Frailty among the elderly is a result of the complex interplay between social and clinical factors involved in its genesis. However, it is still unclear whether the fraailty syndrome can be aggravated due to lack of social support. The scope of this study was to analyze the association between social support and the frailty syndrome among elderly residents in the community. It is an analytical observational cross-sectional study, with a sample of 300 elderly people. Socio-demographic, economic and physical health, frailty and social support data were collected. For statistical analysis, the Pearson chi-square, the Student t and the binary logistic regression were performed, adopting a significance level of 5%. No associations were observed between frailty and the social support variables, except for the housekeeping aspect (p = 0.04). In logistic regression frailty with age (OR = 1.19), physical activity (OR = 2.56) and self-perceived health (OR = 3.33) remained associated. It is considered that more studies need to be conducted to characterize social vulnerability and health services also need to recognize the importance of social support as an integral part of care for the elderly.

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 (65-74 years-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 (R(2) = 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)., (© 2012 Japan Geriatrics Society.)
