The purpose of this study was to investigate the dietary behavior and late-night eating habit of university students in Daejeon. Questionnaires were collected from 432 students and statistically analyzed according to residence type. One thirds of students took meals irregularly and skipped breakfast because of no time. Both Relative self-boarding and dormitory boarding group skipped breakfast more frequently than home group(p<0.01). The carbonated drink was most frequently chosen during late-night eating. The most favorite alcoholic beverage was soju and 54.7% of students drank soju 1~2 times per week near campus. Almost half of them took late-night foods 1~2 times per week at home(51.8%), near campus(25.8%), near home(15.6%), down town(6.9%). The percentage of late-night eating near campus was higher in dormitory boarding group than both home group and relative self-boarding group(p<0.001). Late-night foods were selected based on taste in 1~2 man won and enjoyed with 2~3 friends until 12 pm. The more in relative self-boarding group chose late-night foods based on taste than both home and dormitory boarding group(p<0.05). The main intake method for late-night foods was delivery. The results of this study suggest that nutritional education is required for relative self-boarding group to change dietary behavior and to select proper late-night foods for their health.
