RESUMEN
Background: The Short Physical Performance Battery (SPPB) is an instrument for assessing physical performance widely used in research among the elderly in multiple settings. We did not find Brazilian longitudinal studies that aimed to analyze the predictive capacity and accuracy of the SPPB among community-dwelling older adults and no systematic reviews were found on the accuracy of the SPPB in predicting mortality in community- dwelling older adults. This study aimed to analyze the capacity and accuracy of the SPPB for predicting mortality in community-dwelling older adults, as well as to determine cut-off points for men and women. Method: Longitudinal observational study conducted with 411 (70.1 ± 7.25 years) community-dwelling older adults, between 2017 and 2020 (37.7 ± 6.24 months). Physical performance was evaluated using the SPPB and information on the all-cause mortality rate was also recorded. Multivariate Cox regression analyses and curves were performed using the Kaplan-Meier method. Receiver Operating Characteristic (ROC) curves were constructed, with the parameters of area under the ROC curve (AUC) to determine cutoff points for discriminating mortality, considering a significance level of 5% (p < 0.05) and 95% confidence interval (CI) 95%. Results: Older adults with very low and low physical performance in the SPPB, showed higher risks of mortality (HR = 9.67; 95% CI [1.20-77.65]; HR = 4.06; 95% CI [1.09-15.01]), respectively. In the subtest's analysis, older adults with low performance in the balance (HR = 0.54; 95% CI [0.36-0.81]) and gait speed tests (HR = 0.50; 95% CI [0.33-0.76]) showed greater risks of dying. The same was reproduced for categories in each test (participants that scored 2 points in the balance test had an HR = 5.86; 95% CI [1.84-18.61] and 2 points in the gait speed test, HR = 5.07; 95% CI [1.76-14.58]. The cutoff point ≤ 9 in the SPPB set the discriminator criterion for mortality in older people of both sexes. Conclusions: The SPPB, as well as the balance and gait speed subtests were predictors of mortality, and the SPPB is accurate in predicting mortality among community-dwelling older adults.

OBJECTIVE: To investigate the association of frailty syndrome with socioeconomic and health variables among older adults. METHODS: This is a cross-sectional, observational and analytical household research conducted with a sample of 1,609 urban elderly. We used: semi-structured questionnaire, scales (Katz, Lawton and shortened version of Geriatric Depression Scale) and Fragility Phenotype proposed by Fried. Descriptive analysis was performed along with a bivariate and multinomial logistic regression model (p <0.05). RESULTS: The prevalence of pre-frailty condition was 52.0% and the fragility corresponded to 13.6%. Pre-frailty and frailty associated factors were, respectively: age range between 70-79 years and ≥80 years; one to four morbidities and five or more morbidities categories; functional disability for basic and instrumental activities of daily life and depression indicative; whilst lack of a companion or income and female gender were only associated to pre-frailty. CONCLUSION: The conditions of pre-frailty and frailty levels were elevated with negative effects on the health of the elderly.
OBJETIVO: Investigar la asociación del síndrome de fragilidad con variables socioeconómicas y de salud de los adultos mayores. MÉTODOS: encuesta domiciliaria transversal, observacional y analítico realizado con una muestra de 1,609 personas mayores urbano. Fueron utilizados: cuestionario semi-estructurado, escalas (Katz, Lawton y depresión geriátrica acortado) y Fragilidad Fried fenotipo. Se realizaron los siguientes análisis: descriptivo, bivariado y modelo de regresión logística multinomial (p <0.05). RESULTADOS: La prevalencia de la condición pre-fragilidad fue del 52.0% y la fragilidad correspondió a 13.6%. Los factores asociados a la prefragilidad y fragilidad fueron, respectivamente: a los intervalos de edad de 70-79 años y ≥80 años; una a cuatro morbilidades y cinco o más categorías de morbilidad; incapacidad funcional para actividades básicas e instrumentales de la vida diaria y indicativo de depresión; en cuanto que la ausencia de compañero y ingreso y el género femenino se asociaron a la prefragilidad. CONCLUSIÓN: Las condiciones de los niveles previos a la fragilidad y la fragilidad fueron elevados con efectos negativos sobre la salud de los ancianos.
