500例儿童3种微量元素检测结果现状分析

The Analysis of Current Situation on Det ecting Microelements Contents of 500 Child ren

目的:分析不同年龄儿童微量元素的缺乏情况,以便及时了解儿童营养健康状态,提高儿童保健水平。方法:将取自沈阳市和平区妇幼保健所的500例标本,分为3个年龄组,检测10μl静脉血或末梢血中的三种微量元素的含量。采用天津兰标电子科技发展有限公司所生产的微量元素分析仪,测定原理为电化学法。结果:男女儿童之间各微量元素含量无明显差异,各年龄组别之间微量元素含量也无明显差异(P>0.05)。3个年龄段的儿童不同程度的缺乏各种微量元素,其中以钙和锌的缺乏明显,而铁缺乏在各年龄段儿童中均不明显。各个年龄段儿童微量元素的缺乏情况又不一样,5岁以上儿童缺锌、缺铁明显,3～5岁儿童缺钙、缺锌明显,0～3岁儿童钙、铁、锌缺乏均不明显。结论:合理膳食及儿童生长发育阶段定期检测微量元素含量可有效预防因微量元素缺乏引起的相关临床疾病。

Objective：To deter min e the contents of zinc,calcium and iron in per ipheral blood of children from zero to s ix years old and analyze the condition o f microelement deficiency.So as to unde rstand nutrition health of children in t ime and elevate the level of children ca re.Method：500 samples were collected f rom the Women and Children Hospital of H eping region of Shenyang and divided int o three age groups.The content of micro element in 10 μl venous blood or periphe r al blood was detected by electrochemical analysis.Results：There was no signifi cant difference of the microelement cont ents between boys and girls,and also am ong three age groups（P〈0.05）.Each kind of microelement was deficient to differ ent degree in three age groups,in which calcium and zinc deficiency was obvious while asiderosis was not obvious in eac h age group.The deficiency condition of children microelement among three age g roups was not the same,in which zinc an d iron deficiency were obvious in childr en above five years old,while calcium and zinc defi ciency was obvious in children from thre e to five years old.Three kind of microelements were not obvious in aero to three years old.Conclusion： Therefore,rational diet and regular microelement detection during growth and development period of children can preven t correlative clinical problems caused b y microelement deficiency.
