摘要
目的：对孕妇进行个体化营养指导控制新生儿出生体重，并分析对围产儿结局的影响。方法：根据《中国居民膳食指南2007》，使用围产营养管理系统软件制定营养指导方案进行孕期个体化营养指导，分析孕前体重指数（BMI）、孕晚期BMI、孕期增重、新生儿体重、剖宫产率、产钳助产率、产后出血率。结果：①营养指导组晚孕期BMI、孕期增重低于对照组（P〈0．05）。②营养指导组的新生儿出生体重低于对照组（P〈0．05）；营养指导组中新生儿出生体重2500—3500g组比例高于对照组（P〈0．01）。③营养指导组的剖宫产率、产钳助产率均低于对照组（P〈0．05）。④新生儿出生体重2500—3500g组剖宫产率、产钳助产率、产后出血率低于3500～4000g组及≥4000g组（P〈0．01）。结论：通过孕期个体化营养指导，将孕妇体重指数、孕期体重增加及新生儿出生体重控制在合理范围内，有助于降低剖宫产率，改善新生儿分娩结局。
Objective： To control neonatal birth weight by conducting individualized nutrition guidance among pregnant women, and analyze the impact on outcome of perinatal infants. Methods： According to the Dietary guidelines of Chinese in 2007, perinatal nutri- tional management software was used to formulate nutrition guidance and provide individualized nutrition guidance during pregnant period~ body mass index （ BMI）, BMI during the third trimester of pregnancy, body weight gain during pregnancy, neonatal weight, cesarean section rate, forceps delivery rate and incidence rate of postpartum hemorrhage were analyzed. Results ： BMI during the third trimester of pregnancy and body weight gain during pregnancy in nutrition guidance group were statistically significantly lower than those in control group （P 〈 0.05 ） . Neonatal birth weight in nutrition guidance group was statistically significantly lower than that in control group （ P 〈 0.05 ） ; the pro- portion of neonates with birth weight at 2 500 - 3 500 g in nutrition guidance group was statistically significantly higher than that in control group （P 〈 0. 01 ） . Cesarean section rate and forceps delivery rate in nutrition guidance group were statistically significantly lower than those in control group （P 〈 0. 05 ） . Cesarean section rate, forceps delivery rate and incidence rate of postpartum hemorrhage in neonates with birth weight at 2 500 -3 500 g were statistically significantly lower than those in neonates with birth weight at 3 500 -4 000 g and I〉4 000 g （P 〈0. 01 ） . Conclusion： The maternal body mass index, weight gain during pregnancy and neonatal birth weight are controlled within reasonable extents after individualized nutrition guidance during pregnant period, the guidance is helpful to reduce cesarean section rate and improve neonatal birth outcome.
