Effect of Maternal Depressive Symptoms on Prenatal Care Utilization and Milestones [ID: 1376259

Abstract

INTRODUCTION: Depression is a common complication of pregnancy, but research is limited regarding its effect antepartum. This study assessed the relationship between maternal depressive symptoms and prenatal care utilization. METHODS: This retrospective cohort includes pregnant women who completed first- or second-trimester depression screening using the Edinburgh Postnatal Depression Scale (EPDS) between 2020 and 2021. Patient and pregnancy-related characteristics were compared between women who screened positive versus negative for depression. Multivariate logistic regression models were used to estimate odds of completing prenatal care milestones. The IRB approved a consent waiver. RESULTS: Of 718 women who completed the EPDS in early pregnancy, 85 (12%) screened positive for depression. A greater proportion of these women were younger (P=.034), unpartnered (P=.005), publicly insured (P=.013), had a history of substance use (P<.0001) or prior psychiatric diagnosis (P<.0001), and started prenatal care later (P=.002) than those who screened negative. Although there were no significant differences in total routine prenatal care visits (P=.123), the adjusted odds of completing third-trimester milestones including glucose tolerance testing (odds ratio [OR] [95% CI] 0.596 [0.364–0.975]) and group B streptococcus testing (OR [95% CI] 0.559 [0.330–0.947]) were lower among women who screened positive for depression. In addition, higher EPDS scores were positively correlated with number of labor and delivery triage visits (r=0.103, P=.006). CONCLUSION: Women who screen positive for depression during pregnancy are a socially vulnerable group at risk of starting prenatal care late, missing major milestones, and overusing nonroutine medical services. Early mental health screening and intervention in pregnancy may help improve prenatal outcomes.
