• Does Future Time Perspective Moderate Associations of Instrumental and Affective Attitude With Exercise Behavior? A Three-Wave Longitudinal Survey Among Japanese Older Adults

  Kazuhiro Harada, Kouhei Masumoto, Shuichi Okada

  Abstract Objectives To develop effective promotion strategies for exercise behavior in older adults, it is essential to identify the psychological determinants. Previous studies investigated affective and instrumental attitudes as determinants. However, from the conceptual assumptions of socioemotional selectivity theory, affective attitudes might be more influential on the exercise behavior of older adults with an expansive future time perspective, whereas instrumental attitudes would be more influential on those with limited perspectives. This study examined whether the associations of affective and instrumental attitudes with behavioral intention and exercise behavior differed according to future time perspective among older Japanese adults. Methods Data were obtained from a 3-wave longitudinal questionnaire survey of 886 individuals (Wave 1: December 2017–January 2018; Wave 2, 1-year follow-up; Wave 3, 3-year follow-up). Using the data on exercise behavior, affective and instrumental attitudes, and behavioral intention at each wave, and the data of future time perspective and demographic factors at Wave 1, this study performed multiple regression analyses and a multigroup cross-lagged model. Results Affective attitude was a significant predictor of behavioral intention regardless of future time perspective. Although instrumental attitude significantly predicted behavioral intention among those with a lower future time perspective, it did not predict behavioral intention among those with middle-to-higher future time perspective. Regardless of future time perspective, affective attitude, but not instrumental attitude, significantly predicted exercise behavior. Discussion Unlike the socioemotional selectivity theory, this study found that affective attitude was more influential on exercise behavior than instrumental attitude regardless of future time perspective among them.

• Social network and health behaviors among Japanese older adults: a three-wave longitudinal study

  Kazuhiro Harada, Kouhei Masumoto, Shuichi Okada

  Summary Identifying modifiable determinants of behavior is essential for developing effective strategies to promote health behaviors among older adults. Although social networks are potentially modifiable determinants of health behaviors, their longitudinal associations have not been established in previous studies. The present study examined whether a larger social network is associated with higher dietary variety, longer time spent exercising and shorter time spent viewing TV among older adults. This is a longitudinal study. The data of 908 Japanese older adults were obtained through a three-wave questionnaire survey (Wave 1, December 2017 to January 2018; Wave 2, after 1 year; Wave 3, after 3 years) and analyzed. In each wave of the survey, dietary variety (dietary variety score), exercise time (hours per day), TV viewing time (hours per day) and social network (family and friend subscales of the Japanese version of the abbreviated Lubben Social Network Scale) were measured. The present study used latent growth, cross-lagged and simultaneous effect models to investigate the longitudinal associations of family and friend social networks with dietary variety, exercise time and TV viewing time. However, these models did not show clear and robust associations. Whether social networks are determinants of health behaviors among older adults remains inconclusive.

• A non-pharmacological multidomain intervention of dual-task exercise and social activity affects the cognitive function in community-dwelling older adults with mild to moderate cognitive decline: A randomized controlled trial

  Sangyoon Lee, Kenji Harada, Seongryu Bae, Kazuhiro Harada, Keitaro Makino, Yuya Anan, Takao Suzuki, Hiroyuki Shimada

  The present study aimed to determine the impact of a 10-month multidomain program using dual-task exercise and social activity conducted at a community-based facility on improved cognitive function in older adults with mild to moderate cognitive decline. The participants included 280 community-dwelling older adults (age 71–91 years) with mild to moderate cognitive decline. The intervention group exercised for 90 min/day, once a week. Their routine included aerobic exercise and dual-task training which cognitive tasks were performed in combination with exercise. The control group attended health education classes thrice. Before and after the intervention, we measured their cognitive function, physical function, daily conversation, and physical activity. The mean adherence rate of the intervention class was 83.0%. According to a repeated-measures multivariate analysis of covariance in an intent-to-treat analysis, logical memory and 6-min walking distance demonstrated a significant time and group interaction effect. Regarding daily physical activities, we observed significant differences in the daily step count and moderate-to-vigorous physical activity in the intervention group. Our non-pharmacological multidomain intervention resulted in a modest improvement in the cognitive or physical function and building health behavior. It may be a helpful program with a potential role in preventing dementia. Clinical Trial Registration: http://clinicaltrials.gov Identifier ID: UMIN000013097.

