Black infants are more likely than white infants to be born prematurely, which has been associated with disparities in infant mortality and other chronic conditions.OBJECTIVE To evaluate whether Medicaid expansion was associated with changes in rates of low birth weight and preterm birth outcomes, both overall and by race/ethnicity.DESIGN, SETTING, AND PARTICIPANTS Using US population-based data from the National Center for Health Statistics Birth Data Files (2011-2016), difference-in-differences (DID) and difference-in-difference-in-differences (DDD) models were estimated using multivariable linear probability regressions to compare birth outcomes among infants in Medicaid expansion states relative to non-Medicaid expansion states and changes in relative disparities among racial/ethnic minorities for singleton live births to women aged 19 years and older.EXPOSURES State Medicaid expansion status and racial/ethnic category.MAIN OUTCOMES AND MEASURES Preterm birth (
