To determine the effects of a nutrition information intervention on the vending machine purchases on a college campus.
Five high-use vending machines were selected for the intervention, which was conducted in the fall of 2011. Baseline sales data were collected in the 5 machines prior to the intervention. At the time of the intervention, color-coded stickers were placed near each item selection to identify less healthy (red), moderately healthy (yellow), and more healthy (green) snack items. Sales data were collected during the 2-week intervention.
Purchases of red- and yellow-stickered foods were reduced in most of the machines; moreover, sales of the green-stickered items increased in all of the machines.
The increased purchases of healthier snack options demonstrate encouraging patterns that support more nutritious and healthy alternatives in vending machines.
确定营养信息干预对大学校园自动售货机购买行为的影响。
选择五台高使用率的自动售货机进行干预，干预于2011年秋季进行。在干预前收集这五台机器的基线销售数据。干预时，在每个商品选择处附近贴上颜色编码贴纸，以识别不太健康（红色）、中度健康（黄色）和更健康（绿色）的零食。在为期两周的干预期间收集销售数据。
大多数机器中红色和黄色贴纸食品的购买量减少；此外，所有机器中绿色贴纸商品的销售量增加。
更健康零食选择购买量的增加显示出令人鼓舞的模式，支持自动售货机提供更营养、更健康的选择。
