AB Comorbidities are common among subjects with COPD, and most probably contribute to the increased mortality observed among subjects with COPD. The association between different comorbidities and mortality is rarely studied.Aim: To evaluate the impact of common comorbidities; heart disease (HD), diabetes mellitus (DM) and anxiety/depression (A/D), on mortality in a population based study of subject with and without airway obstruction.Methods: The OLIN COPD study was recruited from population based studies in 2002-04 including spirometry and structured interview. All 993 subjects with airway obstruction, FEV1/(F)VC<0.70, were identified together with age- and sex matched referents without airway obstruction. Mortality data was collected until December 2015.Results: The cumulative mortality was significantly higher among subjects with than without airway obstruction, 37.9% vs. 29.2% (p<0.001). In a multivariate model, airway obstruction increased the risk for death also when adjusted for age, sex and smoking habits, HR 1.21 (95%CI 1.03-1.43). HD, DM and A/D were analysed as risk factors for death, HR (95%CI), in a model adjusting for sex, age and smoking habits; among subjects with airway obstruction 1.19(0.91–1.56), 1.51(1.10– 2.08) and 1.45(1.04– 2.02), and among non-obstructive 1.32(1.05–1.67), 1.40(1.04-1.87) and 1.38 (1.08–1.77).Conclusion: Heart disease, diabetes mellitus and anxiety/depression increased the risk for death independently of each other both among subjects with and without airway obstruction, even though heart disease did not reach significance as a risk factor for death among those with airway obstruction.
