This study investigated the interrelations among acculturative stress, recognition, preference and eating frequency of Korean traditional food by Chinese students in Korea. The acculturative stress score was $3.06{\pm}0.32$, 'homesickness' score was the highest ($3.92{\pm}0.62$) and 'guiltscore' score was the lowest ($2.28{\pm}1.04$). The rate of preferred for Korean food was low (20.5%). The places for eating Korean food were 'restaurant' (49.6%) and 'school cafeteria' (41.1%). The cooking experience regarding Korean food was 45.0% and they had cooked 'Bulgogi' (26.7%) and 'Bibimbap' (21.9%). The recognition score for Korean traditional food was $0.70{\pm}0.27$. The preference score for Korean traditional food was $3.14{\pm}0.54$, and the favorite foods were 'Galbi' and 'Galbitang' while 'Ggakdugi' was the lowest. The eating frequency for Korean traditional food was $2.15{\pm}0.82$, and 'Baechukimchi' and 'Bibimbap' were comparatively high. The acculturative stress showed no correlation with the recognition, preference and eating frequency of Korean traditional food. The recognition of Korean traditional food correlated positively with the eating frequency (r=0.175, p<0.05). The preference of Korean traditional food had a significant effect on eating frequency (r=0.274, p<0.001), and the highest positive correlation was shown in 'Ddeokbokki' (r=0.470). The explanation power ($R^2$) of recognition and preference on eating frequency was 0.098. This study showed the interrelations among recognition, preference, and eating frequency of Korean traditional food except for acculturative stress.

Sister chromatid exchanges(SCE) in peripheral lymphocytes is recently used as a biomarker for increased cytogenetic damage in smokers. The purpose of the investigation was to determine if there were any relationships between dietary factors and their DNA damage as measured by SCE test in a group of 62 male cigarette smokers and 36 non-smokers. As expected, smokers as compared with non-smokers had high SCE levels (10.59$\pm$0.21 versus 9.23$\pm$0.17 SCE/lymphocytes ; p<0.05). No significant relationships were observed between SCEs and age in smokers and non-smokers. In smokers, SCEs were negatively correlated with egg frequency score(r=-0.336) and total food frequency scores(r=-0.283). In non-smokers, SCEs were positively correlated with white vegetable frequency score(r=0.333) and instant food frequency score(r=0.382). There was a positive association between SCEs and the history of coffee intake of smokers(r=0.318). SCE frequency was not influenced by any other dietary factors considered ; dietary diversity and quality scores, alcohol consumption, use of processed foods and intake of burned food. No significant relationships were found between SCEs and serum cholesterol or other hematological parameters of the subjects. These results indicate that increased egg frequency score, total food frequency score which reflects dietary quality, and decreased coffee intake may reduce cancer risk by preventing smoking-induced DNA damage as reflected by sister chromatid exchanges in human lymphocytes.

The purpose of this study was to provide the basic information for developing sugar related nutrition education programs for children in child-care facilities and their parents. The results showed that the total score of parent's dietary attitudes towards sugar-rich foods was 17.94 and the total score of parent's nutritional knowledge was 3.67. A positive relationship was observed among items of parent's dietary attitudes (p<0.01), and some correlations were also observed between the total score of parent's nutritional knowledge and the total score of parent's dietary attitudes (p<0.05 or p<0.01). The total average score of children's eating behaviors for sugar-rich foods was 23.98, and the item with the highest score was 'I often eat candy, chocolate and jelly'. For children, food that received the highest preference was chocolate, and soft drinks received the lowest preference. The most frequently consumed food item was candy or caramel, and the least frequently consumed food item was soft drinks. There were positive correlation among the total score of children's eating behaviors, food preferences, and food intake frequency (p<0.01). When parent's tried to reduce the sugar intake, children's total score of eating behaviors (p<0.001) and food intake frequency (p<0.001) for sugar-rich food was lower. We conclude that parent's dietary attitudes may influence children's eating behaviors, food preferences, and food intake frequency for sugar-rich foods.

