目标.本研究探讨了价格对从自动售货机购买低脂零食的作用。在为期4周的基线、为期3周的干预（其中低脂零食价格降低50%）和干预后3周，在9台自动售货机中监测低脂和常规零食的销售情况。三个时期购买低脂零食的比例分别为25.7%、45.8%和22.8%。零食购买总量没有因时期而变化。结论。降低相对价格可能有效地促进人们选择低脂肪食物。自动售货机可能是实施这种营养干预措施的可行方法。
Objectives. This study examined the role of price on purchases of low-fat snacks from vending machines.Methods. Sales of low-fat and regular snacks were monitored in nine vending machines during a 4-week baseline, a 3-week intervention in which prices of low-fat snacks were reduced 50%, and 3 weeks postintervention.Results. The proportion of low-fat snacks-purchased was 25.7%, 45.8%, and 22.8% in the three periods, respectively. Total snack purchases did not vary by period.Conclusions. Reducing relative prices may be effective in promoting lower-fat food choices in the population. Vending machines may be a feasible method for implementing such nutrition interventions.
