Abstract
The aim of this comparative study was a comprehensive analysis of respiratory health in young smokers. Methods. An acoustic analysis of respiratory sounds, spirometry, the Fagerstrom Test for Nicotine Dependence, and the Questionnaire of the European Community for Coal and Steel (ECCS) on respiratory symptoms were used in this study. Results. The study involved 158 young subjects aged 18 to 19 years (mean age, 18.4 ± 1.1 years; 91 males). A significant difference in spirometric parameters, prevalence of symptoms of chronic bronchitis and the acoustic work of breathing (AWB) was found between smokers and non-smokers. Nicotine dependence was evaluated as weak with lower to moderate exhaled CO levels. However, motivation to continue smoking was moderate or higher; spirometric and AWB parameters were significantly lower in smokers compared to non-smokers. Conclusion. The acoustic analysis of respiratory sounds could be used for clinical and functional evaluation of respiratory status, predicting COPD development and smoking control along with spirometry, specific questionnaires and smoking status assessment.
