动物研究表明，在慢性应激动物中，HPA轴应激反应迟钝与应激诱导的食物摄入增加之间存在关系。这种关系可以潜在地解释人类情绪化进食的潜在机制。然而，还没有研究通过实验测试高情绪进食者和低情绪进食者的应激诱导的皮质醇反应和急性食物摄入之间的关系。我们研究了这些影响，在46名女学生预选的基础上，极高（HEE）或极低（LEE）分数的情绪饮食问卷。使用受试者内设计，我们测量了控制或压力任务（特里尔社会压力测试）后的实际食物摄入量的差异。HEE和LEE组在皮质醇应激反应方面没有差异，但情绪化进食显着缓和了皮质醇应激反应与应激后与对照组食物摄入差异之间的关系。然而，HEE参与者的皮质醇应激反应迟钝，比那些皮质醇应激反应升高的人在痛苦后吃了更多的食物，LEE参与者没有表现出这种关系。这些发现支持了基于动物模型的相关性，该模型基于人类高情绪进食者的皮质醇应激反应迟钝与应激诱导的食物摄入增加之间的关系。
Animal studies suggest a relationship between blunted HPA-axis stress reactivity and increased stress-induced food intake in chronically stressed animals. Such a relationship can potentially explain the underlying mechanisms of emotional eating in humans. However, no studies have experimentally tested the relationship between stress-induced cortisol responses and acute food intake in high and low emotional eaters. We studied these effects in 46 female students that were preselected on the basis of extremely high (HEE) or low (LEE) scores on an emotional eating questionnaire. Using a within subject design we measured the difference of actual food intake after a control or a stress task (Trier Social Stress Test). The HEE and LEE groups did not differ in their cortisol stress reactivity but emotional eating significantly moderated the relationship between cortisol stress reactivity and the difference of food intake after stress vs control. Whereas HEE participants with a blunted cortisol stress response ate more food after distress than those with an elevated cortisol stress response, LEE participants showed no such relationship. These findings support the relevance of an animal based model on the relationship between a blunted cortisol stress response and increased stress-induced food intake for human high emotional eaters.
