Depression in childbearing women: when depression complicates pregnancy.

Prevalence studies show that one in five women experience an episode of major depressive disorder during their lifetime. It is important for health care providers to be aware of (1) the frequency of depression in this population; (2) signs, symptoms, and appropriate screening methods; and (3) health risks for the mother and growing fetus if depression is undetected or untreated. Because management of depressed pregnant women also includes care of a growing fetus, treatment may be complicated and primary care providers should consider a multidisciplinary approach, including an obstetrician, psychiatrist, and pediatrician, to provide optimal care.
