Stagnant daily smoking prevalence between 2008 and 2019 among Black and Hispanic adults with serious psychological distress.

BACKGROUND: Racial/ethnic minority status and mental illness independently drive inequity in cigarette smoking and related morbidity. Racial/ethnic minority groups suffer a disproportionate burden of tobacco-related diseases. People with serious mental illness (SMI) smoke at up to 7 times the rate of the general population. There is a need to quantify smoking prevalence and trends among people at the intersection of both groups.

METHODS: This study analyzes 2008-2019 data from the National Survey on Drug Use and Health. Linear time trends of daily smoking prevalence were assessed among people with serious psychological distress (SPD; marker for SMI) and people without SPD reporting White, Black, Hispanic, and Other race/ethnicity using logistic regression, with survey year as the predictor. Models with year-by-smoking status interaction terms and F-tests assessed differential time trends.

RESULTS: The prevalence of daily smoking among people without SPD decreased over time among people reporting White (aOR=0.96, p<0.001), Black (aOR=0.96, p<0.001), Hispanic (aOR=0.95, p<0.001), and Other (aOR=0.97, p=0.002) race/ethnicity. Among people with SPD, the smoking prevalence decreased among people with White race/ethnicity (aOR=0.95, p<0.001), with no significant changes among people of Black, Hispanic, and Other race/ethnicity.

CONCLUSIONS: Smoking among people with SPD who report Black and Hispanic race/ethnicity has not changed significantly in the past 11 years, despite decreasing among non-SPD and White groups. People who are Black/Hispanic and people with SPD struggle to quit smoking, which is amplified intersectionally. Tailored interventions may be a better mechanism to reduce barriers to smoking cessation in this population.
