: Institutional review board (IRB) approval was obtained from the Johns Hopkins Bloomberg School of Public Health as well as from the ethics committee in each state. The State ethics committees that granted approval for data collection were University of Uyo Teaching Hospital Institutional Health Ethics Committee for Akwa Ibom State, Kebbi State Health Research Ethics Committee for Kebbi State and Dalhatu Araf Specialist Hospital Health Research Ethics Committee for Nasarawa State. In addition, interactions with the respondents followed standard ethical procedures. Informed consent was obtained from all study participants prior to the interview. Fieldworkers explained to study participants that participation was voluntary, that they could refuse to participate or answer any questions, and that they could terminate the interview at any time. Furthermore, participants’ confidentiality was protected through face-to-face interviews in the absence of a third party, by not retaining any personally identifiable information in the electronic data set, limiting access to a paper-based listing of households to only the research staff, and destroying the listing immediately after data collection was completed in the relevant cluster. All protocols were carried out in accordance with relevant guidelines and regulations.
