Advertising of foods and beverages in social media aimed at children: high exposure and low control.

BACKGROUND: This work is aimed to describe the recent scientific literature developed in the food/beverage sector and social networks aimed at children and adolescents, as well as current regulations. METHODS: A rapid review of the studies on advertising and social media aimed at children, published from 2010 tp 2020 is carried out, following the established inclusion criteria. In addition, the regulations in the countries in which the studies were carried out were also reviewed. RESULTS: Of the 573 articles, 7 met these criteria. The great attraction of unhealthy foods for children is observed, who remembered and recognized a greater number of unhealthy food brands and, by extension, the ability to influence of communication in social networks. Each country has its own self-regulation, two (Ireland and USA) have legislation on children's food advertising, and Australia has legislation that applies only to open television. However, none of the analyzed countries have specific regulations on food, children and media advertising. CONCLUSIONS: Given the fact that there is evidence about the great attraction that social networks suppose for the child, that they are a stimulus for the consumption of food and that many of these foods are harmful to their health; we should work in two directions: 1) Promote public policies based on promoting healthy habits among minors; and 2) Monitor and implement regulations in commercial communication social media.

Hábitos alimentarios y rendimiento académico en escolares chilenos de quinto a octavo año básico

RESUMEN Introducción: Los hábitos alimentarios en escolares se han relacionado con las habilidades cognitivas y el rendimiento académico. Objetivo: Determinar la relación entre hábitos alimentarios y rendimiento académico en escolares chilenos. Métodos: Estudio transversal en 733 escolares de quinto al octavo básico. Se evaluaron hábitos alimentarios mediante frecuencia de consumo de grupos de alimentos, tiempos de comida, habilidades culinarias y gusto por preparar alimentos. Estas variables se relacionaron con calificaciones de las asignaturas de matemática y lenguaje. Resultados: Los escolares presentaron baja proporción de frecuencia de consumo saludable (FCS). Las niñas presentaron mayor FCS de pan (p<0,001), los niños presentaron mayor FCS de lácteos (p= 0,016). Por sexo, se observó diferencia en el rendimiento académico en lenguaje (p= 0,013). La FCS de lácteos se asoció con diferencias del rendimiento académico en lenguaje (p= 0,017) y matemática (p= 0,035). Desayunar se asoció a diferencias en el rendimiento académico en matemática (p= 0,028) y lenguaje (p= 0,001). No consumir pasteles y masas dulces (p= 0,016), y papas fritas, completos y masas fritas (p= 0,025) se asoció al rendimiento académico en matemática. Un 29,1% tiene habilidades culinarias, siendo 54% niñas (p= 0,006). La presencia de habilidades culinarias se relacionó significativamente con 7 de los 12 grupos de alimentos analizados. Conclusión: Los hábitos alimentarios se asociaron con el rendimiento académico de escolares.

ABSTRACT Introduction: Eating habits in school-age children have been associated with cognitive skills and academic performance. Aim: To determine the relationship between eating habits and academic performance in Chilean school-age children. Methods: Cross-sectional study with 733 school-age children. Eating habits were assessed by the frequency of consumption of food groups, mealtimes, cooking skills and if they liked to cook. Grades of math and language subjects were reported. Results: There was a low proportion of healthy consumption frequency (HCF). Girls had a higher HCF of bread (p<0.001), boys had a higher HCF of dairy (p= 0.016). By sex, academic performance in language was different in girls (p= 0.013). HCF of dairy was associated with academic performance in language (p= 0.017) and mathematics (p= 0.035). Eating breakfast was associated with academic performance in mathematics (p= 0.028) and language (p= 0.001). Not consuming cakes and sweet doughs (p= 0.016), French fries, hot dogs and sopaipillas (p= 0.025) was associated with academic performance in mathematics. 29.1% of children had cooking skills, 54.0% being girls (p= 0.006). Having cooking skills was significantly associated with 7 of the 12 food groups analyzed. Conclusion: Eating habits are associated to the academic performance of Chilean school-age children.

