Few studies have examined whether rates of psychiatric diagnosis differ among elderly members of racial groups, an issue that has important implications for treatment planning. In a study of a large group of elderly African-American, Caucasian, and Hispanic patients in the Veterans Affairs health care system, Helen C. Kales, M.D., and her colleagues found significantly lower rates of mood disorders among elderly African-American patients than among elderly Caucasian and Hispanic patients. In every analysis, the rate of mood disorders among African-American patients was less than half the rate among Caucasians, a finding that clearly merits further study, the authors say (see page 795).
