This paper provides some disturbing facts and figures about the amount of television being watched by children. In addition, it reports on the volume and type of television advertising aimed at young people, both in the United Kingdom and other developed countries. In view of recent public and professional concern as to the possible adverse effects of food advertising on children's health, this study set out to examine what proportion of television advertisements, directed at children, promoted products potentially harmful to dental health. Forty-one hours of children's television programming broadcast on ITV1, the main UK commercial channel, were recorded on to videotape for subsequent analysis. Almost 1,000 adverts were analysed; each was timed and broadly categorised as relating to a food/drink product or non food/drink product. Advertisements for food and drink were further subdivided according to their sugar and/or acid content. We found that, on average, 24 adverts were shown per broadcast hour, which accounted for 15.8% of the total schedule time. 34.8% of adverts related to food/drink products, and 95.3% of these promoted products that were deemed potentially cariogenic or erosive. The most frequently promoted food/drink products included breakfast cereals with added sugar (26.3%), confectionery (23.7%) and non-carbonated soft drinks (18.1%). It is very concerning that, despite recent specific codes of practice outlined by the Independent Television Commission for Children's Advertising, many food and drink products promoted during children's programming are potentially damaging to dental health.
本文提供了一些关于儿童看电视时长的令人不安的事实和数据。此外,它还报道了英国和其他发达国家针对年轻人的电视广告的数量和类型。鉴于近期公众和专业人士对食品广告可能对儿童健康产生的不利影响表示关注,本研究着手调查针对儿童的电视广告中,宣传对牙齿健康有潜在危害产品的广告所占比例。在英国主要商业频道独立电视一台(ITV1)播出的41小时儿童电视节目被录制到录像带上,以便后续分析。对近1000条广告进行了分析;每条广告都记录了时长,并大致归类为与食品/饮料产品或非食品/饮料产品相关。食品和饮料广告根据其糖和/或酸含量进一步细分。我们发现,平均每播出小时有24条广告,占总节目时间的15.8%。34.8%的广告与食品/饮料产品有关,其中95.3%宣传的产品被认为有潜在致龋性或腐蚀性。最常宣传的食品/饮料产品包括加糖早餐谷物(26.3%)、糖果(23.7%)和非碳酸软饮料(18.1%)。令人非常担忧的是,尽管独立电视委员会近期针对儿童广告制定了具体的行为准则,但在儿童节目中宣传的许多食品和饮料产品都可能对牙齿健康造成损害。
