What are the five criteria used to define frailty according to the clinical syndrome described in the chapter?

The five criteria used to define frailty as a clinical syndrome are: unintentional weight loss of 10 pounds in the past year, self-reported exhaustion, weakness based on grip strength, slow walking speed, and low physical activity.

Frailty is identified as a clinical syndrome when an individual exhibits three or more of the following criteria: unintentional weight loss of 10 pounds within the past year, self-reported exhaustion, weakness as measured by grip strength, slow walking speed, and low physical activity levels. These criteria help in assessing the vulnerability of older adults to adverse health outcomes and guide healthcare providers in planning appropriate interventions and treatments.
