The rate of premature birth in the United States is climbing, according to the infant and maternal health nonprofit March of Dimes. On Tuesday, the organization released its annual “report card” on maternal and infant health, which involves a newly updated calculation system. Taking an in-depth look at premature births, the new report found that the US preterm birth rate rose to 10.5% last year, representing an increase of 4% since 2020 and the worst national rate since March of Dimes started tracking this data in 2007, based on its new calculation system.
