临汾铁路地区少儿发中微量元素与营养状况关系分析

Analysis of the Relationship Between Trace Elements in Children's Hair and the Nutritional Status in the Railway District of Linfen

目的了解临汾铁路地区少儿发中各种微量元素含量,探讨与营养状况之间的关系。方法采用原子吸收法测定325名少儿发中铁、锌、铜、铅、硒5种元素含量,同时对营养状况进行评价。结果各种微量元素含量在正常参考值范围内,处于平衡状态。不同性别比较,Fe含量女生略低于男生(P<0.05):不同年龄比较,Fe、Cu、Pb含量在不同年龄组间略有差异(P<0.05)。5中微量元素含量在营养不组与正常组之间无明显差异(P>0.05);Fe、Cu的含量营养正常组低于超重、肥胖组(P<0.05)。结论微量元素对少儿身心发育的影响不可低估,应保证平衡膳食,防止微量元素的失衡。

Objective This study was to find out the contents of the trace elements in children＇s hair in the Railway District of Linfen, and to discuss the relationship with children＇s nutritional sums. Methods The contents of the five elements, Fe, Zn, Cu, Pb, and Se, in 325 children were identified by the Atomic Absorption. Meanwhile, their nutritional status were evaluated. Results All contents of the five trace elements were among the normal reference values and were in the balance. By comparing the gender, it was found that the Fe content of the girls was a little bit lower than that of the boys （P〈0.05）. When the age was compared, the contents of Fe, Cu, Pb were slightly varied with the age groups （P〈0.05）. In addition, the contents difference of the five trace elements between nutritional group and normal group was not significant （P〉0.05）, while the contents of Fe and Cu in the normal group were lower than those of overweight group and adiposity group （P〈0.05）. Conclusion The influence of the trace elements on the development of the child＇s body and mind should not be underestimated. Balanced foods are needed in order to maintain the balance of the trace elements.
