Population-level trends over a decade in geographical inequality for opportunity in access to maternal care services: a cross-sectional analysis from the National Family Health Surveys in India

Objectives The objective of this study is to examine the trends in geographical inequality of opportunity in maternal health services in India considering the Every Newborn Action Plan (ENAP) 2025 coverage targets.Setting India.Participants Women in the National Family Health Survey (NFHS)-NFHS-4 (2014-2015) and NFHS-5 (2019-2021).Primary and secondary measures District-level coverages of 4+antenatal care (ANC) visits, institutional delivery with skilled birth attendant, postnatal care (PNC) services within 48 hours of delivery, continuum of care (CoC) services for women with most recent live births were considered. Human Opportunity Index (HOI) documented the opportunities for equitable access to these services, ranging from 0 (high inequality) to 100 (universal access). HOI was compared between the survey rounds and wealth index (WI) quintiles that the women belonged to.Results Coverages of 4+ANC visits, institutional delivery, PNC and CoC in India increased by 22.8% (95% CI 22.1% to 23.5%), 12.6% (95% CI 12.2% to 12.9%), 28.5% (95% CI 28.0% to 29.0%) and 38.6% (95% CI 37.6% to 39.6%) between NFHS-4 and NFHS-5, respectively. The HOI for 4+ANC visits was 48.4 in NFHS-5, ranging from 11.3 to 92.4 in states and from 31.1 to 70.5 for WI I-V. The HOI for institutional delivery was 80.4 in NFHS-5, ranging from 37.4 to 99.7 in the states and from 21.0 to 100 for WI I-V. The HOI for PNC services was 73.5 in NFHS-5, ranging from 37.5 to 95.6 in the states and from 61.2 to 88.3 for WI I-V. The HOI for CoC was 37.1, ranging from 6.5 to 88.8 in the states and from 19.8 to 62.7 for WI I-V for CoC in NFHS-5.Conclusion Though significant improvements in the geographical inequity of maternal health services have been made in India, the geographical inequity for 4+ANC visits coverage lags significantly behind resulting in CoC coverage inequity to achieve the ENAP targets for these services.
