东莞地区2050名小儿6种微量元素结果的分析

Analysis of six kinds of serum microelements from 2050 chidren in Dongguan area

目的了解本地小儿体内钙、铁、锌、铜、镁、铅等微量元素水平,为更好地指导儿童合理补充微量元素提供科学依据。方法使用原子吸收法检测微量元素,对本地三个年龄段小儿2050名血清钙、铁、锌、铜、镁检测结果和1154名全血铅检测结果做回顾性分析。结果 6种微量元素含量在不同性别之间差异均无统计学意义(P>0.05);各年龄组血清铁缺乏率最高,总缺乏率为21.56%,其次是锌缺乏率,占13.41%,同时缺锌、铁率为5.37%;各年龄组中以铜中毒率最高,总中毒率为6.10%,其次是铅中毒率,占1.47%。结论小儿阶段是生长发育较快时期,易出现微量元素失衡。需对各年龄段小儿定期进行微量元素分析,保证儿童健康成长。

Objective To offer a scientific proof for better guiding the children to add microelements.Methods Six kinds of microelements,including Calcium,Zinc,Ferrum,Cuprum,Magnesium and Lead,were detected by atomic absorption method.Results In the testing results from 2050 serum samples and 1154 full-blood samples,there was no statistic difference between two genders in concentrations of 6 microelements（P￡？0.05）.The deficiency rate（21.56%） of serum iron was the highest in all age groups,and the secondary was the deficiency rate of Zinc（13.41%）.The deficiency rate both Zinc and Ferrum was 5.37%.Cuprum poisoning rate（6.10%） was the highest in all age groups,and next was the Lead poisoning rate（1.47%）.Conclusions The children with stage of rapid growth and development are prone to imbalance in trace elements.Microelements need to be detected regularly to ensure healthy growth of children.
