娄底地区1517例儿童微量元素检测分析

Detection and Analysis of Trace Elements in 1517 Children of Loudi Area

目的:通过对娄底地区儿童的静脉全血微量元素(铜、锌、铁)、常量微量元素(钙、镁)等5种元素含量进行分析,了解幼儿健康情况,指导幼儿合理膳食,预防疾病的发生,及时补充幼儿生长发育所需要的元素。方法:选取2019年1-7月对来娄底市中心医院进行体检的1517例儿童为研究对象,按年龄分为婴儿组、幼儿组、学龄前组,分析三组铜、锌、铁、钙、镁元素情况。结果:铜、钙元素含量随着年龄的增长呈减少趋势,差异有统计学意义(P<0.05);锌、铁元素含量随着年龄的增长呈增加的趋势,差异有统计学意义(P<0.05);三组镁元素含量比较稳定,差异无统计学意义(P>0.05)。未检测出镁元素缺乏;三组铜元素缺乏比较,差异无统计学意义(P>0.05);锌、铁元素缺乏随着年龄的增长都有改善,而钙元素的缺乏则随着年龄的增长呈上升趋势,差异有统计学意义(P<0.05)。结论:儿童处于生长发育的旺盛期,微量元素缺乏普遍存在,家长和医生要引起重视,根据不同年龄段的特点采取不同的干预措施,合理膳食补充营养,定期对儿童微量元素含量进行监测,避免过多或不足引起疾病,确保儿童健康成长。

Objective:To analyze the content of 5 elements including trace elements(Cu,Zn,Fe)and macroelements(Ca,Mg)in venous whole blood of children in Loudi area,understand the health status of children,guide a reasonable diet of children,prevent the occurrence of diseases,and timely supplement the elements required for growth and development of children.Methods:A total of 1517 children who received physical examination in Loudi Central Hospital from January 2019 to July 2019 were selected as the study subjects.According to age,they were divided into infancy group,early childhood group,and preschool age group.The copper,zinc,iron,calcium and magnesium elements in three groups were analyzed.Results:The contents of copper and calcium elements decreased with the increasing age,and the differences were statistically significant(P<0.05).The contents of zinc and iron elements increased with the increasing age,and the differences were statistically significant(P<0.05).The contents of magnesium element in the three groups were relatively stable,and the difference was not statistically significant(P>0.05).No magnesium deficiency was detected;There was no statistically significant difference in copper elements among the three groups(P>0.05).Zinc and iron deficiency was improved with the increasing age,while calcium deficiency increased with the increasing age,and the difference was statistically significant(P<0.05).Conclusion:Children are in the period of vigorous growth and development.The deficiency of trace elements is common in children,and requires the attention from parents and doctors.It is suggested to take different intervention measures according to the characteristics of different age groups,supplement nutrition through rational diet,regularly monitor the contents of trace elements in children,and focus on prevention.Scientific and reasonable supplementation can avoid the disease caused by the element excessiveness or deficiency,and ensure the healthy growth of children.
