Despite the high prevalence of sleep disturbances in idiopathic pulmonary fibrosis (IPF), the relationship between physical activity in daily life (PADL) and sleep in this population remains unclear.
Investigate the impact of sleep on different domains of PADL in IPF and characterize their PADL profile.
Sixty-seven participants (thirty-three with IPF and thirty-four healthy subjects [control group]) were included. The subjects underwent assessments of pulmonary function, exercise capacity, respiratory and peripheral muscle strength, PADL, sleep, dyspnea, and health-related quality of life. PADL and sleep measures were assessed using an activity monitor (Actigraph®, wGT3x-BT). Associations between sleep and PADL were done using correlation and regression models.
In the IPF, sleep duration at night associated significantly with step counts, sedentary, light, and moderate-to-vigorous physical activity (MVPA) (-0.82 ≤ R ≤ 0.43; p < .05 for all). Lung function and sleep partially explained PADL variables (0.19 ≤ R ≤ 0.65, p < .05 for all). Compared to controls, the IPF subjects presented lower step counts, less time spent in MVPA, standing position, and more time spent in lying position (p < .05, for all).
Sleep duration is associated with PADL in IPF. The PADL profile of patients is worse than in control subjects.
尽管特发性肺纤维化（IPF）患者中睡眠障碍的患病率很高，但该人群的日常生活体力活动（PADL）与睡眠之间的关系仍不清楚。
研究睡眠对 IPF 患者不同 PADL 领域的影响，并描述其 PADL 特征。
纳入 67 名参与者（33 名 IPF 患者和 34 名健康受试者[对照组]）。对受试者进行肺功能、运动能力、呼吸和外周肌肉力量、PADL、睡眠、呼吸困难和健康相关生活质量评估。使用活动监测仪（Actigraph®，wGT3x-BT）评估 PADL 和睡眠。使用相关和回归模型评估睡眠与 PADL 之间的关系。
在 IPF 患者中，夜间睡眠时间与步数、久坐、低强度、中高强度体力活动（MVPA）呈显著相关（-0.82≤R≤0.43；所有 p 值均<.05）。肺功能和睡眠部分解释了 PADL 变量（0.19≤R≤0.65，所有 p 值均<.05）。与对照组相比，IPF 患者的步数较少，MVPA、站立和卧位时间较少（所有 p 值均<.05）。
IPF 患者的睡眠时间与 PADL 相关。患者的 PADL 特征比对照组差。
