目的:了解目前广东河源地区儿童体内钙、铁、镁、锌、铜、铅6种微量元素含量情况,为儿童科学合理补充微量元素提供依据。方法:采用原子吸收光谱法对22554例儿童进行钙、铁、镁、锌、铜、铅6种微量元素检测,并按0~1岁、1~2岁、2~3岁、3~4岁、4~5岁、5~6岁、6~7岁、7~8岁八个年龄组对检测结果进行统计比较、分析。结果:广东河源地区儿童钙、铁、镁、锌、铜5种微量元素缺乏率分别为0.16%、37.35%、42.66%、26.76%、0.33%,其中血铅的中毒率为1.60%。除镁外,钙、铁、锌、铜缺乏率和铅中毒率在不同性别间比较,均无统计学意义(P>0.05);钙、铁、镁、锌、铜5种元素各年龄组间比较差异有显著性(P<0.05)。血铅的含量在5~6岁年龄组检出率最高,为2.60%。结论:河源地区儿童镁缺乏最为严重,其次为铁和锌,铅中毒较少。提示各级政府医疗卫生保健单位应加强儿童保健,加大儿童微量元素监测力度,做到科学合理补充微量元素,以保证儿童健康成长。
OBJECTIVE: To understand the content of 6 trace elements of calcium, iron, magnesium, zinc, copper and lead in children in Heyuan of Guangdong Province at present, and provide the basis for scientific and rational supplementation of trace elements. Methods: Twenty-five children with calcium, iron, magnesium, zinc, copper and lead were detected by atomic absorption spectrometry. Trace elements were detected by atomic absorption spectrometry in 0-1, 1-2, 2--3 and 3-4 years , 4 to 5 years old, 5 to 6 years old, 6 to 7 years old, 7 to 8 years old eight groups of age for statistical comparison of test results, analysis. Results: The deficiencies of five trace elements such as calcium, iron, magnesium, zinc and copper in Heyuan children were 0.16%, 37.35%, 42.66%, 26.76% and 0.33%, respectively. The lead poisoning rate was 1.60%. In addition to magnesium, calcium, iron, zinc, copper deficiency rate and lead poisoning rate in different genders were not statistically significant (P> 0.05); calcium, iron, magnesium, zinc, The difference was significant (P <0.05). Blood lead levels in the 5 to 6 age group the highest detection rate of 2.60%. Conclusion: The magnesium deficiency in Heyuan children is the most serious, followed by iron and zinc, lead poisoning is less. Prompt medical health care units at all levels should strengthen child health care, increase monitoring of trace elements in children, science and reasonable to do trace elements to ensure the healthy growth of children.
