Recent study revealed that women who have diabetes during pregnancy have double risk of developing depression as compared to pregnant women without depression.  

Research team led by Katy Backes Kozhimannil of Harvard Medical School in Boston analyzed data collected from more than 11,000 pregnant women enrolled in New Jersey's Medicaid program from July 2004 to September 2006. The women were followed for six months before to one year after the women gave birth.

Data analysis showed that 15.2 percent of study subjects with diabetes developed depression during or after their pregnancy as compared to 8.2 percent study subjects without diabetes.  

Kozhimannil said: "Those with diabetes have nearly twice the risk of depression during pregnancy and post-partum"

Study showed that women who'd never been depressed before appeared to be at risk, too. She said that one in 10 women who had no indication of prior depression received a diagnosis of depression within a year following delivery.

She added: "Postpartum depression is a very serious illness that affects between 10 and 12 percent of mothers every year. It may have long-term negative impacts on the women it affects, but also on their children and families."
