To measure children's consumption of, and liking for, fruit and vegetables and how these are altered by a peer modelling and rewards-based intervention.
In this initial evaluation of the programme, children's consumption of fruit and vegetables were compared within and across baseline and intervention phases.
Three primary schools in England and Wales.
In total, 402 children, aged from 4 to 11 y.
Over 16 days, children watched six video adventures featuring heroic peers (the Food Dudes) who enjoy eating fruit and vegetables, and received small rewards for eating these foods themselves.
Fruit and vegetable consumption was measured (i) in school at lunchtime and snacktime using a five-point observation scale, with inter-rated reliability and weighed validation tests; and (ii) at home using parental recall. A questionnaire measured children's liking for fruit and vegetables before and after the intervention.
Consumption during the intervention was significantly higher than during baseline at lunchtime and at snacktime (P<0.001 in all instances). Consumption outside school was significantly higher during the intervention on weekdays (P<0.05) but not weekend days. Following the intervention, children's liking for fruit and vegetables also showed a significant increase (P<0.001).
The peer modelling and rewards-based intervention was shown to be effective in bringing about substantial increases in children's consumption of, and expressed liking for, fruit and vegetables.

测量儿童对水果和蔬菜的摄入量及喜爱程度，以及基于同伴榜样和奖励的干预措施如何改变这些情况。
在该项目的初步评估中，比较了儿童在基线期和干预期内及不同阶段对水果和蔬菜的摄入量。
英格兰和威尔士的三所小学。
共有402名4至11岁的儿童。
在16天的时间里，儿童观看了六部视频短片，片中的英雄同伴（食物小英雄）喜欢吃水果和蔬菜，儿童自己食用这些食物可获得小奖励。
（i）在学校午餐时间和课间休息时，使用五点观察量表测量水果和蔬菜的摄入量，并进行评分者间信度和加权效度测试；（ii）在家中通过家长回忆来测量。通过问卷调查测量干预前后儿童对水果和蔬菜的喜爱程度。
干预期间午餐时间和课间休息时的摄入量显著高于基线期（所有情况下P<0.001）。在工作日干预期间校外摄入量显著更高（P<0.05），但周末没有差异。干预后，儿童对水果和蔬菜的喜爱程度也显著增加（P<0.001）。
基于同伴榜样和奖励的干预措施被证明能有效大幅增加儿童对水果和蔬菜的摄入量及喜爱程度。
