Ethics approval and consent to participate
: The study protocol was approved by the ethical review committee of the College of Medicine and Health Sciences, University of Gondar. Besides, we took ethical approval from Amhara Public Health Institute. Verbal informed consent was taken from all respondents enrolled in the study and this was approved by the Institutional review board (IRB). Written informed consent was not taken since several participants were unable to read and write and the study involves no more than minimal risk. Also, for children between 13 and 18 years, permission was obtained from the farm leaders and assent was obtained from children themselves based on a child’s level of comprehension. In this case for children between 13 and 18 years the IRB gave a waiver. To keep confidentiality, respondent’s names and other personal identifiers were not included. The collected data were password protected.
