Wealth Status, Health Insurance, and Maternal Health Care Utilization in Africa: Evidence from Gabon

BACKGROUND: To achieve the universal health coverage among other Sustainable Development Goals, African countries have shown the commitment by implementing strategies to improve access and coverage of health care services whose access is still very low. The achievement of universal health care requires the provision and availability of an adequate financing system. This study explored the wealth-related association of compulsory health insurance on maternal health care utilization in Gabon. METHODS: The study used the 6(th) round of Gabon Demographic and Health Surveys (GDHSs)—2012 data to explore three outcome measures of maternal health care utilization extracted on number of antenatal care (ANC) visits during pregnancy, place of birth delivery, and postnatal health care. The dependent variable was women with health insurance coverage against those without. Logistic regression and propensity scoring matching analysed associations of health insurance coverage on women's utilization of health care. RESULTS: Mean (+/− SD) age of women respondents of reproductive age was 29 years (9.9). The proportion of at least 4 antenatal care visits was 69.2%, facility-based delivery was 84.7%, and postnatal care utilization was 67.9%. The analysis of data showed disparities in maternal health care services utilization. The GDHS showed maternal age, and geographical region was significantly associated with maternal health care service utilization. A high proportion of urban dwellers and Christian women used maternal health care services. According to the wealth index, maternal health services utilization was higher in women from wealthy households compared to lower households wealth index (ANC (Conc. Index = 0.117; p ≤ 0.001), facility-based delivery (Conc. Index = 0.069; p ≤ 0.001), and postnatal care (Conc. Index = 0.075; p ≤ 0.001), respectively). With regard to health care insurance coverage, women with health insurance were more likely to use ANC and facility-based delivery services than those without (concentration indices for ANC and facility-based delivery were statistically significant; ANC: z-stat = 2.69; p=0.007; Conc. Index: 0.125 vs. 0.096 and facility-based delivery: z-stat = 3.38; p=0.001; Conc. Index: 0.076 vs. 0.053, respectively). CONCLUSION: Women enrollment in health insurance and improved household's financial status can improve key maternal health services utilization.
