【摘要】 方法：试验分为三组：单纯补锌组（Ｚ），同时补锌＋微量营养素组（Ｚ＋Ｍ），补微量营养素组（Ｍ）。结果：试验前发锌平均含量为２．２８±０．７４μｍｏｌ／ｇ，低于正常值下限共２４人，占受试总人数的２２．２２％。发锌含量与智商呈显著正相关（ｒ＝０．２２９，Ｐ＜０．０５，ｎ＝１０８）。补充试验后三个组发锌变化无显著性差别。Ｚ＋Ｍ组和Ｍ组智商，认知功能的改善好于Ｚ组，Ｚ＋Ｍ组和Ｍ组的差别无统计学意义。膝高的增长值Ｚ＋Ｍ组高于Ｍ组和Ｚ组，Ｍ组高于Ｚ组。结论：受试儿童中锌缺乏并不占主要地位，其他微量营养素的缺乏更应受到重视。同时补充锌和微量营养素可以改善儿童的智能发育，并能促进体格发育。更多还原

【Abstract】 Before　and　after　zinc　and　micronutrients　supplement　the　changes　of　intelligence　and　growth　in 108 healthy　children　aged　7-8yrs　were　studied.The　children　were　randomly　divided　into 3 groups:zinc　supplement(Z),zinc+micronutrients　supplement(Z+M),and　micro-nutrients　supplement(M).Before　the　supplements,hair　Zn　content　of　children　was 2.28±0.74μmol/g　and 22.22%　of　the　hair　Zn　content　was　lower　than　1.69μmol/g.　There　was　a　positive　correlation　between　intelligence　quotient(IQ)　and　hair　Zn　content.After　supplement,there　were　no　significant　changes　among　the 3 groups　on　hair　Zn　content.The　changes　of　IQ　and　cognition　in　Z+M　group　and　M　group　were　significantly　higher　than　Z　group,and　there　was　no　significant　difference　between　Z+M　group　and　M　group.The　change　of　knee　height　in　Z+M　group　was　markedly　higher　than　M　group　and　Z　group,while　M　group　was　significantly　higher　than　Z　group. The　results　demonstrated　that　zinc　deficiency　might　not　be　the　main　factor　that　affects　the　intelligence　and　growth　of　children,perhaps　other　micronutrients　deficiency　should　be　paid　more　attention.The　simultaneous　supplement　of　zinc　and　micronutrients　may　promote　the　intelligence　and　growth　of　children.更多还原
