• Description:
  Preterm birth (delivery prior to 37 completed weeks of gestation) is a leading cause of infant mortality in the United States and around the world and has also been associated with long-term adverse outcomes in children (1,2). In the United States, the preterm birth rate rose 7% from 2014 to 2019, and then declined 1% from 2019 to 2020 (3). Changes in multiple births can impact overall preterm birth rates because of the greater likelihood of preterm delivery among infants born in multiple gestation pregnancies (3,4). Accordingly, to better identify factors associated with the 2019-2020 decline in preterm births, this report is limited to singleton births and describes trends in preterm birth rates from 2014 to 2020 and changes in rates between 2019 and 2020 by maternal race and Hispanic origin, age, and state of residence.
