To evaluate the factors associated with functional capacity in patients with chronic kidney disease (CKD). All patients were submitted to six-minute walk test (6MWT), 10-repetition sit-to-stand test (STS-10) and SF-36 health-related quality of life questionnaire (HRQoL). Patients with functional capacity ≥80% exhibited higher education level, family income, body mass index, estimated glomerular filtration rate, and lower age and STS-10 time. Multiple linear regression showed that gender, age, family income, chronic kidney disease stage, STS-10 time, and physical component summary of HRQoL were significantly associated with the 6MWT distance. Functional capacity was significantly associated with gender, age, family income, CKD stage, STS-10 time, and physical component of HRQoL. The progression of CKD has an impact on the decrease in functional capacity in these patients.
