Previous research has shown positive associations between SCRD and eating disorders, however, the direction of association is still unclear. Research focusing on clinical eating disorder populations can only provide limited insights into the causal relationship between both health concerns, as retrospective assessments are impacted by recollection bias regarding which problem presented first. Therefore, the present review will focus on a general population sample. Overall, this review aims to provide a comprehensive and systematic review of existing research within this field, to gain a better understanding of relevant study findings, their quality, and scope. Additionally, the present review will aim to investigate the causal relationship between disordered sleep and disordered eating in the general population by including longitudinal research designs.
