To develop healthier vending guidelines and assess their effect on the nutrient content and sales of snack products sold through hospital vending machines, and on staff satisfaction.
Nutrition guidelines for healthier vending machine products were developed and implemented in 14 snack vending machines at two hospital sites in Auckland, New Zealand. The guidelines comprised threshold criteria for energy, saturated fat, sugar, and sodium content of vended foods. Sales data were collected prior to introduction of the guidelines (March-May 2007), and again post-introduction (March-May 2008). A food composition database was used to assess impact of the intervention on nutrient content of purchases. A staff survey was also conducted pre- and post-intervention to assess acceptability.
Pre-intervention, 16% of staff used vending machines once a week or more, with little change post-intervention (15%). The guidelines resulted in a substantial reduction in the amount of energy (-24%), total fat (-32%), saturated fat (-41%), and total sugars (-30%) per 100 g product sold. Sales volumes were not affected, and the proportion of staff satisfied with vending machine products increased.
Implementation of nutrition guidelines in hospital vending machines led to substantial improvements in nutrient content of vending products sold. Wider implementation of these guidelines is recommended.
制定更健康的自动售货指南，并评估其对通过医院自动售货机销售的零食产品的营养成分、销售量以及员工满意度的影响。
针对更健康的自动售货机产品制定营养指南，并在新西兰奥克兰的两个医院地点的14台零食自动售货机上实施。这些指南包括自动售货食品的能量、饱和脂肪、糖和钠含量的阈值标准。在指南引入之前（2007年3月至5月）以及引入之后（2008年3月至5月）收集销售数据。使用食物成分数据库评估干预措施对购买产品营养成分的影响。在干预前后还进行了员工调查以评估可接受性。
干预前，16%的员工每周使用自动售货机一次或更多次，干预后变化不大（15%）。这些指南使每100克售出产品的能量（-24%）、总脂肪（-32%）、饱和脂肪（-41%）和总糖（-30%）含量大幅降低。销售量未受影响，对自动售货机产品满意的员工比例有所增加。
在医院自动售货机中实施营养指南使所售自动售货产品的营养成分有了显著改善。建议更广泛地实施这些指南。
