Abstract

Background: Smoking is known as the most important preventable risk factor for morbidity and premature death. It is the fourth risk factor attributable to burden of disease globally. Because of the misconception that waterpipe is less harmless than cigarette and also less socially prohibited, people smoke waterpipe more. Studies showed that tobacco consumption rate is increasing among adolescents and it`s initiation age has been declined. The aim of current study was the assessment of the prevalence of different types of tobacco use among students aged between 14 to 18 year old in Tehran. Also we had a comparison with similar studies. Methods: In this cross-sectional study 2877 students between May and July 2014 have been assessed. Samples were collected from language institutes and “Farhangsara”s according to stratified cluster sampling based on the educational zones in Tehran. A structured questionnaire was used for different types of tobacco use habit assessment. Because of sampling method, data analysis was done with complex sample survey analysis in SPSS, ver. 20 (Chicago, IL, USA) and Stata, ver. 12 (College Station, TX, USA) software. P-values less than 0.05 considered as statistically significance. Results: Among participants 11.5% (10.8%-13.3%) had cigarette smoking experience. The prevalence of current cigarette smoking was 4.4% (3.7%-5.3%). 1.4% (0.9%-2.2%) of girls and 7% (5.7%-8.5%) of boys were current cigarette smokers (P< 0.001). Waterpipe smoking experience prevalence was 41.5% (39.7%-43.4%) in total, 41.7% (39.2%-44.2%) in girls and 41.4% (39.2%-44.2%) in boys. Current waterpipe smoking was reported in 25.7% (24.1%-27.4%) of students with no statistically significant difference between boys and girls. Pipe smoking experience prevalence was 3.9% (3.2%4.7%) and it was more frequent in boys. Conclusion: Cigarette smoking was significantly higher among boys than girls, while waterpipe smoking prevalence showed no difference. In addition, smoking prevalence was higher among students who had smoker parents or smoker friends and also had a bad economic status. It seems that specific interventions should be considered to reduce tobacco burden in adolescents specially in regard to cigarette and waterpipe smoking. © 2015 Tehran University of Medical Sciences.
