Population ageing is a global phenomenon. The Brazilian population is undergoing one of the fastest ageing processes worldwide. Ageing has consequently become more important for social policy development. Increases in life expectancy in Brazil, similarly to the ones 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 other challenges such as the promotion of successful ageing and the provision of health care for older adults who will demand more use of health services/treatment.
ELSI-Brasil (The Brazilian Longitudinal Study of Ageing) is a longitudinal and nationally representative survey of older adults in Brazil that will start in 2015. ELSI-Brasil collects both objective and subjective data relating to health and funcniong, economic circumstances, social participation and networks, wellbeing and usage of health services. It aims to measure outcomes across a wide range of domains and to provide high-quality multidisciplinary data that can shed light on the causes and consequences of outcomes of interest.
The Brazilian Ministry of Health and the Ministry of Science and Technology, has funded ELSI-Brazil. The study is coordinated by the Rene Rachou Research Centre of the Oswaldo Cruz Foundation (FIOCRUZ), Minas Gerais State, Brazil. The sample size will comprise 10,000 participants aged 50 years and older from 7,500 households from 70 municipalities across different geographical regions.
The scientific findings from ELSI-Brasil will provide strategic information to help the Brazilian Ministry of Health to develop policies to promote successful ageing and to improve the quality of health care of older adults in Brazil.
