Methods This study examined data from adult respondents (aged ≥18 years) in the National Survey on Drug Use and Health, an annual cross-sectional study of U.S. individuals. Data from the years 2005 to 2014 were analyzed for a total analytic sample of n =378,733. The prevalence of past-month cigarette smoking was examined annually from 2005 to 2014 among adults with and without past-year major depression, overall and by income/education, using linear trend analyses. Data analysis occurred in 2017. Results The prevalence of smoking declined significantly from 2005 to 2014 among those with depression (37.62% to 34.01%; p p Conclusions Disparities in smoking prevalence are pronounced when depression and SES are considered simultaneously. Targeted public health and clinical efforts to reduce smoking among adult smokers of lower SES with depression are needed.
