摘　　要：目的 对宝鸡市城区儿童血清中5种微量元素的水平进行分析比较。方法采用博辉BH5100分析仪测定1161例儿童不同年龄组微量元素铜、锌、钙、镁和铁的含量，并对其结果进行统计学分析。结果男、女儿童间锌、镁、铁元素比较均无显著性差异（f分别为1．70、0．39、1．72，均P〉0．05），铜、钙元素比较有显著性差异（￡分别为2．58、2．35，均P〈0．05）。锌、铁含量随儿童年龄增长呈上升趋势（F分别为266．39、61．28，均P〈0．05），钙随年龄增长呈下降趋势（F=32．58，P〈0．05），铜、镁随年龄增长无明显波动（F分别为1．27、1．51，均P〉0．05）。微量元素缺乏比率的顺序依次为锌（43．76％）、铁（32．04％）、钙（5．25％）、铜（2．93％）、镁（0．09％）。微量元素过高比率的顺序依次为钙（2．15％）、镁（0．26％）、锌（0．17％），无高铁、高铜出现。低锌与低铁发生率随年龄增长递减（r铁=-0．74、r锌=-0．81，均P〈0．05），低钙发生率随年龄增长而递增（r钙=0．98，P〈0．05）。结论在宝鸡市城区的儿童保健工作中，应加强儿童锌和铁的补充，提倡从婴幼儿开始补充铁和锌，定期检查微量元素，合理补钙。Objective To detect serum levels of 5 trace elements of children in urban areas of Baoji city. Methods Serum levels of trace elements such as copper （Cu） , zinc （Zn） , calcium （Ca） , magnesium （Mg） and iron （Fe） of 1 161 children in different age groups were detected by using BHS100 biochemoanalyzer, then the results were analyzed statistically. Results There were no significant differences in serum levels of Zn, Mg and Fe between boys and girls in different age groups （t = 1,70, 0.39, 1.72 respectively, all P 〉 0.05）, but in serum levels of Cu and Ca there were significant differences （ t = 2.58, 2.35 respectively, both P 〈 0.05）. The serum levels of Zn and Fe of the children were increased with increase in age of the children （F = 266.39 and 61.28, both P 〈 0.05）, while the serum level of Ca of the children was decreased with increase in age of the children （F = 32.58, P 〈 0. 05 ）. With increase in age of the children, no significant fluctuations in serum levels of Cu, Mag were found （ F = 1.27 and 1.51, both P 〉 0.05）. The incidence rates of trace elements deficiencies were 43.76% （Zn）, 32.04% （Fe）, 5.25% （ Ca）, 2.93% （ Cu）, 0.09% （Mg） in order and the incidence rates of trace elements excessiveness were 2.15% （Ca） , 0.26% ） （Mg） and 0.17% （Zn） in order. No siderosis and hypercupremia were found. The incidence rates of hypozincemia and hypoironemia were gradually decreased with increase in age of the children （τFa = - 0.74, τZn =-0. 81 ,both P 〈0.05 ） , while the incidence rate of hypocalcemia was increased with increase in age of the children （ τCa = 0.98 ,P 〈 0.05）. Conclusion In child health work for those urban children in Baoji city, supplementation of trace elements such as zinc and iron should be strengthened and encouraged to start from beginning of infancy. Also, the children should be examined for serum levels of trace elements regularly and added calcium preperations reasonably.
