Body dissatisfaction is a key predictor of binge eating, yet less is known about factors that may potentiate the association between body dissatisfaction and binge eating. This study examined self-reported dietary restraint and sweet taste reward sensitivity as candidate moderators of the association between body dissatisfaction and binge eating in adults. A convenience sample of 221 tobacco product users completed measures of eating disorder pathology and sweet taste reward sensitivity. Results revealed that elevated sweet taste reward sensitivity strengthened the positive association between higher body dissatisfaction and binge eating. However, there was no main effect, or moderation effect, of dietary restraint on binge eating. The findings of this study demonstrate the key role of sweet taste reward sensitivity in potentiating the association between body dissatisfaction and binge eating. Sweet taste reward sensitivity may serve as a key dispositional factor for uncontrolled eating.
身体不满是暴食的一个关键预测因子，但对于可能增强身体不满和暴食之间关联的因素知之甚少。本研究探讨了自我报告的饮食抑制和甜味奖励敏感性作为身体不满和暴食之间关联的候选调节因素。一个方便的 221 名烟草产品使用者样本完成了饮食失调病理和甜味奖励敏感性的测量。结果表明，甜味奖励敏感性的提高增强了身体不满与暴食之间的正相关关系。然而，饮食抑制对暴食没有主要作用或调节作用。本研究的结果表明，甜味奖励敏感性在增强身体不满和暴食之间的关联方面起着关键作用。甜味奖励敏感性可能是暴饮暴食的关键特质因素。
