The goals of this study is: a) to evaluate the prevalence of eating disorders in a non-clinic population of students; b) to identify the group at risk in this population. Methodology: In order to accomplish the goals we conducted a non experimental, transversal, correlational quantitative study. The population for this study is composed by 1388 High School and Undergraduate Students from the Central area of Portugal. All students filled in an anonymous questionnaire, consisting of socio-demographic, recent weight history, DSM IV criterion for bulimia and anorexia and EDI 1. Outcome: In accordance with the DSM IV criterion, we found no case of anorexia. In the case of the girls of the first group (14-17 years) we found 3.4% of partial situations of restrictive anorexia probable cases and 6.3% cases of bulimia. In the case of the older girls (18-25 years), we identified 1.4% of partial situations of anorexia and 3.4% of bulimia. In the case of the boys of the first group (14-17 years), we found 1.1% of sub-clinical situations of anorexia and 3.5% of bulimia. With the older boys (18-25 years) the values are slightly lower: we didn’t find any situations of partial anorexia and found only 0.6% behaviours that can be framed as situations of bulimia.
