What is considered osteoporosis in terms of T-score?

1. -1.5 or lower

2. -2.5 or lower

3. -2 or lower

4. -3 or lower

The correct answer is: -2.5 or lower

Osteoporosis is a medical condition wherein the bones become weak and brittle, making them more prone to fracture. The T-score is a measurement used to assess the density of a person's bones compared to the average peak bone mass in healthy young adults. A T-score of -2.5 or lower is considered to be indicative of osteoporosis. This means that a person's bone density is significantly lower than the average and puts them at a higher risk for fractures. While T-scores of -1.5 or -2 can indicate lower than normal bone density, they are not low enough to be classified as osteoporosis. A T-score of -3 or lower is considered to be severe osteoporosis. Therefore, -2.5 is the correct threshold for diagnosing osteoporosis in terms of T-score.
