摘要
目的探讨儿童反复呼吸道感染(RRTI)与血微量元素含量的关系。方法用北京博晖BH5100型和BH2100型原子吸收光谱仪分别检测557例儿童反复呼吸道感染(RRTI)患儿血中铜、锌、钙、镁、铁及铅的含量,并与557例健康对照组作比较。结果观察组患儿血中锌、铁、钙含量明显低于对照组,差异有统计学意义(P<0.05),而0～≤6岁观察组患儿血铅的水平明显高于对照组,差异有统计学意义(P<0.01)。只有大于3～≤6岁观察组患儿血中镁的含量明显低于对照组(P<0.01)。结论 RRTI与血中锌、铁、钙的缺乏及铅暴露的水平密切相关。及时、合理地补充微量元素,维持体内微量元素之间的平衡,有助于提高儿童的免疫力,降低儿童RRTI的患病率。
Objective To study the relationship between recurrent respiratory tract infections（RRTI） in children and blood trace elements.Methods Blood levels of Cu,Zn,Ca,Mg,Fe and Pb were detected by BH5100 plus and BH2100 atomic absorption spectrometer in 557 cases of children with RRTI（RRTI group）,and they were compared to the results in 557 cases of healthy control group.Results Blood levels of Zn,Fe and Ca in RRTI group were significantly lower than those in control group（P〈0.05）.But among children of 0-≤6 years old,blood level of Pb in RRTI group was significantly higher than that in control group（P〈0.01）.Only in children of 〉3-≤6 years old,blood level of Mg in RRTI group was significantly lower than that in control group（P〈 0.01）.Conclusion RRTI might be closely related to deficiency of blood Zn,Fe and Ca and the exposure level of Pb.Timely and reasonable supplement of trace elements and maintaining the balance between trace elements might be helpful to improve children’s immunity and reduce the prevalence rate of RRTI in children.
