Explaining socioeconomic disparities and gaps in the use of antenatal care services in 36 countries in sub-Saharan Africa

Abstract

Abstract Significant maternal and child deaths occur in sub-Saharan Africa (SSA) even with existing effective interventions. Antenatal care (ANC), for example, is an intervention that improves the health of pregnant women and their babies, but only 52% of pregnant women in SSA had the recommended minimum of four ANC visits between 2011 and 2016. While significant socioeconomic inequalities in ANC visits have been reported to the disadvantage of the poor, little is known about the depth of ANC coverage and associated inequalities. This paper introduces ‘deficits’ (i.e. the number of ANC visits that are needed to reach the recommended minimum of four ANC visits) and ‘surpluses’ (i.e. the number of ANC visits over and above the recommended minimum of four ANC visits) to assess socioeconomic inequalities in the indicator and depth of the ‘deficits’ and ‘surpluses’ in ANC visits. Using the latest available Demographic and Health Survey data for 36 SSA countries and concentration indices, the paper found that ‘deficits’ in ANC visits are more prevalent among poorer women compared to ‘surpluses’ that are concentrated among the rich. On average, women with ‘deficits’ in ANC visits require about two more ANC visits to reach the recommended four ANC visits, and women with ‘surpluses’ exceeded the recommended minimum by about two ANC visits. The factors that explain a substantial share of the socioeconomic inequalities in ANC ‘deficits’ and ‘surpluses’ in SSA include wealth, education and area of residency, which are essentially the social determinants of health inequalities. For policy response, it is suggested that education is a significant channel to affect the other social determinants of inequalities in ANC coverage reported in the paper. Thus, countries must prioritize quality education as addressing education, especially among women in SSA, will significantly reduce disparities in ANC service utilization and accelerate progress towards universal health coverage.
