Consumer Awareness and Preferences Related to Taurine-Containing Drinks in Korean Female High School Students.

Abstract

The purpose of this cross-sectional study was to investigate awareness, consumption patterns, and preferences related to intake experience of taurine-containing drinks (TCD) in Korean female high school students. Study subjects were 335 female high school students residing in Incheon, Korea. Data were collected using self-administered questionnaires. A total of 249 students (74.3%) consumed TCD while 86 students (25.7%) did not. In the TCD consumption group, 66.7% of consumers drank TCD once every 2 or 3 months while most consumers consumed it during the examination period (57.4%). Regarding the effects of TCD intake, 45.8% of students cited 'relieve sleepiness' while 41.8% showed 'no effect'. According to self-reported school records, there were significant differences in intake time of TCD, effects of TCD intake, and degree of interest in TCD (p < 0.05). About 82.7% of all the subjects perceived TCD as an energy drink for fatigue recovery. Degree of interest in TCD (p < 0.001), degree of harmfulness to the body (p < 0.01), and improvement for learning-ability (p < 0.001) had significant effects on intake frequency of TCD. Regarding preferences, 'Vita 500' was preferred by 52.2% of subjects, 'Bacchas' by 20.1%, and 'Hot Six' by 17.3%. Although subjects preferred 'Vita 500' as a caffeine-free TCD, caffeine was perceived as the most abundant ingredients in TCD by 77.1% of subjects, taurine by 16.1%, and vitamin by 4.8%. These results show most Korean female high school students consumed TCD in order to stay awake during the examination periods. Therefore, nutritional education is needed to correct Korean high school students' consumption of TCD.
