Validating intrinsic capacity to measure healthy aging in an upper middle-income country: Findings from the ELSI-Brazil.

ABSTRACT:

Background

While efforts have been made to validate intrinsic capacity (IC) as a multidimensional indicator of healthy aging in high-income countries, we still need evidence from lower-income countries. We examined associations of IC with wide ranges of activities of daily living in a nationally representative sample of Brazilians aged≥50 years.

Methods

This cross-sectional analysis included 7175 participants from the Brazilian Longitudinal Study of Aging.
