1 353名学龄前儿童血液中部分矿物质含量调查分析

目的:调查金坛市学龄前儿童血中铁、铜、锌、钙和镁的含量,为进一步探讨矿物质含量与学龄前儿童智力和行为的关系提供基础资料。方法:调查城区、城郊结合部、乡镇3家幼儿园共1353名学龄前儿童,用原子吸收光谱仪进行全血铁、铜、锌、钙和镁的检测。结果:1353名学龄前儿童缺锌、缺钙和缺铁的比例较高,缺乏率分别为38.14%、34.29%和24.32%,铜和镁的缺乏率分别为0.67%和0.61%。结论:金坛市学龄前儿童矿物质缺乏的现象比较普遍,营养状况有待于进一步改善,矿物质与智力及行为的关系值得进一步研究。

Investigation on haemal mineral status among 1 353 preschool children

Objective To assess the prevalence of haemal minerals(Fe,Cu,Zn,Ca,Mg) among preschool children in Jintan and provide basic information to further identify risk factors and health outcome associated with minerals in this cohort.Method A total of 1 353 male and female preschool children,aged 4-6 years,from 3 kindergarten cohorts(central city,suburbs,and countryside) in Jintan city participated in the study.Blood concentrations of Fe,Cu,Zn,Ca and Mg were determined by atomic absorption spectrophotometer.Results There were high deficiency rates in Zn(38.14%),Ca(34.29%),and Fe(24.32%),but only 0.67% and 0.61% have Cu and Mg deficiency respectively.Conclusion The data show that preschool children in Jintan city have in adequate mineral status which should be improved.Further study on identifying risk factors and health outcome associated with minerals is needed.
