Declarations

:

: This study has been submitted to the Addis Ababa University College of Health Sciences Institutional Review Board (IRB) for ethical review. The study has granted Ethical approval from the Institutional Review Board with Protocol number: 057/16/SPH. An official letter from Addis Ababa University School of Public Health was sent to factories to participate in the study. Prior to the study the research team visited the factory and discussed with the factory management and agreed on voluntary participation in the study. Access to the factory’s human resource and disease diagnosis data was granted by the factory’s management. We generated a unique identification number for each worker without the worker’s name in the database during analysis and reporting to protect privacy. A dissemination workshop was organized and the finding of the study was presented to factory management and workers’ representatives.
