有关使用营养标签的个人特征以及标签使用对饮食质量影响的信息可用于指导制定更有效的消费者教育计划。本研究使用美国农业部 (USDA) 1989 年个人食物摄入量持续调查 (CSFII) 和饮食与健康知识调查 (DHKS) 的数据来确定社会经济、人口和健康相关特征以及与标签使用相关的营养相关知识和态度。该分析采用了基于信息搜索经济模型的标签使用决定因素的理论模型。与使用营养标签的可能性呈正相关的特征包括至少接受过一些大学教育、女性、与他人一起生活而不是独居、对营养有更多了解、相信遵循《美国人膳食指南》的原则很重要、在购买食品时更关心营养和产品安全而不是口味。在确定了标签使用者的特征后，该信息被用于基于消费者需求理论的营养消耗模型中。采用选择性分析来纠正标签使用上潜在的自我选择偏差。标签的使用似乎与摄入维生素 C 含量较高和胆固醇含量较低的饮食有关。然而，1989 年的标签使用并未显着影响所调查的 24 种其他食品成分的摄入量。
Information on the characteristics of individuals using nutrition labeling and the effects of label use on diet quality can be used to guide the development of more effective consumer education programs. For this study, data from the U.S. Department of Agriculture's (USDA) 1989 Continuing Survey of Food Intakes by Individuals (CSFII) and Diet and Health Knowledge Survey (DHKS) were used to identify socioeconomic, demographic, and health-related characteristics and the nutrition-related knowledge and attitudes that were associated with label use. This analysis employed a theoretical model of determinants of label use that was based on an economic model of information search. Characteristics found to be positively associated with the likelihood of using nutrition labeling were having at least some college education, being female, living with others rather than living alone, being more knowledgeable about nutrition, believing that following the principles of the Dietary Guidelines for Americans is important, and being more concerned about nutrition and product safety and less about taste when shopping for food. Having identified the characteristics of label users, this information was used in a model of nutrient consumption that was based on consumer demand theory. A selectivity analysis was employed to correct for potential self-selection bias on label use. Label use appeared to be associated with the consumption of diets that were higher in vitamin C and lower in cholesterol. However, label use in 1989 did not significantly influence the intake of 24 other food components investigated.
