Background & Objectives: Tobacco smoking is known to cause a huge burden of disease throughout the world: smoking is responsible for 4 million deaths per year. This study is performed in order to fill the existing gaps in information regarding current trends for lifestyle and tobacco-related disease in Iran.
Methods: This was a cross-sectional study performed with the help of a questionnaire and using a multi-stage cluster sampling method. The final sample size, after the screening of the data, was 84706 out of 89457 records.

The prevalence of smoking was higher in people aged 35 to 64 years (P<0.001). Quitting rates increased with age, especially in women (P<0.001). Smoking was more prevalent in men (P<0.001) and in rural areas (P<0.001). The average number of cigarettes smoked per day was 14.69. Smoking prevalence was lower among adults with higher levels of education compared to those with lower education levels (P<0.001).
Conclusions: This nationwide survey provides a baseline for future longitudinal studies of smoking in Iran. There is a need for effective smoking prevention and cessation programs with a focus on the young population.
