Background: The aim of this study was to evaluate respiratory problems via pulmonary function testing in cement transport workers at Incheh Borun border in northeast of Iran in 2016. Methods: The study was conducted on 358 male workers. All subjects were evaluated for respiratory symptoms via pulmonary function testing and completion of the American Thoracic Society questionnaire. Results: Mean age of workers was 34.8±12.87 yr (age range 16–79 yr). Mean duration of employment was 6.1±4.36 yr. Most workers (75.4%) were illiterate or had elementary education. In addition, 56 (15.6%) subjects were smokers. Only three individuals (0.3%) had obstructive pattern. There was a significant relationship between age of workers and frequency of respiratory problems (P<0.05). Conclusion: It is necessary to educate the workers about the health and safety regulations and use of personal protective equipment in workplace. In addition, periodic evaluation of respiratory function could help protect workers from developing occupational diseases.
