目的:了解辽阳市2007年0～7岁儿童铜、锌、钙、镁、铁5种微量元素水平。方法:应用BH5100原子吸收光谱仪对儿保门诊的1163名0～7岁儿童血中铜、锌、钙、镁、铁元素测定。结果:1163名0～7岁儿童微量元素缺乏情况为:低血锌者540例,缺乏率为46.43%;低血铁者239例,缺乏率为20.55%;低血铜者138例,缺乏率为11.87%;低血钙者75例,缺乏率为6.45%;低血镁者1例,缺乏率为0.09%。微量元素超标情况为:血铜和铁无超标者;高血镁者1例,超标率为0.09%;高血锌者9例,超标率为0.77%;高血钙者55例,超标率为4.73%。结论:目前社会上重视补钙的意识强于铜、锌、铁元素的补充,使血钙的缺乏明显低于血铜、锌、铁元素的缺乏,而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,以保证儿童健康的成长。
Objective: To understand the levels of five trace elements Cu, Zn, Ca, Mg and Fe in children aged 0-7 years in Liaoyang in 2007. Methods: The contents of Cu, Zn, Ca, Mg and Fe in 1163 children aged 0 ~ 7 years old undergoing childbirth clinic were determined by BH5100 atomic absorption spectrometry. Results: The lack of trace elements in 1163 children aged 0-7 years: 540 cases of low blood zinc, the lack rate of 46.43%; 239 cases of low blood iron, the lack of rate was 20.55%; 138 cases of low blood lead, the lack of rate For 11.87%; 75 cases of hypocalcaemia, the lack of rate was 6.45%; 1 case of low blood magnesium, the lack of rate of 0.09%. Excessive levels of trace elements: blood copper and iron are not exceeded; hypermagnesemia in 1 case, exceeding the rate of 0.09%; high blood zinc in 9 cases, exceeding the standard rate of 0.77%; 55 cases of hypercalcemia, exceeding the standard rate 4.73%. Conclusion: At present, the awareness of calcium supplementation in the community is stronger than that of copper, zinc and iron supplementation. The lack of serum calcium is obviously lower than the lack of blood copper, zinc and iron, while the incidence of hypercalcemia is the highest. 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 children’s microelements so as to ensure the healthy growth of children.
