Maladaptive Restrictive Food Choice Behavior in Adolescents With Anorexia Nervosa

Area of Science:

• Neuroscience
• Psychology
• Clinical Research

Background:

• Anorexia nervosa (AN) involves persistent food intake restriction, primarily studied in adults.
• Adolescent AN treatment outcomes are more favorable, necessitating research into their specific decision-making processes.

Purpose of the Study:

• To investigate maladaptive food choice behavior in adolescents with AN.
• To determine if adolescents with AN exhibit the same decision-making processes as adults.

Main Methods:

• A computer-based food choice task was administered to adolescents with AN (n=42) and age-matched controls (n=42).
• Participants rated food images for healthiness and tastiness before making choices between food items.

Main Results:

• Adolescents with AN selected high-fat foods less often than controls.
• Food choices in adolescents with AN were more influenced by perceived healthiness and less by tastiness compared to controls.
• Adolescents with AN reported lower tastiness ratings and higher restrictive eating habit strength, though the latter did not correlate with food choices.

Conclusions:

• Adolescents with AN exhibit similar maladaptive food choice behavior to adults, characterized by persistent restriction of high-fat foods.
• Perceived healthiness significantly influences food choices in adolescents with AN more than in controls.
