FRAX provides 10-year fracture risk percentages for major fractures and hip.

• A. FRAX measures bone density directly.
• B. FRAX assesses vitamin D status.
• C. FRAX estimates height.
• D. FRAX provides 10-year fracture risk percentages for major fractures and hip.

Answer: (D)

FRAX is a fracture risk assessment tool that estimates the chance of fractures over the next 10 years. It uses clinical risk factors—such as age, sex, prior fracture, smoking, glucocorticoid use, rheumatoid arthritis, secondary osteoporosis, alcohol intake—and can include bone mineral density at the femoral neck if available to refine the estimate. The result is a percentage chance for two outcomes: a major osteoporotic fracture and a hip fracture within 10 years. It does not directly measure bone density, assess vitamin D status, or estimate height as a standalone output. Height and weight may be input to help calculate BMI and influence risk, but FRAX itself provides the fracture risk percentages, which is why this option is correct.
