Ten-Year Cumulative Incidence of COPD and Risk Factors for Incident Disease in a Symptomatic Cohort

In this cohort, the 10-year cumulative incidence of COPD was 8.2% (using BTS criteria) and 13.5% (using GOLD criteria). Increasing age, smoking, and bronchitic symptoms, but not gender, were risk factors for incident COPD. GOLD stage 0 therefore appears to identify subjects who are at risk of COPD, but men and women presented different risk profiles.
