Craving for Food in Virtual Reality Scenarios in Non-Clinical Sample: Analysis of its Relationship with Body Mass Index and Eating Disorder Symptoms.

摘要: Virtual reality (VR) technology has been successfully used to study the influence of specific and contextual food-related cues on emotional, cognitive behavioural responses in patients with eating disorders (ED) healthy controls. Following this research line, present assesses effect reported food craving type (low calorie versus high calorie) presence or absence other people (private social context) VR environments. Relationships between body mass index (BMI) ED symptoms are also explored. Eighty-seven female students were exposed four scenarios presented random order: a low-calorie kitchen, high-calorie restaurant restaurant. After 2 minutes exposure each virtual scenario, was assessed. Repeated measures analyses covariance conducted assess changes following different Time elapsed since last meal introduced as covariate control for produced by deprivation. Correlation hierarchical multiple regression relationship BMI symptoms. Participants experienced higher levels after foods (in both kitchen environments) than foods. Being alone friends had no craving. Overall, neither nor related craving; only significant negative correlation found The results suggest that cue environments is an effective procedure inducing controls may be useful therapeutic tool clinical populations.
