Introduction: Musculoskeletal disorders are a class of occupational injuries that have high prevalence and are important causes of disability in developing countries. The aim of this study was to investigate the relationship between risk and prevalence of musculoskeletal disorders in a household manufacturing company. Methods: This cross-sectional descriptive-analytical study conducted on100 workers including 15 workers from foam injection workshop, 17 from molding workshop, 17operators of presses, 17from packaging unit, 17from cutting unit, and17 operators of rivets. The Nordic questionnaire was used to record the symptoms of musculoskeletal disorders in wrist, elbow, shoulder, neck, and back. Then, working postures were recorded and evaluated by the LUBA method. The employees signed an informed consent and their data were treated strictly confidential. The obtained data were analyzed by SPSS version 20. Results: Most of the musculoskeletal disorders based on Nordic questionnaire were observed in the wrist (15 cases), neck (15cases) and shoulder (14 cases). A significant relationship was found between musculoskeletal disorders and age (p<0.001) and job experience (p<0.05). Highest risk of musculoskeletal disorders as measured by LUBA method was related to rivet unit (risk level equal to 4) and least level of risk related to foam injection unit (risk level equal to 2). Conclusion: The results of this study showed that household manufacturing workers are at risk of developing musculoskeletal disorders. Therefore, ergonomic interventions such as work station design based on ergonomic principles, the use of ergonomically designed tools, and education of workers should be considered.
