Sleep disruption as a potential contributor to the worsening of eating disorder pathology during the COVID-19-pandemic

Abstract

AbstractThe acute phase of the COVID-19 pandemic was associated with significant increases in the prevalence and severity of eating disorders (EDs). Studies also highlighted changes to sleep quality and duration in many individuals throughout this period. Although these two phenomena have been examined separately, here we highlight the need to investigate the potential link between these outcomes. Sleep dysregulation and EDs have previously been hypothesized to interact via a positive feedback loop, wherein poor sleep exacerbates ED symptomatology which, in turn, further worsens sleep. Thus, we speculate that the aggravation of sleep disturbances and EDs during COVID-19 lockdowns may have been somewhat interdependent. We further hypothesize that the worsening of depression and anxiety symptomology during the acute phase of the pandemic may have served as an additional mediating variable. Altogether, in our view, these observations highlight a need for future work to examine the possible causal relationship between sleep and ED pathology, which may ultimately lead to improved clinical management of disordered eating.
