Objective: This study aimed to assess the physiological response of patients with anorexia nervosa (AN) to different types of silhouettes using pupillometry.
Methods: We measured the pupil psychosensory reflex (PSR) of 42 patients with AN and 35 healthy controls in response to standardised body silhouettes and to pictures of their own silhouettes digitally modified to represent different body mass indices (BMI). Perceptual distortion and body dissatisfaction were assessed using Anamorphic Micro Software©.
Background: The persistence of physical exercise in anorexia nervosa (AN) despite underweight and its maintaining factors are poorly understood. The aim of this study was to explore the attitudes toward physical exercise and its effects on emotions, cognitive functioning, and body image perception in patients with AN, and to search for exercise-related endophenotypes of the pathology.
Methods: Physical exercise dependence, quantity, and dysregulation were assessed by the Exercise Dependence Scale (EDS), the Godin Leisure Time Exercise Questionnaire (GLTEQ) and a standardized effort test in 88 patients with AN, 30 unaffected relatives and 89 healthy controls.
