儿童血铅水平及微量元素缺乏的临床调查分析

摘要

Objective To study the blood lead levels and the clinical manifestations of deficiency of trace elements in chil-dren. Methods 1260 children underwent health examination in our hospital from December 2012 to December 2014 were selected and divided into three groups, group A(0~1 year old), group B(1~3 years old), and group C(over 3 years old) with 420 cases in each. Lead and cadmium analyzer and trace elements analyzer were used for the detection of the levels of such trace elements as peripheral blood lead, iron, zinc and calcium in all the children. Results The difference in the levels of blood lead and other trace elements between female and male children was not statistically significant (P>0.05). Deficiency of trace elements existed in all the three groups in varying degrees. 57.14% of the children (270/420) lacked calcium. No lead poisoning occurred in all the children. Conclusion Deficiency of trace elements exists in children of different ages, so the children's dietary guidance should be strengthened.%目的：研究分析儿童血铅水平和微量元素缺乏引起的临床表现。方法整群选取该院2012年12月—2014年12月健康体检的儿童1260例，将所有儿童根据年龄分为A、B、C 3组，各420例。 A组为0～1岁，B组为1～3岁，C组为＞3岁，所有儿童均给予相同的铅镉分析仪和微量元素分析仪进行检测，主要为末梢血的铅、铁、锌、钙微量元素的含量。结果所有儿童的血铅水平及微量元素缺乏情况在性别上对比，差异无统计学意义（P＞0.05）；3组儿童均存在不同程度的微量元素缺乏，其中缺钙最多达到57.14%（270/420），所有儿童均未出现铅中毒。结论不同年龄段儿童均会存在一定程度的微量元素缺乏现象，应注意加强儿童饮食指导。
