目的:了解婴幼儿体内无机元素的含量状况,有针对性的指导家长合理的给幼儿补充无机元素。方法:选取0~3岁421例健康检查婴幼儿,抽取指血100μl,用BH-5100型火焰原子吸收光谱仪等仪器及配套试剂检测血中无机元素的含量并对结果进行分析。结果:婴幼儿指血铁、铜、锌、锰、钙、镁的平均含量分别为432.86μg/m l、0.80μg/m l、6.02μg/m l、0.07μg/m l、67.24μg/m l、37.40μg/m l;锌、钙、铜元素不足者分别占29.40%、7.60%、7.40%,锌、铁元素过量者分别占5.70%、4.00%;铜元素不足除13.92%2~岁和12.20%3~岁组儿童明显高于0~岁和1~年岁龄组(分别为5.17%和4.72%)外(P<0.05),其他元素的平均含量以及不足和过量的百分人数在不同性别、不同年龄婴幼儿之间差别无统计学意义(P>0.05)。结论:部分婴幼儿存在锌、钙、铜、铁元素不足或过量的情况,其中以锌的异常人数比例最高;应注意调整婴幼儿的饮食结构,确保维持各种营养素的平衡,合理补充不足的无机元素。
Objective: To understand the content of inorganic elements in infants and young children, targeted parents to guide children reasonable to supplement inorganic elements. Methods: A total of 421 healthy infants and children aged 0 ~ 3 years were enrolled in this study. 100μl blood was drawn from the finger. The content of inorganic elements in the blood was detected by BH-5100 flame atomic absorption spectrometer and the related reagents. The results were analyzed. Results: The average levels of blood iron, copper, zinc, manganese, calcium and magnesium in infants and young children were 432.86μg / ml, 0.80μg / ml, 6.02μg / ml, 0.07μg / ml, 67.24μg / ml and 37.40μg / ml; zinc, calcium and copper deficient accounted for 29.40%, 7.60%, 7.40%, respectively, while zinc and iron overdose accounted for 5.70% and 4.00% respectively; copper deficiency was 13.92% 2 to 12.20% Group children were significantly higher than those of 0 ~ year old and 1 ~ age group (5.17% and 4.72% respectively) (P <0.05). The average content of other elements, as well as the percentage of deficient and excessive percentage were significantly higher in different gender, No significant difference between infants and young children (P> 0.05). Conclusions: Some infants and young children have the deficiency or excessive amount of zinc, calcium, copper and iron, among which the proportion of abnormal zinc is the highest. It is necessary to adjust the diet of infants and young children to ensure the balance of various nutrients, Inorganic elements.
