Question

Quizplus · Accepted Answer

BMD (bone mineral density) reporting in premenopausal females or males younger than 50 should be done in Z-scores rather than T-scores because T-scores are based on comparisons with young adult populations while Z-scores are based on comparisons with age-matched populations. This is because bone density typically peaks in early adulthood and declines with age, so comparing to a young adult reference population may inaccurately categorize individuals as having osteoporosis or low bone mass when they are actually within the expected range for their age.
