Abstract

Background Sarcopenia is a multifactorial syndrome characterized by a decrease of muscle mass and force together with functional performance impairment. Sarcopenia has been described as an independent predictor factor of health adverse outcomes such as falls, decreased quality of life, enhanced risk of death and higher treatment costs. However, there are just a few screening tolls of low cost and easy applicability to detect sarcopenia. In this context, a standard mobility assessment such as the TUG test has recently been described as a predictor of sarcopenia.

Objectives To evaluate the performance of timed up and go test (TUG) as a screening toll for sarcopenia in the elderly.

Methods This is a cross-sectional home study with 211 elderly participants of the South Region of Brazil. Sarcopenia diagnosis criteria was based on the European Working Group on Sarcopenia in Older People (EWGSOP). Individuals that presented low muscle mass (women: ≤6.37kg/m2 and men: ≤8.90kg/m2) added to decreased handgrip strength (women: <20kgf and men: <30kgf) and/or walking speed (≤0.8m/s) were considered sarcopenic. TUG test quantifies functional mobility through the task of getting up from a chair, walking 3m and come back to sit on the chair.

Results Based on EGWSOP criteria for sarcopenia, 17.1% (n=36) received the sarcopenia diagnosis. A ROC curve was constructed to evaluate the discriminatory power of TUG (AUC: 0.73 [IC 0.67 – 0.78; p=0.0001]). TUG test presented high sensibility (88.9%) and negative predictive values (93.2%), with a cutoff point of 7.5 seconds (figure 1).

Conclusions Detecting the beginning of sarcopenia could allow for early interventions and slow the syndrome process, preventing further hospitalizations and economic burden. In this context, TUG is an easy, fast and low-cost test with high sensibility for sarcopenia detection that could be used as screening toll for this syndrome.
