摘要
目的 探讨福州地区小儿锌、铜、铁、钙的营养状况及其影响因素。方法 采用原子吸收分光光度法对福州地区 80 3 5名小儿发中的锌、铜、铁及钙含量进行了测定 ;并采用SPSS软件包对发锌、铜、铁及钙含量与小儿年龄、性别、测定季节及不同年代之间的关系进行多因变量线性模型的方差分析。结果 福州地区小儿发锌、铜、铁、钙值分别为 ( x±s,μg/g) :112 9± 2 9 7、 7 70± 2 46、 45 88± 6 75、 448 7± 91 0。发锌含量受到年龄 ,头发中铜、铁、钙含量、测定年代的影响 ;发铁含量受到性别、年龄 ,头发中锌、钙含量、测定年代的影响 ;只有发锌含量和测定年代影响小儿发铜含量。发钙含量则受到年龄 ,头发中锌、铁含量、测定年代的影响。随着年代发展 ,发钙含量逐渐升高外 ,小儿头发中铜、铁含量逐步下降 ;发锌含量自 1993年起有所上升 ,在 1999～ 2 0 0 0年又开始下降。结论 福州地区小儿锌、铜、铁、钙营养状况仍处于一个较低水平 ,提倡平衡膳食 。
Objective To investigate the s tatus of zinc,copper,iron and calcium and the influential factors among the ch il dren in Fuzhou district Methods The atomi c absorption spectrophotometry was used in measuring hair concentration of zinc , copper,iron and calcium among a total of 8 035 children in this region,While t he SPSS software package(version 8 0)was employed for data analysis The variance a nalysis of Multiple Dependent Variable Linear Model was performed to determine t he relationship between the hair contents of zinc,copper,iron and calcium,and their relations with ages,sexes,measuring seasons and years Results Of the 8 035 subjects,the hair contents of zinc ,c opper,iron and calcium(±s,μg/g)was 112 9±29 7,7 70±2 46 ,45 88 ±6 75,448 7±91 0 respectively The hair zinc content was influenced by age s,hai r concentration of copper,iron and calcium and measuring years;the hair iron co n tent was influenced by sex,age,hair concentration of zinc and calcium and meas ur ing years;the hair copper content was influenced by hair concentration of zinc a nd measuring years;the hair calcium content was influenced by ages,hair concent r ation of zinc and iron and measuring years As time went on,the hair calcium co nt ent increased,while the hair content of iron and copper decreased The hair zin c content had been increased since 1993,but was decreased during 1999～2000 Conclusions It was concluded that the status of zinc,copper,iron and calcium of the children in this region was still in a lo we r level The improvement of the status of these trace elements is still one of the most crucial health problems in childhood
