体力活动水平对维持性血液透析患者死亡率的预测价值分析

Predictive Values of Physical Activity Level on Mortality among Maintenance Hemodialysis Patients

目的探讨体力活动水平对维持性血液透析(maintenance hemodialysis,MHD)患者死亡率的预测价值。方法采用方便抽样法,使用7 d体力活动回顾问卷(7-day Physical Activity Recall Questionnaire,PAR)对广州市5家三级甲等医院维持性血液透析的317例患者进行追踪调查。结果体力活动水平可以预测MHD患者的死亡率。轻度体力活动时间、中度体力活动时间、7 d体力活动回顾问卷计算值(PAR值)是MHD患者死亡的保护因素,其值越高,死亡风险越低;年龄是危险因素,其值越高,死亡风险越高。结论体力活动水平可以预测MHD患者的死亡率,患者的体力活动水平越高,死亡风险越低。本研究提示医护人员应该加强对MHD患者体力活动水平的评估,并指导患者进行适当的体力活动,从而降低患者死亡率。

Objective To explore the predictive values of physical activity level on mortality among maintenance hemodialysis （MHD） patients. Methods A convenience sample of 317 patients from 5 Class 11 Grade I hospitals in Guangzhou was recruited. The 7- day Physical Activity Recall Questionnaire （PAR） was used to assess physical activity level among MHD patients. Results Physical activity level can predict the mortality among MHD patients. Mild physical activity time, moderate physical activity time and the value of PAR were protective factors of mortality. The patients with higher physical activity level had lower mortality and age was the risk factor of mortality. Conclusion Physical activity level can predict the mortality among MHD patients. The patients with higher physical activity level have lower mortality. The findings suggest that in order to lower the mortality of MHD patients, it is necessary to assess their physical activity level and provide health instructions on physical activities to them.
