OBJECTIVE
To compare the microstructural eating behavior of obese patients with and without binge eating disorder (BED) after stress induction in laboratory.
METHOD
Forty-eight obese women were investigated. Seventeen were assigned to the group of BED. Group (BED vs. non-BED) by condition (stress vs. no stress) interaction effect on feeding variables, measured by a universal eating monitor, was tested. Stress was induced by the trier social stress test (TSST) and chocolate pudding served as laboratory food.
RESULTS
From the nonstress to the stress condition, patients with BED, when compared with non-BED had a greater increase in average eating rate (p < .01) and a corresponding greater increase in the frequency of spoonfuls (p < .02). The BED group also showed a different change in acceleration/deceleration from the nonstress to the stress condition compared to the non-BED group (p < .04).
DISCUSSION
Obese individuals with BED appear to exhibit a different response to stress than obese non-BED individuals and individuals with bulimia nervosa.
目的
比较有和没有暴饮暴食症（BED）的肥胖患者在实验室应激诱导后的微观结构饮食行为。
方法
对48名肥胖女性进行了调查。17人被分配到暴饮暴食症组。通过通用饮食监测仪测量，测试了条件（应激与非应激）交互作用对两组（暴饮暴食症组与非暴饮暴食症组）进食变量的影响。采用特里尔社会应激测试（TSST）诱导应激，巧克力布丁作为实验室食物。
结果
从非应激状态到应激状态，与非暴饮暴食症组相比，暴饮暴食症患者的平均进食速度增加幅度更大（p < 0.01），相应地，每勺进食频率的增加幅度也更大（p < 0.02）。与非暴饮暴食症组相比，暴饮暴食症组从非应激状态到应激状态的加速/减速变化也有所不同（p < 0.04）。
讨论
患有暴饮暴食症的肥胖个体与非暴饮暴食症的肥胖个体以及神经性贪食症个体相比，似乎对应激表现出不同的反应。
