Tobacco use among thai students: Results from the 2015 global youth tobacco survey.

Background: Tobacco use often starts in adolescence and is a leading cause of premature mortality. Two previous rounds of the global youth tobacco survey (GYTS) found that a significant proportion of Thai youth currently smoke.

Objectives: We conducted the third round of GYTS in Thailand in 2015 to monitor trends in tobacco use.

Methods: We selected 31 public and private secondary schools using random sampling based on probability proportional to school enrolment. In each school, we selected 1-3 classes (Grades 7-9) by random sampling. All students in these classes from 30 schools (one school declined) completed a self-administered standard questionnaire in the Thai language. The association between tobacco use and independent variables was examined using univariate and multivariable logistic regression analysis.

Results: Of 1876 students, 1721 were aged 13-15 years. Overall, 15% of students currently used tobacco; boys 21.8% and girls 8.1%. The prevalence of current cigarette smoking was 11.3%; 3.3% students currently used electronic cigarettes. Exposure to secondhand smoke (SHS) at home, school, and in enclosed public places was reported by 33.8%, 47.9%, and 38.6%, respectively. Among current smokers, 44% were not stopped from purchasing cigarettes despite being underage. Higher tobacco use was associated with being older, male, exposed to SHS, in possession of an object with a tobacco logo, and being offered a free tobacco product by a tobacco company.

Conclusion: Tobacco and cigarette use among Thai students remains high. Underage current smokers have easy access to cigarettes. Urgent steps are needed to curb the access of youth to tobacco.
