孕前体重指数及孕中期体重管理对妊娠孕妇体重增加情况及巨大儿的影响

Effect of Pregestational Body Mass Index and Pregnancy Weight Management on Maternal Weight Gain and Fetal Macrosomia

目的:观察孕前体重指数及孕中期体重管理对妊娠孕妇体重增加情况及巨大儿的影响。方法:选取2013年3月~2016年2月某院收治的400例单胎初产妇为研究对象,采用随机数字表法将其分为研究组和对照组,对照组实施常规产科检查,研究组给予孕前体重指数及孕中期体重管理,对两组研究后妊娠孕妇体重增加情况及妊娠结局的影响进行观察比较。结果:研究组孕期体重增重范围、中孕和晚孕期体重增长速度分别均较对照组显著小,均具有统计学意义(P<0.05);研究组剖宫产、巨大儿发生率均较对照组显著低,均差异显著(P<0.05)。结论:孕前体重指数及孕中期体重管理可较好调控妊娠孕妇体重增加情况,并有效降低巨大儿及剖宫产发生率。

Objective：To observe the effect of pregestational body mass index and pregnancy weight management on maternal weight gain and fetal macrosomia.Methods：400 single birth primiparae admitted in a hospital from March 2013 and February 2016 were selected and divided into study group and control group by the random number table method.The control group received routine obstetric examination,and the study group received pregestational body mass index and pregnancy weight management,then the weight gain situation and pregnancy outcomes were observed and compared between the two groups.Results：The range of weight gain,and the weight gain speed at middle and late pregnancy of study group were significantly lower than those of control group,which the differences were statistically significant（P〈0.05）;The incidence rates of cesarean section and fetal macrosomia of study group were significantly lower than those of control group,with significant differences（P 〈0.05）.Conclusion：Pregestational body mass index and pregnancy weight managemen can better control maternal weight gain,and effectively reduce the incidence of macrosomia and cesarean section.
