A birth cohort study of 4912 Brazilian infants showed that the incidence and duration of breast feeding for children delivered vaginally and for those born by elective caesarean section were similar. Those delivered by emergency caesarean section, however, were not breast fed for as long. This difference persisted after adjustment for confounding variables.
一项针对4912名巴西婴儿的出生队列研究表明,经阴道分娩的儿童与择期剖宫产出生的儿童在母乳喂养的发生率和持续时间方面相似。然而,急诊剖宫产出生的儿童母乳喂养时间较短。在对混杂变量进行调整后,这种差异仍然存在。
