目的：研究儿童在电视上接触食品相关广告的趋势，按年龄、产品类别和公司划分。设计：使用2003年、2005年、2007年和2009年儿童电视收视率数据进行营养内容分析。设置：年度特定年龄的电视收视率数据捕捉了儿童对广播网络、有线网络、辛迪加、从所有（西班牙语除外）节目中发现电视食品广告。参与者：2至5岁和6至11岁的儿童。主要接触：电视收视率。主要结局指标：儿童接触电视上与食品相关的广告，并对食品和饮料产品的饱和脂肪、糖、纤维和钠的毫克数进行营养评估。结果：2009年，2至5岁及6至11岁儿童平均每天分别收看10.9及12.7则与食物有关的电视广告，较2003年分别减少17.8%及6.9%。2003年至2009年，2至5岁和6至11岁的儿童接触高饱和脂肪、糖或钠的食品和饮料产品的比例分别下降了37.9%和27.7%，但快餐广告的比例分别增加了21.1%和30.8%。2009年，86%的儿童看到的广告是高饱和脂肪，糖或钠的产品，从2003年的94%下降。结论：接触不健康的食品和饮料产品广告已经下降，而接触快餐广告从2003年到2009年增加。到2009年，美国儿童继续在电视上看到的食品和饮料广告的营养成分没有实质性的改善。
Objective: To examine trends in children's exposure to food-related advertising on television by age, product category, and company.Design: Nutritional content analysis using television ratings data for 2003, 2005, 2007, and 2009 for children.Setting: Annual age-specific television ratings data captured children's exposure to broadcast network, cable network, syndicated, and spot television food advertising from all (except Spanish-language) programming.Participants: Children aged 2 to 5 and 6 to 11 years.Main Exposure: Television ratings. Main Outcome Measures: Children's exposure to food-related advertising on television with nutritional assessments for food and beverage products for grams of saturated fat, sugar, and fiber and milligrams of sodium.Results: Children aged 2 to 5 and 6 to 11 years saw, respectively, on average, 10.9 and 12.7 food-related television advertisements daily in 2009, down 17.8% and 6.9% from 2003. Exposure to food and beverage products high in saturated fat, sugar, or sodium fell 37.9% and 27.7% but fast-food advertising exposure increased by 21.1% and 30.8% among 2-to 5- and 6- to 11-year-olds, respectively, between 2003 and 2009. In 2009, 86% of ads seen by children were for products high in saturated fat, sugar, or sodium, down from 94% in 2003.Conclusions: Exposure to unhealthy food and beverage product advertisements has fallen, whereas exposure to fast-food ads increased from 2003 to 2009. By 2009, there was not a substantial improvement in the nutritional content of food and beverage advertisements that continued to be advertised and viewed on television by US children.
