title: Prevalence of sarcopenia in patients attending outpatient geriatric clinics: the ELLI study.
abstract: OBJECTIVE
  the aim of this study is to know the prevalence of sarcopenia in geriatric outpatient clinics using the EGWSOP (European Working Group on Sarcopenia in Older People) diagnostic criteria that include muscle mass, muscle strength and physical performance.
  
  
  METHODS
  subjects over 69 years old, able to walk without help and who attended five geriatric outpatient clinics were recruited. Body composition was assessed using bioimpedance analysis (BIA), grip strength using a JAMAR dynamometer and physical performance by the 4 m gait speed. Sarcopenia was diagnosed using the EGWSOP criteria (gait speed <0.8 m/s; grip strength <30 kg in men or <20 kg in women, and muscle mass index (MMI) <8.31 kg/m(2) in men or <6.68 kg/m(2) in women).
  
  
  RESULTS
  two hundred and ninety-eight subjects were included (median age 83.2 years, 63.1% women). 19.1% had sarcopenia (12.7% men, 22.9% women); 20.1% had low muscle mass; 68.8% had low gait speed and 81.2% low grip strength. Only 21.9% of the subjects with low grip strength and 19.5% of those with low gait speed had sarcopenia. No correlations between muscle mass and either muscle strength or gait speed were detected.
  
  
  CONCLUSIONS
  sarcopenia is present in one out of five subjects attending geriatric outpatient clinics.
