During pregnancy, women of color (WOC) are at a disproportionate risk of adverse health outcomes that ultimately affect themselves and their newborns. There are extensive reasons for these racial health disparities, and current literature suggests that racial microaggressions may play an influential role. We examined racial microaggressions and birth outcomes in 2400 white and WOC mothers using an online survey. Microaggressions within the healthcare system were predictive of poor neonatal outcomes and maternal morbidity.
