용인지역 고등학생의 카페인 섭취수준에 따른 카페인에 대한 인식도, 지식도 및 구매행동

Abstract

This study examined the awareness, knowledge, and purchasing behavior of caffeine according to the caffeine intake level (〈30 mg, 30∼60 mg, 60∼90 mg, and 〉90 mg) of high school students (171 males and 139 females) in the Yongin region. The awareness of low doses of caffeine was higher in the 〈30 mg group (70.7%) and awareness of high doses of caffeine was higher in the 〉90 mg group (30.0%) (p〈0.001). Withdrawal symptoms included ‘sleep disorder’ in all groups and ‘fatigue’ was higher in the 〉90 mg group (30.0%) compared to the other groups (p〈0.01). The knowledge score of ‘coffees’ and ‘energy drinks’ was higher, whereas ‘chocolate ice cream’, ‘carbonated soft drinks’, and ‘confectionaries with chocolate’ was lower regardless of the caffeine intake level (p〉0.05). The main purpose of purchasing ‘energy drinks’ was ‘sleepy’ except for the 30∼60 mg group (p〈0.05). The percentage of those checking the food labelling related to caffeine when buying caffeinated foods was low in all groups (〈30 mg, 13.0%; 30∼60 mg, 13.5%; 60∼90 mg, 15.0%; 〉90 mg, 26.7%) (p〉0.05). The results of factors affecting whether the students checked the food labelling related to caffeine showed that the participants having awareness of ‘don’t know caffeinated foods’ checked the labels 6.50 times more than those reporting ‘know caffeinated foods’ (p〈0.05). In conclusion, the degree of knowledge and checking food labelling for caffeine was low regardless of the caffeine intake level. Therefore, providing better nutrition education programs on the functionality and adverse effects of caffeine to high school students is recommended.
