Abstract
Background: Electronic cigarette (e-cigarette) is becoming increasingly popular worldwide, and commercially a commonplace in the media. Health concerns and the avoidance of smoking are the most frequently reported factors for conventional smokers to turn to e-cigarettes. However, there is insufficient information about the use of e-cigarettes in Makkah city; therefore, this study aims to determine the prevalence of electronic cigarette uses among medical students at Umm al-Qura University (UQU). Methods: A cross-sectional study was conducted in February 2020 among medical students at UQU, Makkah, Saudi Arabia. Data were collected using a prevalidated printed version of a self-questionnaire to determine the prevalence and the main factors that influence medical students to smoke e-cigarettes and to evaluate their awareness, knowledge, and attitude. Results: Out of 1249medical students, 910 participated in the survey, about 31.8 % of them confirmed using e-cigarette regularly. 14.7% think e-cigarettes are medically approved method for smoking cessation, while 59.5% believe it can cause addiction similar to tobacco cigarettes. Among the regular users, 24.3% used it to quit tobacco smoking, 18.9% think it is less harmful, 20.3 % use it because it is less costly, and 18.9% because of stress. Also, 28.4% found it tasty. 30.8% believed that it is less harmful, about 74% stated that they received information about e-cigarettes and only 16% of them received it from medical school. Conclusion: The prevalence of e-cigarette uses among medical student in UQU found to be relatively high, and their overall knowledge is insufficient, which conflict our hypothesis.
