Anxiety connects social media use to food and alcohol disturbance and disordered eating when social support is low

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. •Social media use (SMU) influences food and alcohol disturbance (FAD) through anxiety•More SMU is also related to more general disordered eating behaviors through anxiety•SMU is unrelated to FAD or disordered eating through anxiety at higher social support
