What is the formula used to calculate a T-score?

Explanation:
The formula for calculating a T-score is essential for assessing bone density in comparison to a young adult reference population. The T-score gives a clear understanding of how an individual's bone mineral density (BMD) relates to the average BMD of a healthy young adult. The correct formulation involves subtracting the young adult mean BMD from the individual's measured BMD and then dividing by the standard deviation (SD) of the young adult population. This method effectively shows how many standard deviations the individual's BMD is above or below the young adult mean, allowing for a standardized comparison. For instance, if an individual's BMD is significantly lower than the young adult mean, the resulting T-score would be negative, indicating decreased bone density and potential risk for conditions like osteoporosis. Conversely, a positive T-score would indicate a higher BMD compared to the reference population. This method is crucial in clinical settings as it helps healthcare providers assess and communicate the risk of fracture and other related issues more effectively.
