Abstract:
Objective:To analyze the trabecular bone score (TBS) and its association with muscle health in the postmenopausal population.Methods:It was a cross-sectional study. A total of 214 postmenopausal individuals who underwent dual-energy X-ray absorptiometry testing at the Beijing Research Institute of Sports Science between January and December 2023 were consecutively included. The participants were divided into two groups based on the presence or absence of osteoporosis (OP): 62 cases in the OP group and 152 cases in the non-OP group. All subjects completed body composition assessments and scans of bilateral hip and lumbar spine bone mineral density (BMD)(All the BMD in this study were areal BMD). Demographic data, including age, age at menarche, age at menopause, and fracture history, were also collected. TBS was calculated using the TBS iNsight software. Muscle health indicators included upper limb, lower limb, trunk, and total muscle mass, lean body mass, appendicular skeletal muscle mass index (ASMI), and grip strength. The Pearson correlation analysis was used to determine the relationship between TBS and muscle health indicators, as well as between TBS and the BMD of lumbar spine (L 1-4). Further, multiple linear regression analysis was conducted to explore the independent association between TBS and muscle health indicators. Results:TBS, lean body mass, ASMI, grip strength, and muscle mass of the upper limb, lower limb, trunk, whole body in the OP group were all lower than those in the non-OP group [(1.27±0.07) vs (1.35±0.07) score, (36.64±3.45) vs (39.14±3.62) kg, (6.16±0.56) vs (6.44±0.63) kg/m2, (23.87±3.31) vs (25.34±4.33) kg, (3.54±0.47) vs (3.78±0.47) kg, (11.70±1.33) vs (12.68±1.49) kg, (16.57±1.68) vs (17.50±1.69) kg, and (34.91±3.33) vs (37.13±3.47) kg] (all P<0.05). Pearson analysis showed that TBS was positively correlated with lean body mass, ASMI, grip strength, and muscle mass of the upper limb, lower limb, whole body (all P<0.05). TBS was negatively correlated with age ( P<0.01). TBS was positively correlated with the BMD of lumbar spine (L 1-4) ( r=0.660, P<0.01). Multiple regression analysis demonstrated that ASMI was positively correlated with TBS ( β=0.284, P<0.01). Conclusion:In the postmenopausal population, individuals with OP have lower TBS. Furthermore, TBS is closely associated with muscle health.
