摘要
目的：探讨骨密度与体成分、下肢肌力、抗骨折能力、之间的相互关系。方法：选定40-89岁进行健康查体的妇女626名，测定身高、体重、计算体重指数，采用骨密度仪测量股骨颈骨密度，神经关节功能测试仪测定下肢肌力、抗骨折能力、全身的脂肪含量，进行各观察指标间的相关性分析。结果：股骨颈骨密度与身高、体重、体重指数和全身脂肪含量、下肢肌力均成显著正相关；与股骨颈抗骨折能力呈正相关；股骨颈抗骨折能力与骨密度、下肢肌力成正相关，与体重及体重指数、全身脂肪含量呈负相关。结论：重体重、脂肪含量高的人有较高的骨密度，但其抗骨折能力并不一定强。中年以后体重增加而下肢肌力及骨密度下降是造成机体抗骨折能力下降的重要因素。抗骨折能力做为诊断骨质疏松的一个新的指标在临床诊断及治疗中不可忽视。
Objective： To investigate the relationship among bone mineral density, muscle strength of lower limbs, bone strength, and body components.Method： 626 health women aged 40 - 80were measured by duel energy X- ray absorptiometry and the Mobility Evaluation System.Result： Bone mineral density had significant positive correlation with Bone weight , BMI , body fat mass and muscle strength of lower limbs; Bone strength had significant positive correlation with muscle strength of lower limbs and bone mineral density . Bone strength had significant negative correlation with weight, BMI and body fat mass. Conclusions： People with heavy weight have higher bone mineral density but not higher bone strength.With increasing of weight and descending of streght of lower limbs and bone mineral dens/ty after middleaged, bone strength become lower. Bone strength should not be neglected in clinical diagnosis and treatment.
