Declarations
:
: The information was collected as part of the Northern Nicaragua Health and Demographic Surveillance (NN-HDSS) update survey in 2014. All procedures during the design, fieldwork, data management, and analysis of the NN-HDSS –and for the present study– were guided following the ethical principles of the Declaration of Helsinki concerning epidemiological research involving human subjects. The Ethical Review Board of Biomedical Research at the National Autonomous University of León approved the NN-HDSS data collection (León 06 April, 2011. FWA00004523/IRB0000334 ACTA No. 81). Informed consent was obtained from participants and parents or caregivers from participants under 18 years of age. They were free to end their participation at any time. Data were stored in a safe electronic platform with an alphanumeric identification number instead of names of participants to protect confidentiality.
