Introduction: Electronic cigarettes are increasingly popular worldwide, especially among youth. There is growing evidence of the negative health consequences of vaping. Our objective was to assess university students' knowledge and attitudes regarding electronic cigarettes (e-cigarettes), their use, as well as the associated influencing factors for their use.
Methods: The study involved an online cross-sectional survey conducted between November 2019 and March 2020 in a university in Hangzhou, China. A total of 563 students completed the questionnaire. Descriptive statistics were used to assess characteristics, knowledge, and attitudes; t-tests, χ2-tests and logistic regression models were used to identify factors associated with ever e-cigarette use.
Results: In all, 59.9% of respondents were female and the average age was 20.38 years (SD=1.32). Only 42.6% of the respondents thought that e-cigarettes contain nicotine, 31.1% thought e-cigarettes are tobacco products, and 8.2% of the students reported being ever e-cigarettes users. In regard to attitude, the average score of the students in the Safety dimension was 3.34 (SD=0.64), followed by the Restriction dimension (Mean=2.66, SD=0.83). Correlates of ever use included regions, friends' and roommates' ever e-cigarette use, and higher attitude score in the Supervision dimension.
Conclusions: The university students' level of knowledge regarding e-cigarettes was not high, and their attitudes regarding e-cigarettes were not that supportive. Students' ever use of e-cigarettes at a university in Hangzhou was higher than for university students in other cities in China, but lower than for those in foreign countries.
