Abstract:: BACKGROUND: Symptoms of depression, pain and limitations in physical activity may affect quality of life in COPD patients independent from their respiratory burden. We aimed to analyze the associations of these factors in outpatients with COPD in Austria in a stable phase of disease. METHODS: We conducted a national, cross-sectional study among patients with COPD. For depression, the Patient Health Questionnaire-9 (PHQ-9) and for respiratory symptoms the St. George's Respiratory Questionnaire for COPD patients (SGRQ-C) were used along with 10-point scales for physical activity and pain. RESULTS: After exclusion of 211 patients due to non-obstructive spirometry or missing data, 630 patients (62.5% men; mean age 66.8 ± 8.6 (SD) years; mean FEV₁%pred. 54.3 ± 16.5 (SD)) were analyzed. Of these, 47% reported one or more exacerbations in the previous year, 10.4% with hospitalization. A negative depression score was found in 54% and a score suggesting severe depression (PHQ-9 score ≥ 15) in 4.7%. In a multivariate linear regression model, self-reported pain, dyspnea, and number of exacerbations were predictors for higher PHQ-9-scores. A negative pain score was found in 43.8%, and a score suggesting severe pain in 2.9% (8-10 points of 10-point scale). Patients reporting severe pain were more often female, had more exacerbations, and reported more respiratory and depressive symptoms, a lower quality of life, and less physical activity. About 46% of patients rated their physical activity as severely impaired. These patients were significantly older, had more exacerbations, concomitant heart disease, a higher pain and depression score, and a lower quality of life (SGRQ-C - total score and all subscores). CONCLUSIONS: In Austria, nearly half of stable COPD outpatients reported symptoms of depression, which were associated with lower levels of self-reported physical activity, more pain, and respiratory symptoms. The associations were particularly strong for depression with SGRQ-C.
