**Background:**
Maternal health care service use in low- and middle-income countries is known to vary by socioeconomic factors, but disparities specifically linked to women's empowerment have been underexplored. This study aimed to quantify and decompose inequalities in the uptake of early ANC, four or more ANC visits, quality ANC, and PNC within 2 days of birth using women's empowerment as the equity stratifier in Ethiopia.
**Methods:**
Data were drawn from four rounds of the Ethiopia Demographic and Health Surveys (EDHS) conducted in 2000, 2005, 2011, and 2016. The pooled sample included 15,367, 14,070, 16,515, and 15,683 women aged 15–49 across the four surveys, with response rates of 97.8%, 95.6%, 95.0%, and 94.6%, respectively. Women's empowerment was measured using the SWPER Global index, which captures three domains: attitude towards violence, social independence, and decision-making. Each domain was categorized into low, medium, and high empowerment. Inequalities were assessed using the Erreygers normalized concentration index (ECI) and concentration curves. Decomposition analysis using generalized linear models with binomial family and logit link was performed to identify the percent contribution of explanatory variables (e.g., wealth, education, residence, region, media exposure, survey year, and the empowerment domains themselves) to the observed inequalities. All analyses accounted for the complex survey design using Stata v16.
**Key Results:**
All maternal health services were disproportionately concentrated among highly empowered women across all three empowerment domains. For the attitude towards violence domain, the ECIs were: quality ANC 0.240 (95% CI 0.207, 0.273); early ANC 0.083 (95% CI 0.071, 0.095); at least four ANC 0.122 (95% CI 0.106, 0.138); PNC within 2 days 0.067 (95% CI 0.053, 0.081). For the social independence domain, ECIs were: quality ANC 0.20 (95% CI 0.169, 0.231); early ANC 0.067 (95% CI 0.055, 0.079); at least four ANC 0.122 (95% CI 0.108, 0.136); PNC 0.071 (95% CI 0.057, 0.085). For the decision-making domain, ECIs were: quality ANC 0.122 (95% CI 0.087, 0.157); early ANC 0.065 (95% CI 0.053, 0.077); at least four ANC 0.092 (95% CI 0.074, 0.11); PNC 0.057 (95% CI 0.043, 0.071).
Decomposition analysis revealed that the largest contributors to these inequalities included wealth (e.g., richest wealth contributed 7.7%–24.3% depending on service and domain), maternal education (secondary education contributed 6.1%–15.7%), rural residence (6.9%–10.8%), survey year (especially 2016, contributing 12.4%–42.8%), and the women's empowerment domains themselves (e.g., high decision-making contributed 36.5%–37.7% for at least four ANC). Rural residence had negative elasticities and concentration indices but positive percentage contributions, indicating that poorly empowered women clustered in rural areas were disproportionately unable to access services, widening the gap.
**Clinical Implications:**
The study demonstrates that women's empowerment-based inequalities in maternal health care are substantial and are driven by unequal distribution of socioeconomic determinants such as wealth, education, and geographic location. Policymakers should adopt redistributive and pro-poor policies to equitably distribute these determinants between empowered and poorly empowered women. The findings also highlight the need to integrate intersectionality frameworks into national health strategies, such as Ethiopia's 10-Year Development Plan (2021–2030), to address the compounded disadvantages faced by women who are poor, uneducated, and live in rural areas. Achieving SDG targets 3.8 and 5.6 by 2030 will require explicit prioritization of gender equality and women's empowerment in health policy.
