Parametric modeling of under-5 children survival among 30 African countries: Lognormal accelerated failure time gamma shared frailty model.

ABSTRACT:

Background

Under-five mortality continues to be a serious public health concern in low-and middle-income countries, particularly in Africa. This study investigates the probability of under-five survival and its predictors of mortality in the African continent using a recent demographic health survey from 2014-2022.

Methods

This study utilized recent Demographic and Health Survey data from 30 African countries, encompassing 226,862 live births. This study employed a multivariable lognormal accelerated failure time gamma shared frailty parametric survival regression analysis to identify the predictors of time-to-death among under-five children in these African nations.

Result

The overall under-five child mortality rate in Africa was 37.55 per 1,000 live births (95% CI:
