摘要: 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(P0.05);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。Abstract: 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 status． 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 A1l contents of the five trace elements were among the normal reference values and were in the balante．By compar-ing the gender，it was found that the Fe content of the girls was a little bit lower than that of the boys ((PPP>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 in-fluence of the trace elements on the development of the child'S body and mind should not be underes-timated．Balanced foods are needed in order to maintain the balalice of the trace elements．
