Background: Injury is one of the factors that contribute to health problems and disabilities. In Indonesia, the data oninjury and its impact are still limited and only focus on formal workers. Methods: This research aimed to describe thecharacteristics of injury by occupation and to identify factors contributed to severity (length of stay in hospital) amongproductive age workers in Indonesia, using the data of National Health Research (Riskesdas) in 2013. Results: We analyzed30.455 data using complex samples at 95% confi dence level. People worked as farmer, fi sherman, labor, entrepreneur,and others had more injuries in 12 months than employee (p = 0.0001). Non traffi c accident as cause of injury was alsohigher in those group of occupations than employee (p = 0.0001). The contributing factors of length of stay in hospital werethe injury with concussion (OR 23.1; 95% CI 9.2–58.1 p = 0.0001), fractures (OR 6.3; 95%CI 4.6–8.6 p = 0.0001), eyeinjury (OR 3.0; 95% CI 1.2–7.3 p = 0.0001), followed by road traffi c accident (OR 2.1; 95% CI 1.5–2.9 p = 0.0001), andinjury occurred in the business/industry/construction/farm area (OR 1.7; 95% CI 1.2–2.4 p = 0.006). Conclusion: Factorsthat contributed to the length of stay in hospital of the injury were the type of injury, cause of injury, and the area of injury.Recommendation: Efforts to overcome the injury need to be improved, especially for traffi c accidents and injury in thebusiness/industry/construction/farm area.
