目的了解青岛市市北区0～6岁儿童铜、锌、钙、镁、铁5种微量元素水平。方法应用BH5100原子吸收法光谱仪对儿保门诊的1271名0～6岁儿童末梢血中铜、锌、钙、镁、铁元素测定。结果1271例0～6岁儿童微量元素缺乏情况为:低血锌者373例,缺乏率为29.35%;低血铁者270例,缺乏率为21.24%;低血钙者250例,缺乏率为19.67%;低血铜者11例,缺乏率为0.87%。微量元素超标情况为:血铜和血铁无超标者;高血钙者24例,超标率为1.89%;高血锌者3例,超标率为0.24%;高血镁者1例,超标率为0.08%。结论目前社会上重视补钙的意识强于铜、锌、铁元素的补充,高血钙的发生率居首位。因此要加大儿童科学喂养的宣传力度,做好平衡膳食、科学进补的指导,维持儿童体内微量元素含量的正常与均衡,以保证儿童健康成长。
Objective To understand the levels of five trace elements Cu, Zn, Ca, Mg and Fe in children aged 0 ~ 6 in Shibei District of Qingdao City. Methods The concentrations of copper, zinc, calcium, magnesium and iron in peripheral blood of 1271 children aged 0 ~ 6 years were measured by BH5100 atomic absorption spectrometry. Results There were 373 cases of low blood zinc and 29.35% of children with hypokalemia in 270 cases of children aged 0-6 years. 270 cases of hypokalemia, the lack of rate was 21.24%, 250 cases of hypocalcemia, the lack of rate was 19.67%; low blood copper in 11 cases, the lack rate of 0.87%. Trace elements exceeded the situation: no blood copper and blood iron exceeding the standard; 24 cases of hypercalcemia, exceeding the rate of 1.89%; high blood zinc in 3 cases, exceeding the standard rate of 0.24%; 1 hyperglycemia, excessive rate 0.08%. Conclusion At present, the awareness of calcium supplementation in society is stronger than that of supplementation of copper, zinc and iron, with the highest incidence of hypercalcemia. Therefore, it is necessary to increase the propaganda of children’s scientific feeding and do a good job of balancing diet and scientific tonic guidance so as to maintain the normal and balanced content of trace elements in children so as to ensure the healthy growth of children.
