背景：在最近的一项研究中，我们表明非食物激励措施与味觉接触相结合可以增加儿童对蔬菜的接受度。然而，儿童以前接受食物奖励的经验的影响是未知的。本研究调查了食物奖励的体验是否会影响对暴露加奖励干预的反应。方法：137名4-6岁儿童的父母参加了一项基于暴露的干预研究，完成了一项工具性喂养（IF）问卷，旨在评估他们对食物奖励的使用。根据这些分数，儿童被归类为经常或很少工具喂养。干预组每天品尝12种目标蔬菜，没有奖励，有形奖励（贴纸）或口头奖励（赞美）。未处理对照组不接受品尝。在基线和干预后测量目标蔬菜的喜欢和摄入量。结果：不考虑IF的经验，与对照组相比，所有干预组的儿童都增加了喜欢（P < 0.001），两个奖励组与对照组相比，摄入量增加（P < 0.05）。然而，在非奖励暴露组中，只有有限的食物奖励经验的儿童增加了消费（P < 0.05）。结论：IF的经验可能会限制“纯粹的奖励”的好处。然而，接触非食物奖励可以增加蔬菜的接受程度，无论以前的经验如何。
Background: In a recent study, we showed that nonfood incentives combined with taste exposure increase children's acceptance of vegetables. However, the impact of children's previous experience of receiving food rewards is unknown. The present study investigated whether the experience of food rewards affects responses to an exposure-plus-reward intervention.Methods: One hundred and thirty-seven parents of 4-6-year-old children taking part in an exposure-based intervention study completed an instrumental feeding (IF) questionnaire aiming to assess their use of food rewards. Based on these scores, children were categorised as frequently or rarely instrumentally-fed. Intervention groups were given 12 daily tastes of a target vegetable combined with no reward, a tangible reward, (sticker) or a verbal reward (praise). A no-treatment control group received no tastings. Liking and intake of a target vegetable were measured at baseline and post-intervention.Results: Irrespective of experience of IF, children in all intervention groups increased liking compared to controls (all P < 0.001) and both reward groups increased intake compared to controls (both P < 0.05). However, in the nonrewarded exposure group, only children with a limited experience with food rewards increased consumption (P < 0.05).Conclusions: Experience of IF may limit the benefits of 'mere exposure'. However, exposure with nonfood rewards can increase the acceptance of vegetables, regardless of previous experience.
