Notes
Women’s T-scores are based on NHANES 2005–2008 White women’s reference data
Men’s T-scores are based on NHANES 2005–2008 White men’s reference data
Men’s T-scores are based on NHANES 2005–2008 White women’s reference data
The total prevalence of osteoporosis is assessed when the T-score in any of the femoral neck or lumbar spine is ≤−2.5. Low bone mass is assessed when at least one of these two T-scores is >−2.5 and <−1.0.
