E-Cigarette Use among University Students from One University in Hanoi, Vietnam, and Associated Factors.

ABSTRACT

OBJECTIVE: Describe the use of e-cigarettes and factors associated with e-cigarette use among university students from one university in Vietnam in 2021. METHODS: This cross-sectional study was conducted with a total of 554 full-time undergraduate students recruiting for the study. Data was collected using a structured self-administered questionnaire. A logistic regression analysis was performed to identify factors with significant association with students' use of e-cigarettes. RESULTS: The study revealed that 13.2% of students were current users. Students who had e-cigarette smokers in the family (aOR=6.1, 95% CI 2.5-15.4; p<0.001), used traditional cigarettes (aOR=23.6, 95% CI 10.5-53.4; p<0.001), consumed alcohol (aOR=5, 95%CI 1.6 - 15.9; p<0.01), were exposed to e-cigarette advertising (aOR=2.6; 95%CI 1.1-5.9; p<0.01), and  had inadequate knowledge about e-cigarettes (aOR=2.2; 95%CI 1-4.7; p<0.01) were more likely to use e-cigarettes. CONCLUSION: This study updates the status of e-cigarette use among students in one university in Vietnam, thereby suggesting strategies to reduce the use of e-cigarettes among university students.
