背景透析患者的体力活动比肾功能正常的久坐者少。为了评估不活动的后果和终末期肾病（ESRD）人群中增加活动的努力的结果，需要有效的工具来测量这组人群的身体活动和身体功能。我们进行了一项横断面研究，以确定ESRD的有效性的几个问卷，旨在衡量身体活动或身体功能的一般人群。研究资料包括斯坦福大学7天体力活动回忆问卷（PAR）、老年人体力活动量表（PASE）、人类活动概况（HAP）和医学结局研究简表36项问卷（SF-36）。在七天的时间内使用三维活动监视器（加速度计）测量身体活动（“金标准”）。患者还接受了身体性能测试，包括测量步态速度，爬楼梯时间和椅子上升时间。研究问卷进行管理，并将问卷结果相互比较，并与活动监测和体能测试结果进行比较。39名维持性血液透析患者参加了这项研究。透析患者在所有测试中的得分均低于先前公布的健康标准。所有问卷都与七天的加速度计和至少一项身体表现指标相关。HAP与加速度计相关性最好（r = 0.78，P < 0.0001）。通过加速度测量法测量的身体活动的75%的变化可以通过结合HAP和PASE的信息的模型来解释。SF-36的HAP和身体功能量表与身体机能指标的相关性大致相同。这些问卷在血液透析患者中有效，应用于进一步研究该人群的体力活动和康复努力。
Background. Patients on dialysis are less physically active than sedentary persons with normal kidney function. To assess the consequences of inactivity and the results of efforts to increase activity in the end-stage renal disease (ESRD) population, valid instruments to measure physical activity and physical functioning in this group are needed.Methods. We performed a cross-sectional study to establish the validity in ESRD of several questionnaires designed to measure physical activity or physical functioning in the general population. Questionnaires studied included the Stanford 7-day Physical Activity Recall questionnaire (PAR), the Physical Activity Scale for the Elderly (PASE), the Human Activity Profile (HAP), and the Medical Outcomes Study Short Form 36-item questionnaire (SF-36). Physical activity was measured using three-dimensional activity monitors (accelerometers) over a seven-day period (the "gold standard"). Patients also underwent physical performance tests, including measurement of gait speed, stair climbing time, and chair rising time. Study questionnaires were administered, and questionnaire results were compared with each other and with activity monitor and physical performance test results.Results. Thirty-nine maintenance hemodialysis patients participated in the study. Dialysis patients scored worse than previously published healthy norms on all tests. All questionnaires correlated with seven-day accelerometry and with at least one measure of physical performance. The HAP correlated best with accelerometry (r = 0.78, P < 0.0001). Seventy-five percent of the variability in physical activity measured by accelerometry could be explained by a model that combined information from the HAP and the PASE. The HAP and the physical functioning scale of the SF-36 were about equally well correlated with physical performance measures.Conclusions. These questionnaires are valid in patients on hemodialysis and should be used to study the physical activity and rehabilitation efforts in this population further.
