[BDSP. Notice produite par INIST-CNRS pR0x8BA9. Diffusion soumise à autorisation]. Objectives. We examined the effect of an intervention to provide caloric information about sugar-sweetened beverages (SSBs) on the number of SSB purchases. Methods. We used a case-crossover design with 4 corner stores located in low-income, predominately Black neighborhoods in Baltimore, Maryland. The intervention randomly posted 1 of 3 signs with the following caloric information : (1) absolute caloric count, (2) percentage of total recommended daily intake, and (3) physical activity equivalent. We collected data for 1600 beverage sales by Black adolescents, aged 12-18 years, including 400 during a baseline period and 400 for each of the 3 caloric condition interventions. Results. Providing Black adolescents with any caloric information significantly reduced the odds of SSB purchases relative to the baseline (odds ratio [OR]=0.56 ; 95 % confidence interval [CI]=0.36,0.89). When examining the 3 caloric conditions separately, the significant effect was observed when caloric information was provided as a physical activity equivalent (OR =0.51 ; 95 % CI =0.31,0.85). Conclusions. Providing easily understandable caloric information-particularly a physical activity equivalent-may reduce calorie intake from SSBs among low-income, Black adolescents.
