Determinants of under-5 mortality in Burkina Faso

Abstract

Abstract Background The aim of this article is to determine the factors associated with under-5 mortality and their evolution from 1993 to 2010 and to analyse the contributors of socioeconomic inequalities in mortality of children under-5 years during the same period. Data and methods The data used in this study were derived from the four rounds of Demographic and Health Survey (DHS) conducted in Burkina Faso in 1993, 1998 and 2010. Concentration measurement, logistics regression and Oaxaca–Blinder decomposition method were used to analyse data. Results Multivariate analysis revealed that being the first child (odds ratio = 1.8 for 1993, 1.7 for 1998, 1.2 for 2003 and 1.3 for 2010) or a twin (odds ratio = 4.5 for 1993, 2.8 for 1998, 2.7 for 2003 and 4.8 for 2010) were also significantly associated with the probability of dying. The variable (parity) was the main contributor to the part of the inequality due to differences in group characteristics and that would be due to the fact that women from poor households have greater parity compared to those from rich households. Conclusion For a reduction in mortality and inequalities related to mortality, the implementation of actions in favour of poor households and promotion of family planning programmes for birth spacing will be required.
