2011年丽水市儿童全血5种微量元素检测结果分析

Analysis of five microelements in whole blood of children in Lihshui in 2011

目的:了解丽水市儿童体内铜、锌、钙、镁、铁5种微量元素水平,为更好地指导本地区儿童合理补充微量元素提供科学依据。方法:使用火焰原子吸收法检测5种微量元素,对本地3个年龄段1428名儿童全血铜、锌、钙、镁、铁检测结果做回顾性分析。结果:5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);5种微量元素中,锌总缺乏率最高,达到19.05%,且3个年龄段锌元素缺乏率差异有显著统计学意义(P<0.05),其次是铁缺乏,达到16.80%,钙总缺乏率较低,为3.64%。结论:丽水市儿童易出现锌、铁微量元素失衡,尤其0周～3周岁婴幼儿锌元素缺乏率高,应对儿童定期检测微量元素,及时采取措施,预防微量元素缺乏。

Objective：To provide a scientific proof for guiding people to better supply children microelement through investigating the microelement level（cuprum,zinc,calcium,magnesium,ferrum） in whole-blood of children in Lishui.Methods： Whole-blood levels of Cuprum,Zinc,Calcium,Magnesium,Ferrum in 1428 local children were detected by atomic absorption method and analyzed retrospectively.Results： There was no statistic difference in concentrations of 5 microelements between two genders[P0.05].The whole-blood Zinc deficiency rate was highest in 5 microelements,the total deficiency rate was 19.05%.There were statistic differences in the Zinc deficiency rates of three age groups.The second was the deficiency rate of Ferrum,accounting for 16.80%.The deficiency rate of Calcium was much lower,accounting for 3.64%.Conclusion： Children in Lishui were easy to be deficiency in Zinc and Ferrum,particularly the Zinc deficiency rate of 0-3 years old children was much high.Analyzing microelements on regular and taking timely measures may prevent microelements deficiency.
