营养成分标签可以让消费者更好地了解其饮食的营养成分，但是，消费者目前并不能很好地理解这些标签或经常使用它们。因此，修改现有标签可能有益于公众健康。本研究跟踪了做出模拟食品购买决策的个人的视觉注意力，以评估营养成分标签的观看情况。主要研究问题是自我报告的营养成分标签及其成分的查看如何与测量的查看相关，以及标签的位置和特定标签成分是否与查看相关。该研究涉及在配备眼球追踪摄像头的计算机上进行的模拟杂货购物练习。任务后调查评估了自我报告的营养信息查看、健康行为和人口统计数据。 18 岁及以上且能够在计算机上阅读英语单词的个人 (n=203) 于 2010 年春季在明尼苏达大学完成了 1 小时的实验方案。主要分析包括 χ2、方差分析以及比较自我报告和测量的不同呈现配置中标签组件查看情况的 t 检验。自我报告的营养成分标签成分查看率高于客观测量的查看率。标签顶部的标签组件比底部的标签组件被查看的次数更多，位于屏幕中央的标签比位于两侧的标签组件的查看次数更多。营养成分标签在查看区域内的位置以及标签上特定成分的位置与查看相关。眼动追踪是一项有价值的技术，可用于评估消费者对营养信息的关注度、告知营养标签政策（例如包装正面标签）以及设计最能支持健康饮食决策的标签。
Nutrition Facts labels can keep consumers better informed about their diets' nutritional composition, however, consumers currently do not understand these labels well or use them often. Thus, modifying existing labels may benefit public health. The present study tracked the visual attention of individuals making simulated food-purchasing decisions to assess Nutrition Facts label viewing. Primary research questions were how self-reported viewing of Nutrition Facts labels and their components relates to measured viewing and whether locations of labels and specific label components relate to viewing. The study involved a simulated grocery shopping exercise conducted on a computer equipped with an eye-tracking camera. A post-task survey assessed self-reported nutrition information viewing, health behaviors, and demographics. Individuals 18 years old and older and capable of reading English words on a computer (n=203) completed the 1-hour protocol at the University of Minnesota during Spring 2010. Primary analyses included χ2, analysis of variance, and t tests comparing self-reported and measured viewing of label components in different presentation configurations. Self-reported viewing of Nutrition Facts label components was higher than objectively measured viewing. Label components at the top of the label were viewed more than those at the bottom, and labels positioned in the center of the screen were viewed more than those located on the sides. Nutrition Facts label position within a viewing area and position of specific components on a label relate to viewing. Eye tracking is a valuable technology for evaluating consumers' attention to nutrition information, informing nutrition labeling policy (eg, front-of-pack labels), and designing labels that best support healthy dietary decisions.
