title: Contribution of falling and being homebound status to subsequent functional changes among the Japanese elderly living in a community.
abstract: Using the data from the community-based longitudinal study of the elderly persons aged 65 or older, this study examined relationships between the occurrence of falls varied by their activity level and subsequent functional decline over time. Of the 705 respondents at baseline, 662 and 632 subjects were assessed at first and second follow-ups. Falling and homebound status at baseline and health function (self-rated general health, activities of daily living (ADLs), instrumental activities of daily living (IADLs), intellectual activity, and social role) at baseline and follow-ups were assessed, and changes in each health function were compared among four groups defined by baseline falling/homebound status. Baseline falling/homebound status was significantly associated with subsequent decline in ADLs over 1 year, and in ADLs, IADLs, intellectual activity, and social role over 2 years. Being homebound might act as a stronger risk factor for ADLs disabilities rather than the occurrence of falls. Moreover, the homebound elderly with no experience of falls was at the greatest risk of the decline of social role. We consider that prevention program and home-based care for homebound elderly should be provided in the community.
