Falls in the institutionalized elderly in Japan

Abstract

Falls can be considered a vital factor in impeding successful aging in the elderly. The purpose of the study is to know rates of falls per year among the elderly, to observe the situations when falls occurred, and to clarify the association of falls with physical deterioration. The survey was carried out in 1 406 residents aged 65 and over of the Tokyo Metropolitan Home for the Elderly in 1982. The rate of subjects who fell more than once during a one-year period was 14.5%. Females had a higher rate than males. Sixty per cent of all the falls occurred indoors. As for the cause of the falls, extrinsic factors were accounted three times as much as intrinsic factors. Among injuries sustained by the falls, fracture was more frequent in females than in males. Length of time of standing on one leg was shorter for fallers than for non-fallers in both sexes. However, the differences were not significant when age was controlled. Fall is attributed not only to physical factors but also to environmental factors. Therefore, it should be encouraged to design an environment with devices.
