Earlier research has identified consumer characteristics associated with viewing Nutrition Facts labels; however, little is known about those who view front-of-package nutrition labels. Front-of-package nutrition labels might appeal to more consumers than do Nutrition Facts labels, but it might be necessary to provide consumers with information about how to locate and use these labels.
This study quantifies Nutrition Facts and front-of-package nutrition label viewing among American adult consumers.
Attention to nutrition information was measured during a food-selection task.
PARTICIPANTS/SETTING: One hundred and twenty-three parents (mean age=38 years, mean body mass index [calculated as kg/m(2)]=28) and one of their children (aged 6 to 9 years) selected six foods from a university laboratory-turned-grocery aisle.
Participants were randomized to conditions in which front-of-package nutrition labels were present or absent, and signage explaining front-of-package nutrition labels was present or absent.
Adults' visual attention to Nutrition Facts labels and front-of-package nutrition labels was objectively measured via eye-tracking glasses.
To examine whether there were significant differences in the percentages of participants who viewed Nutrition Facts labels vs front-of-package nutrition labels, McNemar's tests were conducted across all participants, as well as within various sociodemographic categories. To determine whether hypothesized factors, such as health literacy and education, had stronger relationships with front-of-package nutrition label vs Nutrition Facts label viewing, linear regression assessed the magnitude of relationships between theoretically and empirically derived factors and each type of label viewing.
Overall, front-of-package nutrition labels were more likely to be viewed than Nutrition Facts labels; however, for all subgroups, higher rates of front-of-package nutrition label viewership occurred only when signage was present drawing attention to the presence and meaning of front-of-package nutrition labels.
Consumers should receive education about the availability and use of new nutrition labels.
早期研究已确定了与查看营养成分标签相关的消费者特征;然而,对于那些查看包装正面营养标签的人群了解甚少。包装正面营养标签可能比营养成分标签吸引更多消费者,但或许有必要向消费者提供有关如何查找和使用这些标签的信息。
本研究对美国成年消费者查看营养成分标签和包装正面营养标签的情况进行量化。
在一项食物选择任务中对营养信息关注度进行测量。
参与者/研究环境:123名家长(平均年龄 = 38岁,平均体重指数[以千克/平方米计算]=28)及其一名子女(6至9岁)从一个改造成食品杂货店过道的大学实验室中挑选六种食物。
参与者被随机分配到有或无包装正面营养标签以及有或无解释包装正面营养标签的标识牌的不同条件下。
通过眼动追踪眼镜客观测量成年人对营养成分标签和包装正面营养标签的视觉关注度。
为检验查看营养成分标签与包装正面营养标签的参与者百分比是否存在显著差异,对所有参与者以及不同社会人口学类别内的参与者进行了 McNemar 检验。为确定健康素养和教育等假设因素与包装正面营养标签查看和营养成分标签查看之间的关系是否更强,线性回归评估了理论和实证得出的因素与每种标签查看之间关系的强度。
总体而言,包装正面营养标签比营养成分标签更有可能被查看;然而,对于所有亚组,只有当有标识牌提请注意包装正面营养标签的存在及其含义时,包装正面营养标签的查看率才会更高。
应向消费者提供有关新营养标签的获取和使用的教育。
