We compared television food advertising to children in several countries.
We undertook a collaboration among 13 research groups in Australia, Asia, Western Europe, and North and South America. Each group recorded programming for 2 weekdays and 2 weekend days between 6:00 and 22:00, for the 3 channels most watched by children, between October 2007 and March 2008. We classified food advertisements as core (nutrient dense, low in energy), noncore (high in undesirable nutrients or energy, as defined by dietary standards), or miscellaneous. We also categorized thematic content (promotional characters and premiums).
Food advertisements composed 11% to 29% of advertisements. Noncore foods were featured in 53% to 87% of food advertisements, and the rate of noncore food advertising was higher during children's peak viewing times. Most food advertisements containing persuasive marketing were for noncore products.
Across all sampled countries, children were exposed to high volumes of television advertising for unhealthy foods, featuring child-oriented persuasive techniques. Because of the proven connections between food advertising, preferences, and consumption, our findings lend support to calls for regulation of food advertising during children's peak viewing times.
我们比较了几个国家的电视食品广告对儿童的影响。
我们在澳大利亚、亚洲、西欧以及北美和南美 13 个研究小组之间开展了合作。每个小组在 2007 年 10 月至 2008 年 3 月期间,对儿童最常观看的 3 个频道,在每周工作日的 6:00 至 22:00 和周末的两天中,分别记录了两天工作日和两天周末的节目。我们将食品广告分为核心(营养密集、低热量)、非核心(高热量或营养成分不理想,按饮食标准定义)或杂项。我们还对主题内容(促销角色和赠品)进行了分类。
食品广告占广告的 11%至 29%。非核心食品在 53%至 87%的食品广告中出现,并且在儿童的高峰收视时段,非核心食品广告的比例更高。大多数含有有说服力的营销手段的食品广告都是针对非核心产品的。
在所有抽样国家中,儿童都暴露在大量针对不健康食品的电视广告中,这些广告都采用了针对儿童的有说服力的营销手段。由于食品广告、偏好和消费之间存在着已被证实的联系,我们的研究结果支持了在儿童高峰收视时段限制食品广告的呼吁。
