【摘要】：目的:參照兩種肌肉衰減癥國際共識,從肌肉質量、肌肉力量和身體活動能力等3個維度上對上海市老年女性肌肉衰減狀況進行層層分析。方法:以上海市60~69歲之間的健康老年女性作為研究對象(E組),分別采用3D人體形態(tài)測量法、生物電阻抗法(BIA)、雙能X射線吸收法(DEXA)以RASM和SMI這兩項國際通用指標對肌肉質量進行考量;采用握力計、Contrex等動訓練器對受試者上、下肢肌肉力量進行測評;采用10 m步速、FRT、TUG、Berg平衡量表、SPPB測試等進行身體活動能力評定,最后分別參照兩種國際共識就肌肉衰減癥的檢出率進行初步判定。結果:1)無論是采用BIA法,還是DEXA法測量,E組SMI值均隨增齡呈現(xiàn)顯著下降(P0.001),而RASM值未見顯著變化(P0.05);2)E組握力、相對握力、下肢各關節(jié)伸肌和屈肌的各項力學指標也均隨增齡顯著下降(P0.001),且相對握力同下肢肌力多數(shù)指標間相關性較為顯著;3)E組步速、FRT、BBS得分、SPPB得分等均隨增齡顯著下降(P0.05),并伴有TUG耗時顯著上升(P0.05),其中,SPPB測試不僅同握力和相對握力間呈現(xiàn)顯著正相關,而且同TUG和BBS測試也具有顯著相關性(P0.05);4)兩種共識標準下,采用RASM指標時肌肉衰減癥檢出率均較低,僅介于0%~3.5%,而采用SMI指標時相應檢出率均為12.3%。結論:步入60歲以后,老年女性在3個維度均呈現(xiàn)顯著下降;當參照兩種共識進行肌肉衰減癥判定時,SMI指標較RASM指標的檢出效果更為穩(wěn)定;建議今后將RASM和SMI兩指標綜合考量,并將相對握力和SPPB分別作為肌肉力量維度和身體活動能力維度的首選指標�？傊�,早日建立中國共識將有助于今后運動干預研究的開展。
[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.
