waist circumference (P for trend = 0.06). Combined categories of MVPA and TV viewing time changes were predictive of waist circumference increases; compared with those who increased MVPA and reduced TV viewing time, those who reduced MVPA and increased TV viewing time had a 2-cm greater increase in waist circumference (P = 0.001). Conclusion Decreasing MVPA emerged as a significant predictor of increases in waist circumference. Increasing TV viewing time was also influential, but its impact was much weaker than MVPA.

Outline:© 2015 Ishii et al.Background: Physical activity levels in childhood have decreased, making the promotion of children's physical activity an important issue. The present study examined gender and grade differences in objectively measured sedentary behavior, physical activity, and physical activity guideline attainment among Japanese children and adolescents. Methods: In total, 329 boys and 362 girls age 3-15 years completed the survey. School grade, gender, height, and weight were collected by questionnaires and physical activity objectively measured using an accelerometer (Lifecorder Suzuken Co.). Physical activity level (in MET) was classified as sedentary (<1.5), light (≥1.5 to <3), moderate (≥3 to <6), or vigorous (≥6). Continuous zero accelerometer counts for ≥20 min were censored and a valid accelerometry study required at least 3 days (2 weekdays and 1 weekend day) with > 600 min/day total wear time. Two-way analysis of covariance and logistic regression analyses, adjusted for weight status and accelerometer wear time, were used to examine gender and grade differences in physical activity variables and the likelihood of physical activity guideline attainment by gender and grade level. Results: Participants were sedentary 441.4 (SD, 140.1) min/day or 53.7 % of the average daily accelerometer wear time of 811.2 (118.7) min, engaged in light physical activity 307.1 (70.0) min or 38.4 % of wear time, moderate physical activity 34.6 (14.8) min (4.3 %), vigorous physical activity 28.3 (19.1) min (3.6 %), and took 12462.6 (4452.5) steps/day. Boys were more physically active and took more steps/day than girls. Students in higher grades were less active than those in lower grades. Boys were significantly more likely to meet physical activity guidelines than girls (OR: 2.07, 95 % CI: 1.45-2.96). Preschoolers (6.66, 4.01-11.06), lower-grade elementary school students (17.11, 8.80-33.27), and higher-grade elementary school students (7.49, 4.71-11.92) were more likely to meet guidelines than junior high school students. Conclusions: Boys and lower-grade students engaged in more physical activity and were more likely to attain guidelines than girls and higher-grade students. These findings highlight the need for effective and sustainable strategies to promote physical activity in Japanese school children.

Outline:© 2016, Springer International Publishing Switzerland.Background and aims: Little information exists on the relation between respiratory muscle strength such as maximum inspiratory muscle pressure (MIP) and sarcopenia in elderly cardiac patients. The present study aimed to determine the differences in MIP, and cutoff values for MIP according to sarcopenia in elderly cardiac patients. Methods: We enrolled 63 consecutive elderly male patients aged ≥65 years with cardiac disease in this cross-sectional study. Sarcopenia was defined based on the European Working Group on Sarcopenia in Older People algorithm, and, accordingly, the patients were divided into two groups: the sarcopenia group (n = 24) and non-sarcopenia group (n = 39). The prevalence of sarcopenia in cardiac patients and MIP in the patients with and without sarcopenia were assessed to determine cutoff values of MIP. Results: After adjustment for body mass index, the MIP in the sarcopenia group was significantly lower than that in the non-sarcopenia group (54.7 ± 36.8 cmH2O; 95 % CI 42.5–72.6 vs. 80.7 ± 34.7 cmH2O; 95 % CI 69.5–92.0; F = 4.89, p = 0.029). A receiver-operating characteristic curve analysis of patients with and without sarcopenia identified a cutoff value for MIP of 55.6 cmH2O, with a sensitivity of 0.76, 1-specificity of 0.37, and AUC of 0.70 (95 % CI 0.56–0.83; p = 0.01) in the study patients. Conclusion: Compared with elderly cardiac patients without sarcopenia, MIP in those with sarcopenia may be negatively affected. The MIP cutoff value reported here may be a useful minimum target value for identifying elderly male cardiac patients with sarcopenia.

Outline:© 2014 The Author.The promotion of strength training is now recognized as an important component of public health initiatives for older adults. To develop successful communication strategies to increase strength-training behavior among older adults, the identification of effective communication channels to reach older adults is necessary. This study aimed to identify the information sources about strength training that were associated with strength-training behaviors among Japanese older adults. The participants were 1144 adults (60-74 years old) randomly sampled from the registry of residential addresses. A cross-sectional questionnaire survey was conducted. The independent variables were sources of strength-training information (healthcare providers, friends, families, radio, television, newspapers, newsletters, posters, books, magazines, booklets, the Internet, lectures, other sources), and the dependent variable was regular strength-training behavior. Logistic regression analysis was used to identify potential relationships. After adjusting for demographic factors and all other information sources, strength-training information from healthcare providers, friends, books and the Internet were positively related to regular strength-training behavior. The findings of the present study contribute to a better understanding of strength-training behavior and the means of successful communication directed at increasing strength training among older adults. The results suggest that healthcare providers, friends, books and the Internet are effective methods of communication for increasing strength-training behaviors among older adults.

