Abstract
The objective of this study was to assess the longitudinal impact of joint impairment on overall disability and crossing domain-specific thresholds for physical activity, mobility, dexterity, instrumental activities of daily living (IADL), and activities of daily living (ADL) that are associated with use of long-term care. This 4-year longitudinal study observed 484 persons older than age 60. Logistic regression assessed the contribution of demographics, psychological mediators, lowers- and upper- extremity joint impairment, and comorbities to increased domain-specific self-reported disability above a threshold associated with use of long-term care. Lower- extremity joint impairment and age predicted crossing thresholds by year 4 in physical activity, mobility, IADL, and ADL disability that were associated with use of long-term care. Lower-extremity joint impairment is a strong risk factor for future disability that is associated with use of long- term care.
