孕期体重管理对控制足月新生儿体重及妊娠结局的影响

目的:探讨孕期体重管理对控制足月新生儿体重及妊娠结局的影响。方法:1 120例体重指数(BMI)≥24初产妇随机分为对照组及观察组,对照组只进行常规的产前检查,观察组接受个体化体重管理。观察两组新生儿体重、新生儿窒息及孕妇妊娠高血压、妊娠糖尿病、产程阻滞、产后大出血等情况。结果:观察组新生儿中巨大儿发生率明显低于对照组,差异有统计学意义(P<0.05);妊娠高血压、妊娠糖尿病、产程阻滞、新生儿窒息、产后大出血等不良妊娠结局的发生均显著低于对照组,差异有统计学意义(P<0.05);体重在3～3.5 kg新生儿其母体上述不良妊娠结局发生率最低(P<0.05)。结论:对孕妇采取孕期体重管理,控制新生儿体重在3～3.5 kg内有利于妊娠结局。

Effect of management of pregnancy weight on controlling neonate weight and pregnant outcome

Objective:To investigate the effect of management of pregnancy weight on controlling neonate weight and pregnant outcome.Methods:1 120 primiparas with body mass index(BMI)≥24 kg/m2 were randomly divided into control and observation groups.Primiparas in control group only underwent routine prenatal examination.Primiparas in observation group were received individual weight management.Then the newborn weight and the pregnancy outcome including hypertension of pregnancy,gestational diabetes mellitus,birth process block,neonatalasphyxia,postpartum hemorrhage of two groups were observed.Results:The incidence of macrosomia of observation group was significantly lower than that of control group(P<0.05).The incidence of hypertension of pregnancy,gestational diabetes mellitus,birth process block,neonatal asphyxia,postpartum hemorrhage were also lower than those of control group(P<0.05).Incidence of weight at 3-3.5 kg neonate' mother's above pregnancy outcomes were lowest(P<0.05).Conclusion:Neonate weight controlled 3-3.5kg by management of pregnancy weight is beneficial to pregnant outcome.
