Objective: The SARC-F is a five-question sarcopenia screening tool. The performance of the SARC-F may differ depend ing on the definition of sarcopenia. This study compared the performance detection of SARC-F for sarcopenia using four different criteria.
Methods: Measurement of physical function, body composition, and questionnaires, including the SARC-F, were per formed in 100 older adult users using a daycare facility. Sarcopenia was defined using the criteria of European Working Group on Sarcopenia in Older People (EWGSOP), the Asian Working Group for Sarcopenia (AWGS), International Working Group on Sarcopenia (IWGS), and Foundation for the National Institutes of Health (FNIH). The performances of the SARC-F for each sarcopenia were compared using the receiver operating characteristic curve (ROC) analysis, sensitivity, and specificity.
Results: The prevalence of each sarcopenia ranged from 15.0– 51.0%, depending on each definition method. The area under the curve ranged from 0.717– 0.792, with sensitivity and specificity ranging from 47.1–70.0% and 72.6–81.6%, respectively.
Conclusion: Although the performance of the SARC-F varies depending on the sarcopenia definition method, it performs consistently well in populations with low physical function, such as daycare and day rehabilitation users.
