Associations between orthorexia, disordered eating, and obsessive-compulsive symptoms: A systematic review and meta-analysis.

Meta-analytic findings showed that ON symptoms are more associated to EDs compared to OCD. Despite the similarities, the nonhigh magnitude of the pooled correlations suggests that ON might be different from pre-existing EDs and OCD. Hence, ON might be treated as a stand-alone ED and included as an emerging syndrome in the DSM classification.
