【摘要】 目的:了解孕期膳食结构对孕妇营养状况、新生儿出生体重、早产发生率的影响,为科学指导孕妇合理膳食,改善妊娠结局提供科学依据。方法:对2013年7月-12月在河南省妇幼保健院待产的160例孕妇进行营养问卷调查、体格检查,测量新生儿出生体重,应用秩和检验和秩相关分析的统计方法分析孕期膳食摄入情况对孕妇营养状况及新生儿发育的影响。结果:调查人群谷类及薯类、畜禽肉类、水产类、奶类及制品摄入不足比例高。足月分娩的孕妇,孕期坚果、大豆、畜禽肉类摄入量显著高于提早分娩孕妇(P<0.05)。畜禽肉类及水产类的摄入量与孕期增重呈正相关(P<0.05)。膳食结构与新生儿出生体重不具有统计学关联(P>0.05)。结论:部分孕妇膳食结构不合理,多种食物未达到或超过推荐摄入量。畜禽肉类、大豆及坚果类摄入量低与早产发生率高有关。孕妇畜禽肉类及水产类摄入量与孕期增重呈正相关。更多还原

【Abstract】 Objectives:To investigate the effects of maternal dietary pattern on pregnant woman nutritional status and the neonatal birth weight as well as the rate of pretenn delivery and provide scientific base for a better guidance on maternal nutrition and improve the birth outcome.Methods:The investigation was conducted in the Third Affiliated Hospital(also the hospital of women and children health) of Zhengzhou University from July to December,2013.The subjects were the women hospitalized for baby delivery in that hospital.The investigation included questionnaire of nutrition intake survey,maternal medical examination,neonatal birth weight.We analyzed the influence of meals situation on the pregnant woman and newborn using the statistical methods of Wilcoxon rank sum test and rank correlation.Results:A large number of pregnant women which we investigated consumed less meat,cereal and potatoes,aquatic product,milk compared to the standard amount.The women who gave full tenn delivery had significantly higher intake of soybean,nut,and meats than those gave pre-tenn delivery(P<0.05).The consumption of poultry meats and sea food were positively correlated with the weight gain gestation period(P< 0.05).The maternal dietary pattern had no significant influence on neonatal birth weight(P>0.05).Conclusions:The dietary pattern of part of pregnant women is not reasonable,variety of foods don’t meet or exceed the recommended intake.Maternal dietary pattern has impact on body weight gain during gestation period.More meat intake causes more weight gain.Maternal food intake might affect birth outcome.Pre-tenn delivery might be related with less nuts,bean,and meat intakes.更多还原
