Abstract

The association between characteristics of sleep and physical activity in daily life (PADL) was not yet investigated in depth in subjects with chronic obstructive pulmonary disease (COPD). This study evaluated if time spent/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 (6 MWT).

Fifty-five subjects with moderate-to-severe COPD (28 male, 67±8 years) were studied. Subjects with total time in bed/night (TIB) ≥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<0.05 for all). Subjects with TIB≥9 h also spent more time/day in sedentary behaviour and less time/day in PA of light and moderate-to-vigorous intensity than those with TIB 7–9 h and ≤7 h. In multiple linear regression, TIB≥9 h was the only significant predictor of physical inactivity (β=−3.3 [−5.1, −1,6], p≤0.0001), accounting for 20% of its variation. Sleep fragmentation was frequent and more pronounced in physically inactive than active patients (7.5 [6.3–9.6] versus 6.4 [5.5–7.3] sleeping bouts; p=0.027).

In summary, subjects with COPD with time in bed ≥9 h·night−1 have more fragmented sleep, are more sedentary and less physically active than those with <9 h·night−1, independently of the awake time. Sleep quality is frequently poor and even worse in patients classified as physically inactive.
