Ethics approval and consent to participate
: For the original conduct of the 2014–15 Chad Demographic and Health Survey (DHS), ethical approval was obtained from the ethical committee of the ICF. The enumerators obtained informed consent and authorisation to anonymously use the data from all survey participants. In our study, we obtained permission to use the data from the DHS program. No further ethical approval was required, as our study solely involved secondary data analysis of publicly available data that does not contain any identifiable information that links to the actual survey participants.
