To determine whether food label information and advertisements for foods containing no fruit cause children to have a false impression of the foods' fruit content.
In the food label condition, a trained researcher showed each child sixteen different food label photographs depicting front-of-food label packages that varied with regard to fruit content (i.e. real fruit v. sham fruit) and label elements. In the food advertisement condition, children viewed sixteen, 30 s television food advertisements with similar fruit content and label elements as in the food label condition. After viewing each food label and advertisement, children responded to the question 'Did they use fruit to make this?' with responses of yes, no or don't know.
Schools, day-care centres, after-school programmes and other community groups.
Children aged 4-7 years.
In the food label condition, χ 2 analysis of within fruit content variation differences indicated children (n 58; mean age 4·2 years) were significantly more accurate in identifying real fruit foods as the label's informational load increased and were least accurate when neither a fruit name nor an image was on the label. Children (n 49; mean age 5·4 years) in the food advertisement condition were more likely to identify real fruit foods when advertisements had fruit images compared with when no image was included, while fruit images in advertisements for sham fruit foods significantly reduced accuracy of responses.
Findings suggest that labels and advertisements for sham fruit foods mislead children with regard to the food's real fruit content.
确定不含水果的食品标签信息和广告是否会使儿童对这些食品的水果含量产生错误认知。
在食品标签条件下,一名经过培训的研究人员向每个儿童展示16张不同的食品标签照片,这些照片描绘了食品标签正面包装,其水果含量(即真水果与假水果)和标签元素各不相同。在食品广告条件下,儿童观看16个30秒的电视食品广告,其水果含量和标签元素与食品标签条件下的类似。在观看每个食品标签和广告后,儿童回答“他们用水果制作这个吗?”这个问题,回答为是、否或不知道。
学校、日托中心、课后活动项目及其他社区团体。
4至7岁的儿童。
在食品标签条件下,对水果含量变化差异进行的χ²分析表明,随着标签信息负载量的增加,儿童(n = 58;平均年龄4.2岁)在识别真水果食品时的准确率显著提高,而当标签上既没有水果名称也没有图像时,准确率最低。在食品广告条件下,与没有图像的广告相比,当广告中有水果图像时,儿童(n = 49;平均年龄5.4岁)更有可能识别出真水果食品,而假水果食品广告中的水果图像显著降低了回答的准确率。
研究结果表明,假水果食品的标签和广告在食品的真实水果含量方面误导了儿童。
