Relation Between Anxiety, Depression, and Physical Activity and Performance in Maintenance Hemodialysis Patients

Objective: Maintenance hemodialysis (MHD) patients have a high prevalence of anxiety and depression and decreased daily physical activity (DPA) and exercise capacity. Because affective disorders may affect DPA and physical performance, we investigated possible relationships between anxiety or depression and DPA and physical performance in relatively healthy MHD patients.Design and Methods: This cross-sectional study included 72 relatively healthy MHD patients and 39 normal adults. DPA was measured for 7 days with an Actigraph Activity Monitor®. Physical performance was assessed using the 6-minute walk (6-MWT), sit-to-stand (STS), and stair-climbing tests. Subjects completed the Beck Anxiety Inventory (BAI), the Beck Depression Inventory-II (BDI), and the Hospital Anxiety and Depression Scale (HADS). Main outcome measures were physical activity counts (expressed as vector magnitude), in the 6-MWT, STS, stair-climbing test, BAI, BDI, and HADS scores.Results: Anxiety and depression by BAI and BDI were identified in 43% and 33% of MHD patients and 2.5% and 5% of normals, respectively (P
