Abstract

Study objectiveTo describe factors associated with COPD deaths in the United States.DesignCross-sectional survey.ParticipantsA total of 12,803 decedents in the National Mortality Followback Survey, a nationally representative sample of US deaths in 1993.MethodsWe compared the characteristics of adults ≥ 35 years of age who died with COPD (bronchitis, emphysema, chronic airway obstruction) with those dying without COPD listed on their death certificates.ResultsOf the estimated 225,400 adults who died with COPD in 1993, 16.7% had never smoked. People dying with COPD were more likely than those dying without COPD to be current smokers (odds ratio [OR], 6.5; 95% confidence interval [CI], 4.3 to 9.9) or former smokers (OR, 3.7; 95% CI, 2.5 to 5.3), have a history of asthma (OR, 5.0; 95% CI, 3.2 to 7.8), be underweight (OR, 4.5; 95% CI, 2.8 to 7.2), and be of the white race (OR, 3.1; 95% CI, 2.4 to 4.0), after controlling for age group and sex.ConclusionsA significant proportion of COPD-related deaths occurs in never-smokers. Factors such as a history of asthma and being underweight are associated with COPD mortality and may provide additional opportunities for intervention.
