This study aimed to determine whether the internalization of body ideals and sociocultural pressures to adhere to body ideals are associated with a greater likelihood of having probable muscle dysmorphia. Cross-sectional data from 1553 boys and men ages 15-35 from Canada and the United States were used. Multiple logistic regression analyses determined the association between the internalization of three body ideals, sociocultural pressures to adhere to body ideals from four sources, and having probable muscle dysmorphia. The odds of having probable muscle dysmorphia were significantly greater for those who internalized the muscular ideal and general attractiveness ideal. Conversely, endorsing the thin/low body fat ideal was significantly associated with lower odds of having probable muscle dysmorphia. Pressure from peers, but no other sources, showed a significant association with greater odds of having probable muscle dysmorphia. Findings expand prior research by investigating correlates of muscle dysmorphia versus muscle dysmorphia symptomatology. The strong association with internalization of the general attractiveness ideal provides new insights into how overall appearance may be highly relevant for boys and men with muscle dysmorphia, warranting future investigation.
本研究旨在确定身体理想的内化以及坚持身体理想的社会文化压力是否与患可能的肌肉畸形症的可能性增加有关。使用了来自加拿大和美国的1553名年龄在15至35岁之间的男孩和男性的横断面数据。多项逻辑回归分析确定了三种身体理想的内化、来自四个来源的坚持身体理想的社会文化压力与患可能的肌肉畸形症之间的关联。对于那些内化了肌肉理想和一般吸引力理想的人来说，患可能的肌肉畸形症的几率显著更高。相反，认可瘦/低体脂理想与患可能的肌肉畸形症的几率显著降低有关。来自同伴的压力，但不是其他来源的压力，与患可能的肌肉畸形症的几率更高有显著关联。研究结果通过调查肌肉畸形症与肌肉畸形症症状的相关因素扩展了先前的研究。与一般吸引力理想的内化之间的强烈关联为整体外貌对于患有肌肉畸形症的男孩和男性可能高度相关提供了新的见解，值得未来进行调查。
