This study aimed to determine if there are racial disparities in smoking cessation among stroke survivors. 

Black Americans face a higher risk of recurrent stroke than White Americans, and the reasons are unclear. Smoking after stroke is associated with higher recurrent stroke risk. Disparities in smoking cessation may contribute to differences in recurrent stroke. 

We performed a cross-sectional analysis of data from the Centers for Disease Control and Prevention Behavioral Risk Factor Surveillance System, a nationally representative health survey. Data was pooled from 2013-2018, during which race and ethnicity were uniformly reported. Respondents with prior stroke and any smoking history were included. The exposure was self-reported race, and the outcome was smoking cessation. We calculated the quit ratio, conventionally defined as the proportion of former smokers among ever smokers. Survey procedures were used to estimate frequencies and summarize quit ratios by race. Multiple logistic regression was used to assess the association of Black race with smoking cessation, as compared to White race, while adjusting for age, gender, Hispanic ethnicity, education, income, health insurance, and smoking-related comorbidities.  
Among 4,374,011 Americans with a history of stroke and any smoking, the median age was 67 years (IQR, 58-76), and 45.7% were women; 15.4% were Black, 74.8% were White, and 9.8% reported other race. The crude quit ratio was 51.4% (95% CI, 49.0-53.7) in Black and 63.2% (95% CI, 62.4-64.1) in White stroke survivors. In unadjusted analyses, Black stroke survivors were less likely to have quit smoking than White stroke survivors (OR, 0.61; 95% CI, 0.55-0.68). This remained the case after accounting for demographics and smoking-related comorbidities (OR, 0.85; 95% CI, 0.74-0.98). 

In this nationwide study, Black stroke survivors had lower smoking quit rates than White stroke survivors, even after accounting for group differences. Expanding access to smoking-cessation interventions may reduce recurrent stroke disparities.
