Evidence points to a link between gluten-free diet or celiac disease and eating disorders, but not with orthorexia. This study is the first to examine adults with celiac disease in terms of the prevalence of risk of orthorexia. The study included 130 adults diagnosed with celiac disease. The standardized ORTHO-15 questionnaire was used to assess the risk of orthorexia. Cronbach's alpha test was used to determine the reliability of the ORTHO-15 questionnaire. Eating habits of the subjects were assessed using a questionnaire. The effect of celiac disease on diet was assessed on a 5-point scale. A risk of orthorexia was found in 69% of subjects with celiac disease. A statistically significant (p<0.005) positive correlation was observed between age and ORTHO-15 test scores (rho=0.37). In the group with orthorexia risk, meals were more often self-prepared (93.3%) compared to those without orthorexia (80%) (p=0.023). For 80% of those at risk for orthorexia versus 20% without risk, mood was a factor influencing dietary choices (p=0.001). The study observed a strong association between celiac disease and the presence of orthorexia risk. The numerous risk factors for orthorexia suggest the need for holistic care, including nutritional and psychological support among individuals with celiac disease.
