Having an abortion does not increase the risk of mental health problems, but having a baby does, one of the largest studies to compare the aftermath of both decisions suggests. The research by Danish scientists further debunks the notion that terminating a pregnancy can trigger mental illness and shows postpartum depression to be much more of a factor. The Danish study included 365,550 teenagers and women who had an abortion or first-time delivery between 1995 and 2007. None had a history of psychiatric problems that required hospitalization. While first-time mothers had a lower rate of mental problems overall, the proportion of those seeking help after giving birth was dramatically higher. About 7 per 1,000 women got mental health help within a year of giving birth compared with 4 per 1,000 women pre-delivery. The most common problems among women in both the abortion and the delivery groups were debilitating anxiety, severe stress and depression.
