ABSTRACT
This study is designed to evaluate the prevalence of waterpipe tobacco smoking and its related factors among Iranian adults. This is a cross-sectional study carried out during 2013/14 in Tehran, Islamic Republic of Iran, among 1830 citizens aged over 15 years. Sampling was through Stratified multistage cluster sampling with proportional allocation within strata. Global Adult Tobacco Survey [GATS] questionnaire for waterpipe consumption was used for data gathering. Data were statistically analyzed by SPSS software. The prevalence of current waterpipe tobacco smoking was 17.6% .Waterpipe use prevalence in men was significantly more than women [24.2% vs. 11.3%]. Multivariate analysis showed that age, sex, cigarette consumption, waterpipe consumption at home and ignorance of safety issues significantly influenced current waterpipe smoking [P = 0.001]. Thus, prevalence of waterpipe smoking in Iranian adults is high and significant. Tackling waterpipe smoking should be considered in tobacco control programmes. However, further studies in this field are needed
