宝鸡地区630例儿童全血元素检测结果分析

Analysis of mineral elements in whole blood of 630 children in Baoji

目的了解宝鸡地区儿童体内5种元素（铜、锌、钙、镁、铁）含量的现状,为制定预防措施提供依据。方法选择630名健康体检的儿童（4月~14岁）,按年龄分成婴儿、幼儿、学龄前、学龄期4组,采集静脉血,使用BH5100型多通道原子吸收光谱仪检测全血中铜、锌、钙、镁、铁的含量,并对数据进行t检验和方差分析。结果 630例儿童不同性别全血5种元素（铜,锌,钙,镁,铁）水平间差异无统计学意义（P〉0.05）,不同年龄组铜、锌、钙、铁水平比较差异有统计学意义（P〈0.05）;而不同年龄组镁水平比较差异无统计学意义（P〉0.05）。630例儿童中缺锌268例（42.5%）、缺铜126例（20.0%）、缺铁114例（18.1%）、缺钙84例（13.3%）、缺镁6例（1%）。结论儿童处于生长发育期,易缺乏铁、锌、铜等元素,尤其是缺锌,易被家长忽视。应加大宣传及防治力度,强调饮食合理,营养平衡。

Objective To understand the present situation of five elements（ copper,zinc,calcium,magnesium,iron） in children in Baoji area,and provide basis for developing corresponding preventive measures. Methods A total of 630 healthy children between 4 months and 14 years old were divided into infants group,young children group,preschool children group and school-age children group. Venous blood was collected from these children to detect the contents of copper,zinc,calcium, magnesium and iron by BH5100 type multichannel atomic absorption spectrometer. The detection results were analyzed by t est and variance. Results The contents of the five elements（ copper,zinc,calcium,magnesium,iron） in whole blood had no significant statistical difference between boys and girls（ P〉 0.05）,while the content difference of cooper,calcium,zinc and iron had statistical significance among different age groups（ P〉 0.05）. Magnesium level had no statistical difference among different age groups（ P〉 0.05）. In the 630 children,zinc deficiency was found in 268 cases（ 42. 5%）,copper deficiency was found in 126 cases（ 20. 0%）,iron deficiency was found in 114 cases（ 18. 1%）,calcium deficiency was found in 84 cases（ 13. 3%）,and magnesium deficiency was found in 63 cases（ 1%）. Conclusion Children are still growing,susceptible to lack iron,zinc,copper and other elements,especially zinc deficiency is easily ignored by parents. So the reasonable diet and balanced nutrition is necessary for children in daily life.
