“…The types of intervention strategies included promotion of healthier food and drink choices (n = 11, 85%) [13,14,[17][18][19][20][21][22][23][24][25], increasing the availability of healthier food and drinks within vending machines (n = 8, 62%) [13,14,[22][23][24][25][26][27], price alterations (n = 4, 31%) [13,14,20,24], and modifying product placement within vending machines (n = 2, 15%) [14,23]. Interventions in seven studies involved more than one of these strategies, with three studies using two strategies [20,22,25], three studies using three strategies [13,23,24], and one study using four strategies [14]. The most common combinations of strategies were increasing the availability and promotion of healthier food and/or drink choices [22,25] and increasing the availability and promotion of healthier food and/or drink choices and price alterations [13,24], used in two studies each.…”

“…The most common combinations of strategies were increasing the availability and promotion of healthier food and/or drink choices [22,25] and increasing the availability and promotion of healthier food and/or drink choices and price alterations [13,24], used in two studies each. The outcome measures included purchases/sales from vending machines in all except one study (n = 12, 92%) [13,14,[17][18][19][20][21][22][23][24][25][26]28] (Table 2). Two studies (15%) also measured the acceptability of/satisfaction with the intervention [22,26], and one study (8%) also measured dietary behavior change [22].…”

“…In seven studies (3 RCTs, 3 pre-post tests, 1 non-randomized controlled trial), interventions involved a combination of two or more strategies [13,14,20,[22][23][24][25]. Of these, four studies (57%) reported positive change in outcomes [13,14,20,23].…”

“…One study, the non-randomized controlled trial by Viana et al, involved all four strategies, (increasing the availability and promotion of healthier food and/or drink choices, modifying product placement, and price alterations). In this study, healthier items were made more available (minimum 25% of options), optimally placed within vending machines (grouped together including dedicated rows placed at eye level) and promoted via 'Eat Well' stickers, while the price of candy bars was increased by 25% [14]. During the two-month intervention, the proportion of healthier items sold was 21.3% in intervention compared with 1.3% in control machines (i.e., a difference of 20.0%) with no significant difference in revenue.…”

“…Of the 12 included studies, eight reported significant findings following intervention, with the most effective strategies being price reductions and increasing the availability of healthier items, resulting in increases in sales for healthier items. As four years has elapsed since this review was conducted and relevant studies in the university setting have since been published [13,14], an updated review of the evidence is warranted.…”

Effectiveness of Nutrition Interventions in Vending Machines to Encourage the Purchase and Consumption of Healthier Food and Drinks in the University Setting: A Systematic Review

2020

University food environments typically offer an abundance of unhealthy foods, including through vending machines. This review evaluated the effectiveness of nutrition interventions in vending machines in the university setting. Ten databases were searched for experimental studies published up to July 2019, evaluating nutrition interventions that aimed to encourage the purchase or consumption of healthier foods and drinks in vending machines in the university setting. In total, 401 articles were identified, and 13 studies were included. Studies were pre-post test (n = 7, 54%), randomized controlled trials (RCTs) (n = 5, 38%), and non-randomized controlled trial (n = 1, 8%). Most studies were from the USA (n = 10, 77%) and were published between 2014 and 2018 (n = 9, 69%). Eight interventions (62%) reported positive change in outcomes, including increased number/proportion of sales or revenue from healthier items (n = 6), improved adherence to guidelines for the ratio of healthy/unhealthy products available (n = 1), and improved consumer perception of items available (n = 1). Effective interventions involved the promotion, reduced pricing, increased availability, and/or optimized product placement of healthier items within vending machines. Strategies to improve the nutritional quality of food and drinks in vending machines are warranted. This may be achieved by making healthier options more available and promoting them; however, more robust intervention studies are needed to determine effectiveness.

Vending Machines in Australian Hospitals: Are They Meeting the Needs of the Consumer?

The current report explores how well vending machines are meeting the needs of health care organizations and their staff and visitors in Australia. Hospital vending machines often provide the only source of food through the night to staff and visitors and traditionally offer less-healthy options. Findings presented in this report suggest that vending machines are not meeting current statewide policies and guidelines for healthier food environments in health care. This is despite widespread support for healthier refreshments in hospitals by staff, visitors, and patients. Alternatives to traditional vending and opportunities for nutrition educators and researchers are discussed.

University nutrition policies are a useful step toward improving the food environment for students, faculty, and staff, leading to improved health outcomes for the campus community. As 1 of the first universities to adopt and implement a campus-wide nutrition policy, the objective of this report is to share the university's experience with policy development, implementation, monitoring and evaluation, challenges, facilitators, and recommendations to inform these processes for future university nutrition policies.
