A Call to Action: Addressing the Public Health Crisis of Racial Inequities in Maternal Mortality and Pregnancy-Associated Breast Cancer

The United States faces a worsening maternal mortality crisis that starkly contrasts with trends in other high-income nations. Maternal mortality rates (MMRs) have more than doubled over the past two decades, rising from 9.65 deaths per 100,000 live births in 1999–2002 to 23.6 in 2018–2021, with approximately 700 deaths annually. Black and American Indian/Alaska Native women experience maternal mortality rates two to three times higher than their White counterparts, reflecting persistent structural inequities rather than biological differences. This narrative review synthesizes current evidence on the underlying drivers of racial inequities in maternal mortality and evaluates evidence-based interventions and policy strategies to address these disparities. A comprehensive literature review between 2000 and 2025 was conducted using databases including PubMed, Scopus, Web of Science, and Google Scholar, focusing on studies examining clinical, social, and structural determinants of maternal health outcomes, as well as evidence-based interventions and maternal health policy. Targeted searches of policy reports and grey literature were also performed to identify relevant policy initiatives and system-level interventions. Key contributors to disparities include underlying health conditions, postpartum mental health inequities, provider shortages, and limited access to postpartum care, with pregnancy-associated breast cancer (PABC) representing a less common but clinically significant risk factor that warrants further investigation in the context of racial inequities. Structural racism and socioeconomic disparities further exacerbate inequities through differential access to care, treatment bias, and barriers to healthcare utilization. System-level challenges, including workforce shortages, maternity care deserts, and the absence of federally mandated paid maternity leave, disproportionately impact marginalized populations. Although policy initiatives such as Medicaid postpartum coverage extensions, the Maternal Health Momnibus Act, and Maternal Mortality Review Committees represent important progress, they remain insufficient without broader structural reform. Evidence-based interventions, including midwife- and doula-led care, community-based peer support, and culturally tailored mental health programs, demonstrate measurable improvements in maternal outcomes. Outcomes of this review highlight the need for a comprehensive, equity-centered approach to reducing maternal mortality disparities, emphasizing structural reform, expanded access to care, strengthened data systems, and community-driven solutions.
