巨大胎的发生与母体体重指数及糖耐量的关系

对我院初产分娩巨大胎的69例产妇和初产分娩正常作重的69例产妇的体重指数、血糖耐量及分娩方式等进行了分析．结果显示：分娩巨大胎的产妇孕20周及分娩前体重指数均较分娩正常体重儿的产妇高（P＜0．005），孕期体重的增长也明显增多（P＜0．005）；孕中期50gOGTT筛查中，前者阳性人数显著多于后者（P＜0.01）,诊断GDM者也显著多于后者；巨大胎组的分娩方式与正常体重儿组比较有显著差异；剖宫产率明显增多（P＜0.005）；新生儿窒息的发生率两组未见差异（P＜0.05）．巨大胎组中，孕20周母体体重过重者分娩方式与非过重者比较有显著性差异，剖宫产率亦明显增高（P＜0.01），提示：孕期母体体重指数过高及孕中期血糖耐量的降低与巨大胎的发生有关，孕期母体体重指数过高是巨大胎剖宫产率增高的原因之一。

Relationship of Macrosomia, BWI of Pregnant Woman and Glucose Tolerance

BWI of pregnant woman, glucose tolerance and style of delivery were analysed in 69 preg-nant women who delivered overwight babies and 69 pregnant women who delivered normal weightbabies in gestational 20 weeks and before delivering, the plasma level of glucose in the mother ofoverweight baby was high on 50g OGTT in the second trimester, cesarean delivery was also more frequentin mother of overweight baby. In macrosomia group, overweight women had high rate of cesarean delivery.The conclusion is that decreasing of glucose tolerance in second trimester has relationship with overweightfetus, that high BWI in pregnant wornan is one of the reasons of cesarean delivery in macrosomia.
