Mental disorders during the perinatal period: Results from a nationally representative study

This study examined mental health profiles of pregnant and postpartum females, with and without perinatal complications, compared to non-perinatal females of childbearing age. We analyzed nationally representative data from the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions (N = 36,309; 51.9% female). A validated semi-structured interview assessed past-year DSM-5 mental disorders. Multivariable regressions examined associations between perinatal status and mental disorders, controlling for sociodemographic characteristics. Using females who were not pregnant in the past year as a reference group, those who were postpartum with complications during pregnancy or delivery had increased odds of any past-year mental disorder (58.7% vs. 46.8%; AOR = 1.56), any depressive/bipolar disorder (26.4% vs. 18.8%; AOR = 1.57), and posttraumatic stress disorder (14.0% vs. 7.3%; AOR = 1.99). In contrast, those who were postpartum without complications did not have increased odds of these disorders. Those who were pregnant without pregnancy complications had reduced odds of any past-year mental disorder (33.7% vs. 46.8%; AOR = 0.55) and any depressive/bipolar disorder (11.7% vs. 18.8%; AOR = 0.60). All perinatal groups had reduced odds of any substance use disorder compared to those who were not pregnant in the past year (18.9–25.7% vs. 29.8% AORs: 0.49–0.78), except those who were postpartum with pregnancy or delivery complications (28.8%). Results highlight the importance of mental health screening among perinatal females, particularly those who are postpartum and experience perinatal complications. Findings may inform the development of targeted interventions for this subpopulation.
