A systematic review published in the Journal of Eating Disorders finds that social media use is consistently associated with eating disorder symptoms and diagnoses in adults aged 18 to 30.
Researchers analyzed seven studies from major databases. Six of those studies reported a positive link between online engagement and conditions like anorexia and bulimia.
Appearance-focused content, including so-called 'thinspiration' and 'fitspiration,' was particularly harmful. Problematic social media use patterns also correlated with more severe symptoms.
Scientists caution the review does not prove causation due to a small number of studies and varied methods. However, the evidence points to social media as a potential risk factor.
