Treating for Depression in Pregnancy May Decrease Preterm Births emiliau/Fotolia

Depression and its effect on mothers and babies can begin long before delivery. One of the concerns about prescribing antidepressants during pregnancy is that they may lead to preterm labor or other health risks.

However, a recent study by researchers from Massachusetts General Hospital and Brigham and Women's Hospital, has shown that not taking antidepressants to treat depression may contribute to a similar health risk to the infants.

Of the 7,267 women screened for depression who had delivered at 20 weeks or later, 831 (11 percent) were found to have depression using the Edinburgh Postnatal Depression Scale.

The study results were controlled statistically for: maternal age, race, income, body mass index, tobacco use, lifetime diagnosis of major depression as well as anxiety, diabetes, hypertension and preeclampsia.

Researchers found that “depressive symptoms were associated with a 27 percent increased relative risk of preterm birth (less than 37 weeks of gestation), an 82 percent increased risk of very preterm birth (less than 32 weeks of gestation), and a 28 percent increased risk of having a baby small for gestational age,” reported the New York Times.

A secondary analysis was done on women who had taken antidepressants during their pregnancy. Out of the original group, 518 women (7 percent) were exposed to antidepressants. These women did not have a greater incidence of preterm labor or a small-for-gestational-age infant.

This group size was admittedly small to infer a link, according to the researchers. However, in view of the higher risk of premature births that occur in women with depression, further studies would help evaluate which women may benefit from taking antidepressants.
