目的:观察儿童体内血铜、铁、锌、钙、镁的水平,分析当前武威市儿童微量元素缺乏症的特点,为儿童合理补充微量元素,调整饮食结构及健康指导提供理论依据。了解微量元素含量的变化与其临床意义。方法:采用原子吸收对2012年1月~2013年10月对来武威市妇幼保健院体检的416例儿童的末梢血进行微量元素铜、铁、锌、钙、镁检测,把这些儿童分成6个月~2岁、2~4岁、4~6岁3个年龄组,分析微量元素水平变化因素与疾病的关系。结果:6个月-2岁儿童缺锌和缺铁的发生率高于4~6岁儿童,缺钙发生率低于4~6岁儿童。结论:儿童微量元素缺乏需饮食结构调整和给予合理的药物补充。微量元素缺乏与厌食、贫血、皮肤粗糙、头发稀少等临床疾病和和症状有一定关系,在临床诊断与治疗中予以重视。微量元素含量测定有助于了解儿童的营养状况,指导其儿童保健。
OBJECTIVE: To observe the levels of blood copper, iron, zinc, calcium and magnesium in children, analyze the characteristics of children’s microelement deficiency in Wuwei city, and provide theoretical basis for children to rationally supplement trace elements and adjust diet structure and health guidance. Understand the changes of trace elements content and its clinical significance. Methods: The trace amounts of copper, iron, zinc, calcium and magnesium in peripheral blood of 416 children who were taken to Wuwei MCH from January 2012 to October 2013 were measured by atomic absorption. The children were divided into 6 Month to 2 years old, 2 to 4 years old, 4 to 6 years old three age groups, analysis of the relationship between the level of trace elements and disease. Results: The incidence of zinc deficiency and iron deficiency in children aged 6 months to 2 years was higher than that of children aged 4 to 6 years. The incidence of calcium deficiency was lower than that of children aged 4 to 6 years. Conclusion: The lack of trace elements in children needs adjustment of dietary structure and reasonable drug supplementation. Lack of trace elements and anorexia, anemia, rough skin, hair loss and other clinical diseases and symptoms have a certain relationship, in clinical diagnosis and treatment of attention. Determination of trace elements helps to understand children’s nutritional status, to guide their child care.
