Racial differences on association of depressive symptoms with combined basic and instrumental activities of daily living.
Depressive symptoms are predictive of multiple degenerative diseases in older age adults. However, the association of depressive symptoms with onset and progression of disability have not been studied. ⋯ Depressive symptoms increased the risk of onset of disability in blacks and whites. This risk tended to increase over time only among whites. A similar race-specific pattern was observed for time-dependent changes due to depressive symptoms in the rate of progression in disability after onset.
