Children do not eat enough servings of vegetables, underscoring the need for effective interventions encouraging this behavior. The purpose of this research was to measure the impact that daily exposure to branded vegetable characters has on vegetable selection among boys and girls in elementary schools.
In a large urban school district, 10 elementary schools agreed to participate in the study. They were randomly assigned to a control condition or 1 of 3 treatment conditions: (1) a vinyl banner displaying vegetable characters that was fastened around the base of the salad bar; (2) short television segments with health education delivered by vegetable characters; or (3) a combination of the vinyl banner and television segments. We collected 22 206 student-day observations over a 6-week period by tallying the number of boys and girls taking vegetables from the school's salad bar.
Results show that 90.5% (from 12.6% to 24.0%; P = .04) more students took vegetables from the salad bar when exposed to the vinyl banner only, and 239.2% (from 10.2% to 34.6%; P < .001) more students visited the salad bar when exposed to both the television segments and vinyl banners. Both boys and girls responded positively to the vinyl banners (P < .05 in both cases).
Evidence from this study highlights the positive impact of branded media on children's vegetable selection in the school cafeteria. Results from this study suggest potential opportunities for using branded media to encourage healthier choices for children.
儿童摄入的蔬菜份数不足，这凸显了采取有效干预措施来鼓励这种行为的必要性。本研究的目的是衡量每天接触品牌蔬菜角色对小学男生和女生蔬菜选择的影响。
在一个大型城市学区，10所小学同意参与该研究。它们被随机分配到一个对照条件或3种处理条件中的1种：（1）一个展示蔬菜角色的乙烯基横幅，固定在沙拉吧的底部；（2）由蔬菜角色进行健康教育的简短电视片段；或（3）乙烯基横幅和电视片段的组合。我们在6周的时间里通过统计从学校沙拉吧取用蔬菜的男生和女生人数，收集了22206个学生日观察数据。
结果显示，仅接触乙烯基横幅时，从沙拉吧取用蔬菜的学生增加了90.5%（从12.6%增至24.0%；P = .04），同时接触电视片段和乙烯基横幅时，光顾沙拉吧的学生增加了239.2%（从10.2%增至34.6%；P < .001）。男生和女生对乙烯基横幅均有积极反应（两种情况P均 < .05）。
本研究的证据突出了品牌媒体对学校食堂中儿童蔬菜选择的积极影响。本研究结果表明了利用品牌媒体鼓励儿童做出更健康选择的潜在机会。
