孕前体重及孕期体重增长对胎儿出生结局的影响

Influence of Prepregnancy Weight and Weight Gain During Pregnancy on Fetal Birth Outcomes

目的:研究孕期女性孕前体重及孕期体重增长对胎儿出生结局的影响。方法:选择2012年7月至2012年8月在卫生部北京医院产科常规查体的164例孕妇为研究对象,跟踪整个孕期,记录其孕前体重、产前体重、胎儿出生体重、胎儿出生身长、胎盘重、脐带长等指标。结果:孕前体重与胎盘重相关(t=2.89,P<0.05),孕前体重与胎儿出生体重相关(t=2.80,P<0.05);孕期体重增长与胎儿出生体重相关(t=2.34,P<0.05),孕期体重增长与脐带长度相关(t=3.05,P<0.05)。结论:合理的孕前体重及孕期体重增长对胎儿出生结局有利。

[Objective] To study the influence of prepregnancy weight and pregnancy weight gain during pregnancy on fetal birth out- comes. [Method] We chose 164 pregnant women who did routine inspection in Beijing Hospital from July to August in 2012 and tracked the whole pregnancy, recorded their prepregnancy weight, prenatal weight, fetal birth weight and length, weight of placenta, umbilical cord length, etc. [Result] Prepregnancy weight was correlated with placental weight （t = 2. 89, P 〈 0. 05） and fetal birth weight （ t = 2. 80, P 〈 0. 05 ） . Weight gain during pregnancy was correlated with fetal birth weight （ t = 2. 34, P 〈 0. 05 ） and the cord length （ t = 3.05, P 〈 0. 05 ） . [Conclusion] The reasonable prepregnancy weight and weight gain during pregnancy was helpful to fetal birth outcomes.
