Unhealthy food advertising. A position paper by the AEP Committee on Nutrition and Breastfeeding.

INTRODUCTION: Some important factors influencing and maintaining unhealthy habits are food advertising and products accessibility. In order to develop and support recommendations, an analysis of the available evidence on the impact of food advertising on the health of children and adolescents has been carried out. METHODS: Literature review of systematic reviews and meta-analyses published up to January 2022 for the term "food advertising" that analyzed the impact of food advertising on weight, body mass index (BMI), adiposity, dietary intake, behavior toward the advertised product, its purchase or consumption in children and adolescents. RESULTS: Twenty-one systematic reviews fulfilled the inclusion criteria, including a total of 490 primary studies, 5 of which also contained a meta-analysis. The vast majority of the primary studies evaluate intermediate effects, related to the behavior of children and adolescents in relation to advertised products and their consumption. There is great variety in terms of the type of advertising and effects studied. Most of the studies agree that there is an association between food advertising and effect analyzed, being more evident in children under 12 years of age and in obese children. Most recent systematic reviews are focused on online advertising, noticing the negative effects especially in adolescents. CONCLUSIONS: Children and adolescents are a particularly vulnerable population to food advertising strategies. Despite the difficulty to demonstrate an independent effect, there is evidence of an association between food advertising and childhood and adolescents' behavior respect to the announced products, and the increase of consumption at short-term. In Spain unhealthy product advertising are still very common in the media and in the children and adolescent's online environment. The Nutrition and Breastfeeding Committee of the Spanish Association of Pediatrics supports the need for regulation and limitation of unhealthy food advertising, covering all media and marketing strategies.

Chylomicron Retention Disease: a Description of a New Mutation in a Very Rare Disease.

Chylomicron retention disease, also known as Anderson's disease, is a rare hereditary hypocholesterolemic disorder, recessive inherited, characterized by nonspecific symptoms as abdominal distension, steatorrhea, and vomiting associated with failure to thrive. We describe a patient with failure to thrive, chronic diarrhea and steatorrhea who the diagnosis of chylomicron retention disease was established after several months of disease progression. The genetic study confirmed a homozygosity mutation in SAR1B gene, identifying a mutation never previous described [c.83_84delTG(p.Leu28Argfs*7)]. With this case report the authors aim to highlight for this very rare cause of failure to thrive and for the importance of an attempting diagnosis, in order to start adequate management with low fat diet supplemented with fat-soluble vitamins, reverting the state of malnutrition and avoiding possible irreversible and desvantating complications.
