Introduction: Public health interventions have heightened awareness of risk factors and ill effects of tobacco use. Though sales of conventional tobacco products have steadily been declining, there is the advent of a new generation of alternative tobacco products that are being marketed with claims of reduced harms and smoking cessation aid.

Aim: The aim of this study is to assess the prevalence of tobacco quit attempt among U.S. adolescents and to examine its relationship to the use and self-reported awareness of two alternative tobacco products (E-cigarettes and Heated Tobacco Products).

Methods: This is a cross-sectional analysis of data (2,271) from the 2019 National Youth Tobacco Survey (NYTS) of middle and high school students in the U.S. Logistic regression analysis was employed to determine the odds of tobacco quit attempt adjusting for age, race, gender, school type, and household tobacco exposure.

Results: The overall prevalence of tobacco quit attempt among e-cigarette users and HTP users was 52.50% and 5.20%, respectively. Results of multivariate regression analyses identified age (OR=0.74, 95% CI:0.57-0.96), race (OR=1.41, 95% CI:1.14-1.75), and household tobacco smoke exposure (OR=1.19, 95% CI:1.01-1.39) as the main factors that are significantly associated with tobacco quit attempt adjusting for all other covariates.

Conclusion: The results of this study did not show a statistically significant association between the awareness and use of e-cigarettes and heated tobacco products and tobacco smoking quit attempt. Race, age, and exposure to household tobacco smoking were found to be positively associated with quit attempts. Further studies are needed to clarify whether the use and awareness of e-cigarette and HTPs are associated with smoking quit attempt.
