The Correlations of Lumbar Spine Trabecular Bone Score with Bone Mineral Density and Body Composition in Postmenopausal Women
It is well known that postmenopausal women are more predisposed to osteopenia and osteoporosis due to estrogen deficiency. Although bone mineral density (BMD) measured by dual energy x-ray absorptiometry (DXA) is a major determinant of bone strength, many other factors contribute to the risk of fractures. Trabecular Bone Score (TBS) is a novel method to estimate the trabecular microarchitecture using the lumbar spine DXA image, which can potentially evaluate bone health at an earlier stage (Silva et al. 2014). PURPOSE: To examine the relationships between the lumbar spine TBS with BMD and body composition in postmenopausal women. METHODS: Twenty-three female participants aged 50 to 77 years old completed the study (Age 59.4 ± 7.4 years old; Height 163.6 ± 6.1 cm; Weight 71.6 ± 11.9 kg). Total body composition and BMD at the lumbar spine and dual proximal femur were measured by DXA. Osteopenia (-2.5 < BMD T-score ≤ -1) and osteoporosis (BMD T-score ≤ -2.5) were classified according to the WHO criteria. Pearson’s correlation coefficient was used to explore the relationships between TBS, BMD and body composition variables. RESULTS: The prevalence of osteopenia and osteoporosis of this group of participants was 47.82% (11 out of 23 participants). The significant correlations were reported in Table 1. No significant correlations were found between TBS and age, height, and weight. CONCLUSION: Our results suggest that the lumbar spine TBS moderately correlates with lumbar spine BMD, total hip BMD and lean mass in postmenopausal women.
