福建长乐市学龄前儿童末梢血矿物质检测结果分析

Analysis of Mineral Substances Levels in Peripheral Blood of Children Aged 3～6 years in Changle city Fujian Province

为了解福建省长乐市学龄前儿童体内矿物质钙、镁、铁、锌、铜的含量与年龄和性别的关系,探讨防治其缺乏的综合措施,利用BH 5100型原子吸收光谱仪对4 231例学龄前儿童末梢血中钙、镁、铁、锌和铜元素进行了检测,采用SPSS 17.0软件进行统计分析。结果表明,该地区学龄前儿童末梢血锌元素含量有3个年龄组低于正常值;其中锌、铁元素缺乏严重,缺乏儿童分别占总样本的61.92%和34.60%;末梢血中矿物质含量在部分年龄组和性别之间比较差异有统计学意义(P<0.05)。提示该地区学龄前儿童铁、锌元素缺乏明显,应定期检测并加强膳食中微量元素铁和锌的补充,保证儿童的健康成长。

To investigate prevalence of mineral substances （ contents in calcium, magnesium, iron, zinc and copper） in peripheral blood of children aged 3 - 6 years in changle city fuJian provine, contents of 5 minerals substances in peripheral blood of 4 231 children aged 3 - 6 years were detected by atomic absorption spectrometry. The data were analysis with SPSS software. The results shewed that three age groups of zinc content in peripheral blood were lower than reference value. Serious zinc and iron deficiency were common among 4 age groups. The deficiency rate of zinc was 61.92% , that of iron was 34. 6%. The content of mineral substances Levels in peripheral blood there were significant difference among partial age groups and two genders （P 〈 0.05 ）. It deficiency of mineral substance was existed in changle＇s preschool children such as iron, zinc especially.
