    OBJECTIVES: Although neighborhood is considered to be a crucial source of social network to promote health among older adults, current findings are mostly derived from observational study designs. This study examined whether participations in event-based community programs could increase neighborhood social network and whether such increase could lead to desirable changes in mental and physical health among older adults. METHOD: This study employed quasi-experimental design. A baseline questionnaire survey was sent to residents of Tsurukabuto community aged 60 years or more (n = 1769); 1,068 responded. Community events were implemented approximately once a month for three years. Then, a three-year follow-up survey questionnaire was sent to the respondents of the baseline survey. The total number of respondents in the latter survey was 662; of the total, 173 participated in the intervention. Strong and weak ties with neighbors, mental well-being (Ikigai-9), health-related quality of life (HRQOL), and instrumental activity of daily living (IADL) were measured in the surveys. RESULTS: The path analysis revealed that intervention participation was significantly associated with changes in strong ties (standardized path coefficient = 0.12) and changes in strong ties were associated with those in Ikigai-9 scores (standardized path coefficient = 0.15). The total and indirect effects of intervention participation on Ikigai-9 scores were significant. Significant intervention effects were not observed for HRQOL and IADL scores. CONCLUSION: This study found that participation in our event-based intervention could indirectly and positively influence older adults' mental well-being through their strong ties with their neighbors.

    The aim of this study was to examine cortical thickness changes associated with a multicomponent exercise intervention combining physical exercise and cognitive training in older adults with cognitive decline. This study involved a secondary analysis of neuroimaging data from a randomized controlled trial with 280 older adults having cognitive decline who were randomly assigned to either a multicomponent exercise group (n = 140) that attended weekly 90-minute exercise and cognitive training sessions or a health education control group (n = 140). The cortical thickness and cognitive performance were assessed at the baseline and at trial completion (10 months). The cortical thickness in the frontal and temporal regions was determined using FreeSurfer software. Cognitive performance was evaluated using the Gerontology-Functional Assessment Tool (NCGG-FAT). The cortical thickness significantly increased in the middle temporal (p < 0.001) and temporal pole (p < 0.001) in the multicomponent exercise group compared with the control group. Cortical thickness changes were significantly associated with change in trail making test (TMT)-A, TMT-B, and story memory after a 10-month multicomponent exercise intervention. This study suggests that multicomponent exercise programs combining physical exercise and cognitive training have important implications for brain health, especially in providing protection from age-related cortical thinning.

    This study examined whether satisfaction with social interactions and the number of people interacted with during walking groups is associated with affective responses among older adults. Twenty-six older adults were asked to participate in five walking group sessions. The participants walked together for 40-50 min. In every session, the participants reported their affective responses to walking (positive engagement, tranquility, and negative affect), their level of satisfaction with the social interactions experienced, and the number of people interacted with during the walk. The available data were from 107 person-sessions. Multilevel models revealed that, although a higher number of people interacted with was not significantly associated with improvements in any affective responses, higher satisfaction with the interactions was significantly associated with improvements in positive engagement at both the within- and between-person levels. This study found that higher satisfaction with the interactions was associated with desirable affective responses among older adults.

    This study examined whether routine work time was associated with exercise time, moderate-to-vigorous physical activity (MVPA), and step counts (SC) among middle-aged and older adults. A 7-day diary survey was conducted with 158 adults, and 138 participated in the 1-year follow-up survey for measuring routine work time and exercise time. An accelerometer was used to measure MVPA and SC, and a questionnaire assessed perceived barriers and self-efficacy. Daily analyses revealed that while longer routine work time was associated with shorter exercise time after adjusting for perceived exercise barriers and exercise self-efficacy, it was associated with higher amounts of MVPA and SC. Longitudinal analysis showed that increased routine work time was associated with decreased exercise time and increased MVPA and SC. Changes in perceived barriers and self-efficacy did not mediate these associations. Actual lack of time would inhibit exercise behavior independently of perceived barriers and self-efficacy but elevates MVPA and SC.

    Ikigai, one of the indices of well-being, tends to decline with age because resources relating to ikigai decline. However, there are individual differences in this decline. This study tested for maintenance of ikigai among Japanese elderly, using a longitudinal study investigating the moderating role of social capital on the effects of changes in human capital on ikigai. We conducted a panel survey targeting 1,068 people (M age = 73.01 years) in 2013, and 686 people in 2017. The variables were ikigai, changes in human capital (self-rated financial status, physical health) and social capital (social networks, trust in others), educational level, and control variables. Multiple regression analyses revealed the interaction effects of changes in physical health and changes in social networks (strong ties, weak ties) on follow-up ikigai. Post hoc analyses indicated that declines in physical health predicted declines in ikigai among those whose social networks (strong ties and weak ties) had declined in the 4-year study, but these relationships were not significant among those whose social networks had increased. The results suggest that older adults can weaken the adverse effect of a decline in human capital on ikigai by maintaining or increasing social networks.

    This study examined the association between the estimated glomerular filtration rate (eGFR) and disability incidence according to sedentary time in community-dwelling Japanese older adults. This prospective cohort study sampled 5,104 community-dwelling older adults (≥65 years) enrolled in a health promotion study in a general population. The participants (n = 4,457; ≥65 years) were monitored for inclusion in the long-term care insurance system for 4 years. This study used blood samples to assess eGFR. Cox proportional regression analysis was used to determine predictors of disability. In total, 461 participants (10.3%) became newly certified as needing long-term care insurance services. Cox regression models were adjusted for multiple confounders: eGFR < 45 ml/min/1.73 m2 (hazard ratio = 1.741, 95% confidence interval [1.193-2.539]) and eGFR < 45 ml/min/1.73 m2 with high sedentary time (≥8 hr) (hazard ratio = 4.367, 95% confidence interval [2.021-9.438]) remained significantly associated with disability incidence. Our findings suggest that in the case of chronic kidney disease, the disability incidence rate may be affected by sedentary time.

    OBJECTIVES: This study aimed to examine the effectiveness of a multicomponent intervention combining physical, cognitive, and social activities developed to promote community activity in improving cognitive function in older adults with mild cognitive impairment (MCI). DESIGN: Single-blind randomized controlled trial. SETTING: A total of 83 Japanese older adults with MCI participated in the study from April to September 2017. INTERVENTIONS: Participants were randomly assigned to either the multicomponent intervention group (n = 41), attending 90-minute physical, cognitive, or social activity sessions using community resources twice weekly, or the health education control group (n = 42). OUTCOMES: The primary outcomes were cognitive functions, and the secondary outcomes were grip strength, walking speed, depressive symptoms, physical activities, number of outdoor activities, and conversation time. RESULTS: Analysis using linear mixed models revealed significantly greater improvements in the intervention group in spatial working memory (p =  0.024) following intervention compared with the control group. Time spent in moderate-to-vigorous physical activity (p =  0.048) and step count (p =  0.059) decreased from the baseline post-intervention in the control group, whereas the baseline was maintained in the intervention group. No significant between-group differences were found post-intervention in the other primary and secondary outcomes. CONCLUSIONS: This study showed that a 24-week multicomponent intervention program was effective in improving spatial working memory and maintaining physical activity in older adults with MCI. A follow-up investigation is required to determine whether continuation of physical, cognitive, and social activity can prevent dementia or reverse MCI in older adults.

