Bidirectional Associations Between Clinically Relevant Depression or Anxiety and COPD: A Systematic Review and Meta-analysis.
The longitudinal associations between depression or anxiety and COPD, and their comorbid effect on prognosis, have not been adequately addressed by previous reviews. We aimed to systematically assess these associations to inform guidelines and practice. ⋯ Depression and anxiety adversely affect prognosis in COPD, conferring an increased risk of exacerbation and possibly death. Conversely, COPD increases the risk of developing depression. These bidirectional associations suggest potential usefulness of screening for these disease combinations to direct timely therapeutic intervention.
