摘　　要：目的分析合肥市一年级小学生头发中Zn、Ca、Fe、Mg、Cu、Pb等6种矿物元素的含量并探讨矿物元素含量与食物摄入频率的关系。方法采用分层整群抽样的方法,抽取合肥市小学一年级在校学生进行采样,并对其家长进行问卷调查,获得有效样本180例。采用原子吸收分光光度法测定头发中矿物元素含量,并利用SPSS13.0统计软件进行数据处理。结果儿童体内矿物元素Fe、Zn、Cu、Ca、Mg存在一定程度的缺乏或过量,以缺乏较明显;儿童体内Pb含量升高也较明显。鸡蛋摄入频率、水产品摄入频率、碳酸饮料摄入频率及是否摄入保健品与各矿物元素的等级无关联;豆制品摄入频率与头发中的Fe、Zn、Cu、Mg和Ca的含量都有关联,不同等级间差异有统计学意义;不同水果摄入频率学生头发中的Fe、Zn和Mg的等级差异有统计学意义;坚果摄入频率与头发中的Fe、Zn、Mg和Ca的含量都有关联,不同等级间差异有统计学意义;西式快餐摄入频率与Pb的含量有关联,摄入频率越高,Pb过量几率越大。结论合肥市一年级小学生体内6种矿物元素含量均存在较明显的异常,矿物元素的含量与饮食结构具有相关性。Objective To determine six kinds of mineral elements（Zn,Ca,Fe,Mg,Cu,Pb） in hair of grade 1 primary school students in Hefei City and to analyze the relationship of mineral elements content with the intake frequency of diet.Methods Stratified cluster sampling of first-year students was performed in Hefei City and a self-designed questionnaire was used to investigate their parents.Then 180 effective samples were collected.Six kinds of mineral elements content in hair were determined by atomic absorption spectrometry.Then the result was analyzed by using SPSS 13.0 software.Results There was a certain degree of lack and excess of the six kinds of mineral elements in children,the lack was obvious.The lead levels of children were more apparent.The intake frequency of egg,seafood,carbonated drink and health food were not associated with six kinds of mineral elements content.The intake frequency of bean products was associated with Fe,Zn,Cu,Mg and Ca content in hair of children.The frequency of fruit intake was associated with Fe,Zn,and Mg content.The intake frequency of nut was associated with Fe,Zn,Mg and Ca content.The intake frequency of western fast food was associated with Pb content.The more western fast food intake was taken weekly,the more the proportions of the overdose of Pb was.Conclusions The six kinds of mineral element content are abnormal in grade 1 primary school students in Hefei City and the mineral elements content are correlated with intake frequency of diet.
