Objective To investigate the effect of improving and monitoring pregnancy nutrition for pregnancy outcomes.Methods Four hundred and sixteen pregnant women were selected for the study to monitor the impact of its nutrient intake on pregnancy out-comes.Results The incidence of huge children's group was significantly higher than that of the study group(P<0.05),and the inci-dence of pregnancy-induced hypertension (0.48%)of the study group was significantly lower than that of the control group (3.85%) (P<0.05).Prenatal weight,weight gain,prenatal BMI of huge children'mother were significantly higher than those of normal weight children,low birth weight children (P<0.05);huge children's mothers'energy and protein intake was significantly higher than those of normalweightchildren,lowbirthweightchildren's(P<0.05).Conclusion If the energy and nutrient intake during pregnancy was unreasonable,pregnant high pressure and other adverse pregnancy outcomes may develop.Maternal nutrition surveillance should be car-ried out to reduce the incidence of adverse pregnancy outcomes.%目的 监测与评估孕妇孕期营养状况,制定适合孕妇具体情况的膳食指导,分析改善孕期营养状况对妊娠结局改善的价值.方法 选取接受孕期营养指导的416例孕妇为研究对象,随机数字表法分为观察组和对照组,各208例,监测其营养素的摄入情况与妊娠结局的相关性.结果 对照组的巨大儿的发生率明显高于观察组(P<0.05);而观察组的妊高症的发生率(0.48%)明显低于对照组(3.85%)(P<0.05);巨大儿组母亲的产前体质量、体质量增长、产前BMI明显高于正常体质量儿、低体质量儿(P<0.05);巨大儿组母亲的能量、蛋白质摄入量明显高于正常体质量儿、低体质量儿(P<0.05);有妊高症组的摄入量明显高于无妊高症组(P<0.05);有妊娠期高血糖组的摄入量明显高于无妊娠期高血糖组(P<0.05).结论 孕期的能量、营养素的摄入过剩可能会导致出生体质量儿、巨大儿、妊高压等不良妊娠结局,孕妇改善营养状况有利于减少不良妊娠结局的发生.
