title: [Respiratory system reactions in children with allergies exposed to air pollution at home. Epidemiologic studies in Cracow].
abstract: The purpose of the paper was to check the hypothesis whether the domestic air quality together with level of outdoor air pollution increases the risk of allergy and whether allergy determines the occurrence of respiratory symptoms. The results of the study have shown that chronic cough was related mainly to allergy, however, chronic phlegm was linked with air quality. Wheezing independent from respiratory infections was associated in the strongest way with allergy (RR = 7.7; 4.7-12.7) and much weaker related to air quality score (RR = 1.3; 1.1-1.5). The occurrence of attacks of breathlessness was confirmed only in allergic children. Allergic rhinitis, similarly to wheezing, was related stronger to allergy (RR = 3.3; 2.5-4.4) than to air quality score (RR = 1; 1.0-1.2). Pulmonary volumes (FVC, FEV1) were not associated with air quality score, but the lower indices of FEV1/FVC and FEF25 - 75% were observed in those who were exposed to poor air quality. The results are in favor of the hypothesis, that air pollutants bring about spasm of smaller airways and it is independent from respiratory symptoms.
