Abstract
BACKGROUND: The International Depression Epidemiological Study (TIDES) found elevated rates of screen positivity for depression and anxiety among individuals with cystic fibrosis (CF). Depression is associated with worse adherence and health-related quality of life in CF. We investigated the relationship with mortality. METHODS: Subjects were untransplanted participants in TIDES 12+ years of age receiving care at one of 45 collaborating US CF care centers who completed the Hospital Anxiety and Depression Scale and/or Center for Epidemiologic Studies Depression Scale during a stable visit between 2006 and 2010. Clinical characteristics and mortality data were obtained from the CF Foundation Patient Registry. The association of a positive screen with 5-year survival was evaluated using Cox Proportional Hazards modeling. RESULTS: Of 1005 eligible patients, 25% screened positive for depression and 34% screened positive for anxiety. Patients who screened positive for depression were more likely to be older, have a residual function mutation, public insurance, and more pulmonary exacerbations in the screening year. There were 96 deaths. The unadjusted 5-year Hazard Ratio (HR) for death among those with depression was 2.0; 95% CI (1.3, 3.0)]. When adjusted for predetermined potential confounders the HR for the entire population was 1.4; 95% CI (0.9, 2.2). The adjusted HR was higher in adults [1.6; 95% CI (1.0, 2.4)] and those screening in the severe range [2.0; 95% CI (1.2, 3.4)]. Anxiety was not associated with mortality. CONCLUSIONS: A positive depression screen is associated with increased mortality among adults with CF. Research into the etiology of this relationship is needed.
