【摘要】 对101名正常孕妇孕期营养摄取情况与婴儿出生体重的关系进行了探讨。结果表明,孕妇膳食中蛋白质、钙、核黄素和视黄醇的摄入量均较供给量标准低,孕中、后期尤其明显,而孕中、后期热能、脂肪,硫胺素、核黄素和尼克酸的摄入量又较孕初期显著增加。经单相关和逐步回归分析,婴儿出生体重与母亲膳食中热能、蛋白质、脂肪、糖类、铁、钙和核黄素的摄入量呈显著正相关。随着母亲孕期营养素摄入量的增加,婴儿出生体重也有逐步增大的趋势。孕妇在孕中、后期热能摄入为2400—2500kcal/天时,其婴儿出生体重较为适宜。增加孕妇膳食中蛋白质、钙和核黄素含量的问题有待解决。更多还原

【Abstract】 A nutritional survey of 101 uncomplicated primigravidas and the relationship between maternal diet and infant birth weight were investigated. The maternal intake of protein, calcium, riboflavin and retinol during the pregnancy was lower than the amount that RDA suggested especially in the 2nd and 3rd trimesters. The intake of calories, fat, thiamine, riboflavin and nicotinic acid in the 2nd and 3rd trimesters were increased in compa-rision with the 1st. The correlation and stepwise regression analysis indicated that maternal intake of calories, protein, fat, carbohydrate, iron, calcium and riboflavin during pregnancy was significantly correlated to the birth weight.更多还原
