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.
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.
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.
Despite decreased access to less healthful red snack food choices, consumers chose these snacks more frequently than healthier options in campus vending machines.
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。
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。
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。
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。
