50 Minutes to Burn Soda: New Ads Cut Drink Purchases Among Black Teens

By    |   Tuesday, 21 Oct 2014 08:32 AM

It takes 50 minutes of running to burn off the calories in a sugary soda, and researchers say  turning that fact into a message to young people helps reduce their intake.

"People don't really understand what it means to say a typical soda has 250 calories," said Sara N. Bleich, PhD, an associate professor at the Johns Hopkins University Bloomberg School of Public Health research.

"If you're going to give people calorie information, there's probably a better way to do it. What our research found is that when you explain calories in an easily understandable way such as how many miles of walking needed to burn them off, you can encourage behavior change."

Bleich and her colleagues conducted a series of behavioral experiments in low-income, predominantly black Baltimore neighborhoods for six-week increments between August 2012 and June 2013. The finding so the study were published online October 16 in the American Journal of Public Health.

By placing fours signs in local corner stores explaining that a 20-ounce bottle of soda, sports drinks, or fruit juice requires 50 minutes of running or 5 miles of walking to burn off, researchers observed that sugary drink purchases — which initially accounted for 98 percent of drinks purchased in the store — dropped to 89 percent.

Moreover, of the roughly one-third of adolescents between the ages of 12 and 18 who saw one of the signs, 59 percent said they believed them and 40 percent said they changed their behavior.

"This is a very low-cost way to get children old enough to make their own purchases to drink fewer sugar-sweetened beverages and they appear to be effective even after they are removed," Bleich said in a statement following the publication of her research.

"Black adolescents are one of the groups at highest risk for obesity and one of the largest consumers of sugary beverages. And there is a strong scientific link between consumption of sugary beverages and obesity. Using these easy-to-understand and easy-to-install signs may help promote obesity prevention or weight loss."
