RESUMO
Introduction: The lack of agreement between job demands and worker capacity and repetitive / restless working may lead to cumulative trauma disorders. These disorders occur during months and years of facing with extra-physical and psychological stressor in work environment. This study was conducted among workers of an aluminum industry in Hormozgan to determine the prevalence of CTDs and MSDs. The result of this study can be used to develop CTD preventive strategies in the workplace towards improving workers health
Methods: In this descriptive cross-sectional study 200 workers from 6 production units of the factory were studied by Nordic musculoskeletal questionnaires [NMQ] and the prevalence of CTDs and MSDs was measured. Data analysis was performed by Spss 15 software and chisquare test
Results: The highest percentage of neck and waist CTDs was found in crane drivers and the highest percentage of wrist/hand and shoulders CTDs respectively were found in welding and Anode production workers. A Significant relationship was found between the CTDs at waist and height and age, weight and work history at 0.05 significance level. In addition, work history and age showed a significant relationship with wrist/hand CTDs
Conclusion: The high prevalence of CTDs in this study with regarding to this point that majority of the studied workers had a short work history indicated that attention to this problem is necessary. Therefore application of control measures to eliminate or reduce exposure of employee to the ergonomics stressors associated with the development of CTD is recommended
