摘　　要：目的:探讨社会因素剖宫产对儿童体格与智力发育的影响。方法:采用前瞻性队列研究,确定社会因素剖宫产和顺产产妇队列(社会因素剖宫产组68例、顺产组65例),分别于出生时、18月龄、24月龄、30月龄、36月龄、42月龄时体格检查,24月龄时智力测验(采用Gesell评分)。结果:两队列均衡性较好(P>0.05),两组儿童在身高、体重、头围以及智力发育方面差异均无统计学意义。结论:社会因素剖宫产对42月龄以下的儿童体格发育未见显著性影响,社会因素剖宫产智力发育并不优于顺产,远期影响仍需扩大样本量以及继续随访研究。Objective： To explore the effect of elective cesarean section on physical and intellectual development in children. Methods： Using the prospective cohort study, a 133 newborn sample composed by 68 newborns delivered by cesarean section and 65 newborns by spontaneous delivery in a county of Chongqing was established from March to May, 2002.

Intellectual development was tested by Gesell mark at 2 years old. Results ： The factors had equilibrium in two cohorts （ P 〉 0. 05 ） . There had no significant difference of weight, height or length, head circumference and Intellectual development between the two groups. Conclusion ： There＇s no significant effect of cesarean section on physical growth of children below 4 years old. Intellectual development of the children delivered by cesarean section is no better than that of spontaneous delivery. Forward affect needs more samples and continual follow - up.
