Pregnant women facing interpersonal racial discrimination are nearly 40% more likely to experience postpartum depression and have a more than 170% increased risk of delivering a baby with a very low birth weight, according to a systematic review published in 2026.
The analysis, encompassing three decades of research and over 1.5 million participants, identified racial discrimination as a potentially modifiable determinant of both maternal and neonatal health. Researchers argue that integrating assessments of racial discrimination into perinatal care and research is crucial to address health inequalities.
The review examined a range of adverse outcomes, including hypertensive disorders of pregnancy, gestational diabetes, mode of delivery, fetal growth, infant mortality, and neonatal intensive care unit admissions. While the strongest evidence supported a link between racial discrimination and postpartum depression – a 37% higher risk – a significant association was also found with low birth weight babies, with a 121% increased risk of delivering a baby with LBW and a 170% increased risk of delivering a baby with a very LBW. No statistically significant associations were found between racial discrimination and hypertensive disorders of pregnancy or gestational diabetes.
Researchers noted inconsistencies in findings related to preterm birth, with cohort studies showing no association while cross-sectional studies indicated a 19% increased risk. Evidence for other outcomes remained inconclusive.
The study points to psychosocial stressors stemming from racism as a key pathway contributing to these disparities. Experiences of interpersonal racial discrimination may contribute to postpartum depression through prolonged stress, social isolation, and strained relationships during and after pregnancy. The link between racial discrimination and low birth weight could be influenced by maternal stress, placental dysfunction, metabolic dysregulation, and inflammatory processes, the researchers suggest.
Experts are increasingly framing discrimination as a public health issue, advocating for routine assessment of social stressors alongside standard mental health screenings during and after pregnancy. Current clinical guidelines largely fail to explicitly recognize racial discrimination as a risk factor for maternal and neonatal health, a gap the researchers argue needs to be addressed.
The magnitude and consistency of the observed associations, researchers state, necessitate systematic attention and call for structural interventions at the policy level to address discrimination as a public health concern, rather than solely an individual experience.
The systematic review and meta-analysis was published in Frontiers in Reproductive Health in 2026 (Adesunkanmi M et al. Self-reported experiences of interpersonal racial discrimination and maternal and neonatal health: a systematic review and meta-analysis. 2026. 8:DOI:10.3389/frph.2026.1783126).
Recent reports from KFF highlight existing racial disparities in maternal and infant health, while research from Boston Medical Center and Johns Hopkins Bloomberg School of Public Health have also focused on the impact of systemic racism and the Black maternal health crisis.
