Adolescent girls with AN undergo high levels of stress, which has been shown as risk factor in the development of eating disorders. Widely examined autonomic indices for stress reactivity are heart rate (HR) and heart rate variability (HRV, RR intervals (RRI) in electrocardiogram). The current state of the art concerning HRV as a biomarker for AN show consistently elevated beat-by-beat variance for AN compared to controls. Thus, HRV features may act as a discriminating biomarker and may be used as input feature to different AI methods.


In a pilot study, in cooperation with the University Hospital Erlangen (Department of Child and Adolescent Psychiatry), we will estimate possible biomarkers from HRV measurements in the course of a body confrontation intervention and a whole therapy block (3-4 interventions) in AN patients. For this purpose, an existing pipeline will be extended, which will further refine previous results and thus provide information on stress reactivity in relation to potentially stressful situations alias body confrontations.

Learning Objectives

  • Learn concepts of HRV analysis
  • Develop corresponding algorithms
  • Apply biomarker estimations
