Objective. To provide the most comprehensive analysis to date of the extent of food advertising on UK television channels popular with young people following regulatory reform of this type of marketing activity. Methods. UK television was recorded 06:00-22:00 h for a weekday and a weekend day every month between January and December 2008 for 14 of the most popular commercial channels broadcasting children's/family viewing. Recordings were screened for advertisements, which were coded according to predefined categories including whether they were broadcast in peak/non-peak children's viewing time. Food advertisements were coded as core (healthy)/non-core (unhealthy)/miscellaneous foods. Results. Food and drinks were the third most heavily advertised product category, and there were a significantly greater proportion of advertisements for food/drinks during peak compared to non-peak children's viewing times. A significantly greater proportion of the advertisements broadcast around soap operas than around children's programmes were for food/drinks. Children's channels broadcast a significantly greater proportion of non-core food advertisements than the family channels. There were significant differences between recording months for the proportion of core/non-core/miscellaneous food advertisements. Conclusions. Despite regulation, children in the UK are exposed to more TV advertising for unhealthy than healthy food items, even at peak children's viewing times. There remains scope to strengthen the rules regarding advertising of HFSS foods around programming popular with children and adults alike, where current regulations do not apply. Ongoing, systematic monitoring is essential for evaluation of the effectiveness of regulations designed to reduce children's exposure to HFSS food advertising on television in the UK.

Objective. To investigate the effects of weight status, food type and exposure to food and non-food advertisements on children's preference for branded and non-branded foods. Design. A within-subjects, counterbalanced design with control (toy advertisement) and experimental (food advertisement) conditions. Subjects. A total of 37 school students (age: 11-13 years; weight status: 24 lean, 10 overweight, 3 obese). Measurements. Advertisement recall list, two food preference measures; the Leeds Food Preference Measure (LFPM), the Adapted Food Preference Measure (AFPM) and a food choice measure; the Leeds Forced-choice Test (LFCT). Results. Normal weight children selected more branded and non-branded food items after exposure to food advertisements than in the control (toy advertisement) condition. Obese and overweight children showed a greater preference for branded foods than normal weight children per se, and also in this group only, there was a significant correlation between food advertisement recall and the total number of food items chosen in the experimental (food advertisement) condition. Conclusion. Exposure to food advertisements increased the preference for branded food items in the normal weight children. This suggests that television food advertisement exposure can produce the same 'obesigenic' food preference response found in overweight and obese children in their normal weight counterparts.
