本研究旨在探讨青少年自我报告的情绪化进食分数与额边缘脑对美味的反应之间的关系。参与者包括162名青少年（平均BMI百分位数= 52.7，范围3-90）。参与者完成了一项评估情绪化进食的自我报告调查，并接受了功能性磁共振成像（fMRI），同时观看了随后提供巧克力奶昔或控制口味的图片，并接受了相应的味道。结果显示，情绪化进食分数和大脑对收到奶昔的预期反应之间没有显着关系。在响应奶昔的味道接收，情绪化进食分数呈负相关的激活在右侧丘脑，左侧丘脑和眶额皮质，和双边壳核和尾状核。在控制体重指数和体脂百分比后，这些发现仍然显着。目前的研究结果进行了讨论的背景下，减少奖励激活可口的口味接收肥胖的成年人和青少年的调查结果。
This study examined the relation between self-reported emotional eating scores and frontolimbic brain response to palatable taste in adolescents. Participants included 162 adolescents (Mean BMI percentile = 52.7, range 3–90). Participants completed a selfreport survey assessing emotional eating and underwent functional magnetic resonance imaging (fMRI) while viewing pictures signaling subsequent delivery of a chocolate milkshake or a control taste and receiving the corresponding taste. Results revealed no significant relation between emotional eating scores and brain response to anticipation of receipt of milkshake. In response to milkshake taste receipt, emotional eating scores were negatively related to activation in the right thalamus, the left insula and orbitofrontal cortex, and bilateral putamen and caudate. These findings remained significant after controlling for body mass index and body fat percentage. The current results are discussed in the context of findings of reduced reward activation to palatable taste receipt in obese adults and adolescents.
