摘　　要：目的:探讨我国北方地区足月妊娠妇女孕期体重增长的适宜范围。方法:收集我国北方地区5 072例单胎足月初产妇孕前、孕期及产后42天资料,按照中国成人体重指数(BM I)分类要求将5 072例孕妇分组,了解各组的孕期体重增长情况,分析各组不同孕期体重增长对母儿不良妊娠结局发生率的影响,从而为各组推荐孕期体重增长的适宜范围。结果:5 072例孕妇中,孕前BM I<18.5 kg/m2,18.5～23.9 kg/m2及≥24 kg/m2的孕妇分别占16.8%,66.8%及16.4%,不良妊娠结局发生率最低的孕期体重增长范围分别为12～18 kg,10.0～16.0 kg及8.0～14.0 kg,(P<0.05),推荐的孕期体重增长范围分别为12～18 kg,10.0～16.0 kg及8.0～14.0 kg。结论:我国北方地区孕前低、正常、超重及肥胖组孕妇的平均孕期体重增长均较高,建议其孕期体重增长范围分别控制在12～18 kg,10.0～16.0 kg及8.0～14.0 kg。Objective：To approach the optimal range of gestational weight gain for singloten term nulliparous pregnancies in north region of china.Methods：The information of 5 072 singleton nulliparous pregnancies delivered in Shenyang region were collected.The information contained pre-pregnancy,pregnancy and postpartum conditions of each woman.The 5 072 women were divided into three categories according to Chinese classification of body mass index（BMI）：pre-pregnancy underweight（18.5 kg/m2）,normal weight（18.5～24 kg/m2）,overweight and obesity（≥24 kg/m2）.The relationship between gestational weight gain and adverse pregnancy outcome and recommending optimal range for gestational weight gain were analyzed.Results：The rate of pre-pregnancy underweight,normal weight,overweight and obesity was 16.8 %,66.8% and 16.4%,respectively.The ranges of gestational weight gain which caused the lowest mobility of adverse pregnancy outcome were 12～18 kg,10.0～16.0 kg and 8.0～14.0 kg（P0.05）,respectively.The recommending optimal ranges of gestational weight gain were 12～18 kg,10.0～16.0 kg and 8.0～14.0 kg respectively.Conclusion：The average gestational weight gain is higher in north region of china.The recommending optimal ranges should be 12～18 kg,10.0～16.0 kg and 8.0～14.0 kg for the three categories respectively.
