Abstract: Objective To explore the feasibility of using the consensus of European Working Group on Sarcopenia in Older People(EWGSOP) to diagnose sarcopenia among community-dwelling women aged from seventy to seventy-nine in Shanghai.Methods Twenty-two healthy community-dwelling women were recruited as the subject group(group S),and another ten young girls were randomly selected as the control group(group C).The anthropometry,bioelectrical impedance analysis(BIA)and dual energy X-ray absorptionmetry(DEXA)were used to evaluate the circumferences of upper and lower limbs,and the dimension of muscle mass,according to relative appendicular skeletal mass(RASM)and skeletal muscle index(SMI).The grip dynamometer and isokinetic dynamometer were used to measure the muscle strength of upper and lower limbs.The ten meters gait speed,functional reach test,timed up and go test,Berg balance scale and short physical performance battery were all applied to assess the physical performance.The criteria of EWGSOP consensus were applied to diagnose the situation of sarcopenia.Results Firstly,the average biceps circumference and fat mass of upper limbs in group S were significantly higher than group C (P＜0.01),while no significant differences were observed in the muscle mass(P＞0.05).Secondly,RASM values gained from BIA and DEXA in S group were significantly higher than C group(P＜0.05),while the SMI values of the former were significantly lower than the latter(P＜ 0.01).Thirdly,absolute grip strength,relative grip strength and other bio-mechanical indexes of lower limbs in the s group were significantly lower than the C group(P＜0.01);the relative grip strength showed significant correlation with most bio-mechanical indexes of lower limbs.Fourthly,the physical performance in group S declined significantly compared with that of the c group(P＜O.05),and no significant correlation was found between muscle strength and physical performance of upper limbs except the absolute grip strength and gait speed.The prevalence was 0％ according to the RASM index,while the prevalence was 63.6％ and 45.4％ according to the BIA and DEXA respectively.Conclusion The assessing pattern from EWGSOP consensus could not be simply copied to applying on Chinese old people due to serious difference between RASM and SMI.The combination of "SMI+relative grip strength+ TUG/SPPB/Berg" may be better than the classical mode of "RASM+absolute grip strength+gait speed" in diagnosing sarcopenia.