    Background: We used longitudinal cohort data to investigate whether hearing problems and low levels of social activity lead to a higher incidence of disability among community-dwelling older adults. Methods: Participants were 4576 older adults (47.8% male, mean age 75.9 years) who met the study inclusion criteria. Longitudinal data on the incidence of disability were monitored monthly. Disability was defined as Japanese long-term care insurance certification for personal support or care for 2 years following the baseline assessment. Hearing problems were measured using the Hearing Handicap Inventory for the Elderly and for Adults - Screening version. Participants completed a questionnaire that included five questions on daily social activities. Results: In the adjusted model that included potential covariates, participants with co-occurring hearing problems and low participation rates in social activities were at higher risk of developing a disability than participants without hearing problems and low levels of social activity (hazard ratio [HR] = 2.13, 95% confidence interval [CI]: 1.31–3.45). The second highest risk of developing a disability was found for those with low levels of social activity alone (HR = 1.98, 95% CI: 1.26–3.11), and the third highest for those with hearing problems alone (HR = 1.38, 95% CI: 1.07–1.77). Conclusions: Hearing problems and a lack of social activity were independent risk factors for developing a disability. Co-occurring hearing problems and low levels of participation in social activities represented the largest risk factor for disability.

    Objective: Although previous studies have shown that good access to public transportation is positively related with physical activity, the moderators of this relationship have not been explored sufficiently in older adults. It is possible that driving status could moderate this relationship. The present study examined whether the objectively measured distance between public transportation and the home was associated with physical activity levels, and whether this association was moderated by driving status among Japanese older adults. Method: In this cross-sectional study, participants (n = 2,878) completed questionnaires and wore accelerometers for at least 7 days, to measure their average daily step counts and minutes spent engaging in moderate-to-vigorous physical activity. Road network distances between the home and the nearest bus stop or train station were measured using geographic information systems. Driving status was assessed using questionnaires. Results: Multiple regression analyses stratified by driving status revealed that, among nondrivers, living further away from public transportation was associated with higher step counts (β = 0.08, p < .001) and moderate-to-vigorous physical activity (β = 0.06, p = .029). Among drivers, living closer to public transportation was significantly associated with higher moderate-to-vigorous physical activity levels (β =-0.05, p = .042). Conclusion: Despite the small effect sizes, the direction of the association between distance from public transportation and physical activity was different for current drivers and nondrivers. These findings imply that good access to public transportation does not positively relate with greater engagement in physical activity among nondriving older adults. Shorter distances to public transportation might reduce opportunities for engaging in physical activity for them.

    AimGoing outdoors more frequently is beneficial for maintaining and improving health-related quality of life (HRQOL) among older adults. However, individual differences can alter the effects of going outdoors. The present study aimed to examine whether relationships between going outdoors and HRQOL were moderated by living alone and employment status.MethodsThe present study was a secondary analysis of 14-month prospective data (n = 613). Variables used in this study were baseline data on the frequency of going outdoors, HRQOL (physical and mental component summary scores assessed using the Japanese version of the Medical Outcomes study Short Form 8-Item Health Survey), living alone, employment status, potential confounders (sex, age, educational level and instrumental activities of daily living) and follow-up data on HRQOL.ResultsMixed models showed that the interaction term of going outdoors and currently living alone on both the physical and mental component summary and that of going outdoors and current employment status on the mental component were significant. Stratified analyses showed that going outdoors more frequently predicted the physical and mental component summary among those who lived with others, and the mental component summary among those who were unemployed.ConclusionsThese results show that the influence of going outdoors on HRQOL was moderated by living alone and employment status. Going outdoors more frequently might be important for the maintenance of HRQOL, especially among unemployed older adults living with others. Geriatr Gerontol Int 2018; 18: 640-647.

    Aim: The aim of the present study was to investigate the relationship between physical activity (PA) and depressive symptoms in community-dwelling older Japanese adults. Methods: A cross-sectional study design was used to obtain data from 3191 community-dwelling older Japanese adults aged 70–95 years. Depressive symptoms were assessed using self-reported scores on the Geriatric Depression Scale-15. PA was objectively measured using an accelerometer worn for a maximum of 40 days, and average daily durations of light-intensity PA (LPA), moderate-to-vigorous intensity PA (MVPA) and step count were calculated. PA was compared between participants with and without depressive symptoms by carrying out analysis of covariance and multivariable logistic regression analysis adjusted for all covariates by using propensity scores. Results: Depressive symptoms were present in 598 participants (19.6%). A comparison of propensity-score adjusted PA showed that step count (5059.6 ± 53.7 vs 5003.0 ± 112.1 count/day P = 0.652) and moderate-to-vigorous intensity PA duration (23.0 ± 0.4 vs 23.8 ± 0.7 min/day P = 0.358) were not significantly different between participants with and without depressive symptoms, respectively. However, participants without depressive symptoms had a significantly higher LPA duration than those with depressive symptoms (39.4 ± 0.3 vs 37.3 ± 0.7 min/day, respectively P < 0.01). Conclusions: The present results suggest that individuals with lower LPA have a higher risk of depressive symptoms. These findings imply that PA recommendations, especially for older adults, should emphasize LPA, which appears to be especially effective at preventing depressive symptoms.

    AimStrengthening neighborhood social networks is important for promoting health among older adults. However, effective intervention strategies aimed at increasing older adults' social networks have not yet been established. The present study examined whether a university-led community intervention that provided communication opportunities could increase older Japanese adults' neighborhood social networks.MethodsThe present study used a quasi-experimental design. Before the intervention, using postal mail, we carried out a baseline questionnaire survey that was sent to all people living in the Tsurukabuto community aged 60 years (n = 1769), of whom 1068 responded. For the community intervention, 18 event-based programs were provided over the course of 1 year at Kobe University. Academic staff at Kobe University organized all the programs. During the program, social interactions among participants were promoted. A follow-up survey was distributed to those who responded to the baseline survey, and 710 individuals answered the question about their participation in the intervention programs (138 respondents were participants, 572 were non-participants). The neighborhood social network was measured in both the baseline and follow-up surveys.ResultsAnalysis of covariance showed that the changes in neighborhood social network among participants in the program was significantly higher than the changes among non-participants (P = 0.046) after adjusting for the baseline score of social network.ConclusionsThe present study found that participants of the intervention expanded their neighborhood social network, but non-participants did not. This finding shows that community interventions using university resources could increase older adults' neighborhood social networks. Geriatr Gerontol Int 2018; 18: 462-469.

    AIM: To evaluate the relationship between kidney function without diabetes and components of the frailty phenotype in community-dwelling Japanese older adults. METHODS: Participants were 8343 residents who completed baseline assessments, classified into four categories according to eGFR. Frailty status was defined using five criteria: (i) slow gait speed; (ii) muscle weakness; (iii) low physical activity; (iv) exhaustion; and (v) unintentional weight loss. RESULTS: After multivariate adjustment, participants with the lowest kidney function were at higher risk of frailty (OR 1.57, 95% CI 1.02-3.50) than those with normal kidney function. In addition, after adjustment for multiple confounders, estimated glomerular filtration rate <30 was associated with a greater risk of the individual frailty components of weight loss (OR 2.14, 95% CI 1.11-4.12), low physical activity (OR 1.35, 95% CI, 1.01-2.54) and slowness (OR 1.82, 95% CI 1.36-3.77) compared with estimated glomerular filtration rate ≥60. CONCLUSIONS: Lower kidney function was associated with a higher risk of weight loss, low physical activity and slowness among community-dwelling Japanese older adults.

    This study aimed to examine whether the expectation for physical activity to minimize dementia risk was associated with physical activity level and whether this association was moderated by perceived high value of dementia prevention among older adults. Participants (n = 2,824) completed questionnaires and wore accelerometers to measure their average daily steps and levels of physical activity. The expectation for physical activity to minimize dementia risk, perceived value of dementia prevention, and potential covariates (expectation of other desirable outcomes, demographics, and health-related factors) were also measured. The main effects of the expectation and perceived value and their interaction were not significant for physical activity variables in generalized linear models. These findings indicate that expecting physical activity in minimizing dementia risk might not be sufficient to influence physical activity behavior regardless of perceived high value of dementia prevention among older adults.

