Age group differences in depressive symptoms among older adults with functional impairments.

This study used data from the 2000 interview wave of the Health and Retirement Study to examine age group differences in the likelihood of self-reported depressive symptomatology among a nationally representative sample of 3,035 adults age 55 years or older who had at least one activities of daily living (ADL) or instrumental activities of daily living (IADL) limitation. Depression was defined as scoring three points or higher on the eight-point Center for Epidemiological Studies Depression Scale. The results show that respondents age 75 years or older with one ADL/IADL impairment or more were significantly less likely to be depressed than were those between ages 55 and 64 with the same degree of functional impairment. It is recommended that doctors, social workers, and other health care and social services providers pay special attention to younger old adults with health problems and functional limitations because they have a greater risk of being depressed.
