Long-Term Outcomes of Moderately Preterm, Late Preterm, and Early Term Infants

摘要

At present, moderate preterm (MPT) infants born at 32 to 33weeks' gestation and late preterm (LPT) infants born at 34 to 36weeks' gestation make up the largest subgroup of preterm infants and contribute to more than 80% of premature births in the United States. There is increasing evidence that both MPT and LPT infants are at increased risk of neurologic impairments, developmental disabilities, school failure, and behavior and psychiatric problems. Population studies suggest that for each 1week decrease in gestational age below 39weeks, there are stepwise increases in adverse outcomes after adjusting for confounders.
