Objective: to investigate the knowledge and attitude of school adolescents regarding sexual violence. Method: a qualitative study with data gathering, based on Maurice Merleau-Ponty’s Phenomenology of Perception, conducted in April 2018 with 12 adolescents from a state school in Recife, using the focus group technique. For data systematization, thematic content analysis was used in the following steps: pre-analysis, material exploration, treatment of results and interpretation. Results: three thematic categories were established: adolescents’ perceptions of sexual violence; reflective construction of adolescents on the factors of exposure to sexual violence; and facilitating aspects for the prevention of adolescent sexual violence. Conclusion: the perception of adolescents regarding sexual violence is influenced by cultural, structural, social, economic, psychological and biological aspects, which should be considered in the planning of actions aimed at preventing sexual violence for this public.

Objetivo: analisar as evidências científicas sobre os fatores de risco associados à exposição de adolescentes à violência sexual.Síntese de conteúdo: revisão integrativa da literatura, realizada em quatro bases de dados e duas bibliotecas virtuais, sem limites do ano de publicação, utilizando-seos descritores: “delitos sexuais”, “adolescentes” e “fatores de risco”. Utilizou-se, também, a palavra-chave “violência sexual” e equivalentes, no idioma inglês. Na análise dos 22 artigos incluídos, os fatores associados à exposição dos adolescentes à violência sexual foram classificados em “abuso sexual” e “exploração sexual”. O consumo de álcool e/ou drogas foi o fator mais evidente, seguido do sexo casual, dabaixa escolaridade, da baixa renda, da violência familiar, dos relacionamentos em ambientes virtuais, da estigmatização do trabalho sexual e falta de moradia.Conclusão: os fatores apresentados devem ser considerados pela enfermagem para o reconhecimento de adolescentes vítimas de violência sexual, além de contribuir na prevenção de novos casos e na minimização dos efeitos que tal ato pode causar na vida desse público.

Objectives: to demonstrate the effectiveness of educational interventions in knowledge, attitude and practice for preventing respiratory infections in adults and older adults. Methods: this is a systematic review carried out in 11 databases. Primary studies, without language and time restrictions, of the randomized, non-randomized and before-and-after clinical trial type, were selected. The risk of bias was assessed by two independent researchers, and the methodological quality was generated by the Grading of Recommendations, Assessment, Development and Evaluation. Results: the intervention effectiveness was evidenced in seven studies. The results of the random effects meta-analysis show that there is a statistically significant difference between knowledge about preventing respiratory diseases, with an OR of 2.82 (95%CI 1.70 to 4.69) for the occurrence of events represented by improved knowledge. Conclusions: most studies show the effectiveness of educational interventions, which was determined through the Knowledge, Attitude and Practice survey.
