Fried frailty scale
This scale works as a scoring system that assigns one point for the
presence of each of the following 5 phenotypical manifestations that are
commonly found in frail individuals: shrinking (self-report of
unintentional weight loss of >4.5 kg in the past year),
self-reported exhaustion, weakness (measured with grip strength and
standardized by sex and body mass index), slow walking speed (measured
as time to walk 4.6 m. at usual pace and standardized by sex and
height), and low physical activity (using as cut-off value the
consumption of <383 Kcal per week for men and <270
Kcal per week for women). According to the total score obtained, the
individuals are classified as robust (0 points), pre-frail (1-2 points)
and frail (3-5 points).
