| Abstract: | OBJECTIVES: Certain practices with a potential risk of hepatitis C virus (HCV) transmission begin early, during adolescence. In 2004, primary prevention interventions targeting adolescents aged 13-17 years attending school in the Alpes-Maritimes region of France were conducted by the "Réseau Hépatite C Ville H?pital C?te d'Azur". The aim of this study was to assess the adolescents' knowledge about HCV and to evaluate the impact of such interventions.METHODS: A random sample of secondary state schools in the Alpes-Maritimes was invited to participate in the study. Before and after presenting a slide show about HCV in the selected classrooms, the investigators asked the students to complete an anonymous self-administered questionnaire designed to assess their knowledge about HCV infection.RESULTS: The intervention concerned a study population of 2,946 students, mean age 14.4 +/- 2.5 years. Before the interventions, 21% had good knowledge of HCV infection and 24% had good know-ledge of disease contagion. These percentages increased significantly after the interventions to 95% and 84% respectively. Knowledge improvement was more significant among high school students and among students whose parents had an employment.CONCLUSIONS: Adolescents are poorly informed about HCV infection. The present intervention enabled significant improvement in their knowledge about the infection and disease contagion, independently of gender, age and geographical area. |
