Key summary pointsAimTo evaluate the impact of (1) different adjustments of body size, (2) regional grip strength thresholds, and (3) EWGSOP1 and EWGSOP2 algorithm on sarcopenia prevalence using regional muscle mass thresholds in a geriatric outpatient clinic specific to endocrinological problems.FindingsThere was no sarcopenic patient with the height square adjusted regional muscle mass thresholds for EWGSOP1 and EWGSOP2. Sarcopenia prevalence was 11.7% with EWGSOP2, and 41.1% by the use of regional grip strength thresholds for EWGSOP2 with body mass index adjustments.MessageThe prevalence of sarcopenia varied significantly regarding the adjustment method for muscle mass in this specific patient group including normal to overweight and obese individuals, and also the regional grip strength thresholds whereas the comparison of the two criteria was not possible due to lack of sarcopenic individuals with height square adjusted regional muscle mass thresholds. AbstractPurposeThe aim of this study was to determine the prevalence of sarcopenia according to different methods in older outpatients using regional threshold values of muscle mass and muscle strength.MethodsWe used data from our university hospital's geriatric outpatient clinic specific to endocrinological problems, retrospectively. Sarcopenia was defined according to European Working Group on Sarcopenia in Older People (EWGSOP)1 and EWGSOP2 criteria using regional threshold values of skeletal muscle mass (SMM) with the use of different adjustments, and also according to EWGSOP2 with regional threshold values of grip strength.ResultsAmong 248 study participants, 53.6% were obese. There was no sarcopenic patient with the height square adjusted regional SMM thresholds for EWGSOP1 and EWGSOP2. Sarcopenia prevalence was 11.7% with EWGSOP2, and 41.1% by the use of regional grip strength thresholds for EWGSOP2 with body mass index adjustments for SMM. The comparison of EWGSOP1 versus EWGSOP2 was not possible due to lack of sarcopenic patients with height adjustment.ConclusionsThe prevalence of sarcopenia varied significantly with the application of different adjustment methods for SMM, and the use of regional grip strength thresholds in the specific patient group with normal to overweight and obese individuals. The use of regional thresholds of grip strength increased the prevalence of EWGSOP2-defined sarcopenia. The impact of the adjustment methods, the characteristics of the study population, and the regional thresholds should be taken into consideration while evaluating the results of sarcopenia studies.
