Research shows inconsistent findings about the link between muscle dysmorphia (MD) and eating disorder (ED) symptomatology. The aim of this study is to synthesize the scientific evidence available on this topic, the researchers conducted a systematic review and meta-analysis.
The literature search enabled us to identify 39 published articles, which provided 36 independent estimations of the correlation between the two variables.
Our analysis found a positive association between MD and ED symptoms ( = .36; 95% CI = 0.30, 0.41). Moderator analyses showed that the type of sample and the tools for assessing MD and ED were statistically associated with the MD-ED effect sizes. The methodological quality of the studies exhibited a positive, statistically significant association with the MD-ED effect sizes.
Higher levels of MD were related to greater ED symptomatology, but several study characteristics may moderate the association between the two variables. In this study, we discuss limitations and implications for clinical practice and future research.
研究表明，肌肉变形障碍（MD）与饮食障碍（ED）症状之间的关联存在不一致的发现。本研究旨在综合该主题的现有科学证据，研究人员进行了系统回顾和荟萃分析。
文献检索使我们能够识别出 39 篇已发表的文章，这些文章提供了两个变量之间相关性的 36 个独立估计值。
我们的分析发现 MD 与 ED 症状之间存在正相关（ = .36；95% CI = 0.30，0.41）。 调节分析表明，样本类型和评估 MD 和 ED 的工具与 MD-ED 效应大小具有统计学关联。研究的方法学质量与 MD-ED 效应大小呈正相关，且具有统计学意义。
更高水平的 MD 与更大的 ED 症状有关，但有几个研究特征可能会调节两个变量之间的关联。在这项研究中，我们讨论了局限性以及对临床实践和未来研究的影响。
