Abstract: 

Background: Train drivers are relatively exposed to vehicle fumes during work which can induce respiratory problems. Therefore, pulmonary function tests in train drivers were compared with matched control subjects in this study.
Methods: Pulmonary function tests (PFT) were measured in a sample of 46 Iranian train drivers in Mashhad city and 55 control subjects with similar age and gender and having other jobs from the general population using a standard spirometer.
Results: All PFT values (except MMEF and MEF75) in train drivers were significantly lower compared to control group (p<0.005 to p<0.001). A total of 17 (37%) of train drivers showed PFT pattern of obstructive respiratory disorders (15% mild, 13% moderate and 9% sever) and 7 (15%) of them restrictive lung abnormalities (2% mild, 9% moderate and 4% sever). The values of MMEF, PEF, MEF50 and MEF25 were significantly lower while FVC was higher in train drivers with obstructive pattern compared to those with restrictive pattern (p<0.05 to p<0.001).
Conclusion: Theses results showed that train drivers have a relatively higher risk of work related respiratory disorders specially for obstructive pulmonary disorders.
