AIM: The aim of this study was to investigate the association between fall and performance in the “chair stand” test; and evaluate this test as a predictor of community-dwelling Brazilian elderly men fallers.MATERIAL AND METHODS: This was a study based on secondary data derived from a population-based epidemiological study involving 143 elderly men. The association between fall and performance in the “chair stand” test was tested with the Poisson regression technique (robust model adjusted by age). The discriminatory power of the “chair stand” test was determined by the ROC curve. In all analyses the level of significance adopted was 5% (α = 0.05). The data were analyzed in the IBM SPSS and MedCalc. The participants’ age ranged from 60 to 105 years (73.4 ± 9.4 years). The time for performing the test ranged from 6 s to 31 s (13.2 ± 5.0 s) and 17.7% (n = 25) reported having suffered at least one fall in the last 12 months.RESULTS: The Poisson multiple regression model (adjusted by age) showed that the spent time to perform the “chair stand” test was positively associated (PR = 1.08; CI95% = 1.02 - 1.14; P = 0.009) with the occurrence of fall in the last 12 months. The power of the “chair stand” test to discriminating the elderly who suffered fall may be visualized by means of the ROC curve parameters. The value of AUC indicates that the “chair stand” test was able to discriminate individuals who suffered and those who did not suffered fall. The cut-off point of 12 s was the one that best discriminated the occurrence of fall, presenting sensitivity = 68.4% and specificity = 60.0%.CONCLUSIONS: The results indicated that the “chair stand” test was associated with fall and presented predictive potential for elderly men fallers
