目的：了解成都地区0～6岁儿童微量元素的含量及在不同年龄段的变化情况。方法采用B H5100 T型原子吸收光谱仪对四川省人民医院2015年4～11月786例0～6岁体检儿童微量元素Cu、Zn、Ca、Mg、Fe进行检测，对检测结果进行统计学分析。结果成都地区体检儿童微量元素Cu、Zn、Ca、M g、Fe的缺乏率分别为0．4％、5．0％、18．1％、9．5％、8．3％，其中＜1岁、1岁、2岁、3岁和≥4岁儿童Ca的缺乏率分别为47．4％、27．5％、12．6％、9．9％、11．9％，可见＜1岁儿童Ca的缺乏率较高。各年龄组中Ca的缺乏率比较差异有统计学意义（P＜0．05），各年龄组男女儿童几种微量元素的缺乏率均无性别差异。结论成都地区0～6岁体检儿童微量元素异常率较高，其中Ca的缺乏率最高，同时M g和Fe也较为缺乏。儿童微量元素含量与喂养习惯有密切关系，该地区的0～6岁儿童应注意微量元素的补充，尤其是Ca的补充，同时提倡母乳喂养。%Objective To know the contents and changes situation of trace elements among children aged 0-6 years old in Chengdu are‐a .Methods The BH5100T atomic absorption spectrometry was adopted to detect the levels of trace elements Cu ,Zn ,Ca ,Mg ,Fe in 786 children aged 0-6 years old undergoing the physical examination in our hospital from April 2015 to November 2015 .The detection results were statistically analyzed .Results The deficiency rates of Cu ,Zn ,Ca ,Mg and Fe in Chengdu area were 0 .4% ,5 .0% ,18 .1% ,9 .5% and 8 .3% respectively ,in which the deficiency rates of Ca in children aged <1 ,1 ,2 ,3 ,≥ 4 years old were 47 .4% ,27 .5% ,12 .6% ,9 .9% and 11 .9% respectively ,indicating that the Ca deficiency rate in children < 1 years old was higher .The Ca deficiency rate had statistical differ‐ence among different age groups(P<0 .05) ,and there were no statistically significant differences in the deficiency rates of several trace ele‐ments among different age groups of male and female children .Conclusion The abnormality rate of trace elements among children aged 0-6 years old in Chengdu area is higher ,in which the Ca deficiency rate is highest ,meanwhile the Mg and Fe were lack too .The trace element content in children is closely related with the feeding habit .The 0-6 years old children in this area should pay attention to the supplement of trace elements ,especially supplement of Ca ,meanw hile breastfeeding is advocated .
