Public health experts raise concerns about adolescents' and black youth's greater exposure to TV advertising for unhealthy foods and beverages compared with children and white youth.
Examine how television-viewing patterns and rates of advertising during targeted programming contribute to this greater exposure.
Nielsen panel data provided viewing times and amount of food advertising viewed on U.S. television in 2008 and 2012. Researchers compared results by network type (black-, child- and youth-targeted), age group (preschoolers, children and adolescents) and race (black and white youth).
Food advertising exposure increased with age for both black and white youth, but black youth viewed approximately 50% or more ads than did white youth of the same age. Higher rates of food advertising on youth-targeted networks explained greater adolescent exposure. However, greater television viewing and higher rates of advertising on youth- and black-targeted networks both contributed to black youth's greater exposure. From 2008 to 2012, increases in food-ads-per-hour increased exposure for all youth.
Food advertisers and networks, especially those targeting adolescents and black youth, must do more to reduce advertising that negatively impacts young people's health. Furthermore, reducing commercial-television viewing by black youth may help reduce health disparities affecting their communities.
公共卫生专家对青少年和黑人青年比儿童和白人青年更多地接触不健康食品和饮料的电视广告表示担忧。
研究在特定节目时段的观看模式和广告投放率如何导致这种更多的接触。
尼尔森面板数据提供了2008年和2012年美国电视上的观看时间和食品广告观看量。研究人员按网络类型（针对黑人、儿童和青年）、年龄组（学龄前儿童、儿童和青少年）和种族（黑人青年和白人青年）对结果进行了比较。
黑人和白人青年的食品广告接触量均随年龄增长而增加，但黑人青年比同年龄的白人青年观看的广告多约50%或更多。针对青年的网络上更高的食品广告投放率解释了青少年更多的接触量。然而，在针对青年和黑人的网络上更多的电视观看时间和更高的广告投放率都导致了黑人青年更多的接触量。从2008年到2012年，每小时食品广告数量的增加增加了所有青年的接触量。
食品广告商和网络，尤其是那些针对青少年和黑人青年的，必须采取更多措施减少对年轻人健康有负面影响的广告。此外，减少黑人青年观看商业电视可能有助于减少影响他们社区的健康差距。
