Research has found that high social media use is associated with a greater tendency to compare oneself with others, which in turn may heighten body image concerns and problematic eating behaviours. The aim of this systematic review and meta-analysis was to examine the mean association between online social comparison and body image concerns, eating disorder behaviours and positive body image. Eligible articles published between 2008 and 2024 were searched for in scientific databases. A random-effects meta-analysis was conducted to investigate the direct correlation between social comparison and body image and eating disorder outcomes. Results from 83 studies with 55,440 participants indicated that the weighted average correlation between higher online social comparison and greater body image concerns was significant (r = .454; 95 % CI = 0.409-0.498), as was the correlation between higher social comparison and eating disorder symptoms (r = 0.36; 95 % CI: 0.28-0.43). The mean association between higher social comparison and lower positive body image was also significant (r = -0.242; 95 % CI: -0.329 to -0.155). Meta-regression analysis revealed that the quality of studies, type of social media, country, type of social comparison, percentage of female participants moderated the associations. Findings revealed a moderate size association between higher online social comparison tendencies and worse body image and eating disorder symptoms outcomes, highlighting the need to develop interventions and policies to minimize appearance comparisons on social media.
研究发现，大量使用社交媒体与更倾向于将自己与他人进行比较有关，而这反过来可能会加剧对身体形象的担忧和出现问题的饮食行为。本系统评价和荟萃分析的目的是研究在线社会比较与身体形象担忧、饮食失调行为和积极身体形象之间的平均关联。在科学数据库中检索了2008年至2024年发表的符合条件的文章。进行了随机效应荟萃分析，以研究社会比较与身体形象和饮食失调结果之间的直接相关性。来自83项研究、共55440名参与者的结果表明，较高的在线社会比较与更大的身体形象担忧之间的加权平均相关性显著（r = 0.454；95%置信区间 = 0.409 - 0.498），较高的社会比较与饮食失调症状之间的相关性也显著（r = 0.36；95%置信区间：0.28 - 0.43）。较高的社会比较与较低的积极身体形象之间的平均关联也显著（r = -0.242；95%置信区间：-0.329至-0.155）。荟萃回归分析显示，研究质量、社交媒体类型、国家、社会比较类型、女性参与者百分比对这些关联有调节作用。研究结果显示，较高的在线社会比较倾向与较差的身体形象和饮食失调症状结果之间存在中等程度的关联，这凸显了制定干预措施和政策以尽量减少社交媒体上对外表比较的必要性。
