Physical performance as a predictor of mortality in nursing home residents: A five-year survival analysis

Abstract

This study developed a five-year survival analysis to verify the relationship between the Short Physical Performance Battery (SPPB) and death in older adults residing in nursing homes (NHs). A total of 114 residents of NHs in Northeast Brazil participated in the follow-up. In addition to the SPPB, the older adults answered questions about sociodemographic and health condition information. The relationship between physical performance and mortality was evaluated using the Kaplan Meier survival curves and Cox proportional regression. As a result, 61.40% of the participants presented low performance and 41.22% died. Low physical performance increased the chance of death by 2.77 times in five years (adjusted Hazard Ratio 2.77; 95% CI 1.40-5.50; p < 0.01). Low SPPB Gait Speed Test also represented a 2.58-fold increased risk of dying (adjusted HR 2.58; 95% CI 1.38-4.83; p < 0.01). The results of this study showed that low physical performance can predict the mortality of older adults residing in NHs over five years.
