背景。这项研究探讨了这样一个假设：如果增加产品种类并降低价格，自助餐厅的水果和沙拉消费量将会增加。方法。在 3 周的基线观察、3 周的干预和 3 周恢复到基线条件期间，对自助餐厅的食品购买情况进行了观察。干预措施包括将水果选择数量增加一倍，将沙拉配料选择增加三种，并将水果和沙拉的价格降低 50%。该研究的主要结果指标是根据收银机收据评估的水果和沙拉的每日销量。结果。与非干预期相比，干预期的水果和沙拉购买量增加了三倍。女性和那些试图控制体重的人最有可能选择这些营养食品。结论。这项研究的结果支持这样的论点：增加营养食品选择的数量并使其在经济上更具吸引力可能对改变食物选择行为很重要。建议进一步探索该概念的实际应用。 (C) 1994 年学术出版社
Background. This study explored the hypothesis that consumption of fruit and salad in a cafeteria setting would increase if the variety of offerings was increased and their price reduced.Method. Food purchases in a cafeteria setting were observed during 3 weeks of baseline observation, 3 weeks of intervention, and 3 weeks of return to baseline conditions. Intervention consisted of doubling the number of fruit choices, increasing salad ingredient selections by three, and reducing the price of both fruit and salad by 50%. The primary outcome measures in the study were daily sales of fruit and salad as assessed by cash register receipts.Results. Fruit and salad purchases increased threefold in the intervention period compared to those in the nonintervention periods. Women and those trying to control their weight were most likely to make these nutritious food choices.Conclusion. Results of this study support the argument that increasing the number of nutritious food choices and making them more attractive economically may be important to changing food choice behavior. Further exploration of the practical application of the concept is recommended. (C) 1994 academic Press, Inc.
