In a study that included nearly 30,000 women from Nordic countries who had filled a selective serotonin reuptake inhibitor (SSRI) prescription during pregnancy, researchers found no significant association between use of these medications during pregnancy and risk of stillbirth, neonatal death, or postneonatal death, after accounting for factors including maternal psychiatric disease, according to a study in the January 2 issue of JAMA.
"Depression during pregnancy is common with prevalences ranging between 7 percent and 19 percent in economically developed countries. Maternal depression is associated with poorer pregnancy outcomes, including increased risk of preterm delivery, which in turn may cause neonatal morbidity and mortality," according to background information in the article. "Use of selective serotonin reuptake inhibitors during pregnancy has been associated with congenital anomalies, neonatal withdrawal syndrome, and persistent pulmonary hypertension of the newborn. However, the risk of stillbirth and infant mortality when accounting for previous maternal psychiatric disease remains unknown."
Olof Stephansson, M.D., Ph.D., of the Karolinska Institutet, Stockholm, Sweden and colleagues conducted a study to examine whether SSRI exposure during pregnancy was associated with increased risks of stillbirth, neonatal death, and postneonatal death. The study included women with single births from all Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden) at different periods from 1996 through 2007. The researchers obtained information on maternal use of SSRIs from prescription registries; maternal characteristics, pregnancy, and neonatal outcomes were obtained from patient and medical birth registries. The authors estimated relative risks of stillbirth, neonatal death, and postneonatal death associated with SSRI use during pregnancy taking into account maternal characteristics and previous psychiatric hospitalization.
