Obesity Linked to Postpartum Depression Risk

Obesity Linked to Postpartum Depression Risk

Previous studies have linked postpartum depression (PPD) to numerous risk factors, including depression during pregnancy, a history of depression prior to pregnancy, as well as marital problems, recent stressful events, and inadequate social supports.

Research conducted at the University of Utah in Salt Lake City now suggests that obesity may place women at increased risk of postpartum depression, as presented in a poster at the annual meeting for the Society of Maternal-Fetal Medicine. In their study of 1282 women who gave birth to singleton infants, the risk of screening positive on the Edinburgh Postnatal Depression Screen 8 weeks after delivery increased dramatically for women with a pregnancy body mass index (BMI) greater than 35. They also noted that women at the extremes of body mass index and those with greater weight gain during pregnancy were at increased risk for postpartum depression.

BMI

Positive for PPD

Underweight

Under 18.5

18.7%

Normal Weight

18.5-24.9

12.7%

Overweight

15-19.9

15.9%

Class I Obesity

30-34.9

17.6%

Class II Obesity

35-39.9

28%

Class III Obesity

40 or greater

29.4%

Increased BMI was a risk factor even after controlling for maternal age, race, number of children, education, and other stressors such as financial stressors and partner-related stressors. It is important to note that there were far fewer women in the class II obesity and class III obesity groups than in the other groups.

This is first study to use a validated screening tool to look at the relationship between maternal BMI and postpartum depression. As more research in this field develops, it is our hope that we will be better able to identify patients at risk for postpartum depression in the future.
