Food advertising on TV and energy intake in children: Results from the OBEY-AD Mexico

Food advertising on TV is a common marketing practice, and it is suspected of promoting obesogenic behaviours. The study aimed at evaluating if gadgets (toys) packaged with food increase food consumption, and if contemporary exposure to TV and/or advertising is a further promoting factor. Onehundred and twenty children (balanced according to gender and age groups, 3-6 and 7-10 years old) were randomised in an experimental setting designed as a 2x5 full factorial ad libitum eating study. The first factor was represented by the exposure to gadgets, organized on two levels, "food with gadget" (TOY) and "food alone" (NoTOY). The second one consisted in the exposure to TV and advertising along five levels (no exposure to TV, exposure to TV without advertising, exposure to TV and 1, 2, or 3 advertsements). Our results showed no significant differences when considering the groups even after taking into account the dependent variables. The medium spot group showed the lowest energy intake, but the difference between the other groups was not significant. TV advertising and the presence of gadgets (toys) do not influence caloric intake in children
