1 383例儿童锌铁铜镁钙检测结果分析

目的了解门诊中儿童体内锌、铁，铜、镁、钙的含量，探讨其缺乏或过多的综合防治措施，以及它们相互之间的关系。方法以儿科门诊体检的1383例0～10岁儿童为检测对象，用原子光谱仪测量，微机统计分析。结果不同性别儿童的血铁、锌、钙、镁、铜含量差异无统计学意义（P〉0.05）；不同年龄儿童的钙、镁浓度差异无统计学意义（P〉0．05）；而不同年龄儿童的铁、锌浓度差异有统计学意义（P〈0．01）。相关分析显示，血锌与血铜和血铁水平呈明显正相关（分别为r=0．315，P〈0．01；r=0．235，P〈0．01），血铁与血铜呈明显正相关（r=0．378，P〈0．01）。1岁以内儿童锌缺乏最为显著，达60．2％，其余依次为缺铁19．6％，缺铜5．4％，缺钙3．2％，无1例镁缺乏。结论婴幼儿为生长发育最快时期，易缺乏锌、铁元素，且年龄越小，越易缺乏。

Analysis of zinc, iron, cuprum, magnesium and calcium in 1 383 children

Objective To investigate the content and relationship of some microelements and macroelement of children in out-patient clininc,to explore approaches of prevention and treatment.Methods Serum content of zinc,iron,cuprum,magnesium and calcium of 1 383 children during 0-10 years were measured by atonic spectrograph and analyzed statistically by comuter soft ware.Results There was no significant difference between the serum content of Fe,Zn,Ca,Mg and Cu in male and female children(P>0.05).There was no significant difference between the serum content of Ca and Mg in different age(P>0.05).There was significant difference between the serum content of Fe and Zn in different age(P<0.01).There was significant correlation between the serum content of Zn and Cu,Zn and Fe(r=0.315,P<0.01;r=0.235,P<0.01).There was significant correlation between the serum content of Fe and Cu(r=0.378,P<0.01).The rate of Zn deficiency in infant was predominant(60.2%).The rate of Fe deficiency was 19.6%.The rate of Cu deficiency was 5.4% and the rate of Ca deficiency was 3.2%.The serum content of Mg in all children was normal.Conclusion Growth and development of children in infancy and toddler's age is very fast.It is easy to suffer from zinc and iron deficiency,the younger,the easier.
