The publication conveys the quantitative surveillance results focusing on tobacco use and noncommunicable disease (NCD) related behaviours among youth (13–15 years) in Member States of the WHO South-East Asia Region, namely, the Global School-based Student Health Survey (GSHS) and the Global Youth Tobacco Survey (GYTS). This publication contains selected indicators relating to tobacco use and other related risk behaviours of youth (aged 13–15 years) in Member States of the WHO South-East Asia Region. The tobacco indicators are mainly taken from GYTS and other indicators relating to risk behaviours (dietary behaviours, physical activity, alcohol use, drug use, mental health, violence and unintentional injury, sexual behaviours, protective factors and hygiene) are taken from GSHS. The latest findings from surveys conducted in Member States are presented in the publication.
