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.
本研究的目的是评估体力活动是否能够预测维持性血液透析（MHD）患者的死亡率。这项观察性研究纳入了2012年2月至6月期间来自山西省人民医院和西安医学院第二附属医院的317例接受MHD治疗的患者。采用人类活动量表（HAP）和斯坦福7日体力活动回忆问卷（PAR）来测量体力活动。无论是否运动，最大活动得分（MAS）、校正活动得分（AAS）、轻度体力活动、中度体力活动以及PAR值均与MHD患者的死亡率显著相关。最大活动得分（MAS）、校正活动得分（AAS）和PAR值较高；轻度体力活动和中度体力活动时间较多的患者死亡率较低。通过多因素Cox回归分析，校正年龄、MAS、PAR值和轻度体力活动后可预测MHD患者的死亡率（P < 0.05），相对风险值分别为0.44、0.69和0.66。基线体力活动是血液透析患者死亡率的独立预测因素。
