Second-hand tobacco smoke (SHS) exposure at home, especially among children, is a serious issue in Viet
Nam. During the past decade, much effort has been taken for tobacco control in the country, including various
prgorammes aiming to reduce SHS exposure among adults and children. This article analysed trends and
factors associated with SHS exposure at home among school children aged 13-15 in Viet Nam, using the Global
Youth Tobacco Surveys conducted in 2007 and 2014. Descriptive and inferential statistical methods with logistic
regression were applied. Overall, there was a significant reduction in the level of exposure, from 58.5% (95%CI:
57.6-59.3) in 2007 to 47.1% (95%CI: 45.4-48.8) in 2014. Of the associated factors, having one or both parents
smoking was significantly associated with the highest odds of SHS exposure at home (OR=5.0; 95%CI: 4.2-6.1).
Conversely, having a mother with a college or higher education level was found to be a protective factor (OR=0.5;
95%CI: 0.3-0.8).