    Aim: To develop intervention strategies that promote screening for cognitive impairment, it is essential to identify the modifiable predictors for participation in screening. The present study aimed to examine whether a shorter distance to the screening site predicted participation in screening for cognitive impairment, and whether interactive effects of the distance and psychological factors on the participation would be observed among community-dwelling older adults. Methods: The study used a prospective design. After a baseline questionnaire survey, participation in screening for cognitive impairment was followed for 6 months (n = 9616). The distance to the screening site was measured by road distance from each residential address and categorized into four groups (< 1 km, 1–1.99 km, 2–2.99 km, ≥3 km). The questionnaire measured psychological factors (behavioral intention and perceived benefits of screening), driving status and demographic factors. Results: A logistic regression analysis showed that compared with the < 1 km group, the 2–2.99 km (adjusted odds ratio 0.62, P = 0.040) and ≥3 km (adjusted odds ratio 0.54, P = 0.015) groups did not participate in screening after adjusting for psychological and demographic factors, and driving status. The interaction of the distances and psychological factors on participation were not significant. Conclusions: The distance to the screening site predicted participation in cognitive impairment screening among older adults regardless of their psychological status. This finding shows that improving access to screening sites would be effective for promoting screening for cognitive impairments among both low and highly motivated older adults.

    目的:斜面市街地に住む高齢者を対象に,近隣の坂道への認識が,活動的な移動習慣と関連しているかどうかを検討した。

    方法:本研究は横断研究であった。神戸市灘区鶴甲地区の1,021名へ2017年に質問紙調査を行い,693名(67.9%)が回答した。回答者のうち,65歳以上であり,移動能力に大きな制限がなく,かつ,分析項目に欠損のない,337名(男性155名,女性182名)を解析対象とした。活動的な移動習慣は,徒歩または自転車による地区外への週1日以上の外出として評価した。坂道に対する認識として,近所には坂が多く移動が大変と認識しているかどうかを質問した。基本属性等として,性別,年代,居住形態,経済的ゆとり,自動車・バイクの運転,運動実施,過体重,膝痛,心理的苦痛を取り上げた。活動的な移動習慣を従属変数,坂道に対する認識と基本属性等を独立変数としたポアソン回帰分析を行った。

    結果:解析対象の21.2%が活動的な移動習慣を有していた。ポアソン回帰分析の結果,坂道を否定的に認識している者(調整有病割合比=0.64,95%信頼区間=0.42-0.96)は,否定的に認識していない者よりも,活動的な移動習慣を有していない傾向にあった。

    結論:坂道に対する認識が否定的ではない高齢者のほうが,活動的な移動習慣を有していた。このことは,斜面市街地に住む高齢者において,近隣の坂道に対する否定的な認識を取り除くことが活動的な移動習慣の形成に影響する可能性があることを示している。

    Background: No existing Web-based nutrition education interventions have been evaluated in light of socioeconomic status just in Japan. Objective: The aim was to investigate the effect of a Web-based intervention program on reducing vegetable intake disparities between low-and middle-income Japanese adults. Methods: In this randomized controlled trial, participants were assessed at three time points-baseline, postintervention (5 weeks later), and a follow-up after 3 months-from October 2015 to March 2016. We collected data via a Japanese online research service company from 8564 adults aged 30 to 59 years. Participants were stratified according to national population statistics for gender and age, and randomly selected. They were then randomly allocated into intervention (n=900) and control (n=600) groups such that both groups contained an equal number of individuals with low and middle income. The intervention program encouraged behavior change using behavioral theories and techniques tailored to their assumed stage of change. The outcome was vegetable intake servings per day (1 serving being approximately 70 g). Results: Out of 900 participants who started, 450 were from the middle income group (of which 386 or 85.7% completed the intervention), and 450 were from the low income group (of which 371 or 82.4% completed). In the intervention group, vegetable intake increased in the low-income participants from baseline to postintervention (0.42 servings, 95% CI 0.11-0.72). A two-way analysis of variance showed that low-income participants had significant main effects of group (eta(2)=0.04, P=.01) and time (eta(2)=0.01, P<.001), and a significant interaction (eta(2)=0.01, P=.009). Middle-income participants also had a significant main effect of time (eta(2)=0.01, P=.006) and a significant interaction (eta(2)=0.01, P=.046). Conclusions: This Web-based nutritional education intervention could fill the vegetable intake gap between low-and middle-income adults in Japan, and is expected to prevent noncommunicable and lifestyle-related diseases. Further intervention program improvements are necessary to maintain and increase vegetable intake for other groups.

    AIM: The aim of the present study was to evaluate the relationship between kidney function with concomitant diabetes or hypertension and frailty in community-dwelling Japanese older adults. METHODS: The participants were 9606 residents (community-dwelling Japanese older adults) who completed baseline assessments. The estimated glomerular filtration rate (mL/min/1.73 m2 ) was determined according to the serum creatinine level, and participants were classified into four mutually exclusive categories: ≥60.0 (normal range), 45.0-59.9, 30.0-44.9 and <30.0 mL/min/1.73 m2 . Frailty status was defined using five criteria as described by Fried: slow gait speed, muscle weakness, low physical activity, exhaustion and unintentional weight loss. Participants who met three, four or five criteria satisfied the definition of having frailty. Multivariate logistic regression was used to examine the relationships between estimated glomerular filtration rate and frailty. RESULTS: After multivariate adjustment, participants with lower kidney function (estimated glomerular filtration rate <30.0 mL/min/1.73 m2 ) were more frail (odds ratio [OR] 1.90, 95% confidence interval [CI] 1.01-3.59). In addition, individuals with a history of diabetes (OR 2.76, 95% CI 1.21-8.24) or hypertension (OR 2.53, 95% CI 1.45-5.12) showed a significantly increased risk of frailty in the lower kidney function group, regardless of multivariate controls. Furthermore, the analyses showed an even greater increase in the risk of frailty in patients with a history of both diabetes and hypertension (OR 3.67, 95% CI 1.13-14.1) CONCLUSIONS: A lower level of kidney function was associated with a higher risk of frailty in community-dwelling Japanese older adults.

    Aim: Objective measurements of outdoor time are essential to establishing evidence about the health benefits of going outdoors among older adults, lib better understanding the health benefits of going outdoors, clarification of potential mediators to connect going outdoors with health benefits is necessary. The present study aimed to investigate associations of objectively-measured outdoor time with older adults' physical and psychological function, and examine the mediating role of physical activity on these associations. Methods: Baseline data from a randomized control trial of physical activity among older adults with global cognitive impairment was used. Data from 192 participants were analyzed. Measures included steps-per-day, objectively-measured outdoor time per day using global positioning systems, physical function (cardiorespiratory fitness, lower-extremity strength), psychological function (depression, well-being) and basic factors. Results: Path analysis showed that outdoor time was significantly associated with steps-per-day (path coefficient = 0.23) and depression (path coefficient = 0.16). Outdoor time was not directly associated with cardiorespiratory fitness, lower extremity strength and well-being. However, steps-per-day was associated with cardiorespiratory fitness (path coefficient= 0.18), lower-extremity strength (path coefficient = 0.22) and well-being (path coefficient = 0.14). Conclusions: We found that objectively-measured outdoor time was indirectly associated with physical function, and both directly and indirectly with psychological function through physical activity among older adults. This finding indicates that going outdoors influences older adults' health outcomes, and is mainly mediated by physical activity

    Aim: Detecting cognitive impairment in the earlier stages is important for preventing or delaying dementia. To develop intervention strategies that promote screening for cognitive impairment, it is essential to identify the modifiable predictors for participation in screening. The present study examined whether participation in screening for cognitive impairment was predicted by the constructs of the health belief model, dementia worry and behavioral intentions to undergo screening among older adults. Methods: The study used a prospective design. After a baseline questionnaire survey, participation in screening for cognitive impairment was followed for 6 months (n= 10 023). Participation in the screening, constructs of the health belief model (perceived susceptibility to dementia, perceived severity of dementia, perceived benefits of screening, perceived barriers to screening), dementia worry, behavioral intentions and demographic factors were measured. Results: A path analysis showed that the behavioral intention to undergo screening (path coefficient= 0.29) directly predicted participation in screening for cognitive impairment, whereas other psychological and demographic factors did not directly predict participation. The behavioral intention was explained by the perceived benefits of screening (path coefficient = 0.51), perceived barriers to screening (path coefficient= -0.19) and perceived susceptibility to dementia (path coefficient = 0.16). Conclusions: Participation in screening for cognitive impairment was positively predicted by higher behavioral intention to undergo screening. In turn, this behavioral intention was mainly predicted by the perceived benefits of screening among older adults. These findings suggest that emphasizing the perceived benefits and encouraging behavioral intentions might promote participation in screening for cognitive impairment.

