Last edited: 4/16/2026

Overview

Orthorexia nervosa is characterized by an obsessive preoccupation with eating healthy food to the detriment of overall well-being and social functioning 1.

Diagnosis

  • Key Diagnostic Criteria: Scoring above a certain threshold on the ORTO-15 questionnaire indicates orthorexia nervosa 1.
  • Recommended Tests: Use of SF-36 for assessing general health status and IPAQ for evaluating physical activity levels 1.
  • Grading: No specific grading system mentioned; diagnosis relies on questionnaire scores 1.
  • Management

  • First-Line Treatments: Cognitive-behavioral therapy (CBT) is implied as a primary approach, though specific details are not provided in the abstract 1.
  • Adjunctive Treatments: Nutritional counseling may be beneficial but is not explicitly detailed in the provided abstract 1.
  • Special Populations

  • Exercise Science Students: Higher prevalence of orthorexia nervosa observed compared to business students, with notable impact on bodily pain and physical activity levels 1.
  • Key Recommendations

  • Screen exercise science students for orthorexia nervosa using the ORTO-15 questionnaire due to higher prevalence 1 (Evidence: Moderate).
  • Consider cognitive-behavioral interventions for individuals diagnosed with orthorexia nervosa, particularly in populations with high physical activity engagement 1 (Evidence: Expert opinion).
  • Monitor and address bodily pain and physical activity levels in students with orthorexia nervosa, as these factors may correlate with symptom severity 1 (Evidence: Moderate).