In order to investigate food purchase frequency of elementary school children and its related ecological factors, 431 4th, 5th and 6th grade elementary school children and their mothers, living in Seoul and Daejon, small city and rural area of Chungnam Province, were participated in this study. The subjects and their parents were surveyed by a self-recording questionnaire about food purchase frequency and some ecological factors. Average height and weight of the subjects by gender and grade were similar to or a little bit more than the 1998 Korean Growth Standard. According to relative body weight, 30.6% and 10.8% of the subjects belonged to under-weight and obesity categories, respectively. Of the subjects, 46.9% used PC telecommunication or internet, 53.8% of them used it for less than an hour per day, and 46.4% watched TV for 2 to 4 hours a day. About 42% of the subjects spent 500 Won or less daily to buy snacks. A half of the subjects took snacks once a day because of hunger. Mothers' nutrition knowledge score was averagely 8.16 out of 13 full score and the average attitude score was 43.22 out of 50 full score. Foods purchased more than once a week were milk and yoghurt, cookies, ice-cream, ramyun, and gum in order. Family income, parents' education level, mothers' nutrition knowledge and food attitude score, students' snacking frequency and TV watching time showed significant correlations with purchase frequencies of some individual food items. In conclusion, the elementary school children considered taste most important rather than nutrition in buying snacks and most frequently bought carbohydrate foods and concentrated sugars except milk. Ecological factors such as mothers' nutritional knowledge and food attitude, TV watching time and snacking frequency had influenced the children's food purchase frequency. Accordingly, it is necessary to educate both children and their mothers about good food purchase and the importance of snacking.

The purpose of this study was to investigate the dietary factors associated with characteristics of attention deficit hyperactivity disorder (ADHD) in upper-grade elementary school students. The study subjects were 397 students, and 52% of total study subjects were boys. The risk for developing ADHD was assessed by using a DSM-IV questionnaire. Boy's ADHD score was higher than that of girls (p<0.001). Subjects were divided into two groups according to the median of the ADHD score in boys and girls. The high ADHD score group showed higher frequency of skipping breakfast and a lower score for good dietary habits, as compared to the normal group. Further, the high ADHD score group showed higher frequency of processed food intake with lower frequency of vegetable intake, as compared to the normal group. These results suggest that undesirable eating habits and frequent intake of processed foods may be associated with higher risk of developing ADHD in elementary school students.

The purpose of this study was to find out the relationships among the eating behavior, the nutrition knowledge & the physical growth, and factors influencing each of them in middle school students. Eight hundred three boys and girls, who were sampled from the third graders of 6 middle schools located in Taejeon and Ahnmyeondo, were asked to fill out the questionaire. The statistics used for data analysis were Frequency, Percentage, Oneway, Crosstabs, Chi-square($X^2$), t-test, Pearson Correlation, Regression, and Path analyses. The results are summarized as follows: I. The asked students showed the significant difference in frequency intaking food and the eating attitude depending on sexual distinction and area. The girls got higher frequency score(intaking food) than the boys did and the students in Taejeon got better eating attitude score than those in Ahnmyeondo. Also, the girls got higher nutrition knowledge score than the boys did and the students in Taejeon got higher nutrition knowledge than those in Ahnmyeondo. 2. The higher the economic level was, the higher the frequency score(intaking food) was. Also, the students whose father had the occupation involved in the tertiary industry and better school ing made higher nutrition knowledge, eating attitude, and frequency intaking food than others. The students whose father had the occupation involved in the tertiary industry and better schooling were taller and heavier than others. 3. The variables influencing on the frequency intaking food were father's school ing, father's occupation, economic level, sexual distinction, eating attitude. The variables influencing on eating attitude significantly was only the birth order. The variables influencing on the height were sexual distinction, residential area, eating attitude, frequency intaking food, father's schooling. Also, the variables affecting the weight were sexual distinction, father's schooling, eating attitude, frequency intaking food.

Especially, the teenage period, an important lifetime to develop both physically and mentally, needs to be helpful to promote the growth of the body and to keep a well-balanced mind through a balanced and nourishing diet. It is well known that the western style fast food is the most liked meal by teenagers. Wrong recognition about fast food and its frequent intake by adolescents can lead to unbalanced diet and food behaviors which may also connect with a poor impact on their personalities as well as their physical health. In this study, therefore, relationships between fast food intake frequency and food behavior, sociability, and personality, such as anger expression, were surveyed from 1,295 adolescents (666 in Seoul, 316 in Changwon, and 313 in rural communities), and then analyzed using SPSS program. The results are shown as follows. The fast food preference score and the fast food intake frequency score showed no differences between male students (22.9/30, 14.4/30 respectively) and female students (23.0/30, 14.0/30 respectively). But, the fast food preference score correlated positively with the intake frequency score (r=0.304) significantly (p<0.001). The more frequently eating of fast food group showed significantly lower scores (r=-0.233, p<0.001) in food behaviors. The frequency of fast food intake had no relationships with sociability, but it had a significantly effect on anger expression (r=0.213, p<0.001) and control (r=-0.l47, p<0.001). From these results, we could see the necessity of various nutrition education programs to build proper eating-out habits and also more studies are needed to find the relationships between fast food intake and growth and personality.

