Social media use represents an emerging area of interest in relation to body image and disordered eating. Previous research has demonstrated social media use may be related to eating disorder risk, an increase in body image concerns, bulimic symptoms, and restricted eating. Orthorexia Nervosa (ON), a disordered eating pattern focused on the purity/quality of food, needs further investigation within the social media context. The current study examined whether young adult women’s social media use was associated with objectified body consciousness and orthorexia nervosa symptoms. Social media use, both active and passive, was significantly correlated with body consciousness (body surveillance and body shame) but was not significantly correlated with orthorexia nervosa symptoms. However, in the regression model, only objectified body consciousness, not social media use, significantly predicted ON tendencies. Understanding the impact of social media and body consciousness on ON behaviors may have implications for young women’s mental health, as well as eating disorder programs and recovery.
