The Brazilian Longitudinal Study of Aging

ELSI-Brazil (The Brazilian Longitudinal Study of Aging or Estudo Longitudinal da Saúde e Bem-Estar dos Idosos Brasileiros) is a longitudinal, home-based survey, conducted in a nationally representative sample of older adults. The research aims to examine the social and biological determinants of aging and its consequences for the individual and for the society. ELSI is coordinated by the Oswaldo Cruz Foundation – Minas Gerais (FIOCRUZ-MG) and the Federal University of Minas Gerais (UFMG). The baseline survey was funded by the Brazilian Ministry of Health and the Ministry of Science, Technology, Innovation and Communication. The baseline data collection, performed in 2015-16, was conducted with a sample of about 10,000 individuals aged 50 years and older from 70 municipalities across different geographical regions. Follow-up waves are planned from time to time.
