Expanding the Evidence on Late Preterm Steroids to Twin Pregnancies

Nearly 60% of all preterm births in the United States occur in the late preterm period, defined as a birth after 34 weeks but before 37 weeks of gestation. In 2022, nearly 280 000 pregnant individuals and their neonates experienced a late preterm birth. While neonates born in this period generally have fewer complications of prematurity than those born before 34 weeks, many will require admission to an intensive or intermediate care unit before they are ready for discharge, and respiratory complications, including respiratory distress syndrome, remain a significant source of neonatal morbidity.
