包装正面食品标签(FOPL)可以帮助消费者做出健康和知情的食品选择。FOPL用于食品市场，但对其理解和可接受性的评估很少。本研究旨在探讨西班牙裔消费者对四种FOPL的主观理解与接受程度。在墨西哥六个州的18所城市小学进行了一项定性研究。本研究选取135名五年级儿童家长为研究对象。评估了四个FOPL：标志、评级星级、指导每日津贴(GDA)和多个红绿灯(MTL)。训练有素的面试者使用面谈指南与参与者进行了18次焦点小组讨论。参与者被问及他们对FOPL的主观理解和接受程度，展示了为这项研究设计的16个通用早餐谷类食品盒(每个FOPL四个)，其营养价值各不相同。随后，参与者被要求从四个谷物盒中选择一个，以最好地传达产品的健康状况和他们选择的理由，改进FOPL的建议，以及新FOPL的理想特性。最后，应用了社会人口学调查问卷。使用Altlas.tiV5软件对焦点小组的转录进行主题分析。徽标被认为是易于理解、高度可接受和有助于决策的；机构对徽标的认可与对标签的更大信心有关。考虑到营养知识和解释所需的时间，GDA很难理解。评级明星与企业的质量有关，而不是与食品有关。MTL被认为表明了特定营养物质的高/低含量，但琥珀色的含义并未完全理解。与会者强调，需要一种简单的FOPL，使其能够在考虑食品购买时间限制和对食品部分的解释的同时，轻松识别健康产品。有机构认可的标识是最容易理解和接受的FOPL，而GDA和评级明星最不被理解和接受。我们的发现为了解拉美裔消费者对FOPL的看法提供了有价值的见解，并指导公共卫生政策。需要对患有慢性病和不同社会背景的人群进行进一步研究。
Front-of-pack food labels (FOPL) can help consumers make healthy and informed food choices. FOPL are used in the food market but evaluations of their understanding and acceptability are scanty. This study aimed to explore the subjective understanding and acceptability of four FOPL among Hispanic consumers. A qualitative study was conducted in six States of Mexico, in 18 urban elementary schools. A purposive sample of 135 parents of fifth-grade children was selected. Four FOPL were assessed: Logos, Rating Stars, Guideline Daily Allowances (GDA’s), and Multiple Traffic Lights (MTL). Trained interviewers performed 18 focus groups with the participants, using an interview guide. Participants were asked about their subjective understanding and acceptability of the FOPL, displaying 16 generic breakfast cereal boxes designed for this study (four for each FOPL), varying in their nutritional value. Afterwards, participants were asked to choose among the four cereal boxes the one to best communicate the product healthiness and their reasons for choice, proposals for improving the FOPL, and desirable characteristics for new FOPL. Finally, a socio-demographic questionnaire was applied. Thematic analysis of the transcriptions of the focus groups was performed, using Altlas.tiV5 software. Logos were perceived as easy to understand, highly acceptable, and useful for decision-making; institutional endorsement of Logos was related to greater confidence in the label. The GDA’s were hard to understand considering the nutritional knowledge and time needed for interpretation. The Rating Stars were related to the quality in businesses rather than foods. The MTL were viewed as indicating the high/low content of specific nutrients, but the meaning of the amber color was not fully understood. Participants highlighted the need for a simple FOPL that allows easily identification of healthy products while considering food purchasing time limitations and interpretation of food portions. Logos with an institutional endorsement was the best understood and accepted FOPL, and the GDA’s and Rating Stars were the least. Our findings provide valuable insights about Hispanic consumers´ perceptions regarding FOPL and to guide public health policy. Further studies are needed in populations with chronic diseases and diverse social contexts.