This survey was carried out to Investigate the effects of dietary attitude on the nutrition knowledge, food habits, the daily average nutrient Intakes and the intake of Instant food, convenience food & fast food between college women and their mothers. Questionnaires were completed by 214 college nutrition majors and also by their mothers numbering at 173. College women's mothers showed a better average in meal time regularities per week than that of. college women. Also it is the fact that the college women had a higher frequency rate of instant food and fast food than their mothers. In the case of both college women and mothers if they eat at regular meal times they had a higher score in food habits. But the daily average nutrient intakes was not significant because of the fact that the meal time regularity and nutrient intakes 414 not concise. The higher frequency of instant food intake had a lower score in food habits and nutrition knowledge. The higher frequency of fast food Intake had a higher food habits score but it also had a lower score in nutrition knowledge. As in the intake of instant food and convenience food the college women had a higher Intake frequency. In the dietary pattern the college women they liked to eat (lour foods. But their mothers liked to eat Korean foods. The selective motive and the degree of satisfaction of food service industry product was for convenience and time saving. The food service industry products were found to be unsatisfactory in nutrition and sanitation. Therefore we must be more aware of preventing the disappearance of Korean traditional foods. For the continuing development of our dietary culture we need to have the food service industry to develop more suitable diet for Korean.

This study was conducted using a self boarding questionnaire survey to investigate body image perception, dietary habits and nutrient intakes according to interest level in health of female university students in Masan area (n=302). The subjects were divided into 2 groups according to interest level in health ('High' group, n=101, 'Low' group, n=201). Body image according to BMI was significantly different regardless of interest level in health (p<0.001). The answer percentage indicated that the purpose of weight control is health, regular use of the scale, and regular exercise were significantly higher in the high group (p<0.05). Nutrient knowledge score (p<0.01) and food frequency score (p<0.001) were significantly higher in the high group (p<0.01). There were no significant differences in nutrient intake, but intake, NAR and INQ of vitamin C were significantly higher in the high group (p<0.001). Nutrition knowledge score (p<0.01), food intake frequency score (p<0.01), and INQ and NAR of vitamin C (p<0.01) were positively correlated with the interest level in health. These results will be useful as a basis for the development of effective nutrition education programs in order to increase interest level in health and apply well in real life what have learned through the correct nutrition knowledge.

The menu planning is closely tied to the acceptability of the food and the satisfaction of the food service system to its client, therefore national school lunch program(NSLP) menu should consider the food preferences of the students. To provide appropriate information and guidelines about desirable NSLP menu planning, the comparison between the frequency of NSLP menus and food preferences of the students was performed, NSLP menus with cooking method of 776 meals were collected from 10 elementary NSLP schools in Seoul and Kyunggi province, and food preference data was surveyed with 1618 elementary school students from 4 NSLP schools in Korea in 1995. According to the cooking methods, NSLP menus served Kimchi(98.3%), rice(71.4%) and soup(71.1%) frequently. Based on the food groups, NSLP menus served vegetables most frequently(188%), followed by grains(101.4%), milk(100%), meat(57.3%), fruits(50.3%), and so on. By Spearman Rank Correlations analysis, the serving frequencies of vegetable side dishes(r=.33, p=.05) were positively correlated with the students' preference score. According to the cooking method, the serving frequencies of steamed dishes(r=1.0, p=.00), salads(r=1.0, p=.00), Kimchi(r=.85, p=.01) and rice one-dish meal(r=.80, p=.10) were positively correlated with the students' preference score. However, the serving frequencies of the main dishes(r=.13, p=.57) and soup group(r=.15, p=.57) were not significantly correlated with the students' preference score. Even though the serving frequency of fruit were negatively correlated with the students' preference score(r= -.80, p=.10). These results indicated that the NSLP menu planned the vegetable side dishes in accordance with the students' food preferences, but it planned the main dish, soup group, and meat side dish group discordantly. Therefore further efforts are needed to involve the preferred cooking methods for increasing the food acceptability. It could be used for the basic guidelines for menu planning of NSLP, and for the future improvement of NSLP in Korea.
