①目的了解儿童锌的营养状况，并进一步研究锌与智力的关系。②方法对１０８名城市学龄儿童进行发锌含量的测定，并应用中国－比内智力量表对上述儿童进行智商测定。③结果受试儿童发锌含量为２．１５±０．７４μｍｏｌ／ｇ，其中低于正常值下限者共３２名，占受试总人数的２９．６３％．发锌含量与智商呈正相关（ｒ＝０．２２９，Ｐ＜０．０５）。④结论部分儿童存在锌缺乏，缺锌会对儿童智力产生一定的影响。
①Objective To understand the nutritional status of children with zinc and further study the relationship between zinc and intelligence. Methods The determination of zinc content in 108 urban school-age children was carried out. The IQ of the above-mentioned children was measured by using the China-Liberia Intelligence Scale. ③ Results The zinc content of the children tested was 2.15 ± 0.74μmol / g, of which 32 were below the lower limit of normal, accounting for 29.63% of the total. Hair zinc content and IQ were positively correlated (r = 0.229, P <0.05). ④ Conclusion Some children have zinc deficiency, zinc deficiency will have a certain impact on children’s intelligence.
