Notes: Quantitative variables are expressed as mean ± standard deviation, qualitative variables are expressed as count (percentage). aBody Mass Index. bEstimated Skeletal Muscle Index by bio impedance analysis (BIA). cRapid Assessment of Physical Activity questionnaire. dAt least one fall (traumatic or not) within the last 12 months. eDiagnosis was possible for 76 participants regarding EWGSOP2 algorithm; diagnosis was not possible when BIA was dysfunctional (n=15), and for participants with both BMI >31 and low physical performance (n=9).
Abbreviations: NS, no sarcopenia; PS, probable sarcopenia; S, sarcopenia; SS, severe sarcopenia.
