Relationship Between Depression in Patients With COPD and the Percent of Predicted FEV ₁ , BODE Index, and Health-Related Quality of Life

We found a high prevalence of depression among patients with stable COPD treated in long-term in-patient rehabilitation facilities. Depression among these patients, as measured by the CES-D, was associated with greater impairment in respiratory function and with poorer Modified Medical Research Council dyspnea scale and SGRQ scores. The prevalence of depression increased with BODE stage.
