Self reproted physical activity in the dialysis population

描述(由申请人提供)：关于“透析患者自我报告的体力活动”的拟议研究提供了迄今为止最大的一组透析患者的体力活动信息。体力活动已被证明可以降低普通人群的心血管发病率和死亡率。在终末期肾病人群中，心血管疾病导致的死亡人数超过50%。因此，重要的是描述和了解这一人群中体力活动的一些障碍。我们建议的研究使用了从1600多名刚刚开始透析的患者的调查中收集的数据。我们计划通过一份问卷来描述他们的体力活动水平。这份问卷多年来一直用于描述患有心脏病和关节炎等疾病的人的体力活动。我们建议的研究将使我们能够比较透析患者和其他慢性病患者的体力活动水平，并了解哪些特征与较高和较低的活动水平有关。 虽然接受透析的患者，特别是血液透析患者，可以在透析中心参加锻炼计划，但还没有实施正式的锻炼计划指南。需要对体力活动、存活率和特定原因住院之间的相关性进行分析，以促进此类干预。我们将分析更高水平的运动是否会延长接受透析的人的寿命或减少他们的住院次数，这反过来将有助于提供更多关于体力活动是否对他们有益的信息。

DESCRIPTION (provided by applicant): The proposed research on "Self reported physical activity in dialysis patient" supplies information about physical activity from the largest cohort of dialysis patients to date. Physical activity has been to shown to decrease cardiovascular morbidity and mortality in the general population. Cardiovascular disease causes more than 50 percent of the deaths within the end stage renal disease population. Therefore it is important to describe and to understand some of the barriers to physical activity within this population. Our proposed study uses data that have already been collected from a survey of over 1600 patients just beginning dialysis. We plan to describe their level of physical activity from a questionnaire. This questionnaire has been used for many years in describing physical activity among persons with diseases such as heart disease and arthritis. Our proposed study will allow us to compare levels of physical activity for persons on dialysis to persons with other chronic diseases, and to understand which characteristics are associated with higher and lower levels of activity. While patients getting dialysis, particularly hemodialysis, could feasibly participate in an exercise program while at a dialysis center, no formal guidelines for exercise programs have been implemented. An analysis examining the correlation between physical activity, and survival and cause specific hospitalization is needed to motivate such interventions. We will analyze whether a higher level of activity increases the lifespan or decreases the number of hospitalizations for people on dialysis, which in turn will help supply more information about whether physical activity is beneficial for them.
