成都市2963例体检儿童微量元素检测结果分析

Analysis on detection results of trace elements in 2 963 children receiving physical examination in Chengdu city

目的:了解成都地区0～14岁儿童体内微量元素的含量,分析其异常的原因,探讨干预措施及纠正方法。方法:原子吸收光谱法检测2 963例正常儿童全血微量元素(铜、锌、钙、镁、铁、铅、镉)含量,比较年龄、性别对微量元素异常的影响。结果:成都地区正常体检儿童血锌、钙、铁和铅的异常率相对较高,血铅有随年龄增加异常率增加的趋势,血铁及血钙5岁以下组与5岁以上组异常率比较差异有统计学意义(P<0.05),各微量元素测定结果无性别差异。结论:儿童微量元素含量与生理周期及喂养习惯有密切关系,婴儿期应注意补铁,幼儿期侧重补钙,良好的生活环境及个人卫生习惯可以预防铅中毒的发生。

Objective： To understand the contents of trace elements in 0 - 14 years old children in Chengdu city, analyze the causes of abnormal trace elements contents, and explore the interventional measures and correction methods. Methods： Atomic absorption spectrometry was used to detect the contents of copper, zinc, calcium, magnesium, iron, lead, and cadmium in whole blood of 2 963 normal children, the effects of age and gender on abnormal trace elements. Results ： The abnormal rates of blood zinc, calcium, iron, and lead in children receiving physical examination in Chengdu city were relatively high, the abnormal rate of blood Dead showed an increasing trend with age, there were statistically significant differences in abnormal rates of blood iron and calcium between under 5 years old group and more than 5 years old group （P 〈 0. 05 ）, there was no gender difference in detection results of trace elements. Conclusion： The contents of trace elements in children are correlated with physiological cycle and feeding habits. Iron supplementation during infant period should be paid more attention, and calcium supplementation should be focused on during toddle period. Good living environmentand personal health habits can prevent lead poisoning.
