Background: Theory-based tobacco use prevention programs in schools were implemented to evaluate the effectiveness of this peer-led intervention on tobacco use-related knowledge, attitude, normative beliefs, and intention to tobacco use of school children aged 14–17 years old. Methods: A school-based cluster randomized controlled intervention study was conducted among 1st, 2nd, and 3rd grade high school children in Sanandaj City, Iran. 4-h integrated tobacco use prevention program comprising of four structured modules was developed and delivered to the intervention group by trained peer educator. Outcome measures comprised changes in students' smoking-related knowledge, attitude, normative beliefs, and intention to tobacco use from baseline to 6-month follow-up through validated anonymous questionnaire. Results: The present study showed an intervention effect on tobacco use-related knowledge, normative beliefs, and intention to tobacco use but not attitude. The results indicated that there was significant decrease in intention to tobacco use (P ≤ 0.013) observed after 6-month postintervention. The intervention module was also effective in improving smoking knowledge (P ≤ 0.001), normative beliefs with regard to perceived prevalence of cigarette smoking and water-pipe use among adults and adolescents (P ≤ 0.001) in intervention group 6-month postintervention. Conclusions: Participation in the peer-led education program to tobacco use prevention may have improvement in knowledge, normative beliefs, and intention to tobacco use. An implementation of the peer-led behavioral intervention components in the school setting may have a beneficial effect on public health by decreasing intention to tobacco use among nonsmoker adolescents.
