COPD was associated with a greater risk of anxiety in multivariable analysis (OR 1.85). Among patients with COPD, anxiety was related to poorer health outcomes including worse submaximal exercise performance (less distance walked during the 6-min walk test) and a greater risk of self-reported functional limitations.
Subjects with COPD with anxiety had a higher risk of COPD exacerbations.
COPD is associated with a higher risk of anxiety. Once anxiety develops among patients with COPD, it is related to poorer health outcomes.

Dr RW: I don't have the full text of this paper, and I wonder if they controlled for continued smoking. Nicotine is a powerful anxiolytic for some COPD patients.
