Non-human animal studies demonstrate relationships between stress and selective intake of palatable food. In humans, exposure to laboratory stressors and self-reported stress are associated with greater food intake. Large studies have yet to examine chronic stress exposure and eating behavior. The current study assessed the relationship between stress (perceived and chronic), drive to eat, and reported food frequency intake (nutritious food vs. palatable non-nutritious food) in women ranging from normal weight to obese (N=457). Greater reported stress, both exposure and perception, was associated with indices of greater drive to eat-including feelings of disinhibited eating, binge eating, hunger, and more ineffective attempts to control eating (rigid restraint; r's from .11 to .36, p's<.05). These data suggest that stress exposure may lead to a stronger drive to eat and may be one factor promoting excessive weight gain. Relationships between stress and eating behavior are of importance to public health given the concurrent increase in reported stress and obesity rates.
非人类动物研究表明，压力与美味食物的选择性摄入之间存在关系。在人类中，暴露于实验室应激源和自我报告的压力与更大的食物摄入量有关。大型研究尚未研究慢性应激暴露与饮食行为之间的关系。本研究评估了压力（感知和慢性）、进食驱动力以及报告的食物频率摄入（营养食物与美味非营养食物）之间的关系，研究对象为体重正常到肥胖的女性（N=457）。更多的报告压力，无论是暴露还是感知，与更大的进食驱动力指标相关，包括抑制性进食、暴食、饥饿和更无效的控制进食的尝试（刻板约束；r 值从.11 到.36，p 值<.05）。这些数据表明，压力暴露可能导致更强的进食驱动力，可能是促进体重过度增加的一个因素。鉴于报告的压力和肥胖率同时增加，压力与饮食行为之间的关系对公共卫生很重要。
