Ethics approval and consent to participate

: Ethiopian Demographic and Health Survey obtained ethical clearance from Ethiopian Health Nutrition and Research Institute (EHNRI) Review Board, the National Research Ethics Review Committee (NRERC) at the Ministry of Science and Technology of Ethiopia, the Institutional Review Board (IRB) of ICF International, and the Centre for Disease Control (CDC). During the data collection, the interviewer read aloud a statement to get consent from the respondents. The respondents provided verbal consent, as Demographic and Health Survey is conducted in areas where not all respondents are able to write. The interviewers then signed their name to document that the statement was read and that consent was granted or declined. Children were not respondents to interview; however, parent/guardians gave consent for measurements.The authors have submitted proposal to the United Nations Population Fund (UNFPA) Ethiopia country representative and an ethical clearance granted by the Amhara National Regional State Health Bureau [Ethiopia] Ethics Committee for further analysis of the 2000, 2005 and 2011 Ethiopia Demographic and Health Surveys. The ethical approval reference number is HRTT 11/338107.
