Better knowledge and understanding of students' health attitudes and behaviours are necessary to more effectively plan targeted prevention strategies. A survey conducted among 617 students at the University Institute of Technology in Poitiers showed that although some indicators affirm good health (relationships with friends and family, appropriate contact with care providers in the health system and regular visits to prevention centres, sexual life, and sports and physical fitness), other indicators reveal a certain amount of suffering among the student population. Students reported suicidal thoughts, symptoms of poor well-being (fatigue, sleeping disorders, concentration problems, sadness or depression) and poor eating habits and/or eating disorders. Consumption of both legal and illegal products seems to be a means utilised to facilitate the social integration process for some students. Therefore, this underlines a significant challenge for prevention campaigns to develop an alternative role model, which promotes the image and profile of a healthy student, with a strong sense of self-esteem, who is well-integrated with his peers without having to engage in substance abuse.
