Integridade respiratória é prejudicada em tabagistas passivos adultos expostos em ambiente domiciliar

Abstract

AbstractObjective:To analyze the respiratory integrity of adult passive smokers exposedin home environment.Methods: A total of 56 volunteers, divided into passivesmokers group (GPS; n = 29) composed of family members of smokers and acontrol group (CG; n = 27) with no history of exposure. Initial evaluation wasperformed which consisted of personal data, anthropometric, blood pressure(BP), heart rate, peripheral oxygen saturation, respiratory rate. Then a question-naire was administered to respiratory diseases, measured the carbon monoxidelevel in exhaled air and spirometry was performed.Results:Higher BP valueswere observed in the GPS. The GPS showed lower spirometric values in forcedexpiratory volume in one second (p <0.0342) and forced vital capacity (p <0.0291).Regarding the intensity of the symptoms we observed significant difference inthe symptom related to itchy nose, in which the GPS reported higher intensity(p <0.002). Higher intensity was also reported in the GPS symptom in breathingmore difficult in places that have a lot of dust or when the weather changes symp-tom (p <0.0001).Conclusion:Passive smokers presented impairment in theirrespiratory health characterized by a greater intensity of respiratory symptomsand alterations in lung function
