Three scores gauge physical and mental capacity in older men
In an observational study of 1,705 Australian men aged 70 or older, higher scores were linked to less dependency and lower mortality.
Limit: The overall capacity factor was not associated with the sensory domain

In an observational study of 1,705 Australian men aged 70 or older, researchers developed three measures of intrinsic capacity—the combination of a person’s physical and cognitive abilities. One used 21 commonly used indicators. Two used 10 indicators each, including one designed for clinical use with input from specialists in older people’s health.
All three models fit the data acceptably. Higher scores were associated with less dependence on help with daily tasks at the start and less new dependency over two years. Higher scores were also linked to lower mortality over 10 years. The clinically informed measure performed comparably to the more comprehensive, literature-based measure, supporting the authors’ approach of tailoring measurement to its intended use.
Why it matters
Consistent measures of physical and cognitive capacity could help researchers compare evidence on healthy aging across studies and settings.
Caveats
The measures were developed and evaluated using one cohort, leaving their performance in women, younger people and other populations uncertain. The study is a preprint and has not been peer-reviewed.
