Preterm and early-term birth rates increased significantly from 2014 to 2022, with a 42% increase in births at 37 weeks’ gestation, according to CDC researchers. Rates of late-term and post-term births fell during the same period.
“The rate of preterm birth in the United States rose by more than one-third from 1981 to 2006. This rise prompted concern and a heightened awareness of the morbidities associated with births delivered at 34 to 36 weeks of gestation, or late preterm. … Late preterm and early-term births declined for several years, from 2007 to 2014, but have been on the rise in recent years,” wrote Joyce A. Martin, MPH, and Michelle J.K. Osterman, MHS, both epidemiologists at the CDC.