    BACKGROUND: The aim of this study was to describe the age-dependent changes in the parameters of physical performance and body composition in Japanese older adults who are independently dwelling in the community. We also examined whether the age-dependent changes differ among physical performance and body composition parameters. METHODS: Cross-sectional data from 10 092 community-dwelling older adults (mean age 73.6 years; 5296 women) were analyzed. The measures of physical performance included hand-grip strength, the five-times-sit-to-stand test, and walking speed. Body composition parameters (body weight, fat mass, and appendicular skeletal muscle mass) were measured with a bioelectrical impedance analyser. Correlations between age and the physical performance and body composition parameters were tested. The T-scores of physical performance and body composition measurements were calculated and presented according to 5-year age groups to examine the differences in age-dependent changes in physical performance and body composition parameters. RESULTS: All physical performance measures significantly decreased with aging. The cumulative mean T-scores according to age group showed different age-dependent changes between body mass index (BMI) and appendicular skeletal muscle mass index (ASMI) (cumulative mean T-score change of BMI and ASMI of -5.7 to -2.9 and -12.7 to -12.1, respectively). The slope declines in age-associated changes were greater in grip strength (β = -0.77, 95% confidence interval = -0.82 to -0.76) for men and in walking speed (β = -0.95, 95% confidence interval = -0.99 to -0.90) for women. CONCLUSIONS: The patterns of age-dependent decreases in physical performance measures differed among parameters and between sexes. There is a possibility of a difference in the age-related slope patterns among parameters; decreases in grip strength in men and walking speed in women may be more prominent with advancing age. Furthermore, the decrease in ASMI with age is more striking than that of BMI.

    AIM: The aim of the present study was to evaluate the relationship between sedentary time and declines in kidney function among community-dwelling older adults. METHODS: Participants comprised 10 242 community-dwelling older adults who were participating in the National Center for Geriatrics and Gerontology - Study of Geriatric Syndromes. Sedentary time was determined by asking participants to record the total amount of hours usually spent sitting each day, with values divided into quartiles of 0 to <4 h (reference), 4 to <6 h, 6 to <8 h and ≥8 h of sitting time per day. The estimated glomerular filtration rate was determined according to creatinine levels, and participants were classified into two categories: ≥60.0 or <60 mL/min/1.73 m2 . RESULTS: After multivariate adjustment, the highest quartiles of sedentary time showed a higher rate of kidney function decline than those in the lowest quartile (odds ratio 1.42, 95% CI 1.02-1.37). In addition, participants with a history of cancer (odds ratio 1.18, 95% CI 1.01-1.39) or hypertension (odds ratio 1.38; 95% CI 1.07-1.60) had significantly increased risks of kidney function decline in the highest sedentary time group, regardless of multivariate control. Furthermore, analyses showed an increased risk of kidney function decline for a history of both cancer and hypertension (odds ratio 2.02, 95% CI 1.08-3.80). CONCLUSIONS: A higher level of sedentary time was associated with kidney function decline among community-dwelling older adults. Geriatr Gerontol Int 2017; 17: 730-736.

    This study examined associations between perceived neighborhood environment and physical activity among frail older adults and whether these associations are moderated by fear of falling. Participants were 238 frail older adults. Daily step counts and duration of moderate-to-vigorous physical activity were measured using an accelerometer. Participants completed the abbreviated Neighborhood Environment Walkability Scale; fear of falling and demographic and health-related factors were measured by a questionnaire. The interaction between crime safety and fear of falling was significantly associated with step count (p = .009) and moderate-to-vigorous physical activity (p = .018) in multiple regression analysis. Stratified according to fear of falling, crime safety was significantly associated with steps (p = .007) and moderate-to-vigorous physical activity (p = .030) in the low fear of falling group. The results suggest that crime safety is associated with physical activity among frail older adults, and this association is moderated by fear of falling.

    BACKGROUND: The associations between components of metabolic syndrome (MetS) and mild cognitive impairment (MCI) subtypes remain unclear. OBJECTIVE: The study aim was to identify the prevalence of MetS for MCI subtypes and to investigate sex differences in the association between MetS and MCI subtypes in older Japanese adults. METHODS: The study analyzed data from 3,312 men and women aged 70 years or more. MetS was diagnosed according to International Diabetes Federation criteria. Participants completed cognitive tests and were categorized into normal cognition, amnestic MCI (aMCI), and non-amnestic MCI (naMCI). The associations between MetS and its components and MCI subtypes were analyzed using multiple logistic regression. RESULTS: MetS prevalence was greater in participants with naMCI (men: p = 0.030; women: p = 0.040). Participants with naMCI showed higher odds ratios (OR) of MetS (men: 2.45, 95% confidence intervals (CI): 1.13-5.32; women: OR: 1.94, 95% CI: 1.12-3.39) compared with participants with normal cognition. MetS was not associated with aMCI. Analysis of MetS components showed that raised glucose (OR: 1.62, 95% CI: 1.19-2.22) and reduced high-density lipoprotein cholesterol (OR: 1.97, 95% CI: 1.25-3.12) were associated with naMCI in men. In women, raised blood pressure (OR: 1.42, 95% CI: 1.03-1.94) and raised glucose (OR: 1.32, 95% CI: 1.02-1.71) were associated with naMCI. CONCLUSION: MetS was associated only with naMCI regardless of sex, which suggests etiologic differences in MCI subtypes. We also found sex differences in the relationship between naMCI risk and MetS and its components.

    To identify the relationships between physical and/or cognitive frailty and instrumental activities of daily living (IADL) functioning in community living older persons. Cross sectional observation study. Data extracted from the 2011-2013 of the National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes (NCGG-SGS) database. A total of 8,864 older adults aged aeyen 65 years who were enrolled in the NCGG-SGS. We characterized physical frailty as limitations in three or more of the following five domains: slow walking speed, muscle weakness, exhaustion, low activity and weight loss. To screen for cognitive impairment, we used the National Center for Geriatrics and Gerontology-Functional Assessment Tool (NCGG-FAT) which included tests of word list memory, attention and executive function (tablet version of the Trail Making Test, part A and B), and processing speed (tablet version of the Digit Symbol Substitution Test). Two or more cognitive impairments indicated by an ageadjusted score of at least 1.5 standard deviations below the reference threshold was characterized as cognitive impairment. Each participant reported on their IADL status (use of public transportation, shopping, management of finances, and housekeeping) and several potential confounders such as demographic characteristics. The overall prevalence of physical frailty, cognitive impairment, and cognitive frailty, i.e. co-occurrence of frailty and cognitive impairment, was 7.2%, 5.2%, and 1.2%, respectively. We found significant relationships between IADL limitations and physical frailty (Odds Ratio (OR) 1.24, 95% confidence interval (95% CI) 1.01 to 1.52), cognitive impairment (OR 1.71, 95% CI 1.39 to 2.11), and cognitive frailty (OR 2.63, 95% CI 1.74 to 3.97). Using the NCGG-SGS frailty criteria, we found more participants with physical frailty than with cognitive frailty. The individuals with cognitive frailty had the highest risks of IADL limitations. Future investigation is necessary to determine whether this population is at increased risk for incidence of disability or mortality.

