Abstract:
Adherence of adolescents to health practices in the context of sexuality is relevant, not only from the point of view of physical and psychological well-being, but also the model effect of their knowledge of infections transmitted sexually and their behaviours may have on other adolescents and lifestyles adopted. The need thus emerges to work with this target group with issues related with their knowledge of sexually transmitted infections, debating and reflecting on everyday situations of social life in the context of sexuality.
