Understanding Infant Mortality: Key Causes and Statistics by Gestational Age and Geography

This comprehensive analysis explores the critical factors influencing infant mortality, with a focus on data from the University of Alabama at Birmingham's Division of Neonatology. We examine mortality rates by country, state, and gestational age, along with causes of death in liveborns such as extreme prematurity, congenital heart defects, and infections. Additionally, the impact of maternal health, including steroid usage, and survival rates for infants born at varying gestational ages are highlighted. This research aims to inform preventative measures and improve neonatal care outcomes.
