Until recently, infants born at moderate preterm (32-33 weeks) and late preterm (34-36 weeks) gestations have gone largely unstudied. Since their outcomes were thought to be similar to those of infants born at 37 weeks and above, they have historically been managed in much the same way as infants born at term. However, accumulating data indicate that risks of morbidity and mortality are significantly greater in this group than previously believed. Since moderate and late preterm infants account for around 6% of all births, very large numbers of babies are potentially affected. Although their problems may be less obvious than those of extremely preterm infants, the population impact of long-term health and neurodevelopmental problems in this group will be substantial. This review summarises the current available literature, highlights gaps in knowledge and discusses the implications of late preterm birth for both clinical practice and research in the perinatal period and beyond.
直到最近，中等早产儿（32-33 周）和晚期早产儿（34-36 周）的婴儿在很大程度上仍未得到充分研究。由于人们认为他们的结局与 37 周及以上出生的婴儿相似，因此他们在历史上的管理方式与足月出生的婴儿非常相似。然而，越来越多的数据表明，这一群体的发病率和死亡率风险明显高于此前的预期。由于中等早产儿和晚期早产儿占所有出生婴儿的 6%左右，因此可能会有大量婴儿受到影响。尽管他们的问题可能不像极早产儿那样明显，但这一群体长期存在的健康和神经发育问题对人口的影响将是巨大的。这篇综述总结了目前已有的文献，强调了知识空白，并讨论了晚期早产儿出生对围产期及以后临床实践和研究的影响。
