背景：评估肌肉力量和肌肉质量与骨质疏松症(OP)的相关性具有特殊的意义，因为肌肉是干预(即力量训练)的潜在目标。方法：一项横断面描述性研究，涵盖天津汉沽地区60岁的人群(平均年龄：66.9±6.2岁；男性，516；女性，n=652)。研究人群被邀请参加一项全面的老年评估。OS是通过使用定量超声测量跟骨来识别的，T评分小于-2.5。肌肉特征包括握力和附件骨骼肌块(ASM)。结果：OS的患病率为61.6%，其中男性52.1%，女性69.1%。握力与OS呈负相关，在调整所有其他变量后，发现较高的握力与较低的OS风险相关(p=0.023)。ASM/身高(2)与OS无相关性(p=0.205)。结论：在老年人OS中，肌力而不是肌肉质量与OS呈负相关，因此在OS的早期阶段应更加重视肌力训练。版权所有(C)2017，台湾医学会。爱思唯尔台湾有限责任公司出版。
Background: Assessment of the association of muscle strength and muscle mass with osteoporosis (OP) is of special interest as muscles are a potential target for interventions (i.e., strength training).Methods: A cross-sectional descriptive study encompassing people aged >= 60 years (average age: 66.9 +/- 6.2 years; men, n = 516; women, n = 652) in the Hangu area of Tianjin, China. The study populations were invited to participate in a comprehensive geriatric assessment. OS was identified by measuring the calcaneal using a quantitative ultrasound and a T score of less than -2.5. Muscle characteristics included grip strength and appendicular skeletal muscle mass (ASM).Results: The prevalence of OS in this study was 61.6% (male 52.1%, female 69.1%). Grip strength was negatively related to OS and after adjusting for all other variables, higher grip strength was found to be associated with a lower OS risk (p = 0.023). ASM/height(2) was not associated with OS (p = 0.205).Conclusion: Based on our study, muscle strength rather than muscle mass is negatively associated with OS in older people; thus, we should pay more attention to muscle strength training in the early stage of the OS.