Outline:© 2016, Published with license by Taylor & Francis. © 2016 Rina Miyawaki, Ai Shibata, Kaori Ishii, and Koichiro Oka. Newspapers could provide effective and comprehensive information about cancer to the public. The present study conducted a content analysis of cancer-related articles in Japanese newspapers published in 2011. In total, 5,314 articles were identified and subsequently coded. Coding variables included cancer type, the cancer continuum, and topic of articles mentioning cancer. Approximately half mentioned at least one specific type of cancer, with the focus mostly on lung, leukemia, and breast. Stomach and colon cancers, which have the highest morbidity, were relatively underreported. The continuum received little attention, and was mentioned in only 11% of articles. Treatment was the most frequently mentioned part of the continuum, with prevention and screening mentioned only rarely. The most frequently mentioned topic was social issues. The findings suggest that cancer-related articles were found regularly throughout the year, meaning that they might be one of the most important sources of cancer information. However, they are affected by social issues and there were some imbalances in both cancer type and continuum. Considering the influence of newspapers, it would be helpful for providing more effective and accurate information to the public if Japanese newspapers increased mentions of specific types of common cancers and the cancer continuum, especially prevention.

Outline:© 2016 Elsevier Ireland LtdBackground There is little information on the association of sarcopenia with physical activity in elderly cardiac patients. This study determined differences in physical activity and cutoff values for physical activity according to the presence or absence of sarcopenia in elderly male cardiac patients. Methods and results Sixty-seven consecutive men aged ≥ 65 years with cardiac disease were enrolled. We defined sarcopenia using the European Working Group on Sarcopenia in Older People algorithm. Patients were divided into the sarcopenia group (n = 25) and the non-sarcopenia group (n = 42). In the patients with and without sarcopenia of physical activities were evaluated to determine cutoff values of physical activity. Results After adjusting for patient characteristics, both the average daily number of steps (3361.43 ± 793.23 vs. 5991.55 ± 583.57 steps, P = 0.021) and the average daily energy expenditure of physical activity (71.84 ± 22.19 vs. 154.57 ± 16.18 kcal, P = 0.009) were significantly lower in the sarcopenia versus non-sarcopenia group. Receiver-operating characteristic analysis identified a cutoff value for steps of physical activity of 3551.80 steps/day for 1 week, with a sensitivity of 0.73 and 1-specificity of 0.44 and a cutoff value for energy expenditure of physical activity of 85.17 kcal/day for 1 week, with a sensitivity of 0.73 and 1-specificity of 0.27. Conclusions Physical activity in the male cardiac patients with sarcopenia was significantly lower than that in those without sarcopenia. The cutoff values reported here may be useful values to aid in the identification of elderly male cardiac patients with sarcopenia.

Outline:© JPES.Problem Statement: Many youths participate in school-based extracurricular sports activities (SBECSA). These SBECSAs contribute to positive youth development. However, SBECSAs sometimes require the outsourcing of human resources. The major reason is difficulty to manage SBECSAs by employing teachers as the primary coaching resources. Using external coaches is an effective solution for reducing the workload on teachers, and it can contribute to improving teachers’ and students’ knowledge and skills. Because teacher involvement also appears to provide benefits for students, cooperative coaching between external coaches and teachers is essential. However, the lack of evidence regarding the benefits that cooperative coaching offers students may result in inadequate cooperation. Approach: In all, 23 students who participated in SBECSAs were recruited from three junior high schools and three high schools that employed external coaches. An open-ended, semi-structured interview was conducted with each student. The KJ method was used for qualitative analysis of the responses. Purpose: The purpose of this study is to determine how external coaches and teachers impact students’ experiences in SBECSAs, and how external coaches and teachers differ and/or have similar impacts. Results: In terms of benefits from external coaches, six categories and 31 subcategories were identified. The major categories included the following: expert coaching; support for SBECSA teacher; general coaching; human network; improved SBECSA atmosphere; and equipment supply. Benefits from teachers comprised six categories and 22 subcategories. The major categories identified were as follows: general coaching; management and office work; participation in SBECSA; human network; connection with school life; and improved SBECSA atmosphere. Conclusions: Students perceived overlapping and specific benefits from both groups, which indicated that cooperative coaching would be more desirable to students than having only external coaches or teacher instruct their SBECSAs.

