妊娠前不同体重指数与围产结局的关系研究

Effect of prepregnancy body mass index categories on obstetrical and neonatal outcomes

目的研究妊娠前不同体重指数对围产结局的影响。方法回顾性分析2005~2007年在我院分娩的单胎妇女238例,按妊娠前体重指数(BMI)分为BMI在19.8~23.9的正常BMI组、BMI 24~27的高BMI组和BMI≥27的肥胖组。新生儿体重≥4000g为巨大儿。比较正常BMI组、高BMI组和肥胖组的围产结局。结果全部资料共有238例,其中正常BMI组182例,高BMI组117例,肥胖组56例,巨大儿的发生率分别为10.4%、19.6%、28.6%,妊娠期高血压病、妊娠期糖尿病、羊水过多的风险随妊娠前BMI增加而上升,早产、剖宫产、新生儿病率的发生率亦随妊娠前BMI增加而升高,差异有显著性。结论妊娠前异常的母亲体重指数高度影响巨大儿的发生率;随妊娠前BMI增加不良围产结局的风险增加。

Objective:To examine the association between body mass index(BMI) and obstetrical and neonatal outcomes.Methods:We conducted a cohort study comparing prepregnant BMI categories with obstetrical and neonatal outcomes using the Xuan Wu Hospital on all deliveries in 3 year period(2005-2007).Prepregnant BMI was categorized into normal(19.8~23.9),overweight(24~27),obese(≥27),Analysis was performed for three groups using normal BMI as the reference.Newborns weighting 4000 or heavier,were defined as macrosomic.Res...
