摘　　要：目的:检测学龄前儿童末稍血中钙、铁、锌、镁、铜元素的水平,为预防疾病提供科学依据。方法:采用MP-2型溶出分析法检测。结果:各种元素构成比正常;<2岁组、2～5岁组、>5岁组儿童钙、铁、锌、铜构成比比较差异无统计学意义(P>0.05);镁元素在3个年龄组儿童构成比比较差异有统计学意义,>5岁组与≤5岁组比较差异有统计学意义,镁元素缺乏率高。结论:营养素钙、铁、锌、铜在学龄前儿童体内的分布合理;镁元素的缺乏在学龄前儿童中占有一定的比例,机体可存在长期缺镁而无低镁血症现象,建议将营养素的检测纳入学龄前儿童保健常规检查项目。Objective ： To detect the levels of five trace elements in peripheral blood of preschool children, provide a scientific basis for preventing diseases. Methods： MP - 2 stripping analysis was used in the study. Results： The proportions of five trace elements were normal, there was no significant difference in the levels of calcium, iron, zinc and copper between different age groups （P 〉 0. 05 ） , but there was significant difference in the level of magnesium. The rate of magnesium deficiency was high. Conclusion： The distributions of calcium, iron, zinc and copper are reasonable in peripheral blood of preschool children; but a certain number of preschool children have low magnesium level, which may lead to a long - term magnesium deficiency yet no hypomagnesemia, therefore, the detection of nutrient elements should also be included in the normal heahheare check - up of preschool children.
