“…Using the ORTO-15 test, ON prevalence rates range from 6% to nearly 90% [30]. While using the DOS, ON incidence ranges from 1% to 8% [31]. Such diversity of ON prevalence could result from the difference in the psychometric quality of the questionnaires [32,33] and lack of an optimal cut-off value (e.g., a cutoff score of 35 based on the ORTO-15 [27]; a cutoff score of 30 or higher based on the DOS [29]; a cuttoff score of 72 based on the ONI [31]).…”

Although the ORTO-15 has good predictive validity [27], the lack of basic psychometric properties and the internal consistency has been criticized [32].…”

Although the amount of research about orthorexia nervosa (ON) has grown in the last two decades, to date, research on ON remains inconsistent. More is known about some behavioral characteristics of ON and its prevalence but nothing is known about the profile analysis behind this pathological eating behavior maintenance. Therefore, the objective of the present study was to determine the profiles of the participants in terms of eating behaviors, eating disorder psychopathology, obsessive-compulsive disorder symptoms and physical activity as well as check their association with ON. The sample was composed of 229 Polish female and male adults. Our findings showed three clusters and four-related factors (obsessive-compulsive disorder features; inappropriate eating and body-related behaviors; psychological and affective traits of eating disorders; perfectionism and behaviors associated with weight maintenance or weight loss). In our sample, a higher percentage of adults belonging to cluster 1 had no ON, whereas a higher percentage of adults belonging to cluster 3 had ON. Our results emphasize the possibility to target pathological eating behaviors and obsessive-compulsive disorder (OCD) symptoms in ON in psychological intervention.

“…6 Although there are several better measures than ORTO-11 to assess orthorexic tendencies like the Eating Habits Questionnaire, the Orthorexia Nervosa Inventory, and the Düsseldorf Orthorexia Scale, we could not use them since they have not yet been validated in Turkish. [45][46][47] We did not question whether the participants in our sample did intense exercises or why they did exercise. To generalize this study's results, longitudinal studies involving participants from different cultures, investigating obsessive-compulsive personality traits, and examining personality traits' effects on orthorexic behaviors would be useful.…”

Purpose The term orthorexia nervosa is used to describe the pathological fixation associated with consuming healthy food. It is assumed that orthorexia nervosa shares some phenomenological features with anorexia nervosa, obsessive-compulsive disorder (OCD), and other mental disorders. Individuals with orthorexic tendencies may have high physical activity as well as a healthy diet. This study aimed to investigate the relationship of orthorexia nervosa with obsessive-compulsive symptoms, eating attitudes, and several sociodemographic features. Patients and Methods We included 63 patients diagnosed with OCD, 63 healthy volunteers who perform physical exercises at least three days a week, at least 30 minutes a day, and 63 healthy volunteers who do not perform physical exercises regularly. Sociodemographic data form, Yale-Brown Obsessive Compulsive Scale, ORTO-11 Scale, Eating Attitude Test, Hamilton Anxiety Scale, and Structured Clinical Interview for DSM-5 Disorders (SCID-5 CV) were administered to all participants. OCD data form was also applied to patients with OCD diagnosis. Results We found a statistically significant relationship between current order-symmetry obsessions and orthorexic tendencies in patients with OCD (p<0.05). There was no relationship between the severity of the disorder and orthorexia nervosa in patients with OCD (p>0.05). Orthorexic tendencies were found to increase as impaired eating attitudes increased in participants who regularly performed physical exercises and patients with OCD (p<0.05). The orthorexic tendencies of participants who regularly performed physical exercises were higher than those diagnosed with OCD and healthy individuals who did not perform physical exercises. Conclusion The absence of a significant relationship between disorder severity and orthorexia nervosa in patients diagnosed with OCD and the increase in orthorexic tendencies as the deterioration in eating attitudes increases in both patients with OCD and the participants who regularly perform physical exercises suggest that orthorexia nervosa may be closer to the eating disorders group than obsessive-compulsive spectrum. Studies with large samples and different diagnoses are needed to determine the place of orthorexia nervosa in diagnosis and classification systems.

“…The prevalence of ON symptoms is less than 1% in the US sample [7], 4.5% in university students [8], 21.4% of pregnant women [9], and 35-57.8% in high-risk groups (for example, artists, athletes, healthcare professionals, and performance artists) [10]. Women are signi cantly more concerned with having a slim body image and dieting than men, and as a result, are more prone to an eating disorder risk.…”

Purpose This study aims to test the effect of the components of the Information-Motivation-Behavioral Skills Model on Orthorexia Nervosa (ON) behavior of pregnant women and health outcomes using a hypothetical model. Methods The study is cross-sectional research and was carried out with 350 pregnant women who had the Non-Stress Test in the obstetrics outpatient clinic of a university hospital. The participants were selected using the convenience sampling method. The data were collected with a questionnaire. Data were analyzed using the structural equation model.Results It was found that 26.6% of pregnant women had an ON tendency. Higher levels of information on healthy eating cause more ON behaviors (β=-0.25, p<.001). The higher motivation for healthy eating (β=0.71, p<.001) and a higher tendency to ON behaviors (β=-0.18, p=.001) are associated with better health outcomes.Conclusion Our findings show that high levels of information and motivation about healthy eating affect ON tendency and health outcomes. The findings are significant in that they lead and guide the interventions for the detection, prevention, and treatment of ON during pregnancy.Level of Evidence: Level V, cross-sectional study
