Background
Inequality in maternal healthcare use is a major concern for low-and middle-income countries (LMICs). Maternal health indicators at the national level have markedly improved in the last couple of decades in Nepal. However, the progress is not uniform across different population sub-groups. This study aims to identify the determinants of institutional delivery, measure the wealth-related inequality, and examine the key components that explain the inequality.
Methods
Most recent nationally representative Multiple Indicator Cluster Survey (MICS) 2019 was used to extract data about married women (15–49 years) with a live birth within two years preceding the survey. Logistic regression models were employed to assess the association of independent variables with the institutional delivery. The concentration curves (CC) and concentration indexe (CIX) were used to analyze the inequality in institutional delivery. Wealth index scores were used as a socio-economic variable to rank households. Decomposition was performed to identify the determinants that explain socio-economic inequality.
Results
The socio-economic status of households to which women belong was a significant predictor of institutional delivery, along with age, parity, four or more ANC visits, education status of women, area of residence, sex of household head, religious belief, and province. The concentration curve was below the line of equality and the relative concentration index (CIX) was 0.097 (p < 0.001), meaning the institutional delivery was disproportionately higher among women from wealthy groups. The decomposition analysis showed the following variables as the most significant contributor to the inequality: wealth status of women (53.2%), education of women (17 %), residence (8.64 %) and ANC visit (6.84 %).
Conclusions
The pro-poor strategies are urgent to reduce the existing inequality between wealthy and poorer women. The strategies should focus on raising the education level of women especially from the rural and relatively backward province (Province 2). Increasing antenatal care (ANC) coverage through out-reach campaigns is likely to increase facility-based delivery and decrease inequality. Monitoring of healthcare indicators at different sub-population level (for example wealth, residence, province) is key to ensure equitable improvement in health status and achieve universal health coverage (UHC).
