孕期体重不同增长水平与妊娠结局的相关性研究

Correlation research of different growing levels of pregnancy weight on pregnancy outcome

目的探讨不同孕期体重增长水平与妊娠结局的相关性。方法选取淄博市三所三甲医院2016年11月-2017年3月住院分娩单胎活产且产检资料完整的1 200例孕妇,采用自制调查问卷收集孕妇的临床资料,并追踪妊娠结局。采用单因素,Logistic多因素回归等统计分析方法进行统计分析。结果孕早期体重增长(2.32±2.51)kg增加患GDM的风险,影响最为显著(OR=4.238,95%CI:1.559~6.260);孕中期体重增长(9.05±2.99)kg增加妊娠期高血压疾病的发生风险(OR=1.123,95%CI:1.029~1.226);孕中期体重增长(9.01±3.13)kg增加发生新生儿出生体重异常的风险(OR=2.979,95%CI:1.925~5.171)。结论不同孕期增重水平与妊娠结局的相关性各不相同,因此,对于孕期各阶段的体重增长都应给予科学的监测。

Objective To explore the correlation between weight gain and pregnancy outcomes.Methods Totally 1 200 hospitalized pregnant women were extracted from three hospitals in Zibo from November 2016 to March 2017,with single live births and complete prenatal inspection data.Self-designed questionnaire was used to collect the basic information of the pregnant women and track the pregnancy outcome.Single factor and logistic multifactor regression methods were used for statistical analysis.Results Early pregnancy weight gain（2.32±2.51）kg increased the risk of GDM,with the most significant effect（OR=4.238,95% CI：1.559~6.260）;mid pregnancy weight gain（9.05±2.99）kg increased the risk of gestational hypertension disease（OR=1.123,95% CI：1.029~1.226）;mid pregnancy weight gain（9.01±3.13）kg increased the risk of abnormal birth weight（OR=2.979,95% CI：1.925~5.171）.Conclusion The correlations of different levels of weight gain during pregnancy and pregnancy outcome are different,therefore,scientific surveillance should be paid to the weight gain in every stage of the pregnancy.
