Background: Musculoskeletal disorders in developing countries are considered as main cause of occupational disorders and disability and highly associated with socioeconomic burden to individual, organization and society in general view. The purpose of this study was to determine the prevalence of musculoskeletal disorders and associated risk factors among Iranian steel workers.


Methods: In a cross-sectional study, 1439 questionnaires were provided from 1984 randomly selected workers of four Iranian steel industries. Data of musculoskeletal disorders was gathered by means of standardized Nordic self-reporting questionnaire. Demographic and work related data were collected into the check list.


Results: Out of 1984 individuals, 1439 questionnaires returned and mean age of study workers was 37.23±8.74 years old. Among workers, 46.3% in the past week and 61% in the last year claimed one of musculoskeletal disorders in their bodies. Lumbar, knee(s) and neck areas had the most common musculoskeletal disorders. Musculoskeletal disorders had significant association with the job time of work and BMI.


Conclusion: Musculoskeletal disorders in Iranian steel industries happened in high rate. Ergonomic interventions strategies into the workplaces must be focused to eliminate environmental hazards such as apposition on the time of work and manual handling of heavy loads.
