Patients with COPD with higher levels of anxiety are more physically active.

Background

Physical activity (PA) has been found to be an excellent predictor of mortality beyond traditional measures in COPD. We aimed to determine the association between depression and anxiety with accelerometry-based PA in patients with COPD.

Results

Increased anxiety was associated with higher levels of PA such that for every one-point increa
