Smoking is known as a major cause of chronic obstructive pulmonary disease (COPD) and hence
immediate and effective interventions are required for its elimination. This study aimed to collect valid data
with regard to cigarette smoking in adult population of north of Iran for policy making by a meta-analysis of
the documents of national non-communicable disease risk factors surveillance system. We investigated
relevant evidences by searching in published and non-electronic databases. Data were extracted based on
variables such as year of the study, sex, age group and prevalence of smoking habit. Based on results of
heterogeneity, we applied fixed or random effects model to estimate the overall prevalence of cigarette
smoking. All analyses were performed using STATA 11 software. A total of 20747 subjects (10381 males
and 10366 females) in five age groups 15-24, 25-34, 35-44, 45-54 and 55-64 years were interviewed. Metaanalysis
in men and women showed prevalence of 19.2% (15.8-22.6%) and 0.3% (0.2-0.5%) respectively.
Results of the present meta-analysis showed as much as one fifth of male population of north of Iran are
smoker. Subgroup analysis also revealed that the rate of smoking was higher among the middle-aged men.
