摘要
目的:探究中老年人肌肉、脂肪(FM)与骨密度(BMD)之间的联系。方法:随机招募了年龄范围54~81周岁的277名受试者,男性137人,女性140人。采用相对四肢骨骼肌含量(RASM)方法定义骨骼肌减少症,其年轻成年人平均值和标准差参照中国香港学者发布的数据。结果:控制年龄的影响,四肢骨骼肌含量(ALM)以及相对四肢骨骼肌含量(RASM)与男、女性身体各个区域的BMD显著正相关,脂肪与女性全身、股骨颈BMD显著正相关。在多元模型中,ALM是影响BMD的重要影响因素。结论:对于中老年人,骨骼肌含量与骨密度有紧密正向联系,女性脂肪含量与骨密度有正向联系,建议有必要进一步研究骨骼肌含量与脂肪含量是否独立影响骨密度。
Objective: To access the association of muscle and fat with bone mineral density (BMD)of middle-aged and older people. Methods: 277 Chinese adults ( 137 men and 140 women) aged 54-81 were randomly recruited. Sarcopenia were calculated using RASM diagnostic criteria, while Hong Kong researches' data was as the reference of the value of mean and standard deviation of the young people. Results: After adjustment for age, appendieular skeletal muscle mass(ALM) and relative ap- pendieular skeletal muscle mass(RASM) were positively associated with BMD of every area in both men and women. FM were positively associated with BMD of whole body and femoral neck area in women. In a multivariable model, ALM was most consistently associated with BMD. Conclusion: For middle-aged and older people, ALM was strongly associated with BMD. Fat mass was associated with BMD. Further studies are necessary to determine whether muscle mass and fat mass dependently influence the BMD.
