Assessment of magnitude of occupational injuries and associated factors among micro-enterprise metal workshop workers in Addis Abeba,Ethiopia.

Background: Injuries in small scale enterprises are becoming a public health problem in developing countries including Ethiopia. The prevailing injuries could be prevented if appropriate measures are taken. In developing countries including Ethiopia, the risk of having work related injury is 10 to 20 times higher than that of developed countries. Objective: This study investigated the magnitude and associated factors of occupational injuries among microenterprise metal workshop workers in Addis Ababa. Methods: work-site based cross sectional study was employed among 540 micro metal workshop workers in Addis Ababa. Thirty (30%) of the Sub cities with the highest number of labor force were selected and sample size was allocated for each sub city based on proportional probability sampling. Firms were selected by simple random sampling. Trained data collectors administered a standardized questionnaire through face- to-face interview to collect information regarding participants practice, work-related and socio-demographic factors and outcome variable. Observational checklist was used to ascertain the information with quantitative findings. Data were checked for its completeness and coded and entered into Epi Info version 7.2.1.0. Data were analyzed using SPSS version 22 where descriptive and logistics regressions were computed to see association between different factors and work related injuries. Results: The overall annual prevalence rate of work related injury was 53.5% (95% CI: 49.4%, 57.7%). The significant contributing factors for work related injuries in metal workshops were work experience with five year or less (AOR: 4.85, 95% CI: 2.68, 8.79), working without shift (AOR: 8.93, 95% CI: 3.81, 20.97), work dissatisfaction (AOR: 3.25, 95% CI: 1.86, 5.66), alcohol drinking (AOR: 7.05, 95% CI: 4.07, 12.22) and not using PPEs (AOR: 2.94, 95% CI: 1.46, 5.91). Conclusion: Occupational injuries were found to be high. Lack of work experience, educational status, taking excessive alcohol, lack of work shift, health and ...
