目的:了解丽水市儿童体内铜、锌、钙、镁、铁5种微量元素水平,为更好地指导本地区儿童合理补充微量元素提供科学依据。方法:使用火焰原子吸收法检测5种微量元素,对本地3个年龄段1428名儿童全血铜、锌、钙、镁、铁检测结果做回顾性分析。结果:5种微量元素含量在不同性别之间差异均无统计学意义(P>0.05);5种微量元素中,锌总缺乏率最高,达到19.05%,且3个年龄段锌元素缺乏率差异有显著统计学意义(P<0.05),其次是铁缺乏,达到16.80%,钙总缺乏率较低,为3.64%。结论:丽水市儿童易出现锌、铁微量元素失衡,尤其0周～3周岁婴幼儿锌元素缺乏率高,应对儿童定期检测微量元素,及时采取措施,预防微量元素缺乏。
Objective: To understand the levels of 5 trace elements of copper, zinc, calcium, magnesium and iron in children in Lishui city and to provide a scientific basis for better guiding children in this area to rationally supplement trace elements. Methods: Five kinds of trace elements were detected by flame atomic absorption spectrometry. The results of the detection of whole blood copper, zinc, calcium, magnesium and iron in 1428 children in three local age groups were retrospectively analyzed. Results: There was no significant difference in the contents of five trace elements among different sexes (P> 0.05). Among the five trace elements, the total zinc deficiency rate was the highest (19.05%), and there was no significant difference in the three zinc deficiency rates There was significant statistical significance (P <0.05), followed by iron deficiency, reaching 16.80%, the total calcium deficiency rate was 3.64%. Conclusion: Lishui City children prone to zinc, iron and trace elements imbalance, especially 0 weeks to 3 years old infants zinc deficiency rate is high, children should be regularly detected trace elements, timely measures to prevent the lack of trace elements.
