Abstract

While much research has focused on intake and eating behaviors of young adolescents, few studies have examined their knowledge of the Nutrition Facts label. The goals of this project were to assess the understanding of Nutrition Facts labels and the response of young adolescents to an educational program about Nutrition Facts labels. Thirty-four young adolescents participated by answering a short questionnaire and taking a pretest about Nutrition Facts labels and their food choices, which involved using actual Nutrition Facts labels from foods typically eaten by adolescents. Then the subjects participated in a short educational program on how to read the Nutrition Facts label. This was followed by a posttest. Initial knowledge of the basic use of the Nutrition Facts label was marginal, with only 6.65 (standard deviation=2.23) or approximately 55% of pretest questions answered correctly. However, the subjects' scores improved significantly to 8.32 (standard deviation=2.01) or approximately 70% correct on the posttest (P<0.0001, Fisher's exact test) after the educational session. In conclusion, young adolescents can learn how to read and understand the Nutrition Facts labels through educational sessions.

摘要

虽然许多研究都集中在青少年的摄入量和饮食行为上，但很少有研究考察他们对营养成分标签的了解。本项目的目标是评估青少年对营养成分标签的理解，以及他们对关于营养成分标签的教育项目的反应。34名青少年参与了该项目，他们回答了一份简短的问卷，并参加了一项关于营养成分标签及其食物选择的预测试，其中涉及使用青少年通常食用的食物的实际营养成分标签。然后，受试者参加了一个关于如何阅读营养成分标签的简短教育项目。随后进行了后测。对营养成分标签基本用途的初始了解程度一般，预测试题中只有6.65分（标准差=2.23），即约55%的问题回答正确。然而，在教育课程结束后的后测中，受试者的分数显著提高到8.32分（标准差=2.01），即约70%的问题回答正确（P<0.0001，费舍尔精确检验）。总之，青少年可以通过教育课程学习如何阅读和理解营养成分标签。
