中文摘要: 摘 要 目的 分析二孩政策后影响闵行区巨大儿发生的危险因素。方法 采用回顾性整群抽样的方法，收集2016-2019年闵行区产检并分娩的单胎足月新生儿27221例。分析产妇孕前体重指数(BMI)、孕期增重、产次、年龄、户籍、妊娠期糖尿病、新生儿性别等因素对巨大儿发生的影响。结果 孕前超重肥胖组巨大儿发生风险(13.9％)是孕前标准体重组(7.0％)的2.0倍(OR=2.0)；孕期增重过多组巨大儿发生风险(11.9％)是孕期增重适宜组(5.4％)的2.2倍(OR=2.2)。年龄与新生儿性别对巨大儿发生率的影响有统计学差异。结论 二孩政策后孕前超重肥胖和孕期体重增长过多是巨大儿发生的主要因素，高龄也是引起巨大儿的危险因素之一。

Abstract:Abstract OBJECTIVE To analyze the risk factors of macrosomia in Minhang District after the two-child policy. METHODS A retrospective cluster sampling method was used to collect 27221 full-term singleton newborns who underwent prenatal examination and delivered in Minhang District from 2016 to 2019. Analysis of maternal body mass index (BMI), weight gain during pregnancy, parity, age, household registration, gestational diabetes mellitus, newborn sex and other factors on macrosomia. RESULTS The risk of macrosomia in the overweight and obesity group before pregnancy (13.9%) was 2.0 times higher than that in the normal weight group before pregnancy (7.0%) (OR = 2.0). The risk of macrosomia in the group with excessive weight gain during pregnancy (11.9%) is 2.2 times higher than that in the group with appropriate weight gain during pregnancy (5.4%) (OR=2.2). There are statistical differences between age and sex of newborn on the incidence of macrosomia. CONCLUSION Overweight and obesity before pregnancy and excessive weight gain during pregnancy after the two-child policy are the main factors of macrosomia, and old age is also one of the risk factors of macrosomia.
