What is ELSI-Brazil

Brazil is experiencing among the world’s fastest demographic aging worldwide. This demographic transition is occurring in a context of few resources and great social inequalities.

ELSI-Brazil (The Brazilian Longitudinal Study of Aging) 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-Brazil 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 9.412 individuals aged 50 years and older from 70 municipalities across the 5 great geographical regions. Follow-up waves are planned from time to time.

By adopting a similar methodology to other longitudinal ageing studies around the world, ELSI offers the opportunity for cross-national comparisons. Its findings will provide strategic scientific data that in turn has the potential to subsidized policies to promote healthy ageing and improve the quality of health services in later life.

A succinct description of the ELSI’s design was published in The American Journal of Epidemiology 1, in the year 2018.
