Compare consumers' overall label comprehension of the original Nutrition Facts (NF) label with the updated label.
Online survey conducted in 2019. Participants randomly assigned to original label, updated-single column, or updated-dual column labeling condition and asked to complete a series of label comprehension questions.
Online survey; participants recruited through Prolific.
N = 992 U.S. adults. Sample similar to U.S. population in terms of sex (49.2% female), race (73.3% White/Caucasian), and household size (mean = 2.7 members). However, sample was younger (median age: 29.0), more educated (98.8% high school graduate or higher), and exhibited a lower rate of obesity (22.6% obese) than the U.S. population.
Dependent variables: objective (% correct) NF label comprehension. Independent variables: label condition, nutrition knowledge, and socio-demographic variables.
Regression analysis assessed relationships between label condition and label comprehension. Significance level of 5% used for analyses.
Average score for objective comprehension was 81.4%. The updates did not significantly improve label comprehension. Participants in the updated NF label conditions had trouble answering questions related to total and added sugars.
Results suggest consumers may struggle to correctly utilize information on the updated NF label, specifically total and added sugars. Consumers may benefit from educational opportunities on using the new label.
比较消费者对原始营养成分表(NF)标签与更新标签的整体标签理解。
2019 年进行的在线调查。参与者被随机分配到原始标签、更新单栏或更新双栏标签条件,并被要求完成一系列标签理解问题。
在线调查;通过 Prolific 招募参与者。
992 名美国成年人。从性别(49.2%为女性)、种族(73.3%为白种人/高加索人)和家庭规模(平均为 2.7 人)方面来看,样本与美国人口相似。然而,与美国人口相比,该样本更年轻(中位数年龄:29.0 岁)、受教育程度更高(98.8%为高中或以上学历),肥胖率更低(22.6%为肥胖)。
因变量:客观(正确百分比)NF 标签理解。自变量:标签条件、营养知识和社会人口统计学变量。
回归分析评估了标签条件与标签理解之间的关系。分析采用 5%的显著性水平。
客观理解的平均得分为 81.4%。更新并没有显著提高标签理解。更新 NF 标签条件下的参与者在回答有关总糖和添加糖的问题时遇到了困难。
结果表明,消费者可能难以正确利用更新后的 NF 标签上的信息,特别是总糖和添加糖。消费者可能受益于使用新标签的教育机会。
