Abstract
Background: Due to the prevalence of musculoskeletal disorders among computer users, this study was aimed at investigating the prevalence of musculoskeletal disorders and awareness about the principles of ergonomics among computer users.
Method: In this descriptive-analytical and cross-sectional study, data were collected using demographic questionnaires, Nordic questionnaire, and self-constructed questionnaires. Chi-square, independent t-test, ANOVA, and correlation analyses were used to analyze the data statistically.
Results: The most prevalent signs of musculoskeletal disorders were in the waist, neck, shoulder, back, wrists, and knees. The level of awareness about the appropriate height of monitor and the proper distance between eyes of the operator and monitor was low. Although musculoskeletal disorders were lower in people with high levels of awareness about computer ergonomics, no significant relationship was found between the frequency of musculoskeletal disorders and awareness about computer ergonomics.
Conclusion: Awareness about computer ergonomics could impact on the prevalence of musculoskeletal disorders. So, informing computer users about knowledge of computer ergonomics and creating times to perform stretching exercises while working with computers are essential.
Key words: Musculoskeletal disorders knowledge of ergonomics, computer users, awareness
