摘　　要：目的:观察矮小身材儿童全血锌、铜、铁、钙、镁含量的变化并进行分析。方法:采用火焰原子吸收法检测88例矮小儿童的全血锌、铜、铁、钙、镁含量。结果:矮小儿童的低血锌、低血铜、低血铁、低血钙发生率分别为55.68%、28.41%、51.14%和71.59%,血镁均在正常范围内,未见5种金属元素升高者。低血锌、低血铜、低血铁发生率分别在家族性矮小、GHD、体质性等原因引起的矮小儿中最高,而低血钙率在3组矮小儿间无明显差别。结论:矮小身材儿童体内存在不同程度的锌、铜、铁、钙缺乏,且低血锌、低血铜、低血铁发生率在不同病因中存在差异,故对矮小儿童要注意适当补充锌、铜、铁、钙等金属元素。Objective： To observe and analyse the change of blood zinc, copper, iron, calcium, magnesium level in microsomia children. Methods： Blood zinc （Zn） , copper （Cu） , iron （Fe） , calcium （Ca） and magnesium （Mg） of 88 children with short stature were determined by atomic absorption spectrophotometer. Results： The incidence of the microsomia children with lowered blood Zn, Cu, Fe and Ca was 55. 68%, 28. 41%, 51.14% and 71.59% respectively, while blood Mg values of all the cases were normal, there was no case which five blood elements were higher than the normal range. The highest incidence of lowered blood Zn, Cu, Fe was in the cases with familial short stature, growth hormone deficiency and other short stature （including constitutional delay of growth, etc） respectively, while the incidence of lowered blood Ca was no significant differenceamong three groups. Conclusion： As there were lack of Zn, Cu, Fe and Ca in the microsomia children on some extent, and the incidence of lowered blood Zn, Cu, Fe was not same in the cases with various cause, Zn, Cu, Fe and Ca should be supplemented in microsomia children under doctor＇s instructions.
