Body dysmorphic disorder (BDD) has been consistently linked with eating disorders, however studies that stratify associations between BDD in subjects with and without eating disorder symptomology are sparse. It was, therefore, the aim of this study to assess correlates of BDD (including social media use, motivations for exercise, exercise addiction, and sexuality) stratified by eating disorder symptomology.
Cross-sectional study of 1665 health club users recruited online completed a battery of surveys. BDD prevalence rates were calculated and logistic regression models were created in two sub-samples: indicated or no-indicated eating disorder symptomology.
The key findings showed the prevalence of BDD in participants with indicated-eating disorder symptomology was significantly higher than in participants without indicated-eating disorder symptomology, yielding an odds ratio of 12.23. Furthermore, several correlates were associated with BDD only participants with an absence of eating disorder symptomology (gender, BMI, exercise addiction, exercising for mood improvement, attractiveness and tone), with others being significantly associated with BDD in participants in the presence of indicated eating disorders symptomology (exercising for health and enjoyment, relationship status, and ethnicity).
This study provides more evidence of the complex relationship that exists between BDD and eating disorders. Furthermore, it is recommended that practitioners working with BDD subjects should screen for eating disorders due to the high morbidity associated with eating disorders.
Level III: case-control analytic study.
躯体变形障碍（BDD）一直与饮食失调有关，但对有和无饮食障碍症状的受试者之间 BDD 关联进行分层研究的研究很少。因此，本研究旨在评估根据饮食障碍症状分层的 BDD 的相关因素（包括社交媒体使用、运动动机、运动成瘾和性行为）。
对在线招募的 1665 名健身俱乐部使用者进行横断面研究，完成了一系列调查。计算了 BDD 的患病率，并在两个子样本中创建了逻辑回归模型：有或无饮食障碍症状。
主要发现显示，有饮食障碍症状的参与者中 BDD 的患病率明显高于无饮食障碍症状的参与者，优势比为 12.23。此外，一些相关因素仅与无饮食障碍症状的 BDD 参与者相关（性别、BMI、运动成瘾、为改善情绪而运动、吸引力和音调），而其他因素与有饮食障碍症状的参与者的 BDD 显著相关（为健康和享受而运动、关系状况和种族）。
本研究提供了更多证据表明 BDD 与饮食失调之间存在复杂的关系。此外，建议与 BDD 患者一起工作的从业者应筛查饮食障碍，因为饮食障碍与高发病率有关。
