孕期体重情况与巨大胎儿的关系

Effect of Weight During Pregnancy on Macrosomia

目的探讨孕产妇孕前BMI以及孕期体重增长对发生巨大儿的影响,为减少巨大儿发生率提供相关依据。方法选取300例巨大儿及300例正常体重新生儿病例,记录母亲的孕前体重、分娩前体重、孕期体重增长情况,计算母亲的孕前BMI、孕期增重程度,分析孕妇体重变化情况与发生巨大儿的关系。结果病例组孕前BMI、孕期增重与对照组比较差异有显著性意义(P<0.05)。孕前BMI(OR=1.242,95%CI:1.156~1.336)、孕期增重过多(OR=2.177,95%CI:1.334~3.552)是发生巨大儿的危险因素。结论巨大儿的发生与母亲孕前BMI、孕期增重过多密切相关。

Objective To investigate the influence of maternal BMI before pregnancy and weight gain during pregnancy on macrosomia,so as to provide relevant basis for reducing the incidence of macrosomia.Methods 300 cases of macrosomia and 300 cases of normal weight neonates were selected to record the weight before pregnancy,the weight before delivery and the weight gain during pregnancy.The weight gain before pregnancy and weight gain during pregnancy were calculated,and the relationship between the weight change of pregnant women and the occurrence of macrosomia was analyzed.Results BMI before pregnancy and weight gain during pregnancy in the case group were significantly different from those in the control group(P<0.05).Pre-pregnancy BMI(OR=1.242,95%CI:1.156~1.336),excessive weight gain during pregnancy(OR=2.177,95%CI:1.334~3.552)were risk factors for the occurrence of macrosomia.Conclusion The occurrence of macrosomia is closely related to BMI before pregnancy and excessive weight gain during pregnancy.