Actitudes de madres de preescolares ante la implementación de la ley de etiquetado nutricional en Chile / Attitudes of mothers of preschools in the implementation of the nutritional labeling law in Chile

Debido a los cambios en los estilos de vida y su reflejo en la prevalencia de malnutrición por exceso a nivel mundial, en Chile (2016) se aprobó la Ley sobre Composición de los Alimentos y su Publicidad. El objetivo de este estudio fue determinar las actitudes alimentarias en madres de preescolares de distinto nivel socioeconómico y el estado nutricional de sus hijos, frente a la publicidad de alimentos y bebidas a través de distintas formas de promoción comercial, así como su actitud ante la Ley 20.606. Se aplicó una encuesta validada, la cual incluye preguntas sobre las etiquetas en los envases de los alimentos. Se realizó un análisis descriptivo de las variables y se determinó si existía diferencias entre la distribución de las respuestas según NSE mediante la prueba Chi2 .Al consultar los lugares en los que han visto publicidad de alimentos, 72% de las madres refiere haberla visto en los supermercados y 48,5% en internet. Sólo 34, 8% refirió recordar algún comercial en particular, y al solicitarles que especificaran el comercial que recordaban, 45,3% nombró alguna bebida azucarada y 13,6% alguna de yogurt. Respecto a los sellos de advertencia presentes en los envases de los alimentos, 87% declaró que les gustaban o les parecían bien. Sólo 43,6% respondió que había dejado de comprar alimentos con dichos sellos. Estos resultados serán útiles para el diseño de intervenciones específicas para este importante grupo, ya que un cambio positivo en sus conductas actuales podría repercutir en la creación de hábitos saludables en sus hijos e hijas(AU)

Due to changes in lifestyles and its reflection on the worldwide prevalence of malnutrition due to excess, in Chile (2016) the Law on Food Composition and its Advertising was approved. The objective of this study was to determine the nutritional attitudes of 509 mothers of preschoolers of different socioeconomic levels and the nutritional status of their children, in front of the advertising of food and beverages through different forms of commercial promotion, as well as their attitude towards Law 20,606. A validated survey was applied, which includes questions about labels on food containers. A descriptive analysis of the variables was carried out to determine if there were differences between the distributions of the responses according to the SEL using the Chi2 test. When consulting the places where they have seen the food advertising, 72% of the mothers reported having seen it in the supermarkets and 48.5% on the internet. Only 34, 8% reported to remembering a particular commercial, and when asked to specify the commercial they remembered, 45.3% named a sugary drink and 13.6% some yogurt. Regarding the warning seals present on food containers, 87% stated that they liked them or they seemed good to them. Only 43.6% answered that they have stopped buying foods with these labels. These results will be useful for the design of specific interventions for this important group, since a positive change in their current behaviors could have an impact on the creation of healthy habits in their children(AU)

Does the scientific evidence support the advertising claims made for products containing Lactobacillus casei and Bifidobacterium lactis? A systematic review.

BACKGROUND: To analyse the scientific evidence that exists for the advertising claims made for two products containing Lactobacillus casei and Bifidobacterium lactis and to conduct a comparison between the published literature and what is presented in the corporate website. METHODS: Systematic review, using Medline through Pubmed and Embase. We included human clinical trials that exclusively measured the effect of Lactobacillus casei or Bifidobacterium lactis on a healthy population, and where the objective was related to the health claims made for certain products in advertising. We assessed the levels of evidence and the strength of the recommendation according to the classification criteria established by the Oxford Centre for Evidence Based Medicine (CEBM). We also assessed the outcomes of the studies published on the website that did not appear in the search. RESULTS: Of the 440 articles identified, 16 met the inclusion criteria. Only four (25%) of these presented a level of evidence of 1b and a recommendation grade of A, all corresponding to studies on product containing Bifidobacterium lactis, and only 12 of the 16 studies were published on the corporate website (47). CONCLUSIONS: There is insufficient scientific evidence to support the health claims made for these products, especially in the case of product containing Lactobacillus casei.
