不同年龄成年男性血清微量元素含量比较

目的 了解中国6个省市不同年龄的男性血清锌、铜、锰、铅、镉含量的差别及变化。方法 2001年12月～2002年12月，在石家庄、郑州、太原、贵阳、杭州和青岛6个地区的市区和郊县选择在当地居住10年及以上的男性为研究对象。进行结构式问卷调查和血清微量元索的原子吸收分光光度法检测。采用 单因素和多因素相结合的方法分析年龄对血清微量元素含量的影响。结果 6个地区调查对象的血清锌、铜、锰、铅、镉含量有所不同；年龄对血清微量元素也有一定的影响，随着年龄组的增加血清铜、锰、铅、镉含量均增加。结论 人体内血清微量元素含量存在着地区差异；中国6个地区20～59周岁之间成年男性的血清铜、锰、铅、镉含量随年龄组增加而增加。

Compare of serum trace elements in different age groups of male adults

Objective To understand the difference and variety of serum zinc,copper,manganese,lead and cadmium among different age groups of male adults in six cities,in China.Methods Men,who lived in Shijiazhuang,Zhengzhou,Taiyuan,Guiyang,Hangzhou and Qingdao more than 10 years,were recruited from Dec 2001 to Dec 2002.Questionnaire survey and serum microelement's test were both conducted.Univariate and mutil-variable analyses were combined to explore the influence of age on serum trace elements.Results There were some differences of trace elements between Shijiazhuang,Zhengzhou,Taiyuan,Guiyang,Hangzhou and Qingdao.Moreover,age may has some influence on serum trace elements,and the contents of serum copper,manganese,lead and cadmium raised by aging.Conclusion Serum trace elements had regional differences,and the level of serum copper,manganese,lead and cadmium increased with the age group's added among male adults of 20 to 59 years old in six cities,in China.
