目的:了解本地区0～14岁健康儿童微量元素情况,为临床用药及儿童饮食调节提供可靠依据。方法:采用BH5100型原子吸收光谱仪,对1825例儿童血液中所含Cu、Zn、Fe、Ca、Mg、Pb6种必需微量元素进行检测,数据采用统计软件SPSS10.0处理。结果:此六种微量元素含量在男童、女童间无差异;比较不同年龄组儿童全血微量元素,镁和铅含量无差异。钙、铁、锌、铜含量有显著差异。结论:随年龄增长,缺锌及缺铁儿童比例呈下降趋势,而缺钙、铅中毒儿童比例呈增加趋势,儿童体内微量元素含量与其生长发育状态、饮食结构调整及环境有关。
Objective: To understand the situation of trace elements in healthy children aged 0 ~ 14 years in this area and provide a reliable basis for clinical medication and children’s diet regulation. Methods: The trace elements of Cu, Zn, Fe, Ca, Mg and Pb contained in blood of 1825 children were detected by BH5100 atomic absorption spectrometer. The data were processed by SPSS 10.0 software. Results: There was no difference in the content of these six trace elements between boys and girls. There was no difference in the content of magnesium and lead between children in different age groups. Calcium, iron, zinc, copper content were significantly different. CONCLUSION: With the increase of age, the proportion of children with zinc deficiency and iron deficiency shows a decreasing trend. However, the proportion of children with calcium deficiency and lead poisoning shows an increasing trend. The content of trace elements in children is related to their growth and development, diet structure adjustment and environment.
