BACKGROUND
Low bone mass is an independent risk factor for osteoporotic fractures. We examined the association between physical performance and bone mass using quantitative ultrasound in community-dwelling postmenopausal Japanese women.
METHODS
We conducted a cross-sectional study on 524 community-dwelling postmenopausal Japanese women who were not being administered osteoporosis medications. Physical performance was assessed on the basis of grip strength, chair stand time, and functional reach. The stiffness index was measured as a quantitative ultrasound parameter for heel bone mass.
RESULTS
Physical performance, assessed by grip strength, chair stand time, and functional reach, and the stiffness index significantly decreased with age (both p<0.001). The multiple linear regression analysis showed that grip strength (p = 0.001), chair stand time (p = 0.004), and functional reach (p = 0.048) were significantly associated with the stiffness index after adjusting for age, body mass index, smoking, drinking, and exercise.
CONCLUSIONS
Physical performance was significantly associated with heel bone mass in community-dwelling postmenopausal Japanese women.
背景
低骨量是骨质疏松性骨折的独立危险因素。我们使用定量超声检查了 524 名居住在社区的绝经后日本女性的身体表现和骨量之间的关系，这些女性没有服用骨质疏松症药物。
方法
我们对 524 名居住在社区的绝经后日本女性进行了一项横断面研究，这些女性没有服用骨质疏松症药物。身体表现是基于握力、椅子站立时间和功能伸展来评估的。硬度指数是作为脚跟骨量的定量超声参数进行测量的。
结果
握力、椅子站立时间和功能伸展的身体表现以及硬度指数随年龄增长显著下降（均 P<0.001）。多线性回归分析表明，在调整年龄、体重指数、吸烟、饮酒和运动后，握力（P=0.001）、椅子站立时间（P=0.004）和功能伸展（P=0.048）与硬度指数显著相关。
结论
在居住在社区的绝经后日本女性中，身体表现与脚跟骨量显著相关。
