A data analysis was conducted of 106 subjects who complete a questionnaire and have taken a pulmonary function test in 3 years recently. 

Results
By ANOVA of the CES-D scores, moderate group were significantly increased from 18.08 to 24.91 than mild group (p< 0.05). In logistic regression analyses, after adjusted for age, smoking status, marital status, education level, daily activities (OR=2.18, 95%CI=1.13-4.21) and social activities (OR=2.72, 95%CI=1.38-5.37) were the significant factors associated with poor health-related quality of life among pulmonary dysfunction groups. 

Discussion
