乌鲁木齐市523例儿童全血微量元素检测结果分析

Analysis on detection results of trace elements in the whole blood samples of 523 children in Urumchi city

目的:了解婴幼儿及学龄儿童体内铁、锌、钙等元素的含量,探寻微量元素失衡的综合防治措施。方法:在儿童保健门诊随机抽取523例儿童,分为婴儿组、幼儿组、学龄前组及学龄期组,采用原子吸收光谱法检测全血铁、锌、钙、镁、铜、铅含量。结果:523例儿童中,缺锌69%(361/523),缺铁43.4%(227/523),铜、镁、铅无明显失衡。少数民族儿童铅和锌的含量高于汉族儿童,钙和铁的含量低于汉族儿童。男童钙含量低于女童,铅含量高于女童。不同年龄组儿童全血铁、锌、钙、镁、铜、铅含量差异均有统计学意义,且各年龄组儿童铅含量有随年龄升高的趋势。结论:婴幼儿期为生长发育最快时期,易缺乏锌、铁等元素,应均衡饮食,合理补充微量元素,以保证婴幼儿健康成长。

Objective：To understand the contents of trace elements,such as iron,zinc and calcium,in infants and preschool children,explore comprehensive preventive measures.Methods：523 children were selected from children health care outpatient randomly,then they were divided into infant group,child group,preschool child group and school child group,atomic absorption spectrometry was used to detect the contents of iron,zinc,calcium,magnesium,copper and lead in whole blood samples.Results：Among 523 children,the incidences of zinc deficiency and iron deficiency were 69%（361/523） and 43.4%（227/523）,respectively,copper,magnesium and lead were not deficient obviously.The contents of lead and zinc in ethnics minority children were higher than those in Han nationality children,the contents of calcium and iron in ethnics minority children were lower than those in Han nationality children.The content of calcium in boys was lower than that in girls,while the content of lead in boys was higher than that in girls.There was significant difference in the contents of iron,zinc,calcium,magnesium,copper and lead in whole blood samples among different age groups,and the contents of lead in different age groups showed increasing trends with age.Conclusion：The growth and development of children during infantile period are the fastest,zinc deficiency and iron deficiency are prone to occur,balanced diet and reasonable supplement of trace elements may ensure the healthy growth of infants.
