This study was performed to investigate dietary habits and nutrient intakes of college students in Gyeonggi-do area. Survey questionnaire and daily intake using 24-hour recall method were recorded by 351 college students (172 males, 179 females) . Nutrient intakes were calculated using Can-pro 2.0, from which $\%$RDA (Recommended dietary allowances), NAR (Nutrient adequacy ratio), MAR (Mean nutrient adequacy ratio), and ND (Nutrient density) were calculated to evaluate the quality of diets. Subjects answered 9 questions on dietary habits and these answers were calculated as 0, 0.5, and 1 point by frequency. Dietary habit was 39.57 $\pm$ 21.82 in male students and 42.12 $\pm$ 20.78 in female students out of total score of 100, showing higher score in female students. In the survey of dietary habits, the ratio of skipping breakfast 6 - 7 days a week in total subjects was $32.9\%$, showing a rather higher ratio of skipping breakfast, and the interest for balanced diet was as low as $13.2\%$ in total subjects. The importance of meals in total subjects was observed in the order of dinner ($47.6\%$), lunch ($40.2\%$), and breakfast($12.3\%$). In NAR of total subjects, nutrients with a score lower than 0.70 were calcium (0.64 $\pm$ 0.26), vitamin $B_2$ (0.66 $\pm$ 0.25), and vitamin C (0.69 $\pm$ 0.29) in ND of them, calcium (0.85 $\pm$ 0.43), zinc (0.89 $\pm$ 0.18), vitamin $B_2$(0.87 $\pm$ 0.34), and folic acid (0.91 $\pm$ 0.96) were nutrients with lower values. In the evaluation of nutrient intakes by the level of dietary habits, better scores of both NAR and ND were observed as the level of dietary habits was higher. There was a great difference in nutrient intakes in terms of $\%$RDA, suggesting the risk of nutritional imbalance. Based on the above results, it is considered that the improvement in dietary habits will contribute to the improvement of nutrition.

문제 정의
Therefore, this study was performed to investigate the actual condition of overall dietary life through the survey on dietary habits and nutrient intakes in some college students, and to obtain basic data for the nutritional improvement and the proper establishment of dietary habits in college students through the analysis on the influence of dietary habits on nutrient intakes.
This study was performed to investigate the nutritional knowledge, dietary habits and actual condition of nutrient in takes of college students in Gyeonggi-do area. A survey questionnaire on general characteristics and dietary habits, and daily intake using 24-hour recall method of a day were recorded by 351 college students (172 males, 179 females).
제안 방법
A survey questionnaire on general characteristics and dietary habits, and daily intake using 24-hour recall method of a day were recorded by 351 college students (172 males, 179 females).Nutrient intakes and ratios were calculated using Can-pro 2.0, from which %RDA (Recommended dietary allowances), NAR (Nutrient adequacy ratio), MAR (Mean nutrient adequacy ratio), and ND (Nutrient density) were calculated to evaluate the quality of diets in subjects.

데이터처리
The frequency and % ratio for each questionnaire were calculated and mean and standard deviation were calculated. The significance among variables was verified by using t-test, ^2-test and ANOVA-test, and the correlation among variables was obtained by using Pearson's correlation coefficient.
이론/모형
0 Professional (The Korean Nutrition Society, 2002). %RDA (Recommended dietary allowances), NAR (Nutrient adequacy ratio), MAR (Mean nutrient adequacy ratio), and ND (Nutrient density) were calculated from nutrient intakes using the 7th Recommended Dietary Allowances for Koreans (The Korean Nutrition Society, 2000) to evaluate the quality of diets in study subjects. In case of NAR, the upper limit was set as 1 and values over 1 were considered as 1.
성능/효과
4) The actual condition of nutrient intakes by the level of dietary habits showed that NAR and ND were better as dietary habits became better and the %RDA did not show significant differences by the level of dietary habit, but in general, “Good group" showed more proper intake of nutrients.
1) The average ages of study subjects were 21.84 ± 3.22 in male students and 21.42 ± 3.12 in female students, and the average heights were 176.04 ± 5.16cm in males and 162.28 ±4.65cm in females, and the average weights were 70.54 ±10.93kg in males and 54.29 ± 7.66kg in females. The BMI was 22.
2) Dietary habit was 39.57 ± 21.82 in male students and42.12 ± 20.78 in female students out of total score of 100 though not significantly different, but showed significance statistically with type of residence, health concerns, and current health status. In the survey of dietary habits, the ratio of skipping breakfast was 32.
3) In the analysis of actual condition of nutrient intakes, nutrients with the NAR less than 0.70 were calcium(0.64 ± 0.26), vitamin B2 (0.66 ± 0.25), and vitamin C(0.69 ± 0.29) MAR was 0.83 ± 0.20 showing slightly lower quality of overall diets ; nutrients with lower ND were calcium (0.85 ± 0.43), zinc(0.89 ± 0.18), vitamin B2(0.87 ± 0.34), and folic acid (0.91 ± 0.96). %RDA was lower in calcium and the standard deviation was greater, suggesting that the level of individual intake was significantly different.
78 in female students out of total score of 100 though not significantly different, but showed significance statistically with type of residence, health concerns, and current health status. In the survey of dietary habits, the ratio of skipping breakfast was 32.9%, showing rather higher ratio of skipping breakfast, and significantly different with the type of residence.
Lower values offemales in the MAR resulted from less intakes in most nutrients. It was thought that female students showed deep concern at weight control, therefore food consumption was decreased and nutrient intakes became poor. When compared to the MAR value of 0.
41). The nutrient with the greatest difference in ND depending on gender was iron, and also significant differences by gender were observed in protein, phosphorus, vitamin B2, vitamin B6, vitamin C, and vitamin E (Table 6).
1 and Table 8. The nutrients showing significant differences in nutrient intakes by the level of dietary habits were calcium and phosphorus, vitamin A, vitamin B2, vitamin C, vitamin E, and folic acid, particularly greater significance in vitamins(p<0.01). The NAR was increased as the level of dietary habits became better.
The results of dietary habits showed that the response to the frequency of breakfast was 54.0% for 0 — 2days/week, showing a higher rate of skipping breakfast, and the response to the dietary life with good combination of food was 66.1% for 0 — 2days/week. Fruit intake was high as 45% for 0 — 2 days/week, and the response to milk intake was 215 students for 1 — 2times per week, showing that food intake for balanced nutrient intake was not well practiced.
The results on the analysis of NAR for the evaluation of the overall quality of meals showed that calorie intake was significantly higher in males as 0.83 ± 0.18 when compared to that in females, and proteins, calcium, phosphorus, iron, zinc, vitamin Bb vitamin B6, vitamin E, and niacin were significantly higher in males than in females, and also the intake of other nutrients was higher in males. Nutrients with lower NAR values less than 0.
