Front-of-pack (FOP) nutrition labelling has been proposed as a tool for helping consumers make healthy choices. Before determining its effects on consumer behaviour, factors involved in its use must be elucidated, i.e. understanding and acceptability on the part of the consumer. Among five FOP labels, we sought to determine which formats were most easily understood and accepted by a large sample of adults.
Among 39 370 adults who participated in the French Nutrinet-Santé cohort study, understanding and indicators of acceptability (attitude, liking, visual attractiveness and perceived cognitive workload) were measured for five FOP labels: The currently used 'multiple traffic lights' (MTL) and 'simple traffic lights' (STL), and the 'colour range' logo (CR), the 'green tick' and the PNNS logo. We investigated the contribution of the different elements to consumer perception of FOP labels using multiple correspondence analyses.
Over half of the sample population showed a high level of understanding and perceived no discomfort in terms of the different logos. Label formats were positioned along an acceptability gradient ranging from acceptance to rejection, consisting of 'liking', 'attractiveness' and indicators of perceived cognitive workload. MTL was significantly more often liked and was viewed as reliable and informative. MTL, STL and the green tick performed better than the CR and PNNS logos in terms of ease of identification and comprehension. CR was clearly the least appreciated and it had the most complex format.
Consumers prefer FOP labels which give complete, reliable and simplified information on the nutrient quality of foods.
包装正面营养标签已被提议作为帮助消费者做出健康选择的工具。在确定其对消费者行为的影响之前,必须阐明其使用涉及的因素,即消费者的理解和可接受性。在五种包装正面标签中,我们试图确定哪种格式最容易被大量成年人理解和接受。
在参加法国 Nutrinet-Santé 队列研究的 39370 名成年人中,我们测量了五种包装正面标签的理解和可接受性指标(态度、喜好、视觉吸引力和感知认知工作量):目前使用的“多信号灯”(MTL)和“简单信号灯”(STL),“颜色范围”标志(CR)、“绿色勾号”和 PNNS 标志。我们使用多元对应分析研究了不同元素对消费者对包装正面标签的感知的贡献。
超过一半的样本人群对不同的标志表现出较高的理解水平,并且在感知方面没有不适感。标签格式沿着从接受到拒绝的可接受性梯度排列,包括“喜好”、“吸引力”和感知认知工作量指标。MTL 明显更受喜爱,被认为是可靠和信息丰富的。在识别和理解方面,MTL、STL 和绿色勾号的表现优于 CR 和 PNNS 标志。CR 明显是最不受欢迎的,它的格式也最复杂。
消费者更喜欢提供有关食品营养质量的完整、可靠和简化信息的包装正面标签。
