    This research aimed to cluster the sedentary behavior of the elderly requiring home-care by using sedentary behavior bout, which means continuous sedentary behavior, and the characteristics of functioning by these clusters. A cross-sectional survey was conducted on the physical activity and functioning of the elderly who require care and use home-visit rehabilitation. Hierarchical cluster analysis was conducted based on the total time of sedentary behavior and three types of the sedentary bout: less than 30 minutes, 30 to 59 minutes, and more than 60 minutes. The results showed that there were three groups: the prolonged sedentary group, which had more sedentary time in the bout of more than 60 minutes and less in the bout of less than 30 minutes; the short sedentary group, which contrasted with the prolonged sedentary group; and the intermediate sedentary group. The individuals in the prolonged sedentary group showed lower gait ability, applied ADL, and lower tendency in ADL than the other groups. On the other hand, there were no significant differences in functioning between individuals in the short and intermediate sedentary groups. The sedentary bouts can categorize the characteristics of sedentary behavior of the elderly requiring care, and some elderly showed sedentary behavior that is hard to explain based only on their functioning.

    Objective: The purpose of this study was to determine the relationship between the measured mass of the calcaneus bone and the number of stairs used by community-dwelling older adults. Methods: Data obtained from 169 older adults who participated in a community-based health-check survey (Tarumizu Study 2018) were analyzed. Bone mass was measured using the speed of sound of the calcaneal bone and the obtained values were considered to be low when the percentage of the %YAM of the SOS was ≤ 70%. The frequency of stair usage was classified into two groups: 0 and 1 or more times per day at home, and three sub-groups comprising of: 0–2, 3–7, and 8 or more times per week outside home. Results: The results of logistic regression analysis, in which the dependent variable was the presence or absence of bone loss, and the independent variable was the number of stairs used, showed no significant association with the number of stairs used at home. The number of times the stairs were used outside home was set at 0–2 times as a reference, and bone loss was significantly reduced by 8 times or more (odds ratio 0.32, 95% confidence interval 0.11 –0.97, p = 0.045, covariates: age, gender, ASMI, grip strength, walking speed). Conclusion: It was suggested that the frequent use of stairs outside the home may aid in suppressing bone loss. It could be concluded that the use of stairs in activities including going out may affect bone mass as the frequency of stair usage in the house is not relevant.