    Background: The purpose of this study was to examine the effectiveness and cost-efficiency of a tailored message intervention compared with a non-tailored message intervention for increasing colorectal cancer (CRC) screening rates among a non-adherent population, in a community-based client reminder program. Methods: After a baseline survey for psychological segmentation, 2140 eligible individuals were randomly assigned either to a group with a tailored matched-message condition (N = 356), a group with a non-tailored unmatched-message condition (N = 355), or to two control groups, one using a typical message with a professional design (N = 717) and one without a professional design (N = 712). The main outcome measure was attendance rates in a community-organized CRC screening program within five months of receiving a print reminder. Results: There was a significant difference in fecal occult blood test (FOBT) attendance rates at follow-up assessments between the tailored matched-message condition (14.0 %) and the control (9.9 %; OR = 1.48, p = 0.026), while there was no significant difference between the unmatched-message condition (11.0 %) and the control (OR = 1.12, p = 0.558), and between the matched-message condition and the unmatched-message condition (OR = 1.32, p = 0.219). The cost of a one-person increase in FOBT screening was 3,740 JPY for the tailored matched-message condition, while it was 2,747 JPY for the control. Conclusions: A tailored-message intervention for segmented individuals designed to increase CRC screening rates in a community-based client reminder program was significantly effective compared to a usual reminder, but not more effective than an unmatched message in a randomized controlled trial, and was not sufficiently effective to highlight its value from a cost perspective. Therefore, the tailored intervention including target segmentation needs to be improved for future implementation in a CRC screening program for a non-adherent population.

    AIM: Cognitive impairment can negatively affect driving performance and increase the risk of driving errors, leading to vehicle crashes. We used a population-based survey to identify the prevalence of cognitive impairments in older drivers. METHODS: A total of 10,073 older adults were enrolled in the National Center for Geriatrics and Gerontology - Study of Geriatric Syndromes. We characterized general cognitive impairment using the Mini-Mental State Examination (MMSE). We also used the National Center for Geriatrics and Gerontology-Functional Assessment Tool, which includes six tasks to assess word list memory, logical memory, attention and executive function, processing speed, and visuospatial skill. RESULTS: Just 15% of older women with moderate cognitive decline (MMSE ≤20) drove, whereas 61% of older men with moderate cognitive decline drove. Cognitively normal participants (MMSE score 27 and over) scored significantly better on six cognitive tests compared with those with mild (MMSE score 21-26) or moderate cognitive decline, and those in the mild cognitive decline group scored significantly better on six cognitive tests than those in the moderate cognitive decline group. CONCLUSION: A total of 61% of older men with moderate cognitive decline did not cease driving. These older drivers showed poor cognitive performance in multiple domains compared with those with normal and mild cognitive decline. Further studies are required to clarify the relationships between cognitive decline and car crashes in these high-risk populations.

    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.

    AIMS: Identifying the risk factors of cognitive impairment is essential for implementing effective prevention strategies for dementia. Previous studies have shown that the frequency of going outdoors is inversely associated with cognitive decline. Little research has examined whether the relationship between going outdoors and cognitive decline varies with physical functioning in older adults. The aim of the present study was to examine the relationship between going outdoors and cognitive function in older adults with and without physical function limitations. METHODS: The present study analyzed the data of 4450 individuals (aged 65 years or older) who participated in the Obu Study of Health Promotion for the Elderly. The measures were the Mini-Mental State Examination (MMSE), going outdoors (at least once a week or not), self-reported physical function limitations (with or without), and demographic and health-related factors as potential confounders. RESULTS: Analysis of covariance and post-hoc comparisons showed that although going outdoors at least once a week was associated with higher MMSE scores among older adults with limited physical function, it was not significantly associated with the MMSE scores among older adults without limited physical function. Similarly, logistic regression analyses, stratified by physical function, showed a significant association between going outdoors and MMSE (<24 points or not) among older adults with limited physical function. CONCLUSIONS: The results show that going outdoors less than once a week is associated with decreased cognitive function among older adults with limited physical function, but it is not associated with cognitive function among older adults without limited physical function.

    Background: Socioeconomic inequalities as social determinants of health are important issues in public health and health promotion. However, the association between socioeconomic status and eating behaviors has been investigated poorly in Japanese adults. To fill this gap, the present study examines the association of eating behaviors with household income and education. Methods: The sample comprised 3,137 Japanese adults (1,580 men and 1,557 women) aged 30 to 59 years who responded to an Internet-based cross-sectional survey in 2014. Data on the following eating behaviors were collected via self-report: "taking care of one's diet for health," "eating vegetables," "frequency of eating breakfast," "frequency of family breakfasts," "frequency of family dinners," "using the information on nutrition labels," and "conversations with family or friends during meals." Self-reported data on socioeconomic status (household income and education) and demographic variables (gender, age, district of residence, marital status, residence status, and employment status) were also collected. The associations between eating behaviors and household income or education were tested using binomial logistic regression analysis with eating behaviors as dependent variables and household income and education as independent variables. A trend P-value was calculated for three categories of household income (less than 3,000,000 JPY, 3,000,000-7,000,000 JPY, and over 7,000,000 JPY) and education (junior high/high school, 2-year college, and 4-year college/graduate school). Results: Higher household income and education were significantly associated with higher rates of eating vegetables, using the information on nutrition labels, and conversation with family or friends during meals in Japanese men and women. Higher household incomes were significantly associated with lower rates of frequency of family breakfasts in Japanese men and lower rates of frequency of family dinners in Japanese men and women. Conclusions: Higher socioeconomic status as indicated by household income or education was associated with eating more vegetables and conversation with family or friends during meals in Japanese men and women. Socioeconomic status should be considered in health promotion and diet improvement.

    Background: The aim of this study was to examine the association between socioeconomic position and the domains of physical activity connected with work, travel, and recreation in Japanese adults. Methods: A total of 3269 subjects, 1651 men (mean +/- standard deviation; 44.2 +/- 8.1 years) and 1618 women (44.1 +/- 8.1 years), responded to an Internet-based cross-sectional survey. Data on socioeconomic (household income, educational level) and demographic variables (age, size of household, and household motor vehicles) were obtained. To examine the associations between socioeconomic position and physical activity, logistic regression analysis was used to calculate the odds ratio (OR) and confidence interval (CI) for "active" domains of physical activity. Results: Men with a household income of >= 7 million yen had significantly lower work-related physical activity than the lowest income group (OR 0.51; 95 % CI, 0.35-0.75), but significantly greater travel-related (OR 1.37; 1.02-1.85), recreational (OR 2.00; 1.46-2.73) and total physical activity (OR 1.56; 1.17-2.08). Women with a household income of >= 7 million yen had significantly greater recreational physical activity (OR 1.43; 1.01-2.04) than the lowest income group. Their total physical activity was borderline significant, with slightly more activity in the high-income group (OR 1.36; 1.00-1.84), but no significant differences for work-and travel-related physical activity. Men with higher educational level (4-year college or higher degree) had significantly lower work-related (OR 0.62; 0.46-0.82), and greater travel-related physical activity (OR 1.33; 1.04-1.71) than the lowest educated group, but there were no significant differences in recreational and total physical activity. Women with a 4-year college or higher degree had significantly greater travel-related physical activity than the lowest educated group (OR 1.49; 1.12-1.97), but there were no significant differences in any other physical activity. There was no relation between working full time and physical activity in men, but women working full-time have significantly lower and not higher travel related physical activity. (OR 0.75; 0.59-0.96). Conclusions: This study suggests that lower socioeconomic position is associated with more work-related physical activity, and less travel-related, recreational and total physical activity, and that this was more pronounced in men than in women.

