Objective: The aim of this study was to detect small airway pathologies in cleaning workers at an early stage by impulse oscillometry (IOS). Methods: The study was cross-sectional and involved 121 cleaning workers and 123 controls between September 2022 and January 2023. Results: Airway disease-related measurements (R5%, R20 %, R5-20%, AX, Fres) determined by IOS werestatistically significantly higher in cleaning workers. The mean and median values of FEV1/FVC (%), PEF (%), MMEF (%), FEF25 (%), and FEF75 (%) were significantly lower in cleaning workers compared to the control group (p < 0.05). Using General Linear Models (GLM) adjusted for work duration, sex, age, BMI, and smoking, occupational differences in lung function and IOS were not significant, showing these factors explain the effects. Conclusion: IOS can be used for the early detection of airway diseases.
