Physical Activity Behavioral Change Intervention in Lung Cancer

Patients with lung cancer are characterized by having low levels of physical activity (PA) and high sedentary behavior (SB), with direct impact on their quality of life, complications and survival. Previous studies have observed that PA programs have high dropout rates and are not very sustainable over time, making it necessary to incorporate models that consider the preferences and possibilities of patients. Objectives: To compare the effects on PA levels and SB of a 6-month personalized program vs. conventional care, in community-dwelling lung cancer survivors. Methods: Controlled and randomized pilot study, with intervention and control group, pilot study. 40 non-small cell lung cancer survivors (18 to 70 years old) will be included. The control group will receive the usual recommendations regarding an active and healthy lifestyle. The intervention group will follow a personalized PA and behavior change program in the community, supervised by a physiotherapist expert in therapeutic exercise. PA and SB measurements will be carried out using accelerometry and self-reported questionnaires. As secondary variables, functional capacity, lung function, dyspnea and fatigue, as well as quality of life will be measured. A motivational interview will be conducted to personalize the intervention considering clinical characteristics, treatment, motivation and preferences. The intervention will be re-evaluated and adapted monthly, considering the results reported weekly. Through covariance analysis, the levels of PA and SB, among other factors, measured at the beginning and at the end of the intervention will be evaluated.
