Abstract
Increases in physical fitness have been associated with improvements in several outcomes in adults with asthma. However, it is unknown whether changes in physical activity level (PAL) affect asthma control.
Aim: To investigate the effects of a behaviour change intervention aimed at increasing PAL on asthma clinical control.
Methods: Adults with moderate-to-severe asthma were randomly assigned to either a control (CG) or an intervention group (IG). Both groups received usual care (pharmacological treatment) and similar educational programme. Participants in the IG also underwent an 8-week behaviour change intervention aimed at increasing PAL. The face-to-face intervention was delivered once weekly and focused on goal-setting and feedback. Before and after the intervention period, assessments were made of: asthma clinical control (ACQ), PAL (GT9X accelerometer), HRQoL (AQLQ) and asthma exacerbation.
Results: 37 participants were included (CG=18; IG=19). On completion of the intervention, compared to the CG, patients in the IG increased PAL (3,291±2,370 vs 249±2,370 steps/day, respectively; p<0.001) and time spent in moderate-to-vigorous PA (16.7±18.5 vs -0.5±9.7 min/day, p<0.001); spent less time in sedentary behavior (7±9 vs 1±6, p<0.01); presented clinical improvements in the ACQ score (-1.2±0.7 vs -0.2±0.7, p<0.01) and AQLQ score (0.6±1.1 vs 0.1±1.2) and had less exacerbations (32 vs 61%, p<0.001). In addition, the increase in PAL was associated with improvements in asthma clinical control (r=0.4, p=0.02).
Conclusion: Our results suggest that the behavioural intervention improved PAL which contributed to better clinical control in adults with asthma.