Outline:Background: In the rapidly developing use of the Internet in society, eHealth literacy-having the skills to utilize health information on the Internet-has become an important prerequisite for promoting healthy behavior. However, little is known about whether eHealth literacy is associated with health behavior in a representative sample of adult Internet users. Objective: The aim of this study was to examine the association between eHealth literacy and general health behavior (cigarette smoking, physical exercise, alcohol consumption, sleeping hours, eating breakfast, eating between meals, and balanced nutrition) among adult Internet users in Japan. Methods: The participants were recruited among registrants of a Japanese Internet research service company and asked to answer a cross-sectional Internet-based survey in 2012. The potential respondents (N=10,178) were randomly and blindly invited via email from the registrants in accordance with the set sample size and other attributes. eHealth literacy was assessed using the Japanese version of the eHealth Literacy Scale. The self-reported health behaviors investigated included never smoking cigarettes, physical exercise, alcohol consumption, sleeping hours, eating breakfast, not eating between meals, and balanced nutrition. We obtained details of sociodemographic attributes (sex, age, marital status, educational attainment, and household income level) and frequency of conducting Internet searches. To determine the association of each health behavior with eHealth literacy, we performed a logistic regression analysis; we adjusted for sociodemographic attributes and frequency of Internet searching as well as for other health behaviors that were statistically significant with respect to eHealth literacy in univariate analyses. Results: We analyzed the data of 2115 adults (response rate: 24.04%, 2142/10,178; male: 49.74%, 1052/2115; age: Mean 39.7, SD 10.9 years) who responded to the survey. Logistic regression analysis showed that individuals with high eHealth literacy were significantly more likely to exhibit the good health behaviors of physical exercise (adjusted odds ratio [AOR] 1.377, 95% CI 1.131-1.678) and eating a balanced diet (AOR 1.572, 95% CI 1.274-1.940) than individuals with low eHealth literacy. Conclusions: We found that some health behaviors, including exercise and balanced nutrition, were independently associated with eHealth literacy among Japanese adult Internet users.

Outline:© 2016 Elsevier Inc. Street layout is consistently associated with adults' travel behaviors, however factors influencing this association are unclear. We examined associations of street layout with travel behaviors: walking for transport (WT) and car use; and, the extent to which these relationships may be accounted for by availability of local destinations. A 24-h travel diary was completed in 2009 by 16,345 adult participants of the South-East Queensland Household Travel Survey, Australia. Three travel-behavior outcomes were derived: any home-based WT; over 30 min of home-based WT; and, over 60 min of car use. For street layout, a space syntax measure of street integration was calculated for each Statistical Area 1 (SA1, the smallest geographic unit in Australia). An objective measure of availability of destinations – Walk Score – was also derived for each SA1. Logistic regression examined associations of street layout with travel behaviors. Mediation analyses examined to what extent availability of destinations explained the associations. Street integration was significantly associated with travel behaviors. Each one-decile increment in street integration was associated with an 18% (95%CI: 1.15, 1.21) higher odds of any home-based WT; a 10% (95%CI: 1.06, 1.15) higher odds of over 30 min of home-based WT; and a 5% (95%CI: 0.94, 0.96) lower odds of using a car over 60 min. Local destinations partially mediated the effects of street layout on travel behaviors. Well-connected street layout contributes to active travel partially through availability of more local destinations. Urban design strategies need to address street layout and destinations to promote active travel among residents.

Outline:© 2016 Human Kinetics, Inc.Background: This study examined associations of perceived and objectively measured neighborhood environmental attributes with leisure-Time sitting for transport among middle-To-older aged Japanese adults. Method: Data were collected using a postal survey of 998 adults aged 40 to 69 years. Generalized linear modeling with a gamma distribution and a log link was used to examine associations of perceived (International Physical Activity Questionnaire-Environmental module) and Geographic Information Systems (GIS)-derived built environment attributes with self-reported leisure-Time sitting for transport. Results: Mean leisure-Time sitting time for transport was 20.4 min/day. After adjusting for potential confounders, perceived higher residential density, GIS-measured higher population density, better access to destinations, better access to public transport, longer sidewalk length, and higher street connectivity, were associated significantly with lower sitting time for transport. Conclusion: Residents living in neighborhoods with attributes previously found to be associated with more walking tended to spend less time sitting for transport during leisure-Time. The health benefits of walkability-related attributes may accrue not only through increased physical activity, but also through less sedentary time.

