초록

연구배경: 만성폐쇄성폐질환(chronic obstructive pulmonary disease, COPD) 환자군에서 우울증 및 불안장애의 유병률이 높고, 이는 치료경과 및 사망률에도 영향을 주는 것으로 알려져 있다. 저자들은 국내연구가 미비한 COPD환자들의 우울과 불안심리에 대한 평가를 하고자 하였다. 방 법: 2005년 9월부터 2006년 8월까지 이화의료원 호흡기내과에서 외래치료 중인 72명의 COPD환자와 정상 대조군 50명에서 Beck Depression Inventory (BDI)와 State-Trait Anxiety Inventory (STAI)로 설문조사를 시행하였고, 임상기록을 분석하였다. 결 과: 1) 연령과 체질량지수, 혈청 알부민 수치는 환자군과 대조군간의 유의한 차이를 보이지 않았다(p>0.05). 우울심리는 BDI점수가 환자군 16(0-37), 대조군 12(1-30)으로 환자군에서 유의하게 높았고(p=0.001), 21점 이상의 우울집단은 환자군이 36%로 대조군 6%에 비해 많았다(p<0.0001). 환자군에서는 경증군 18%(4/22), 중등증군 30%(6/20), 중증군 52%(13/25), 심한 중증군 60%(3/5)로 중증일수록 빈도가 높았다(p=0.008). 2) 불안심리는 환자군에서 SAI 점수 44(20-67), TAI점수 47(20-66)로 각각 대조군 39(26-65), 44(33-90)보다 유의하게 높았다(p=0.005, p=0.022). 환자군에서 BDI와 STAI점수는 상관관계를 보였고(p<0.001), 우울집단에서 불안점수가 유의하게 높았다. 3) COPD환자군에서 우울집단은 비우울집단보다 체질량지수, 기관지확장제후 $FEV_1$의 예측치가 유의하게 낮았고, 현재 흡연자의 비율과 중증도, STAI점수가 유의하게 높았다(p<0.05). 4) 연령과 성별을 통제한 다변량 로지스틱 회귀분석상 95% 신뢰구간으로 비차비는 체질량지수 0.9(p=0.311), 현재 흡연자 3.2(p=0.051), 중증군이상 3.9로(p=0.027), 중증이상의 중증도가 유일한 우울증 발생의 독립적 위험요인이었다. 결 론: COPD환자군에서 우울증과 불안심리가 흔하게 관찰되며, 체질량지수, 폐기능, 현재 흡연력이 우울관련 요인으로 특히 중증도가 높을수록 우울증과 불안장애의 관리가 필요함을 보여주었다.

Background: Patients with chronic obstructive pulmonary disease (COPD) have often been reported to suffer from depression and anxiety possibly due to the exacerbation, hospitalization and mortality of COPD. However,scarce data are available in Korea. This study assessed degree of depression and anxiety, and evaluated the factors associated with depressive symptoms in COPD. Methods: The cross-sectional data on the lung function measurements, smoking behavior, body mass index (BMI), age, gender, depressive symptoms using Beck Depression Inventory (BDI) and anxiety using the State-Trait Anxiety Inventory (STAI) were evaluated in 72 outpatients with COPD and 50 controls without underling lung diseases from September, 2005 to October, 2006 in the Ewha medical center. Results: 1) The age, body mass index (BMI) and serum albumin levels were similar in the patients and controls. The BDI scores (16(0-37) vs. 12(1-30), p=0.001) and the prevalence of depression (36% vs. 6%, p<0.0001) were higher in the COPD patients than in the controls. In the COPD group, the prevalence of depression increased with increasing GOLD stage (p=0.008). The prevalence was 18%(4/22), in mild cases, 30%(6/20) in moderate cases, 52%(13/25) in severe cases and 60%(3/5) in very severe cases. 2) The SAI and TAI scores were higher in the COPD patients (44(20-67) and 47(20-66)) than in the healthy controls (39(26-65) and 44(33-90)). There were a significant correlation between the depression and anxiety scores (p<0.001). 3) A lower BMI, lower postbronchodilator $FEV_1$, current smoking behavior and severity of COPD were univariately associated with the depressive group in COPD, 4) while multivariate logistic analysis revealed only the severe-to-very severe group (OR 3.9, 95% CI 1.2 to 12.9) to be independently associated with depressive symptoms. Conclusion: COPD is strongly associated with depression and anxiety. Therfore, screening for psychological problems in COPD patients is essential, particularly in patients with severe-to-very severe COPD.
