Abstract
  • Background: Depression is a disease of great public health concern as it is responsible for a significant amount of disability and morbidity, and millions of Americans are depressed in any given year. Antepartum and postpartum depression confer health risks for the mother and her family. Research has indicated that physically active individuals may be less likely to experience depression, however, few studies have used pregnancy and postpartum samples. Methods: Data from the third and postpartum phases of the Pregnancy, Infection, and Nutrition (PIN) Study were used to determine the association between moderate-to-vigorous physical activity (MVPA) and depressive symptoms among pregnant and postpartum women. The PIN3 Study was a prospective cohort of 2006 pregnant women in North Carolina enrolled between January 2001 and June 2005. The PIN Postpartum Study followed a subset of the PIN3 women with in-home visits at 3 and 12 months postpartum. Physical activity recall was assessed by telephone at 17-22 and 27-30 weeks' gestation of pregnancy and at 3 months postpartum. Self-reported depressive symptoms were assessed by the Center for Epidemiologic Studies-Depression Scale at <20 and 24-29 weeks' gestation, while postpartum depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale at both home visits. Results: Active women with <=2.67 hours/week of total MVPA at 17-22 weeks' gestation had almost half the odds of having high depressive symptoms at 24-29 weeks' gestation as compared to women with no MVPA. However, total MVPA at 3 months postpartum was associated with a doubling of the odds of elevated depressive symptoms at 12 months postpartum. Adult and child care and indoor household MVPA were associated with increased odds of elevated depressive symptoms in both pregnancy and postpartum. No benefit from recreational activity on depressive symptoms was found at any time point. No significant associations were found between MVPA and depressive symptoms when examining the association between MVPA during pregnancy and 3-month depressive symptoms. Conclusion: Associations between physical activity and depressive symptoms differ by domain of MVPA. Future studies with higher statistical power should explore potential differences by domain of physical activity.
