The Global Adult Tobacco Survey is a nationally representative household-based survey for adults aged 15 years old and over. GATS is developed to systematically monitor tobacco use (smoked and smokeless) and track key tobacco control interventions in the country. The GATS has been implemented in middle-low-income countries to fulfill obligations under the WHO Framework Convention on Tobacco Control (FCTC) and the MPOWER package of tobacco policies as key to the FCTC. The MPOWER policies are: Monitor tobacco use and prevention policies; Protect people from tobacco smoke; Offer help to quit tobacco use; Warn about the dangers of tobacco; Enforce bans on tobacco advertising, promotion, and sponsorship; and Raise taxes on tobacco.
