SESSION TITLE: Airways 4

SESSION TYPE: Original Investigation Poster

PURPOSE: The aim of this study was to identify subtypes in patients with mild to moderate airflow limitation and to evaluate clinical and socioeconomic implications of these subtypes.

METHODS: We analyzed data from the fourth Korean National Health and Nutrition Examination Survey and National Health Insurance claims in 2007-2012. Subjects who were 19 years old and more and had forced expiratory volume in 1 second (FEV1) ≥ 60% predicted and a ratio of FEV1 to forced vital capacity (FVC) < 0.7 were included. K-means clustering was performed to explore subtypes. For clustering analysis, six key input variables, age, body mass index (BMI), FEV1 % predicted, the presence or absence of self-reported wheezing, smoking status, and pack-years of smoking, were selected.
