Human papillomavirus vaccine knowledge and conspiracy beliefs among secondary school students in Lebanon

Human Papillomavirus (HPV) is widely prevalent across the globe. In Lebanon, the society is transitioning from traditional conservatism to a more open attitude. Although previous studies have examined the knowledge of adults in Lebanon with regard to HPV and its vaccine, there is a lack of research on secondary school students. Moreover, HPV is considered a worldwide public health matter that needs to be addressed. Therefore, the objective of our study is to assess factors associated with knowledge and conspiracy beliefs towards HPV vaccine among a sample of Lebanese adolescents.

Between December 2022 and February 2023, we conducted a cross-sectional study on Lebanese adolescents aged 15 to 18 years old. Parental approval was needed in order to participate. We used a questionnaire to collect data, which included the HPV-knowledge questionnaire (HPV-KQ) and the Vaccine Conspiracy Belief Scale (VCBS).

Of the 406 participants who filled the survey, 64.8% were female, with a mean age of 16.62 ± 1.01. Results showed that 31.0% of students had high knowledge about HPV, while 27.6% had high conspiracy beliefs, and 48% of participants relied on the internet to access information on HPV. Students who had previously heard of HPV, received sexual education at school or outside, and had received at least one dose of the HPV vaccine demonstrated significantly higher knowledge of HPV. Additionally, students with high knowledge had a lower mean House Crowding Index, and those whose fathers had a university education had lower conspiracy beliefs. Females had a higher vaccination rate than males, while no significant difference was found between those who had engaged in sexual activity and those who had not. The multivariate analysis indicated that previous awareness of HPV and receiving sexual education outside school were significantly associated with higher knowledge.

Our study brings to light the urgent need for action to increase HPV awareness and vaccination among Lebanese secondary school students. The prevalence of vaccine misconceptions and conspiracy beliefs and the limited knowledge of HPV underscore the importance of more comprehensive sexual education in schools and the dissemination of accurate information about HPV and its vaccine. Furthermore, given the low vaccination rate among males, efforts should be made to promote HPV vaccination among this population. Addressing these issues can improve public health and help prevent the spread of HPV and its related diseases.