• Does health literacy moderate the psychological pathways of physical activity from guideline awareness to behavior? A multi-group structural equation modeling

  Takayuki Tajima, Kazuhiro Harada, Yuko Oguma, Susumu S. Sawada

  Abstract Background Awareness, knowledge, beliefs, and behavioral intentions of physical activity (PA) guidelines may be important mediating factors for promoting PA. However, these pathways of the psychological process to PA behavior have not been examined. These pathways may differ depending on health literacy levels. This study investigated the pathways to PA, from guideline awareness to behavior, and further examined whether they differed by health literacy. Methods A cross-sectional study was conducted with 7,000 Japanese participants aged 20–69 years. The participants were registered with an Internet survey company. Participants’ awareness, knowledge, beliefs, and behavioral intentions regarding the PA guidelines of Japan, the volume of moderate-to-vigorous intensity PA, activity level, and health literacy were examined through a questionnaire. The PA pathways, from guideline awareness to behavior, were examined by structural equation modeling (SEM), with PA behavior as the dependent variable. Multi-group SEM was conducted to examine the moderating effect of health literacy on PA pathways. Health literacy scores were dichotomized into high and low groups in multi-group modeling by the median split. Results SEM revealed that PA guideline awareness directly affects PA behavior and has certain indirect effects through the mediation of knowledge, beliefs, and behavioral intentions. Furthermore, the multi-group SEM showed that the proportion of indirect effects (path coefficient [PC]: 0.11, 95% confidence interval [CI]: 0.10–0.13) was higher than direct effects (PC: 0.07, 95%CI: 0.03–0.11) in the high-health literacy group. In contrast, the proportion of direct effects (PC: 0.22, 95%CI: 0.15–0.30) was higher than indirect effects (PC: 0.06, 95%CI: 0.05–0.07) in the low-health literacy group. Conclusions PA guideline awareness is both directly and indirectly associated with PA behavior, mediated by psychological pathways of knowledge, beliefs, and behavioral intentions, and influenced by health literacy. These results suggest that health literacy should be considered when implementing PA guideline-based interventions.

• Current status of awareness, knowledge, beliefs, and behavioral intentions regarding the Japanese physical activity guidelines and their relationship with physical activity and sedentary behavior

  田島 敬之, 原田 和弘, 小熊 祐子, 澤田 亨

  Objective This study clarified the current status of awareness, knowledge, beliefs, and behavioral intentions regarding the Japanese physical activity guidelines (Active Guide) and their relationship with physical activity, sedentary behavior, and the participants' characteristics.Methods A cross-sectional study was conducted with 7,000 participants aged 20-69 years registered with an online survey company. Awareness, knowledge, beliefs, and behavioral intentions regarding the Active Guide were examined. Awareness was assessed by unprompted and prompted recall. Knowledge was assessed by numerical responses to "the recommended daily activity time (18-64 years/65 years and older)" and "physical activity time to be increased (plus-ten)," respectively. To survey the beliefs and behavioral intentions, we created a 5-point scale for the Active Guide. For physical activity, the amount of moderate-to-vigorous intensity physical activity was calculated from the Japan Public Health Center-based prospective Study (JPHC study) questionnaire. Physical activity level was calculated from the standard specific medical checkup and health guidance questionnaire. For sedentary behavior, the Japanese version of the International Physical Activity Questionnaire (IPAQ) was used. The dependent variables were awareness, knowledge, beliefs, and behavioral intentions. The independent variables were physical activity, sedentary behavior, and the participants' characteristics (gender, age, body mass index, marital status, educational background, work status, and household income). After descriptive statistics were measured, a logistic regression analysis was performed to examine the associations.Results Unprompted and prompted recall of the Active Guide were 1.7% and 5.3-13.4%, respectively. Those with knowledge of it scored 37.2%, 7.0%, 24.8%, and 2.6% for recommended daily activity time (18-64 years), daily physical activity time (65 years and older), plus-ten, and all three items answered correctly, respectively. The median (interquartile range) score of the beliefs was 21 (16-25) points (32-point scale). Those with behavioral intentions scored 51.4% for "recommended daily activity" and 66.9% for "plus-ten." Logistic regression analysis showed that awareness, knowledge, beliefs, and behavioral intentions were positively associated with moderate-to-vigorous intensity physical activity and level. The results were inconsistent for sedentary behavior. Although personal characteristics differed based on assessment item, they were mainly associated with age, education level, employment, and household income.Conclusions This study revealed that the number of people who had awareness and knowledge of the Active Guide remained low. Those with awareness, knowledge, beliefs, and behavioral intentions were more physically active. However, the results for sedentary behavior were not consistent. Hence, further research is required to understand this tendency. A future longitudinal study is also required.

