Fatores ambientais associados à cobertura da vacina contra o papilomavírus humano em adolescentes: análise de 2016 a 2020

Abstract

Objective: to analyze the association between the factors of the social environment and the coverage rates of the human papillomavirus (HPV) vaccine in adolescents, in the State of Minas Gerais, Brazil. Method: this is an epidemiological, ecological study, with panel and trend analysis from 2016 to 2020. The population consisted of adolescents aged 9 to 13 years. The environmental variables were coverage rates, the municipal index of human development, income, education, and longevity; and the rate of violence. The Prais-Winsten autoregression and the panel regression model were used, in addition to the estimate of the mean annual percentage variation. Results: the vaccination coverage rates are below the goals recommended by the Ministry of Health for all regions analyzed. Moreover, these rates are associated with factors related to the application of the first dose and to aspects inherent to the social environment, such as the rate of violence. Conclusion: our findings showed that, although tenuous, aspects of the environment, in addition to individual characteristics, provide relevant information to understand the occurrence of health outcomes, since this vaccination campaign presents a strong influence of the environment and age as factors associated with the low rates.
