Aim: To analyze the Short Physical Performance Battery's (SPPB) ability in screening for frailty in community-dwelling young elderly from cities with distinct socioeconomic conditions. Methods: Elderly (6574years-of-age) from Canada (Saint Bruno; n=60) and Brazil (Santa Cruz; n=64) were evaluated with the SPPB to assess physical performance. Frailty was defined as the presence of 3 of the following criteria: weight loss, exhaustion, weakness, mobility limitation and low physical activity. Linear regression and receiver operating characteristics analyses were carried out. Results: The SPPB correlated with frailty (R2=0.33), with better results for Saint Bruno. A cut-off of 9 in the SPPB had good sensitivity (92%) and specificity (80%) in discriminating frail from non-frail in Saint Bruno (area under the curve [AUC]=0.81), but showed fair results in Santa Cruz (AUC=0.61, sensitivity=81% and specificity=52%). Conclusions: The SPPB better discriminated frailty in elderly with higher socioeconomic conditions (Saint Bruno). Geriatr Gerontol Int 2013; 13: 421428.
