Enhanced Prenatal Care Models and Postpartum Depression: The EMBRACE Randomized Clinical Trial.

Area of Science:

• Perinatal Health
• Mental Health Disparities
• Social Determinants of Health

Background:

• Racial, ethnic, and income disparities contribute to perinatal depression prevalence and treatment gaps.
• Effective interventions addressing social determinants of health are crucial for maternal mental well-being.

Purpose of the Study:

• To compare the effectiveness of enhanced group prenatal care (eGPC) versus enhanced individual prenatal care (eIPC) in reducing perinatal depressive symptoms.
• To investigate if eGPC offers superior outcomes compared to eIPC for maternal mental health.

Main Methods:

• A randomized clinical trial involving 674 low-income, pregnant individuals across 10 clinics in California's San Joaquin Valley.
• Participants were randomized to eGPC (including social support services) or eIPC (individualized psychosocial assessments).
• Depressive symptoms were measured using the Patient Health Questionnaire-9 (PHQ-9) from baseline to 3 months postpartum.

Main Results:

• Both eGPC and eIPC groups showed statistically significant reductions in depressive symptom severity from baseline to 3 months postpartum.
• No significant difference in the reduction of depressive symptoms was observed between the eGPC and eIPC groups (Cohen d = 0.1; P = .45).
• Participants in both care models experienced moderate improvements in maternal mental health.

Conclusions:

• Enhanced group prenatal care and enhanced individual prenatal care are both effective in improving depressive symptoms during the perinatal period.
• The study found no evidence that one enhanced prenatal care model was more effective than the other for reducing perinatal depression.
• Findings underscore the importance of comprehensive prenatal care addressing social determinants for maternal mental health.
