Prevalence of Occupational injury and associated factors among workers in Harar Brewery Factory, Harar, Eastern Ethiopia

Abstract

Abstract Background: Occupational accidents and work-related diseases cause over 2.3 million deaths annually; nearly 860,000 people are injured every day globally. However, there are No studies that specifically determine the magnitude and associated factors of occupational injury in Brewery workers in Ethiopia. Objective: The aim of this study was to assess the prevalence and associated factors of occupational injury among workers in Harar Brewery Factory, Harar, Eastern Ethiopia. Methods: An institution based cross-sectional study design was implemented from March 18 to April 20, 2018 among 410workers who were selected by stratified samplingtechniquein each department and draw sample from each department proportionally by computer generating technique. Amharic version questionnaires were used to collect the data with face to face interview using trained six data collectors and two supervisors. Data was entered into Epi Info version 7 and exported to SPSS Version 20 software for data cleaning and further analysis.Binary logistic regression model for bivariate and multivariable analyses were applied to explore the relation between the dependent and independent variables using crude and adjusted odds ratio with 95% CI, respectively. Finally, to determine the factors associated with occupational injury after controlling confounders. Variables with P-value <0.05 in the final model were considered statistically significant. Results: The annual prevalence of occupational injury was 19.5% with 95%CI (15.9, 23.1). Abrasion was the common injury and hand figures were the most affected body parts.Employment type being temporarily [AOR 10.893,95%CI: (3.800, 31.226)], work environment related factors like extra working hours [AOR 5.319 95%CI: (1.994, 14.190)], among the behavioral factors, job stress [AOR 8.56295%CI: (2.632, 27.855), Personal Protective Equipment use[AOR0.109 95%C.I:(0.038, 0.312)] anddrinking alcohol [AOR 6.72195%C.I:(3.357, 13.458)] were statistically significant factors to determine occupational injuries among Brewery workers. Conclusion: The magnitude of occupational injury in brewery workers was relatively low in study area. Temporarily employment, extra working hours, job stress, status of PPE use and alcohol use were the identified predictors for occupational injury in brewery workers.Occupational injury among brewery workers may not be ignorable health problem. There for, monitoring and control strategy could be recommended to prevent occupational injury among brewery workers.
