Abstract: (82 Views)
Background: Proper ergonomics in the workplace is the key to preventing occupational injuries because following the principles of ergonomics reduces musculoskeletal disorders in computer users. For this reason, it is very important to know the effective factors in the computer work environment. Therefore, the purpose of this study was to determine the ergonomic status and musculoskeletal disorders of computer users in health centers of Mashhad City, Iran, and the related factors using a transtheoretical model.
Methods: A total number of 234 employees in health centers of Mashhad City participated in the present cross-sectional study from January to May 2023. For sampling, the five centers of Mashhad City were considered as strata, and people from all strata who met the entry criteria were included in the study. The data collection instruments included a demographic information questionnaire, a questionnaire on the transtheoretical model constructs, the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), and the Rapid Office Strain Assessment (ROSA) checklist. The data were analyzed in SPSS software.
Findings: The total ROSA score showed that 168 participants (71.8%) were at the warning level and 66 participants (28.2%) were at the level of necessity of intervention. The prevalence of musculoskeletal disorders in the neck (69.2%), lower and upper back (50.4% and 48.7%), and right shoulder (48.3%) was higher than other organs. In terms of being in the stages of change in the transtheoretical model, most people were in the contemplation stage and intended to change their behavior in the next 6 months. Results of multiple regression showed that gender (P = 0.020), education (P = 0.003), and hours of working with the computer (P = 0.041), along with the perceived barriers (P = 0.043), had the greatest impact on the ergonomic status of users.
Conclusion: As the results showed, computer workstations in health centers had a high level of risk. The present findings can be used to guide the development of interventions in working populations in organizations and offices.
