BACKGROUND/OBJECTIVES: Use of nutrition labels in food selection is recommended for consumers. The aim of this studyis to examine factors, mainly beliefs explaining nutrition label use in female college students based on the Theory of PlannedBehavior (TPB). SUBJECTS/METHODS: The subjects were female college students from a university in Seoul, Korea. The survey questionnairewas composed of items examining general characteristics, nutrition label use, behavioral beliefs, normative beliefs, correspondingmotivation to comply, and control beliefs. The subjects (n = 300) responded to the questionnaire by self-report, and data from275 students were analyzed using t-test or χ2-test. RESULTS: The results showed that 37.8% of subjects were nutrition label users. Three out of 15 behavioral beliefs differedsignificantly by nutrition label use. Nutrition label users agreed more strongly on the benefits of using nutrition labels including‘comparing and selecting better foods’ (P < 0.001), ‘selecting healthy foods’ (P < 0.05). The negative belief of ‘annoying’ wasstronger in non-users than in users (P < 0.001). Three out of 7 sources (parents, siblings, best friend) were important in nutritionlabel use. Twelve out of 15 control beliefs differed significantly by nutrition label use. These included beliefs regarding constraintsof using nutrition labels (e.g., time, spending money for healthy foods) and lack of nutrition knowledge (P < 0.001). Perceivedconfidence in understanding and applying the specifics of nutrition labels in food selection was also significantly related tonutrition label use (P < 0.001). CONCLUSIONS: This study found that the beliefs, especially control beliefs, suggested in the TPB were important in explainingnutrition label use. To promote nutrition label use, nutrition education might focus on increasing perceived control over constraintsof using nutrition labels, acquiring skills for checking nutrition labels, as well as the benefits of using nutrition labels andreceiving support from significant others for nutrition label use.