• The Development of the Psychological Determinants of Exercise Questionnaire for Japanese Older Adults: A Questionnaire Based Upon the Theoretical Domains Framework

  Robert A.J. Walker, Kazuhiro Harada

  Japan has become a super-aged society. To overcome the negative implications of this, practitioners are increasingly using exercise-based interventions to reduce the requirement for long-term care among Japanese older adults. However, no comprehensive means of assessing the wide range of exercise behavioral determinants exists for this population. Thus, the principle aim of this study was to develop a questionnaire based upon the theoretical domains framework—a framework that has synthesized a wide range of behavior change theories. Completed responses were received from 1,000 Japanese older adults who resided in the Kansai area of Japan. Findings were suggestive of good reliability and validity for seven unique psychological determinants of exercise. This study was the first to provide a measurement tool related to a distinct range of psychological determinants of exercise among Japanese older adults.

• Three-year effects of neighborhood social network intervention on mental and physical health of older adults.

  Kazuhiro Harada, Kouhei Masumoto, Keiko Katagiri, Ai Fukuzawa, Michiko Touyama, Daichi Sonoda, Makoto Chogahara, Narihiko Kondo, Shuichi Okada

  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 effect of a multicomponent dual-task exercise on cortical thickness in older adults with cognitive decline: a randomized controlled trial.

  Seongryu Bae, Kenji Harada, Sangyoon Lee, Kazuhiro Harada, Keitaro Makino, Ippei Chiba, Hyuntae Park, Hiroyuki Shimada

  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.

• Psychological and Environmental Correlates of Moderate-to-Vigorous Physical Activity and Step Counts Among Older Adults With Cognitive Decline

  Kazuhiro Harada, Sangyoon Lee, Sungchul Lee, Seongryu Bae, Kenji Harada, Takao Suzuki, Hiroyuki Shimada

  Promoting physical activity (PA) among older adults with cognitive decline is important for maintaining and improving their health. Identifying psychological and environmental PA correlates in this population can help develop effective strategies for PA promotion. Since past findings with healthy older adults may not generalize to those with cognitive decline, this study offers data on how self-efficacy, self-regulation, and social-environmental factors were associated with PA among a group of older adults with cognitive decline. We report secondary analysis of baseline data from a randomized control study of 262 older participants ( M = 76.2 years) who showed a decline in global cognitive function as defined by Mini-Mental State Examination scores between 21 and 24. The participants’ PA was measured by an accelerometer, and participants completed questionnaires measuring self-efficacy, self-regulation, social support, social network, and demographic variables. In this study, we evaluated the participants' neighborhood environment with a geographic information system and found through stepwise multiple regression analyses that self-efficacy, gender, and age were associated with PA variables, while self-regulation and environmental factors were not. Thus, perceived self-efficacy was an important psychological correlate of PA in this group of older adults with cognitive decline. PA promotion interventions for this population should attend to self-efficacy, gender, and age.

• Perceived Food Environment Predicts Vegetable Intake According to Income: A Cross-Sectional Study

  Saki Nakamura, Takayo Inayama, Kazuhiro Harada, Takashi Arao

  Global health policies are promoting increased vegetable intake across all socioeconomic levels. However, the association between healthy vegetable intake and perception of the food environment has not been well investigated. Consequently, this study aimed to examine the association between vegetable intake and perceptions of neighborhood food environments. Participants were 3,137 Japanese adults (1,580 men, 1,557 women), aged 30 to 59 years, who completed an Internet-based survey. Self-report data were collected: vegetable intake, perceptions of food environment, household income, and demographic variables. We found that positive perceptions of the food environment (e.g., reasonable prices for foods and good social capital of food) predicted healthy vegetable intake in all household income groups. Therefore, supporters should take note of perceptions of the food environments—the findings suggest that the food environment can be altered via changing perceptions surrounding costs.

