Efecto de la publicidad de alimentos anunciados en la televisión sobrela preferencia y el consumo de alimentos: revisión sistemática / Effect of food television advertising on the preference and food consumption: systematic review

Objetivo: El propósito de esta revisión sistemática es evaluar estudios acerca del efecto de los anuncios de alimentos en TV sobre las preferencias y el consumo de alimentos en diferentes grupos de edad. Métodos: Se realizó una búsqueda de ensayos aleatorios controlados publicados en Pubmed, Ebsco, Cochrane, Scielo hasta Noviembre del 2010. Se incluyeron aquéllos que evaluaran el efecto de la exposición directa a anuncios de alimentos en TV sobre las preferencias, demanda, compra y consumo. Resultados: Diez estudios cumplieron con los criterios de inclusión. En los tres estudios que evaluaron el efecto de la exposición a anuncios de alimentos en preescolares se observó un aumento en la selección y demanda de los alimentos. Todos los cinco estudios realizados en escolares presentaron resultados negativos en los expuestos a alimentación no saludable. De los tres estudios realizados en adultos, dos reportaron un mayor consumo de los alimentos anunciados en el grupo expuesto. Conclusión: Los estudios evaluados demuestran que en preescolares y escolares el efecto de los anuncios sobre el consumo de alimentos es consistente, mientras que en adultos los resultados apuntan hacia una fuerte asociación entre la exposición a los anuncios de alimentos en TV con la preferencia, consumo y demanda por los alimentos anunciados (AU)

Objective: The aim of this study was to perform a systematic review of papers that assess the effect of television food advertisings (TFA) in the food preferences and consumption in different age groups. Methods: Randomized clinical trials published up to November 2010 were searched in Pubmed, Ebsco, Cochrane and Scielo. Studies were included if they assessed the effect of direct exposition to TFA over the food preferences, demand, and consumption. Results: Ten studies fulfilled the inclusion criteria. In the three studies conducted on preschooler children an increase in selection and demand of advertized foods was reported. All the fives studies conducted on scholar children reported negative outcomes in those children exposed to unhealthy food. An increase on food consumption was observed in two of the three studies conducted on adults. Conclusion: The assess studies show that in preschool and school children the effect of advertising on food consumption was consistent, while in adults there is a trend toward an strong association of exposure food advertising and preference, consumption and demand of the food advertised (AU)