    Background: Promotion of physical activity (PA) is a key strategy to prevent non-communicable diseases. However, evidence on the effectiveness of community-wide interventions (CWIs) for promoting PA is limited. Purpose: To evaluate the effectiveness of a 3-year CWI for promoting PA in middle-aged and older adults compared with usual public health services. This study is an extension to an original 1-year investigation study. Design: Cluster randomized controlled trial with community as unit of randomization and individual as unit of analysis. Setting/participants: 12 communities in Unnan, Japan were randomly allocated to the intervention (9) or the control (3). Additionally intervention communities were randomly allocated to aerobic activity promotion (Group A), flexibility and muscle-strengthening activities promotion (Group FM), or aerobic, flexibility, and muscle-strengthening activities promotion (Group AFM), each consisting of three communities. Randomly-sampled 4414 residents aged 40 to 79 years responded to the baseline survey (74 %), and were analyzed in 2013-2014. Intervention: A 3-year CWI based on social marketing, to promote PA from 2009 to 2012. Main outcome measures: The primary outcome was a change in regular aerobic, flexibility, and/or musclestrengthening activities, defined by (1) engaging in 150 mins/week or more of walking, (2) engaging in daily flexibility activity, or (3) engaging 2 or more days/week in muscle-strengthening activities, evaluated at the individual level. Secondary outcomes were changes in specific types of PA and musculoskeletal pain. Outcomes were measured at baseline and at 1 and 3 years (2009, 2010, and 2012). Results: The CWI did not significantly increase the proportion of adults who reached recommended levels of aerobic, flexibility, and/or muscle-strengthening activities (adjusted change difference = 1.6 % [95 % CI: -3.5, 6.6]). In the subgroup analysis, compared to the controls, adults doing flexibility activity daily significantly increased in Group FM (6.3 % [95 % CI: 1.9, 10.7]). In Group A and AFM for PA outcomes and in all groups for pain outcomes, there was no significant change compared to controls. Conclusions: The CWI did not achieve significant increase in the proportion of adults who reached recommended PA levels. However, it might be effective in promoting flexibility activity in middle-aged and older Japanese.

    Our aim was to determine whether baseline measures of cognitive functioning, walking speed, and depressive status are independent predictors of limitations in instrumental activities of daily living (IADL) in older adults. The cross-sectional study involved 1329 community-dwelling adults, aged 75 years or older. At baseline, the Mini-Mental State Examination (MMSE), Symbol Digit Substitution Test (SDST), Geriatric Depressive Scale (GDS), and a word list memory task were completed, and self-reported IADLs and walking speed were recorded. The longitudinal study involved 948 participants without baseline IADL limitation, which was assessed at baseline and 15-month follow up, using the three Kihon Checklist subitems. In cross-sectional analyses, participants with IADL limitation demonstrated greater GDS scores, slower walking speeds, and lower MMSE, word list memory task, and SDST (only for women) scores relative to those without IADL limitation. In the longitudinal analyses, baseline walking speed (men: OR 0.98; women: OR 0.97, p<0.05) and word list memory task scores (men: OR 0.84; women: OR 0.83, p<0.05) in both sexes and SDST scores in women (OR 0.96, p=0.04) were independent predictors of subsequent IADL limitation. Walking speed, memory, and processing speed may be independent predictors of IADL limitation in older adults.

    This study aimed to examine the association of muscle-strengthening activity with knee and low back pain, falls, and health-related quality of life among Japanese older adults. A cross-sectional survey targeted 3,000 people. The response rate was 52% and 208 respondents did not meet the inclusion criteria. Therefore, 1,351 individuals were analyzed. Muscle-strengthening activity (exercise using equipment and body weight, lifestyle activities), knee and low back pain, falls over the past year, health-related quality of life (SF-8), and potential confounders were assessed. Individuals engaging in exercise using body weight and lifestyle activity (>= 2 days/week) were more likely to have knee pain. Engaging in exercise using equipment and body weight was associated with higher scores of general health. These results indicate that exercise using equipment and body weight might have a positive effect on health-related quality of life, but muscle-strengthening activities are associated with knee pain in older people.

    The promotion of strength training is a public health priority. Employing both self-reported and objective assessment of environmental factors is helpful for a better understanding of the environmental influences on strength-training behavior. This study aims to investigate the associations of perceived and objectively measured access to strength-training facilities with strength-training behavior. A cross-sectional questionnaire survey targeted 3,000 Japanese adults and 1,051 responded validly. Strength-training behavior, perceived access to facilities, and sociodemographic factors were assessed. Objective access to facilities was calculated using a geographic information system. Logistic regression analyses were conducted. Perceived good access to the facilities was significantly associated with strength-training behavior, whereas objective access to the facilities was not, even when adjusted for sociodemographic factors and other measures of access to strength-training facilities. Perceived access to the facilities may be a stronger predictor of strength-training behavior than objective access.

    Background: Although several studies have examined associations of perceived benefits and barriers with physical activity, no studies have focused on them corresponding to strength-training recommendations for older adults. This study examined the associations among the perceived health benefits of strength training, perceived barriers to strength straining, and stages of change for strength-training behavior in older Japanese adults. Methods: This cross-sectional survey included a random sample of 1144 adults (60-74 years) from the city of Tokorozawa. Stage of change was the independent variable, with perceived health benefits (eg, strength training can reduce body pain) and perceived barriers (eg, facilities are needed for strength training) as dependent variables. Data were analyzed by analysis of covariance and Bonferroni's multiple comparison. Results: After adjusting for demographic variables, the perceived health-benefit score for precontemplation was significantly lower than for the other four stages. The perceived barrier scores in the precontemplation and contemplation stages were significantly higher than those in the preparation and maintenance stages. Conclusions: These results suggest that information about the health benefits for older adults and about the recommended type of strength training might be useful for the development of strategies to promote strength training among older adults.

    We examined the predictive validity of a segmentation strategy based on intention and cancer worry for mammography adoption and explored key factors for promoting mammography adoption in each segment. A questionnaire survey was completed by 641 women aged 40-59 years. Among them, 559 answered a follow-up survey after 15 months. They were categorized into five segments: maintenance group (S5), higher implementation intention group (S4), higher goal intention group (S3), higher worry group (S2), or lower worry group (S1). The odds of participants in each segment adopting mammography during the follow-up period were calculated. Logistic regression analysis was conducted to identify psychological predictors (five attitudes to mammography and perceived health competence) of transition to upper segments (S1 vs. S2, S2 vs. S3, S3 vs. S4, S4 vs. S5). Compared to S5, other segments did not undertake mammography at significant rates during the follow-up. The following were significant predictors for inclusion in upper segments: Lack of importance and perceived health competence were associated with inclusion in S2; lack of importance and barriers to screening were associated with inclusion in S3; perceived health competence was associated with inclusion in S4; and lack of importance was associated with inclusion in S5. These results confirm the predictive validity of a segmentation strategy, and indicate that there might be specific key factors for each segment in promoting mammography adoption.

    Objectives This study aimed to develop a structural model for mammography adoption in Japanese middle-aged women by using constructs from the transtheoretical model (TTM), the theory of planned behavior (TPB), implementation intentions, and cancer worry. Methods Questionnaires based on items including TTM, TPB, implementation intentions, cancer worry-related variables, and demographic variables were distributed to 1000 adult women aged 40 to 59 years, with 641 subjects being used in the final analysis (response rate = 64.1%). Results Regarding the stage of adoption, 79 participants (12.3%) were at the precontemplation stage, 30 (4.7%) were at the relapse stage, 142 (22.2%) were at the contemplation stage, 88 (13.7%) were at the action stage, and 302 (47.1%) were at the maintenance stage. Our model, derived from structural equation modeling, revealed that the stage of mammography adoption was significantly affected by goal intentions, implementation intentions, perceived barriers, history of breast cancer screening, and relative risk. A logistic regression analysis revealed that goal intentions and implementation intentions significantly predicted mammography uptake within 1 year. Conclusion This study developed an integrated model constructed from TTM, TPB, implementation intentions, and cancer worry to account for mammography adoption in Japan, and also confirmed the predictive validity of the model.