• Exercising Alone or Exercising With Others and Mental Health Among Middle-Aged and Older Adults: Longitudinal Analysis of Cross-Lagged and Simultaneous Effects

  Kazuhiro Harada, Kouhei Masumoto, Narihiko Kondo

  Background: Although the beneficial effects of physical activity and exercise on mental health are well known, the optimal conditions for them for benefitting mental health are still unclear. Engaging in exercise with others might have more desirable effects on mental health than engaging in exercise alone. This study examined the associations between exercising alone, exercising with others, and mental health among middle-aged and older adults. Methods: Baseline and 1-year follow-up surveys were conducted with 129 individuals. Time spent exercising alone or with others was measured using a 7-day diary survey. Total physical activity was objectively measured using an accelerometer. Mental well-being was assessed using the simplified Japanese version of the World Health Organization Five Well-Being Index, and mental distress was assessed using the Japanese version of the Kessler Distress Scale (K6). Results: Cross-lagged and simultaneous effects models revealed that exercising with others positively influenced mental well-being. Exercising alone and total physical activity did not significantly influence mental well-being. Neither total physical activity, exercising alone, nor exercising with others was significantly associated with mental distress. Conclusion: Engaging in exercise with others could be effective in improving mental well-being relative to engaging in exercise alone.

• Impact of sedentary time on chronic kidney disease and disability incidence in community-dwelling Japanese older adults: a 4-year prospective cohort study.

  Sungchul Lee, Sangyoon Lee, Seongryu Bae, Kazuhiro Harada, Songee Jung, Keitaro Makino, Hiroyuki Shimada

  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.

• The effect of a multicomponent intervention to promote community activity on cognitive function in older adults with mild cognitive impairment: a randomized controlled trial.

  Seongryu Bae, Sangyoon Lee, Sungchul Lee, Songee Jung, Keitaro Makino, Kazuhiro Harada, Kenji Harada, Yohei Shinkai, Ippei Chiba, Hiroyuki Shimada

  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.

• Relationship between chronic kidney disease without diabetes mellitus and components of frailty in community-dwelling Japanese older adults.

  Sungchul Lee, Sangyoon Lee, Seongryu Bae, Kazuhiro Harada, Songee Jung, Masakazu Imaoka, Hyuma Makizako, Takehiko Doi, Hiroyuki Shimada

  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.

  Seongryu Bae, Hiroyuki Shimada, Sangyoon Lee, Hyuma Makizako, Sungchul Lee, Kazuhiro Harada, Takehiko Doi, Kota Tsutsumimoto, Ryo Hotta, Sho Nakakubo, Hyuntae Park, Takao Suzuki

  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.

  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.

  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.

  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.

• Going outdoors and cognitive function among community-dwelling older adults: moderating role of physical function.

  Kazuhiro Harada, Sangyoon Lee, Hyuntae Park, Hiroyuki Shimada, Hyuma Makizako, Takehiko Doi, Daisuke Yoshida, Kota Tsutsumimoto, Yuya Anan, Kazuki Uemura, Takao Suzuki

  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.

  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.

  本研究の目的は下記の2点である。 目的1：高齢期の感情調整機能が社会的つながり（頼れる人の数，友人の数，サポートの有無など）に及ぼす影響を縦断データを用いて検討する。 目的2：高齢期の感情調整が社会的つながりの基盤である「他者への信頼」に及ぼす影響を生物学的要因（遺伝特性，ホルモン分泌量），心理的要因（記憶，実行機能，処理速度）をふまえた上で心理実験により明らかにする。 目的1を検討するために，本年度は約2000名を対象とした質問紙による縦断調査を実施した。2023年度はこれらデータを用いて，感情調整が社会的つながりを予測するのか検討をおこなう。 目的2については，他者への信頼にホルモン分泌が及ぼす影響を，高齢者および大学生各100名を対象とし検討した。ホルモンレベルと利他的行動の関係を検討するため、各年齢群について性別と性格をコントロール変数とした偏相関分析を実施した。若年成人群では、バソプレシンがボランティア頻度や臓器提供の意思と負の相関を示した。高齢者グループでは、バソプレシンとボランティア頻度の間に負の相関が見られた。同時に、オキシトシンは臓器提供の意欲と正の相関を示した。これらの結果は、バソプレシンとオキシトシンのホルモンレベルが利他的行動に関連することを示唆している。しかし、オキシトシンと利他的行動との間に関連が見られたのは高齢者のみであった。オキシトシンが利他的行動に及ぼす影響は年齢層によって異なり、年齢が上がるにつれてその影響は大きくなる可能性が示唆された。

  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。
