Late-preterm birth refers to babies born between 34 and 36 weeks of pregnancy. More than 70 percent of premature babies are born at this time. While these babies are usually healthier than babies born earlier, they are 3 times more likely to die in the first year of life than full-term infants. They also are at increased risk of newborn health problems, including breathing and feeding problems. Some late-preterm births result from early induction of labor or cesarean delivery due to pregnancy complications. However, in some cases, early delivery may occur without good medical justification. Unless there are medical problems, women should wait until at least 39 weeks to schedule an induced labor or c-section to prevent possible prematurity-related problems in their babies.
