Behavioral Intervention to Increase Physical Activity in Patients With Asthma

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.
