BACKGROUND
The aim of this study was to investigate whether a subject's level of satiety influences perception of their usual portion size.
METHODS
A total of 62 school children were recruited for the pilot study. Half of the group assessed food photographs for their usual portion size before lunch, and half after lunch. For the main study, 55 female students were recruited to test within-subject variation in perception of usual portion size before and after consuming a preload.
RESULTS
Significant differences in perception of portion size were found for four of the six foods used.
CONCLUSION
Some subjects' perception of their usual portion size was influenced by their level of satiety. Further study is needed to investigate this using a wider variety of food photographs and an alternative preload.
背景
本研究的目的是调查受试者的饱腹感水平是否会影响他们对平常食量的认知。
方法
共有62名学童被招募参与试点研究。该组中有一半人在午餐前评估食物照片以确定他们平常的食量，另一半人在午餐后进行评估。在主要研究中，招募了55名女学生，以测试在食用预负荷食物前后对平常食量认知的受试者内差异。
结果
在所使用的六种食物中，有四种食物的食量认知存在显著差异。
结论
一些受试者对他们平常食量的认知受到饱腹感水平的影响。需要进一步研究，使用更多种类的食物照片和替代预负荷来对此进行调查。
