母亲孕前体重指数和孕期增重对母婴预后的影响

目的探讨孕前体重指数(BMI)和孕期增重与新生儿出生体重及妊娠结局的关系,为降低高危妊娠和巨大儿发生率及难产发生率提供依据。方法以BMI为标准分为低体重组、正常体重组和肥胖组,分析孕妇体重过度增重、巨大儿发生率、难产发生率以及体重指数与新生儿体重、分娩方式和孕期并发症的关系。结果3组间新生儿出生体重有明显差异,巨大儿发生率分别为5.00%、6.10%和11.96%,有统计学意义(P0.05)。孕期体重增重过重与新生儿体重成正相关(P0.05);肥胖组妊娠期糖尿病发病率明显增多,是正常组的3倍,且妊高征发病率明显增高。3组分娩方式、难产(剖宫产和产钳助产)的发生率比较,有非常显著性差异。结论肥胖组的巨大儿、妊娠期糖尿病和妊高征的发生率都高于正常体重组和低体重组,孕前BMI和孕妇体重过度增长与新生儿出生体重和妊娠结局有关。

The Influence on Maternal and Child Prognosis of Pre-pregnancy Bady Mass Index and Weight Gaining During Pregnancy

OBJECTIVE To investigate body mass index and body weight over pregnancy weight gain and neonatal birth weight and pregnancy outcome of the relationship between high-risk pregnancies and to reduce the incidence and great children provide the basis for the incidence of dystocia. METHODS The body mass index（BMI） as the standard group,analysis of excessive maternal weight,weight gain,a huge children incidence,the incidence of dystocia,as well as BMI and birth weight,mode of delivery,pregnancy complications. RESULTS The three groups had significant differences in birth weight,a huge incidence of children were 5.00%,6.10% and 11.96%,with statistically significant difference（P0.05） . Weight,excessive weight gain during pregnancy and birth weight was positively related（P 0.05）;Obese group significantly increased with gestational diabetes mellitus was 3 times the normal group,and the incidence of pregnancy-induced hypertension was significantly higher. Group 3 mode of delivery,obstructed labor（cesarean section and forceps delivery） compared the incidence,there are very significant differences. CONCLUSION The obese group and excessive weight gain during pregnancy were great children,pregnancy,the incidence of diabetes and pregnancy-induced hypertension is higher than normal weight and low body restructuring,pre-pregnancy body mass index and excessive growth of body weight and neonatal birth weight and pregnancy outcome related.
