摘　　要：目的　为探讨锌及其他微量元素对儿童智商 ,认知功能和生长发育的影响。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) ,补微理营养素组 (M)。结果　试验前发锌平均含量为 2 2 8±0 74 μmol/g ,低于正常值下限共 2 4人 ,占受试总人数的 2 2 2 2 %。发锌含量与智商呈显著正相关 (γ =0 2 2 9,P <0 0 5 ,n =18)。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的地位 ,其它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 。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+micronutrients supplement(Z+M),and micronutrients supplement(M),Before the supplements,hair Zn contemt of children was 2 28±0 74μmol/g and 22 22% of the hair Zn content was lower than 1 68μmol/g?There was a positive correlation between intelligence quotient(IQ) and hair Zn content .After suppl...
