    Abstract:
    PURPOSE: The Healthy Vending Machine Pilot Project (HVMPP) was a public health initiative intended to create a healthier school nutrition environment by making healthier snacks available in vending machines, while maintaining a profit margin. The HVMPP was evaluated using quantitative and qualitative measures. METHODS: Vending machines were stocked with healthier choices and conventional vending products at a 50:50 ratio. The HVMPP was implemented from February to May 2007 in four Ontario secondary schools in Middlesex-London, Elgin, and Oxford counties. Product sales were tracked, and focus groups were conducted to obtain students' opinions about healthy eating and vending choices. RESULTS: "Healthier choice" sales ranged from 14% to 17%. In all schools, vending revenues declined from 0.7% to 66%. A majority of participants had substantial knowledge of healthy eating and were in favour of healthier choices in vending machines; however, price, value, and taste were barriers that led them to purchase these products rarely. Students preferred to have "real" healthy snacks, such as yogurt, fruit, and vegetables, available in schools. CONCLUSIONS: Replacing 50% of vending stock with healthier snacks resulted in a decline in vending revenues. Future health programs in schools need to provide "real" healthy snacks, such as low-fat dairy products, fruits, and vegetables.
