Abstract

Background: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation that is not fully reversible. COPD has systemic effects, such as skeletal muscle dysfunction and abnormal weight loss. It also has been suggested that COPD is related to other chronic disease, such as cardiovascular disease, osteoporosis, and anemia. The aim of this study was to evaluate a symptom questionnaire and laboratory findings in subjects with air flow limitation. Methods: We evaluated a symptom questionnaire and laboratory findings in subjects with airflow limitation detected by spirometry in conjunction with the Second Korean National Health and Nutrition Examination Survey. A total of 9,243 adults over the age of 18 were recruited. Among the adults, we finally analyzed 2,217 subjects who met the acceptability and repeatability criteria of spirometry, showed normal findings on chest radiography, and were older than 40 years of age. Results: There were 288 subjects with airflow limitation as determined by spirometry. The frequency of respiratory symptoms such as cough, sputum and wheezing were significantly higher in subjects with airflow limitation (p <0.01). Hemoglobin and hematocrit levels were higher in subjects with airflow limitation (hemoglobin level 13.98 mg/dL vs. 13.62 mg/dL, hematocrit 42.10% vs. 40.89%; p<0.01). The HDL cholesterol level was lower in subjects with airflow limitation (44.95 mg/dL vs. 45.60 mg/dL; p<0.01). There was no significant difference in the total cholesterol, triglyceride, blood urea nitrogen, creatinine, and fasting glucose levels. Conclusion: In subjects with airflow limitation, prevalence of respiratory symptoms was higher than in normal spirometry subjects and the levels of hemoglobin and the hematocrit were higher. The HDL cholesterol level was lower in subjects with airflow limitation.

연구배경: 만성폐쇄성폐질환은 여러 중요한 사망 원인 중 전세계적으로 유일하게 유병률이 증가하고 있는 질환이다 만성폐쇄성폐질환은 폐 이외의 다른 장기에도 영향을 끼치는 전신 질환으로 이해되고 있다. 본 연구는 폐활량 검사에서 기류 폐쇄 유무에 따른 호흡기 증상 빈도와 검사실 성적에 대해 알아보고자 하였다. 방 법: 2001년 국민건강영양조사와 같이 시행된 국가 단위 만성폐쇄성폐질환 유병률 조사에 참여한 대상으로 연구가 수행되었다. 본 연구는 폐활량 검사를 실시하여 GOLD 진단 기준으로 기류 폐쇄가 있는 대상과 없는 대상으로 구분하여 총 콜레스테롤, 혈액요소질소, 크레아티닌, 혈색소, 적혈구용적율, 공복 혈당, 고밀도 콜레스테롤, 중성지방의 평균값의 차이가 있는지를 알아 보았고 설문 조사를 통한 호흡기 증상의 빈도를 확인하였다. 결 과: 총 2,217명이 연구대상에 포함되었다. 이 중 GOLD 진단 기준에 따라 기류 폐쇄가 있는 대상이 288명, 기류 폐쇄가 없는 대상이 1,929명이었다. 호흡곤란을 느낀 적이 있다고 대답하였으나 기류 폐쇄의 유무에 따른 차이는 없었다. 기류 폐쇄가 있는 연구 대상들은 기류 폐쇄가 없는 대상들보다 객담, 기침, 천명음 등의 증상을 더 많이 호소하였다. 폐기능이 나쁠수록 호흡기 증상을 호소하는 연구 대상이 통계적으로 유의하게 더 많았다. 혈색소, 적혈구용적률의 평균값은 기류 폐쇄가 있는 군에서 더 높게 측정 되었으며 고밀도 콜레스테롤의 평균값은 기류 폐쇄가 있는 군이 통계적으로 낮게 측정 되었다. 총콜레스테롤, 중성지방, 혈액요소질소, 크레아티닌, 공복 혈당의 평균값은 기류 폐쇄 유무에 상관 없이 양군간에 차이는 없었다. 결 론: 기류 폐쇄가 없는 연구 대상에 비해 기침, 객담, 천명음과 같은 호흡기 증상의 경험 빈도가 많았고 혈액 검사에서 혈색소, 적혈구용적률의 평균값은 컸으며 고밀도 콜레스테롤의 평균값은 낮았다. 운동시 호흡곤란의 빈도, 총 콜레스테롤, 중성지방, 공복 혈당, 총 콜레스테롤, 혈액요소질소, 크레아티닌의 평균값은 기류 폐쇄의 유무와 상관 없었다.
