Evidence about the impacts of the physical activity environment on adults' weight in the context of Asian countries is scarce. Likewise, no study exists in Asia examining whether Walk Score a free online walkability tool is related to obesity. This study aimed to examine associations between multiple physical activity environment measures and Walk Score ratings with Japanese adults' body mass index (BMI). Data from 1073 adults in the Healthy Built Environment in Japan study were used. In 2011, participants reported their height and weight. Environmental attributes, including population density, intersection density, density of physical activity facilities, access to public transportation, and availability of sidewalks, were calculated using Geographic Information Systems. Walk Scores ratings were obtained from the website. Multiple linear regression analysis was conducted to examine the association between each environmental attribute and BMI. Adjusting for covariates, all physical activity environmental attributes were negatively associated with BMI. Similarly, an increase of one standard deviation of Walk Score was associated with a 0.29 (95% confidence interval (CI) of-0.49--0.09) decrease in BMI. An activity-friendly built environment was associated with lower adults' BMI in Japan. Investing in healthy community design may positively impact weight status in non-Western contexts.

Background Little is known about differences in the risk of poor nutritional status as assessed by the Geriatric Nutritional Risk Index (GNRI) in relation to physical performance in elderly female cardiac inpatients. The present study aimed to determine both differences in physical performance based on the GNRI and physical performance cut-off values according to the GNRI in elderly female cardiac inpatients.Methods We enrolled 105 consecutive female Japanese inpatients aged a parts per thousand yen65 years (mean age, 74.6 years) with cardiac disease in this cross-sectional study. We divided the patients into two groups according to GNRI: high-GNRI group (a parts per thousand yen92 points) (n = 71) and low-GNRI group ( 92 points) (n = 34). Handgrip strength (HG), knee extensor muscle strength (KEMS), gait speed (GS), and one-leg standing time (OLST) were assessed as indices of hospital physical performance and compared between the two groups to determine cut-off values of physical performance.Results After adjustment for age and left ventricular ejection fraction, HG, KEMS, GS, and OLST were significantly lower in the low-GNRI versus high-GNRI group. Cut-off values by ROC curve analysis were 16.2 kgf (AUC = 0.66; p 0.001) for HG, 34.3 % of body weight (AUC = 0.62; p = 0.04) for KEMS, 1.24 m/s (AUC = 0.72; p 0.01) for GS, and 8.28 s (AUC = 0.62; p = 0.04) for OLST.Conclusions The risk of poor nutrition, as indicated by a low GNRI, might be a predictor of lower physical performance. Cut-off values determined in this study might be minimum target goals for physical performance that can be attained by elderly female cardiac inpatients.

Our study examined the associations between neighborhood walkability, frailty, and the incidence of long-term care insurance (LTCI) service needs using a prospective cohort survey in a suburban town in Japan. The final sample for analyses comprised 2867 community-dwelling older adults (mean age: 73.0 years). Neighborhood walkability was measured using the Walk Score(R). A total of 387 participants (13.5%) exhibited frailty. The odds of frailty, adjusted for the covariates (sex, age, educational status, marital status, residential status, employment status, subjective economic status) among participants who lived in somewhat walkable/very walkable areas, was 0.750 (95% Confidence Interval, CI: 0.597-0.943) versus those who lived in car-dependent areas. During the 23-month follow-up, 102 participants needed LTCI services (19.0 per 1000 person-years), 41 of whom (21.0 per 1000 person-years) lived in car-dependent areas, and 61 of whom (17.9 per 1000 person-years) lived in somewhat walkable/very walkable areas. As compared with participants who lived in car-dependent areas, the incidence of LTCI service needs was not significantly lower than that of those who lived in somewhat walkable/very walkable areas. Walk Score(R) can provide the critical information for the strategies to improve walkability and prevent older adults' frailty in less walkable areas, contributing to achieving the United Nation's Sustainable Development Goals (SDGs).

Exercise maintenance after supervised cardiac rehabilitation is important in maintaining both physical activity and physiological factors, such as peak VO2 and muscle strength (MS), associated with reduced mortality. However, there is no evidence of the effects of unsupervised exercise training and MS training on physical activity and physiological factors after supervised cardiac rehabilitation of Japanese cardiac patients. We conducted a randomized, controlled trial to evaluate the effect of unsupervised exercise training on physical activity and selected physiological factors after supervised cardiac rehabilitation. Eighteen myocardial infarction (MI) patients (16 men, 2 women; mean age 66.3 years) were recruited following completion of a supervised recovery-phase cardiac rehabilitation program. Patients were randomly assigned to a MS training (n=10) or control group (n=8). Baseline measurements of physical activity, peak VO2, and MS were performed at the end of supervised recovery-phase cardiac rehabilitation (6 months after the onset of MI: T1). Six months later, after going through an unsupervised exercise program (12 months after the onset of MI: T2) exercise maintenance, peak VO2, MS, and physical activity were remeasured. The MS training group performed low-intensity MS training and walking over the second 6-month period; the control group performed walking exercise only. All patients maintained their exercise training. At T2, there were no significant differences in peak VO2 values between the MS training and control groups. There was also no significant difference in physical activity (mean number of steps per week) between the MS training and control groups. However, MS was significantly higher in the MS training group than in the control group. We concluded that unsupervised exercise training and low-level MS training performed after supervised cardiac rehabilitation may effectively maintain not only physical activity and peak VO2 but increase MS.

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. © 2013.

Background: The association of breaks in sedentary time with outcomes of physical function can vary according to the time of day. We examined the association of the diurnal pattern of breaks in sedentary time with physical function outcomes in older adults. Methods: A cross-sectional analysis was conducted among 115 older adults (≥60 years). The overall and time-specific breaks (morning: 06:00-12:00; afternoon: 12:00-18:00; evening: 18:00-24:00) in sedentary time were assessed using a triaxial accelerometer (Actigraph GT3X+). A break in sedentary time was defined as at least 1 min where the accelerometer registered ≥ 100 counts/min following a sedentary period. Five physical function outcomes were assessed: handgrip strength (dynamometer), balance ability (single leg stance), gait speed (11-meter walking), basic functional mobility (time up and go), and lower-limb strength (five times sit-to-stand). Generalized linear models were used to examine the associations of the overall and time-specific breaks in sedentary time with the physical function outcomes. Results: Participants showed an average of 69.4 breaks in sedentary time during the day. Less frequent breaks in the evening (19.3) were found than that in the morning (24.3) and the afternoon (25.3) (p<0.05). Breaks in sedentary time during the day were associated with less time on gait speed in older adults (exp (β)=0.92, 95% confidence interval [CI] 0.86-0.98; p<0.01). Time-specific analysis showed that breaks in sedentary time were associated with less time on gait speed (exp (β)=0.94, 95% CI 0.91-0.97; p<0.01), basic functional mobility (exp (β)=0.93, 95% CI 0.89-0.97; p<0.01), and lower-limb strength (exp (β)=0.92, 95% CI 0.87-0.97; p<0.01) in the evening only. Conclusion: A break in sedentary time, particularly during the evening, was associated with better lower extremity strength in older adults. Further strategies to interrupt sedentary time with frequent breaks, with an emphasis on evening hours, can be helpful to maintain and improve physical function in older adults.

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.
