合肥市部分儿童外周血中铜、锌、钙、镁、铁和铅元素测定结果分析

Analysis on peripheral blood levels of iron,zinc,calcium,copper,magnesium and lead in children of certain region

目的了解合肥市部分1～6岁儿童外周血中铜、锌、钙、镁、铁和铅元素水平,探讨铜、锌、钙、镁、铁和铅元素缺乏的综合防治措施,为儿童合理补充这些元素提供参考。方法以在该院儿保门诊体检的4507例1～6岁儿童为研究对象,采用原子吸收光谱仪,测定其外周血中铁、锌、钙、铜、镁和铅的含量。结果结果表明,铜、锌、钙、镁、铁和铅元素的平均值均在正常值之内;通过进一步分析铜、锌、钙、镁和铁元素的缺乏率,得到锌元素的缺乏较为严重,从1周岁到6周岁的儿童,其锌元素的缺乏率分别为96.1%、83.2%、63.8%、49.8%、40.7%和38.6%。而其他铜、锌、钙、镁和铁元素的缺乏率较小。结论儿童在1～6岁生长发育最快,容易导致缺乏锌元素和铁元素,且年龄越小越易缺乏。该结果为父母给儿童正确营养搭配,合理膳食提供了很好的参考。

Objective To analyze the contents of iron , zinc , calcium , copper , magnesium and lead in peripheral blood of children at the age of 1-6years old and to explore comprehensive preventions and treatments for children lacking of these elements to pro- vide references for reasonable supply to children.Methods 4 507outpatients samples in this hospital were taken from children at the age of 1-6years old in 2010-2011.The contents of iron , zinc , calcium , copper , magnesium and lead in peripheral blood were measured by atomic absorption spectrometry.Results The average contents of iron , zinc , calcium , copper , magnesium and lead in peripheral blood were at normal range.By further analysis of the rate of micronutrient deficiencies , serious lack of zinc could be demonstrated.The rate of zinc deficiencies was 96.1% , 83.2% , 63.8% , 49.8% , 40.7% and 38.6%in children at the age of 1-6 years old , respectively.The deficiencies of the other elements were very low.Conclusion The children （ 1-6years old ） might be at the fastest periods of growth and development , causing deficiency of zinc and iron.Results of this research could provide guidelines or advice that child health care should take proper nutrition and reasonable diet.
