2014—2016年惠州地区573例老年人全血矿物质元素水平分析

Analysis of mineral elements in whole blood of 573 elderly people in Huizhou area during 2014—2016

目的 了解老年人全血的钙、镁、铁、锌、铜五项元素的含量和缺乏情况,分析元素缺乏的相关因素,为指导老年人合理膳食和适度补充矿物质提供依据.方法 用原子吸收光谱法测定2014年1月至2016年12月共573例老年人（年龄≥60）全血五项元素的含量,分析元素缺乏情况.结果 573例老年人全血中主要缺乏元素为钙、锌和铁,缺乏率分别为26.2%、20.6% 和19.4%,镁和铜元素缺乏率较低,分别是1.6% 和1%.男性比女性更易缺乏钙,女性比男性更易缺乏锌和铁.钙和镁、铁缺乏具有相关性,铁和钙、镁、锌缺乏具有相关性.结论 广东惠州地区老年人五项元素缺乏以钙、锌和铁为主,应重视改善元素缺乏情况,维持元素平衡,从而提高老年人生活质量.

Objective To investigate the levels and deficiency of five mineral elements of calcium （Ca）,magnesium （Mg）,ferrum （Fe）,zinc （Zn）and cuprum （Cu）in the elderly people and to analyze the relevant factors.To provide evidences of guidance for ra-tional dietary and proper minerals intake.Methods The levels of five mineral element in whole blood of 573 elderly people （age≥60）was monitored by atomic absorption spectrometry from January 2014 to December 2016.The deficiency of element was ana-lyzed.Results The major deficient whole blood elements were Ca,Zn and Fe in elderly people,and the deficiency rate was 26.2%, 20.6% and 19.4,respectively.The deficiency rate of Cu and Mg was lower,and it was 1.6% and 1%,respectively.The deficiency of Ca occurred easier in male than female.However,the deficiency of Zn and Fe were the contrary.The deficiency of Ca was correla-ted to Mg and Fe,and Fe was correlated to Ca and Mg.Conclusion The major deficiency elements of elderly people are Ca,Zn and Fe in Huizhou,Guangdong.Attention should be paid to improve the situation of element deficiency and to keep the balance of each element in order to improve their life equality.
