Abstract: Objective To analyse the influence of different delivery status on school-age children's learning ability. Methods A total of 4 983 children during 6~12 years old in Kunshan city were selected through cluster sampling Method.They and their teachers or parents were surveyed about learning ability and their delivery status.Multiple linear regression was used to analyze the influence of different delivery status on school-age children's learning ability. Results The average score of 4 983 children's learning ability was (4.26±50.52).The average score of the girls' learning ability (4.35±0.48) was higher than that of the boys' (4.18±0.53)(P<0.05).The average learning ability score of children in high grade (4.36±0.52) was higher than that of the children in middle (4.23±0.52) or low grade (4.18±0.49)(P<0.05).Multiple linear regressions found there was no statistical significance of the influence of cesarean and dystocia on the school-age children's learning ability after adjustment for gender and grade level.However,prematurity and postterm pregnancy could reduce the average score of children's learning ability after adjustment for gender and grade level,and the reduced score were 0.07 and 0.08,respectively. Conclusion Prematurity and postterm pregnancy could influence the school-age children's learning ability.

摘要： 目的 分析不同分娩方式和分娩孕周对学龄期儿童学习能力的影响。方法 采用整群随机抽样的方法,在昆山市抽取的4 983名6~12岁儿童(其父母、老师等)进行不同分娩状态及学龄期学习能力等相关因素的问卷调查。采用多重线性回归来分析不同分娩方式和分娩孕周对学龄期儿童学习能力的影响。结果 本次研究共纳入研究对象4 983例,其学习能力平均分为(4.26±0.52)分,其中女生的学习能力平均分[(4.35±0.48)分]显著高于男生[(4.18±0.53)分](P<0.05),高年级的学习能力平均分[(4.36±0.52)分]高于中年级[(4.23±0.52)分]和低年级[(4.18±0.49)分](P<0.05)。多重线性回归分析发现,调整了性别、年级的影响后,以顺产作为参比组,剖宫产和难产对学龄期儿童学习能力的影响尚无统计学意义;以足月产儿童为参比,早产的学龄期儿童其学习能力平均分会降低0.07分,过期产的儿童其学习能力平均分会降低0.08分。结论 早产和过期产对学龄期儿童的学习能力存在一定影响。
