Depression is the leading cause of disease-related disability among women in the world. In particular, women during their reproductive years are at high risk for major depression (MDD) (Robins et al, 1991). Perinatal depression, defined as depressive episodes that occur either during pregnancy or within the first 6 months postpartum, can have devastating consequences for both the woman experiencing it as well for her children and family (Marmorstein et al, 2004; Flynn et al, 2004).
