Quality of life and its related factors in patients of stable chronic obstructive pulmonary disease

A total of 185 hospitalized patients with chronic obstructive pulmonary disease (COPD) were recruited.And the questionnaire of COPD Assessment Test (CAT) was used to evaluate the CAT scores and Hamihon Depression Scale to evaluate HAMD scores.Lung function,body mass index,smoking and medication were measured and recorded in details.According to the HAMD scores,65 cases had depression and 120 cases no depression.Comparing with the no-depression group,the results show that HAMD and CAT scores were higher significantly in the depression group and there was a lower proportion of long-term domiciliary oxygen therapy.According to the logistic regression analysis,the CAT scores were associated with global initiative for chronic obstructive lung disease (GOLD) stages Ⅳ and HAMD scores.These results suggest that poor lung function and depression affect greatly the quality of life for stable COPD patients.
