Differences in bone quality and strength between Asian and Caucasian young men.

摘要: This is a cross-sectional study to assess differences in bone quality young Asian and Caucasian (n = 30/group) men between 25 35 years. We found that Asians had smaller bones, thicker denser cortices, more plate-like trabeculae, but stiffness did not differ groups. conducted measured mineral density (BMD) at the spine, total hip (TH), femoral neck (FN), forearm by dual energy X-ray absorptiometry (DXA), geometry, density, microarchitecture, mechanical competence radius tibia high-resolution peripheral quantitative computed tomography (HR-pQCT) with application of individual trabecula segmentation (ITS) trabecular whole finite element analysis (FEA). load-to-strength ratio account for size height, respectively. used Wilcoxon rank sum generalized linear models adjusted weight, their interaction comparisons. were 3.9 % shorter weighed 6.5 % less than Caucasians. In models: DXA, there no significant race-based areal BMD; HR-pQCT, radius, area (p = 0.003 both), (p = 0.01) (p = 0.04) cortices radius; ITS, Asians, rod-like trabeculae (PR p = 0.01), greater plate surface (p = 0.009) longer rod length (p = 0.002). There FEA or ratio. biomechanical estimates strength Studies are needed determine whether these persist later life.
