Previous studies suggested that mobility is a target for preventing decline in the ability to perform basic activities of daily living (ADLs) in elderly people. Despite the fact that mobility as well as ADL ability decline with aging, those studies have focused only on the relationships between initial level of mobility and subsequent decline of ADL ability. The purpose of this study was to clarify the longitudinal relationships between ADL ability and mobility in elderly people. ADL ability and mobility were assessed in 422 non-institutionalized Japanese elderly residents aged 75 years or older by the Katz index and the Rivermead mobility index at baseline and 18-month follow-up. Longitudinal relationships were examined using a cross-lagged structural equation model and latent growth modeling. The results indicated that mobility affects future ADL ability, whereas ADL ability has almost no feedback effect on future mobility, and that only change in mobility affects the decline in ADL ability. These findings suggest that maintenance of the level of mobility will contribute to maintenance of ADL ability in elderly people.
