This study aimed to determine whether viewing muscularity-oriented social media content was associated with muscle dysmorphia among a sample of boys and men from Canada and the United States. Data from the Study of Boys and Men (2024; N = 1553) were analyzed. Multiple linear regression analyses were conducted to determine the associations between viewing content with 1) muscular bodies, 2) muscle-building dietary supplements (e.g., whey protein), and 3) muscle-building drugs (e.g., anabolic-androgenic steroids) on social media and probable muscle dysmorphia. Findings revealed strong and positive associations between viewing muscularity-oriented social media content and probable muscle dysmorphia. Specifically, greater frequency of viewing content related to muscular bodies, muscle-building dietary supplements, and muscle-building drugs were all associated with having probable muscle dysmorphia, independent of total time spent on social media. The findings from this study underscore the need for more research to understand the directionality and risks associated with specific social media content among boys and men. Greater media and health literacy is needed for boys and men to support appropriate social media use.
本研究旨在确定在来自加拿大和美国的男孩及男性样本中，浏览以肌肉发达为导向的社交媒体内容是否与肌肉畸形症有关。对男孩和男性研究（2024年；N = 1553）的数据进行了分析。进行了多项线性回归分析，以确定在社交媒体上浏览与1）肌肉发达的身体、2）增肌膳食补充剂（如乳清蛋白）和3）增肌药物（如合成代谢雄激素类固醇）相关的内容与可能的肌肉畸形症之间的关联。研究结果显示，浏览以肌肉发达为导向的社交媒体内容与可能的肌肉畸形症之间存在强烈的正相关。具体而言，浏览与肌肉发达的身体、增肌膳食补充剂和增肌药物相关内容的频率更高，均与可能患有肌肉畸形症有关，且与在社交媒体上花费的总时间无关。本研究的结果强调，需要进行更多研究以了解男孩和男性中与特定社交媒体内容相关的方向性和风险。男孩和男性需要更高的媒体和健康素养，以支持正确使用社交媒体。