Outline:© 2017 Japan Geriatrics Society Aim: Social participation provides health benefits for older adults. However, there is the need to identify whether higher social participation is associated with older adults being more physically active and less sedentary (sitting time). We examined the associations of social participation with physical activity, and sedentary time, in a population-based sample of older Japanese adults. Methods: A population-based, cross-sectional mail survey carried out in 2010 was used to collect data on social participation, physical activity, sedentary time and sociodemographic characteristics. Data were examined from 1146 community-dwelling, unemployed older adults (mean age 70.1 years, 43% men). Multivariate logistic regression analyses were used to calculate odds ratios (OR) for associations of social participation with physical activity and total sedentary time; and, for associations with passive and mentally-active sedentary (sitting) time. Results: For both men and women, those with higher social participation were more physically active (OR 2.10, 95% CI 1.44–3.06 among men; OR 1.93, 95% CI 1.39–2.68 among women). Total sedentary time had significant associations among men (OR 0.62, 95% CI 0.42–0.90), but not among women (OR 0.80, 95% CI 0.58–1.11). Social participation was associated with less passive sedentary time (OR 0.55, 95% CI 0.38–0.81 for men; OR 0.72, 95% CI 0.51–0.99 for women). Conclusions: Promoting social participation among older adults could contribute to increasing physical activity and reducing sedentary time, with potential benefits for chronic disease. Further research is required to elucidate the deleterious and beneficial roles of passive and mentally-active sedentary time for older adults. Geriatr Gerontol Int 2017; 17: 1921–1927.

Outline:© 2017 Elsevier Ltd We examined whether street layout —a key urban design element— is associated with walking and sedentary behaviors in the context of a non-Western country; and, whether such associations differ between an urban and a rural area. In 2011, 1076 middle-to-older aged adults living in an urban and a rural area of Japan reported their walking and sedentary (sitting) behaviors. Two objective measures of street layout (intersection density and street integration) were calculated. Participants exposed to more-connected street layouts were more likely to walk for commuting and for errands, to meet physical activity recommendations through walking for commuting, and less likely to drive. These relationships differed between the urban and the rural area. This shows that previous findings from Western countries on associations of street connectivity with travel behaviors may also be applicable to Japan.

Introduction: The most effective type of social participation against psychological distress in older adults is not well documented. The aim of this study was to examine whether different types of social participation are associated with changes in psychological distress level in older men and women in Japan. Methods: Two thousand seven hundred community-dwelling older adults (aged 65-74 years, 50% women) were randomly selected from the resident registry of three cities. Of these, participants who reported social participation and psychological distress level in the baseline survey in 2010 were followed up. Psychological distress was evaluated based on K6 scales at baseline and follow-up (in 2015). Social participation level was examined using question items from the National Health and Nutrition Survey in Japan. Exploratory factor analysis was used to derive the underlying factor structure. Multiple linear regression analysis was used to examine the association between social participation and changes in psychological distress level after adjusting for covariates stratified by both gender and age group or living arrangement. Results: Data from 825 community-dwelling older adults (45.3% women) were analyzed. Social participation was categorized into two types using factor analysis: community involvement (volunteer activities, community events, clubs for the elderly) and individual relationship (friendship, communication with family and friends, hobbies). During the 5-year follow-up, 29.5% of participants reported a deterioration in psychological distress. Higher community involvement was independently associated with lower risk of psychological distress for older women (β = 0.099, p = 0.047), whereas there were no associations with individual relationship for either gender. Furthermore, in older women living with others, higher community involvement was also associated with lower risk of psychological distress (β = 0.110, p = 0.048). Conclusion: Community involvement provides older women with mental health benefits regardless of individual relationship level. Promoting community involvement may be an effective strategy for healthy mental aging.

Outline:© 2017 The Author(s). Background: It is vital to reduce the proportion of sedentary behavior in children. Understanding the duration and behavioral context is needed. The present study examined school-grade and sex differences in domain-specific sedentary times and concurrence with screen-time guidelines among Japanese elementary school children. Methods: A total of 625 children (330 boys) were surveyed in 2010 and 2014. Using a questionnaire, data regarding participants' grade (first through third grades: lower grades; fourth through six grades: higher grades), sex, weight, and height were collected in addition to the time spent per day engaging in each specific sedentary behavior separately: (1) reading or listening to music, (2) TV or video viewing, (3) TV game use, (4) internet use excluding class, (5) homework, and (6) car travel. Two-way analysis of covariance and logistic regression analyses, adjusted for BMI and moderate to vigorous physical activity, were used to examine school-grade and sex differences in sedentary behaviors and the independent risk of exceeding recommended total daily screen time ( < 2 h). Results: On 625 children, mean minutes (SD) of sedentary behavior per week in (1) - (6) were 90.3 (123.4), 535.0 (356.6), 167.3 (222.1), 23.9 (70.9), 264.9 (185.3), and 33.4 (61.2) in weekdays and 42.1 (70.0), 323.9 (232.0), 123.0 (96.4), 15.8 (49.9), 74.4 (96.4), and 71.3 (84.9) in weekends, respectively. There were differences in the minutes of sedentary behavior between participants of 2010 and 2014; e.g., TV game use and homework in weekdays and weekdays and car travel in weekends. Boys spent more time in TV game use, and girls spent more time reading, listening to music, doing homework, and car travel. Higher-grade students spent more time reading or listening to music, using a computer, and doing homework. Higher-grade students were 2.09 times (95% CI: 1.32 - 3.30) in whole week, 2.08 times (95% CI: 1.45 - 3.00) in weekday, and 1.88 times (95% CI: 1.29 - 2.74) in weekend more likely to spend ≥2 h per day in domains (2) - (4) (screen-time) than lower-grade students. Conclusions: Time spent engaging in each domain-specific sedentary behavior differed according to sex and school grade. Higher-grade students were less likely to meet screen-time guidelines. These findings highlight the need for domain-focused strategies to decrease sedentary behavior in Japanese school-age children.

