摘　　要：目的比较孕前不同体重指数(BMI)产妇的孕期体重增加和新生儿体格发育情况。方法消除身高对体重增加的影响,999名单胎初产妇按孕前BMI分为低体重组(LG,n=168)、正常体重组(NG,n=600)和肥胖组(FG,n=231)。结果 FG组孕期体重增加和△BMI均较NG组少(P<0.01)。三组普遍存在孕期增重超标的现象。NG组新生儿身长、体重较其他两组结果高(P<0.01);NG组的胎儿生长指数高于LG组(P<0.01)。结论妇女孕期增重超标现象普遍。孕前BMI处于正常范围产妇分娩的新生儿在宫内生长和最终体格发育结果最好。Objective To compare the gestational weight gain and neonatal physical development in different BMI woman before pregnancy.Methods For eliminating the effect of height on weight gain,999 primiparas with single birth were selected and divided into three groups according to pre-pregnancy BMI,including lean group（LG,n=168）,normal group（NG,n=600） and fat group（FG,n=231）.Results The gestational weight gain and the increasing rage of BMI of FG were significantly fewer than those of NG（P0.01）.Excessive weight gain during pregnancy was widespread.The neonatal length and weight of NG were significantly higher than other groups（P0.01）;Fetal growth ratio of NG was significantly higher than LG（P0.01）.Conclusions Excessive weight gain during pregnancy is widespread.Intrauterine growth and neonatal physical development are better,which delivered by maternity in the normal range of pre-pregnancy BMI.
