Question

Quizplus · Accepted Answer

DXA scanning compares an individual's BMD to that of persons with peak bone mass in their twenties, which is considered the reference value for optimal bone density. Comparing to similar persons in the same age group or with similar lifestyles and ethnicity may not accurately reflect the individual's bone health, and using BMD values from early childhood would not reflect current bone health status.
