纵向数据表明，我们的适应性自我调节能力是一种相对稳定的倾向，出现在童年时期，并预测未来生活的成功。 2004 年，我们发表了第一项研究，证明超重/肥胖成年女性存在决策缺陷。本研究是这些发现的延伸。我们对患有暴食症 (BED) 的肥胖女性 (n = 65) 和不患有暴食症 (BED) 的肥胖女性 (n = 73) 以及一组体重正常的女性 (n = 71) 进行了两项神经心理学测试：爱荷华州赌博任务和延迟折扣测量。与正常对照组相比，暴食症组和肥胖组在这两项任务上的表现得分较差，但彼此没有差异。这些发现表明，适应性决策和延迟满足的能力可能会影响我们的饮食行为，特别是在努力控制能量摄入对于维持健康体重至关重要的食品环境中。根据社会经济地位和体重之间已建立的联系，教育水平也存在群体差异，BED 较少且肥胖者拥有高等教育学位。有趣的是，当将教育水平添加到模型中时，受过高等教育的人在这两项任务上都表现更好，并且组间差异并不显着。 (C) 2009 Elsevier Ltd. 保留所有权利。
Longitudinal data indicate that Our capacity for adaptive self-regulation is a relatively stable predisposition that appears in childhood and predicts future life Successes. In 2004, we published the first study demonstrating decision-making deficits in overweight/obese adult women. The present Study is an extension of these findings. We assessed obese women with (n = 65) and without (n = 73) binge-eating disorder (BED), and a group (n = 71) of normal-weight women, on two neuropsychological tests: the Iowa Gambling Task and a Delay Discounting measure. The BED and obese groups had worse performance scores on both tasks compared to normal controls, but did not differ from each other. These findings suggest that adaptive decision-making and the ability to delay gratification may influence our eating behaviours, particularly in a food environment where effortful control of energy intake is essential for the maintenance of a healthy body weight. There were also group differences in education level with fewer BED and obese individuals having a post-secondary degree, in accord with established links between socioeconomic status and body weight. Interestingly, when education level was added to the models, those with a higher education performed better on both tasks, and the group differences were not significant. (C) 2009 Elsevier Ltd.
