Physical activity has been found to have a positive effect on the clinical outcomes of patients with chronic diseases, including end-stage renal disease (ESRD). The purpose of this study was to describe end-stage renal disease patients on hemodialysis and describe, as well, their physical activity levels.
Participants were recruited from the renal unit of Hospital Universitario in San Juan. The variables of interest were 1) socio-demographic and health status information and 2) physical activity levels and patterns.
Thirty-one participants with end-stage renal disease completed the questionnaires (17 men and 14 women). The average age of the participants was 54+17 years. Eighty-seven percent (87%) answered that they were not active before beginning hemodialysis treatment. Only 4 patients were employed. These four patients performed activities of moderate intensity ranging from 0 to 2267 MET-mins/week. Nineteen participants reported that they performed a variety of household chores. Home physical activity scores consisted of an average of 1025+1856 MET-mins/week (median 200 MET-mins/week). The total physical activity energy expenditure in leisure-time activities was an average of 111+167 MET-mins/ week. The average total physical activity for all the categories from the IPAQ was an average of 1688+2250 MET-mins/week (median 544 MET-mins/week). They sat for about 454+293 minutes per day (approximately 7.5 hours daily). A Spearman's correlation test found there to be a significant inverse relationship between total physical activity energy expenditure and years in hemodialysis treatment, regardless of age (p = -0.301; p < 0.05).
In this study, the author describes the physical inactivity in a group of ESRD patients receiving hemodialysis and the significant physical activity variability among them. Moreover, those participants who had been on hemodialysis the longest tended to be the most sedentary, regardless of age. Therefore, it is important to raise awareness, educate and assess, and, if warranted, recommend physical activity to chronic kidney disease patients, including those with end-stage renal disease who are receiving hemodialysis.
已发现身体活动对包括终末期肾病（ESRD）在内的慢性病患者的临床结局有积极影响。本研究的目的是描述接受血液透析的终末期肾病患者，并描述他们的身体活动水平。
参与者从圣胡安大学医院的肾脏科招募。感兴趣的变量为：1）社会人口统计学和健康状况信息；2）身体活动水平和模式。
31名终末期肾病参与者完成了问卷调查（17名男性和14名女性）。参与者的平均年龄为54±17岁。87%的参与者回答他们在开始血液透析治疗前不活跃。只有4名患者有工作。这4名患者进行中等强度活动，活动量为0至2267代谢当量-分钟/周。19名参与者报告他们进行了各种家务劳动。家庭身体活动得分平均为1025±1856代谢当量-分钟/周（中位数为200代谢当量-分钟/周）。休闲活动中的总身体活动能量消耗平均为111±167代谢当量-分钟/周。国际体力活动问卷（IPAQ）所有类别的平均总身体活动量为1688±2250代谢当量-分钟/周（中位数为544代谢当量-分钟/周）。他们每天坐着的时间约为454±293分钟（约每天7.5小时）。Spearman相关性检验发现，无论年龄如何，总身体活动能量消耗与血液透析治疗年限之间存在显著的负相关关系（p = -0.301；p < 0.05）。
在本研究中，作者描述了一组接受血液透析的终末期肾病患者的身体不活动情况以及他们之间显著的身体活动差异。此外，无论年龄如何，那些接受血液透析时间最长的参与者往往久坐不动。因此，提高认识、进行教育和评估，并在必要时向慢性肾病患者（包括接受血液透析的终末期肾病患者）推荐身体活动非常重要。
