    BACKGROUND: Orthorexia nervosa (ON) is described as an obsessive pathological behavior characterized by a strong preoccupation with healthy eating and the avoidance of foods or ingredients considered unhealthy by the subject. Although it is still not officially recognized as an eating disorder, previous studies have discussed its frequency in some groups and a fifteen-question test (ORTO-15) was developed elsewhere to assess ON behavior. OBJECTIVE: The present study aimed to evaluate ON behavior in a sample of Brazilian dietitians after testing the psychometric properties of the Portuguese version of ORTO-15. METHODS: A total of 392 dietitians answered an online version of the test. The answers were analyzed regarding ON tendency, according with the scoring grid proposed by its authors. Exploratory factor analysis was performed and internal consistency was assessed. RESULTS: It was found that three questions of the test presented loadings lower than 0.5. The 12 remaining question formed 3 factors with internal consistency of -0.51, 0.63 and 0.47. The answers of the participants to these questions revealed a tendency to orthorexic behavior, mainly regarding aspects such as: making food choices conditioned by worry about health status, evaluating food rather from nutritional quality than from its taste, believing that consuming healthy food may improve appearance, discrediting the influence of mood on eating behavior and banning food choices considered by them as eating transgressions. CONCLUSION: There is no evidence of the validity and reliability of the ORTO-15 with the initial psychometric evaluation performed. Further analyses are needed. Nevertheless, it was possible to observe a high frequency of orthorexic behavior among the studied Brazilian dietitians. However, additional studies are needed to completely understand dietitians behavior toward ON. (Eat. Weight Disord. 17: e29-c35, 2012). (C) 2012, Editrice Kurtis

    Ortorexia nervosa: reflexões sobre um novo conceito
    (Pontifícia Universidade Católica de Campinas, 2011-04-01) Martins, Márcia Cristina Teixeira; Alvarenga, Marle Dos Santos; Vargas, Sílvia Viviane Alves; Sato, Karen Sayuri Cabral De Jesus; Scagliusi, Fernanda Baeza [UNIFESP]; Centro Universitário Adventista de São Paulo Faculdade de Nutrição; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)
    Orthorexia nervosa is a new term described as an obsessive pathological behavior characterized by fixation on healthy eating. It has not yet been officially recognized as an eating disorder, but its concept, characteristics, interactions and symptoms have been discussed. This work presents a review of the articles published on the theme since 1997, when orthorexic behavior was first described. Similarities and differences between orthorexic behavior and the more common eating disorders, such as anorexia nervosa and bulimia nervosa, are discussed. To date, one instrument was developed and validated to detect orthorexic behavior. Studies indicate that some groups are more vulnerable to orthorexia nervosa: medical students, physicians, dietitians, individuals with anxiety symptoms, obsessive-compulsive individuals and those who overvalue a perfect body. The discussion on orthorexia nervosa is based on analyzing the concepts of eating attitude and healthy eating, and seeks a biopsychosocial focus for proper eating in addition to a physiological focus. To date, there are no studies about orthorexia nervosa in Brazil. Nevertheless, this subject is worthy of discussion since health professionals should be made aware of the existence of this deviant behavior and its possible consequences, not only for someone's physical and emotional health, but also for the understanding of healthy eating.
