A study by the University of Iowa published in the journal Social Psychiatry and Psychiatric Epidemiology reports that low-income women in Iowa are much more likely to suffer from postpartum depression than wealthier women.
University of Iowa psychologist Lisa Segre and colleagues studied 4,332 new mothers from four Iowa counties. The researchers collected sociodemographic data and the participants completed the Inventory to Diagnose Depression in the late 1990s. The mothers had given birth an average of 4.6 months before the survey.
