Smoking prevalence and cessation characteristics among U.S. adults with and without COPD: findings from the 2011 Behavioral Risk Factor Surveillance System.
BACKGROUND
Cigarette smoking is a major cause of chronic obstructive pulmonary disease, (COPD) but many persons with COPD continue to smoke. Quitting can help prevent the development of and complications from COPD. This study examined whether smoking and cessation behaviors differed among adults with a) COPD, b) asthma, c) other chronic conditions only, or d) no chronic conditions.


METHODS
Smoking and chronic disease status was obtained from 488,909 adults aged > 18 years using the Behavioral Risk Factor Surveillance System; 9,476 current smokers and recent quitters in 5 states responded to additional questions about cessation. We computed age-adjusted prevalence of smoking and past-year quit attempts, and used bivariate and multivariable logistic regression to identify correlates of past-year quit attempts.


RESULTS
Similar to the overall sample, in the 5-state sample, 47.3% of adults with COPD were current smokers versus 23.1% of those with asthma, 28.8% of adults with other chronic conditions, and 20.0% of those with no chronic conditions. Those with COPD did not differ significantly from those with asthma, other chronic diseases, or no chronic disease in having made a past-year quit attempt (59.7% versus 64.0%, 61.5%, and 53.9%, respectively). Smokers with COPD were significantly more likely than those with no chronic disease to have used cessation treatment resources, including a quitline, counseling, or medication (p < 0.001).


CONCLUSIONS
Adults with COPD were just as likely as those without COPD to make a past-year quit attempt; however, approximately 40% of smokers with COPD did not try to quit.
