Background: Electronic cigarettes (e-cigarettes) have been increasing in popularity among young adults due to the misconception about the safety of e-cigarettes. Our study aims to identify the prevalence rate of e-cigarette use among college students, the reason behind their use, and the relationship between the use of electronic cigarettes and cardiovascular symptoms among college students.
Methods: An online questionnaire was sent to students of Taibah University between 2021 and 2022. Data from this survey were analyzed to obtain the prevalence of e-cigarette use among Taibah University students and to compare the demographic and health characteristics differences between e-cigarette users and non-users. The prevalence of cardiovascular symptoms was also compared between the two groups.
Results: A total of 519 students participated in this study. The prevalence rate of e-cigarette use was 24%. Compared to non-users, e-cigarette users were more likely to be male (71% vs. 40%, p < 0.01), overweight (44% vs. 32%, p = 0.01), and drug users (4% vs. 1%, p = 0.01). E-cigarette users were likelier to complain of cardiovascular symptoms, including chest pain (19% vs. 10%, p = 0.01), shortness of breath (14% vs. 7%, p = 0.02), and palpitation (12% vs. 6%, p = 0.03). The association between e-cigarette use and cardiovascular symptoms was significant even after adjusting for students' characteristics. Students' main reasons for e-cigarette use were to enjoy the flavors of e-cigarettes, quit tobacco smoking, and improve depression.
Conclusion: The prevalence rate of e-cigarette use among college students was 24%. The self-reported cardiovascular disease symptoms rate was doubled among e-cigarette users compared to non-users.
