Analysis of Risk Factors for COPD Incidence in Adults Over 40 Years of Age in Korea

PURPOSE:The purpose of this study is to identify the incidence of chronic obstructive pulmonary disease (COPD) and risk factors for diseases in adults over 40 years of age in Korea, and to provide basic data for the prevention of COPD incidence through management. METHODS: Based on the 2019 data of the Korea NationalHealth and Nutrition Examination Survey (KNHANES), 1,788 adults over the age of 40 who participated in pulmonary function test and health survey were selected as subjects.COPD incidence risk factors were analyzed using complex sample multiple logistic regression analysis. RESULTS:As a result of the analysis, the incidence of COPD in Korea was 11.5%, and the risk of developing COPD was higher in men, age, and current smokers.Compared to women, men had an increased risk of developing COPD by 2.369 times (95% CI 1.289-4.355).In age, the risk of COPD incidence increased by 3.702-fold (95% CI 1.923-7.124) in their 50s, 11.238-fold (95% CI 6.009-21.017) in their 60s, and
