Supplementary Material for: Enhancing HPV vaccination rates through better knowledge? - Insights from a survey among German medical students

Introduction: Vaccination against human papillomavirus (HPV) significantly reduces the risk for malignant diseases like cervix, anal or penile cancer. However, although vaccination rates are rising, they are still too low mirroring a lack of disease awareness in the community. This study aims to evaluate knowledge about HPV vaccination as well as the vaccination rate among German medical students.
Material & methods: Medical students were surveyed during a German medical students' football tournament. The self-designed survey on HPV vaccination consisted of 24-items. The data collection was anonymous.
Results: Among 974 participating medical students 64.9% (632) were women, 335 (34.4%) were male and 7 (0,7%) were non-binary. Mean age was 23.1 +- 2.7 (+- standard deviation (SD); range 18-35) years. Respondents had studied mean 6.6 +- 3.3 (1-16) semesters and 39.4% (383) had completed medical education in urology. 613 (64%) respondents reported that HPV had been discussed during their studies. 7.6% (74) had never heard of HPV. In a multivariate model female gender, the knowledge about HPV, and having worked on the topic were significantly associated with being HPV-vaccinated. Older students were vaccinated less likely.
Conclusions: Better knowledge and having worked on the topic of HPV were associated with a higher vaccination rate. However, even in this highly selected group the knowledge about HPV vaccination was low. Consequently, more information and awareness campaigns on HPV vaccination are needed in Germany to increase vaccination rates.
