Tokyo, Oct. 1 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000059246) titled 'The relationship between body image and eating behaviour' on Sept. 30.

Study Type: Interventional

Study Design: Basic Design - Parallel Randomization - Randomized Blinding - Single blind -participants are blinded Control - Placebo

Primary Sponsor: Institute - Tohoku University

Condition: Condition - We will recruit healthy young females and aims to prevent developing anorexia Nervosa and bulimia Nervosa Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - It is known that individuals with anorexia nervosa and bulimia nervosa experience not only disordered eating but also body image disturbances. This study, conducted at the Undergraduate and Graduate Schools of Tohoku University, targeted healthy young women. Through a weekly intervention over one month, it aimed to improve their perception of their own bodies as being overweight. The research sought to elucidate changes in body image disturbances and eating behaviours, along with the underlying brain activity associated with these changes. Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - Participants will perform the task once a week for one month. First, they will view a female 3D image (BMI 8-35, varying in increments of 1) for 3 seconds and respond by pressing a button to indicate either "fat / not fat" or "thin / not thin". Next, participants will view the same image again and respond once more with "fat / not fat" or "thin / not thin" using the button press, but this time they will receive feedback indicating whether their response was correct or incorrect. In the intervention group, the feedback will be manipulated in a way that shifts the judgment threshold toward a 3-BMI-unit higher value (thus, participants in the intervention group will receive more "incorrect" feedback). Whether the threshold should be based on "fat / not fat" or "thin / not thin" will be determined through a preliminary experiment. Interventions/Control_2 - Participants will perform the task once a week for one month. First, they will view a female 3D image (BMI 8-35, varying in increments of 1) for 3 seconds and respond by pressing a button to indicate either "fat / not fat" or "thin / not thin". Next, participants will view the same image again and respond once more with "fat / not fat" or "thin / not thin" using the button press, but this time they will receive feedback indicating whether their response was correct or incorrect. In the control group, the feedback will be provided in a way that does not alter the original judgment threshold. Whether the threshold should be based on "fat / not fat" or "thin / not thin" will be determined through a preliminary experiment.
