Ethical approval and consent to participate

: The technical proposal of this study was presented to the ethical review committee of Jimma University. After review and approval (including the use of verbal consent) by the committee, permission to proceed with the study was obtained from ESR health bureau and administrative bodies of the Karamara hospital. Informed verbal consent of subjects to participate in the study was secured before conducting the interview. This was done with a page of consent letter attached to the cover of the questionnaire which stated the general purpose of the study, the need and benefits of conducting the study, and issues of confidentiality. The interviewers briefly discussed the contents of the consent letter before proceeding to the interview. Confidentiality was kept at each step of data collection and processing. The participants were assured that they have full right to participate or withdraw from the study at any time they want to.
