BACKGROUND: The aim of this study was to investigate knowledge, attitudes, and behaviors in high school students analyzing habits and level of knowledge regarding the intake of substances that help enhance sports performance. METHODS: The study was conducted at 27 public secondary schools of Marche. The survey was conducted in the form of a self-administered questionnaire (a modified version of Behavioral Risk Factor Surveillance System Questionnaire). RESULTS: The total sample consisted of 755 high school students with an average age of 17.91±0.04 years, 422 males (55.89%) and 333 females (44.11%). Ninety students (11.92%) indicated use creatine and branched-chain amino acids, with prevalence in male (87.44%). Twenty-four male students (3.18%) out of 755 surveyed adolescents indicated the use of doping substances: 8 (1.06%) anabolic-androgenic steroids (AAS) and 16 (2.12%) stimulants. Among the 755 students surveyed, 662 (87,68%) had poor knowledge about doping. Multivariate model has confirmed the association between poor knowledge about doping and frequency at technical superior school (OR 0.48; 95% CI: 0.28-084; P<0.05) and use of creatine/BCAAs (OR 0.23; 95% CI: 0.07-0.75; P<0.05). CONCLUSIONS: High school students are poorly educated and do not receive enough information by those who have authority to do so as coaches and family doctors. Well-designed educational interventions are necessary.
