Sarcopenia according to the European Working Group on Sarcopenia in Older People (EWGSOP) versus dynapenia as a risk factor for mortality in the elderly

BACKGROUNDSarcopenia and dynapenia have been associated with poorer physical performance, disability and death. The aim of this study was to compare the association between sarcopenia and dynapenia with mortality. METHODSWe studied 1,149 Brazilians aged 60 years or older residing in São Paulo. Sarcopenia was defined according to the consensus of the European Working Group on Sarcopenia in Older People (EWGSOP), which includes three components: low muscle mass (LMM) assessed by skeletal muscle mass index ≤ 8.90kg/m2 (men) and ≤ 6.37kg/m2 (women); low muscle strength (LMS) assessed by handgrip strength
