Objective:It was conducted to evaluate the susceptibility to ON(orthorexia nervosa)in the students of the nutrition and dietetics department according to the variables of gender,age and BMI(body massındex).Subjects and Methods:The research covers the students of Marmara University Faculty of Health Sciences,Department of Nutrition and Dietetics in September-October 2017-2018 academic year.The data were collected by survey method.Socio-demographic characteristics and anthropometric measurements of the participants were questioned.EAT-40(Eating Attitude Test),ORTO-15 test and MOCI(Maudsley Obsessive Compulsive Inventory)were used in the study.It was evaluated with SPSS(The Statistical Package for The Social Sciences)21.0 program.Results:205 people participated in the study.EAT-40 scores were found to be≤20 in 94%of the women and 95.2%of the men in the study.The EAT-40 score is≥21 in 6%of women and 4.8%of men in the study(p=0.646>0.05).The ORTO-15 score of 72.3%of women and 71.4%of men is≤40(p=0.934>0.05).EAT-40 average is 10.25±1.10 in underweight.It was found to be 9.21±0.42 in normals and 8.23±0.76 in slightly obese subjects(p=0.758>0.05).ORTO-15 average of those with BMI≤18.49 kg/m2 is 39.59±0.54;Those with 18.50-24.99 kg/m2 were found to be 38.30±0.25 and those with 25.00-29.99 kg/m2 were found to be 39.54±0.75(p=0.098>0.05).As the EAT-40 score increased,the ORTO-15 score decreased.It shows a negative,statistically significant difference between EAT-40 and ORTO-15 scores(p=0.00<0.05).Conclusion:It was concluded that orthorexic tendency is common(72.2%)in nutrition dietetic students,and ON is associated with BMI and EAT-40 scores.In terms of ON,it would be beneficial to conduct comprehensive international studies and determine DSM(Diagnostic and Statistical Manual of Mental Disorders)diagnostic criteria.
