Résumé Introduction L’industrie pornographique est omniprésente chez les adolescents qui sont pratiquement tous exposés via Internet, volontairement ou non, et à un âge plus ou moins précoce. Existe-t-il un lien entre l’exposition à la pornographie et certaines conduites à risque ? Méthode Huit cent douze étudiants lillois ont répondu anonymement à un questionnaire proposé à l’occasion d’une consultation en centre de santé. L’analyse statistique a été menée à l’aide de régressions logistiques et linéaires. Résultats L’exposition à la pornographie concerne pratiquement tous les hommes et 80 % des femmes. L’âge moyen de la première exposition est de 15,2 ans. La précocité d’exposition est liée à une activité sexuelle plus précoce, à une recherche de partenaires occasionnel(le)s plus fréquente et à une consommation de cannabis plus fréquente. L’âge d’exposition ne semble pas en revanche influencer le nombre de partenaires sexuel(le)s, le fait de pratiquer la pénétration anale, la consommation d’alcool ou de tabac, l’utilisation de contraceptifs et la prise de risque vis-à-vis des infections sexuellement transmissibles. Le fait de regarder fréquemment des images pornographiques est lié à une activité sexuelle plus précoce, à un plus grand nombre de partenaires sexuel(le)s, au fait de rechercher des partenaires occasionnel(le)s, à une pratique de la pénétration anale, à une moindre prévention des infections sexuellement transmissibles et des grossesses non désirées et enfin à une augmentation des consommations d’alcool et de cannabis. En conclusion, ces résultats doivent interpeller et amener tous les acteurs de santé sexuelle et d’éducation à la sexualité à renforcer l’information donnée aux adolescents. Summary Introduction The pornography industry is a pervasive influence on adolescents, nearly all of whom are exposed to it via the internet, either willingly or unwillingly and at a more or less premature age. Is there an association between exposure to pornography and some forms of risk behaviour? Method Eight hundred and twelve Lille students responded anonymously to a questionnaire given to them on the occasion of a consultation at a health centre. Logistic and linear regressions were used for statistical analysis. Findings Nearly all men and 80% of women had been exposed to pornography. The average age of initial exposure was 15.2 years. Exposure at a premature age is associated with sexual activity at a younger age and with a greater inclination to seek out casual partners and use cannabis more frequently. The age of exposure does not on the other hand appear to have any influence on the number of sexual partners, the practice of anal penetration, alcohol or tobacco consumption, contraceptive use and taking risks in terms of sexually transmitted infections. Frequent viewing of pornographic images is associated with sexual activity at a younger age, a larger number of sexual partners, an inclination to seek out casual partners, the practice of anal penetration, a lower level of prevention of sexually transmitted infections and unwanted pregnancies and finally, a higher consumption of alcohol and cannabis. In conclusion, these findings should be taken into account, and should lead those involved in sexual health and sex education to increase the amount of information they provide to adolescents.