Outline:© 2017 The Author(s). Background: Men are generally believed to be more physically active than women when evaluated using current physical activity (PA) guidelines, which count only moderate-to-vigorous physical activity (MVPA) in bouts lasting at least 10 min. However, it remains unclear men are truly more physically active provided that all-intensity PA are evaluated. This population based cross-sectional study aimed to examine gender differences in patterns of objectively-assessed PA in older adults. Methods: One thousand two hundred ten community-dwelling Japanese older adults who were originally randomly selected from residential registry of three municipalities were asked to respond a questionnaire and wear an accelerometer (HJA-350IT, Omron Healthcare). The prevalence of achieving current PA guidelines, ≥150 min/week MVPA in bouts lasting at least 10 min, was calculated. Gender differences in volume of each-intensity activity (METs-hour) were assessed by analysis of covariance after adjustment for age and wear time. Results: Data from 450 (255 men, mean 74 years) participants who had valid accelerometer data were analyzed. Women were less likely to meet the guidelines (men: 31.0, women: 21.5%; p < 0.05). However, women accumulated more light-intensity PA (LPA) and short-bout (1-9 min) MVPA, and thus established higher total volume of PA (men: 22.0 METs-hour/day, women: 23.9 METs-hour/day) (p < 0.05). Conclusions: Older women were less active when evaluated against current PA guidelines, but more active by total PA. Considering accumulated evidence on health benefits of LPA and short-bout MVPA, our findings highlight the potential for the limitation of assessing PA using current PA guidelines.

Background Physical activity and physical performance relate to quality of life, mortality, and morbidity in elderly people. However, little is known about differences in physical performance related to low-intensity light physical activity (LLPA), high-intensity light physical activity (HLPA), and moderate-intensity physical activity (MPA) and how they are separated by sex in elderly populations. Aims This study aimed to determine differences in LLPA, HLPA, MPA, and physical performance, and associations between these measures in community-dwelling elderly men and women. Methods Physical activity and physical performance such as timed-up-and-go test, one-leg standing time, and maximum gait speed were measured in 181 community-dwelling elderly men (mean age, 75.1 - 5.3 years) and 109 women (mean age, 73.4 - 4.8 years) in 2013. Physical activity was classified as LLPA (1.6∼1.9 METs of physical activity), HLPA (2.0∼2.9 METs of physical activity), and MPA (over 3 METs of physical activity). The association between the values of these three intensities of physical activity in the participants was assessed by Pearson's correlation coefficients. Multiple linear regression analyses were used to assess the association of physical performance values with the three groups defined by accelerometer- measured physical activity intensity adjusted for sociographic, behavioral, and multiple diseases in the participants. Results MPA was beneficially associated with all physical performance indicators in the men (all P < 0.05) and women (all P < 0.05). Only HLPA showed significant associations with the timed-up-and-go test (P = 0.001) and maximum gait speed (P = 0.006) in women. Discussion These results may support the notion that not only HLPA in women but MPA in both sexes appears to improve physical performance in elderly populations. Conclusion The present study findings provide novel epidemiological evidence for the potential benefits of HLPA in women and also reinforce the potential benefits of MPA in both sexes, which is the mainstay of public health recommendations.

Outline:© 2017, The New York Academy of Medicine. Several studies have examined how the associations of built environment attributes with walking behaviors may be moderated by socioeconomic status (SES). Such understanding is important to address socioeconomic inequalities in health through urban design initiatives. However, to date, there is no study examining the moderation effects of SES in the relationships of environmental attributes and walking in non-Western countries. The current study aims to examine associations of environmental attributes with walking behaviors among Japanese adults, and to test whether these associations were moderated by area-level SES. Data on walking were collected from Japanese adults using a nationwide Internet survey (N = 4605). Built environment measures including population density, street density, distance to the nearest public open space, and distance to the nearest commercial destination were calculated using geographic information systems software. An index of neighborhood deprivation was used as an area-level indicator of SES. Logistic regression models adjusted for clustering and sociodemographic variables were used. It was found that more residents in high SES areas walked for commuting, for errands, and for exercise compared with those who lived in low SES areas. When the whole sample was examined, all environmental attributes were associated with walking behaviors (except for street density not being associated with walking for exercise). Associations of environmental attributes with walking behaviors were moderated by area-level SES only in walking for exercise. Walking for exercise was associated with higher population density, higher street density (marginally significant), and shorter distance to the nearest commercial destination only in high SES areas. Our findings showed that the associations of these environmental attributes and walking behaviors were largely consistent across different SES levels. Therefore, urban design interventions focusing on low SES areas may help to reduce socioeconomic disparities in walking.

