Abstract
Abstract Objective: to evaluate the performance of the Timed Up and Go test (TUG) as a screening tool for sarcopenia in elderly persons living in a city in the south of Brazil. Method: A cross-sectional, home-based study was conducted with 322 elderly persons. The diagnosis of sarcopenia was based on the criteria proposed by the European Working Group on Sarcopenia in Older People (EGWSOP). A Receiver Operating Characteristic (ROC) curve was constructed to assess the discriminatory power of the TUG on sarcopenia screening. Results: With a cutoff point of 7.5 seconds, the test had an area under the curve (AUC) of 0.66 (CI 0.56-0.76; p=0.002) and adequate sensitivity and negative predictive values (88.9% and 93.2%, respectively). Conclusion: Due to its ease of use and rapid execution, in addition to its low cost, this test is useful for the screening of sarcopenia, especially among elderly persons with good physical and cognitive abilities. The early identification of individuals with probable sarcopenia may allow for preventive or directive interventions for the management of this geriatric syndrome.
