Takeaway

  • The age-adjusted prevalence of COPD is around 50% higher among adults with arthritis than those without arthritis.

Why this matters

  • Clinicians should consider assessing patients with arthritis for COPD for earlier detection and for introducing pulmonary rehabilitation to increase aerobic activity, reduce shortness of breath, pain, and depression.
  • The relationship between COPD and arthritis may be mediated by prolonged systemic inflammation and physical inactivity.

Study design

  • Cross-sectional cohort of 408,774 US adults in the 2016 Behavioral Risk Factor Surveillance System (BRFSS).
  • COPD and arthritis were based on self-reported physician diagnosis.
  • Arthritis included osteoarthritis, rheumatoid arthritis, lupus, gout, and fibromyalgia.

Key results

  • The crude overall prevalence of COPD was 6.4% and arthritis, 25.2%.
  • The prevalence of age-adjusted COPD was greater among participants with arthritis than among those without arthritis (13.7% vs 3.8%; adjusted prevalence ratio was 1.5; P<.001>
  • The association between the two was significant among most subgroups, especially those aged 18-44 years (11.5% vs 2.0%; adjusted prevalence ratio, 2.2; 95% CI, 1.9-2.5) and never smokers (7.6% vs 1.7%; adjusted prevalence ratio, 1.9; 95% CI, 1.7-2.1).

Limitations

  • Cross-sectional, observational design.
