[Epidemiology of falls among community-dwelling elderly people].

The purpose of the present study was to report the prevalence and circumstances of falls among community-dwelling elderly people in order to contribute to prevention of falls in the community. The subjects were 2,774 elderly people who participated in health examinations conducted by Tokoname-shi, Aichi Prefecture in 2002. The variables investigated in the present study were demography and history of falls in the past one-year. Circumstances of falls, e.g. time, location, activities associated with falls, cause of falls and degree of injury due to falls were asked when the subjects experienced a fall. The prevalence of falls among 2,774 subjects was 13.7%. It was significantly higher among women (17.2%) than men (8.3%, chi 2 = 48.1, p < 0.001). Prevalence increased as subjects get older. Circumstances of falls were assessed in 655 subjects. The distribution of time, location, activity associated with falls, cause and injury due to falls corresponded with previous fall studies among community dwelling elderly people. The incidence of falls was extremely high during the daytime and outdoors. Falls occurred most frequently while walking. The majority of falls were due to extrinsic factors. About 10% of all falls caused fracture.