    Background: We aimed to evaluate the effectiveness of a community-wide campaign (CWC) for promoting physical activity in middle-aged and elderly people. Methods: A cluster randomized controlled trial (RCT) with a community as the unit of randomization was performed using a population-based random-sampled evaluation by self-administered questionnaires in the city of Unnan, Shimane Prefecture, Japan. The evaluation sample included 6000 residents aged 40 to 79 years. We randomly allocated nine communities to the intervention group and three to the control group. The intervention was a CWC from 2009 to 2010 to promote physical activity, and it comprised information, education, and support delivery. The primary outcome was a change in engaging in regular aerobic, flexibility, and/or muscle-strengthening activities evaluated at the individual level. Results: In total, 4414 residents aged 40-79 years responded to a self-administered questionnaire (73.6% response rate). Awareness of the CWC was 79% in the intervention group. Awareness and knowledge were significantly different between the intervention and control groups, although there were no significant differences in belief and intention. The 1-year CWC did not significantly promote the recommended level of physical activity (adjusted odds ratio: 0.97; 95% confidence interval: 0.84-1.14). Conclusions: This cluster RCT showed that the CWC did not promote physical activity in 1 year. Significant differences were observed in awareness and knowledge between intervention and control groups as short-term impacts of the campaign.

    Background: Although the percentage of women who initiate breast cancer screening is rising, the rate of continued adherence is poor. The purpose of this study was to examine the effectiveness and cost-effectiveness of a tailored print intervention compared with a non-tailored print intervention for increasing the breast cancer screening rate among a non-adherent population. Methods: In total, 1859 participants aged 51-59 years (except those aged 55 years) were recruited from a Japanese urban community setting. Participants were randomly assigned to receive either a tailored print reminder (tailored intervention group) or non-tailored print reminder (non-tailored intervention group). The primary outcome was improvement in the breast cancer screening rate. The screening rates and cost-effectiveness were examined for each treatment group (tailored vs. non-tailored) and each intervention subgroup during a follow-up period of five months. All analyses followed the intention-to-treat principle. Results: The number of women who underwent a screening mammogram following the reminder was 277 (19.9%) in the tailored reminder group and 27 (5.8%) in the non-tailored reminder group. A logistic regression model revealed that the odds of a woman who received a tailored print reminder undergoing mammography was 4.02 times those of a women who had received a non-tailored print reminder (95% confidence interval, 2.67-6.06). The cost of one mammography screening increase was 2,544 JPY or 30 USD in the tailored intervention group and 4,366 JPY or 52 USD in the non-tailored intervention group. Conclusions: Providing a tailored print reminder was an effective and cost-effective strategy for improving breast cancer screening rates among non-adherent women.

    Objectives: The purpose of the study was to examine the relationships among the psychological, social, and environmental factors influencing the utilization of senior centers among older adults in Korea. Methods: A questionnaire survey was administered to two types of older adults who lived in Seoul, Korea: 262 older adults who used senior centers (3 places) and 156 older adults who did not use senior centers. Results: Our results showed clearly that the utilization of the senior centers in Korea is affected by higher self-efficacy (odds ratio [OR], 6.08 95% confidence interval [CI], 3.31 to 12.32), higher perceived benefits (OR, 1.71 95% CI, 1.16 to 4.36), lower perceived barriers (OR, 6.43 95% CI, 3.07 to 11.45), higher family support (OR, 4.21 95% CI, 2.02 to 8.77), and higher support from friends (OR, 4.08 95% CI, 2.38 to 7.81). The results also showed that participants whose total travel time was 15 to 29 minutes (OR, 2.84 95% CI, 1.21 to 3.64) or less than 14 minutes (OR, 4.68 95% CI, 3.41 to 8.41) were more likely to use a senior center than those who had to travel more than 30 minutes. Conclusions: This study showed that the utilization of senior centers in Korea is affected by psychological, social, and environmental factors, specifically by self-efficacy, perceived benefits, perceived barriers, social support, convenience of transportation, and total travel time to the senior centers. The effects of longer-term utilization of the senior centers by non-users on health-related outcomes in a large population warrant attention.

    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.

    Objective: To investigate whether awareness of the Japanese Food Guide (JFG) can promote changes in eating behaviour. Design: A longitudinal study was conducted in 2007 and 2009 by means of an Internet-based survey. Awareness status of the JFG and a sixteen-item scale for calculating eating behaviour scores were obtained. Setting: Japan. Subjects: In total, 787 Japanese adults (20-59 years) who registered with an Internet research service organization were included in the study. The respondents were divided into three groups. The respondents who were aware of the JFG in 2007 were categorized into Group 1. Those who were not aware of the JFG in 2007 were categorized into either Group 2 or Group 3. Group 2 became aware of the JFG by 2009, and Group 3 was not aware of the JFG in 2009. Results: In Group 2, the eating behaviour score increased significantly by 0.8 points from 4.7 in 2007 to 5.5 in 2009 (P=0.004). The eating behaviour score of Group 1 (6.5 points in 2007; 6.3 points in 2009) and Group 3 (3.8 points in 2007; 4.1 points in 2009) did not change significantly from 2007 to 2009. Conclusions: Awareness of the JFG promoted eating behaviour change in the Japanese population. The results indicate that awareness of nutrition information from sources such as the JFG would promote healthy eating.

    The purpose of this study was to examine the relationship between change in the perceived motivational climate created by coaches and change in goal orientations over time among Japanese high-school ice hockey players. One hundred and forty-six players completed surveys twice over the course of the athletic season. The results showed that a change in task-involving climate was positively associated with change in task orientation over the course of the season. Changes in both task-involving climate and ego-involving climate were positively associated with change in ego orientation over time. These results demonstrated that the task-involving climate created by coaches may influence not only players task goal orientations but also their ego orientation in Japanese youth sports settings. On the other hand, an ego-involving climate created by coaches may influence players' ego goal orientations.

    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.

    Objective: The purpose of the present study was to examine the relationship between the use of senior center and health-related quality of life in Korean older adults. Methods: A questionnaire survey was conducted to two types of older adults who lived in Busan, Korea: 154 older adults who used a senior center and 137 older adults who did not use a senior center. The Korean version of short-form 36-item health survey was administered to assess the health-related quality of life. Demographic variables were obtained from a questionnaire. These were gender, age, family status, marital status, education, monthly income, present illness, body mass index and physical activity. Results: The 8-domain scales of physical function and role-physical were significantly higher in the users of the senior center compared with the non-users (F=4.87, p=0.027 and F=7.02, p=0.009, respectively). The 8-domain scales of vitality was also significantly higher in the users of the senior center compared with the non-users (F=7.48, p=0.007). Conclusions: The present study showed that the users of the senior center have higher physical function, role-physical and vitality compared with the non-users. These findings suggest that although the results are unable to specify causal relationships using the senior center may lead to some improvement in health-related quality of life.

    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.

