Fried Frailty Phenotype (CHS)

Classifies older adults as robust, pre-frail, or frail from the five Fried Cardiovascular Health Study criteria (weight loss, exhaustion, grip weakness, slow gait, low activity). Screening tool with sex- and body-size-specific cutoffs; not a substitute for comprehensive geriatric assessment.
