What does a lower T-score typically indicate?

• A. A higher risk of fractures
• B. A stronger bone structure
• C. An athlete’s optimal performance
• D. An increase in bone density

Answer: (A)

A lower T-score is an important indicator in bone densitometry, as it reflects the density of an individual's bones in comparison to the bone density of a healthy young adult. Specifically, a T-score of -1 or higher is considered normal, while a T-score between -1 and -2.5 indicates osteopenia (low bone mass), and a T-score of -2.5 or lower indicates osteoporosis. When the T-score is lower, it signifies reduced bone density, which correlates with a higher risk of fractures. The correlation between lower T-scores and increased fracture risk is well-established; individuals with osteoporosis (indicated by lower T-scores) suffer from weakened bone structures that are more susceptible to breaks under stress or trauma.

In contrast, options highlighting stronger bone structure, optimal athletic performance, or increases in bone density would not align with the implications of a lower T-score. These conditions typically correspond to higher T-scores, reflecting better bone health and density. Therefore, a lower T-score is directly linked to increased fracture risk due to the deterioration of bone quality, making the first response the most appropriate choice.
