孕前肥胖及孕期体重增长过度与妊娠期并发症及分娩结局的关系探讨

Relationship of Progestation Obesity and Excess Weight Gain during Pregnancy with Pregnancy Complication and Delivery Outcome

目的:探讨孕前肥胖、孕期体重增长过度孕妇妊娠期并发症的发生以及其分娩结局的关系。方法:测量2236例足月单胎初产妇孕前的身高、体重和孕期体重增长情况,计算孕前体重指数,并分别观察肥胖孕妇的妊娠期并发症、分娩方式、产程以及产后出血、新生儿窒息、巨大儿发生情况。结果:①孕前肥胖及孕期体重增长过度的孕妇妊娠期糖尿病、妊娠期高血压疾病以及早产的发生率与对照组比较差异有显著性;②孕前肥胖及孕期体重增长过度孕妇总产程、产程异常发生率、剖宫产率、产钳助产率、巨大儿和新生儿窒息的发生率以及围生儿死亡率与对照组比较差异有显著性或非常显著性。结论:孕前肥胖及孕期体重增长过度对孕产妇和新生儿均产生不利影响,增加了妊娠期、分娩期并发症和增高了难产发生率。

Objective：To determine the relation of progestational body mass index （BMI） and excess weight gain during pregnancy with pregnant complication and delivery outcome. Methods：2236 primiparas with full-term single birth were reviewed their progestational boca. height, body weight and increment of weight gain during pregnancy. The progestational BMI was calculated,the complication,delivery mode, birth process, postpartum hemorrhage, neonatal asphyxia, and macrosomia were investigated. Results： There was significantly higher prevalence of gestational diabetes mellitus （GDM）, pregnant-induced hypertension, preterm labor in women with progestational obesity and excess weight gain dudng pregnancy. And in these women, there were higher prevalence of delayed total stage of labor,abnormal birth process,CS rote, assisted-labor by obstetrical forceps, macrosomia and neonatal asphyxia and pednatal death rate.Conclusions：The progestational obesity and excess weight gain during pregnancy have adverse influence on pregnant women and neonatus through increasing prevalence of pregnant complication and dystocia.
