Definition of abbreviations: ASM = appendicular skeletal muscle mass; BMI = body mass index; EWGSOP2 = European Working Group on Sarcopenia in Older People 2; FNIH = Foundation for the National Institutes of Health; Lowest Quartile = distribution-based lowest quartile of sarcopenic study participants.
*
Limited definitions require only appendicular skeletal muscle mass below specified cut-point for diagnosis of sarcopenia.
†
Expanded definitions require both appendicular skeletal muscle mass and either grip strength or gait speed below specified cut-points for diagnosis of sarcopenia.
