【摘要】：目的:评估中国健康孕妇人群中,母亲孕前体质量指数和孕期增重对新生儿出生体重的影响,以期能指导合理的孕期增重。创新点:选择的人群为健康妊娠的中国孕妇,研究结果可为这一数目庞大的特定人群的孕期甚至孕前体重控制提供一定的理论基础。首次发现了孕前体质量指数可影响孕期各阶段增重与新生儿出生体重之间的关系。方法:本文做了一个样本为3772例中国孕妇的回顾性研究。根据孕前体质量指数将人群分为四组,分别为低体重组(18.5 kg/m2)、正常体重组(18.5 23.9 kg/m2)、超重组(24.0 27.9 kg/m2)和肥胖组(≥28.0 kg/m2)。比较这四组间新生儿出生体重的差异,并用多元分析的方法探究孕前体质量指数、孕期增重和新生儿出生体重之间的关系。结论:孕妇孕前体质量指数和孕期增重均与新生儿出生体重呈正相关(表2),极端的孕前体质量指数和孕期增重均会增加异常新生儿出生体重的风险(表3);孕期各阶段增重对新生儿出生体重的影响程度可能还受到孕前体质量指数的影响(表2)。对中国妇女来说,已有的孕期增重指南似乎并不十分合适(图2),制定一个有效的指南刻不容缓。
[Abstract]:Objective: to evaluate the effect of maternal weight index (PMI) and weight gain during pregnancy on the birth weight of newborns in Chinese healthy pregnant women in order to guide the reasonable weight gain during pregnancy. The results provide a theoretical basis for weight control during pregnancy or even before pregnancy in this large number of specific population groups. It is the first time to find that the weight index before pregnancy can affect the relationship between weight gain and birth weight of newborns during pregnancy. Methods: a retrospective study of 3772 pregnant women in China was conducted. They were 18.5 kg / m2 in low body weight group, 18.5 kg / m ~ 2 in normal body weight group, 24.0 / 27.9 kg / m ~ 2 in hyperrecombination group and 27.9 kg / m ~ 2 in obese group respectively. The difference of birth weight of newborns between these four groups was compared, and the pregestational body mass index (PMI) was studied by multivariate analysis. Relationship between weight gain during pregnancy and birth weight of newborns. Conclusion: there is a positive correlation between maternal weight gain and weight gain during pregnancy (Table 2, extreme weight gain index and weight gain during pregnancy). The risk of abnormal neonatal birth weight (Table 3); the impact of weight gain during pregnancy on neonatal birth weight may also be affected by the preconception mass index (Table 2. For Chinese women, Existing guidelines for weight gain during pregnancy do not seem to be appropriate (fig. 2).
