Analysis of 21,465 Nigerian women revealed that higher education increased adequate prenatal care attendance by 5.6-fold, while the wealthiest quintile showed 3.9 times higher attendance compared to the poorest. Women with education also initiated care 35% faster than uneducated counterparts, starting at 5 months gestation rather than WHO's recommended 3 months. This finding illuminates a critical pathway for reducing maternal mortality in sub-Saharan Africa, where Nigeria accounts for nearly one-fifth of global maternal deaths. Education appears to overcome geographic barriers entirely—urban residence lost all statistical significance once education and wealth were accounted for, suggesting that apparent urban advantages stem purely from concentrated educational resources. The massive effect sizes underscore how profoundly educational access shapes reproductive health outcomes. However, this preprint analysis of cross-sectional survey data awaits peer review, and observational findings cannot establish causation. The research represents confirmatory evidence for education-focused interventions but highlights an urgent need for targeted girls' education programs and wealth-sensitive healthcare financing, particularly in Nigeria's underserved northern regions where maternal mortality remains devastatingly high.
