关于肌肉力量是否与骨矿物质密度（BMD）独立于肌肉质量相关，有相互矛盾的报道。在这里，我们研究了肌肉力量和BMD之间的关系，在一个代表性的日本妇女人口。对680名绝经后妇女的横断面数据进行了分析，这些妇女是日本基于人群的骨质疏松症队列研究的第15年随访调查的参与者。采用双能X线骨密度仪测量股骨颈和腰椎的骨密度（aBMD）、全身骨密度和外骨骼肌质量（ASM，kg）。ASM指数（ASMI，kg/m2）的计算方法为ASM除以身高的平方（m2）。测量握力（kg）作为肌肉力量的指标。握力差异有统计学意义（P
There are conflicting reports on whether muscle strength is associated with bone mineral density (BMD) independently of muscle mass. Here, we examined the association between muscle strength and BMD in a representative population of Japanese women. Cross-sectional data from 680 postmenopausal women, who were participants in the 15th-year follow-up survey of the Japanese Population-based Osteoporosis cohort study, were analyzed. Areal BMD (aBMD) at the femoral neck and lumbar spine, whole-body bone mineral density, and appendicular skeletal muscle mass (ASM, kg) were measured by dual-energy X-ray absorptiometry. The ASM index (ASMI, kg/m(2)) was calculated as ASM divided by height squared (m(2)). Grip strength (kg) was measured as an indicator of muscle strength. Grip strength showed significantly (P
