Abstract
OBJECTIVE: Today, smoking is considered a pressing global health issue. The present study aimed to estimate the total prevalence of hookah smoking among pupils and university students in Iran. MATERIALS AND METHODS: This systematic review and meta-analysis were conducted via searching in databases such as Scientific Information Database (SID), MagIran, Scopus, PubMed and Web of Sciences from inception to October 2021. We targeted observational studies evaluating the prevalence or frequency of hookah smoking among Iranian pupils and university students. Data analysis was performed using a random-effects model, and the heterogeneity of the articles was assessed using Cochran's Q test and the I(2) statistic. RESULTS: In total, 124 studies conducted on 155 115 subjects were reviewed. The lifetime prevalence of hookah smoking among high school students and university students was estimated at 34.4% and 32.3%, respectively. In addition, the frequency of hookah smoking within the past month/week (point prevalence) was estimated at 21.5% and 16.6% in university students and pupils, respectively. The frequency of hookah smoking within the past year (period prevalence) was also reported to be 22.5% and 20.8% in these groups, respectively. No significant correlation was observed between the prevalence of hookah smoking, sample size, year of publication and the mean age of the participants. Region 5 had the highest lifetime prevalence (41.7%) and period prevalence (27.1%). However, Region 1 had the highest point prevalence of hookah smoking (27.2%). CONCLUSIONS: According to the results, hookah smoking is highly prevalent among Iranian pupils and university students. Therefore, proper educational interventions are required in the form of workshops and curricula to raise awareness regarding the hazardous effects of this unhealthy habit on the young generation.
