For Health Care Providers: Information About the New Gestational Age Designations

Learn why the new term pregnancy definitions are important to ensuring the best outcomes for mom and baby.


A November 2013 American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal Fetal Medicine committee opinion replaced the use of “term” birth (gestation between 37 weeks and 42 weeks) with the following gestational age designations.

These new terms offer more specificity to accurately convey the distinction of health benefits and risks for each week of gestation from 37 weeks to 42 weeks. In the past, this entire period was considered “term,” implying that neonatal outcomes from deliveries at any point in this interval were uniform.


We now have strong evidence from research, conducted in part by the Eunice Kennedy ShriverNational Institute of Child Health and Human Development, that the risk for adverse outcomes is greater for neonates delivered in the newly created early-term period compared with those delivered after 39 weeks.


The terminology change communicates the results of this research to both health care providers and patients.
