摘要
目的:研究孕妇孕晚期营养素摄入与新生儿出生体重的关系。方法:调查宫内发育迟缓(IUGR)组、巨大儿组和正常儿组孕妇孕晚期连续3日营养素摄入量,并对孕晚期营养素摄入量及父母身高体重等因素和新生儿出生体重作相关性检验和多元回归分析。结果:孕晚期巨大儿组热能摄入、碳水化合物、蛋白质、锌、硒摄入量明显高于正常儿组(P<0.05),IUGR组蛋白质、硒、核黄素、胆固醇、动物性蛋白、动物性脂肪、动物性维生素A、肉禽鱼来源铁、动物性来源热能的摄入量明显低于正常儿组(P<0.05),而钙的摄入量明显高于正常儿组(P<0.05)。巨大儿组孕妇身高、孕前体重、产妇实足年龄均显著高于正常儿组(P<0.05);IUGR组的胎龄和配偶体重明显低于正常儿组(P<0.05)。对影响新生儿体重的上述独立因素作多元逐步回归分析,得到方程:Y(出生体重)=-7079.359+16.22X1(蛋白质)+30.78X2(孕前体重)+25.85X3(胎龄);R2=0.454。结论:孕晚期蛋白质摄入量、母亲孕前体重、胎龄对新生儿出生体重有显著影响。
Objective： To learn the effect of nutrient intake in the 3rd trimester pregnancy on infant birthweight. Methods： A comparision study was carried out based on a dietary survery on IUGR （Intrauterine Growth Retardation） group （n = 21）, macrosomia group（n = 20） and normal group（n = 45） about the intake of daily energy and nutrient in the 3rd trimester of pregnancy, and relative analyses was made for the relationship among nutrient intake in the 3 d trimester, parent＇s status and infant birthweight. Results： The intake of energy, carbohydrates, protein, zinc and selenium in macrosomia group was obviously higher than that in the normal group;the intake of protein, selenium, riboflavin, cholesterol and protein,fats,vitamin A from animals, iron from animals , energy from animals in IUGR group was significantly lower than that in the normal group, but the intake of the calcium was higher than that in the normal group.According to multiple regression the equation was set ： Y（hirth weight）=-7079.359＋16.33X1（the intake of protein in the 3rd trimester）＋30.78X2（Pre-pregnaney weight）＋25.85X3（gestational agp）,R^2=0.454. Conclusion： Protein intake in the 3 d trimester, pre-pregnancy weight and gestational age are strong predictors of infant birthweight.
