Objective: This study aimed to measure the physical activity (exercise and non-exercise) of community-dwelling elderly Japanese individuals and to investigate the relationships between physical activity and daily life behaviors.

Methods: Community-dwelling elderly Japanese individuals who resided in town A, city B, Gunma Prefecture, Japan, and were not certified as requiring long-term care were included in this study. Physical activity in 1 week was measured using a triaxial accelerometer. A self-administered questionnaire was applied to assess daily life behaviors. Hierarchical multiple regression analysis was used to examine the factors affecting physical activity.

Results: A total of 107 elderly Japanese (46 men and 61 women) individuals were included. The mean amount of physical activity in men was 37.9 Metabolic equivalents (METs)*h/wk, whereas that in women was 33.8 METs*h/wk. The proportion of exercise to physical activity for men and women was 43.2% and 26.0%, respectively. Men and women took an average of 47,393.7 and 35,305.6 steps/wk, respectively. Step counts and the presence or absence of plant cultivation were the factors associated with the amount of physical activity. The exercise component of physical activity was associated with step count, whereas the non-exercise component was associated with step count, plant cultivation, and frequent outings.

Conclusion: Among community-dwelling elderly Japanese individuals, physical activity levels appear to be affected by step count and the presence or absence of certain factors, such as plant cultivation and frequent outings.
