Evaluation of Polish Adolescents' Knowledge About Human Papillomavirus and Vaccines.

Human papillomavirus (HPV) vaccination can prevent more than 90% of cancers caused by HPV. However, they are still not common in Poland. The aim of the study was to evaluate Polish youths' knowledge of HPV vaccine and sexually transmitted diseases (STD). The cross-sectional study was performed with the use of an anonymous and voluntary survey distributed among 610 graduate high-school students, and 491 (81%) responded. Only 24% were aware of potential oncological risk of HPV infection. Nearly all responders indicated HIV/AIDS as STD, while only 14% indicated HPV as well. In the opinion of 94% participants, vaccines are effective and safe, however, only 8% of girls and 5% of boys claimed that they were vaccinated against HPV. Simultaneously, 43% declared the will to vaccinate their own child in the future. As a barrier in performing HPV vaccinations, participants indicated first of all lack of enough knowledge (64%) and lack of awareness of the need to be vaccinated (51%). The main sources of knowledge about health were internet (93%) and school (67%). Only 10% of the participants had discussed the HPV and vaccine with a doctor. These adolescents had more knowledge about cervical cancer ( = 0.0002) and its relation to HPV infection ( = 0.0001). Polish adolescents present positive attitude toward HPV vaccines but their knowledge is still unsatisfactory. Schools and professional health providers should pay more attention to patient's education as well as developing online campaigns.
