| 摘要: |
| 目的探讨我国单胎孕妇适宜的孕前BMI分类和孕期增重范围。方法以2018年1月—2019年12月在北京妇产医院产科住院的的16 977名单胎孕妇为研究对象，随机选择其中2/3的孕妇数据（11 323例）进行参考值范围的计算，另外1/3的孕妇（5 654例）用作参考值范围的评估。以具有良好妊娠结局孕妇的孕前BMI的第25和第75百分位数作为分类的临界点，将孕前BMI进行分类。对不同BMI分类的孕妇，使用百分位数法计算适宜的孕期增重范围，并比较增重与不良妊娠结局的发生风险。结果孕前BMI＜19.2 kg/m2为孕前低体重，19.2≤BMI≤22.9 kg/m2为孕前正常体重，BMI＞22.9 kg/m2为孕前超重或肥胖。孕前低体重、正常体重以及超重或肥胖的妇女孕期适宜增重为12.0～17.0、11.5～17.0和10.6～16.0 kg。结论本研究推荐孕前BMI为19.2～22.9 kg/m2作为正常体重，对应的孕期增重范围能在一定程度上降低不良妊娠结局发生风险，更适合我国孕产妇情况，可为临床医生对孕妇的体重管理提供参考。 |

| Abstract: |
| ObjectiveTo explore the optimal range of body mass index(BMI) before pregnancy and gestational weight gain(GWG) for singleton pregnant women. MethodsThe BMI data and pregnant outcomes of 16 977 singleton pregnant women who delivered baby between January 2018 and December 2019 in the Beijing Obstetrics and Gynecology Hospital were retrospectively analyzed. Two thirds of the pregnant women(11 323 cases) were randomly selected as the training set, and the rest one third(5 654 cases) was selected as the validation set. The 25th and 75th percentile of pre-pregnant BMI of pregnant women with good pregnancy outcomes were selected as the cut-off value for classification. The optimal GWG ranges were calculated using P25-P75 of GWG among mothers who had good pregnant outcomes with different pre-pregnancy BMI classifications. ResultsBMI<19.2 kg/m2，19.2≤BMI≤22.9 kg/m2 and BMI＞22.9 kg/m2 were considered as low weight, normal weight and overweight or obese before pregnancy. Based on these, the recommended optimal ranges of GWG were 12.0-17.0, 11.5-17.0 and 10.6-16.0 kg for underweight, normal weight and overweight/obese pregnant women, respectively. Inappropriate pregnancy weight and GWG were associated with several adverse pregnancy outcomes. ConclusionThe pre-pregnancy BMI classification and optimal GWG range proposed in this study can reduce the risk of adverse pregnancy outcomes to some extent, which would be used for weight management of pregnant women. |
