Methods: A cross-sectional analysis examined 2356 subjects (1178 COPD patients, 1178 control subjects) aged ≥40years and performed reliable spirometry as part of KNHANES IV-V. Baseline EQ-5D visual analog scale (VAS) and EQ-5D utility scores were obtained. A Tobit censored regression model was used to evaluate factors affecting EQ-5D in COPD patients. Results: The EQ-5D VAS and EQ-5D utility scores were significantly different among the COPD severity groups (P<0.05). The mean EQ-5D VAS scores for patients with mild, moderate, and severe COPD were 73.0 (SD 18.6), 70.8 (19.1), and 60.9 (23.4), respectively. The mean utility scores were 0.90 (0.14) for patients with mild COPD, 0.89 (0.14) for patients with moderate COPD, and 0.84 (0.15) for patients with severe COPD. Factors influencing the EQ-5D utility score in patients with COPD were age, gender, household income, education level, severe airflow obstruction, and comorbidities. Conclusions: The EQ-5D score could be a useful instrument for evaluating the quality of life of COPD patients in Korea. In Korean COPD patients, the main determinants of EQ-5D scores include older age, female gender, lower household income, lower education level, severe airflow obstruction, and many comorbid diseases.
