Racial Differences Seen for Depression Treatment

Second study suggests generalized anxiety disorder not best classified as depressive disease

WEDNESDAY, Jan. 6 (HealthDay News) -- There are racial disparities in the uptake of treatments for major depression in the United States, according to a study in the January issue of the Archives of General Psychiatry, while a second study found that generalized anxiety disorder is a heterogeneous disease more closely related to other anxiety disorders rather than depressive disorders.

Hector M. González, Ph.D., of Wayne State University in Detroit, and colleagues conducted a study of 15,762 people across the United States, and found that usage rates for depression therapies were lowest among Mexican-Americans and African-Americans with major depression, regardless of the extent of need for depression-related care.

Katja Beesdo, Ph.D., of the Technische Universitaet Dresden in Germany, and colleagues conducted a 10-year family study of 3,021 people aged 14 to 24 years at baseline and found that generalized anxiety disorder symptoms were more closely related to other anxiety disorders rather than to depression.

"Anxiety and depressive disorders appear to be remarkably different with regard to risk constellations and temporal longitudinal patterns. Generalized anxiety disorder appears to clearly differ from depression," Beesdo and colleagues write. "Although more work is needed on the unique etiological pathways for generalized anxiety disorder, it seems premature, at the least, to classify generalized anxiety disorder with the depressive disorders."

Authors of the second study reported financial relationships with the pharmaceutical industry.