This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. This study aims to compare the outputs of the waist-worn Active style Pro HJA-350IT (ASP; used in studies with Asian populations), the waist-worn ActiGragh™GT3X+ using the normal filter (GT3X+) and the thigh-worn activPAL3 (AP) in assessing adults’ sedentary behaviour (total sedentary time, number of breaks) under free-living conditions. Fifty healthy workers wore the three monitors simultaneously during their waking hours on two days, including a work day and a non-work day. Valid data were at least 10 hours of wearing time, and the differences between monitors on the sedentary outputs using the AP as criterion measurement were analyzed by ANOVA. The number of participants who had complete valid data for work day and non-work day was 47 and 44, respectively. Total sedentary time and breaks estimated by the AP were respectively 466.5 ± 146.8 min and 64.3 ± 24.9 times on the work day and 497.7 ± 138.3 min and 44.6 ± 15.4 times on the non-work day. In total sedentary time, the ASP estimated 29.7 min (95%CI = 7.9 to 51.5) significantly shorter than the AP on the work day but showed no significant difference against the AP on the non-work day. The GT3X+ estimated 80.1 min (54.6 to 105.6) and 52.3 (26.4 to 78.2) significantly longer than the AP on the work day and the non-work day, respectively. For the number of breaks from sedentary time, on both days, the ASP and the GT3X+ estimated significantly more than the AP: 14.1 to 15.8 times (6.3 to 22.5) for the ASP and 27.7 to 28.8 times (21.8 to 34.8) for the GT3X+. Compared to the AP as the criterion, the ASP can underestimate total sedentary time and the GT3X+ can overestimate it, and more so at the lower levels of sedentary time. For breaks from sedentary time, compared to the AP, both the GT3X+ the ASP can overestimate.

Sedentary time (ST) is an important risk factor for a variety of health outcomes in older adults. Consensus is needed on future research directions so that collaborative and timely efforts can be made globally to address this modifiable risk factor. In this review, we examined current literature to identify gaps and inform future research priorities on ST and healthy ageing. We reviewed three primary topics:(1) the validity/reliability of self-report measurement tools, (2) the consequences of prolonged ST on geriatric-relevant health outcomes (physical function, cognitive function, mental health, incontinence and quality of life) and(3) the effectiveness of interventions to reduce ST in older adults. METHODS: A trained librarian created a search strategy that was peer reviewed for completeness. RESULTS: Self-report assessment of the context and type of ST is important but the tools tend to underestimate total ST. There appears to be an association between ST and geriatric-relevant health outcomes, although there is insufficient longitudinal evidence to determine a dose-response relationship or a threshold for clinically relevant risk. The type of ST may also affect health; some cognitively engaging sedentary behaviours appear to benefit health, while time spent in more passive activities may be detrimental. Short-term feasibility studies of individual-level ST interventions have been conducted; however, few studies have appropriately assessed the impact of these interventions on geriatric-relevant health outcomes, nor have they addressed organisation or environment level changes. Research is specifically needed to inform evidence-based interventions that help maintain functional autonomy among older adults.This consensus statement has been endorsed by the following societies: Academy of Geriatric Physical Therapy, Exercise & Sports Science Australia, Canadian Centre for Activity and Aging, Society of Behavioral Medicine, and the National Centre for Sport and Exercise Medicine.

Outline:© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved. No commercial use is permitted unless otherwise expressly granted. Sedentary time is a modifiable determinant of poor health, and in older adults, reducing sedentary time may be an important first step in adopting and maintaining a more active lifestyle. The primary purpose of this consensus statement is to provide an integrated perspective on current knowledge and expert opinion pertaining to sedentary behaviour in older adults on the topics of measurement, associations with health outcomes, and interventions. A secondary yet equally important purpose is to suggest priorities for future research and knowledge translation based on gaps identified. A five-step Delphi consensus process was used. Experts in the area of sedentary behaviour and older adults (n=15) participated in three surveys, an in-person consensus meeting, and a validation process. The surveys specifically probed measurement, health outcomes, interventions, and research priorities. The meeting was informed by a literature review and conference symposium, and it was used to create statements on each of the areas addressed in this document. Knowledge users (n=3) also participated in the consensus meeting. Statements were then sent to the experts for validation. It was agreed that self-report tools need to be developed for understanding the context in which sedentary time is accumulated. For health outcomes, it was agreed that the focus of sedentary time research in older adults needs to include geriatric-relevant health outcomes, that there is insufficient evidence to quantify the dose-response relationship, that there is a lack of evidence on sedentary time from older adults in assisted facilities, and that evidence on the association between sedentary time and sleep is lacking. For interventions, research is needed to assess the impact that reducing sedentary time, or breaking up prolonged bouts of sedentary time has on geriatric-relevant health outcomes. Research priorities listed for each of these areas should be considered by researchers and funding agencies.This consensus statement has been endorsed by the following societies: Academy of Geriatric Physical Therapy, Exercise & Sports Science Australia, Canadian Centre for Activity and Aging, Society of Behavioral Medicine, and the National Centre for Sport and Exercise Medicine.

