Unintentional Weight Loss Predicts Decline in Activities of Daily Living Function and Life-Space Mobility Over 4 Years Among Community-Dwelling Older Adults

摘要

Background. The relationship between body mass index (BMI), weight loss, and changes in activities of daily living (ADL) function and mobility in older adults is not clear. We sought to study the relationship between BMI and weight loss on the rate of decline in ADL function and life-space mobility over a 4-year period among older African Americans and whites.
