Sedentary behavior in individuals with diabetic chronic kidney disease and maintenance hemodialysis.

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. Subjects One hundred sixty patients with chronic kidney disease (CKD) or receiving maintenance hemodialysis (MHD). Methods Standardized questionnaires including Baecke physical activity questionnaire, standardized anthropometry examination, and blood draw. Main Outcome Measure Sedentary behavior (defined as answering "very often" for "during leisure time I watch television" or answering "never" for "during leisure time I walk") and being physically active (top 25th percentile of the total Baecke score). Results Nineteen percent of CKD and 50% of MHD patients were sedentary ( P Conclusions Sedentary behavior is highly prevalent among diabetic CKD or MHD patients. The strong association of MHD status with sedentary behavior is not explained by demographics, smoking, comorbidity, nutritional, and inflammatory markers. Interventions targeting obesity might improve sedentary behavior and physical activity, whereas interventions targeting inflammation might improve physical activity in these populations.