  • Influence of awareness of the Japanese Food Guide Spinning Top on eating behavior and obesity

    Kanae Takaizumi, Kazuhiro Harada, Ai Shibata, Yoshio Nakamura

    The purpose of the present study was to investigate the influence of awareness of the Japanese Food Guide Spinning Top on eating behavior and obesity in Japan. Participants were 1,558 Japanese male and female adults (40.2 +/- 12.2 years) who had been registered with a social research company. The cross-sectional questionnaire survey was conducted via the Internet in November 2007. Potential respondents were invited to complete the survey via e-mail, which contained a link to the survey Uniform Resource Locator (URL). The measures were awareness of the Japanese Food Guide Spinning Top, eating knowledge scores, eating attitude scores, and eating behaviors scores, according to the recommendations of the Health Japan 21 and the Food Balance Guide Spinning Top. Obesity was assessed by self-reported body mass index (HMI) and waist circumference. The relationships between awareness of the Japanese Food Guide Spinning Top, eating knowledge scores, eating attitude scores, eating behavior scores, and obesity were analyzed using path analysis. Path analysis revealed that awareness of the Japanese Food Guide Spinning Top was associated with BMI and waist circumference via eating behavior scores. In addition, eating knowledge scores and eating attitude scores were mediators of the association between awareness of the Japanese Food Guide Spinning Top and eating behavior scores. These results suggest that promotion of the Japanese Food Guide Spinning Top would be a useful strategy to encourage healthy eating and prevent obesity in the Japanese population.

    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, selfrated 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. © 2011 Human Kinetics, Inc.

    Aim: Oxidised low-density lipoprotein (LDL) is considered a risk marker for cardiovascular disease. However, it remains unclear whether oxidised LDL concentrations differ with the physical activity status in older adults. The purpose of this study was to examine the relationship between the amount of physical activity and oxidised LDL in older adults. Methods: Twenty-seven older adults (aged 69.9 +/- 4.3 years, mean +/- SD.; 16 female and 11 male) were analysed in the cross-sectional design. Prior to blood collection, participants were asked to wear an uniaxial accelerometer for 4 consecutive weeks to determine the physical activity status. After a 48-h period of physical activity avoidance and a 10-h overnight fast, fasting venous blood samples were obtained from each participant. Results: Fasting plasma oxidised LDL concentrations and plasma monocyte chemoattractant protein-1 concentrations were negatively correlated with the amount of physical activity (r = -0.409, p = 0.034; r = -0.385, p = 0.047, respectively). Conclusions: This study demonstrates that regular physical activity may play a protective role in the oxidation of LDL in older adults.

    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=l,08walking while commuting, working and shopping cluster 2 (N=38walking while commuting cluster 3 (N=l,25walking for exercise cluster 4 (N=l, 16walking 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.

    Background: Although the benefits of the recommended level of physical activity on reducing chronic diseases are well-established, most of the Japanese population is not sufficiently active. Thus, examining correlates is an important prerequisite for designing relevant polices and effective programs. The present study investigated psychological, social, and environmental factors associated with meeting physical activity recommendations among Japanese adults. Methods: Data were analyzed for 1,932 men and women (43.6 +/- 13.0 years), who responded to an Internet-based cross-sectional survey. Self-reported measure of physical activity, psychological (self-efficacy, pros, and cons), social ( social support, health professional advice), environmental ( home fitness equipment, access to facilities, neighborhood safety, enjoyable scenery, frequently observing others exercising, residential area), and demographic ( gender, age, marital status, educational level, household income level, employment status) variables were obtained. Based on the current national guidelines for exercise in Japan ( 23 METs.hour per week), respondents were divided into two categories-recommended and not recommended ( insufficient and inactive)-according to their estimated weekly physical activity level. An adjusted logistic regression model was utilized. Results: When adjusting for all other variables, self-efficacy ( men: OR = 2.13; 95% CI: 1.55-2.94, women: OR = 2.72; 95% CI: 1.82-4.08) and possessing home fitness equipment ( men: OR = 1.55; 95% CI: 1.14-2.10, women: OR = 1.41; 95% CI: 1.01-1.99) for both genders, social support ( OR = 1.44; 95% CI: 1.06-1.97) for men, and enjoyable scenery ( OR = 1.60; 95% CI: 1.09-2.36) for women were positively associated with attaining the recommended level of physical activity. In women, cons ( OR = 0.47; 95% CI: 0.33-0.67) and living in rural areas ( OR = 0.50; 95% CI: 0.25-0.97) were negatively associated with meeting the physical activity recommendations. Conclusion: In the psychological, social, and environmental domains, significant correlates of attaining the recommended level of physical activity were observed. Men and women had different patterns of psychological, social, and environmental correlates. These findings suggest that an intervention design that accounts for those correlates may more effectively promote physical activity among Japanese adults.

    寿命と健康寿命の差,つまり自立した生活が困難な期間は約10年ある。WHO(2002)は自立した生活が困難となってもウェルビーング,生活の質(QOL)を維持するには,個人的なことがらを自己決定(意思決定)できる「自律」が重要とであるとしている。現在,ビッグデータや人工知能による高齢期の自律支援が進められている。しかしながら人の思考は合理的ではなく,選択や判断の際には認知バイアス(非合理的な選択の偏り)が生じる。特に高齢期では加齢に伴い合理的判断の基盤となる認知機能が低下するため,どれだけ客観的・合理的な情報であっても認知バイアスを考慮した情報提示でなければ,適切な判断や行動に結びつかない。しかしながら,高齢者の自律支援において,どのような情報提示のあり方が最適なのかついて,十分な検討がなされておらず,確立された手法も存在しない。 そこで本年度は,特にWebを介した購買行動に着目し,商品の価格,出品者の顔写真の表情,商品に対する他者の評価といった情報が,高齢者の商品選択に及ぼす影響について検討した。 高齢者100名(平均年齢=71.74歳, SD=3.86)を対象とし,商品選択課題,認知機能検査(WAIS-Ⅳ)を実施した。 その結果,出品者のポジティブな表情は他の条件(ニュートラル,ネガティブ,顔写真なし)に比べて購買意欲を促進する効果があることが示された。価格については,高価格条件が平均価格,低価格条件よりも有意に低い購買意欲を示したが,低価格条件と平均価格条件の間に有意差はみられなかった。商品に対する他者の評価については,サービス提供者の表情がネガティブであり,また高額であるにも関わらずレビュー評価の高い物件に対し不信感を抱くことが示された。また,認知機能との関連性を検討したところ,認知機能が高い人は表情よりも定量的に評価が可能である価格などの条件を重視していた.

    感情調整機能は,自立した生活が困難となる人生の最終段階である約10年間(エンド・オブ・ライフ)の心理的安寧や生活の質(QOL)を左右する最も重要な機能の一つである。身体的,認知的機能の多くは加齢とともに低下するが,感情のコントロールを担う感情調整機能は加齢による低下がみられずむしろ向上する。 高齢期の感情調整機能は低下しないのか?を明らかにするための実験と,感情調整機能が人間関係の喪失,社会的役割の喪失,健康の喪失にどのように影響するのか?を明らかにするための調査を実施した。 実験では,65歳以上の高齢者100名(平均年齢71.74歳, SD=3.85)を対象とし,感情調整機能の測定,認知機能の検査(WAIS -Ⅳ),処理される情報の質の評価として自伝的記憶課題,遺伝子解析のための唾液のサンプリングを行った。その結果,感情調整と種々の認知機能検査結果との間に関連性は認められなかった。一方で,普段の生活の中でよく想起される記憶の感情価,重要度,鮮明度といった指標と感情調整には関連性が認められた。これらの結果は,認知機能のパフォーマンスではなく,どのような情報を思い出し処理するかといった情報の質が感情調整と関連していることを示唆している。 調査では, 20-70代の936名を対象とし,感情調整,社会的つながり,孤独感の測定を実施した。その結果,男性よりも女性の方が感情調整を頻繁におこなうこと,社会的つながりが多い人は感情調整の頻度が高いこと,感情調整をおこなうことで孤独感が低下すること,加齢に伴い感情調整の頻度は低下をすることが示唆された。
