Objective: The objective of this study was to examine whether more advanced kidney failure is associated with sedentary behavior and whether demographics, comorbidity, nutritional, and inflammatory markers explain this association.
Design: Observational study.
Setting: Outpatients recruited from outpatient clinics and dialysis units.
