Under-5 Child Mortality Determinants in Rural-Urban Areas of Bangladesh: Proportional Hazard Models

Abstract

The People’s Republic of Bangladesh is a South Asian country with a vast population. The early childhood mortality is a noticeable public health problem. The study work aims to determine the factors related to under-5 aged child mortality in both rural and urban areas of Bangladesh; data pulled out from BDHS (Bangladesh Demographic and Health Survey)-2014. In rural and urban areas, 5306 and 2454 less than five years aged children born before in 5 years preceding the survey respectively. The Kaplan-Meier log-rank test is applied to determine the risk factors in bivariate analysis to multivariate survival models. In multivariate analysis to find out the risk factors of under-five aged child mortality, the Cox proportional hazard model and the Cox frailty model were employed. Religion, father’s educational level, number of antenatal care visits, multiplicity of birth, child size at birth, place of delivery, total children ever born, number of living children are the significant factors of child mortality in rural, urban areas. The variability among children for mortality is 0.000529 and 0.001225 in rural and urban areas individually. Proper notable attention needed for significant determinants, which may increase child survival.
