Interventions to increase physical activity in people with COPD: systematic review

Area of Science:

• Pulmonary Medicine
• Rehabilitation Science
• Public Health

Background:

• Chronic obstructive pulmonary disease (COPD) is associated with significant sedentary behavior, exacerbating health issues.
• Increasing physical activity (PA) is crucial for managing COPD and improving patient outcomes.

Purpose of the Study:

• To systematically review interventions aimed at increasing physical activity in individuals with COPD.
• To evaluate the effectiveness and quality of different intervention types.

Main Methods:

• Systematic review of 15 studies (9 quasi-experimental, 6 RCTs) with 761 participants.
• Inclusion criteria required PA as the primary outcome, objectively measured.
• Interventions included pulmonary rehabilitation, exercise only, behavioral only, and combined approaches.

Main Results:

• Eight of 15 studies reported statistically significant increases in PA.
• Effectiveness varied by intervention type, with exercise-only studies having the highest methodological quality.
• Increases in PA were generally modest and not always clinically meaningful; longer interventions showed higher success rates.

Conclusions:

• Current interventions for increasing PA in COPD patients show potential but require further investigation.
• A limited number of high-quality randomized controlled trials hinder definitive conclusions.
• More research is needed to identify effective, scalable interventions for promoting PA in COPD.
