Restrictive Lung Disease Incidence and Risk Factors in Korea

The purpose of this study is to identify the incidence of restrictive lung disease (RLD) and risk factors for diseases in adults over 40 years of age in Korea, and to provide basic data for preventing the occurrence of RLD through management. Based on the 2019 data of the Korea National Health and Nutrition Examination Survey, 1,835 adults over 40 years of age who participated in lung function tests and health surveys were selected as subjects. Risk factors for RLD occurrence were analyzed using complex sample multiple logistic regression. As a result of the analysis, the incidence of RLD in Korea was 14.4%, and the risk of RLD was higher for men, older age groups, and obesity based on body mass index and waist circumference. In order to reduce the incidence of RLD, preventive interventions and education that can improve lifestyle habits are required for subjects with RLD risk factors.
