The ELSI-BRASIL has been planned to survey about 10,000 Brazilians every three 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 took place in 2014 and the baseline data were collected in 2015-16 among 10,000 individuals aged 50 and over from 70 municipalities. Additional waves will take place every 3 years, and 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 are conducted by face to face.

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


Biomarker collection was performed at baseline and at each six-year follow-up when sample refreshment takes place.
