Comparison of two different treatments in depressed pregnant women: fetal growth characteristics and neonatal outcomes.

Background In this pilot study, the effects of selective serotonin reuptake inhibitors (SSRIs) and psychological intervention on fetal growth characteristics and neonatal outcomes were evaluated in two different groups of women affected by prenatal depression. Methods Forty-seven pregnant women diagnosed with major depression were divided into two different treatment groups according to the severity of their depression. The first group was treated with a combination of pharmacotherapy and psychological support. The second group (milder depression) was treated with psychological support only. The control group (CG) was made up of 26 healthy pregnant women. All of the patients and controls were assessed by means of a structured clinical interview and different self-reported questionnaires. Fetal ultrasonography assessments were performed in the second and third trimesters. Neonatal outcomes were evaluated at delivery. Results The infants of both treatment groups showed significant alterations in fetal biometry and a higher rate of low birth weight (LBW) with respect to controls. The infants of the patients treated with psychological support showed only a significantly higher rate of head circumference, <10th percentile with respect to controls. No significant difference was found between the two patient groups when fetal growth characteristics and neonatal outcomes were taken into account. Conclusion The data obtained from this study shed light on the effects of pharmacological and psychological treatment of prenatal depression on fetal growth.
