Population ageing is a global phenomenon. Increases in life expectancy in Brazil, similarly to the observed in the rest of the world, are a result of improvements in socioeconomic, environmental, and technological conditions, as well as successful public health interventions. These improvements lead to new major challenges such as the promotion of active aging and the provision of health and social care for older adults who demand more of such needs.
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 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.
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 the Ministry of Health to develop public health policies to promote healthy ageing and improve the quality of health services in later life.
A succinct description of ELSI was published in The American Journal of Epidemiology 1, in the year 2018.
