ABSTRACT AIM OF THE STUDY : The aim of this study was to compare geometric indices of hip bone strength in overweight and control elderly men. METHODS & RESULTS : This study included 16 over- weight (Body mass index (BMI) > 25 kg/m2) elderly men (aged 65-84 years) and 38 age-matched controls (BMI < 25 kg/m2). Body composition and bone miner- al density (BMD) were assessed by dual-energy X-ray absorptiometry (DXA). To evaluate hip bone geome- try, DXA scans were analyzed at the femoral neck, the intertrochanteric region, and the femoral shaft by the Hip Structure Analysis (HSA) program. Cross sec- tional area (CSA), an index of axial compression strength, section modulus (Z), an index of bending strength, cross sectional moment of inertia (CSMI), an index of structural rigidity, cortical thickness (CT) and buckling ratio (BR) were measured from bone mass profiles. Lean mass, body weight, fat mass and BMI were higher in overweight men compared to con- trols (p < 0.001). CSA and Z were higher in overweight subjects compared to controls (p < 0.05) at the three regions (femoral neck, intertrochanteric and femoral shaft). After adjustment for age, CSA and Z of the in- tertrochanteric region and the femoral shaft remained significantly higher in overweight men compared to controls (p < 0.05). After adjustment for either body weight, BMI or lean mass, there were no differences between the two groups (overweight and controls) regarding the HSA variables (CSA, CSMI, Z, CT and BR) of the three regions. CONCLUSION : This study suggests that overweight elderly men have greater indices of bone axial and bending strength in comparison to controls at the intertrochanteric and the femoral shaft. RESUME OBJECTIF DE LÉTUDE : Le but de cette étude est de comparer les indices géométriques de résis- tance osseuse au niveau de la hanche chez des hommes âgés en surcharge pondérale et normo-pondérés. MÉTHODES & RÉSULTATS : 54 hommes âgés de 65 à 84 ans divisés en deux groupes en.
