Background: Musculoskeletal disorders are among the most important work-related diseases and hard working conditions in workshops and industries lead workers to experience these disorders. This study aimed to examine the prevalence of musculoskeletal disorders and its relationship with work ability index, job satisfaction, and job burnout among the workers of Isfahan Crystal and Glass Industry, Isfahan, Iran. Methods: This descriptive-analytic study was a cross-sectional one employing 251 workers from Isfahan Crystal and Glass Industry and was conducted in 2021. The data were collected through Cronell Musculoskeletal Disorders Questionnaire (CDMQ), Work Ability Index Questionnaire (WIA), Job Descriptive Index (JDI), and Copenhagen Burnout Inventory (CBI). The collected data were then submitted to SPSS to be analyzed through descriptive and inferential (Spearman correlation) statistics. The significance level was decided to be less than 0.05 (P < 0.05). Findings: 45.4% of the participants had musculoskeletal discomfort in at least one limb and 63.7% had high level of job satisfaction. On the other hand, the participants had high level of job burnout (mean = 81.55) and intermediate level of work ability (mean = 36). Further, there were no significant correlations between musculoskeletal disorders and job burnout, and between musculoskeletal disorders and work ability (P < 0.050), whereas there was a significant correlation between musculoskeletal disorders and job satisfaction (P < 0.050). Conclusion: Less than half of the participants had musculoskeletal disorders. The significant relationship between musculoskeletal disorders and job satisfaction was negative; the higher the level of job satisfaction, the lower the level of musculoskeletal disorders. Moreover, interventional and corrective measures are highly recommended to prevent these disorders.
