The purpose of this study was to investigate the dietary habits and demand for nutrition service of university dormitory residents. Out of 450 questionnaires distributed to the undergraduate and graduate students residing in a university dormitory, 335(74.4%) returned and 265(58.8%) were analyzed. The analyzed sample included 140 males(52.8%) and 125 females(47.2%). The number of undergraduate and graduate students were 183(69.1%) and 82(30.9%), respectively. Male and undergraduate students tend to more frequently use dormitory foodservice than the respective counterpart. About 21% of respondents skipped breakfast everyday and almost 2/3 of respondents skipped breakfast more often than 3~4 times a week. The most often chosen reason for skipping meals was 'lack of time' for lunch and dinner as well as breakfast. Graduate students tend to drink coffee more often than undergraduate students. Male students were more likely to drink carbonated drinks and alcohol compared with female students. Over half(59%) of respondents were taking multivitamins and mineral supplements. About 80% of respondents perceived their health average or above. New residents having moved in to the dormitory less than a semester before tend to perceive their heath status worse than the residents having lived longer in the dormitory. The demand for nutrition service was high as shown by the high percentage of respondents willingness to receive the service: 76% for nutrition assessment service and 63% for nutrition counseling service. Such demand did not differ between males and female respondents. However, graduate students were more willing to participate in nutrition counseling service than undergraduates.
