Background Adolescent tobacco use (ATU) is a global public health concern, causing significant morbidity and premature death. This study aimed to assess trends in the prevalence of ATU in Indonesia between 2009 and 2019 and to identify factors contributing to the observed changes. Methods This study performed secondary data analysis of three consecutive waves (2009, 2014, and 2019) of the Indonesian Global Youth Tobacco Survey (IGYTS). Weighted prevalence estimates and complex survey data analysed using multivariate logistic regression were established across the three-wave surveys. A pooled IGYTS data set was explored to determine the risk factors of the ATU. A multivariate decomposition analysis (MDA) was used to determine factors contributing to the prevalence change in male adolescents over the last two surveys. Results The prevalence of ATUs was 21.1% (38.2% in males; 6.4% in females), 18.6% (32.7% in males; 3.9% in females) and 19.8% (36.8% in males; 3.5% in females) for the three consecutive surveys, respectively. Being older adolescents, male, exposed to SHS (secondhand smoke) at home, tobacco industry promotion, not knowledgeable of the dangers of tobacco smoke and SHS, and against banning smoking in public places were associated with ATU consistently across the surveys. In addition, inadequate anti-cigarette media and not being knowledgeable of the difficulty of quitting smoking were also identified as risk factors in the pooled data. MDA showed that 88.94% of the explained change was due to differences in the composition of explanatory variables between the last two surveys. Conclusions This study suggests that social influence and tobacco industry promotion significantly impact ATU in Indonesia. Governments should emphasise these factors in their tobacco control interventions.
