目的了解本地区学龄前儿童微量元素的含量,为合理补充微量元素提供科学依据。方法采用原子吸收光谱仪检测686例4岁~6岁畲汉两族儿童全血钙、镁、铁、铜、锌、铅6种微量元素的含量,并对年龄、民族进行差异性分析。结果 6种微量元素中,缺钙率最高,达到14.0%,3个年龄组随年龄的增长而逐渐增高(P<0.01),其次是缺锌率,达7.3%,并且随年龄的增长而逐渐降低(P<0.01),缺铁率有3.2%,其它微量元素情况基本良好。汉族和畲族之间6种微量元素含量差异无统计学意义(P>0.05)。结论儿童应定期去医院检测微量元素含量,在医生的指导下制定个性化的营养处方和生活习惯的建议,保证各种营养均衡摄入。
Objective To understand the content of trace elements in preschool children in this area and provide a scientific basis for the rational supplementation of trace elements. Methods The content of 6 trace elements of calcium, magnesium, iron, copper, zinc and lead in whole blood of 686 children aged 4 to 6 years in Shehan and Han nationality were detected by atomic absorption spectrometry, and the age and ethnic differences were analyzed. Results Among the six trace elements, the calcium deficiency rate was the highest, reaching 14.0%. The three age groups gradually increased with age (P <0.01), followed by the zinc deficiency rate (7.3%), and gradually decreased with age Decreased (P <0.01), iron deficiency rate was 3.2%, other trace elements basically good. There was no significant difference in the contents of 6 trace elements between Han and Shezu (P> 0.05). Conclusion Children should regularly go to the hospital to detect trace elements, under the guidance of a doctor to develop personalized nutrition prescriptions and lifestyle recommendations to ensure a balanced intake of various nutrients.
