目的：本研究探讨生理和主观唤醒对食物环境的影响，如进食地点、其他人的存在、声音和时间，以及对食物摄入量的影响。假设环境刺激对食物摄入的影响可能是由唤醒介导的。方法：要求大学生佩戴心率监测仪，并在7天饮食日记中记录他们的食物摄入量。每顿饭的主观唤醒（兴奋和兴奋）和饮食环境的各个方面都被记录下来。结果：主观唤醒似乎与食物摄入量有关（P < 0.01），似乎受到就餐地点（P < 0.01）和在场人数（P < 0.01）等环境刺激的影响，但部分环境刺激对心率的影响较小，餐馆平均心率较高（P < 0.05）。没有检测到心率对食物摄入量的影响。回归分析未能显示唤醒是环境刺激和食物摄入之间的重要中介。结论：可以得出结论，对于正常个体在日常环境中，环境对食物摄入的影响不是由唤醒的变化介导的。然而，环境和个人的情绪状态似乎在个人的饮食行为中起着作用。(C) 2006爱思唯尔公司版权所有。
Objectives: This study explored the influence of physiologic and subjective arousal on ambient factors of the food environment, such as the eating location, the presence of other people, sound, and time of day and on food intake. It was hypothesized that the influence of environmental stimuli on food intake would be mediated by arousal.Methods: College students were asked to wear heart rate monitors and to record their food intake in a 7-d diet diary. Subjective arousal (elation and excitement) and aspects of the eating environment were recorded for each meal occasion.Results: Results showed that subjective arousal seems to be related to food intake (P < 0.01) and appears to be affected by environmental stimuli such as the eating location (P < 0.01) and the number of people present (P < 0.01), but only small effects of some environmental stimuli on heart rate were found with higher average heart rates in restaurants (P < 0.05). No effects of heart rate on food intake were detected. Regression analyses failed to show arousal as a significant mediator between environmental stimuli and food intake.Conclusion: It can be concluded that, for normal individuals in their everyday environment, ambient influences on food intake are not mediated by changes in arousal. However, the environment and the emotional state of the individual appear to play a role in the individual's eating behavior. (C) 2006 Elsevier Inc. All rights reserved.
