dc.description.abstractAIM: Sarcopenia is a common disorder of loss of muscle mass and function among older adults; however, few studies have examined screening instruments for sarcopenia risk in residential aged care services (RACS). The aims of this study were to measure sarcopenia risk in RACS residents using the SARC-F, describe factors associated with sarcopenia risk and examine the predictive validity of the SARC-F for 12-month mortality. METHODS: This was a prospective cohort study carried out in South Australian RACS across 12 sites. In total, 541 residents (mean age 87.7 [7.3] years, 72.6% women) were included in the study. Sarcopenia risk was measured using a modified SARC-F (≥4 point cut point). RESULTS: We identified 89.5% (n = 484) of residents at risk of sarcopenia. Significant (P > 0.05) predictors of sarcopenia risk in multivariable analysis included the presence of diabetes (relative risk [RR] = 1.08), classification as most-frail (RR = 1.06) and smaller Nursing Home Life Space Diameter (NHLSD) score (RR = 0.99). Mortality was observed in 20.9% (n = 113) of residents over a 12-month follow-up. Classification as at-risk of sarcopenia was a significant predictor of 12-month mortality; however, it had a poor area under the receiver operator curve (0.56), and a low positive predictive value (23.1%). The best performing cut-point of ≥7 also had poor discriminative ability (under the receiver operator curve = 0.66, positive predictive value = 30.8%). CONCLUSIONS: Sarcopenia risk is extremely common among RACS residents and its presence is a significant contributor to 12-month mortality. Low discriminative ability for the SARC-F was noted across multiple cut-off scores for predicting mortality at 12 months. Diabetes management and promoting physical activity and nutrition among RACS residents are likely to influence sarcopenia risk positively.
