Calidad de productos alimentarios anunciados por televisión antes y después del plan para mejorar su composición, 2017-2020 / Quality of food products announced on television before and after the plan to improve their composition, 2017–2020

Objetivo: Comparar la calidad nutricional de los alimentos y bebidas anunciados por televisión en España antes y después del plan para mejorar su composición. Método: Se grabaron las emisiones por televisión digital terrestre (TDT) en horario infantil de los canales más populares. Se registraron los productos anunciados en los cortes comerciales y su composición nutricional. Se comparó su distribución de frecuencias por categorías alimentarias y su adherencia al perfil nutricional de la Organización Mundial de la Salud en 2017 y 2020. Resultados: En 256 horas de emisión se identificaron 173 productos (78 en 2017 y 95 en 2020). Los más anunciados fueron los chocolates (26,9% en 2017 y 22,1% en 2020). El 76,3% de los productos anunciados eran no saludables (76,9% en 2017 y 75,8% en 2020; p = 0,86). Conclusiones: El perfil nutricional de los productos anunciados por televisión, mayoritariamente no saludables, no cambió tras la implantación del plan para mejorar su composición. Es preciso regular la publicidad alimentaria para proteger a los niños. (AU)

Objective: To compare the nutritional quality of the foods and beverages advertised on television in Spain, before and after the plan to improve their composition. Method: DTT broadcasts of the more popular channels were recorded in children's hours. Every advertised products in commercial breaks were registered and their nutritional data collected. We compared the distribution of frequencies by food categories and their adherence to the nutritional standards of the World Health Organization in 2017 and 2020. Results: In 256 h of broadcasting we identified 173 products (78 in 2017 and 95 in 2020). The most advertised products were chocolates (26.9% in 2017 and 22.1% in 2020). 76.3% of the products advertised were unhealthy (76.9% in 2017 vs. 75.8% in 2020; p = 0.86). Conclusions: The nutritional profile of the foods and drinks advertised on television, mostly unhealthy, did not change after the implementation of the plan to improve their composition. A regulation is needed to protect children from food advertising. (AU)

Effect of excise tax on sugar-sweetened beverages in Catalonia, Spain, three and a half years after its introduction.

BACKGROUND: The World Health Organisation urges countries to levy specific excise taxes on SSBs. Currently, more than 50 countries have introduced some type of tax on SSBs. In March 2017, the Autonomous Region of Catalonia approved the introduction of a tiered excise tax on SSBs for public health reasons. To evaluate the effect of the Catalonian excise tax on the price and purchase of sugar-sweetened beverages (SSBs) and their possible substitutes, i.e., non-sugar-sweetened beverages (NSSBs) and bottled water, three and half years after its introduction, and 1 year after the outbreak of the COVID-19 pandemic. METHODS: We analysed purchase data on soft drinks, fruit drinks and water, sourced from the Ministry of Agriculture food-consumption panel, in a random sample of 12,500 households across Spain. We applied the synthetic control method to infer the causal impact of the intervention, based on a Bayesian structural time-series model which predicts the counterfactual response that would have occurred in Catalonia, had no intervention taken place. RESULTS: As compared to the predicted (counterfactual) response, per capita purchases of SSBs fell by 0.17 l three and a half years after implementing the SSB tax in Catalonia, a 16.7% decline (95% CI: - 23.18, - 8.74). The mean SSB price rose by 0.11 €/L, an 11% increase (95% CI: 9.0, 14.1). Although there were no changes in mean NSSB prices, NSSB consumption rose by 0.19 l per capita, a 21.7% increase (95% CI: 18.25, 25.54). There were no variations in the price or consumption of bottled water. The effects were progressively greater over time, with SSB purchases decreasing by 10.4% at 1 year, 12.3% at 2 years, 15.3% at 3 years, and 16.7% at three and a half years of the tax's introduction. CONCLUSIONS: The Catalonian SSB excise tax had a sustained and progressive impact over time, with a fall in consumption of as much as 16.7% three and half years after its introduction. The observed NSSB substitution effect should be borne in mind when considering the application of this type of tax to the rest of Spain.

Characterization of occupational sensitization by multiallergen immunoblotting in workers exposed to laboratory animals.

BACKGROUND: Studies have estimated that 10% to 23% of workers exposed to laboratory animals report symptoms of laboratory animal allergy. OBJECTIVES: To determine the level of occupational sensitization in workers exposed to laboratory animals and to develop a diagnosis system based on a multiallergen IgE immunoblot. METHODS: A total of 75 workers exposed to laboratory animals were initially studied with skin prick tests performed with animal epithelia extracts. The workers with suspected occupational disease and positive skin prick test results were further studied with the ImmunoCAP system to determine specific IgE levels to urine and epithelia allergens and with multiallergen IgE immunoblotting to detect specific IgE levels to epithelia allergens and bovine serum albumin. RESULTS: Twenty of the 75 workers were studied with ImmunoCAP and multiallergen IgE immunoblotting. Nine were polysensitized and 3 were sensitized to only one animal. The results obtained by ImmunoCAP and multiallergen IgE immunoblotting were concordant except for in 3 workers, who had low or negative values of specific IgE determined by ImmunoCAP but positive allergen detections by immunoblotting. On the basis of the results of the study and the clinical symptoms related by workers, 16% were diagnosed as having occupational allergy. CONCLUSIONS: Multiallergen immunoblotting by means of a unique test offers a graphic representation of sensitization to the different animals to which workers are exposed, providing additional information on the clinical symptoms caused by the involved allergens. The results presented suggest that this system can improve the diagnosis of laboratory animal allergy by obtaining a sensitization profile for each exposed worker.
