孕早期体重指数与孕期体重增长对母婴健康的影响

目的：探讨孕早期体重指数（BMI）及孕期体重增长情况对母婴健康的影响，为制定孕期体重增长正常标准提供依据。方法：根据孕早期体重指数和孕期体重增长情况将研究对象分别进行分组，比较不同组间情况对母婴健康的影响。结果：孕早期不同的BMI组间和孕期体重增长不同分组间妊娠期高血压疾病、妊娠期糖尿病、分娩方式、新生儿窒息、产后出血和巨大儿发生率的差别均有统计学意义（均P〈0．05）。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。

Influence of BMI at early pregnancy and weight gain during pregnancy on the health of maternal and newborn

Objective:To explore the influence of BMI at early pregnancy and weight gain during pregnancy on the health of maternal and newborn,and to provide the basis for establishing standard of weight gain during pregnancy.Methods:All cases were divided into different groups according to BMI at early pregnancy and weight gain during pregnancy,and were compared the effect on maternal and child health.Results:Compared with the status in groups at weight gain stage,the incidence of pregnancy-induced hypertension(PHI),gestational diabetes,delivery mode,neonatal asphyxia,postpartum hemorrhage and macrosomia had significant difference in groups at early pregnancy stage(P<0.05).Conclusion:The pre-gestational obesity and excess weight gain during pregnancy have adverse influence on pregnant women and neonatus,and increase the prevalence of pregnant complication and dystocia.
