[SUS users' knowledge of and attitude to HPV virus and vaccines available in Brazil].

Objective: To investigate knowledge of HPV and HPV vaccines in men and women, users of the Brazilian Unified Health System, and the intention to get themselves and their teenage children vaccinated.

Methods: A descriptive, cross-sectional study with 286 women (18-49 years old) and 252 men (18-60 years old), users of five primary health units and two polyclinics in Campinas, SP, Southeastern Brazil, was carried out. Participants were interviewed in 2011 using a structured questionnaire. Bivariate and Poisson regression analysis were performed to identify variables associated with knowledge of HPV and HPV vaccines, and participants vaccination intentions.

Results: Almost 40.0% of the participants reported having heard of HPV and 28.9% mentioned adequate information. The main information source was the media (41.7%). Only 8.6% of the participants had heard of the HPV vaccines. Once the participants were informed of the existence of HPV vaccines about 94% of them said they would get vaccinated and/or vaccinate their teenage children, if the vaccines were available in the public health system. Schooling of over 8 years and being female were the variables independently associated with having heard of HPV, the vaccines and having adequate knowledge of the virus. Advanced age was associated with having heard of HPV vaccines. There were no variables associated with the vaccination intentions.

Conclusions: These results reinforce the need for educational activities that provide the population with adequate information on HPV and preventive measures.
