目标.我们研究了干预措施对含糖饮料（SSB）购买数量的影响。我们使用了案例交叉设计，在马里兰州的巴尔的摩，在低收入，主要是黑人社区的4个街角商店。干预措施随机张贴3个标志中的1个，并提供以下热量信息：（1）绝对热量计数，（2）每日总推荐摄入量的百分比，（3）体力活动当量。我们收集了1600名黑人青少年的饮料销售数据，年龄在12-18岁之间，包括400名基线期和400名3种热量条件干预。与基线相比，向黑人青少年提供任何热量信息均显著降低了购买SSB的几率（比值比[OR] = 0.56; 95%置信区间[CI]=0.36，0.89）。当分别检查3种热量条件时，当热量信息作为体力活动当量提供时，观察到显著效果（OR=0.51; 95%CI =0.31，0.85）。提供容易理解的热量信息，特别是身体活动当量，可以减少低收入黑人青少年从SSB摄入的热量。(Am J公共卫生。2012;102：329-335. doi：10.2105/AJPH.2011.300350）
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.
