Trends and Disparities in Infant and Child Mortality in Nigeria Using Pooled 2003 and 2008 Demographic and Health Survey Data

Abstract

We analyze infant and under-5 mortality trends in Nigeria using data from the demographic and health surveys (DHS) of 2003 and 2008. We use pooled data to enable us carry out logistic regression analysis at the state level and allow for robustness of our results. Our analysis shows wide disparities in both infant and under-5 mortality rates in the six geopolitical zones of Nigeria and the 36 states and the Federal Capital Territory Abuja. Furthermore, the results show highly significant differences in infant and under-5 mortality rates among the six geopolitical zones and among the 36 states of Nigeria. Our result shows that urban advantage over rural areas in under-5 mortality rate only exist among the richest quintiles in Nigeria. We find no evidence of statistically significant difference between the urban poorest and poorer quintiles and the rural poorest and poorer quintiles in both infant and under-5 mortality in Nigeria. We find wealth, educational attainment of the mother, the use of health facility, religion, gender of a child, and number of births in the last 3 years to be highly correlated with infant and under-5 mortality in Nigeria. Both infant and under-5 mortality rates declined between 2003 and 2008 in Nigeria.
