BMC Pulmonary Medicine

Table 5 Differences across disease severity for sedentary behavior, physical activity and exercise capacity for patients with bronchiectasis

	Disease severity: Mild BSI score ≤ 4(n = 27)	Disease severity: Moderate/severe BSI score ≥ 5(n = 28)
Sedentary behavior time (mins/day)	632 (64)	635 (88)
Light-lifestyle physical activity time (mins/day)	210 (55)	204 (71)
Total MVPA time (mins/day)	32 (19)	18 (18)^a
MVPA₁₀₊ time (mins/day)	8 (10)	5 (8)
Activity energy expenditure (kcals/day)	390 (173)	231 (159)^b
Daily step counts	6898 (2783)	5137 (2532)^c
Total physical activity time (mins/day)	242 (65)	221 (84)
MST (metres)	593 (323)	432 (199)^d

Results are Mean (SD).
Note: Disease severity expressed as Bronchiectasis Severity Index score [22].
