The purpose of the study was to measure test meal consumption and the changes in hunger and fullness during a test meal in obese individuals with and without binge eating disorder (BED) and normal-weight controls.
Twelve women with BED, 12 obese control participants, and 12 normal-weight control participants participated in two single-item test meal sessions. In one session participants were instructed to "binge," and the other eat a normal meal. Participants made ratings of hunger and fullness on visual analog scales after every 75-g increment of food.
In comparison to obese or normal-weight controls, patients with BED consumed significantly more food to reach a similar level of fullness or hunger.
Individuals with BED consumed significantly more food and showed blunted changes in hunger and fullness during both the binge and nonbinge meals. These findings suggest that individuals with BED may have disturbances in satiety that in some ways resemble those described among individuals with bulimia nervosa.
本研究旨在测量患有和未患有暴饮暴食症(BED)的肥胖个体以及正常体重对照者在试餐期间的试餐摄入量以及饥饿感和饱腹感的变化。
12名患有BED的女性、12名肥胖对照参与者和12名正常体重对照参与者参加了两个单项试餐环节。在一个环节中,参与者被指示“暴饮暴食”,另一个环节则正常进食。参与者在每次食物增加75克后,用视觉模拟量表对饥饿感和饱腹感进行评分。
与肥胖或正常体重对照者相比,患有BED的患者为达到相似的饱腹感或饥饿感水平会摄入显著更多的食物。
患有BED的个体在暴饮暴食餐和非暴饮暴食餐期间摄入的食物显著更多,并且饥饿感和饱腹感的变化不明显。这些发现表明,患有BED的个体可能在饱腹感方面存在紊乱,在某些方面类似于神经性贪食症患者所描述的情况。
