AB  - There is little information on the prevalence of COPD among people with other chronic conditions. We determined the cross sectional prevalence of COPD among Canadians with diabetes, asthma, hypertension, and mood/anxiety disorders. We also compared the all-cause mortality between individuals with these other diseases with/without COPD.Methods: Using the Canadian Chronic Disease Surveillance System (CCDSS), we analyzed 2008/2009 administrative health data for Canadians aged 35 years and older, from 12 of 13 provinces/territories. COPD, diabetes, hypertension, mood/anxiety disorders and asthma were identified using ICD9/10 codes from physician billing and hospitalization records. Results: The prevalence of COPD among Canadians aged 35 years and older was 8.2%. The prevalence of COPD among people with diabetes, hypertension, mood/anxiety disorder and asthma was respectively 11.4% (95% confidence interval (CI) 11.35, 11.44), 10.0% (95%CI 9.99, 10.04), 11.6%, (95%CI 11.57, 11.66) and 26.3% (95%CI 26.20, 26.35). In addition, a diagnosis of COPD was associated with a 140% increase in mortality among people with diabetes and a 154% increase in mortality among people with hypertension (comorbid mortality among people with asthma or mood/anxiety disorders could not be calculated because the data were not available).Conclusions: COPD is a prevalent comorbid condition for individuals with asthma, mood/anxiety disorder, diabetes and hypertension and comorbid COPD is associated with higher mortality. An integrated care approach to these patients may optimize health outcomes and reduce the burden of chronic disease.
