“…Indeed, the suitability of some of the items has been debated by some researchers, for example, Missbach et al [ 13 ] who question whether item 1 regarding calories provides valid information, considering that, generally speaking, a person with orthorexia is considered to worry more about the quality of food as opposed to the quantity of the same. Likewise, the idea that orthorexia may be a subphase within the healing process of other eating disorders such as anorexia, as other research has suggested [ 33 , 34 ], may favor the inclusion of this item. The many divergent study results and clinical opinions about ON suggest that the scientific and medical communities must continue to work together toward a clearer understanding of the disorder and its symptoms, as well as for the development of a more reliable standard screening tool.…”

PurposeThe ORTO-11-ES questionnaire is a tool to assess the pathological obsession displayed by some individuals regarding healthy eating. 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).MethodsThe sample comprised 492 students from the University of Castilla la Mancha, Spain. Of these, 280 were women (56.9%). Participants were surveyed using the ORTO-11-ES questionnaire.ResultsThe 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. The tendency towards orthorexic behavior is more associated with the female gender. The BMI had no influence on the tendency for ON.ConclusionsThis study is the first attempt to confirm the three-factor structure of a Spanish version of the ORTO-15 questionnaire. These findings suggest that the ORTO-11-ES may be a valuable tool for identifying subjects with specific eating behavior patterns. 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.Level of evidenceLevel V, descriptive cross-sectional study.Electronic supplementary materialThe online version of this article (10.1007/s40519-018-0573-3) contains supplementary material, which is available to authorized users.

“…Taking into consideration only the DOS with its proposed cutoff (score ≥ 30) the prevalence of ON in a representative German sample was estimated to be 6.9% [25]. Additional findings have revealed that the prevalence rate of ON among university students was 3.3% in a German sample [26], 7.8% in a Chinese sample [24], 8% in a U.S. sample [22] and 10.5% in a Spanish sample [23].…”

Purpose Although orthorexia nervosa, the fixation on health-conscious eating behaviour, was first described in the 90 s, there is no clear understanding whether existing ON measures are appropriate for its assessment. The objectives of the present study were to: (1) examine the psychometric properties of the Polish version of the DOS (PL-DOS) and to compare the PL-DOS with the English version of the DOS (E-DOS) as well as (2) evaluate the prevalence of ON among Polish university students and compare the prevalence rates of ON among Polish and U.S. students. Methods Four-hundred and twelve students (77.2% female) with a mean age of 24.62 years (SD = 6.86) participated in the present study. All participants completed the Polish version of the Düsseldorf Orthorexia Scale (PL-DOS), the Eating Habits Questionnaire (EHQ) and the Eating Disorder Inventory (EDI). Results Reliability analysis for the PL-DOS showed strong internal consistency with a Cronbach’s alpha coefficient of 0.840 and a coefficient omega of 0.840, 95% CI [0.808, 0.866]. Significant correlation coefficients were found between the PL-DOS and all subscales of the EHQ. Confirmatory factor analysis showed that the one-factor model had poor fit. Polish students had an ON prevalence rate of 6.6%, lower than that of U.S. students (8%). Conclusions Our findings validate the use of the PL-DOS as an appropriate ON measure for a Polish population. Level of evidence Level V, cross-sectional descriptive study.

“…So scheint die ursprüngliche Beobachtung und Annahme, dass ON üblicherweise bei Männern auftritt [12], so nicht mehr haltbar. Wenige Studien zeigen entweder erhöhte Werte bei Männern [2,28,78] oder Frauen [24,29,43,68,73,79], die überwiegende Mehrzahl ( > 20 Studien) deutet jedoch auf ähnliche Fallzahlen bzw. vernachlässigbare Unterschiede, z.…”

Orthorexia nervosa: Verhaltensauffälligkeit oder neue Störungskategorie?

ZusammenfassungZahlreiche epidemiologische Studien zeigen, dass es sich bei Orthorexia nervosa, der zwanghaften Fixierung auf gesundes Essen, um ein bekanntes und verbreitetes Phänomen in verschiedenen Ländern und Kulturen handelt (Prävalenzen zwischen 1 und 7% in der deutschen Allgemeinbevölkerung). Die Diskussion, ob es sich dabei jedoch lediglich um ein gesellschaftliches Phänomen bzw. Verhaltensauffälligkeit handelt, eine (subklinische) Essstörung oder eine Zwangsstörung, oder ob man dieses Verhalten zur Gruppe der Verhaltenssüchte zählen sollte, steht dabei ganz am Anfang. Nur wenige Studien beschäftigen sich mit dieser differenzialdiagnostischen Abgrenzung. Unter Beachtung der Uneinigkeit in Bezug auf die Definition des Phänomens legen aktuelle Studien am ehesten eine Klassifizierung im Rahmen der Essstörungen nahe. Zweifel entstehen v. a. aus dem deutlichen Überlappungsgrad zu anderen Lebensstilmerkmalen. Ähnlich rar sind Studien, die die klinische Relevanz eines orthorektischen Essverhaltens nachzeichnen sowie mögliche Entstehungsmechanismen thematisieren. Alter und Geschlecht spielen nach aktuellen Erkenntnissen eine eher untergeordnete Rolle. Studien zum Einfluss von Bildung und Gewicht deuten auf einen schwachen bis moderaten U-förmigen Zusammenhang mit orthorektischen Verhaltensweisen. Ebenso werden Aspekte wie Schönheitsideal, Perfektionismus sowie Fitness- und Gesundheitsorientierung immer wieder als relevant beschrieben. Studien zu neuropsychologischen und biologischen Korrelaten fehlen fast komplett. Der vorliegende Artikel gibt einen Überblick über den aktuellen Forschungsstand, zeigt verschiedene Erklärungsansätze und reflektiert kritisch über den aktuellen Wissensstand.

Prevalence and predictors of orthorexia nervosa among German students using the 21-item-DOS

Abstract: The prevalence of ON appears to be low in this sample of German university students. Female NS students do not seem to have higher prevalence of ON or risk of developing ON.
