Prenatal antidepressants linked to preterm births

Antidepressant drug use during pregnancy, but not depression itself, is associated with an increased risk of preterm birth and lower fetal age at delivery, according to results of a study published in the American Journal of Psychiatry.

"Depressive symptoms are not uncommon during pregnancy, and...symptoms may occur more frequently during pregnancy than in the postpartum period," write Dr. Rita Suri and colleagues from the University of California, Los Angeles. Depression during pregnancy and just after delivery "has been associated with low maternal weight gain, increased frequency of cigarette, alcohol, and substance use, and ambivalence about the pregnancy."

To further investigate, the researchers examined the effects of maternal depression and antidepressant drug use on fetal age and risk of preterm birth in a study of 90 pregnant women.
