Improving children's fruit and vegetable (FV) preferences may be important as preferences can predict FV consumption. The purpose of this study was to evaluate FV preferences over time, with repeated experience, as part of the Fresh Fruit and Vegetable Program (FFVP).
Fruits (F; N = 28) and vegetables (V; N = 29) were distributed twice a week, over 35 weeks, at a participating FFVP school (N = 236 students, 12 teachers, K-2nd grade). Preference ratings using 3-point Likert scale were analyzed over 35 weeks.
For 57 FVs rated for preference, ratings revealed that F had higher frequency of children choosing "I like it" than for V (78% F; 38.2% V; p < .05) and liking distribution was different between F and V (p < .001). Significant relations were found between liking and: (1) grade (r = -0.02, p = .02), and (2) time (r = -0.09, p < .001). Models indicated that V served (β = -0.40), timepoint (β = -0.07), and grade level (β = -0.02) accounted for significant variance for preference ratings (R = 0.17, p < .001), indicating that preference ratings declined over time.
Fruits were preferred over vegetables. Overall preference ratings were negatively impacted by time, grade level, and vegetables served. Being exposed one time to a variety of FVs did not improve ratings for vegetables.
改善儿童对水果和蔬菜（FV）的偏好可能很重要，因为偏好可以预测 FV 的消费。本研究的目的是评估随着时间的推移，通过反复体验，作为新鲜水果和蔬菜计划（FFVP）的一部分，FV 偏好的变化。
在参与 FFVP 的学校中，每周两次分发水果（F；N=28）和蔬菜（V；N=29），共 35 周（N=236 名学生，12 名教师，K-2 年级）。使用 3 点李克特量表分析了 35 周的偏好评分。
对于 57 种被评估为偏好的 FV，评分显示 F 组中选择“我喜欢”的孩子比例高于 V 组（78% F；38.2% V；p<.05），且 F 和 V 之间的喜好分布不同（p<.001）。发现喜好与以下因素之间存在显著关系：（1）年级（r=-0.02，p=.02），和（2）时间（r=-0.09，p<.001）。模型表明，V 的供应（β=-0.40）、时间点（β=-0.07）和年级水平（β=-0.02）解释了偏好评分的显著差异（R2=0.17，p<.001），表明随着时间的推移，偏好评分下降。
水果比蔬菜更受欢迎。总体偏好评分受到时间、年级水平和供应的蔬菜的负面影响。一次接触多种 FV 并不能提高对蔬菜的评分。
