This observational study investigates the prevalence and severity of disordered eating behaviors in adolescents aged 11-17 years with celiac disease. Participants complete validated self-report questionnaires (Youth Eating Disorder Examination Questionnaire, YEDE-Q, and Parent Eating Disorder Examination Questionnaire, PEDE-Q) and a structured clinical form. A healthy control group, matched by age and sex, is included for comparison. A longitudinal sub-cohort diagnosed with celiac disease \<6 months prior will be followed at 6, 12, and 24 months to evaluate changes in eating psychopathology and associated clinical variables.
