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 (14.5 ± 2.3 years; 86.8% female; BMI-z 1.7 ± .73) with (n = 47) and without (n = 29) reported LOC eating. Following a breakfast to reduce hunger, youth participated in a computerized visual probe task of sustained attention that assessed reaction time to pairs of pictures consisting of high palatable foods, low palatable foods, and neutral household objects. Although sustained attentional bias did not differ by LOC eating presence and was unrelated to body weight, a two-way interaction between BMI-z and LOC eating was observed (p = .01), such that only among youth with LOC eating, attentional bias toward high palatable foods versus neutral objects was positively associated with BMI-z. These findings suggest that LOC eating and body weight interact in their association with attentional bias to highly palatable foods cues, and may partially explain the mixed literature linking attentional bias to food cues with excess body weight.
新出现的数据表明,患有暴饮暴食症的成年人可能会对高适口性食物表现出注意力偏向,这可能会促进致胖的饮食模式和体重过度增加。然而,尚不清楚有失控(LOC)饮食行为的青少年在多大程度上表现出类似的偏向。因此,我们研究了76名青少年(14.5±2.3岁;86.8%为女性;BMI-z为1.7±0.73),其中报告有LOC饮食行为的有47人,无LOC饮食行为的有29人。在食用早餐以减轻饥饿感后,青少年参与了一项持续注意力的计算机视觉探测任务,该任务评估了他们对由高适口性食物、低适口性食物和中性家居物品组成的图片对的反应时间。尽管持续注意力偏向在有无LOC饮食行为方面没有差异,且与体重无关,但观察到BMI-z和LOC饮食行为之间存在双向交互作用(p = 0.01),即仅在有LOC饮食行为的青少年中,对高适口性食物与中性物品的注意力偏向与BMI-z呈正相关。这些发现表明,LOC饮食行为和体重在与对高适口性食物线索的注意力偏向的关联中相互作用,并且可能部分解释了将对食物线索的注意力偏向与超重联系起来的文献中的矛盾之处。
