测定了中山地区 2 2 2例厌食儿及 1 65例健康儿发锌、铁、铜、钙含量。结果显示 ,厌食儿发锌含量明显低于健康儿 ,P <0 0 1 ;发钙偏低 ,0 0 5>P >0 0 1 ;发铁、发铜含量基本正常 ,两组间无显著性差异。故提示厌食是缺锌的最早症状之一。缺锌年龄以 1～ 3岁为首 ,其次是 3～ 6岁。同时两组间Cu/Zn比值进行比较 ,结果表明厌食组明显高于健康组 ,P <0 0 1 ,说明体内微量元素变化以锌明显 ,Cu、Zn含量呈负相关。对于疾病的预防和治疗有指导性价值 The contents of zinc, iron, copper and calcium in 225 cases of anorexia and 165 healthy children in Zhongshan district were measured. The results showed that the content of zinc in anorexia children was significantly lower than that in healthy children (P <0.01); the calcium content was low (0 0 5> P> 0 0 1); the contents of iron and copper were basically normal, difference. It is suggested that anorexia is one of the earliest symptoms of zinc deficiency. Zinc-deficient age to 1 to 3 years old, followed by 3 to 6 years old. At the same time, the Cu / Zn ratio was compared between the two groups. The results showed that the anorexia group was significantly higher than the healthy group (P <0.01), indicating that the changes of trace elements in the body were markedly marked with zinc and negative correlation with Cu and Zn contents. For the prevention and treatment of diseases have guiding value
