低碘地区小儿微量元素调查分析

目的为了解我市0～6岁儿童微量元素缺乏特点,指导临床选择最佳时段给儿童合理补充微量元素。方法随机抽查儿科门诊和母婴中心体检的0～6岁儿童548例进行微量元素检测并做统计学分析。结果我市儿童存在不同程度的微量元素缺乏情况,其中锌、铁、钙缺乏情况最为严重,发生率分别为27.37%,24.08%和15.09%,相对于镁、铜差异有统计学意义;而婴儿期缺铁最为明显,幼儿期缺锌最为明显,学龄前期缺钙最为明显;各种微量元素缺乏在性别上差异无显著性(P>0.05)。结论锌、铁、钙营养不足是我市儿童最主要的健康问题,微量元素摄入情况不容乐观,选择最佳时段补充微量元素,可以有效防止儿童微量元素的缺乏,避免滥用滥补微量元素的盲目性。

Objective In order to learn about the feature of children being short of microelements in our city and direct the clinical to choose the best period for supplementary microelements reasonably for children. Method Carry out random spot check on children at the age of o to 6 among 548 tested in paediatrics and the center of mother and infant. Results children are short of microelements in different degree. Among them , the most serious problem is lacking in Zn , Fe and Ca. The percentage is 27. 34%, 24.08%, 15.09% . Campared with the percentage of Mg and Cu. They are stricking. Lack of Fe is most apparent during baby period. Lack of Zn is most apparent during infant period. Lack of Ca is most apparent during preschool period. Lack of varities of microelements is not apparent in sex （ P 〉 0.05 ）. Conclusion Lack of Ca , Fe and Zn is the main healthy problem for children in our city. The situation for adding morn micoelements is not bright for us. Choosing best period can prevent the lack of microelements.
