This study was planned to determine the relationship between social media addiction and orthorexia nervosa (ON), eating attitude and body image among adolescents.
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.
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).
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.
本研究旨在确定青少年群体中社交媒体成瘾与正食癖、饮食态度和身体意象之间的关系。
本横断面研究对1232名高中生进行。使用青少年社交媒体成瘾量表、饮食态度测试-26（EAT-26）、身体意象量表（BIS）和ORTO-11问卷收集数据。
女孩的社交媒体成瘾水平高于男孩（p < 0.05）。多元线性回归分析表明，更好的身体意象与较低的社交媒体成瘾得分相关（β = -0.268，p < 0.001）。社交媒体成瘾与饮食行为障碍风险增加（比值比：1.07，95%置信区间：1.04 - 1.10）和正食癖倾向（比值比：1.02，95%置信区间 = 1.00 - 1.04）显著相关。表示总是或经常在社交媒体上阅读营养相关帖子的青少年，饮食行为障碍风险增加的可能性更大（比值比：6.77，95%置信区间：3.84 - 11.94），正食癖倾向增加的可能性更大（比值比：5.49，95%置信区间：3.39 - 8.88）。
本研究表明，社交媒体成瘾与更高的饮食行为障碍风险、正食癖倾向和更低的身体意象相关。此外，频繁在社交媒体上阅读营养相关帖子与正食癖倾向和饮食行为风险呈正相关。这些结果凸显了应对青少年进行社交媒体使用及其内容方面的教育，以尽量减少持续接触不切实际的身体意象和营养相关错误信息的负面影响，并降低青少年饮食失调和正食癖的风险。证据水平：V级，横断面描述性研究。
