Background: There is a growing body of evidence on the inequality in the use of maternal health carernservices. However, there is little evidence in the literature describing the status of inequality in use ofrnquality of healthcare service. Particularly, there is a paucity of high-quality evidence on whether qualityrnantenatal care (ANC) is being fairly distributed across the various subgroups of population in Ethiopia.rnThis study aimed to examine the extent of inequalities in quality antenatal care and its drivers in Ethiopiarnusing data from the most recent standard Ethiopia Demographic and Heath Survey. rnMethods: Cross sectional survey data from 2016 Ethiopia Demographic and Health Survey (EDHS) werernused. The EDHS samples were selected through a stratified, two stage clustered sampling technique. Tornexamine inequalities quality ANC was measured by using six WHO recommended ANC service elements.rnThe inequality was assessed with respect to the selected equity stratifiers namely, region, place ofrnresidence, wealth quintile, maternal age and maternal education. We employed both the simple (ratio andrndifference) and complex (concentration index) measures of inequality. Further, wealth based inequalityrnwas decomposed to understand drivers under pinning the observed inequality. rnResult: The simple summary measure of inequality for the region showed high disparity across regionrnwith highest ANC quality (Addis Ababa region) and lowest (Afar region), difference (D)= 0.0690, 95%rnCI (0.0086, 0.1294) and the ratio Â®=1.3844 with 95% CI (1.0227, 1.8946). Also showed maternal agernbased inequality with D=0.0864, 95% CI (0.0077, 0.1652) and R=1.4728, 95% CI (1.0328, 2.1004) valuernindicated that women aged above 20 while giving birth were more likely to have quality of ANC service.rnHowever, insignificant disparity was observed for place of residence difference (D) = 0.0298, 95% CI (0.0368,rnrn0.0964) and ratio (R)=1.1368, 95% CI (0.8589, 1.5046). Concentration index for wealth andrneducation based inequality was 0.15 and 0.21 respectively, indicating pro-rich and pro-educated scenariornof the use of quality ANC. The decomposition analysis indicated that the main contributors of the wealthrnbased inequality were region, wealth status, education, frequency of ANC visit, type of ANC facility andrnprovider. rnConclusion and recommendation: There were glaring inequalities in the receipt of quality ANC inrnEthiopia. It needs high impact target interventions focused on region, wealth and frequencies of ANCrnwere the main contributors together accounted for nearly three-fourth of the wealth driven inequality.
