ABSTRACT OBJECTIVE To analyze knowledge, attitudes, and practices of adolescent students from public schools in the municipality of Teresina, state of Piauí, regarding human papillomavirus (HPV). METHODS Cross-sectional, analytical study carried out in 12 public schools in the municipality of Teresina, with a random sample of 472 15-year-old adolescents. All participants answered a validated questionnaire, which evaluated sociodemographic characteristics, level of knowledge about HPV, attitudes regarding vaccination and vaccination status. The levels of knowledge and attitude were classified by standardized scores and practice by the vaccination situation. The analyses were carried out using the SPSS software. In the bivariate analysis, simple logistic regression was used generating odds ratios to identify the associations of sociodemographic characteristics, knowledge, and attitude with HPV prevention practice. Variables that presented p-value ≤ 0.20 in the bivariate analysis were inserted in a multivariate logistic regression model. Statistical significance was set at p < 0.05. RESULTS Among the participants, 27.3% had sufficient knowledge, 34.1% had positive attitudes, and 74.6% had adequate practice. In the multivariate analysis, we observed a statistically significant association among females (ORa = 15.62; 95%CI: 9.08–26.9), satisfactory knowledge (ORa = 2.09; 95%CI: 1.15–3.81), and positive attitudes (ORa = 1.89; 95%CI: 1.10–3.23) with proper practice. CONCLUSIONS Being female, having a satisfactory level of knowledge about HPV and the vaccine, and having positive attitudes towards HPV vaccination reinforce the appropriate practice of vaccination. These findings demonstrate the need to expand the knowledge of adolescents, generating positive attitudes towards vaccination within an appropriate perspective.
