Background: Workers in shipyard companies are exposed to different respiratory hazards. The present case-control study was designed to evaluate pulmonary function tests and respiratory symptoms among shipyard workers in Asaluyeh city in Southwest Iran. Material and Method: Between March and October 2015 we recruited participants from two separate populations: shipyard workers as cases and office workers from the same shipyard company, who are not exposed to the same respiratory hazards, as controls. History was obtained from all participants and they all underwent physical examination and spirometry. Results: Respiratory signs and symptoms were present in a significantly higher number of shipyard workers compared to the unexposed office workers. Similarly, there were significant spirometric differences between cases and controls. Conclusion: It seems that workplace hazards play a more significant role than other factors such as air pollution in development of respiratory diseases, and future studies for investigating respiratory symptoms, pulmonary function parameters, biological monitoring and measurement of respiratory hazard need to be performed.
