这项研究的目的是扩展现有的研究渴望在暴食障碍(Bed)中的作用的工作。目前的研究使用病例对照设计，在被诊断为床上的人中，建立渴望和食物暴露之间的关系，以及渴望和食物消费之间的关系。29名有床的女性、40名肥胖对照组和50名正常体重的对照组首先被呈现一条中性线索，并完成了对食物的渴望测量。然后向他们展示他们最喜欢的零食，并再次完成渴望测试，之后他们被允许食用这些食物。与对照组相比，卧床组在渴求前后的评分明显更高，并摄入了更多的食物。然而，在群体和渴望得分之间没有显著的交互作用。结果还显示，在食物暴露前后，有床的个体的食物消费与饥饿感得分呈正相关。研究结果表明，暴露于食物之前的渴望程度可能足以预测在床上暴饮暴食，治疗可能希望将这一点作为区分有床的人和不暴饮暴食的人的一个定义特征。皇冠版权所有(C)2013由爱思唯尔有限公司出版。保留所有权利。
The purpose of this study was to extend existing work that examines the role of cravings in Binge Eating Disorder (BED). The current study uses a case-control design to establish a relationship between cravings and food exposure, and between cravings and food consumption in individuals diagnosed with BED. Twenty-nine females with BED, 40 obese controls, and 50 normal-weight controls were first presented with a neutral cue and completed a food-craving measure. They were then presented with their favourite snack food and completed the craving measure again, after which they were allowed to consume the food. The BED group had significantly higher scores for pre- and post-craving measures, and consumed more food compared to the controls. There was, however, no significant interaction between group and craving scores. Results also showed a positive correlation between food consumption and cravings scores both before and after food exposure for individuals with BED. The findings suggest that the level of cravings prior to food exposure may be sufficient to predict overeating in BED and that treatment may want to target this as a defining feature that differentiates individuals with BED from those who do not binge eat.
