摘要
为了解沈阳市0～7岁儿童全血铜、锌、钙、镁、铁元素缺乏情况,探讨性别、年龄与5种元素含量之间的关系,对沈阳市20 335名0～7岁儿童进行末梢指间采血,用BH 5100型原子吸收光谱仪测定了全血中钙、镁、铜、铁、锌的含量。结果表明,儿童血锌平均水平低于正常值范围,缺乏最严重,缺乏率为77.78%;血铜、锌、铁缺乏率与年龄有线性相关关系,且随着年龄的增加呈现下降趋势(P<0.05),下降速度在40%～60%之间;全血中5种元素均存在年龄差异(P<0.01),血铜元素男童明显高于女童(P<0.01)。提示儿童应加强膳食干预,提高各种富含微量元素的食物摄入,以促进儿童的生长发育。
To understand the Shenyang 0 -7 years old children＇s whole blood copper, zinc, calcium, magnesium, iron lack of conditions, discusses the relationship between the gender, age and five elements, between peripheral in Shenyang 20 335 0 -7 years old children refers to the collection, the content of five elements, calcium, magnesium, copper, iron, and zinc was determined by BH type 5100 atomic absorption spectrometer. The results show that the average blood zinc children less than normal range, lack the most serious, lack of rate is 77.78% ; blood Cu, Zn, Fe lack of rate and age have a linear correlation, and with the increase of age has declined （ P 〈 0. 05 ） and the decreasing speed between 40% ~ 60% ; The five elements in whole blood there are age difference （ P 〈 0. 01 ） , blood was significantly higher than the girl boy copper elements （ P 〈 0.01 ）. It concludes children should strengthen the dietary intervention, improve all kinds of trace elements in the food intake, to promote children＇s growth.
