[en] INTRODUCTION: In the definition of the European Working Group on Sarcopenia in Older People (EWGSOP), different cut-off limits are proposed for appendicular lean mass, muscle strength and gait speed. Therefore we aimed to examine the variation in prevalence of sarcopenia obtained with these cut-off limits. MATERIALS AND METHODS: Subjects aged 65 years and older were recruited in an outpatient clinic in Belgium and screened for sarcopenia using the EWGSOP definition. Appendicular lean mass was measured by Dual Energy X-Ray Absorptiometry, muscle strength by a hydraulic handgrip dynamometer and gait speed was measured on a 4-meter distance. Two different cut-off points proposed by the EWGSOP were examined for each variable and 8 diagnostic methods were thereby established. RESULTS: 400 subjects were recruited for this study. Prevalence of sarcopenia varied from 9.25% to 18% depending on the cut-offs applied. When stratified by sex, it seems that the variation in prevalence of sarcopenia was mainly attributable to women. This prevalence ranged from 6.58% to 20.2% for women and only from 13.4% to 14.7% for men. CONCLUSION: Prevalence of sarcopenia varies widely depending on the EWGSOP cut-off points applied for women. This may limit clinical researches and development of therapeutic strategies in the field of sarcopenia.
