Social media use is associated with body image concerns, disordered eating and body change behaviors in adolescents. This study aimed to examine these relationships within a biopsychosocial framework and test an integrated model. A sample of 681 adolescents (49% female), mean age = 12.76 years (SD = 0.74), completed a questionnaire assessing social media use, depression, self-esteem, body mass index, social media and muscular ideal internalization, appearance comparison, body dissatisfaction, disordered eating, and muscle-building behaviors. Path analysis was used to test the hypothetical model, which after modification revealed good fit to the data, although gender differences emerged. The findings suggest that biopsychosocial frameworks are useful for conceptualizing relationships between social media use and body image, eating, and muscle building outcomes.
社交媒体的使用与青少年的身体意象问题、饮食失调和身体改变行为有关。本研究旨在从生物心理社会框架内检验这些关系，并测试一个综合模型。一个由 681 名青少年（49%为女性）组成的样本，平均年龄为 12.76 岁（SD=0.74），完成了一份问卷，评估了社交媒体使用、抑郁、自尊、体重指数、社交媒体和肌肉理想内化、外貌比较、身体不满、饮食失调和肌肉锻炼行为。路径分析用于测试假设模型，经过修正后，该模型与数据拟合良好，尽管存在性别差异。研究结果表明，生物心理社会框架对于理解社交媒体使用与身体意象、饮食和肌肉锻炼结果之间的关系是有用的。
