Three-month effects of Project EX: A smoking intervention pilot program with Thai adolescents

Adolescent smoking is a major public health problem around the world, including Thailand. The current study provides a three-month follow-up evaluation of the Project EX tobacco use cessation program among Thai adolescents. The intervention was tested involving a quasi-experimental trial with 185 smokers, with two program and two control condition schools (within each condition, one school in Bangkok Province and one school in Nakhon Pathom Province). At 3-month follow-up, the intent-to-treat (ITT) quit rate was 23% in the program group and 11% in the standard care control group (p < 0.02). The intervention also lowered the level of last 30-day smoking at follow-up among persons who did not quit in the program condition, while no change in level of smoking was reported in the control condition. These results are promising for teen tobacco use cessation programming in Thailand.
