Prevalence of electronic cigarette usage among medical students in Saudi Arabia - A systematic review

The systematic review aimed to report the prevalence of electronic cigarette (e-cigarette) usage among medical students in Saudi Arabia. Electronic databases were searched for scientific research articles published from January 2010 until December 2020. The data search was performed in electronic search engines such as PubMed, Google Scholar, Scopus, Web of Science, Medline, Embase, Cochrane, and Saudi Digital Library. A total of five research articles that qualified the eligibility criteria were analyzed for qualitative data. The sample size in the included studies ranged from 229 to 1007 participants. The prevalence of e-cigarette usage ranged from 10.6% to 27.7% among medical students in Saudi Arabia. Studies have also reported that the prevalence of e-cigarette usage is higher among the male population in comparison with the female population. The prevalence of e-cigarette usage among medical students in Saudi Arabia is high. Similar to tobacco smoking, e-cigarette usage is a major public health issue and concern among the younger population because they have potential benefits in some and are harmful to some and also it is still unclear whether they are effective for quitting smoking. Regulatory bodies must focus and initiate strict laws and policies to minimize the sales of these products to the younger population. Health promotion strategies need to be developed to reduce the usage of e-cigarettes.
