小儿反复呼吸道感染的临床病因相关性分析

Analysis on the correlation of clinical causes of recurrent respiratory tract infection in children

目的:探讨小儿反复呼吸道感染(RRTI)的影响因素。方法:选取50例反复呼吸道感染的患儿及在门诊体检的健康儿童48例为研究对象,对两组儿童可能导致反复呼吸道感染的因素进行检查及临床流行病学问卷调查,并对两组检查及调查结果进行Logistic回归分析。结果:过敏史、哮喘史、湿疹史、鼻炎史、荨麻疹史、母孕期吸烟史是影响反复呼吸道感染的因素。病例组患儿铁、锌、钙、铜、镁元素水平明显低于对照组(P<0.05)。结论:哮喘患儿及特应性体质患儿易发生反复呼吸道感染;合理加强儿童营养,提高抵抗力,有助于儿童反复呼吸道感染的预防及治疗。

Objective： To explore the influencing factors of recurrent respiratory tract infection （RRTI） in children. Methods： Fifty patients with RRTI and forty - eight healthy children receiving physical examination in outpatient department of the hospital were selected as study objects, the probably factors of RRT1 were measured and a clinical epidemiological questionnaire survey was performed; the detection and investigation results in the two groups were analyzed by logistic regression analysis. Results： Histories of allergy, asthma, eczema, rhinitis and urticaria, maternal smoking during gestational period were influencing factors of RRTI; the levels of iron, zinc, calcium, copper and magnesium in case group were statistically significantly lower than those in control group （ P 〈 0.05 ） . Conclusion： RRTI easily occurs in children with asthma and atopic constitution; strengthening nutrition reasonably and improving resistance are helpful to prevent and cure RRTI in children.
