Originally published in 2014, this report offers a comprehensive picture of infant mortality in Tennessee during the years 2003-2012. It examines state trends in infant mortality rates and differences across regions and counties, by age at death and among racial/ethnic groups. Leading causes of infant deaths are also examined, both statewide and again by region, age at death and race/ethnicity. Important infant mortality risk factors are explored, including low birthweight, preterm birth, maternal smoking and others. Also included are focused discussions of sudden unexplained infant deaths, perinatal regionalization and its role in the delivery and care of very low birthweight infants, and early term deliveries.
