In England and Wales, 19% of live births in 2012 were at 37-38 weeks' gestation, equating to nearly 140 000 early-term births each year. Since caesarean sections (CS) are often performed at early-term gestations, this accounts for some of the increased proportion of the early-term births. Infants born early-term are at an increased risk of neonatal respiratory morbidity particularly if they are delivered by caesarean section. The long term lung function data are limited but available data suggest that early-term delivery is associated with respiratory morbidity in childhood. CS also appears to be associated with increased neonatal morbidity and future development of respiratory symptoms. However, future studies need to confirm the independent effects of caesarean sections and early-term deliveries particularly for long term outcomes as both are likely to affect the respiratory system differently.
在英格兰和威尔士，2012年19%的活产婴儿为妊娠37至38周出生，相当于每年有近14万例早产。由于剖宫产（CS）常在早产时进行，这是早产比例增加的部分原因。早产婴儿患新生儿呼吸系统疾病的风险增加，尤其是通过剖宫产分娩的婴儿。长期肺功能数据有限，但现有数据表明早产与儿童期呼吸系统疾病有关。剖宫产似乎也与新生儿发病率增加和未来出现呼吸道症状有关。然而，未来的研究需要证实剖宫产和早产的独立影响，特别是对于长期结果，因为两者可能对呼吸系统有不同影响。
