This study examined the influence of 1990 Nutrition Labeling and Education Act food labels on college students. The purposes of the study were to examine knowledge, attitudes, and behaviors of college students regarding labels and relationships among these factors, and whether educational experience with labels was associated with label-reading knowledge, attitudes, and behaviors.
A descriptive, nonexperimental research design was used. Data were gathered using a survey designed for the study.
The study surveyed 208 undergraduate students enrolled in general education classes at a midwestern university.
Descriptive statistics analyzed knowledge, attitudes, and behaviors of college students regarding food labels. The Student t test and chi 2 analysis evaluated specific measures of behavior. Pearson correlation coefficients and multiple regression analysis examined relationships among variables and identified factors associated with label use.
Students' mean knowledge score was 48%. Knowledge score was positively correlated with attitudes toward labels (r = .14, P = .04) and use of labels (r = .87, P = .0001). Previous education in reading labels was associated with higher knowledge scores (P = .04). Ninety-five percent of participants perceived the label to be useful, but many distrusted nutrition claims. Seventy percent looked at the Nutrition Facts label when purchasing a product for the first time. The single best predictor of general label use was a positive attitude toward labels (P < .001), followed by being a woman (P < .01).
The 1990 National Labeling and Education Act food label has influenced college students. Labeling education efforts are associated with greater knowledge about labels, more favorable attitudes toward them, and increased label use in making food choices. Special attention should be directed toward explaining terms and phrases on labels and the guidelines that ensure truthfulness of nutrition claims. College students need to understand their need for numerous nutrients instead of merely focusing on the fat and caloric content of foods.
本研究调查了1990年《营养标签与教育法》食品标签对大学生的影响。该研究的目的是考察大学生关于标签的知识、态度和行为,以及这些因素之间的关系,还有标签教育经历是否与标签阅读知识、态度和行为相关。
采用描述性非实验研究设计。通过为该研究设计的一项调查收集数据。
该研究对一所中西部大学参加通识教育课程的208名本科生进行了调查。
描述性统计分析了大学生关于食品标签的知识、态度和行为。学生t检验和卡方分析评估了特定的行为指标。皮尔逊相关系数和多元回归分析考察了变量之间的关系,并确定了与标签使用相关的因素。
学生的平均知识得分是48%。知识得分与对标签的态度呈正相关(r = 0.14,P = 0.04)以及与标签的使用呈正相关(r = 0.87,P = 0.0001)。之前的标签阅读教育与更高的知识得分相关(P = 0.04)。95%的参与者认为标签有用,但许多人不信任营养声明。70%的人在首次购买产品时会查看营养成分标签。对标签总体使用的唯一最佳预测因素是对标签的积极态度(P < 0.001),其次是女性(P < 0.01)。
1990年《国家标签与教育法》食品标签对大学生产生了影响。标签教育努力与对标签有更多了解、对其有更积极的态度以及在做出食物选择时增加标签使用相关。应特别关注解释标签上的术语和短语以及确保营养声明真实性的指南。大学生需要了解他们对多种营养素的需求,而不仅仅是关注食物的脂肪和热量含量。
