Multiple anti-smoking messages are linked to ~149% higher odds of adolescent smoking cessation.
Cross-Sectional (n=454)
Yes
Effect estimate: OR 2.48 for cessation with one smoking parent vs no parent smoking; OR 2.23 for highest tobacco knowledge score vs lowest; OR 2.49 for exposure to two or more anti-smoking sources vs none; OR 0.31 for having smoking friends vs none (95% CI 95% CI: 1.39–4.43 (one parent smoking), 1.30–3.83 (knowledge), 1.05–5.92 (anti-smoking exposure), 0.14–0.69 (peer smoking))
Absolute Event Rate: 76.9% vs 23.1%
p-value: p=<0.05 for all above associations
Economic status, peer influence, parental smoking, and cognitive factors are key determinants of smoking cessation among Vietnamese adolescents, highlighting the need for comprehensive, gender-sensitive tobacco control programs.
Economic status, peer influence, parental smoking, and cognitive factors namely tobacco-related knowledge and exposure to anti-smoking information were key determinants of smoking cessation among Vietnamese adolescents, with notable gender differences. These findings suggest the need for comprehensive tobacco control programs that address these factors to more effectively reduce smoking rates among this population.

Lai et al. (2026) conducted a cross-sectional in Vietnamese adolescents aged 13-15 years who have ever tried smoking any smoked tobacco product (n=454). Among Vietnamese adolescents aged 13-15 who tried smoking, 76.9% had quit smoking, with cessation odds higher for those with one smoking parent (OR 2.48), greater tobacco knowledge (OR 2.23), and exposure to multiple anti-smoking messages (OR 2.49), while peer smoking reduced cessation likelihood (OR 0.31).
