Abstract
Introduction: Little is known about the normative values of trabecular bone score (TBS) in Thailand. We aimed to provide reference values of dual-energy x-ray absorptiometry (DXA)-derived lumbar spine TBS in Thai community-dwelling adults of varying ages. Methodology: Bone density studies of participants aged 20–90 years who underwent bone mineral density (BMD) testing at Srinagarind Hospital, Kohn Kaen, Thailand were reviewed. DXA studies were performed using a narrow fan-beam bone densitometer. Lumbar spine TBS for each of the L1–L4 vertebra was obtained using the iNsight software. Mean TBS (L1–L4 TBS) was calculated. This study was approved by the institutional research ethics committee (HE581241). Results: A total of 1372 participants were included. The mean ± SD age was 57.25 ± 17.35 years and 799 (58.2%) were female. There were 476 (34.7%) and 243 (17.7%) participants with osteopenia (T-score -1.0 to -2.5) and osteoporosis (T-score ≤-2.5) of the lumbar spine. Age and sex stratified analysis of L1–L4 TBS revealed peak TBS among females aged 30–49 years (mean ± SD: 1.42 ± 0.08) and males aged 30–59 years (mean ± SD: 1.42 ± 0.09). The rate of L1–L4 TBS reduction from ages 30 to 90 year is 13.4% (0.27%/year) for females and 5.6% (0.11%/year) for males. Conclusion: This is the first study reporting a normative database for DXA derived TBS in Thai community-dwelling population. We found that TBS decreased with age at the rate of approximately 0.27%/year for females and 0.11%/year for males.
