目的了解天河区0~5岁儿童体内铁、锌、钙、铅元素的含量,探讨其缺乏的综合防治措施,为儿童合理补充微量元素提供参考。方法对2009年在本院儿保门诊体检的1 326例0~5岁儿童,采用北京博晖BH5100型原子吸收光谱仪测定末梢血铁、锌、钙、含量,用BH2100血铅分析仪测定血铅。结果 1 326例缺乏率比较排第一的为锌(29.40%),铁(26.21%),其次为钙(15.72%)。铅平均值从0~1岁的56.5μg/L上升到5岁组的88.3μg/L。结论 0~5岁是儿童生长发育的最快时期,易发生锌、铁、钙元素缺乏,且年龄越小越易缺乏,而铅元素则随年龄增加而上升。今后要加强健康教育,指导父母正确营养搭配,合理膳食。提示儿童保健工作者应根据不同年龄段间采取不同的干预措施。
Objective To understand the contents of iron, zinc, calcium and lead in children aged 0 ~ 5 years in Tianhe District, and to explore the comprehensive prevention and control measures for them, so as to provide a reference for the rational supplementation of trace elements in children. Methods A total of 1326 children aged 0 ~ 5 years undergoing pediatric physical examinations in our hospital in 2009 were tested for blood iron, zinc and calcium contents by BH-BH5100 atomic absorption spectrometer in Beijing and blood lead contents were measured by BH2100 blood lead analyzer . Results Among the 1 326 cases, the first one was zinc (29.40%), iron (26.21%), followed by calcium (15.72%). The average lead level increased from 56.5 μg / L at 0 to 1 year old to 88.3 μg / L at 5 years old group. Conclusion 0 ~ 5 years old is the fastest growth and development of children, prone to zinc, iron, calcium deficiency, and the younger the more vulnerable to the lack of lead while the element increases with age. In the future, health education should be strengthened to guide parents to properly nutrition and reasonable diet. Hint Children’s health workers should take different interventions according to different age groups.
