肥胖是由于能量平衡长期失调造成的，这可能部分是由压力引起的。我们的目的是调查急性和心理应激对食物摄入的影响，使用在没有饥饿的情况下进食的范例，在正常和超重的男性和女性（同时考虑饮食限制和去抑制）。129例受试者（BMI = 24.5 +/- 3.4 kg/m2，年龄= 27.6 +/- 8.8岁），在三因素饮食问卷中确定得分（饮食限制= 7.2 +/- 4.4;解除抑制= 4.5 +/- 2.6;饥饿感= 3.9 +/- 2.6）和状态-特质焦虑量表（特质得分= 31.7 +/- 24.2）。在一个随机交叉设计中，“在没有饥饿的情况下进食”方案被测量为急性压力与对照任务和状态焦虑评分的函数。应激状态下大鼠从甜食中摄取的能量（708.1 kJ比599.4 kJ，P < 0.03）和总能量（965.2 kJ比793.8 kJ，P < 0.01）显著高于对照组。应激和对照条件下的能量摄入差异是应激任务期间状态焦虑评分（Delta状态焦虑评分）增加的函数（R-2 = 0.05，P < 0.01）。这种正相关性在去抑制评分高的受试者中更强（R-2 = 0.12，P < 0.05）。特质焦虑得分与状态焦虑得分呈显著正相关（R-2 = 0.07，P < 0.05）。我们的结论是，急性心理压力与在没有饥饿的情况下进食有关，特别是在易受伤害的个体中，其特征是不受抑制的进食行为和对慢性压力的敏感性。
Obesity results from chronic deregulation of energy balance, which may in part be caused by stress. Our objective was to investigate the effect of acute and psychological stress on food intake, using the eating in the absence of hunger paradigm, in normal and overweight men and women (while taking dietary restraint and disinhibition into account). In 129 subjects (BMI = 24.5 +/- 3.4 kg/m(2) and age = 27.6 +/- 8.8 years), scores were determined on the Three Factor Eating Questionnaire (dietary restraint = 7.2 +/- 4.4; disinhibition = 4.5 +/- 2.6; feeling of hunger = 3.9 +/- 2.6) and State-Trait Anxiety Inventory (trait score = 31.7 +/- 24.2). In a randomized crossover design, the "eating in absence of hunger" protocol was measured as a function of acute stress vs. a control task and of state anxiety scores. Energy intake from sweet foods (708.1 kJ vs. 599.4 kJ, P < 0.03) and total energy intake (965.2 kJ vs. 793.8 kJ, P < 0.01) were significantly higher in the stress condition compared to the control condition. Differences in energy intake between the stress and control condition were a function of increase in state anxiety scores during the stress task (Delta state anxiety scores) (R-2 = 0.05, P < 0.01). This positive relationship was stronger in subjects with high disinhibition scores (R-2 = 0.12, P < 0.05). Differences in state anxiety scores were a function of trait anxiety scores (R-2 = 0.07, P < 0.05). We conclude that acute psychological stress is associated with eating in the absence of hunger, especially in vulnerable individuals characterized by disinhibited eating behavior and sensitivity to chronic stress.
