RT Journal Article T1 Pathological Preoccupation with Healthy Eating (Orthorexia Nervosa) in a Spanish Sample with Vegetarian, Vegan, and Non-Vegetarian Dietary Patterns A1 Parra Fernández, María Laura A1 Manzaneque Cañadillas, María A1 Onieva Zafra, María Dolores A1 Fernández Martínez, Elia AB Orthorexia nervosa (ON) has been defined as an obsessive and pathological attitudetowards healthy nutrition. The aim of this study was to compare individuals who followed a vegan,vegetarian, and omnivore diet in terms of ON behaviors and to examine their prime motivations,attitudes, and behaviors towards food. The Spanish version of the ORTO-15 test—ORTO-11-ES—and the Food Choice Questionnaire (FCQ-SP) were used with a demographic questionnaire in anonline survey disseminated among the social networks of different vegetarian associations and thegeneral population. Of 466 individuals, 55% followed an omnivore diet, 23.5% were vegetarian and21.7% were vegan. Results revealed relationships between type of diet and FCQ-SP dimensions for:health and natural content (H = 8.7, p < 0.05), sensory appeal (H = 11.4, p < 0.01), weight control(H = 40.4, p < 0.01), and familiarity (H = 37.3, p < 0.01). Our results confirm the findings of recentstudies showing that individuals who follow a vegan or vegetarian diet are more likely to develop apathological preoccupation with healthy eating versus omnivores. Further studies are required todetermine the potential lines of action for the prevention of ON.
