Television advertisements for less healthy foods are thought to contribute to overweight and obesity in children. In the UK, new regulations on television food advertising to children came into effect in April 2007. These prohibit advertisements for "less healthy" foods during or around programmes "of particular appeal to" (OPAT) children. In Canada, self-regulated codes of practice on television food advertising to children were recently strengthened.
To document the nutritional content of food advertised and number of advertisements OPAT children broadcast in the UK and central Canada before the introduction of the new UK regulations.
All food advertisements broadcast on four popular channels in Canada and the three terrestrial commercial channels in the UK during 1 week in 2006 were identified and linked to relevant nutritional data. Food advertisements OPAT children and for "less healthy" products were identified using the criteria in the UK regulations.
2315 food related advertisements broadcast in Canada and 1365 broadcast in the UK were included. 52-61% were for "less healthy" products; 5-11% were OPAT children. Around 5% of food advertisements would have been prohibited under the new UK regulations. There were few differences in the nutritional content of food described in advertisements that were and were not OPAT children.
There was little evidence that food described in advertisements OPAT children were any less healthy than those that were not. Few food advertisements are likely to be prohibited by the new UK regulations.
人们认为,针对儿童的不健康食品电视广告会导致儿童超重和肥胖。在英国,针对儿童的电视食品广告新规定于2007年4月生效。这些规定禁止在“特别吸引”(OPAT)儿童的节目期间或前后播放“不健康”食品的广告。在加拿大,最近加强了针对儿童的电视食品广告自律规范。
记录在英国新规定出台之前,英国和加拿大中部播放的面向OPAT儿童的食品广告的营养成分以及广告数量。
确定了2006年某一周内在加拿大四个热门频道和英国三个地面商业频道上播放的所有食品广告,并将其与相关营养数据关联起来。根据英国规定中的标准,确定了面向OPAT儿童的食品广告和“不健康”产品的广告。
纳入了在加拿大播放的2315条与食品相关的广告和在英国播放的1365条广告。52% - 61%的广告是针对“不健康”产品的;5% - 11%的广告是面向OPAT儿童的。根据英国的新规定,大约5%的食品广告会被禁止。面向OPAT儿童的广告和非面向OPAT儿童的广告中所描述食品的营养成分几乎没有差异。
几乎没有证据表明,面向OPAT儿童的广告中所描述的食品比其他广告中的食品更不健康。英国的新规定可能只会禁止少数食品广告。
