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