目的探讨个体化营养干预对孕妇孕期体质量增长及妊娠结局的影响。方法选取2013年6月-2014年1月于12 w前后在本院建卡的212例正常孕妇作为研究对象,2013年6月-2013年9月的124例设为对照组,2013年10月-2014年1月的88例设为研究组。对照组孕12 w开始接受常规产检和孕期健康教育讲座,研究组孕妇于建卡时（孕12 w前后）、孕22-24 w、孕32-34 w由专业营养师一对一进行面对面营养评价与营养指导,两组孕妇随访至分娩结束。比较两组孕妇孕期体质量增长、孕期并发症、分娩方式及围产儿结局变化情况。结果研究组孕妇孕期体质量增长、妊娠期糖尿病（gestational diabetes mellitus,GDM）发生率、剖宫产率明显低于对照组;研究组新生儿出生体重、巨大儿发生率明显轻于与低于对照组,两组比较,差异具有统计学意义（均P〈0.05）。结论由专业营养师进行个体化营养干预,可控制孕妇孕期体质量,降低妊娠期糖尿病发生率,改善妊娠结局,保障母婴健康。

英文摘要：

Objective To explore the effects of individualized nutrition intervention on body weight gaining and pregnant outcome in normal pregnant women. Methods Two hundred and twelve normal pregnant women admitted in our hospital before the12 th gestational week were divided into the observation group and the control group. Eighty-eight pregnant women admitted between October 2013 and January 2014 were assigned into the observation group and another 124 pregnant women admitted between June 2013 and September 2013 into the control group. The observation group was given nutrition assessment and nutritional guidance one by one and face to face by the nutritionist at three time points ： around the 12 thgestational week, between the 22 nd to 24 th gestational week,and between the 32 nd to 34 th gestational week. The control group was given regular antenatal visits and lectures during pregnancy.These two groups were followed up until delivery. The comparisons were down between the groups in terms of body weight gain and complications during pregnancy, delivery mode and the change of perinatal fetus outcome. Results In the observation group, the body weight gaining of the pregnant women during pregnancy, the incidence of gestational diabetes mellitus（GDM） and the cesarean section rate were significantly lower than those of the control group（all P 〈0.05）. The neonatal birth weight and the incidence of macrosomia were significantly lower than those of the control group（all P 〈0.05）. Conclusion Individualized nutritional intervention given by the nutritionist can control body weight gaining during pregnancy, decrease the incidence of GDM, improve the pregnancy outcome and ensure the maternal and child health.
