COPD Rates Reflect Current Smoking Prevalence

Key clinical point: State-wide patterns of chronic obstructive pulmonary disease prevalence were similar among smokers, former smokers, and nonsmokers.

Major finding: State-level chronic obstructive pulmonary disease prevalence among those who never smoked (Pearson correlation coefficient, 0.64; P less than .001) was strongly correlated with state-level current smoking prevalence.

Study details: An analysis of 418,378 U.S. adult respondents to the 2017 Behavioral Risk Factor Surveillance System survey.
