A systematic review of the prevalence and risk factors of smoking among Saudi adolescents

Objectives: To systemically review the evidence concerning the prevalence and reported risk factors of smoking among adolescents in Saudi Arabia.
Methods: Following the PRISMA guidelines, studies that examined the prevalence and risk factors of smoking among adolescents in Saudi Arabia were identified through a computerized literature search using the following databases up to March 2018: PubMed, SCOPUS, Web of Science, and BIOSIS. The following search terms were used: smoking OR smok* OR tobacco OR cigar* OR shisha OR shesha OR sheesha AND Saudi Arabia OR KSA. Peer-reviewed articles published within the period from 2007 to 2018 were selected. Studies that reported prevalence data, patterns, and risk factors of smoking among adolescents were included. Extracted data from each study were tabulated, and data were narratively synthesized.
Results: Thirty-two studies that reported the prevalence of smoking in the adolescent age group were included in the narrative evidence synthesis. These studies were conducted on secondary school students (n=11), college students (n=14), and an adolescent age group without educational specifications (n=7). According to published reports between 2007 and 2018, the prevalence of tobacco smoking among adolescents in Saudi Arabia ranged from 2.4% to 39.6%. Influence of friends, and family negligence were the most commonly reported risk factors for smoking.
Conclusion: The prevalence of smoking is relatively high among adolescents in Saudi Arabia. The social influence of friends, teachers or parents, low academic performance, having spare time, living away from home, and the desire to relieve stress were the most commonly reported risk factors for smoking.
