Evaluation of the Risk Factors of Musculoskeletal Disorders and its Relation to the Workload of Employees at 118 Call Center in Sanandaj, Iran

Background: Maintaining the employees' health in work environments is one of the managers’ responsibilities and paying attention to the related risk factors is important. The aim of this study was to evaluate risk factors of musculoskeletal disorders and its relation to employees’ workload at 118 call center in Sanandaj, Iran. Methods: This cross-sectional descriptive-analytic study was conducted on all employees of the Sanandaj 118 call center. Nordic and NASA-TLX standard questionnaires were respectively used in order to collect the information related to the prevalence of musculoskeletal disorders and employees’ workload. Rapid Office Strain Assessment (ROSA) method was used for evaluating the ergonomic risk factors at work stations. Data analysis was performed through SPSS 16. Results: The results indicate a high mean of workload, and prevalence of musculoskeletal disorders especially in the neck and lower back. Gender, body mass index, work shift, work experience, risk level of workload and ROSA final score were significantly related with most musculoskeletal disorders. In addition, a statistically significant relationship was observed between workload score and both body mass index and work experience. Conclusion: Due to unsuitable workstations and high prevalence of musculoskeletal disorders, improving workstations must be considered. Also, utilizing interventional strategies for reducing workload dimensions associated with musculoskeletal disorders is essential.
