摘　　要：目的探讨上海地区部分老年人骨密度与骨骼肌肌量、力量和功能的相关性研究。方法选取2020年7-12月于上海市徐汇区漕河泾街道社区卫生服务中心招募的513例老年患者作为研究对象。采用双能X线骨密度仪(DXA)测量研究对象骨密度,并测量步速、握力、身高、体质量,计算体重指数、四肢骨骼肌指数,比较不同性别老年患者临床资料,Pearson相关性分析骨密度与骨骼肌肌量、力量和功能的关系。结果男性老年人握力、身高、体质量、四肢骨骼肌指数、全身骨密度均高于女性老年人,差异有统计学意义(P<0.05)。Pearson相关性分析结果显示,全身骨密度与四肢骨骼肌指数、握力均呈正相关(r>0,P<0.05)。结论上海老年人骨密度与四肢骨骼肌指数、握力密切相关,且应重视肌肉减少症与骨质疏松症的综合性防治,减少肌少-骨质疏松症引起的各种负担和风险。Objective To investigate the correlation between bone mineral density and muscle mass,skeletal muscle mass and strength and func-tion in some elderly people in Shanghai.Methods 513 elderly patients recruited from Caohejing Street Community Health Service Center in Xuhui District of Shanghai from July to December 2020 were selected as the research subjects.The whole body bone mineral density of the subjects was measured by dual-emission X-ray absorptiometry(DXA),and the walking speed,grip strength,height and body weight,body mass index and limb skeletal muscle index were calculated.The clinical data of elderly patients with different genders were compared,Pearson correlation analysis was used to analyze the relationship between bone mineral density and skeletal muscle mass,strength and function.Results The grip strength,height,body weight,limb skeletal muscle index and whole body bone mineral density of male elderly people were higher than those of female elderly peo-ple,and the differences were statistically significant(P<0.05).Pearson correlation analysis showed that whole body bone mineral density was posi-tively correlated with limb skeletal muscle index and grip strength(r>0,P<0.05).Conclusion The bone mineral density of the elderly in Shang-hai is closely related to the skeletal muscle index and grip strength of the limbs,and attention should be paid to the comprehensive prevention and treatment of sarcopenia and osteoporosis to reduce the various burdens and risks caused by sarcopenia-osteoporosis.
