【摘要】：目的:参照两种肌肉衰减症国际共识,从肌肉质量、肌肉力量和身体活动能力等3个维度上对上海市老年女性肌肉衰减状况进行层层分析。方法:以上海市60~69岁之间的健康老年女性作为研究对象(E组),分别采用3D人体形态测量法、生物电阻抗法(BIA)、双能X射线吸收法(DEXA)以RASM和SMI这两项国际通用指标对肌肉质量进行考量;采用握力计、Contrex等动训练器对受试者上、下肢肌肉力量进行测评;采用10 m步速、FRT、TUG、Berg平衡量表、SPPB测试等进行身体活动能力评定,最后分别参照两种国际共识就肌肉衰减症的检出率进行初步判定。结果:1)无论是采用BIA法,还是DEXA法测量,E组SMI值均随增龄呈现显著下降(P0.001),而RASM值未见显著变化(P0.05);2)E组握力、相对握力、下肢各关节伸肌和屈肌的各项力学指标也均随增龄显著下降(P0.001),且相对握力同下肢肌力多数指标间相关性较为显著;3)E组步速、FRT、BBS得分、SPPB得分等均随增龄显著下降(P0.05),并伴有TUG耗时显著上升(P0.05),其中,SPPB测试不仅同握力和相对握力间呈现显著正相关,而且同TUG和BBS测试也具有显著相关性(P0.05);4)两种共识标准下,采用RASM指标时肌肉衰减症检出率均较低,仅介于0%~3.5%,而采用SMI指标时相应检出率均为12.3%。结论:步入60岁以后,老年女性在3个维度均呈现显著下降;当参照两种共识进行肌肉衰减症判定时,SMI指标较RASM指标的检出效果更为稳定;建议今后将RASM和SMI两指标综合考量,并将相对握力和SPPB分别作为肌肉力量维度和身体活动能力维度的首选指标。总之,早日建立中国共识将有助于今后运动干预研究的开展。
[Abstract]:Objective: to refer to the international consensus on two kinds of muscle attenuation, from muscle mass, Three dimensions of muscle strength and physical activity were used to analyze the muscle attenuation of elderly women in Shanghai. Methods: the healthy elderly women aged between 6069 years old in Shanghai were chosen as the subjects of study group E, and 3D was used respectively. Human body shape measurement, The muscle quality was evaluated by RASM and SMI, and the muscle strength of lower limbs was measured by the grip force meter and Contrex etc. The physical activity ability was evaluated by 10 m step FRTT TUG Berg balance scale and SPPB. Finally, the detection rate of muscle attenuation was preliminarily determined according to two kinds of international consensus. Results: 1) BIA method was used. The SMI values of group E were significantly decreased with age by DEXA method, but the value of RASM did not change significantly in group P0.05 and 2E, and the relative grip strength was not significantly changed. The mechanical indexes of extensor and flexor of lower extremities were significantly decreased with age, and the correlation between relative grip strength and most indexes of lower extremity muscle strength was significant. The scores of FRTBBS and SPPB in group E were significantly decreased with age (P 0.05). The time taken by TUG was significantly increased (P 0.05), and not only was it positively correlated with grip strength and relative grip strength, but also there was a significant positive correlation between SPPB test and relative grip strength. There was also a significant correlation with TUG and BBS tests (P0.05 / 4). Under two common standards, the detection rate of muscle attenuation was lower when RASM was used, which was only between 0 and 3.5, while the corresponding detection rate of SMI was 12.30.Conclusion: after 60 years of age, the detection rate of muscle attenuation is lower than that of RASM. The elderly women showed a significant decrease in all three dimensions, and when judging muscle attenuation with reference to two kinds of consensus, the detection effect of SMI was more stable than that of RASM. It was suggested that RASM and SMI should be considered comprehensively in the future. The relative grip strength and SPPB were regarded as the first choice indexes of muscle strength dimension and physical activity ability dimension respectively. In a word, the early establishment of Chinese consensus will be helpful to carry out the study of exercise intervention in the future.
