This paper examines the ways in which adolescents altered the type and size of their purchases of sugar-sweetened beverages (SSBs) in response to an intervention in six corner stores located in lower-income, predominately black neighborhoods in Baltimore, Maryland. Researchers used one of four randomly posted signs with caloric information about a 20 ounce SSB: 1) absolute calories; 2) number of teaspoons of sugar; 3) number of minutes running needed to burn it off; or 4) miles of walking necessary to burn it off. They collected the purchase data of a sample of black adolescents between ages 12 and 18. Researchers found that providing easy-to-understand caloric information significantly reduced the number of total beverage calories purchased (203 calories vs. 184 calories), the likelihood of buying a SSB (98% vs. 89%), and the likelihood of buying a SSB greater than 16 ounces (54% vs. 37%). They also found that the purchasing behaviors persisted for six weeks after the signs were removed. The reduction in calories purchased can be attributed to adolescents purchasing fewer sodas (44% vs. 30%) and sport drinks (3% vs. 1%) and purchasing more water (1% vs. 4%) and diet sodas (0.01% vs. 1%) as a result of the intervention.
Reducing Sugar-Sweetened Beverage Consumption by Providing Caloric Information: How Black Adolescents Alter Their Purchases and Whether the Effects Persist
Sugar-sweetened beverages (SSB) are an important contributor to adolescent obesity. One promising environmental strategy to reduce consumption of SSBs is to provide consumers with easily understandable caloric information. This infographic examines the effect of in-store calorie signage on adolescent sugary drink purchases. Findings presented in this infographic come from a … More
Providing easily understandable caloric information may be a low-cost strategy for lowering overall caloric intake among groups at high risk for obesity, particularly Black and Hispanic adolescents ages 12 to 18. The aims of the study are to: 1) examine if providing caloric information on sugar-sweetened beverages (SSBs) significantly reduces … More
Drinking water access in California schools: Room for improvement following implementation of school water policies
This study aimed to investigate how access to free drinking water in California public schools changed after implementation of 2010 federal and state school water policies. Repeated cross-sectional surveys were conducted with administrators in a random sample of California public schools, stratified by school type and urban-centric geography, from 2010 … More
