Abstract
This study aimed to determine the prevalence of chlamydial infection in adolescents entering public juvenile facilities in the province of Quebec and the frequency of their risk behaviours for STDs and HIV infection. Adolescents were asked to complete an anonymous self-administered questionnaire and to be screened for Chlamydia trachomatis. Of 731 sexually active adolescents, 62% agreed to be tested. The overall prevalence rate was 7.7% (95% confidence interval: 5.1% -10.3%). The prevalence was significantly higher in female than in male teenagers: 12% vs 3% (p < 0.001, Fisher’s exact test). These results suggest that screening for chlamydial infection should be offered to all sexually active female teenagers admitted into juvenile facilities. For males, selective screening taking into account sexual history would be a more realistic approach. The frequency of high risk activities for STDs and HIV infection points to the importance of specific prevention programs for this population.
Abrégé
Cette étude visait à déterminer la prévalence de l’infection à chlamydia chez les jeunes admis dans les centres de réadaptation pour adolescents de la province de Québec et d’évaluer la fréquence des comportements à risque de MTS et d’infection au VIH. Les jeunes ont été invités à répondre à un questionnaire anonyme auto-administré et à être dépistés pour Chlamydia trachomatis. Des 731 jeunes actifs sexuellement, 62 % ont accepté d’être testés. La prévalence de l’infection était de 7,7 % (intervalle de confiance à 95 %: 5,1 % à 10,3 %). Elle était significa-tivement plus élevée chez les adolescentes que chez les adolescents: 12 % vs 3 %, (test exact de Fisher, p < 0,001). Ces résultats suggèrent qu’un dépistage de C. trachomatis devrait être offert à toutes les adolescentes sexuellement actives admises en centre de réadaptation. Pour les adolescents, un dépistage ciblé qui tienne compte des comportements à risque serait une approche plus réaliste. La fréquence élevée des comportements à risque justifie le besoin de programmes de prévention spécifiques pour cette population.
