Depressed Women May Have Premature Babies

A study done in England on depressed pregnant women showed the severely depressed women who were not taking medications had premature labor.

That depression produces stress hormones is exemplified by this study. Dr. O'Keane, a perinatal psychiatrist at the King's College in London measured corticotrophin releasing hormone (CRF) in 25 depressed pregnant women who were not on any antidepressant medications and 35 pregnant women who had no depression.

Levels of CRF and cortisol, hormones related to stress and also produced  by the placenta in pregnancy were found to be higher in women with depression.

While none of the mothers that were not depressed had premature deliveries, on the average, the depressed mothers had their babies 2 days earlier and 3 of them had premature deliveries.

During the follow up visit, the babies whose mothers had depression had high levels of cortisol in their saliva, a sign that their mothers' stress had effect on them..

The study involved a few patients. More studies are needed to elucidate the findings of this interesting small study. The take home message is that depressed pregnant patients' stress may have effect on their unborn babies. The effect may even continue after delivery. Hence pregnant women who are depressed should be treated with antidepressants despite the fear that some of the antidepressants may have effect on the newborn babies.
