Differences in sarcopenia prevalence between upper-body and lower-body based EWGSOP2 muscle strength criteria: the Tromsø study 2015–2016

Table 3 Proportions of men and women crossing the sarcopenic threshold for each separate EWGSOP2 parameter

EWGSOP2 parameter	Men (n = 1451)	Women (n = 2047)	P
Grip strength	19 (1.31)	29 (1.42)	0.783
Chair stands	52 (3.58)	147 (7.18)	< 0.001
ALM_height²	86 (5.93)	90 (4.40)	0.038
Walk speed^{a, b}	74 (5.10)	150 (7.33)	0.006
TUG^{a, c}	1 (0.07)	7 (0.34)	0.129

Numbers are n (%). P-values are age-adjusted by logistic regression. ^aWalk speed and TUG had missing data for n = 2 and n = 3 participants respectively. ^bEWGSOP2 thresholds for walkspeed is ≤ 0.8 m/s. ^c EWGSOP2 thresholds for TUG is ≥ 20 s. ALM_height² = Appendicular Lean Mass relative to squared body height, TUG = Timed-Up-and-GO test. The Tromsø Study 2015–16
