Orthorexia nervosa: relationship with obsessive-compulsive symptoms, disordered eating patterns and body uneasiness among Italian university students

Introduction: The present study aimed to investigate the relationship between ORTO-15 score and obsessive-compulsive symptoms, disordered eating patterns and body uneasiness among female and male university students and to examine the predictive model of ORTO-15 in both groups. Methods: One hundred and twenty students participated in the present study (mean age 22.74 years, SD 7.31). The ORTO-15 test, the Maudsley Obsessive-Compulsive Questionnaire, the Eating Attitudes Test-26 and the Body Uneasiness Test were used for the present study. Results: Our results revealed no gender differences in ORTO-15 score. Our results show, rather unexpectedly, that in female students lower scores, corresponding to greater severity, were related to less pathological body image discomfort and obsessive-compulsive signs, while in male students, lower ORTO-15 scores were related to less pathological eating patterns, as behaviors and symptoms. Conclusion: Further studies regarding the relationship between ON and anorexia nervosa, as well as obsessive-compulsive symptoms, are needed to better understand the causality.
