Neural underpinnings of threat bias in relation to loss-of-control eating behaviors among adolescent girls with high weight.

ABSTRACT:

Introduction

Loss-of-control (LOC) eating, a key feature of binge-eating disorder, may relate attentional bias (AB) to highly salient interpersonal stimuli. The current pilot study used magnetoencephalography (MEG) to explore neural features of AB to socially threatening cues in adolescent girls with and without LOC-eating.

Methods

Girls (12-17 years old) with overweight or obesity (BMI >85th percentile) completed an AB measure on an affective dot-probe AB task during MEG and evoked neural responses to angry or happy (vs. neutral) face cues were captured. A laboratory test meal paradigm measured energy intake and macronutrient consumption patterns.

Results

Girls (N = 34; M_age = 15.5 ± 1.5 years; BMI-z = 1.7 ± 0.4) showed a blunted evoke
