Background: The burden of occupational injury in most developing countries including Ethiopia is becoming a public health problem. Therefore, information that shows the magnitude and predictors of occupational injury in most risky work places in Ethiopia such as metal processing and working industries is indispensable to inform proper intervention programs to have healthy workforce and sound economic development. Objective: This study is intended to assess the magnitude and factors affecting occupational injuries among workers engaged in large scale metal manufacturing industries in Addis Ababa. Method: Institutional cross sectional study was conducted in Addis Ababa from February to March 2010. 50% of large scale metal manufacturing industries were selected by simple random sampling after stratification. Then, calculated sample size was allocated for each industry by PPS. And then, Study subjects were stratified by working sections and those who were directly engaged in the work were selected from each stratum by simple random sampling after preparing a frame from payroll of those industries. Structured questionnaire was designed to collect information on outcome variables and factors. Observational checklist and in-depth interview with key informants was held to triangulate the information with quantitative findings. Result: The overall prevalence of occupational injury was 489 per 1000 exposed workers per year. 119(29.4%) of injured workers were hospitalized or stayed at home bed with 98(82.4%) for 24 or more working hours and one death was reported in 12 months. Sex of workers [AOR:3.32, 95%CI: (1.88,5.85)],Safety and health supervision [AOR: 1.60,95%CI:(1.03,2.60)], Hours worked per week [AOR: 2.37,(95%CI:(1.55,3.61)], Cigarette smoking [AOR: 3.36,95%CI: (1.73,6.50) ] and presence of functional danger signs/ posts [AOR: 2.65,(95%CI: (1.67,4.19)] were significantly associated factors with magnitude of occupational injury. Conclusion and Recommendation: The burden of occupational injury in metal manufacturing industry is really significant public health problem. So continues health and safety information, basic occupational health services and additional cohort study for factors should be undertaken.
