Cigarette Smoking among Adolescents aged 13-15 in Viet Nam and Correlates of Current Cigarette Smoking: Results from GYTS 2014 Data


Institute of Preventive Medicine and Public Health, Hanoi Medical University, Viet Nam


The aim of this paper is to report the rate of current and ever cigarette smoking and explore correlates of
current cigarette smoking among adolescents aged 13-15 in Viet Nam. This analysis was derived from GYTS
survey, which comprised of 3,430 adolescents aged 13-15, conducted in 2014 in 13 cities and provinces of Viet
Nam. We calculated the weighted rates of current and ever cigarette smoking and reported patterns of smoking
behavior. We also performed logistic regression to explore correlates of current cigarette smoking behavior. The
weighted rate of ever cigarette smoking was 9.5% (95% confidence interval (CI): 8.5 %-10.5%), in which the
weighted rate among males (15.4%; 95% CI: 13.6%-17.0%) was higher than that among females (4.2%; 95%
CI: 3.3%-5.1%). The weighted rate of current cigarette smoking was relatively low at 2.5% (95%CI: 2.0%-
3.0%) with higher weighted rate among males (4.9%; 95% CI: 3.8%-5.9%) compared to the corresponding
figure among females (0.2%; 95% CI: 0.0 %-0.5%). Current cigarette smoking was significantly higher among
males than females, in students aged 15 versus 13 years old, and in students who had several or all close friends
smoking and students with daily observation of smoking at school. For greater smoking reduction outcomes, we
recommend that tobacco interventions for adolescents should consider targeting more male students at older
ages, establish stricter adherence to school-based banning of cigarette smoking, engage both smoking and nonsmoking
adolescents and empower adolescents to resist peer smoking influence as well as changing their norms
or beliefs towards smoking benefits.
