闽南山区学龄前儿童5种微量元素检测结果分析

Analysis of the detection results of 5 trace elements in preschool children of the mountain area in the south of Fujian

目的通过对闽南山区405例学龄前儿童5种微量元素的检测,了解其微量元素水平,为建立合理的膳食结构提供依据。方法使用原子吸收光谱仪对405例学龄前儿童进行铜、锌、钙、镁、铁5种元素的检测,并用SPSS 19.0软件进行统计分析。结果 405例学龄前儿童微量元素检测,发现在1岁~3岁年龄段儿童中锌含量的平均值低于正常值水平,在1岁年龄段的儿童铁含量的平均值低于正常值水平;在不同学龄组段学龄前儿童微量元素的检测中,以锌、钙、铁缺乏差异有统计学意义（P〈0.05）。同时在不同学龄组段学龄前儿童中,以锌和铁微量元素缺乏最为明显,分别为65.93%和34.07%,并且随着年龄的增加,缺乏比例逐渐下降。结论学龄前儿童锌、铁缺乏较为严重,尤其以3岁以下的儿童为主。重视微量元素的监测和合理饮食的指导至关重要。

Objective Based on the detection of 5 trace elements in 405 preschool children of the mountain area in the south of Fujian,to investigate its trace elements levels,and provide basis for formulating a rational dietary composition. Methods Atomic absorption spectrometry was use to detect the cuprum,zinc,calcium,magnesium and iron in 405 preschool children,and then SPSS 19. 0 was used for the statistical analysis. Results In the detection of trace elements in the 405 preschoolers,the result showed that the average zinc content was less than normal among children of 1- 3 age group,and that the average iron content was less than normal in 1 year old children; there was statistic significance on the differences in deficiency rates of zinc,calcium,iron,among different preschool- age group（ P〈0. 05）. And in different preschool- ages groups,there was the most obvious lack of zinc and iron,which were 65. 93% and 34. 07%,and with age increased,the lack proportion decreased gradually. Conclusion Preschoolers zinc,iron deficiency was more serious,especially for children under the age of 3. It was essential to attach importance to the monitoring of trace elements and guide proper diet in reason.
