Saturday, November 16, 2024
2:30 PM – 4:00 PM EST
Location: Grand Ballroom E, Level 5, Downtown Marriott
CE: 1.5

Keywords: Eating, Sleep,
Level of Familiarity: Basic to moderate
Recommended Readings: Allison, K. C., Spaeth, A., & Hopkins, C. M. (2016). Sleep and eating disorders. Current psychiatry reports, 18, 1-8.,   Cooper, A. R., Loeb, K. L., & McGlinchey, E. L. (2020). Sleep and eating disorders: Current research and future directions. Current Opinion in Psychology, 34, 89-94.,   Manasse, S. M., Lampe, E. W., Gillikin, L., Trainor, C. M., Abber, S. R., Fitzpatrick, B., ... & Juarascio, A. S. (2022). An examination of daily sleep characteristics and subsequent eating disorder behavior among individuals with binge-spectrum eating disorders. Eating and Weight Disorders-Studies on Anorexia, Bulimia and Obesity, 27(8), 3743-3749.,   ,  

A growing body of research has demonstrated that sleep dysregulation (e.g., difficulties falling or staying asleep, circadian misalignment of sleep) is not only common among individuals with eating disorders (EDs; Allison et al., 2016; Kim et al., 2010) but also uniquely contributes to biopsychosocial impairment in this population (Cooper et al., 2020). For example, sleep dysregulation is associated with hypertension (Li et al., 2021), diabetes (nothaisintawee et al., 2016), and overall reduced well-being (Kyle et al., 2010). Sleep dysregulation is also a well-established risk-factor for psychopathology such as depression, anxiety, post-traumatic stress disorder, and greater severity of ED behaviors (Hertenstein et al., 2019; Li et al., 2016; Manasse et al., 2022; Thun et al., 2019). Sleep dysregulation has also been linked with poorer treatment outcomes across the diagnostic spectrum e.g., Babson et al., 2013; Chen et al., 2017; Manber et al., 2008; Ohayon and Roth, 2003; Short et al., 2017, including among individuals with EDs (Manasse et al., under review). As such, understanding the role of sleep dysregulation among individuals with EDs is critical for the development of targeted interventions which can improve both sleep dysregulation and ED pathology. However, literature in this area has been impaired by reliance on retrospective self-report of both eating and sleep over long periods (e.g., weeks to months), limiting our ability to identify specific, modifiable targets for intervention. On a shorter timescale, research in this area has yet to explore within-day associations of sleep dysregulation with next-day ED behaviors, within-person differences in associations between sleep and ED pathology, and bridge symptoms linking sleep dysregulation and ED behavior engagement. In this symposium, five researchers will present novel findings leveraging advanced technology and data analytics to address these important questions. First, Dr. Christina Ralph-Nearman will present findings from a network analysis on bridge symptoms linking sleep dysregulation and ED pathology. Second, Dr. Kara Christensen-Pacella will use ecological momentary assessment (EMA) to untangle complex relationships between sleep quality and ED behaviors. Third, Elizabeth Lampe will present findings demonstrating that pre-binge elevations in negative affect may form an explanatory link between nightly sleep dysregulation and next-day binge eating. Fourth, Dr. Stephanie Manasse will use both EMA and passive sensor measurement of sleep to identify predictors of next-day binge eating and overeating in an adolescent sample. Finally, Shruti Kinkel-Ram will present within-person associations between sleep dysregulation and suicidal ideation among ED patients at a higher level of care. Dr. Kelly Allison, an expert in the intersection between EDs and sleep dysregulation (Allison et al., 2016) will serve as the discussant for the symposium.

Learning Objectives:

At the end of this session, the learner will be able to:
  1. Discuss relationships between sleep and eating disorder behaviors on a day-to-day level.
  2. Explain within-person relationships between changes in sleep and eating disorder behaviors.
  3. Discuss the implementation of EMA and sensors to measure sleep and eating disorder symptoms.
  4. Identify the role of sleep processes in maintaining broader disordered eating pathology.
  5. Identify bridge symptoms linking sleep disturbance and eating disorders.
