| Summary: | Osteoporosis is a common bone disease in older adults, and it is a predictor of
bone fracture. This study determined the mean trabecular bone score (TBS) of
older Taiwanese men in different age groups and analyzed the effectiveness of TBS
in predicting osteoporosis risk. A total of 1568 men aged 50 and older were
enrolled. The demographic characteristics; bone mineral density (BMD) T-scores of
the spine, total hip, and femoral neck; and TBS of the spine were recorded to
statistically determine osteoporosis-related factors. The average age (range) of
the included patients was 59.5 ± 7.5 (50.0–92.7) years. The mean (range)
TBS was 1.386 ± 0.073 (0.999–1.605). The TBS was moderately and positively
correlated with the BMD T-scores of the spine, total hip, and femoral neck (r =
0.516, 0.499, and 0.480, respectively). The lowest of the BMD T-scores measured
at multiple sites revealed a higher rate of osteoporosis (5.5%) than did BMD
T-scores measured at individual sites. Moreover, bone microarchitecture
degradation was noted in 2.2% of the patients. Compared with the use of BMD
alone, a combination of BMD and TBS predicted more patients (1.4%) to be at a
high risk of osteoporosis. Combining the lowest BMD and TBS revealed that 20.3%
of patients aged ≥70 years had a high risk of osteoporosis. TBS can be
used to clinically assess the risk of osteoporosis in older adults without
osteoporosis. We recommend combining the lowest BMD T-score and TBS for
predicting the risk of osteoporosis.
