Which of the following is NOT one of Fried's frailty criteria?

• A. Unintentional weight loss
• B. Weak grip strength
• C. High BMI
• D. Self-reported exhaustion

Answer: (C)

Fried's frailty phenotype identifies frailty by five physical criteria that reflect diminished physiologic reserve: unintentional weight loss, weakness (low grip strength), self-reported exhaustion, slow walking speed, and low physical activity. These criteria focus on loss of muscle mass and energy rather than body mass index. High BMI is not part of Fried's criteria, so it doesn’t fit as a frailty criterion. You can have a high BMI and still meet the frailty criteria if there’s unintentional weight loss, reduced grip strength, and fatigue, but BMI itself isn’t used to define frailty in this model. The other options listed are indeed components of Fried’s criteria.
