2-140 - How Inhibitory Control Deficits, Food Reward Processing, and Negative Affect Link to Binge-Eating and Weight Gain in Youth

Session Type: Paper Symposium

Integrative Statement

Binge-eating refers to loss of control while eating high quantities of food in a short time frame. A serious public health concern, binge-eating is highly comorbid with other psychological disorders and increases risk for obesity and related health concerns. Several theories regarding binge-eating suggest that inhibitory control, reward sensitivity, and negative affect may underlie the behavior, yet these links remain unclear.

This symposium will present research suggesting several perspectives on how inhibitory control and negative affect contribute to binge-eating in childhood and adolescence. The first presenter will provide a broad developmental frame for binge-eating symptoms by identifying how growth in ADHD symptoms, which are closely associated with low inhibitory control, and depression symptoms in childhood and adolescence contribute to binge-eating symptoms. Results demonstrated that growth in ADHD symptoms in childhood and adolescence predicted binge-eating, whereas growth in depression symptoms did not. The second presenter will describe how executive functioning, which governs inhibitory control, differs between children with and without binge-eating behaviors. These differences may create further vulnerability for binge-eating in adolescence, particularly for girls, as they face puberty, increased sensitivity to reward, and increased risk for depression. The third presenter will describe research demonstrating that increased reward sensitivity to palatable food predicted weight gain among adolescent girls three years later. Finally, the fourth presenter will discuss findings demonstrating time-ordered relations among onset of puberty, negative affect and urgency, and binge-eating. These findings together describe how inhibitory control deficits, sensitivity to food reward, and negative affect contribute to binge-eating for youth.
