Background: COPD is a leading cause of chronic morbidity and mortality. However, few studies have measured its incidence rate. In this study, we analyzed prevalence and incidence rate of COPD using community based cohort database.
Method: Ansung-Ansan cohort is an ongoing community-based prospective cohort of 10,038 participants aged 40 to 69 year. COPD was defined as a forced expiratory volume in 1s (FEV1)/forced vital capacity (FVC) ratio ＜0.7. We calculated the prevalence and incidence rate of COPD from 2001 to 2005. And we analyzed the factors associated with prevalence and incidence of COPD.
Results: In this study, the prevalence of COPD was increased from 8.8% (2001) to 13.3% (2005). In terms of severity of airway obstruction, the prevalence of mild COPD has increased most among COPD group. The overall crude incidence rate of COPD per 100,000 person-year was 1447.8 and standardized incidence rate corrected by standard Korean population was 1550.1 The incidence rate of COPD was higher in men than in women and increased with increasing age.
Conclusion: We demonstrated the prevalence and incidence rate of COPD in Korean adult population with community based cohort database.
