Popis: The association between characteristics of sleep and physical activity in daily life (PADL) has not yet been investigated in depth in subjects with COPD. This study evaluated whether time spent per day in physical activity (PA) and sedentary behaviour are associated with sleep quantity and quality in this population. Sleep and PADL were objectively assessed by an activity monitor for 7 days and analysed on a minute-by-minute basis. Subjects also underwent spirometry and 6-min walking test (6MWT). Fifty-five subjects with moderate-to-severe COPD (28 male, 67±8 years) were studied. Subjects with total time in bed (TIB) per night ≥9 h had higher wake-after-sleep onset than TIB 7–9 h and TIB ≤7 h (195 (147–218) versus 117 (75–167) and 106 (84–156) min) and more fragmented sleep than TIB ≤7 h (8.2 (6.7–14.3) versus 6.3 (5.6–6.9) sleeping bouts; p
