Since the rising global obesity rate and increasingly stringent standards for the ideal body shape constitute a growing contradiction, restrictive eating behavior has become a common weight control strategy among the general public, especially adolescents, leading to body image disturbance and identity crisis, which is a pressing real-world problem that requires urgent attention. A questionnaire survey was conducted among 934 adolescents. The results showed that: (1) Passive social media use significantly and positively predicted restrictive eating behavior in adolescents; (2) Self-objectification and upward social comparison served as both independent and chain mediators between passive social media use and restrictive eating behavior; (3) There is also significant gender difference in the chain mediating effect. The study reveals the psychological mechanisms and gender difference underlying the relationship between social media and disordered eating behaviors in adolescents, providing evidence for targeted prevention and precise intervention.
