Prepregnancy Depressive Mood is a Risk Factor for Preterm Birth
There have been multiple studies suggesting that depression during pregnancy increases the risk for preterm labor. Most studies do not attribute this increase in risk to antidepressant exposure, but to the effects of the depression itself. The mechanism is believed to be related to increased levels of corticotropin releasing hormone (CRH) which is triggered by stress. Elevated levels of CRH have been shown to be a predictor of preterm birth.
