, according to a Centers for Disease Control and Prevention analysis of respondents to a behavioral risk factor survey.
“Population-based strategies for smoking prevention and control have the potential to decrease the prevalence of COPD in the United States,” wrote Anne G. Wheaton, PhD, of the CDC’s National Center for Chronic Disease Prevention and Health Promotion and coauthors. The study was published in the Morbidity and Mortality Weekly Report.
Dr. Wheaton and her fellow researchers analyzed data from 418,378 adult respondents to the 2017 Behavioral Risk Factor Surveillance System survey. Responses came from all 50 states and Washington, D.C.; respondents who had smoked less than 100 lifetime cigarettes were categorized as “never smoked,” while those who had smoked at least 100 cigarettes but no longer smoked were categorized as “former smokers.” Anyone who had smoked at least 100 cigarettes and currently smoked was categorized as a “current smoker.”
The age-adjusted prevalence of COPD among U.S. adults was 6.2% (95% confidence interval, 6.0%-6.3%) in 2017. Current cigarette smokers had a prevalence of 15.2% (95% CI, 14.7%-15.7%); this dipped to 7.6% (95% CI, 7.3%-8.0%) among former smokers and 2.8% (95% CI, 2.7%-2.9%) among adults who had never smoked. Patterns were visible within states: Current smokers had a state-level prevalence of COPD that was strongly correlated with state-level current smoking prevalence (Pearson correlation coefficient, 0.69; P less than .001). State-level COPD prevalence among former smokers (Pearson correlation coefficient, 0.71; P less than .001) and those who never smoked (Pearson correlation coefficient, 0.64; P less than .001) were also strongly correlated with the current smoking prevalence, indicating secondhand smoke as a risk factor for COPD.
The coauthors acknowledged the study’s limitations, including relying on self-reporting for both COPD and smoking status. They also noted that there was no way to measure exposure to secondhand smoke, other indoor or outdoor air pollutants, or respiratory infection history, “all of which might contribute to COPD risk.”
No conflicts of interest were reported.
