Abstract
This study aimed to investigate the effects of smoking intensity on mucociliary transport and physical activity levels, comparing smokers and non-smokers. A total of 52 current smokers and 30 healthy non-smokers were included in the examination. Succharin transit time (STT) in the mucociliary system, lung function, and smoking history were assessed in all participants. Results indicated no significant difference in STT between light smokers (15 cigarettes/day) and nonsmokers, with both groups exhibiting similar mean transit times (9-11 minutes; p = 0.8). However, heavier smokers (>25 cigarettes/day) demonstrated prolonged STT compared to non-smokers. Additionally, there was no significant difference in daily step counts between smoker and non-smoker groups (p > 0.05). Further analysis revealed that physical activity levels (PADL), as measured by waist-worn pedometers over six days, did not significantly correlate with smoking history, packyear index, or years of smoking among the general smoker group (r = 0.23; p > 0.09). However, among moderate and heavy smokers, there was a significant negative association between STT and PADL (r = 0.55; p < 0.02), indicating reduced mucociliary function in individuals with higher smoking intensity. In conclusion, moderate and heavy smokers exhibited impaired mucociliary function compared to light smokers and non-smokers, suggesting a detrimental effect of smoking intensity on respiratory health. These findings underscore the importance of considering smoking habits and intensity when assessing mucociliary transport and respiratory function
