Survival Analysis of Under-five Mortality in West Sulawesi Indonesia using Cox Regression

Reducing infant mortality is one of the targets of SDGs goal 3, promoting wellbeing for all at all ages and ensuring healthy lives. Although the under-five mortality in Indonesia has declined, some provinces show a high mortality rate such as West Sulawesi. Hence, efforts to decrease the rate is still needed by identifying the main determinant of under-five mortality. The main objective of this study is to determine the main factors that affect under-five mortality in West Sulawesi using Intercensal Population Survey 2015. In this study, the impact of mother’s education, age of first delivery, previous birth interval, birth type, the gender of the underfive child, and paramedics help during labor were investigated using the Cox Proportional Hazard Regression. All variables impacted mostly to the survival rate of under-five children. Female under-five children had a lower hazard (risk) of death compared to the males. Twin had a three times higher hazard of death as compared to single born children. In addition, higher mother’s education tends to have a lower hazard.
