To assess whether attentional bias to food cues and appetitive traits are independently and interactively associated with adiposity in adolescents.
Eighty-five adolescents, 14-17-years had their attentional bias to food images measured in a sated state by computing eye tracking measures of attention (first fixation duration, cumulative fixation duration) to food and control distractor images that bordered a computer game. Parents reported adolescent appetitive traits including the food approach domains of enjoyment of food, food responsiveness, emotional overeating, and the food avoidance domains of satiety responsiveness and emotional overeating through the Children's Eating Behavior Questionnaire.
First fixation bias to food cues was positively associated with enjoyment of food, and negatively associated with satiety responsiveness. In a series of regression models adjusted for relevant covariates, first fixation bias to food cues (β = 0.83, p = 0.007), higher food responsiveness (β = 0.74, p < 0.001), higher emotional overeating (β = 0.51, p = 0.002), and a composite appetite score (β = 1.42, p < 0.001) were each significantly associated with greater BMI z-scores. In models assessing the interactive effects between attentional bias and appetitive traits, higher first fixation bias to food cues interacted synergistically with food responsiveness and emotional overeating in relation to BMI z-score. A synergistic interaction between first fixation bias to food cues and the composite appetite score in relation to BMI z-score was also observed.
Individuals with high attentional bias to food cues and obesogenic appetitive traits may be particularly susceptible to weight gain.
评估青少年对食物线索的注意力偏向和食欲特征是否与肥胖独立且相互作用。
85 名 14-17 岁的青少年在饱腹状态下通过计算对食物和控制分心物图像的眼动注意指标（首次注视持续时间、累积注视持续时间）来测量对食物图像的注意力偏向。父母通过儿童饮食行为问卷报告青少年的食欲特征，包括对食物的享受、食物反应性、情绪性暴食和饱腹感反应性、情绪性暴食的食物回避等领域。
对食物线索的首次注视偏向与对食物的享受呈正相关，与饱腹感反应呈负相关。在一系列调整了相关协变量的回归模型中，对食物线索的首次注视偏向（β=0.83，p=0.007）、更高的食物反应性（β=0.74，p<0.001）、更高的情绪性暴食（β=0.51，p=0.002）和食欲综合评分（β=1.42，p<0.001）均与更大的 BMI z 评分显著相关。在评估注意力偏向和食欲特征之间的交互作用的模型中，更高的对食物线索的首次注视偏向与食物反应性和情绪性暴食协同作用，与 BMI z 评分相关。对食物线索的首次注视偏向与食欲综合评分之间也观察到与 BMI z 评分相关的协同交互作用。
对食物线索注意力偏向较高且具有肥胖相关食欲特征的个体可能特别容易体重增加。
