What are the 5 specific criteria in the Fried Frailty Phenotype used to diagnose frailty?

✓ Accepted answer

The Fried Frailty Phenotype diagnoses frailty when an individual meets three or more of five specific, measurable criteria: unintentional weight loss, self-reported exhaustion, low physical activity, slow walking speed, and weak grip strength. This standardized tool, originally developed by Dr. Linda Fried and colleagues in 2001, remains the gold standard for identifying physical vulnerability in older adults. Understanding these distinct markers helps families differentiate between normal aging and true physiological decline, which significantly impacts care planning and intervention strategies.

• Unintentional Weight Loss: A loss of 10 pounds (4.5 kg) or more in the past year, not due to intentional dieting or medical treatment.
• Self-Reported Exhaustion: The individual’s own perception of fatigue or lack of energy, often measured by validated survey questions.
• Low Physical Activity: Typically defined as expending less than the median caloric expenditure for their age and sex group, often measured using a leisure-time metabolic equivalent (MET) score.
• Slow Gait Speed: Walking speed below the median for their age, sex, and height group; clinicians often use a 4-meter or 15-foot timed walk test to assess this.
• Weak Grip Strength: Measured with a handheld dynamometer, falling below the median for the individual’s demographic profile.

While tools like the Frailty Index are also used in the UK and US, the Fried Phenotype specifically highlights physical dysfunction. If a senior exhibits two or more of these signs, they are often classified as "pre-frail," warranting early intervention through exercise and nutritional support. Contact a doctor or emergency services immediately if the individual experiences a sudden inability to stand up, falls twice or more in a year, or reports new-onset confusion alongside these physical symptoms.
