Food and alcohol disturbance (FAD) is an understudied form of disordered eating, in which the consumption of calories is restricted in preparation for drinking alcohol. Guided by previous literature, the present study examined the direct, indirect, and interactive relationships between social media use, anxiety, social support, FAD, and disordered eating among young adults. Recruited from a large southwestern public university, the sample included 679 undergraduate students who completed an online survey in spring of 2022 and who indicated that they consume alcohol and are 18 to 29 years old. Two moderated mediation analyses assessed the indirect effects of anxiety on the relationships between social media use with FAD and disordered eating, and the conditional contribution of social support. Results indicated that social media use was related to disordered eating both directly and indirectly through anxiety, but it was only related to FAD through anxiety. Furthermore, indirect effects connecting social media use to FAD and disordered eating were conditional upon social support. Our findings suggest FAD and disordered eating may be coping mechanisms for anxiety stemming from social media exposure, though these associations appear to be attenuated when social support is high. As such, these findings may be relevant for shaping future intervention and prevention efforts for emerging adults experiencing FAD and disordered eating.
饮食紊乱（FAD）是一种未被充分研究的进食障碍形式，其特征是在饮酒前限制卡路里摄入。本研究以先前的文献为指导，考察了社交媒体使用、焦虑、社会支持、FAD 和年轻人饮食障碍之间的直接、间接和交互关系。该研究从一所位于美国西南部的大型公立大学招募了 679 名本科生，他们在 2022 年春季完成了一项在线调查，表明他们饮酒且年龄在 18 至 29 岁之间。两项调节中介分析评估了焦虑对社交媒体使用与 FAD 和饮食障碍之间关系的间接影响，以及社会支持的条件贡献。结果表明，社交媒体使用与饮食障碍既有直接关系，也通过焦虑产生间接关系，但仅通过焦虑与 FAD 产生关联。此外，将社交媒体使用与 FAD 和饮食障碍联系起来的间接效应取决于社会支持。我们的研究结果表明，FAD 和饮食障碍可能是社交媒体暴露引起焦虑的应对机制，但当社会支持较高时，这些关联似乎会减弱。因此，这些发现可能与为正在经历 FAD 和饮食障碍的年轻人制定未来的干预和预防措施有关。