Outline:© 2018 The Author(s) Objective measures of environmental attributes have been used to understand how neighborhood environments relate to physical activity. However, this method relies on detailed spatial data, which are often not easily available. Walk Score® is a free, publicly available web-based tool that shows how walkable a given location is based on objectively-derived proximity to several types of local destinations and street connectivity. To date, several studies have tested the concurrent validity of Walk Score as a measure of neighborhood walkability in the USA and Canada. However, it is unknown whether Walk Score is a valid measure in other regions. The current study examined how Walk Score is correlated with objectively-derived attributes of neighborhood walkability, for residential addresses in Japan. Walk Scores were obtained for 1072 residential addresses in urban and rural areas in Japan. Five environmental attributes (residential density, intersection density, number of local destinations, sidewalk availability, and access to public transportation) were calculated using geographic information systems for each address. Pearson's correlation coefficients between Walk Score and these environmental attributes were calculated (conducted in May 2017). Significant positive correlations were observed between Walk Score and environmental attributes relevant to walking. Walk Score was most closely associated with intersection density (r = 0.82) and with the number of local destinations (r = 0.77). Walk Score appears to be a valid measure of neighborhood walkability in Japan. Walk Score will allow urban designers and public health practitioners to identify walkability of local areas without relying on detailed geographic data.

Outline:

Background: Good quality measures of Japanese adults' sedentary behaviors are needed to accurately assess correlates of specific sedentary behaviors. The present study assessed criterion validity of total sedentary behavior and test-retest reliability of six domain-specific sedentary behaviors.

Methods: We administered a questionnaire, based on previous studies, that measured domain-specific sedentary behaviors. To examine validity, agreement between self-reported time spent in sedentary behaviors from the questionnaire and objectively-measured sedentary time using accelerometers was compared among 392 adults (aged 40–64 years) in two Japanese cities. For reliability, a 2-week interval test-retest was administered to a convenience sample of 34 participants.

Results: The correlation between total self-reported and objectively measured sedentary time was significant (all P < 0.001) and fair-to-good for workdays (ρ = 0.57) and whole week (ρ = 0.49), but was low for non-workdays (ρ = 0.23). The difference between the two measures was significant for whole week (z = −2.25, P = 0.03) and non-workdays (z = −5.50, P < 0.001), but was not significant for workdays (z = −0.60, P = 0.55). There was a significant positive association between the difference in the two measures and the average of these two measures (workdays: r = 0.53; non-workdays: r = 0.45; and whole week: r = 0.54, all P < 0.001). There was fair-to-good test-retest reliability of total sedentary time for each domain (workdays: interclass correlation coefficient [ICC] = 0.77, non-workdays: ICC = 0.53, and whole week: ICC = 0.7; all P < 0.01).

Conclusions: The scale of domain-specific sedentary behaviors is reliable for estimating where and for what purpose Japanese adults spend their sedentary time, and total sedentary time is valid for workdays and the whole week.

