Serum ferritin concentrations were measured in 909 urban Danish schoolchildren (451 boys, 458 girls) 6 to 17 years old. The children had been randomly selected and served as an urban reference population. Geometric mean ferritin values were identical in boys and girls 6 to 15 years old, while 16- and 17-year-old boys had higher values than girls (P less than 0.01). There was a slight rise in mean ferritin values from 6 to 11 years, followed by a temporary fall during the subsequent adolescent growth period. Geometric mean ferritin values and significant differences were as follows: Children 6 to 11 years old (n = 335), 29 micrograms/l and adolescents 12 to 15 years old (n = 417), 26 micrograms (P less than 0.01): Adolescent boys 16 to 17 years old (n = 76), 32 micrograms/l and adolescent girls same age (n = 81), 24 micrograms/l (P less than 0.01). The frequencies of low ferritin values less than 10 micrograms/l (i.e. exhausted iron stores) were: Children 6 to 11 years old, 2.1%: Adolescents 12 to 15 years old, 5.0%: Adolescent boys 16 to 17 years old, 0.0%: Adolescent girls 16 to 17 years old, 11.1%. High ferritin values greater than 60 micrograms/l (i.e. large iron reserves) were observed in 6.2% of boys and 6.9% of girls.
对909名6至17岁的丹麦城市学童（451名男孩，458名女孩）进行了血清铁蛋白浓度测量。这些儿童是随机选取的，作为城市参考人群。6至15岁的男孩和女孩的铁蛋白几何平均值相同，而16岁和17岁的男孩铁蛋白值高于女孩（P<0.01）。铁蛋白平均值从6岁到11岁略有上升，随后在青春期生长阶段暂时下降。铁蛋白几何平均值及显著差异如下：6至11岁儿童（n = 335），29微克/升；12至15岁青少年（n = 417），26微克（P<0.01）；16至17岁青少年男孩（n = 76），32微克/升；同年龄青少年女孩（n = 81），24微克/升（P<0.01）。铁蛋白值低于10微克/升（即铁储备耗尽）的频率为：6至11岁儿童，2.1%；12至15岁青少年，5.0%；16至17岁青少年男孩，0.0%；16至17岁青少年女孩，11.1%。铁蛋白值高于60微克/升（即大量铁储备）的情况在6.2%的男孩和6.9%的女孩中观察到。
