The relationship of maturity, age, race, sex and income level to dietary intake and body stores of iron, as indicated by percent of transferrin saturation, was studied in healthy adolescents. Maturity rating, sex, and race were significant. Level of family income was not a significant factor. Both boys and girls increase the intake of iron as they mature, boys more than girls, and white adolescents slightly more than their black counterparts. Range of intakes was large, and there was no significant correlation between quantity of dietary iron and the percent of transferrin saturation. Norms for dietary intake of iron and percent of transferrin saturation, based on sex, race, and maturity, are presented for use by physicians and nutritionists.
在健康青少年中，研究了成熟度、年龄、种族、性别和收入水平与饮食中铁摄入量以及转铁蛋白饱和度所表明的体内铁储存之间的关系。成熟度评级、性别和种族具有显著影响。家庭收入水平不是一个显著因素。男孩和女孩随着成熟都会增加铁的摄入量，男孩增加的量比女孩多，白人青少年比黑人青少年略有增加。摄入量范围很大，饮食中铁的摄入量与转铁蛋白饱和度百分比之间没有显著相关性。本文给出了基于性别、种族和成熟度的饮食中铁摄入量和转铁蛋白饱和度百分比的标准，供医生和营养师使用。
