目的：研究2 - 11岁儿童接触电视食品广告的情况。设计：使用电视收视率数据对全国性广告分布进行加权检验。设置：从2003年9月1日至2004年5月31日，2 - 11岁儿童观看的170个收视率最高的电视节目中的全国性广告。参与者：224083个广告的样本。主要结局指标：电视非节目内容时间在6个相互排斥的类别中进行了评估，包括食品、非快餐店、快餐店、其他产品、公共服务公告和电视促销。食品广告进行了评估，根据7个食品类别-谷物，零食，糖果，饮料，快餐店，非快餐店，和其他食品-然后检查在更详细的categories.Results：在2003-2004年，27.2%和36.4%的儿童的接触总nonprogram内容的时间和产品广告，分别为食品相关的产品。种族分布相似。谷物是最常见的食品，占所有食品广告的27.6%。与以往的研究比较表明，随着时间的推移，食品广告占较小的份额，看到的产品广告由US children.Conclusions：2岁至11岁的儿童接触到大量的食品广告，通过电视，但在过去的几十年中，儿童肥胖率的急剧增加并没有反映在食品广告曝光的类似变化。然而，我们发现的证据表明，最近（2000年至2005年）在美国儿童中接触电视食品广告的数量呈上升趋势。
Objective: To examine exposure to food advertising on television (TV) among children aged 2 through 11 years.Design: Weighted examination of the distribution of national advertisements (ads) using TV ratings data.Setting: National ads from 170 top-rated TV shows viewed by children aged 2 through 11 years from September 1, 2003, through May 31, 2004.Participants: Sample of 224 083 ads. Main OutcomeMeasures: Television nonprogram content time was assessed across 6 mutually exclusive categories that included food products, non-fast food restaurants, fast food restaurants, other products, public service announcements, and TV promotions. Food advertising was assessed according to 7 food categories-cereal, snacks, sweets, beverages, fast food restaurants, non-fast food restaurants, and other food products-and then examined across more detailed categories.Results: In 2003-2004, 27.2% and 36.4% of children's exposure to total nonprogram content time and product advertising, respectively, was for food-related products. Similar distributions were found by race. Cereal was the most frequently seen food product, making up 27.6% of all food ads. Comparisons with previous studies suggest that, over time, food ads account for a smaller share of the product ads seen by US children.Conclusions: Children aged 2 through 11 years are exposed to a substantial amount of food advertising through TV, but the dramatic increase in childhood obesity rates during the past few decades was not mirrored by similar changes in food advertising exposure. However, we found evidence of a very recent (2000-2005) upward trend in the amount of exposure to food advertising on TV among US children.
