Background: The use of mobile apps has promoted physical activity levels. Recently, with an increasing number of older adults accessing the internet, app-based interventions may be feasible in older populations. Peer support-based interventions have become a common method for promoting health-related behavior change. To our knowledge, the feasibility of using digital peer support apps (DPSAs) to increase physical activity among older adults and its impact on physical activity and physical function have not been investigated. Objective: This study aims to assess the feasibility of using DPSAs in older adults and to assess changes in physical activity and physical function in DPSA users. Methods: We conducted a nonrandomized controlled trial of older adults aged ≥65 years. We recruited participants for 2 distinct 12-week programs designed to increase physical activity. Participants could choose between an intervention group (app program and exercise instruction) or a control group (exercise instruction only). DPSA creates a group chat for up to 5 people with a common goal, and participants anonymously post to each other in the group. Once a day, participants posted a set of their step counts, photos, and comments on a group chat box. The intervention group used the DPSA after receiving 2 face-to-face lectures on its use. The participants were characterized using questionnaires, accelerometers, and physical function assessments. The feasibility of the DPSA was assessed using retention and adherence rates. Physical activity was assessed using accelerometers to measure the daily step count, light intensity physical activity, moderate to vigorous intensity physical activity (MVPA), and sedentary behavior. Physical function was assessed using grip strength and the 30-second chair-stand test. Results: The participants in the intervention group were more frequent users of apps, were more familiar with information and communication technology, and had a higher baseline physical activity level. The retention and adherence rates for the DPSA intervention were 88% (36/41) and 87.7%, respectively, indicating good feasibility. Participants in the intervention group increased their step count by at least 1000 steps and their MVPA by at least 10 minutes using the DPSA. There was a significant difference in the interaction between groups and intervention time points in the daily step count and MVPA (step count, P=.04; duration of MVPA, P=.02). The DPSA increased physical activity, especially in older adults with low baseline physical activity levels. Conclusions: The feasibility of DPSA was found to be good, with the intervention group showing increases in daily steps and MVPA. The effects of DPSA on step count, physical activity, and physical function in older adults with low baseline physical activity should be investigated using randomized controlled trials.

Aim: Some studies have reported a higher incidence of falls during winter with similar proportions of indoor and outdoor falls. We investigated the relationship between indoor temperature during winter and falls at home in the past year among community-dwelling older adults.Methods: This cross-sectional study enrolled 964 individuals of ≥65 years of age in Japan. Participants answered questions about falls (including trips) at home within the past year, and the living room temperature was measured for 2 weeks during winter. Participants were divided into those living in cold (mean temperature near the floor <12°C), slightly cold (12-17.9°C), and warm (≥18°C) houses. The association between indoor temperature (cold vs. slightly cold vs. warm houses) and falls at home in the past year was examined using a logistic regression analysis adjusted for potential confounding factors.Results: Valid data were obtained from 907 participants (mean age: 72.0±6.3 years), of whom 265,553, and 89 lived in cold, slightly cold, and warm houses, respectively. In the past year, falls occurred once in 325 (35.8%) participants and multiple times in 148 (16.3%) participants. In warm houses, the odds ratio of falling once and multiple times in the past year was 0.49 (p=0.032) and 0.34 (p=0.035), respectively, in comparison to cold houses.Conclusions: Living in cold houses may be associated with an increased risk of falling at home among older adults. Maintaining an appropriate indoor thermal environment during winter may reduce the risk of falling among individuals who spend most of their time at home.

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.

Sarcopenia is one of the primary risk factors for various adverse health events in later life. However, its pathophysiology in the very old population remains unclear. Hence, this study aimed to examine whether plasma free amino acids (PFAAs) correlate with major sarcopenic phenotypes (i.e., muscle mass, muscle strength, and physical performance) in community-dwelling adults aged 85–89 years living in Japan. Cross-sectional data from the Kawasaki Aging Well-being Project were used. We included 133 adults aged 85–89 years. In this study, fasting blood was collected to measure 20 plasma PFAAs. Measures for the three major sarcopenic phenotypes included appendicular lean mass assessed by multifrequency bioimpedance, isometric handgrip strength, and gait speed from a 5 m walk at a usual pace. Furthermore, we used phenotype–specific elastic net regression models adjusted for age centered at 85 years, sex, body mass index, education level, smoking status, and drinking habit to identify significant PFAAs for each sarcopenic phenotype. Higher histidine and lower alanine levels were associated with poor gait speed, but no PFAAs correlated with muscle strength or mass. In conclusion, PFAAs such as plasma histidine and alanine are novel blood biomarkers associated with physical performance in community-dwelling adults aged 85 years or older.

目的:断熱改修が冬季の住宅内の座位行動と身体活動に及ぼす影響を検討した。方法:断熱改修に意欲的な成人を募集し,冬季2週間のベースライン調査(改修前)と,その1～4年後の同時期に追跡調査(改修後)を行った。住宅内の座位時間と低強度以上の身体活動量(light-to-vigorous physical activity;LVPA)は,加速度計と外出記録から評価した。断熱改修を行った介入群と断念した対照群に対象者を分け,住宅内の座位時間とLVPAの変化との関連を線形混合モデルで検討した。また,脱衣所室温変化量[低下(-1℃未満),変化なし(-1℃以上+1℃未満),上昇小(+1℃以上+5℃未満),上昇大(+5℃以上)]を説明変数に加えた解析も実施した。結果:1,751名(介入群1,640名,対照群111名)を解析対象とした。脱衣所室温は介入群で有意に上昇したが,群間で調査期間のずれが生じたことなどにより,対照群の室温も外気温の上昇に伴い上昇していた。多変量解析の結果,断熱改修と住宅内の座位時間・LVPAの変化に有意な関連は認められなかった。ただし,脱衣所室温変化量は有意に関連していた。室温が変化しなかった場合に比べて,5℃以上改善した場合は,座位時間が減少し,LVPAは増加したが,室温が低下した場合には,座位時間が増加し,LVPAは減少した。結論:断熱改修は住宅内の座位時間とLVPAの変化に関連していなかった。ただし,脱衣所等の室温改善は,住宅内の座位行動を抑制し,LVPAを増加させる可能性が示唆された。今後も検証が必要である。(著者抄録)

Objectives: As the world's population is ageing, improving the physical performance of the older population is becoming important. Although diets are fundamental to maintaining and improving physical performance, few studies have addressed the role of these factors in adults aged ≥85 years, and none have been conducted in Asia. This study aimed to determine the dietary patterns and examine their relationship with physical performance in this population. Design: This cross-sectional study (Kawasaki Aging and Wellbeing Project) estimated food consumption using a brief-type self-administered diet history questionnaire. The results were adjusted for energy after aggregating into 33 groups, excluding possible over- or underestimation. Principal component analysis was used to identify dietary patterns, and outcomes included hand grip strength, timed up-and-go test, and usual walking speed. Setting: This study was set throughout several hospitals in Kawasaki city. Participants: In total, 1,026 community-dwelling older adults (85-89 years) were enrolled. Results: Data of 1,000 participants (median age: 86.9 years, men: 49.9 %) were included in the analysis. Three major dietary patterns (DP1: various foods, DP2: red meats and coffee, DP3: bread and processed meats) were identified. The results of multiple regression analysis showed that the score of DP2 was negatively associated with hand grip strength (B, 95% confidence interval: -0.35, -0.64 to -0.06). Conclusions: This study suggests a negative association between hand grip strength and dietary patterns characterised by red meats and coffee in older adults aged ≥85 years in Japan.
