Ethics approval and consent to participate
: The Institutional Review Board of Federal MOH, Sudan (FMOH/DGP/RD/TC/2016; January 15, 2017) and the Korea Association of Health Promotion (130750–20,164-HR-020; May 16, 2016) approved this study. Informed consent was obtained from head teachers and students. Participation in this survey was confidential and entirely voluntary. Withdrawal with no adverse consequences was possible at any time without having to give a reason. If a student agreed to take part, he or she was invited to participate in an interview and requested to provide stool and urine samples. Informed consent was obtained from the head teachers of all schools in a written format. A separate informed consent form for students was developed, the script was read by data collectors, and every detail was explained to students point by point. If a student decided to participate in the study, his or her name was documented to record verbal consent. It was impractical to obtain written consent from the parents of schoolchildren due to the large sample size, and we obtained approval for this procedure from the Institutional Review Board of Federal Ministry of Health, Sudan. The survey protocol for informed consent complied with the standard procedure of Federal Ministry of Health, Sudan.
