摘要
对１４０名３～６岁缺锌儿童的营养调查表明：除维生素Ａ和铁外，其它多种营养素摄入偏低，锌与优质蛋白质摄入不足。临床体格检查与实验室检查发现，这些儿童血浆锌含量低下（６５８．２±７９．３ｍｇ／Ｌ），有食欲不振、厌食等表现。血清白蛋白水平正常，没有脱发、皮肤损害等体症，经补锌治疗后血浆锌显著升高，提示这些儿童为边缘性锌缺乏。
The results of dietary survey of 140 zinc deficient children aged 3￣6 showed that except VA and Fe, the intake of all the other nutrients were lower and intake of zinc and high-quality protein was insufficient. Clinical and laboratory examination revealed that these children had only reduced plasma zinc and light symptoms of zinc deficient such as poor appetite, but the level of serum ALB was normal, and without the sighs of hair loss and skin lesions. After zinc administration, plasma zinc level was significantly inhanced. It seems that these children were suffering from marginal zinc deficiency.
