Purpose To examine the effect of a 1-yr school-based intervention program to prevent the development of new cases of eating disorders (ED) and symptoms associated with ED among adolescent female and male elite athletes. Methods All 16 Norwegian Elite Sport High Schools were included (intervention group [n = 9] and control group [n = 7]). In total, 465 (93.8%) first-year student athletes were followed during high school (2008-2011, three school years). The athletes completed the Eating Disorder Inventory 2 and questions related to ED before (pretest), immediately after (posttest 1), and 9 months after the intervention (posttest 2). Clinical interviews (Eating Disorder Examination) were conducted after the pretest (all with symptoms [n = 115, 97%] and a random sample without symptoms [n = 116, 97%]), and at posttest 2, all athletes were interviewed (n = 463, 99.6%). Results Among females, there were no new cases of ED in the intervention schools, while 13% at the control schools had developed and fulfilled the DSM-IV criteria for ED not otherwise specified (n = 7) or bulimia nervosa (n = 1), P = 0.001. The risk of reporting symptoms was lower in the intervention than in the control schools at posttest 1 (odds ratio [OR] = 0.45, 95% confidence interval [CI] = 0.23-0.89). This effect was attenuated by posttest 2 (OR = 0.57, 95% CI = 0.29-1.09). The intervention showed a relative risk reduction for current dieting (OR = 0.10, 95% CI = 0.02-0.54) and three or more weight loss attempts (OR = 0.47, 95% CI = 0.25-0.90). Among males, there was one new case of ED at posttest 2 (control school) and no difference in the risk of reporting symptoms between groups at posttest 1 or 2. Conclusion A 1-yr intervention program can prevent new cases of ED and symptoms associated with ED in adolescent female elite athletes.
