Ethics approval and consent to participate
: The institutional review boards of the Harvard School of Public Health, Ifakara Health Institute, National Medical Research Coordinating Council of Tanzania and the WHO Ethical Review Committee approved the study protocol. Individual informed consent was sought from parents who provided written informed consent for their and their child’s participation in the study. The study IRBs determined that mothers 15–18 years of age were considered to be emancipated minors and therefore parents of mothers under 18 did not require consent from their parent/guardian for their or their child’s participation. Mothers under 15 years of age were excluded from the study.
