Determinants of Under-Five Child Mortality in Bangladesh: Findings from Bangladesh Demographic Health Survey 2017-18

Abstract: Under-five mortality has remained a significant public health concern in Bangladesh despite a consistent decline over the previous few years. The purpose of this study was to identify the socioeconomic and demographic risk factors for under-five mortality in Bangladesh. Data from the 2017–18 Bangladesh Demographic and Health Survey are used in the study. The study outcome variable was survival time, which was obtained from the variable age at death for the event and the current age of the child for the censored observation. Based on literature assessment, nine covariates were chosen for this study. Product-Limit (P-L) estimator and Log-Rank tests were performed to assess the association between the outcome variables and the selected covariates. The Cox proportional hazard model was also employed in this study to identify potential risk factors for under-five mortality. After fitting the Cox PH model, the factors that significantly affect under-5 mortality include mother's age at birth ( 30), and Sylhet division. Children whose mothers were under 20 and over 30 years old have mortality rates that are 47.5% and 68.7% higher, respectively, than children whose mothers were between the ages of 20 and 30. Regional differences had an impact on child mortality as well. Children in the divisions of Barisal, Rangpur, Khulna, Mymensingh, and Sylhet had death rates that were, in comparison to children in the division of Dhaka, 5.5%, 7.8%, 9.6%, 11.2%, and 55.3% higher.
