在过去，从预产期前3周到预产期后2周这段时间被认为是“足月”，人们期望在这段时间内分娩的新生儿结局是一致和良好的。然而，越来越多的研究表明，新生儿结局，特别是呼吸道疾病，取决于5周孕龄范围内的分娩时间。为了解决这种缺乏一致性的问题，2012年底召开了一个工作组，建议将“足月”标签替换为早期足月（37 0/7妊娠周至38 6/7妊娠周）、足月（39 0/7妊娠周至40 6/7妊娠周）、晚期足月（41 0/7妊娠周至41 6/7妊娠周）、和postterm（42 0/7周及以上）更准确地描述分娩发生在或超过37 0/7周妊娠。美国妇产科医师学会和母胎医学学会支持并鼓励所有临床医生、研究人员和公共卫生官员统一使用工作组推荐的新胎龄指定，以促进数据报告、提供高质量的卫生保健和临床研究。
In the past, the period from 3 weeks before until 2 weeks after the estimated date of delivery was considered "term," with the expectation that neonatal outcomes from deliveries in this interval were uniform and good. Increasingly, however, research has shown that neonatal outcomes, especially respiratory morbidity, vary depending on the timing of delivery within this 5-week gestational age range. To address this lack of uniformity, a work group was convened in late 2012, which recommended that the label "term" be replaced with the designations early term (37 0/7 weeks of gestation through 38 6/7 weeks of gestation), full term (39 0/7 weeks of gestation through 40 6/7 weeks of gestation), late term (41 0/7 weeks of gestation through 41 6/7 weeks of gestation), and postterm (42 0/7 weeks of gestation and beyond) to more accurately describe deliveries occurring at or beyond 37 0/7 weeks of gestation. The American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine endorse and encourage the uniform use of the work group's recommended new gestational age designations by all clinicians, researchers, and public health officials to facilitate data reporting, delivery of quality health care, and clinical research.