うつ予防のための身体活動の促進および座位行動の改善に関する指針の作成

2013

Research Results Outline: 本研究の目的は、わが国の成人における客観的・主観的に評価した身体活動および座位行動と抑うつ症状との関連を検討し、効果的なうつ予防対策の指針作成に向け 本研究の目的は、わが国の成人における客観的・主観的に評価した身体活動および座位行動と抑うつ症状との関連を検討し、効果的なうつ予防対策の指針作成に向けて、より焦点を当てるべき身体活動・座位行動の介入場面や活動内容の目安等を明らかにすることであった。... 本研究の目的は、わが国の成人における客観的・主観的に評価した身体活動および座位行動と抑うつ症状との関連を検討し、効果的なうつ予防対策の指針作成に向けて、より焦点を当てるべき身体活動・座位行動の介入場面や活動内容の目安等を明らかにすることであった。 対象者は、住民基本台帳より無作為抽出した40~69歳の地域住民3,000名のうち、研究参加に同意し、各種調査・測定に協力した410名であった。身体活動・座位行動に関しては、加速度計(オムロンヘルスケアActive Style Pro HJA-350IT)および調査票(Global Physical Activity Questionnaire:GPAQ;Workforce Sitting Questionnaire改良版)により評価した。また、抑うつ症状の評価には、抑うつ状態自己評価尺度日本語版(Center for Epidemiologic Studies Depression Scale:CES-D)を用いた。さらに、個人的属性として、性、年齢、教育歴、世帯収入、婚姻状況、就業状況、同居の有無、喫煙状況、飲酒状況、現病歴、BMI(身長、体重より算出)についても調べた。これらのデータについて欠損等がなかった343名を最終的な分析対象者とした。多変量ロジスティック回帰分析により、客観的評価による中等度の強度以上の身体活動および座位行動、生活場面ごとの中等度の強度以上の身体活動・座位行動指標と抑うつ症状との関連について検討した。すべての統計処理には統計解析ソフトSTATA12.0を用いた。 客観的評価による総身体活動について、全ての予測される交絡要因および客観的評価による総座位時間を調整しても、中等度の強度以上の身体活動時間の長い群は、短い群と比較して、抑うつ症状と有意な負の関連が認められた。生活場面別の身体活動については、仕事中における中等度の強度以上の身体活動時間の長い群は、低い群と比較して、約2.1倍抑うつ症状を示す割合が高かった。一方で、余暇時間における中等度の強度以上の身体活動時間が長い群は短い群と比べて、抑うつ症状と有意な負の関連がみられた。 客観的評価による総座位行動に関して、全ての予測される交絡要因および客観的評価による総身体活動時間を調整した結果、総座位時間と抑うつ症状に有意な関連は認められなかった。生活場面別の座位行動では、仕事や移動中以外での座位でのPCやスマートフォン利用時間の長い群は、短い群と比較して、約2倍抑うつ症状を示す者の割合が高かった。その他の生活場面別座位行動指標と抑うつ症状には有意な関連はみられなかった。 今後、うつ予防対策の指針作成に向けては、中等度の強度以上の総身体活動に加えて、仕事および余暇場面における中等度の強度以上の身体活動に着目すべきである。一方、座位行動に関しては、余暇でのPCやスマートフォン利用に伴う座位時間(移動中や仕事中を除く)を減らす取り組みが重要であることが分かった。

Two street layout measures (intersection density andstreet integration) were objectively calculated. Participants living in areas with more connected streetlayout weremore likely to walk for commuting and for errands, and less likely to drive. These relationshipsdiffered urban and rural areas. Our study confirms that previous findings from Westerncountries, i.e., the association of street connectivity with travel behaviors,are also applicable to Japan.

Research Results Outline:本研究の目的は、虚弱高齢者を対象に、自宅でも実施可能な抗重力筋を鍛えるための筋力向上トレーニングと、目標設定やセルフモニタリングなどの行動変容支援を組本研究の目的は、虚弱高齢者を対象に、自宅でも実施可能な抗重力筋を鍛えるための筋力向上トレーニングと、目標設定やセルフモニタリングなどの行動変容支援を組み合わせたプログラムを開発・実施し、その効果を身体的側面、心理的側面、行動的側面および転倒関連の側...本研究の目的は、虚弱高齢者を対象に、自宅でも実施可能な抗重力筋を鍛えるための筋力向上トレーニングと、目標設定やセルフモニタリングなどの行動変容支援を組み合わせたプログラムを開発・実施し、その効果を身体的側面、心理的側面、行動的側面および転倒関連の側面から検討することであった。介護予防健診を受診し、老年症候群のリスクを保有する65歳以上の虚弱高齢者で、プログラムへの参加に同意した35名を、性、年齢、老年症候群リスクを調整しながら、自重負荷筋力トレーニング群(筋トレ群:18名)、介護予防教育講座群(講座群:17名)にランダムに割り付けた。両介入プログラムとも、週1回、1回90分のセッションを12回(初回および最終回は効果測定)実施した。その結果、身体的側面では握力、椅子立ち座りが筋トレ群で、移動能力(TUG、通常および最大歩行速度)は両群ともにプログラム終了後に有意な改善が認められた。心理的側面では、両群ともにSF-36日本語版の8つの下位尺度のうち、心の健康を除く全ての項目(身体機能、役割機能-身体、身体の痛み、全体的健康感、活力、社会生活機能、役割機能-精神)が有意に改善した。行動的側面は、自己報告による一日平均歩行時間について、筋トレ群で有意な改善が認められた。転倒関連指標は、両群ともにすべての指標において有意な改善はみられなかった。以上のことから、本研究で実施した筋力向上トレーニングプログラムは、短期的ではあるが身体的側面、心理的、行動的側面に効果をもたらしたと考えられる。一方、プログラム開始から1年後まで追跡調査を行った結果、各側面において有意に改善していた多くの指標において、効果の維持が認められなかった。これらの結果から、長期的な効果の維持をもたらすような支援、特に運動習慣の定着をさらに促すような働きかけを介入プログラムに積極的に導入していくことの必要性が示唆された。
