“…It can be assumed that due to the contrasting eating habits of people showing only ON tendency ("ON and without ED") and only ED symptoms ("ED and without ON"), no differences were found in the eating habits of people within the group "ON and ED." In addition, these people were characterized by less frequent consumption of sugar-rich and refined products, which was confirmed by the results of the previous studies on ON [10,26,27] and both AN subtypes-restrictive and binge eating or purging [58,59]. At the same time, people who showed both ON tendency and ED symptoms ("ON and AN") often consumed meat and meat products (upper tertile of DP).…”

“…The researchers first assessed ON tendency in groups following special diets, especially a vegetarian or vegan diet [22][23][24][25], and evaluated the frequency of food intake [26]. To date, other eating habits or dietary patterns (DPs) of people showing ON tendency have only been rarely studied [10,27]. Moreover, knowledge about the differences in the eating behaviors of people with ON and ED is insufficient to confirm both the similarities and differences between these two conditions.…”

Orthorexia nervosa (ON) may precede, ensue, or coexist with eating disorders (ED) and also affect eating behaviors. The aim of this study was to explore the dietary patterns (DPs) and other eating habits of people showing ON tendency, ED symptoms, and both ON tendency and ED symptoms, as well as those not showing either. The data for the study were collected from a sample of 1120 Polish college students through a cross-sectional survey in 2017. The questionnaire used in the survey included the ORTO-15, the Eating Disorder Screen for Primary Care (ESP), and the Food Frequency Questionnaire (FFQ-6), and the students were also asked questions about their eating habits and special diets. A factor analysis was conducted to identify the following five DPs: “high-sugar products and refined products,” “meat and meat products,” “alcohol,” “high-fiber products and nuts,” and “dairy products and whole-meal bread.” Univariate logistic regression analyses were carried out to verify the associations between the variables. Students in the “ON and without ED” group were found to exhibit more healthy eating habits than the students in the “ED and without ON” group. The use of a special diet in the past and currently increased the risk of displaying ON tendency and ED symptoms. Students in the “ON and without ED” and “ON and ED” groups were characterized by less frequent consumption of high-sugar and refined products. Students who rarely consumed meat and related products were found to be less likely to display “ON and ED.” In conclusion, different eating habits shown by people with ON tendency and ED symptoms confirmed the difference between ON and ED. However, the simultaneous displaying of ON and ED leads to the overlapping of specificity of eating habits, which can make the diagnosis based only on the eating habits difficult. Thus, there is still a need for further research involving the use of more sensitive tools that can better identify ON tendency and ED symptoms, as well as DPs.

“…Also, depending on the cut-off at 40-point threshold the ON tendency was higher on all BMI categories despite that there were no signi cant differences between different categories as shown in Table 4. Many previous studies did not reveal differences in the occurrence of ON tendency between BMI categories, for both cut-off point at 35 and 40 points [20,25,31] Clearly, mixed ndings can be shown in the previous studies; the current ndings were in parallel with the results that showed a positive correlation between ON symptomatology and BMI [6,7,20,28,32]. On the contrary, many studies revealed no signi cant differences [5,11,24].…”

“…Few researchers have examined nutrition and dietetic students' incidence of Orthorexia. The results obtained in this research in ORTO-15 test at (35/40) point cut-off thresholds -following the scienti c approach of other literatures [5,10,20,[23][24][25]. We recorded a 72.0% prevalence of ON at cut-off 40-point threshold, there was almost 3-fold decrease in the ON tendency at the 35-point threshold (31.8%).…”

Objective: Orthorexia Nervosa (ON) is defined as an excessive concern in choosing and preparing of meals according to strict rules. The aim of this study was evaluating the threat of orthorexia in a group of students and nutritionists and the tendency toward the presentation of ON behaviorMethods: This cross-sectional study was carried out in July and August of 2019 among 421 nutrition students from six universities, in addition to nutritionists in Jordan. Participants completed questionnaire related to individual characteristics and the ORTO-15 scale. Orthorexia Nervosa (ON) tendency was measured using ORTO-15 questionnaire, referring to different diagnostic thresholds (40/35). P<0.05 was accepted as statistically significant.Results: Orthorexia had 72.0% prevalence in our sample using the 40-point threshold; the figure was reasonably lower with the 35-point threshold (31.8%). Also, ON tendency was significantly affected by BMI categories (p=0.007) and gender (p=0.043) at 35-point threshold. Males have more tendency (39.4%) than females (28.6%) (p=0.029)Conclusion: The results of this study highlight the magnitude of ON in Jordan. Using cut-off at 35 is preferable than cut-off at 40 to identify factors influencing ON. Moreover, ON tendency is affected by gender and BMI and not affected by educational level.
