Abstract

The purpose of this study was to identify the degree of quality of life (QoL) and its related factors in patients with Korean Chronic Obstructive Pulmonary Disease (COPD). With data collected by Korea National Health and Nutrition Survey in 2013, general and disease-related variables, pulmonary function test, and EuroQol-5Dimension (EQ-5D) were analyzed. The mean of EQ-5D index was 0.916 in patients with COPD and 0.941 in non-COPD. The EQ-5D index and its sub dimensions (mobility, self-care, usual activity, pain/discomfort, anxiety/depression) of COPD patients were significantly lower than that of non-COPD. However, difference in COPD patients' airway limitation was significant only for self-care of EQ-5D (${\chi}^2=9.50$, p=.013). The related factors of QoL in COPD patients were age, gender, level of education, quartile of household income, smoking status, and number of comorbid diseases. Based on the results, it is important to pay close attention to COPD patients' QoL as well as comprehensive interventions which possibly improve their QoL.

본 연구는 국내 COPD 환자의 삶의 질 정도 및 삶의 질과 관련이 있는 요인을 확인하기 위해 시도되었다. 2013년도 국민건강영양조사의 일반적 및 질병관련 변수, 폐기능검사 결과, 삶의 질(EuroQol-5Dimension) 자료를 이용하여 가중치를 적용한 후 복합표본 교차분석과 복합표본 회귀분석으로 분석하였다. 연구결과, EQ-5D Index는 COPD 환자 0.916점, 정상인 0.941점으로 COPD 환자가 정상인보다 통계적으로 유의하게 낮았다. 삶의 질 하부 영역인 이동, 자가간호, 일상활동, 통증/불편감, 불안/우울 모두 COPD 환자는 정상인과 비교하여 문제 없음의 비율이 낮고 문제 있음의 비율이 높았지만, 기도폐쇄 정도에 따른 삶의 질은 자가간호 영역만 유의한 차이가 있었다 (${\chi}^2=9.50$, p=.013), COPD 환자의 삶의 질과 관련이 있는 요인은 연령, 성별, 교육수준, 가구당 수입, 흡연상태, 동반질환 수이었다. 본 연구결과를 바탕으로, COPD 환자의 삶의 질에 대한 관심과 함께 이동, 자가간호, 일상생활을 증진하고 통증/불편감, 불안/우울을 감소하는 등 삶의 질을 향상시키기 위한 포괄적인 접근이 이루어져야 할 것이다.
