![]() ![]() Alterations in brain chemistry, specifically dopamine and serotonin, may cause feelings of euphoria and/or anxiety. If unable to conform to food rules or dietary ideals, an individual with ON tendencies may develop feelings of self-blame, distorted cognitions, and even psychosis. From a psychological point of view, although empirical long-term studies are lacking, there is anecdotal evidence that this type of dietary extremism is associated with a tendency for affected individuals to seek isolation, limiting social interaction with others. Previously reported physical effects include protein-energy malnutrition, iron-deficiency anemia, vitamin excesses and deficiencies, osteoporosis, cardiovascular abnormalities, hypotension, and trace-element deficiencies. The potential severity of the physical and psychological effects of ON vary considerably, depending on the duration of the behaviors, the specifics of an individual’s eating choices, the level of adherence to food rules, and any underlying or co-occurring conditions. When extreme, ON can lead to physical, psychological, and social impairments, such as malnutrition, isolation, and decreased quality of life. Orthorexia nervosa (ON) is the term given to a constellation of pathological attitudes and behaviors related to attempts to eat only “healthy” or “pure” food. Level V, descriptive cross-sectional study. ![]() ![]() This information may be useful for health professionals involved in the research, development and implementation of interventions catered to individuals suffering from this eating disorder. These findings suggest that the ORTO-11-ES may be a valuable tool for identifying subjects with specific eating behavior patterns. This study is the first attempt to confirm the three-factor structure of a Spanish version of the ORTO-15 questionnaire. The BMI had no influence on the tendency for ON. The tendency towards orthorexic behavior is more associated with the female gender. The confirmatory factor analysis (CFA) supported the 11 elements and 3 domains of this tool as the better fitting model for the Comparative Fit Index (CFI) and the Tucker–Lewis Index (TLI), the values were 0.94 and 0.91, respectively, and the Root Mean-Square Error of Approximation (RMSEA) was 0.058. Participants were surveyed using the ORTO-11-ES questionnaire. The sample comprised 492 students from the University of Castilla la Mancha, Spain. The aims of this study were (1) to confirm the factor structure of the Spanish version of ORTO-11-ES using confirmatory factor analysis (CFA) and (2) to examine the possible association between the ORTO-11-ES score, gender and body mass index (BMI). The ORTO-11-ES questionnaire is a tool to assess the pathological obsession displayed by some individuals regarding healthy eating. ![]()
