Objective：To analyze the correlation between elective cesarean delivery（ECD） and the risk of neonatal respiratory morbidity by Meta analysis． Methods：Twelve observational studies on relationship between ECD and neonatal respiratory morbidity were re－viewed and analyzed in this study. Random effect model and RevMan 5.0 software were adopted to analyze the data． Results：There were statistical differences in respiratory morbidity of full-term neonates between ECD and vaginal delivery（OR（95%CI）=3.43（2.18，5.14），P＝0.000）. There was no significant correlation in risk for neonatal respiratory disease between ECD and emergency cesarean section（OR（95%CI）=1.97（0.98，3.92），P=0.06）. Respiratory morbidity was significantly increased in neonates born after the 39th gestational week than in neonates born before the 39th gestational week（P＝0.000，OR（95%CI）=2.29（1.66，3.16））. Conclusions：ECD may associate with the risk of neonatal respiratory morbidity.Respiratory morbidity is higher in neonates born after the 39th gestational week than in neonates born before the 39th gestational week.
