不同的因素会导致血液透析(HD)患者久坐不动的生活方式，包括他们在透析上花费的时间。本研究的目的是使用精确的三轴加速度计评估该人群在日常生活中的体力活动特征，并将这些特征与生理变量相关联。使用动态端口加速度计评估了19名HD患者，并与19名对照组进行了比较，比较了他们在日常生活中不同活动和姿势上所花费的时间以及所走的步数。HD患者比对照组更久坐不动，行走或站立的时间更少，躺着的时间更多。久坐的行为在透析日更为明显。根据每天步行的步数，47.4%的血液透析患者被归类为久坐，而对照组为10.5%。血红蛋白水平、肢体肌力、SF-36量表的身体功能与步行时间和活动时间显著相关。准确地观察日常生活中的活动模式，HDS患者更多地坐着，特别是在透析日。应鼓励这些患者加强体力活动。
Different factors can contribute to a sedentary lifestyle among hemodialysis (HD) patients, including the period they spend on dialysis. The aim of this study was to evaluate characteristics of physical activities in daily life in this population by using an accurate triaxial accelerometer and to correlate these characteristics with physiological variables. Nineteen HD patients were evaluated using the Dyna Port accelerometer and compared to nineteen control individuals, regarding the time spent in different activities and positions of daily life and the number of steps taken. HD patients were more sedentary than control individuals, spending less time walking or standing and spending more time lying down. The sedentary behavior was more pronounced on dialysis days. According to the number of steps taken per day, 47.4% of hemodialysis patients were classified as sedentary against 10.5% in control group. Hemoglobin level, lower extremity muscle strength, and physical functioning of SF-36 questionnaire correlated significantly with the walking time and active time. Looking accurately at the patterns of activity in daily life, HDs patients are more sedentary, especially on dialysis days. These patients should be motivated to enhance the physical activity.
