Abstract

Objective

The purpose of this study was to clarify the relationships among fall risk, physical activity habits, and ADL capability in a community-dwelling Japanese elderly population.

Methods

The subjects were 1,407 Japanese aged 65 or older (604 males, 803 females). Fall risk was evaluated using the Falling Assessment Chart of Suzuki et al. (2003). Physical activity habits such as the frequency of leaving the house, the use of transportation, the frequency of physical exercise, and interests were evaluated. ADL capability was evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence.

Results

Approximately 25% of the subjects had a high fall risk (score of 5 or more). Fall risk increased with age and ADL capability decreased with age. The group with a low fall risk (score<5) had a significantly higher ADL capability than the group with a high fall risk (score≥5). From results of two-way ANCOVA (gender×physical activity habits) with age as the covariate, the fall risk of people who regularly go on leaving the house, exercise, and have interests tended to be low. Further more, the relationships between the scores and physical activity habits were examined by two-way ANCOVA with age and ADL capability as the covariates. There were significant differences in the frequency of leaving the house, and elderly persons who leaved regularly the house, had a low fall risk.

Conclusions

This study showed that fall risk is closely related to ADL capability, and that the frequency of leaving the house is very important for reducing fall risk.
