Knowledge, beliefs, attitude, and practices of E- cigarette use among dental students: A multinational survey

Background E-cigarette use is a trend worldwide nowadays with mounting evidence on associated mor- bidities and mortality. Dentists can modify the smoking behaviors of their patients. This study aimed to explore the knowledge, beliefs, attitude, and practice of E-cigarette use among dental students. Materials and methods This multinational, cross-sectional, questionnaire- based study recruited undergraduate dental students from 20 dental schools in 11 countries. The outcome variable was current smoking status (non-smoker, E-cigarette user only, tobacco cigarette smoker only, dual user). The explanatory variables were country of residence, sex, age, marital status, and educational level. Multiple linear regression analysis was performed to explore the explana- tory variables associated with E-cigarette smoking. Results Of the 5697 study participants, 5156 (90.8%) had heard about E-cigarette, and social media was the most reported source of information for 33.2% of the participants. For the 5676 cur- rent users of E- cigarette and/or tobacco smoking, 4.5% use E- cigarette, and 4.6% were dual users. There were significant associations between knowledge and country (P< 0.05), educational level (B = 0.12 ; 95% CI: 0.02, 0.21 ; P = 0.016) and smoking status (P< 0.05). The country of residence (P< 0.05) and smoking status (P< 0.05) were the only statistically significant factors associated with current smoking status. Similarly, there were statistically significant associations between attitude and country (P< 0.05 for one country only com- pared to the reference) and history of previous E-cigarette exposure (B = -0.52 ; 95% CI: -0.91, -0.13 ; P = 0.009). Also, the practice of E-cigarettes was significantly associated with country (P< 0.05 for two countries only compared to the reference) and gender (B = -0.33 ; 95% CI: -0.52, -0.13 ; P = 0.001). Conclusion The knowledge of dental students about E-cigarette was unsatisfactory, yet their beliefs and attitudes were acceptable. Topics about E-cigarette should be implemented in the dental curriculum.
