背景瑞士与其他高收入国家一样，正面临着重大的公共卫生挑战，非传染性疾病的负担日益加重。目前，瑞士正在讨论实施包装正面营养标签（FoPL）作为一项公共卫生措施，以引导消费者选择更健康的食品，营养评分是一种得到多方支持的替代方案。到目前为止，还没有研究调查瑞士消费者中营养评分的表现。这项研究旨在比较瑞士消费者对五种FoPL的反应（健康星星评级系统，多个交通灯，营养分数，参考摄入量和警告符号）在感知和理解这些标签和对食物选择的影响方面。研究人员招募了088名瑞士消费者，要求他们从三种营养成分不同的食品中选择一种，然后将根据产品的营养质量，在没有标签的情况下执行任务，然后使用五个FoPL中的一个-取决于他们被随机分配的组-在包装上。最后，参与者被问及他们的看法，他们所暴露的标签。ResultsAll FoPLs有利地认为，FoPLs之间的边际差异。Nutri-Score在帮助消费者根据其营养质量对产品进行排名方面表现出最高的改善百分比和最高的整体性能。ConclusionOverall，Nutri-Score是告知瑞士消费者食品营养质量的最有效的FoPL，因此可以成为改善食品选择和减轻瑞士慢性疾病负担的有用工具。
BackgroundSwitzerland, like other high-income countries, is facing a major public health challenge with the increasing burden of non-communicable diseases. Discussions are currently on-going in Switzerland regarding the implementation of a Front-of-Pack nutrition label (FoPL) as a public health measure to guide consumers towards healthier food choices, and the Nutri-Score represents an alternative supported by multiple actors. To date, no studies have investigated the performance of the Nutri-Score among Swiss consumers. This study aimed to compare the response of Swiss consumers to five FoPLs (Health Star Rating system, Multiple Traffic Lights, Nutri-Score, Reference Intakes and Warning symbol) in terms of perception and understanding of these labels and effects on food choices.MethodsIn 2019, 1,088 Swiss consumers were recruited and asked to select one product from among a set of three foods with different nutritional profiles and then classify the products within the sets according to their nutritional quality. Tasks were performed in situations without a label and then with one of the five FoPLs-depending on the group in which they were randomized-on the pack. Finally, participants were questioned on their perceptions regarding the label to which they were exposed.ResultsAll FoPLs were favorably perceived, with marginal differences between FoPLs. The Nutri-Score demonstrated the highest percentage of improvement in food choices and the highest overall performance in helping consumers rank the products according to their nutritional quality.ConclusionOverall, the Nutri-Score was the most efficient FoPL in informing Swiss consumers of the nutritional quality of food products, and as such could be a useful tool to improve food choices and reduce the burden of chronic diseases in Switzerland.
