A Cross-Sectional Study of Pulmonary Function Test Using FEV1, FVC, and FEV1 / FVC Ratio Among Commercial Three-Wheeler Drivers Aged 18-60 Years in Guwahati
Abstract: This cross-sectional study assessed pulmonary function among 150 healthy male commercial three-wheeler drivers aged 18 to 60 years in Guwahati to examine the relationship between occupational exposure to vehicular air pollution and respiratory health. Commercial three-wheeler drivers represent a vulnerable occupational group due to prolonged exposure to traffic-related pollutants in semi-open vehicles. Pulmonary function was evaluated using spirometry, with key parameters including forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio. Participants were grouped according to duration of occupational exposure, less than 10 years and more than 10 years. Statistical analysis showed significantly lower pulmonary function values among drivers with longer exposure duration. FEV1, FVC, and FEV1/FVC ratio declined progressively across increasing age groups, with strong negative correlations observed between pulmonary function measures and both age and driving experience. Daily driving hours also showed a weak negative association with selected lung function parameters. Type of vehicle and alcohol use did not show significant associations with exposure duration. The findings indicate that prolonged occupational exposure to vehicular pollution may contribute to declining respiratory function among commercial three-wheeler drivers, highlighting the need for occupational health monitoring and preventive measures in this population.
