A T-score of -1 indicates which category?

• A. Osteoporosis
• B. Normal BMD
• C. Severe osteoporosis
• D. Osteopenia

Answer: (D)

A T-score tells how your bone mineral density compares to a healthy young adult of the same sex. It reflects how many standard deviations your density is from that young-mean. The thresholds used in many clinical schemes categorize density as normal (around 0 to -1), low bone mass or osteopenia (roughly -1 to -2.5), and osteoporosis (-2.5 or lower). So a T-score of -1.0 sits at the boundary and is considered osteopenia in this framework, indicating bone density below the normal young-adult mean but not low enough to be osteoporosis. This reflects a higher fracture risk than normal density, guiding preventive measures and risk-factor management.
