Healthy orthorexia, orthorexia nervosa, and personality traits in a community sample in Turkey.

Objective: Orthorexia nervosa is an eating disorder characterized by a rigid preoccupation with a perceived healthy diet. However, little is known about healthy orthorexia compared to orthorexia nervosa. The current study examined the relationship between healthy orthorexia and orthorexia nervosa and personality traits in a Turkish sample.

Methods: Three hundred fifty participants from a community sample aged 18-65 were included in the study. Participants completed a sociodemographic data collection form, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Teruel Orthorexia Scale (TOS), and the 10-Item Personality Inventory (TIPI).

Results: The frequency of healthy orthorexia was 32.3% and orthorexia nervosa was 10.2%. There were no differences between genders regarding healthy orthorexia and orthorexia nervosa scores. Healthy orthorexia symptoms were negatively correlated with depression and anxiety (r = -0.11 and r = -0.20, respectively, P < .05), while they were positively correlated with agreeableness (r = 0.17), conscientiousness (r = 0.14), and extraversion (r = 0.15). Orthorexia nervosa symptoms were positively associated with anxiety (r = 0.12), depression (r = 0.10), and healthy orthorexia (r = 0.55). Hierarchical regression analyses demonstrated that depression was negatively associated with healthy orthorexia symptoms, explaining 4% of the variance. The agreeableness trait was positively associated with healthy orthorexia symptoms, explaining 4% of the variance. However, no specific personality trait was associated with orthorexia nervosa symptoms.

Conclusion: To our knowledge, the present study is the first to examine the relationships between personality traits, healthy orthorexia, and orthorexia nervosa symptoms in a Turkish sample. Sociocultural factors may be important for understanding orthorexia nervosa and healthy eating behaviors in this population.
