To examine the prevalence and the agreement among different diagnosis criteria of pre-sarcopenia and sarcopenia in a population of COPD patients. All patients underwent a DXA body composition exam, and for physical capacity, patients underwent a six-minute walk test. We defined pre-sarcopenia and sarcopenia by four different criteria: Baumgartner, Newman, Mixed, and Foundation for the National Institutes of Health (FNIH).121 patients were studied. Pre-sarcopenia was observed in 19.8 to 46.3% depending on the criterion, higher with the FNIH criterion. The agreement among the criteria was poor. The positive percent agreements (%PPA) between the FNIH criterion and other criteria were low. However, the negative percent agreement (%NPA) was higher. The prevalence of sarcopenia was 4.9 to 12.4% depending on the criterion, also higher with the FNIH criterion. The agreement among the criteria was fair-to-good. The %PPA between the FNIH criterion and other criteria were higher than in pre-sarcopenia and also the %NPA was very high. In our study, the prevalence of pre-sarcopenia and sarcopenia was greater with the FNIH criterion. The agreement among the methods was better in sarcopenia than in pre-sarcopenia. We suggest that the FNIH criteria would be more suitable for this population of patients.
