目的了解儿童微量元素缺乏情况并指导临床给予合理补充。方法利用火焰原子吸收分光光度法检测儿童末梢血Zn、Fe、Ca、Cu、Mg的含量;利用原子荧光光度法检测铅。结果 Zn、Fe、Ca 3种微量元素缺乏比较普遍,婴幼儿组缺铁和缺锌的比例较高,学龄组缺钙的比例最高,铅中毒的发生率较低。结论一些儿童体内微量元素紊乱,及时合理地添加辅食、平衡膳食是儿童生长发育的重要因素;检测儿童微量元素含量对及时合理地补充微量元素有重要的意义。
Objective To understand the lack of trace elements in children and to guide the clinical rational supplementation. Methods The contents of Zn, Fe, Ca, Cu and Mg in peripheral blood of children were detected by flame atomic absorption spectrophotometry. Lead was detected by atomic fluorescence spectrometry. Results The lack of trace elements such as Zn, Fe and Ca was common. The proportion of iron deficient and zinc deficiency in infants and young children was higher than that in infants and young children. The highest rate of calcium deficiency was found in school-age group and the incidence of lead poisoning was lower. Conclusions Some children have disorders of the trace elements in the body and timely and reasonably add supplementary food. The balanced diet is an important factor for children’s growth and development. Detecting the content of trace elements in children is of great significance to the timely and reasonable supplement of trace elements.
