目的 了解包头地区0～12岁不同年龄段儿童全血中锌、铁、镁、铜4种矿物质元素营养水平及变化趋势。方法 0~12岁健康体检的儿童中随机抽样918例, 利用SPSS 16.0软件包进行统计分析。结果 4个年龄阶段Zn、Fe均有较高的缺乏率;随年龄的增长, 锌元素水平逐渐增加, 铁元素水平整体呈上升趋势, 6岁后上升更加明显;Cu和Mg元素缺乏率较低;镁元素水平随年龄增长呈上升趋势; 0～6岁间儿童体内铜元素的水平变化不明显, 6岁后含量明显下降。结论 包头地区儿童4种矿物质元素的缺乏顺位依次为:锌、铁、铜、镁;儿童4种矿物质元素诊断标准应按年龄阶段划分。

Four mineral element level changes trend and comparison of difference in 918 cases of children of different ages in Baotou.

Objective To understand nutrition levels and change trends of zinc(Za), iron(Fe), magnesium(Mg), copper(Cu) in the whole blood of children aged 0~12 in Baotou. Method A total of 918 children aged from 0 to 12 years old for the healthy examination were randomly selected, and statistical analysed using SPSS 16.0 software packages. Results Lack rate of Zn and Fe in 4 age stages were higher.Along with the growth of the age, the content of zinc increased gradually.Iron level as a whole was on the rise, and rised more sharply after 6 years old.Cu and Mg lack of rate were low.Mg level was on the rise along with the age growth.Between 0~6 years old children's copper level change was not obvious and decreased obviously after 6 years old. Conclusions Lack sequence of children in Baotou is as follows:zinc, iron, copper, magnesium.Diagnostic criteria of 4 mineral elements of children should be divided according to age stage.
