Abstract

Objectives

To place Smart Snacks in vending machines and determine if different sales strategies affect Smart Snack selection.

Participants

University students living in resident halls

Methods

Vending machines included 50% Smart Snacks and 50% non compliant snacks. Three sales strategies targeted student selection of Smart Snacks: Reduced price, signage, and nutrition education activities. Three-way ANOVA was used for analysis.

Results

There was a statistically significant three-way interaction on snack selection between sales strategy, study period, and snack type, F(4, 77) = 3.33, P = .01. There were no statistically significant simple two-way interaction between study period and sales strategy for either Smart Snack, F(1, 77) = 1.62, P = 0.18, or NC snack types, F(1, 77) = 2.02, P = 0.07.

Conclusions

Sales strategies did not affect Smart Snack selections. Advocates for healthier snacks in vending machines can align with university administrations to establish nutrient guidelines.

智能零食干预对大学生售卖选择的影​​响

摘要

目标

将Smart Snack放入自动售货机并确定不同的销售策略是否会影响Smart Snack 的选择。

参加者

住在学生宿舍的大学生

方法

自动售货机包括 50% 的智能零食和 50% 的不合规零食。三种针对学生选择的Smart Snacks的销售策略：降价、标牌和营养教育活动。三向方差分析用于分析。

结果

在销售策略、研究期间和零食类型之间，零食选择存在统计学上显着的三向交互作用，F (4, 77) = 3.33，P = .01。对于Smart Snack，F (1, 77) = 1.62，P  = 0.18，或 NC 零食类型，F (1, 77) = 2.02，P  = 0.07。

结论

销售策略不会影响Smart Snack 的选择。在自动售货机中提倡更健康的零食可以与大学管理部门合作制定营养指南。
