Previous studies have observed worse sleep quality in patients undergoing conventional dialysis as compared to daily dialysis. Our aim was to compare the sleep parameters of patients undergoing daily or conventional dialysis using an objective measure (actigraphy). This cross-sectional study was performed in three dialysis centers, including a convenience sample (nonprobability sampling) of 73 patients (36 patients on daily hemodialysis and 37 patients on conventional hemodialysis). The following parameters were evaluated: nocturnal total sleep time (NTST), expressed in minutes; wake time after sleep onset (WASO), expressed in minutes; number of nighttime awakenings; daytime total sleep time (DTST), expressed in minutes; number of daytime naps; and nighttime percentage of sleep (% sleep). The Mini-Mental State Examination and the Beck Depression Inventory were also administered. The mean age was 53.4 ± 17.0 years. After adjustment of confounding factors using multiple linear regression analysis, no difference in actigraphy parameters was detected between the groups: NTST ( = 0.468), WASO ( = 0.88), % sleep ( = 0.754), awakenings ( = 0.648), naps ( = 0.414), and DTST ( = 0.805). Different from previous studies employing qualitative analysis, the present assessment did not observe an influence of hemodialysis modality on objective sleep parameters in chronic renal patients.
以往研究发现，与每日透析的患者相比，接受常规透析的患者睡眠质量更差。我们的目的是使用客观测量方法（活动记录仪）比较每日透析或常规透析患者的睡眠参数。这项横断面研究在三个透析中心进行，纳入了73例患者的便利样本（非概率抽样）（36例每日血液透析患者和37例常规血液透析患者）。评估了以下参数：夜间总睡眠时间（NTST），以分钟为单位；睡眠开始后的清醒时间（WASO），以分钟为单位；夜间觉醒次数；白天总睡眠时间（DTST），以分钟为单位；白天小睡次数；以及夜间睡眠百分比（%睡眠）。还进行了简易精神状态检查和贝克抑郁量表评估。平均年龄为53.4 ± 17.0岁。使用多元线性回归分析调整混杂因素后，两组之间未检测到活动记录仪参数的差异：NTST（ = 0.468）、WASO（ = 0.88）、%睡眠（ = 0.754）、觉醒（ = 0.648）、小睡（ = 0.414）和DTST（ = 0.805）。与以往采用定性分析的研究不同，本评估未观察到血液透析方式对慢性肾病患者客观睡眠参数的影响。
