OBJECTIVE
To evaluate the purchases of university vending machine clientele and to understand what consumers purchase, purchase motivations, and purchase frequency after implementation of a vending policy designed to promote access to healthier snack options.
METHODS
Cross-sectional data collection from consumers at 8 campus vending machines purposefully selected from a list of highest-grossing machines. Vending machines were stocked with 28.5% green (choose most often), 43% yellow (occasionally), and 28.5% red (least often) food items.
RESULTS
Consumers were predominately students (86%) and persons aged 18-24 years (71%). Red vending choices were overwhelmingly selected over healthier vending options (59%). Vended snack food selections were most influenced by hunger (42%) and convenience (41%). Most consumers (51%) frequented vending machines at least 1 time per week.
CONCLUSIONS AND IMPLICATIONS
Despite decreased access to less healthful red snack food choices, consumers chose these snacks more frequently than healthier options in campus vending machines.
目的
评估大学自动售货机顾客的购买情况，并了解在实施旨在促进提供更健康零食选择的自动售货政策后，消费者购买了什么、购买动机以及购买频率。
方法
从一份高销售额自动售货机列表中特意挑选出8台校园自动售货机，对消费者进行横断面数据收集。自动售货机中存放着28.5%的绿色（最常被选择）、43%的黄色（偶尔被选择）和28.5%的红色（最不常被选择）食品。
结果
消费者主要是学生（86%）和18至24岁的人群（71%）。与更健康的自动售货选择相比，红色自动售货选择被压倒性地选中（59%）。自动售货的零食选择受饥饿（42%）和便利性（41%）影响最大。大多数消费者（51%）每周至少光顾自动售货机1次。
结论与启示
尽管获取不太健康的红色零食选择的机会减少了，但在校园自动售货机中，消费者选择这些零食的频率高于更健康的选择。
