The ELSI-BRASIL has been planned to survey about 10,000 Brazilians every two years. The study will collect information about income, work, assets, pension plans, health plan, disability, physical health and functioning, cognitive functioning, and health care use and expenditures. The study is sponsored by the Brazilian Ministry of Health and the coordinator center is the Oswaldo Cruz Foundation in Minas Gerais, Brazil.


Data Collection
The ELSI-BRASIL is a longitudinal survey of a nationally representative sample of adults aged 50 and older. The pilot study was planned to be conducted in 2014 and the baseline data collection in 2015. New cohorts will be added every six years. The ELSI-BRASIL observational unit is an eligible household unit (uncoupled individuals and couples) that must include at least one age-eligible member. Interviews will be conducted by face to face. 

A wide variety of data are collected in ELSA, including demographic data (Income, employment, consumption, expectations), Health (Health behaviours, mental health, psychological and social well-being) and other measures of functioning (Social and civic participation, cognition).

Biomarkers

Biomarker collection will be performed at baseline and at each four-year follow-up.
