中文摘要:
      目的 探讨母亲孕前BMI及孕期增重与学龄前儿童超重肥胖的关系。方法 2016年6-11月,以广州市4 303名3~5岁学龄前儿童为研究对象,根据WHO标准和中国成人肥胖标准分别判断儿童和母亲孕前体重状态,参照美国医学研究所孕期增重推荐值判断母亲孕期增重情况。应用多因素二分类非条件logistic回归模型和协方差分析母亲孕前BMI和孕期增重与学龄前儿童超重肥胖的关系。结果 矫正混杂因素后,logistic回归分析显示,母亲孕前超重肥胖的儿童发生超重肥胖的风险是母亲孕前体重正常儿童的1.820倍(OR=1.820,95% CI:1.368~2.422);与母亲孕期增重适宜的儿童相比,母亲孕期增重过度的儿童超重肥胖发生风险增加(OR=1.296,95% CI:1.007~1.667)。协方差分析结果也显示,母亲孕前体重超重肥胖和母亲孕期增重过度均增加儿童BMI Z值。根据母亲孕前BMI分为3组进行分层分析,结果显示,不同孕期增重组间儿童超重肥胖发生风险差异无统计学意义(P>0.05)。但与母亲孕前BMI适宜且孕期增重适宜组相比,母亲孕前超重肥胖且孕期增重过度组的儿童发生超重肥胖的风险增加(OR=1.574,95% CI:1.029~2.409)。结论 母亲孕前超重和孕期增重过度均增加学龄前儿童超重肥胖的风险,且母亲孕前超重较孕期增重过度对学龄前儿童超重肥胖发生的影响更大。
英文摘要:
      Objective To investigate the association of both maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) with childhood overweight and adiposity in preschool children. Methods A total of 4 303 preschool children aged 3-5 years were enrolled in our study during June and November 2016 in Guangzhou. Children defined as overweight and obesity were according to the criteria of WHO while weight status during maternal pre-pregnancy was using the China Adult Reference. Gestational weight gain was defined according to the Institute of Medicine guidelines. Results After adjusting the possible confounding factors, results from the logistic regression analysis showed that both maternal pre-pregnancy overweight and obesity would increase the risk for both childhood overweight and obesity (OR=1.820, 95%CI:1.368-2.422). The analysis of covariance results also showed that both maternal overweight and obesity before pregnancy and excessive maternal weight gain during pregnancy increased the BMI Z-score in children. Maternal GWG over the recommended level were associated with both the childhood overweight and obesity (OR=1.296, 95%CI:1.007-1.667). Joint associations of pre-pregnancy BMI and inappropriate GWG were also noticed in the study. Stratified analysis was conducted in three groups according to the pre-pregnancy BMI of the mothers. Result showed that there was no statistical difference in the risks of either overweight or obesity in children (P>0.05). However, when compared to mothers with adequate pre-pregnancy higher BMI and adequate GWG, under the combination of high pre-pregnancy BMI and excessive GWG, their adverse effects on childhood overweight and obesity were much higher (OR=1.574, 95%CI:1.029-2.409). Conclusions Both high pre-pregnancy BMI and inappropriate GWG were associated with greater BMI of their offspring. Pregnant women should follow the appropriate weight gain program and help their children to prevent from becoming obese.
