Iron stores were assessed by measurement of serum ferritin in a population survey comprising 436 randomly selected urban Danish schoolchildren (219 boys, 217 girls) 7 to 17 years old. Median ferritin values were similar in boys and girls 7 to 13 years old, while 14- to 17-year-old boys had significantly higher values than girls of similar age (p < 0.0001). Boys had stable median ferritin values from 7 to 15 years of age, after which a significant rise was found from 16 to 17 years of age (p < 0.01). Girls had unchanged median ferritin values from 7 to 11 years of age, after which a significant decrease was found from 12 to 17 years of age (p < 0.01). The frequencies of low ferritin values < 16 micrograms/l (indicating absent iron stores) were: Children 7 to 11 years, 1.0%. Boys 12 to 15 years, 4.5%; 16 to 17 years, 0%. Girls 12 to 15 years, 7.6%; 16 to 17 years, 16.7%. Ferritin levels in the reported 1986 survey were significantly higher than those obtained in a similar survey in the same area in 1979. The results indicate an overall increase in iron stores in Danish schoolchildren and adolescents during 1979-1986, possibly due to an increase in the consumption of meat, and in the use of vitamin-mineral supplements containing iron.
在一项针对436名年龄在7至17岁之间随机挑选的丹麦城市学童（219名男孩，217名女孩）的人群调查中，通过测量血清铁蛋白来评估铁储备情况。7至13岁的男孩和女孩的铁蛋白中位数相似，而14至17岁的男孩铁蛋白值显著高于同龄女孩（p<0.0001）。男孩在7至15岁时铁蛋白中位数稳定，之后在16至17岁时出现显著上升（p<0.01）。女孩在7至11岁时铁蛋白中位数不变，之后在12至17岁时出现显著下降（p<0.01）。铁蛋白值<16微克/升（表明无铁储备）的频率为：7至11岁儿童为1.0%。12至15岁男孩为4.5%；16至17岁为0%。12至15岁女孩为7.6%；16至17岁为16.7%。1986年报告的调查中铁蛋白水平显著高于1979年在同一地区进行的类似调查中的水平。结果表明，1979 - 1986年期间丹麦学童和青少年的铁储备总体有所增加，这可能是由于肉类消费量增加以及含铁血维生素 - 矿物质补充剂的使用增加所致。
