目的:了解儿童体内钙、铁、锌、铜元素的含量,探讨其缺乏及超标的综合防治措施。方法:在儿童保健门诊随机抽样1000例儿童,分三个年龄组(婴儿、幼儿及学龄前儿童),使用原子吸收光谱仪,检测铁、锌、钙、铜含量。结果:儿童血微量元素失衡情况在三个年龄组中较常见,锌的缺乏在婴幼儿时期明显高于学龄前儿童,差异有显著性(P<0.05);铁的缺乏在婴儿期明显高于幼儿和学龄前期差异有显著性(P<0.05);钙的缺乏在学龄前期高于婴儿期差异有显著性(P<0.05)。各种元素缺乏在性别上无明显差异(P>0.05)。结论:儿童为生长发育较快时期,易缺乏铁、锌、钙元素,尤其是缺锌,易被忽视。应加大宣传及防治力度,强调饮食合理,营养平衡。
Objective: To understand the contents of calcium, iron, zinc and copper in children and to explore the comprehensive prevention and control measures of its deficiency and excess. Methods: A total of 1000 children were randomly divided into three age groups (infants, toddlers and preschool children) at child health clinics. The content of iron, zinc, calcium and copper were detected by atomic absorption spectrometer. Results: The imbalance of trace elements in blood of children was more common in three age groups. The deficiency of zinc in infants was significantly higher than that in preschool children (P <0.05). The deficiency of iron in infants was significantly higher than that in infants There was significant difference between preschool children and preschool children (P <0.05). The deficiency of calcium in preschool children was higher than that in infancy (P <0.05). The lack of various elements in gender was no significant difference (P> 0.05). Conclusion: Children are fast growth and development, easy to lack of iron, zinc, calcium, especially zinc deficiency, easily overlooked. Should increase publicity and prevention efforts, emphasizing a reasonable diet, nutritional balance.
