孕前体重指数及孕期增重对围生结局影响 　　[摘要]目的 探?孕前体重指数及孕期增重对围生结局的影响。方法 选取2015年1月～2017年7月在我院产科门站建档和住院分娩的476例孕妇作为研究对象，计算孕前BMI、追踪孕期增重、临分娩前体重、新生儿出生体重及分娩结局。根据我国BMI的分类标准分组，分为低体重组56例，正常体重组253例，超重组126例，肥胖组41例；根据孕期增重分为孕期增重不足组60例，孕期增重适宜组300例，孕期增重过多组116例。结果 按BMI分组，四组孕妇GDM、巨大儿的发病率及剖宫产率差异有统计学意义（P0.05）。低体重组巨大儿的发病率及GDM的发病率均为0，剖宫产率为26.78%，正常体重组的GDM发病率为7.11%，巨大儿发病率为4.74%，剖宫产率为37.54%，超重组的GDM发病率为14.28%，巨大儿发病率为7.94%，剖宫产率为54.76%，肥胖组的GDM发病率为24.39%，巨大儿的发病率为24.39%，剖宫产率为60.97%；根据孕期增重分组，孕期增重过多的孕妇GDM、巨大儿、剖宫产率高于增重不足及正常增重的孕妇（P0.05），孕期增重不足组的GDM发生率为3.33%，巨大儿发病率为1.67%，剖宫产发病率为30.00%，孕期增重适宜组，GDM发生率为6.33%，巨大儿发病率为6.00%，剖宫产率为40.33%，孕期增重过多组，GDM的发生率为21.55%，巨大儿发生率为11.21%，剖宫产率为56.03%。结论 孕前体重指数及孕期增重过多GDM、巨大儿发生率及剖宫产率均增高。 　　[关键词]孕前体重指数；孕期增重；GDM；巨大儿；剖宫产率 　　[中图分类号] R714 [文献标识码] A [文章编号] 1674-4721（2017）12（b）-0062-03 　　[Abstract]Objective To explore the influence of pre-pregnancy body mass index （BMI） and weight gain during pregnancy on the outcome of cesarean section.Methods 476 cases of pregnant women，who were checked and had hospital delivery in our hospital from January 2015 to July 2017，were selected as the research objects；the BMI before pregnancy was calculated；weight gain during pregnancy，body weight before delivery，neonatal birth weight and birth outcomes were also traced.The subjects were classified in accord with the China BMI classification standard，including underweight group with 56 cases，normal weight group with 253 cases， overweight group with 126 cases and obese group with 41 cases；according to the weight gain during pregnancy，they were classified into deficient-gain group with 60 cases，normal-gain group with 300 cases，excessive-gain group with 116 cases.Results Based on BMI classification，the pregnant women′s GDM rate，macrosomia rate and cesarean section rate of the four groups were significantly different，which were statistically significant （P 　　[Key words]Pregnancy BMI；Weight gain during pregnancy；Gestational diabetes mellitus；Macrosomia；Cesarean section rate 　　随着经济的发展，生活方式的改变，劳动强度的下降，使超重和肥胖的发生率逐年上升[1]，
