Depression in a family practice elderly population.

This study addresses several major methodologic issues in the assessment of depressive illness among the elderly family practice living in the community. These include the selection of screening locale, the definition of depression in the elderly, and the evaluation of age trends within this group. The family physician's office is viewed as the optimal screening locale; this facility serves as the chief link between the elderly patient and the community health care system, for psychologic as well as physical complaints. In the definition of depression, a type of depressive illness particularly affecting the elderly may be distinguished from a syndrome more characteristic of depression in the population at large. Emphasis is laid on viewing aging as an evolving process rather than as a steady state. A pilot study of 166 chronically ill family practice patients living in the community was conducted. A large proportion of them, all without previously diagnosed psychiatric impairment, had elevated depression scores according to the Zung Depression Status Inventory. Distinct symptom clusters characteristic of depression in the aged were identified. The data also suggested a systematic age trend, with different peaks of depression for men and women within the elderly age range.
