Osteopenia is defined as a T-score between which values?

• A. It is defined as a T-score between -1.0 and -2.5.
• B. It is defined as a T-score of -2.5 or lower.
• C. It indicates normal bone density.
• D. It indicates severe osteoporosis.

Answer: (A)

Understanding how T-scores categorize bone density is key. A T-score shows how many standard deviations a person’s bone mineral density is from a healthy young adult reference value. This helps distinguish normal density, osteopenia, and osteoporosis. Osteopenia occurs when the T-score falls between -1.0 and -2.5. A T-score above -1.0 is considered normal density. A T-score of -2.5 or lower indicates osteoporosis, and if there is a fragility fracture with that level of density, it’s termed severe osteoporosis.
