Social media use and exposure, in particular to highly visual and appearance-focused content, has shown a relationship with poorer body image with small to moderate effect sizes. The aim here was to provide an overview of the theoretical and empirical evidence of the relationships between social media use and body image may vary across individuals. Although evidence exists to support variations in these relationships across different groups, to date, data are scarce and a number of theoretically important groups have largely been overlooked. The available evidence suggests that age may be an important moderating factor of vulnerability to exposure to highly-visual social media content, with younger adolescents most likely to experience negative outcomes. In addition, women and other groups for whom appearance is strongly tied to attractiveness and self-worth may be at heightened risk. Moving forward further research should aim to focus on understanding the relationships between social media use and body image concerns among underrepresented groups, and to expand the focus of to include different aspects of social media use and more sophisticated methodological approaches.

社交媒体的使用和曝光，特别是对高度视觉和以外观为中心的内容，已经显示出与较差的身体形象以及小到中等影响大小的关系。此处的目的是概述社交媒体使用与身体形象之间的关系可能因人而异的理论和经验证据。尽管有证据支持这些关系在不同群体之间存在差异，但迄今为止，数据稀缺，许多理论上重要的群体在很大程度上被忽视了。现有证据表明，年龄可能是暴露于高视觉社交媒体内容的重要调节因素，年轻的青少年最有可能经历负面结果。此外，外表与吸引力和自我价值密切相关的女性和其他群体可能面临更高的风险。进一步的研究应该着眼于了解社交媒体使用与代表性不足群体之间的身体形象问题之间的关系，并将重点扩大到包括社交媒体使用的不同方面和更复杂的方法论方法。
