New Data: Perinatal MDD Peaks 2 Weeks After Birth
A recent study found that major depressive disorder (MDD) affects about 6% of women during pregnancy and peaks at 9.8% in the first two weeks postpartum. The study analyzed data from over 2 million women and highlighted that common symptom scales often overestimate MDD prevalence. Researchers emphasize the need for early identification and intervention strategies during this critical period.
- ▪Approximately 6% of women experience MDD during pregnancy, with prevalence peaking at 9.8% in the first two weeks after birth.
- ▪The study included data from over 2 million women across 90 countries and revealed that commonly used symptom scales overestimated MDD prevalence by 71%-122%.
- ▪The highest rates of MDD were observed in southern sub-Saharan Africa and South Asia, while the lowest rates were found in the high-income Asia-Pacific region.
