Diagnostic Criteria for Sarcopenia by Organization.
| Organization | Diagnostic criteria |
|---|---|
| EWGSOP, version 2 | Low muscle strength (grip strength <27 kg in males and <16 in females) Low skeletal muscle mass (in terms of appendicular skeletal mass per height; <7.0 kg/m2 in males or <5.5 kg/m2 in females) (2 standard deviations below the reference range of 8.8 kg/m2 for males and 6.84 kg/m2 for females) For the diagnosis of severe sarcopenia, low muscle performance (gait speed of ≤0.8 m/s or SPPB of ≤8) |
| ESPEN-SIG | Low skeletal muscle mass (in terms of appendicular skeletal mass per height; <7.26/m2 in males and <5.5 kg/m2 in females (2 standard deviations below reference range of 8.6 kg/m2 for males and 7.3 kg/m2 for females) and one of the following: Low skeletal muscle strength (grip strength <30 kg in males and <20 kg in females) Low muscle performance (gait speed <0.8–1.0 m/s) |
| IWGS | Low skeletal muscle mass (in terms of appendicular skeletal muscle mass per height; 7.23 kg/m2 in males and 5.67 kg/m2 in females) (lowest 20% of distribution for each sex) Low muscle performance (gait speed <1 m/s) |
| FNIH | Low muscle strength (grip strength <26 kg in males and <16 kg in females) Low muscle mass (in terms of appendicular lean mass per BMI; <0.789 in males and <0.512 kg in females) (established by regression analysis) |
| AWGS | Low skeletal muscle mass (in terms of appendicular skeletal mass per height; <7.0 kg/m2 in males or 5.4 kg/m2 in females by DEXA or 5.7 kg/m2 by BIA) and one of the following: Low muscle strength (grip strength <28 kg for males and <18 for females) or Low muscle performance (gait speed <1 m/s or SPPB ≤9) |
| International Conference on Frailty and Sarcopenia Research | Per EWGSOP, FNIH, IWGS, or AWGS diagnostic criteria |
