Variation in Preterm Birth Rates Across County Level

JAMA Network

About The Study: In this analysis of U.S. county-level preterm and early preterm birth rates, substantial geographic disparities were observed, which were associated with place-based social disadvantage. Stability in aggregated rates of preterm birth at the national level masked increases in nearly 1 in 6 counties between 2007 and 2019.
