ABSTRACT Introduction: It is difficult to detect athletes at risk of eating disorders. Objective: The aim of this study was to create a predictive equation for eating disorder risk behaviors (EDRB) in female athletes. Methods: 484 athletes participated in the study. The Eating Attitudes Test (EAT-26) was used to assess EDRB. The Sociocultural Attitudes Towards Appearance Questionnaire-3 was used to analyze the sociocultural influence on body image. The Body Shape Questionnaire and the Body Checking and Avoidance Questionnaire were used to assess body dissatisfaction in relation to thinness, and body checking, respectively. Skinfold thickness, body weight and height were also measured. The demographic data collected were age and weekly training regime. Results: The findings indicate that body mass index (BMI), body fat percentage (BF%), sociocultural influence, body checking and body dissatisfaction in relation to thinness explain 23% of the EDRB variance (p = 0.001). The results showed no difference between the EAT-26 scores and the predictive equation (p = 0.27). Conclusion: It was concluded that the predictive equation is reliable for evaluating EDRB in female athletes. Level of evidence III; study case-control.
