Ethics approval and consent to participate
: The DHS project obtained the required ethical approvals from the National Health Research Ethic Committee (NHREC) in Nigeria before the surveys were conducted (Assigned Number NHREC/01/01/2007). Participants were informed of the rationale for the surveys, confidentiality of their responses, and that they don’t have to answer the questions if they do not feel comfortable doing so. Participants provided written informed consent before they were allowed to participate in the surveys. The data used in this study were anonymous and are publicly available to apply for online. Approval was sought from MEASURE DHS/ICF International and permission was granted for this use.
