Abstract
Aim:People with chronic obstructive pulmonary disease (COPD) demonstrate low levels of physical activity [1]. Literature suggests that physical activity interventions including behaviour change techniques could help to improve activity levels in those with COPD [2]. This systematic review and meta-analysis aimed to examine behaviour change interventions that promote physical activity for adults with COPD.
Methods:
Nine databases were searched from inception until February 2022: Web of Science, CENTRAL, MEDLINE, EMBASE, APA PsychINFO, CINAHL, PROSPERO, Cochrane Airways Trials Register. Included studies were reviewed to determine the impact of behaviour change interventions on physical activity and quality of life outcomes. Behaviour change interventions were mapped to Michie’s Theoretical Domains Framework (TDF) and a meta-analysis and narrative synthesis was conducted. The Cochrane risk of bias tool and the GRADE criteria were utilized to evaluate bias and the quality and certainty of the evidence.
Results:
Twelve randomized controlled trials (RCTs) were included in the review (n= 1211). Steps per day, physical activity levels, exercise capacity and quality of life were the most commonly utilized outcome measures across the studies. Counselling, stepcount monitoring, social support and goal setting were identified as the most frequently used behaviour change interventions. A meta-analysis of comparable studies demonstrated that behaviour change interventions had no significant long-term impact on steps per day when compared to control groups (SMD 0.16, 95% CI -0.03, 0.36; p=0.10). When mapped to the TDF, the domains of goals, behaviour regulation and social influences related to some significant short-term (upto 12 weeks) improvements in physical activity and quality of life outcomes across six studies only.
Conclusion:
People with COPD may benefit, in the short-term, from behaviour change interventions to improve their physical activity behaviour and quality of life, however, long-term benefits are less clear. The overall certainty and quality of the evidence is low.
