This study aimed to investigate the predictive role of grip strength on bone mineral density (BMD) of different sites in males. Two hundred thirty-four male patients were included in the study. BMD of lumbar spine, femoral neck, proximal radius-ulna (PRU) and distal radius-ulna (DRU) sites were measured by dual-energy X-ray absorptiometry and grip strength by using a hand dynamometer. Grip strength and BMD values of PRU and DRU at forearms were significantly higher on the dominant sides (P = 0.001, P = 0.001, P = 0.001, respectively). Stepwise linear regression analysis revealed that only the grip strength of the same side was the best predictor of the BMD of the dominant and non-dominant PRU with a ratio of 8.5 and 10.2%, respectively, whereas grip strength of the same side, age and weight were the best predictors of the BMD of the dominant and non-dominant DRU with a ratio of 25 and 24.6%, respectively. There was no predictive value of grip strength for BMD of lumbar spine and femoral neck. In conclusion, grip strength appears to be predictive of site specific rather than systemic BMD.
本研究旨在探讨握力对男性不同部位骨密度（BMD）的预测作用。234例男性患者纳入本研究。采用双能X线吸收法测量腰椎、股骨颈、尺桡骨近端（PRU）和尺桡骨远端（DRU）部位的骨密度，使用握力计测量握力。优势侧前臂PRU和DRU的握力及骨密度值显著更高（分别为P = 0.001、P = 0.001、P = 0.001）。逐步线性回归分析显示，仅同侧握力是优势侧和非优势侧PRU骨密度的最佳预测指标，分别占比8.5%和10.2%，而同侧握力、年龄和体重是优势侧和非优势侧DRU骨密度的最佳预测指标，分别占比25%和24.6%。握力对腰椎和股骨颈骨密度无预测价值。总之，握力似乎是特定部位骨密度而非全身骨密度的预测指标。
