Factors Associated with Knowledge and Attitude towards E-Cigarettes among Undergraduate Students in Thailand: A Cross-Sectional Study

Thailand government has enacted a ban on vaping for eight years, but the number of vapers has continued to increase, particularly among teenagers. This study aimed to evaluate undergraduate pharmacy students' knowledge and attitudes toward e-cigarette use in Thailand. This descriptive cross-sectional study was performed between January and March 2022. The participants were selected from 14 universities of Thailand. For data collection, a questionnaire was developed online using Google Form. The participants had to complete the questionnaire within 5 to 10 days the via s. Chi-square and binary logistic analysis were used to assess the association between variables. A total of 507 participants were recruited, The participants' mean age was 20.6 ± 1.9 years. About 98.6% of the participants knew about e-cigarette, and 74.4% had never been taught about e-cigarettes. Moreover, 68.8% of the participants declared that people around them were smokers. Logistic regression analysis indicated that the participants who declared that they were not sure if e-cigarettes contains nicotine or not were 10.5 more likely to consume e-cigarettes (AOR = 10.5; 95 % CI 3.130-35.181; P ˂0.001). Male participants who were at the academic year of three and four were more likely to use e-cigarettes than female students who were at the academic year of five and six (AOR 2.9; 95 % CI 1.599-5.214; P ˂0.001; AOR = 4.5; 95 % CI 1.412-14.571; P ˂0.001; AOR = 3.9; 95 % CI 1.263-12.511; p = 0.018). OOur study findings showed that pharmacy students lacked knowledge about e-cigarettes and misunderstood about e-cigarettes substances. Future research is necessary to develop educational programs for health professionals to be ready to advise patients about e-cigarettes.
