RESUMO
Objective: To examine sociodemographic differences in the awareness, understanding, use and effect of nutrition labels among Mexican and Chilean youth. Methods: Online surveys among youth (10-17 years) were obtained in 2019 (n=2631). Participants reported their awareness, understanding, and use of their country-specific nutrition facts tables (NFT) and front-of-pack labels (FOPL) (Chile: warning labels [WLs]; Mexico: guideline daily amounts [GDA]). Additionally, participants reported their perceived healthfulness of a sweetened fruit drink after viewing one of six versions of it with different FOPL (no-label control, Health Star Rating, WLs, GDAs, Traffic Light, or Nutri-Score) during an experimental task. Results: Higher self-reported nutrition knowledge was associated with higher NFT and FOPL awareness, understanding, and use, except for WL use. WLs were the most effective FOPL in decreasing the perceived healthfulness of the sweetened fruit drink compared to a no-label condition and other FOP labels. In Chile, the effect of GDA differed by income adequacy, while in Mexico Nutri-Score differed by age. Conclusions: Results suggest that nutrition label awareness, use, understanding, and impact differ across demographics, favoring higher income and nutrition knowledge. Despite this, WLs are likely to have a positive impact on nutrition-related knowledge and behaviors among Mexican and Chilean youth, independently of their socio-demographic groups.
RESUMO
Deaths attributable to unhealthful eating underscore the need to improve dietary patterns through upstream, policy-led solutions. The approval and successful implementation of food policies is partly determined by their public acceptance. Little is known about public support for food policies in Mexico. We aimed to investigate the level of public support for 30 food policies, grouped into 5 domains, and their associated characteristics among Mexican adults. Data are from the 2017-2021 International Food Policy Study (IFPS), a cross-sectional web-based survey of adults. Differences in public support across years were estimated using linear regression models. The association between demographic characteristics and policy support was analyzed using multivariate logistic regression models. The highest mean support was for the subsidies and benefits domain, followed by the labelling and reformulation domain. The level of support varied across years and policy domains. Support was higher in 2019 compared to 2017 and 2018, and subsequently lower in 2020 and 2021 compared to previous years. Older age was associated with greater support across all domains (OR ranged from 0.002 to 0.004, p < 0.01). Female participants and those selfidentifying as indigenous showed greater support for certain policy domains, whereas higher income adequacy was associated with lower support for other policy domains. In Mexico, support for food policies varies across subpopulations. Our findings may serve as a guide to the development and promotion of food policies in Mexico, as well as to improve their feasibility and success.
RESUMO
OBJECTIVE: Front-of-package warning labels introduced in Mexico in 2020 included disclaimers that caution against allowing children to consume products with non-sugary sweeteners and caffeine. We examined the awareness and use of the disclaimers among Mexican adults and youth 1 month after the regulation was implemented. We also investigated their impact on the perceived healthfulness of industrialised beverages designed for children. DESIGN: Data on the awareness and use of the disclaimers were analysed. Two between-subjects experiments examined the effect of a sweetener disclaimer (Experiment 1, youth and adults) or a caffeine disclaimer (Experiment 2, only adults) on the perceived healthfulness of industrialised beverages. Interactions between experimental conditions and demographic characteristics were tested. SETTING: Online survey in 2020. PARTICIPANTS: Mexican adults (≥18 years, n 2108) and youth (10-17 years, n 1790). RESULTS: Most participants (>80 %) had seen the disclaimers at least rarely, and over 60 % used them sometimes or frequently. The sweetener disclaimer led to a lower perceived healthfulness of a fruit drink (adults: 2·74 ± 1·44; youth: 2·04 ± 0·96) compared with the no-disclaimer condition (adults: 3·17 ± 1·54; youth: 2·32 ± 0·96) (t's: >4·0, P values: <0·001). This effect was larger among older adults and male youth. The caffeine disclaimer did not affect adult's perceived healthfulness of a caffeinated drink (t = 0·861, P value = 0·3894). CONCLUSIONS: There were high awareness and use of the sweeteners and caffeine disclaimers shortly after the warning labels were implemented. The sweetener disclaimer appears to be helping consumers modify their perceptions regarding industrialised beverages for children. Findings may help decision-makers improve the regulation and better target communication strategies.

