How many hallmarks of frailty are listed?

• A. 4
• B. 6
• C. 8
• D. 10

Answer: (B)

Frailty is described as a multi-domain syndrome, and the number of hallmarks depends on the framework being used. In the Fried frailty phenotype, five criteria are typically listed. The material used for this question, however, defines six hallmarks of frailty, adding an extra dimension beyond the five Fried criteria. That’s why six is the best choice here—the question is aligned with the six-hallmark framework specific to the source you’re studying. Knowing which framework your exam or course uses is key, since different models may use five, six, or other formulations.
