“…17 This is similar to the final format of the labels implemented in Chile, with a slight difference in wording, which ended up with the text "High in…" for the warning labels. So far, study methods have focused on either virtual stores or shopping simulations, and no studies have investigated in-store sales.…”

Objective: The Health Star Rating (HSR) is a voluntary front-of-pack nutrition labelling system that rates products from ½ to 5 stars (five being healthiest). The Chilean Warning Label system displays warnings on foods high in sugar, saturated fat, sodium, or energy. We aimed to evaluate alignment between the systems.Methods: New Zealand packaged products (n=13,868) were classified according to the two systems. Alignment was assessed by cross-checking the number of products meeting the criteria for warnings against star ratings. Products with no warnings but an HSR <2, or with >1 warning but an HSR of ≥3.5 were considered outliers.Results: Two-thirds of products met the criteria for at least one warning. There was a significant positive relationship between the number of warnings and mean HSR: 0 warnings = HSR 3.77±.0166 (p<0.001), 1 warning = HSR 2.70±.0206 (p<0.001) and >1 warning = HSR 2.00±.0160 (p<0.001). The systems were non-aligned for 1,117 products (8%).Conclusion: HSR and the Chilean Warning Label systems are broadly aligned. Non-alignment is due to the Chilean system restricting warnings to foods containing added ingredients and HSR awarding points for positive components.Implications for public health: These results could be helpful in informing improvements to the HSR system.

“…An increasingly large number of studies evaluating FOP nutrition labels' impact on awareness [13,14], acceptability [15], understanding [14,16,17], use [13], or effects in healthfulness perceptions [18,19], have been conducted among Latin American populations. However, limited literature exists evaluating FOP label effects on consumer purchasing intentions (e.g.…”

Impact of front-of-pack nutrition labels on consumer purchasing intentions: a randomized experiment in low- and middle-income Mexican adults

Background: Front-of-pack (FOP) nutrition labeling is a cost-effective strategy to help consumers make informed and healthier food choices. We aimed to investigate the effect of the FOP labels used in the Latin American region on consumers' shopping intentions when prompted to make their choices with specific nutrients-to-limit in mind among low-and middle-income Mexican adults (> 18 y). Methods: In this experimental study of an online simulated shopping situation participants (n = 2194) were randomly assigned to one of three labeling conditions: Guideline Daily Amounts (GDA), Multiple Traffic Lights (MTL), or red Warning Labels (WL). Participants were required to view a video explaining how to correctly interpret the assigned label. Primary outcomes were the overall nutritional quality (estimated using the Nutrient Profiling Scoring Criterion [NPSC] and NPSC baseline score) and mean energy and nutrient content of purchases. Secondary outcomes included shopping time variables. We also evaluated the impact of the labels across food categories (ready-made foods, dairy beverages, non-dairy beverages, salty snacks, and breakfast cereals) and sociodemographic subgroups.Results: The MTL and the WL led to a better overall nutritional quality of the shopping cart compared to the GDA (p < 0.05). According to the NPSC score, the WL led to a better nutritional quality across breakfast cereals and salty snacks compared to the GDA (p < 0.05); a similar effect was observed for the MTL among non-dairy beverages (p < 0.05). The MTL and the WL required shorter shopping times compared to GDA (p < 0.05). Across all labeling conditions, the nutritional quality of the shopping cart tended to be lower among those with low income, education and nutrition knowledge levels.Conclusion: WL and MTL may foster healthier food choices in a faster way among low-and middle-income groups in Mexico. To produce an equitable impact among consumers of all socioeconomic strata, efforts beyond simply the inclusion of a communication campaign on how to use and interpret FOP labels will be required.(Continued on next page)

“…Esto sugiere que este tipo de EFP se entiende mejor una vez que se identifica y que, incluso, podría ser más efectivo si se presentara en colores más destacados. 29 En la vida real, más allá de la codificación por colores, un aspecto clave del mejor rendimiento del Nutri-Score observado en muchos estudios 9 puede estar relacionado con el uso de un indicador único que resume la calidad nutricional del alimento, en lugar de múltiples evaluaciones relacionadas con nutrientes. Los estudios anteriores han demostrado que los indicadores de resumen son más fáciles de entender por los consumidores, 19,20,30 en particular en las poblaciones vulnerables, las cuales son un objetivo importante en las políticas de nutrición de salud pública.…”

Objetivo. Evaluar la comprensión objetiva de cinco tipos de etiquetados frontales de paquetes (EFP) (Sistema de Clasificación de Estrellas de Salud, Semáforo Múltiple, Nutri-Score, Ingestas de Referencia y Símbolo de Advertencia) en México. Material y métodos. Se reclutaron 1 001 consumidores mexicanos para clasificar tres productos de tres categorías de alimentos sin EFP, según su calidad nutricional. Se les asignó al azar uno de los cinco EFP para clasificar los mismos productos, esta vez con un EFP en el empaque. El cambio en la capacidad para clasificar correctamente los productos en las dos tareas fue evaluado por EFP, utilizando un modelo de regresión logística ordinal. Resultados. Nutri-Score y Semáforo Múltiple obtuvieron un mejor desempeño, seguidos del Símbolo de Advertencia, Sistema de Clasificación de Estrellas de Salud e Ingestas de Referencia. Conclusión. Nutri-Score y el Semáforo Múltiple surgen como esquemas eficientes para informar a los consumidores sobre la calidad nutricional de los alimentos en México, donde podrían ser una herramienta útil para los consumidores en situación de compra.
