title: Depressed mood predicts pulmonary rehabilitation completion among women, but not men.
abstract: BACKGROUND
  As many as 30% of patients who start pulmonary rehabilitation (PR) fail to complete it, and depressed mood has been associated with PR non-completion. Depression is more common in women than men with COPD and historically women with COPD have been under studied. However, no studies to date have investigated gender-specific predictors of PR completion.
  
  
  METHODS
  The study included 111 patients with COPD who enrolled in a community based outpatient PR program in Providence, RI. Patients who attended 20 or more sessions were designated "completers". Depression was measured using the CES-D. Logistic regression models were evaluated to test depressed mood as a predictor of PR completion. Analyses controlled for demographic and health variables found to differ between completers and non-completers.
  
  
  RESULTS
  Patients were 95% white and 49.5% women, and 74% had a GOLD stage ≥3. Sixty-eight percent of patients were PR completers. A logistic regression model, showed that lower depressed mood independently predicted PR completion across all patients (adjusted OR = 0.92, p = .002). In gender-stratified analyses, lower depressed mood was an independent predictor of PR completion for women (adjusted OR = .91, p = .024) but not men (adjusted OR = .97, p = .45). Greater 6-min walk test distance was also an independent predictor of PR completion among women.
  
  
  CONCLUSIONS
  Depressed mood is an important predictor of completion of community based PR among women. Screening and brief treatment of depression should be considered in practice.
