越来越多的证据表明，饮食失调与面部表情识别和情绪处理问题有关。在这项研究中，我们调查的问题是否厌食症和肥胖症发生在一个连续的注意力偏向负面的面部表情相比，健康的个人正常体重。33例限制性神经性厌食症（AN-R）患者，30例肥胖症（OB）患者和63名健康年龄和社会经济状况匹配的对照组被招募。我们的研究结果表明，AN-R患者更关注愤怒的面孔，并在关注积极的表情有困难，而OB患者有问题，在寻找或关注独立于自我报告的抑郁和焦虑的负面表达。我们的研究结果并不支持AN-R和OB发生在连续体上的观点。我们发现AN-R与积极面部表情处理能力的降低有关，而OB与消极面部表情处理能力的降低有关。我们的研究结果的社会相关性和可能的解释基于神经科学进行了讨论。(C)2010爱思唯尔爱尔兰有限公司版权所有。
There is growing evidence that disordered eating is associated with facial expression recognition and emotion processing problems. In this study, we investigated the question of whether anorexia and obesity occur on a continuum of attention bias towards negative facial expressions in comparison with healthy individuals of normal weight. Thirty-three patients with restrictive anorexia nervosa (AN-R), 30 patients with obesity (OB) and 63 healthy age and social-economic status matched controls were recruited. Our results indicated that AN-R patients were more attentive to angry faces and had difficulties in being attentive to positive expressions, whilst OB patients had problems in looking for or being attentive to negative expressions independently of self-reported depression and anxiety. Our findings did not support the idea that AN-R and OB occur on a continuum. We found that AN-R was associated with a reduced capacity in positive facial expression processing, whereas OB was associated with a reduced capacity in negative facial expressions processing. The social relevance of our findings and a possible explanation based upon neuroscience are discussed. (C) 2010 Elsevier Ireland Ltd. All rights reserved.
