摘要
目的:探讨孕期体重指数(BMI)与头位难产的关系.方法;将267例单活胎、头先露、孕足月(37～42周)、母身高≥150 cm之初产妇按BMI=0.17～0.24为正常组、BMI＜0.17为低重组、BMI＞0.24为超重组,比较3组孕妇头位难产率、巨大儿发生率、剖宫产率、产时宫缩乏力发生率、新生儿体重增加的情况.结果:超重组头位难产率、巨大儿发生率、剖宫产率、产时宫缩乏力发生率、新生儿体重增加显著高于低重组和正常组(P＜0.05,P＜0.01).结论:BMI与头位难产呈正相关,孕期控制体重及合理营养有助于减少头位难产的发生率.
Objective:To explore the relationship body mass index (BMI) during pregnancy and head presentation dystocia.Methods:267 cases of primiparas who have monozygotic pregnancy, head presentation, term pregnancy (37~42 W), height≥ 150 cm can were divided into 3 groups according to BMI, BMI=0.17~0.24 was normal group, BMI<0.17 was low weight group, BMI>0.24 was overweight group. Comparative analysis were made in the head presentation dystocia rate, the fetal macrosomia incidence rate, cesarean section rate, the newborn's body average weight.Results:5 Comparative analytic factors in overweight group were significantly higher than those in low weight group and normal group ( P<0.05,P <0.01).Conclusion:BMI during pregnancy was positively correlated with head presentation dystocia. Control weight and rational natrition during pregnancy are conducive reduce incidence of head presentation dystocia.
