Though 84% of Americans say childhood obesity is a "major problem," only half of respondents to a recent Wall Street Journal survey believe the government should regulate advertising and marketing messages aimed at kids. And, only 55% of respondents say the government should prosecute firms that mislead children and their parents about the nutritional value of the foods they sell.

The survey reveals a growing seriousness among Americans about childhood obesity. In last year's survey, only 77% of respondents characterized childhood obesity as a "major problem."

In the latest survey, 83% of respondents said public schools should limit kids' access to unhealthy foods, and 81% say parents don't pay enough attention to their kids' eating habits. And, 65% said they believe that advertising contributes to increased childhood obesity rates.
