Prevalence of eating disorders and the predictive power of risk models in female elite athletes: a controlled study.
The purpose s of this study were to examine the percentage of female elite athletes and controls with disordered eating ( DE ) behavior and clinical eating disorders ( EDs )  , to investigate what characterize the athletes with EDs , and to evaluate whether a proposed method of screening for EDs in elite athletes does not falsely classify sport-specific behaviors as indicators of EDs . All athletes representing the national teams at the junior or senior level , aged 13 - 39 years ( n=938 ) , and age-group matched , r and omly selected population -based controls ( n=900 ) were invited to participate . From the screening data , a r and om sample of athletes ( n=186 ) and controls ( n=145 ) were subjects for a clinical interview . More athletes in leanness sports ( 46.7 % ) had clinical EDs than athletes in non-leanness sports ( 19.8 % ) and controls ( 21.4 % ) ( P<0.001 ) . Variables predicting clinical EDs , and thus c and i date s for valid screening procedures , were menstrual dysfunction in leanness athletes , self-reported EDs in non-leanness athletes , and self-reported use of pathogenic weight control methods in controls . Hence , statistically based risk factors are not universally valid , but specifically related to athletes and non-athletes , respectively
