The Cato Institute held a policy forum this week entitled “Kids, Cartoons and Cookies: Should We Restrict the Marketing of Food to Children?” I participated (PowerPoint link) on the panel along with Dale Kunkel, Professor of Communication at the University of California-Santa Barbara; and Todd Zywicki, Director of the FTC’s Office of Policy Planning.
Mr. Zywicki and I separately presented important new data that helps demonstrate that food advertising should not be linked to rising obesity rates in the United States. Mr. Zywicki’s presentation tested the hypothesis presented by some critics that increased advertising exposure has led to increased obesity rates. His analysis looked at a number of factors, including whether children are watching more television and thus seeing more ads; whether children are seeing more ads per hour of programming; and whether the mixture of ads has changed in composition so that more food ads are being shown. His research found that television viewing and the number of ads per hour has gone down, while ad composition has remained constant. He also examined whether parents are just “giving in” to their children’s demands. His research found that children tend to eat what their parents eat, leading him to conclude that parents still have control over food choice. Mr. Zywicki emphasized, as most analysts do, that obesity problems are caused by multiple factors. He also emphasized that banning ads would be “impractical, ineffective, and illegal.”
I later presented an analysis drawn from a study carried out for the ANA and the Grocery Manufacturers of America (GMA). This study analyzed data provided by Nielsen Media Research covering the period 1993 to 2003. This ten year period has been cited as the time in which obesity rates grew the most and at the fastest rate.
The study drew the following conclusions:
1) Adjusting for inflation in order to hold the value of dollars constant over the time period, real expenditures on food and restaurant advertising on all television, including cable, fell over the ten year period 1993-2003;
2) Rather than being increasingly bombarded by restaurant and food advertising, kids 12 and under, in fact, saw less food and restaurant ads between 1993 and 2003;
3) Therefore, obesity rates in the U.S. cannot be blamed either on the increase in expenditures or the quantity of ads for food and restaurants viewed by kids 12 and under.
The following tables and explanatory material provide more detail in regard to these findings (click on the thumbnails to view).
This chart shows that total spending on food and restaurant ads over the ten year study period reached $5.92 billion in 1994, and fell to $4.98 billion in 2003. Annual expenditures over the last four years of the survey period, from 2000 to 2003, averaged $4.92 billion per year. In comparison, over the first four years of the survey period, from 1993 to 1996, ad spending averaged $5.60 billion per year.
This chart shows that the number of ads seen by children under 12 declined in the same ten year period. The number of ads reached 5,909 per year in 1994 and dropped to 5,038 in 2003. There was a decline of 13% when the last four years are compared to the first four years of the period.
This final chart expands on the second chart to show how many commercials were for foods and how many were for restaurants. It shows that the commercials directed at children for restaurants have remained relatively constant, and that overall; the trend for these ads is down.
These data are consistent with the experience of other countries where bans or severe restrictions on children’s advertising have failed to lower obesity rates in comparison to nearby countries where there are no restrictions on advertising to children.
These data also provide a strong foundation of facts to answer those who see banning or severely restricting ads as the solution to the obesity problem.
