BACKGROUND: The Chilean government implemented the first phase of a comprehensive marketing policy in 2016, restricting child-directed marketing of products high in energy, total sugars, sodium or saturated fat (hereafter "high-in"). OBJECTIVES: To examine the role that high-in TV food advertising had in the effect of the policy on consumption of high-in products between 2016 and 2017. METHODS: Dietary data were obtained from 24-hour diet recall measured in 2016 (n=940) and 2017 (n=853), pre- and post-policy, from a cohort of 4–6 y children. Television use was linked to analyses of food advertisements to derive individual-level estimates of exposure to advertising. A multilevel mediation analysis examined direct and indirect effects of the policy through advertising exposure. RESULTS: Children's high-in food consumption and advertising exposure declined significantly from 2016 to 2017 (p<0.01). Consumption changes were not significantly mediated by changes in advertising exposure, which might suggest other elements of the Chilean Law potentially driving decreases in consumption to a greater extent than TV ads. CONCLUSIONS: Preschoolers' exposure to high-in advertising and consumption of high-in products decreased post-policy. Further research is needed to understand how marketing changes will relate to dietary changes after full implementation of the law and in the long term.
Restricting children's exposures to marketing of unhealthy foods and beverages is a global obesity prevention priority. Monitoring marketing exposures supports informed policymaking. This study presents a global overview of children's television advertising exposure to healthy and unhealthy products. Twenty-two countries contributed data, captured between 2008 and 2017. Advertisements were coded for the nature of foods and beverages, using the 2015 World Health Organization (WHO) Europe Nutrient Profile Model (should be permitted/not-permitted to be advertised). Peak viewing times were defined as the top five hour timeslots for children. On average, there were four times more advertisements for foods/beverages that should not be permitted than for permitted foods/beverages. The frequency of food/beverages advertisements that should not be permitted per hour was higher during peak viewing times compared with other times (P < 0.001). During peak viewing times, food and beverage advertisements that should not be permitted were higher in countries with industry self-regulatory programmes for responsible advertising compared with countries with no policies. Globally, children are exposed to a large volume of television advertisements for unhealthy foods and beverages, despite the implementation of food industry programmes. Governments should enact regulation to protect children from television advertising of unhealthy products that undermine their health. ; International Development Research Center, Grant/Award Numbers: 107459‐001, 107731, 107213001 and 107731‐002; Javna Agencija za Raziskovalno Dejavnost RS; Spanish Health Research Fund of the Institute of Health Carlos III, Grant/Award Number: ENPY 1015/13; Wellcome Trust; National Institute for Health Research; Medical Research Council; Economic and Social Research Council; Cancer Research UK; British Heart Foundation; Spanish Consumers Organization (OCU); Slovenian Research Agency and Ministry of Health of Republic of Slovenia, Grant/Award Number: P3‐0395; Ministry of Higher Education, Grant/Award Number: FRGS/1/2013/ SS03/UKM/02/5; Estrategia de sostenibilidad de grupos de investigación. ; Sí
