The association between social media addiction and orthorexia nervosa, eating attitudes, and body image among adolescents.

Aim: This study was planned to determine the relationship between social media addiction and orthorexia nervosa (ON), eating attitude and body image among adolescents.
Method: This cross-sectional study was conducted with 1232 high school-going adolescents. Data were collected using the Social Media Addiction Scale for Adolescents, Eating Attitude Test-26 (EAT-26), Body Image Scale (BIS) and ORTO-11 questionnaire.
Results: Social media addiction levels were higher in girls than in boys (p < 0.05). Multiple linear regression analysis showed that a better body image was associated with lower social media addiction scores (β =  - 0.268, p < 0.001). Social media addiction was significantly associated with a greater risk of eating behavior disorders (OR: 1.07, 95% Cl: 1.04-1.10) and ON tendency (OR: 1.02, 95% Cl = 1.00-1.04). Adolescents who stated that they always or often read nutrition-related posts on social media had an increased likelihood of eating behavior disorder risk (OR: 6.77, 95% CI: 3.84-11.94) and ON tendency (OR: 5.49, 95% CI: 3.39-8.88).
Conclusion: This study demonstrated that social media addiction was associated with a higher eating behavior disorder risk, ON tendency and lower body image. Moreover, frequent reading of posts about nutrition on social media was positively associated with ON tendency and eating behavior risk. These results highlight that adolescents should be educated about social media use and its content to minimize the negative effects of constant exposure to unrealistic body images and nutrition-related misinformation and reduce the risk of eating disorders and ON among adolescents. Level of evidence Level V, cross-sectional descriptive study.
