Trends in cigarette smoking prevalence and status among US adults with disabilities, 2015-2019

Introduction: The prevalence of current cigarette smoking is higher in people with disabilities compared to those without. However, little is known about smoking status and trends in smoking by disability functioning domain.Methods: Data from the 2015-2019 National Surveys on Drug Use and Health were used to estimate the prev-alence of past-month and daily cigarette smoking, former smoking, and nicotine dependence for people with any disability and six disability functioning domains. Logistic regression models estimated the odds of each outcome by disability domain compared to no disability, adjusting for sociodemographic factors.Results: From 2015-2019, the overall prevalence of current cigarette smoking (23.3% vs. 16.7%) and the pro-portion of those with nicotine dependence (14.6% vs 8.0%) was higher in people with any disability compared to those without (ps < 0.001). The prevalence of current cigarette smoking decreased while the prevalence of former cigarette smoking increased from 2015 to 2019 (ps < 0.05). People with any disability had higher odds of current smoking (AOR=1.20; 95% CI 1.16, 1.25) and similar odds of former smoking (AOR=1.00; 95% CI 0.95, 1.06) compared to people without disabilities. Odds of current and former smoking varied by domain.Conclusion: The prevalence of cigarette smoking among people with any disability decreased over time but remained higher than those without. People with any disability had similar odds of former smoking, though differences existed by disability domain. Future research should explore additional smoking and quit behaviors by disability functioning domain.
