In light of the childhood obesity epidemic, many cities are adopting healthy park vending policies, but the evidence on the effectiveness of these policies is scant. This study examines how implementation of a healthy vending policy in Carson, California, changes the types of beverages that are available in park vending machines. The study design is a pre-posttest with post-only comparison group. The main outcome is proportion of beverages in vending machines that is consistent with caloric and sugar content guidelines for children as defined by the Nutrition Environment Measures-Vending (NEMS-V) tool. This study finds that prior to implementation of the vending policy, 70% of the beverages did not meet NEMS-V guidelines, on average. After implementation of the vending policy, this number declined to 7%. This study suggests that healthy vending policies can have an impact on the types of beverages that are available in city parks.
鉴于儿童肥胖问题的流行，许多城市正在采用健康的公园自动售货政策，但关于这些政策有效性的证据却很少。本研究考察了加利福尼亚州卡森市一项健康自动售货政策的实施如何改变公园自动售货机中可供选择的饮料类型。研究设计为前后测且仅设后测对照组。主要结果是自动售货机中符合营养环境测量-自动售货（NEMS-V）工具所定义的儿童热量和糖分含量指南的饮料比例。本研究发现，在自动售货政策实施之前，平均70%的饮料不符合NEMS-V指南。自动售货政策实施后，这一数字降至7%。本研究表明，健康自动售货政策会对城市公园中可供选择的饮料类型产生影响。
