Unraveling the Interplay of Race and Geography on Maternal Mortality in the United States
摘要
Maternal mortality in the United States disproportionately affects racial minorities and rural populations, yet limited research examines how these factors intersect to compound risks.
MethodsWe conducted a systematic review of four databases (PubMed, CINAHL, Google Scholar, Scopus) from 2015 to 2023, identifying studies that analyzed maternal mortality disparities by both race and geography in the United States. Using predetermined inclusion criteria, we extracted data on study design, population characteristics, and outcomes. A descriptive synthesis was performed due to methodological heterogeneity across studies.
ResultsSeven studies met inclusion criteria, drawing from national surveillance systems, state health departments, and hospital databases across diverse geographic regions. All studies documented significantly higher maternal mortality among Black women compared to White women, with adjusted odds ratios ranging from 1.65 to 1.81. Rural areas showed pregnancy-related mortality ratios up to 60% higher than large metropolitan areas. Intersectional analyses revealed a “double disparity” pattern where racial minorities in rural or socioeconomically disadvantaged areas faced compounded risks. Black women experienced 3.4 times higher pregnancy-related mortality across all geographic settings, while the most deprived neighborhoods showed 78% higher odds of severe maternal outcomes. Insurance gaps, particularly postpartum Medicaid coverage loss, emerged as a critical contributing factor.
ConclusionsThe intersection of racial minority status and rural residence creates compounded maternal mortality risks. Interventions must simultaneously address systemic racism in healthcare and expand rural obstetric services while ensuring continuous postpartum insurance coverage.
