Association between tobacco advertising policies, health warning mandates and adolescents' exposure to tobacco advertising and warning labels in 80 countries.

Background: Implementation of tobacco advertising, promotion and sponsorship (TAPS) bans and of health warning mandates varies by country, and their impact on adolescents' exposure to tobacco-related messages is not well understood, particularly in low-income and middle-income countries.

Aim: To explore the association of the implementation of TAPS bans and health warning mandates with the proportion of adolescents exposed to tobacco advertisements and health warnings in 80 countries from 2016 to 2021.

Methods: The proportion of 11-17 years old exposed to tobacco advertising was assessed using Global Youth Tobacco Survey data (80 countries, n=428 347).
