Iron intake and transferrin saturation in adolescents.
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.