RESUMEN Objetivo. Examinar las diferencias sociodemográficas por lo que respecta al conocimiento, la comprensión, el uso y el efecto de las etiquetas nutricionales en adolescentes de México y Chile. Métodos. En el 2019 se efectuó una encuesta en línea en adolescentes (10 a 17 años) (n=2631). Los participantes indicaron su conocimiento, comprensión y uso de los cuadros de información nutricional y los etiquetados frontales específicos de los empaques de su país (en el caso de Chile, las etiquetas de advertencia, y en el de México, las guías diarias de alimentación (GDA). Asimismo, se llevó a cabo un experimento en el que los participantes indicaron su percepción de lo saludable que era una bebida de fruta azucarada después de ver una de sus seis versiones con diferentes etiquetas frontales en los envases (control sin etiqueta, calificación de producto saludable mediante estrellas Health Star, etiquetas de advertencia, GDA, colores del semáforo, o sistema Nutri-Score). Resultados. El autorreporte de un mayor conocimiento sobre nutrición por parte de los participantes se asoció a un mayor conocimiento, comprensión y uso de los cuadros de información nutricional y los sistemas de etiquetado frontal, excepto en el caso del uso de las etiquetas de advertencia. Las etiquetas de advertencia fueron el sistema de etiquetado frontal más eficaz para reducir la percepción saludable del producto con respecto a la bebida de fruta azucarada, en comparación con la ausencia de etiqueta y el resto de los etiquetados frontales. En Chile, el efecto de las GDA variaba en función de la adecuación del ingreso, mientras que en México el efecto del Nutri-Score difería según la edad. Conclusiones. Los resultados sugieren que el conocimiento, el uso, la comprensión y el efecto de las etiquetas nutricionales difieren entre los distintos grupos demográficos, de tal manera que son más favorables en las personas con mayores ingresos y conocimientos de nutrición. A pesar de esto, es probable que las etiquetas de advertencia tengan un impacto positivo sobre los conocimientos y los comportamientos relacionados con la nutrición en los adolescentes de México y Chile, con independencia de los grupos sociodemográficos de los que forman parte.
RESUMO Objetivo. Analisar diferenças sociodemográficas em termos de conhecimento, compreensão, uso e efeito da rotulagem nutricional entre adolescentes mexicanos e chilenos. Métodos. Foram realizadas pesquisas on-line entre adolescentes de 10 a 17 anos ao longo de 2019 (n=2631). Os participantes relataram que conheciam, compreendiam e usavam as tabelas de informação nutricional e a rotulagem frontal de embalagens específicas de seus respectivos países (Chile: rotulagem de advertência; México: valores diários de referência). Além disso, os participantes relataram sua percepção sobre a saudabilidade de um suco de fruta adoçado depois de ver uma de seis versões diferentes de rotulagem frontal (controle sem rótulo, Health Star Rating, rótulos de advertência, valores diários de referência, semáforo nutricional ou Nutri-Score) durante uma tarefa experimental. Resultados. Um maior conhecimento autodeclarado sobre nutrição foi associado a maior conhecimento, compreensão e uso de tabelas de informação nutricional e rotulagem frontal, com exceção do uso de rótulos de advertência. Os rótulos de advertência foram o tipo de rotulagem frontal mais efetivo para reduzir a percepção de saudabilidade do suco de fruta adoçado em comparação com o controle sem rótulo e outros tipos de rotulagem frontal. No Chile, o efeito dos valores diários de referência variou de acordo com a renda, enquanto no México o Nutri-Score variou de acordo com a idade. Conclusões. Os resultados sugerem que o conhecimento, a compreensão, o uso e o impacto da rotulagem nutricional variam de acordo com fatores demográficos, favorecendo uma renda mais alta e conhecimento sobre nutrição. Apesar disso, é provável que os rótulos de advertência tenham um impacto positivo sobre o conhecimento e os comportamentos relativos à nutrição entre adolescentes mexicanos e chilenos, independentemente do grupo sociodemográfico a que pertencem.
