Occupational diseases are consequences of various workplace hazards. Cumulative trauma disorder or repetitive strain injury indicates the effect of repeated physical movements and partial pressure on muscles, tendons and other soft tissues of body. This is the most common disease caused by work. Materials and Methods: This descriptive cross-sectional study performed on state office workers in Kerman city in 2007. Data was collected using examination and three questionnaires about work-related diseases, job satisfaction and job stress. After completion of the questionnaires, a trained researcher analyzed the collected data by SPSS 13 and Chi square test. A level of P≤0.05 was considered significant. Results: Data analysis showed that factors such as repeated writing, typing, using computers at work, repeated lifting objects at the table level, traffic through the steps, traffic through the office corridor, reach of foot to the ground when sitting on the chair, using footrests under desk, using chair cushions, using lumber pillows, or swivel chair were not the cause of cumulative trauma disorder. Repetitive bending and refusal to lean against the seat when sitting were effective in causing the disease. Other findings of our research were employees’ ergonomic awareness status, job satisfaction and job stress being calculated according to the median scores for all three factors as average. Conclusion: Repetitive bending and avoidance from leaning against the chair were significant factors causing high rates of cumulative trauma disorder in office workers of Kerman city. Modification of these factors or even using lumbar supportive equipment may reduce the high prevalence of this disease. Cumulative trauma disorder was found less in employees under the age of thirty and the rates increased with age and work history, linearly.
