Sarcopenia has a high prevalence in older adults and is associated with chronic aggravations to health, so therefore it is important to identify older adults who are affected by sarcopenia in order to establish preventative strategies or early interventions. To estimate the prevalence of probable sarcopenia and verify its association with cognitive impairment, fear of falling, depressive symptoms and health self-perception in community-dwelling older adults. A cross-sectional study with simple random sampling including 306 older adults of both genders. The outcome variable was probable sarcopenia evaluated by the Five times sit-to-stand test (5XSST) considering probable sarcopenia when the measured time was > 15 seconds, following the recommendation of the European Working Group on Sarcopenia in Older People. The predictor variables were cognitive impairment, fear of falling, depressive symptoms and self-perception of health. Multivariate Logistic Regression was performed to verify associations between the variables. The prevalence of probable sarcopenia was 50.00%. The older adults had significantly higher chances of presenting probable sarcopenia when displaying cognitive impairment (OR 2.49; 95%CI 1.46-4.24), fear of falls (OR 4.23; 95%CI 2.51-7.12), depressive symptoms (OR 2.20; 95%CI 1.32-3.67), poor (OR 2.48; 95%CI 1.19-5.16) and fair self-perception of health (OR 2.11; 95%CI 1.22-3.63) when compared to those who did not have the same conditions. The prevalence of probable sarcopenia in this study was 50.00%, and was associated with the presence of depressive symptoms, cognitive impairment, fear of falls and negative self-perception of health.
