Osteopenia is defined by which T-score range?

• A. Less than -2.5.
• B. Greater than -1.0.
• C. Between -2.0 and -1.0.
• D. Between -1.0 and -2.5.

Answer: (D)

A T-score shows how your bone density compares to a young healthy reference group, measured in standard deviations. Normal bone density is at -1.0 or higher. Osteopenia sits between that and osteoporosis, typically from -1.0 down to -2.5. Osteoporosis is defined as -2.5 or lower. So osteopenia corresponds to the range between -1.0 and -2.5, indicating lower density than normal but not yet in the osteoporosis range.
