Participants were recruited between January 2016 and March 2020 through household surveys and visits, where they completed structured questionnaires and underwent physical and biological assessments. Participants are followed up every 18 to 24 months through electronic questionnaires, household visits, and medical document collection to track both fatal and non-fatal health outcomes.
