The aim of this study was to determine neonatal outcomes among women who had depressive and anxiety disorders during the second trimester of pregnancy in a population-based sample. Participants were 1,465 women and their neonates born at two obstetric clinics in Sweden. The inclusion period for the women was October 2, 2000-October 1, 2001. The Primary Care Evaluation of Mental Disorders (PRIME-MD) classification system was used to evaluate mental disorders in the second trimester of pregnancy. For assessment of demographic characteristics, birth statistics, and birth-related complications, the medical records of the included women and their offspring were reviewed after delivery. The study results revealed no differences in neonatal outcome between women with antenatal depressive disorders and/or anxiety disorders and healthy subjects. The authors conclude that neonatal outcome did not deteriorate despite the women's impaired mental health during pregnancy.
