ABSTRACT
Symptoms of anxiety and depression have important consequences for patients with chronic
disease, including lower rates of adherence and increased morbidity. This review discusses
the prevalence of anxiety and depression in patients with cystic fibrosis (CF) across
the life span and highlights current understanding of how these symptoms affect adherence,
health outcomes, and health-related quality of life (HRQOL). Anxiety and depression
appear to be more common in patients with CF than in the general population. Recent
studies also indicate that symptoms of anxiety occur more frequently than depression
in this population. Both anxiety and depression have been shown to be associated with
poorer disease outcomes, including HRQOL. Depression, specifically, leads to lower
adherence to recommended therapies. Given the prevalence and impact of anxiety and
depression in CF, it seems appropriate to recommend annual screening using a validated
approach, with referral for either pharmacotherapy or cognitive behavioral therapy
of those with apparent symptoms. A large-scale epidemiological study of anxiety and
depression in CF is under way and should provide better prevalence estimates and more
information on the effects of these psychological symptoms.
