Trabecular bone score in obese, overweight and normal-weight young men

Abstract

Objective: The aim of this study was to compare Trabecular Bone Score (TBS) in obese, overweight, and normal-weight young men. Methods: This study included 12 obese, 32 overweight, and 23 normal-weight young Lebanese men. Weight and height were measured, and body mass index (BMI) was calculated. Body composition, bone mineral content (BMC), bone mineral density (BMD), and lumbar spine (L1-L4) TBS were assessed by dual-energy X-ray asborptiometry (DXA). Physical activity, daily calcium intake and Pittsburgh sleep quality index were evaluated using validated questionnaires. Maximal oxygen consumption (VO2 max in l/min) was measured whilst exercising on a bicycle ergometer using a specialized device. Results: Weight, lean mass, fat mass, BMI, whole body (WB) BMC and WB BMD were significantly different among the three groups (obese, overweight and normal-weight). Trabecular Bone score (TBS) was not significantly different among the three groups (obese, overweight and normal-weight). In the whole population (n = 67), weight, lean mass, BMI and VO2 max (l/min) were positively correlated to BMC and BMD but not to TBS. Conclusion: This study suggests that obesity and overweight do not positively affect trabecular bone score values in young men. Body mass index is not a determinant of trabecular bone score in young men.
