Protective role of health insurance coverage in reducing under-five mortality in Ethiopia: Gompertz inverse-Gaussian shared frailty modelling.

objectiveTo determine the association between health insurance coverage and under-five mortality in Ethiopia using data from the 2016 Ethiopia Demographic and Health Survey (EDHS).

methodsThe current study used a total of 10 641 under-five children from the 2016 EDHS. To identify the predictors, the Gompertz inverse-Gaussian shared frailty model was fitted. The theta value, Akaike Information Criteria and Bayesian Information Criteria were applied for model evaluation, and variables with p values less than 0.2 were included in the multivariable analysis. The strength and statistical significance of the associations were demonstrated by reporting the adjusted HR (AHR) with a 95% CI in the multivariable Gompertz inverse-Gaussian shared frailty model.

resultsAccording to the study's findings, 96.46% of the children were born to mothers not covered by health insurance. The study found that health insurance coverage was significantly associated with a lower risk of under-five mortality (not covered: AHR=0.13; 95% CI 0.02, 0.95). Other factors that showed significant associations with under-five mortality include place of residency, family size, twin status, place of delivery and preceding birth interval.

conclusionThe findings indicate that health insurance coverage in Ethiopia is significantly associated with a lower risk of mortality among children under five. However, coverage remains low among mothers of these children, highlighting an urgent need for policies and interventions aimed at expanding health insurance coverage and addressing key determinants of child health to reduce under-five mortality and improve child survival outcomes. Addressing gaps in health insurance and other contributing factors is vital for creating effective strategies to lower under-five mortality rates.
