Age and sex differences in somatic complaints associated with depression.

Following the procedure used by Zemore and Eames (1979) with the Beck Depression Inventory, the 20 items of the Zung Self-Rating Depression Scale were categorized as either somatic or psychological symptoms of depression. Scores of 179 college students and 462 community-dwelling older adults revealed significant, though small, age differences in somatic complaints. Somatic complaints were especially prominent in older women. Age differences in psychological symptoms of depression were not significant. Diagnosis of depression in later life, especially in women, may be confounded by the use of physical symptoms of depression that are comparable to physical changes that accompany the aging process.
