Abstract

Chronic obstructive pulmonary disease (COPD) is a common respiratory disease characterized by persistent respiratory symptoms and irreversible airflow obstruction. It is caused by smoking, occupational exposure, and air pollution. It shows a high prevalence, both in South Korea and worldwide. The global COPD prevalence is 11.7%, and a similar prevalence has been reported in South Korea. In the Korea National Health and Nutrition Examination Survey 2010-2016, the prevalence of COPD was found to be between 13.1% to 14.6%. The prevalence of COPD is increasing continuously. Aging, male sex, smoking, and air pollution are risk factors of COPD. However, COPD is strikingly under-recognized given its prevalence. Three million people die annually due to COPD, and the mortality burden of COPD is increasing along with population aging. The socioeconomic burden of COPD is becoming enormous.

  Figure 1 Prevalence of chronic obstructive pulmonary disease (COPD) in adults. The prevalence of COPD in individuals above 40 years old has shown a consistent pattern over the past 10 years, ranging from 11.0% to 15.6% [9]. In this period, COPD was more prevalent in men than in women. The prevalence of COPD was 16.6% to 23.4% in men and 5.8% to 10.2% in women.

  Figure 2 Difference in the prevalence of chronic obstructive pulmonary disease (COPD) between those aged ≥40 years and those aged ≥65 years. COPD was more prevalent in the older age group [9]. From 2007 to 2016, the prevalence of COPD was 23.6% to 34.0% in those aged ≥65 years, in contrast to 11.0% to 15.6% in those aged ≥40 years.

  Figure 3 Disability-adjusted life years (DALYs, 1990 to 2016)) of chronic obstructive pulmonary disease (COPD) in South Korea and other regions. (A) In South Korea, the DALYs per 100,000 people due to COPD continuously increased from 1990 to 2016. (B) The trend of DALYs per 100,000 people for COPD are different by region. The DALYs per 100,000 people for COPD showed the same trend, both in South Korea and Taiwan. However it was different from the trend of Japan or worldwide.
