孕妇妊高征发生情况及新生儿出生体重调查

目的调查孕妇孕前体质指数、孕期体重增加情况与妊高征及新生儿出生体重的关系，为降低高危妊娠、巨大儿、低体重儿的发生率提供依据。方法测量623例初产妇孕前体质指数和孕期体重增加情况，并分析妊高征、巨大儿、低出生体重儿的发生情况。结果孕妇孕前体质指数过高则妊高征和巨大儿的发生率明显升高；孕前体质指数过低则低出生体重儿的发生率明显升高；孕妇怀孕期间体重增加过多，则妊高征和巨大儿的发生率明显升高；体重增加过少则低出生体重儿的发生率明显增高，差异均有统计学意义（P〈0．05）。结论孕妇孕前体质指数和孕期增重情况与妊高征及新生儿出生体重有关。要重视母亲孕前体重及孕期体重变化，实现优生优育。

Investigation on pregnancy-induced hypertension of pregnant women and birth weight of neonatus

Objective To explore the relations between pre-pregnancy body mass index,weight gain during pregnancy with pregnancy-induced hypertension and birth weight,in order to reduce the incidence of pregnancy-induced hypertension,fetal macrosomia and Low birth weight babies.Methods Monitored the pre-pregnancy body mass index and pregnancy weight gain of 623 uniparas,and analysed the incidence of pregnancy-induced hypertension syndrome,fetal macrosomia and low birth weight babies.Results If the pre-pregnancy body mass index was too high,the incidence of pregnancy-induced hypertension and fetal macrosomia would be higher;the under weight mothers were more likely to have low birth weight babies.If the weight gain between pregnancy was to high,the incidence of fetal macrosomia and pregnancy-induced hypertension would be higher,and low birth weight was more likely occurred in babies whose mother with pregnancy weight gain too less.Conclusion There are relationship between pre-pregnant body mass index,weight gain during pregnancy and the occurrence of pregnancy-induced hypertension and the birth weight of neonates,so we should pay more attention to variations of pregnancy weight,realize eugenic and superior nurture.
