Abstract
Data from the Longitudinal Study of Aging (LSOA) were analyzed to estimate the subsequent risk of institutionalization associated with a report of one or more falls, and to determine if the association is affected by controlling for demographic traits, chronic conditions, and disabilities present at baseline. Risk was estimated at two time points, 2 years and 4years after baseline interview. A report of multiple falls at baseline was associated with an increased risk of institutionalization at both 2 years (odds ratio [OR] 3.1; 1.9-5.3) and 4 years (OR 2.6; 1.64.4) of follow-up. The risk was decreased but remained significant in a model controlling for age, sex, marital status, and selected chronic conditions associated with both report of falls and institutionalization. However, multiple falls were not significantly associated with institutionalization when measures of disability (number of difficulties with activities of daily living) were added to the model. These analyses suggest that multiple falls should be regarded as an important sentinel event to alert caregivers to the presence of underlying disease and disability that may require intervention.
