Objectives: To investigate the association between sarcopenia and chair stand test performance, and evaluate this test as a screening tool for sarcopenia in community-dwelling elderly women. Design: Cross-sectional Survey. Participants: 173 female individuals, aged >= 60 years and living in the urban area of the municipality of Lafaiete Coutinho, Bahia's inland, Brazil. Measurements: The association between sarcopenia (defined by muscle mass, strength and/or performance loss) and performance in the chair stand test. was tested by binary logistic regression technique. The ROC curve parameters were used to evaluate the diagnostic power of the test in sarcopenia screening. The significance level was set at 5 %. Results: The model showed that the time spent for the chair stand test was positively associated (OR = 1.08; 95% CI = 1.01 - 1.16, p = 0.024) to sarcopenia, indicating that, for each 1 second increment in the test performance, the sarcopenia's probability increased by 8% in elderly women. The cut-off point that showed the best balance between sensitivity and specificity was 13 seconds. Conclusion: The performance of chair stand test showed predictive ability for sarcopenia, being an effective and simple screening tool for sarcopenia in elderly women. This test could be used for screening sarcopenic elderly women, allowing early interventions.
