Neural activation during anticipated peer evaluation and laboratory meal intake in overweight girls with and without loss of control eating.

The interpersonal model of loss of control (LOC) eating proposes that socially distressing situations lead to anxious states that trigger excessive food consumption. Self-reports support these links, but the neurobiological underpinnings of these relationships remain unclear. We therefore examined brain regions associated with anxiety in relation to LOC eating and energy intake in the laboratory.

Attentional bias to food cues in youth with loss of control eating.

Emerging data indicate that adults with binge eating may exhibit an attentional bias toward highly palatable foods, which may promote obesogenic eating patterns and excess weight gain. However, it is unknown to what extent youth with loss of control (LOC) eating display a similar bias. We therefore studied 76 youth (14.

Puberty and the manifestations of loss of control eating in children and adolescents.

Objective: We investigated the manifestations of pediatric loss of control (LOC) eating at different stages of pubertal development.

Method: Participants were a nonclinical sample of 468 youth (8-17 years). Physical examination determined pubertal stage.

Depressive symptoms and observed eating in youth.

Depressive symptoms in youth may be a risk factor for obesity, with altered eating behaviors as one possible mechanism. We tested whether depressive symptoms were associated with observed eating patterns expected to promote excessive weight gain in two separate samples. In Study 1, 228 non-treatment-seeking youth, ages 12-17y (15.

Self-efficacy beliefs and eating behavior in adolescent girls at-risk for excess weight gain and binge eating disorder.

Objective: To examine the relationship between self-related agency beliefs and observed eating behavior in adolescent girls with loss of control (LOC) eating.

Method: One-hundred eleven adolescent girls (14.5 ± 1.

Pre-meal affective state and laboratory test meal intake in adolescent girls with loss of control eating.

Loss of control eating confers risk for excess weight gain and exacerbated disordered eating. Affect theory proposes that loss of control eating is used to cope with negative mood states. Self-report data suggest that negative affect may contribute to the etiology of loss of control eating, but this theory has not been well-tested using laboratory paradigms.
