Official title
Predicting Binge and Purge Episodes From Passive and Active Apple Watch Data Using a Dynamical Systems Approach
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The Binge Eating Genetics Initiative (BEGIN) is an observational study where individuals with binge-eating disorder (BED) or bulimia nervosa (BN) complete assessments about eating disorder history, current disordered eating behavior, and mood. Participants also provide active data on binge eating, purging, nutrition, and cognitions using Recovery Record on the Apple Watch. Passive sensor data are collected via native applications over a 30-day period in 1000 individuals with BED or BN. Investigators will combine longitudinal passive (Apple Watch) and active (Recovery Record) data to predict when patients are at high risk of binge eating or purging. Results will enable the deployment of real-time, in-the-moment, personalized signaling of impending binge or purge episodes that will interrupt automatic behaviors and empower patients to exert control over binge eating and purging by engaging in therapeutic alternatives.
