Eating disorders are widespread illnesses with significant impact. There is growing concern about how those at risk of eating disorders overuse online resources to their detriment. We conducted a pre-registered systematic review and meta-analysis of studies examining Problematic Usage of the Internet (PUI) and eating disorder and related psychopathology. The meta-analysis comprised n = 32,295 participants, in which PUI was correlated with significant eating disorder general psychopathology Pearson r = 0.22 (s.e. = 0.04, p < 0.001), body dissatisfaction r = 0.16 (s.e. = 0.02, p < 0.001), drive-for-thinness r = 0.16 (s.e. = 0.04, p < 0.001) and dietary restraint r = 0.18 (s.e. = 0.03). Effects were not moderated by gender, PUI facet or study quality. Results are in support of PUI impacting on eating disorder symptoms; males may be equally vulnerable to these potential effects. Prospective and experimental studies in the field suggest that small but significant effects exist and may have accumulative influence over time and across all age groups. Those findings are important to expand our understanding of PUI as a multifaceted concept and its impact on multiple levels of ascertainment of eating disorder and related psychopathology.
进食障碍是一种广泛存在且具有重大影响的疾病。人们越来越关注那些有进食障碍风险的人如何过度使用在线资源对其造成损害。我们对研究中检查互联网问题使用（Problematic Usage of the Internet，PUI）和进食障碍及相关精神病理学的研究进行了预先注册的系统回顾和荟萃分析。荟萃分析包括 n = 32295 名参与者，其中 PUI 与显著的进食障碍一般精神病理学呈显著相关（Pearson r = 0.22，标准误 = 0.04，p < 0.001）、与身体不满（r = 0.16，标准误 = 0.02，p < 0.001）、与瘦身欲望（r = 0.16，标准误 = 0.04，p < 0.001）和饮食克制（r = 0.18，标准误 = 0.03）呈显著相关。性别、PUI 方面或研究质量并不能调节这些结果。结果支持 PUI 对进食障碍症状的影响；男性可能同样容易受到这些潜在影响的影响。该领域的前瞻性和实验研究表明，确实存在着较小但显著的影响，并且可能随着时间的推移和在所有年龄组中积累影响。这些发现对于我们扩大对 PUI 的理解很重要，因为它是一个多方面的概念，其对进食障碍和相关精神病理学的多个层面的确定都有影响。
