幼儿头发中微量元素含量与身高、体重关系研究

普查了４４９名１－６岁儿童头发中锌、铁、铜、钙、锰、铅含量，用分层聚类分析法对其身高、体重与各元素进行相关分析。幼儿身高与头发中锌含量呈相关关系，与头发中铅含量呈负相关关系。体重与头发中锌含量呈显著的正相关关系。与头发中铅含量呈负相关关系。说明锌有利于身体发育，而铅对身体发育不利。

The Studies on Relations between Trace Elements in Hair and Body Height and Weight

The content of6 kinds of inorganic elements(Zn, Fe , Cu, Ca, Mn and Pb)in hair of 4449 teenagers,1 to 7years old, was stu died by hierarchical cluster method. The results show that(1)The content of Zn in hair of children is positive relation(its correlation coefficient i s0.144)with body height of children,and the content of Pb in hair of children is negativerelation(its correlation coefficient is -0. 186)with body height of children.(2) Thecontent of Zn in ha ir o f children is positive relation(its correlation coefficient is0.113)wi th body weight of children,and the content of Pb in hair of children is negativerelation(its correlation coefficient is -0.114) with body weight of c h ildren. Thecontent of Zn in body of children is beneficial to growth of body,an d the high content ofPb in body of children is unfavourable to growth of body.
