Relationship between job stress and musculoskeletal disorders among the personnel of rescue groups: Structural equation modeling

摘要

Background: Job stress is considered as the most recognized health threatening in workers. Objective: The present study aimed to investigate the relationship between job stress and musculoskeletal disorders among personnel of rescue groups. Method: This descriptive analytical and cross-sectional study was conducted on 114 personnel of rescue groups including firefighters and personnel of emergency and Red Crescent in Qazvin. Data were collected using the Nordic questionnaire and job stress (HSE-Q). Structural Equation Modeling (SEM) was used to investigate the relationship between job stress and musculoskeletal disorder. The data were analyzed using the LISREL software version 8.8. Results: Job stress related to communication was found more frequent than other domains. In assessing of musculoskeletal disorders, low back devoted more prevalent (53.5%) than the neck and shoulders. A significant correlation was found between job stress and prevalence of disorders. Conclusions: According to the results of this study, job stress predicts 10% of the prevalence of musculoskeletal disorders among the personnel of rescue groups. Therefore, musculoskeletal disorders can be reduced 10% by management and controlling factors that affect job stress among workers.
