永川区学龄前儿童微量元素参考值范围的建立及应用

Trace Elements in Preschool Children in Yongchuan Area and the Scope of Application of the Established Reference Value

目的：探讨永川区学龄前儿童末梢血微量元素的参考值范围及其在儿童预防保健中的意义。方法：选取2013年期间到我院儿保科进行健康体检的学龄前儿童1 438例,按年龄分为5组,分别为0-1岁,1-2岁,2-3岁,3-4岁和4-7岁,记录铜、锌、钙、镁、铁5种微量元素的结果,用统计学原理建立参考值范围,并与厂商给定的参考范围进行比较分析。结果：铁、锌、钙浓度明显低于厂商给定参考值范围,铁元素的含量具有显著性别差异（P〈0.05）,锌、铁含量0-1岁最低,随着年龄增大而逐渐增高,钙呈相反趋势,年龄越小,含量越高。结论：本研究发现永川区铁、锌、钙3种元素具有明显地区差异,通过本地区微量元素参考范围的建立,使其能够更加适合本地区学龄前儿童的生长发育,为临床医生做好营养及预防保健工作提供指导。

Objective：To investigate the trace elements in Yongchuan District preschool children peripheral blood reference ranges and in the significance of children＇s preventive health care.Methods：Preschool children during 2013 to the department of child health selection of our hospital for health examination in 1 438 cases,divided into 5groups by age,respectively,for 0-1years old,1-2years old,2-3years old,3-4years old and 4-7years old,record of copper,zinc,calcium,magnesium,iron 5kinds of trace element results,to establish the reference range by using the statistics theory,the reference range and manufacturers given comparative analysis.Results：Iron,zinc,calcium concentration was below the manufacturer given reference value range,with significant gender differences in the content of blood iron（P〈0.05）,0-1years old was the lowest content of zinc,iron,as the age gradually increases,the blood calcium were on the contrary,the younger,the higher the content of.Conclusion：This study found that the Yongchuan area of iron,zinc,calcium and 3kinds of elements have obvious regional differences,through the establishment of the reference range of trace elements in the region,to make it more suitable for preschool children in the local area＇s growth and development,to provide guidance for clinicians to good nutrition and health.
