本文通过对3642名儿童发锌检测资料分析,认为发锌确能反映儿童群体的锌营养状况,但一些儿童个体发锌值并不完全与其锌营养状况一致。因此判断儿童个体锌营养状况时除参考发锌值外,还应结合锌摄入量、生长发育和各种缺锌表现等指标综合判定。本文认为发锌正常值下限仍以<110ppm为宜,提出110～70ppm为体内锌营养下降或可能轻度缺锌,<70ppm为缺锌。
In this paper, 3642 children made zinc test data analysis, that hair zinc does reflect the status of children’s zinc nutrition, but some children hair zinc value is not entirely consistent with its zinc nutrition status. Therefore, to determine the nutritional status of children in addition to zinc reference zinc hair, it should also be combined with zinc intake, growth and development and a variety of indicators of zinc deficiency comprehensive evaluation. In my opinion, the lower limit of the hair zinc normal is still <110ppm is appropriate, 110 ~ 70ppm is proposed for the body of zinc nutrition decreased or may be mild zinc deficiency, <70ppm zinc deficiency.
