Actieve vergelijker: Intervention Group (IG)
The intervention of active comparator will be education program plus behavioral intervention through physical activity counseling program combined with a monitoring-and-feedback tool.
|
The educational program will consist of 2 classes held once a week, each lasting 90 minutes.
The classes will be based on an education videotape, presentations and group discussions.
The first class will address the asthma education, which will include information about the pathophysiology of asthma, medication and peak flow meter instructions, self-monitoring techniques, environmental control techniques and avoidance strategies.
The second class will be about the current international physical activity recommendations and the importance and benefits of being physically active and maintain a healthy lifestyle.
The behavioural intervention will be performed in 8 weekly goal-setting consultation, face-to-face, each lasting 40 minutes.
Patients will be offered a commercially-available activity tracker to wear during 3 days prior to each consultation.
According to their own PA data and the behavioural change stage, an individual action plan will be established with realistic goals to increase PA.
Each participant will receive individual counselling with the goal of increasing participation in PA and reducing their sedentary time.
Techniques such as weekly goal-setting, motivational interviewing, activity tracker vibration instructions, self-management, positive reinforcement, relapse prevention and strategies to overcome barriers will be included.

Sham-vergelijker: Control Group (CG)
The intervention of sham comparator will be an education program in asthma and physical activity recommendations.
|
The educational program will consist of 2 classes held once a week, each lasting 90 minutes.
The classes will be based on an education videotape, presentations and group discussions.
The first class will address the asthma education, which will include information about the pathophysiology of asthma, medication and peak flow meter instructions, self-monitoring techniques, environmental control techniques and avoidance strategies.
The second class will be about the current international physical activity recommendations and the importance and benefits of being physically active and maintain a healthy lifestyle.

Change in asthma clinical control
Tijdsspanne: Change from baseline asthma clinical control at 8 weeks of intervention
|
Clinical control will be evaluated by the Asthma Control Questionnaire (ACQ).
The ACQ contains 7 items rated on a 7-point scale (0 = without limitation, 6 = maximum limitation), with a higher score indicating worse control.
Scores lower than 0.75 are associated with good asthma control, whereas scores greater than 1.5 are indicative of poorly controlled asthma, and a change of at least 0.5 points in the ACQ score is regarded as clinically significant.

Change in physical activity levels
Tijdsspanne: Change from baseline physical activity levels at 8 weeks of intervention
|
Physical activity and sedentary behaviour will be objectively quantified using a movement sensor (ActiGraph, Pensacola, USA) for 7 consecutive days on the hip using an elastic belt.
Sedentary behaviour will be quantify by the time spent sedentary (< 100 counts/min).

Change in health related quality of life
Tijdsspanne: Change from baseline health related quality of life at 8 weeks of intervention
|
Health related quality of life will be assessed by Asthma Quality Life Questionnaire (AQLQ).
The AQLQ consists of 32 items rated on a 7-point scale (1 = great deal, 7 = not at all) divided into the following 4 domains: activity limitations, symptoms, emotional function and environmental stimuli.
Higher AQLQ scores indicate a better quality of life, and treatments resulting in a 0.5-point increase in scores following an intervention are considered to be clinically effective.

Change in asthma exacerbation
Tijdsspanne: Change from baseline asthma exacerbation at 8 weeks of intervention
|
Asthma exacerbation will be assessed by the following criteria: the use of ≥4 puffs of rescue medication per 24 hours during a 48-hour period, a need for systemic corticosteroids, an unscheduled medical appointment, and either a visit to an emergency room or hospitalization

Change in sleep quality
Tijdsspanne: Change from baseline sleep quality at 8 weeks of intervention
|
Sleep quality will be objectively quantified using a movement sensor (ActiGraph, Pensacola, USA) for 7 consecutive nights on the wrist (non-dominant side).

Change in psychosocial symptoms
Tijdsspanne: Change from baseline psychosocial symptoms at 8 weeks of intervention
|
Symptoms of anxiety and depression symptoms will be assessed by the Hospital Anxiety and Depression scale (HADs), which consists of 14 items divided into 2 subscales (7 for anxiety and 7 for depression).
Each item is scored from 0 to 3, with a maximum score of 21 points for each subscale.
A score greater than 8/9 in each subscale suggests a diagnosis of either anxiety and/or depression.
