Abstract

Abstract: The aim of this study was to assess whether physical activity can predict mortality in patients undergoing maintenance hemodialysis (MHD). This observational study enrolled 317 patients undergoing MHD from Shanxi Provincial People Hospital and the Second Affiliated Hospital of Xi'an Medical University from February to June 2012. Physical activity was measured by using the Human Activity Profile (HAP) and the Stanford 7‐day Physical Activity Recall Questionnaire (PAR). Exercise or not, maximal activity score (MAS), adjusted activity score (AAS), light physical activities, moderate physical activities, and the PAR value were significantly associated with mortality among patients undergoing MHD. The patients with higher scores of maximal activity score (MAS), adjusted activity score (AAS), and PAR value; more hours of the light physical activities; and moderate physical activities have the lower mortality. Through multivariate Cox regression analysis, adjusting for age, MAS, PAR value, and light physical activities can predict the mortality among patients undergoing MHD (P < .05), and the relative risk values were 0.44, 0.69, and 0.66, respectively. Baseline physical activities are independent predictors of mortality in patients undergoing hemodialysis. SUMMARY STATEMENT: What is already known about the topic? Many studies had showed that MHD experience high rates of mortality. However, few studies have found variables capable of predicting mortality of the patients. If predictive variables were identified, they could be used to develop effective measures that would, in time, lower mortality. What this paper add? This study demonstrated that exercise is beneficial for patients undergoing hemodialysis and that physical activity can predict the mortality of patients undergoing hemodialysis. The implication of this paper: Patients undergoing hemodialysis should be encouraged to increase their level of physical activity. More studies of physical activity in hemodialysis patients are needed. In line with study findings, guidelines should be formulated to support physical activity for patients undergoing hemodialysis.
