目的评价妊娠期体重增加对河南地区孕妇妊娠结局的影响。方法将在郑州大学第三附属医院产检并分娩的1650名单胎孕妇,按孕期体重增加分为3,组:低体重增加组(<7kg),正常体重增加组(7～16kg),高体重增加组(>16kg),逻辑回归校正混杂因素后评价妊娠结局。结果孕期体重增加过度增加了妊娠期高血压疾病、妊娠期糖尿病、剖宫产、胎儿宫内窘迫以及出生大于胎龄儿的风险,但降低了小于胎龄儿出生的风险。孕期体重增加不足降低了多数不良妊娠结局的发生率但是增加了小于胎龄儿出生的风险。结论妊娠期体重增加异常和很多不良妊娠结局有关,通过宣传教育将孕期体重增加控制在适度范围有利于改善不良妊娠结局的发生率。
Objective To evaluate the effect of gestational weight gain on pregnancy outcome in pregnant women in Henan Province. Methods A total of 1650 singleton pregnant women who were seized and delivered at the Third Affiliated Hospital of Zhengzhou University were divided into three groups according to weight gain during pregnancy: group with low weight gain (<7kg), group with normal weight gain (7 ~ 16kg) Group (> 16kg), logistic regression to correct for confounding factors after the evaluation of pregnancy outcomes. Results Excessive weight gain during pregnancy increased the risk of gestational hypertension, gestational diabetes, cesarean section, fetal distress and birth greater than gestational age, but reduced the risk of being born less than gestational age. Insufficient weight gain during pregnancy reduces the incidence of most adverse pregnancy outcomes but increases the risk of being born less than gestational age. Conclusions Abnormal weight gain in pregnancy is related to many unfavorable pregnancy outcomes. Controlling the weight gain during pregnancy through a publicity and education program is conducive to improving the incidence of adverse pregnancy outcomes.
