The purpose of this study is to find out how important providing nutrition education to young students is. The study is based on the assumption that students' food behavior, nutrition knowledge and cognition of body image, weight control and nutrition education are considerably influenced by gender. A total of 495 students (249 boy and 246 girl students) were surveyed in one middle school located Siheungsi, Gyeonggido. The average height and weight of the boy and girl students are 164.6 cm, 54.4 kg and l58.5cm, 47kg, respectively. According to average BMI, the boy students($20.0kg/m^2$) are in the normal state. However, the girl students($18.2kg/m^2$) are underweight. For the status of meal intake, 52.4% of the students took breakfast everyday. Female students had dinner with lower intake frequency than males(p<0.05). For snack intake, the kinds of snack differ according to gender(p<0.05); more milk for male and more fruit for female students. The scores of dietary behavior based on Mini Dietary Assessment were 21.5/30 for male and 21.3/30 for female students. The nutrition knowledge scores of 4.6/10 for male and 4.6/10 for female students were not significantly different according to gender. The score of dietary behavior is based on Mini Dietary Assessment. The survey shows that in terms of the experience of weight control, 35.5% of the girl students have made an effort to watch their weight and 21.8% of the boy students have tried controlling their weight(p<0.0001). It turns out that the students who have been provided nutrition education are more satisfied with their body shape than those who have never been provided nutrition education(p<0.05).

The purpose of this study was to compare the dietary behaviors and snack intake between Korean and Chinese university students. The total number of participants was 520, with 267 Korean college students in Seoul and 253 Chinese college students in Shandong Province. According to the results, the most frequent place of residence was their own house for Korean students and the dormitory for Chinese students. As for healthy life behavior, Chinese university students as compared to Korean students showed a higher tendency of exercising, and lower levels of drinking, smoking, and caffeine intake. The frequency of snack intake was about 1 to 3 times a week for both Korean and Chinese college students, and the frequency of night eating was higher among Korean students than among Chinese students. The overall dietary evaluation score was higher for Chinese students than for Korean students. This study compared the overall eating habits of Korean and Chinese college students and tried to provide useful basic data for the development of educational programs that can form desirable eating habits for the health of college students in both countries.

The objective of this study was to investigate the consumption pattern of snacks-containing trans-fatty acid in adolescents living in the Kwang-ju area of Korea, and to analyze the relevance toward their eating behaviors, body composition, nutrient intakes, and consumption frequency of snacks-containing trans fatty acid. A survey questionnaire was developed in order to investigate general environmental factors, eating behavior, nutritional knowledge, and the consumption frequency of snacks-containing trans fatty acid. A total of 312 middle school students were surveyed. The collection rate was 97% and ultimately 282 cases were analyzed. Anthropometric measurements, body composition data, and nutrient intakes were also collected. The consumption frequencies for snacks-containing trans-fatty acid were negatively correlated with food behavior scores (p<0.01) however, pocket money and snack intake frequency per day were positively correlated with consumption frequency. Also, snack consumption frequency had some correlation with the subjects' anthropometric measurements and body composition data such as total body water (p<0.01), body protein (p<0.01), body minerals (p<0.01), and skeletal muscle mass (p<0.01). Finally, the consumption frequency of snacks-containing trans fatty acid was significantly correlated with calcium intake (p<0.05), it also showed correlations with vitamin A, retinol, ${\beta}-carotene$, and folic acid intake, although statistical significance was not verified.

This study was conducted to provide basic information snack intake frequency, eating patterns and current dental caries in high school students. A total of 626 students (333 males, 293 females) in Gimhae city participated in this study. The survey conducted by using a self-administered questionnaire in January, 2008. Dental caries-related information was obtained during the students' physical examination at the designated clinical hospital in 2007. The results were as follows. Sixty three point nine percent of the students were shown to have dental caries, which includes a sealant. The average number of dental caries was 3.1, which was greater in female than in male students (p < 0.001). Eighty six percent of the students were shown to maintain correct toothbrushing habits to prevent dental caries. Twenty percent of the participants brushed there teeth ‘instantly’ a meal or snack, and 27.3% of the participants brushed there teeth, gum and tongue, and 58.9% of the participants received toothbrushing education. In snack intake frequency, participants with no dental caries had preference to white milk whereas those with dental caries had preference to snacks such as chewing gums and carbonated beverages. Female students were shown to have more dental caries maybe because of their higher snack intake frequency in chocolate, cookies and chips, yoghurt and ice-cream. Dental caries did not affect eating behaviors. This study suggests that more education for correct toothbrushing and cariogenic and detergent foods are needed for better dental hygiene.

This study was performed to investigate the food behaviors of college students through a food record method. In this study, one hundred and sixty seven students of Dankook university were chosen(male:77, female:90). We collected data about nutrients intake and food behaviors. Food behaviors included a frequency of both meal and snack, meal time, eating place, person with whom they ate, reason for eating, feeling after eating, and activities during mealtime. The results of the study were summarized as follows. Energy intake per day of male and female were 2201kcal and 1781kcal, respectively. Expect for the protein, vitamin C and phosphate, nutrients were not satisfied with the RDA, especially the intake of vitamin A, Vitamin B2, and calcium was very low. Average eating frequency per day was 5.1 and meal eating frequency per day was 2.6. In addition, male ate more frequently than female did. The interval between breakfast and lunch was 295 minutes, and between lunch and dinner was 373 minutes. The places where they ate the meal and snack were mostly school and restaurant at lunch and dinner, and there was not a significant different between weekday and weekend. On weekdays, the 40~50% of subjects had a breakfast with family, and most students had a lunch or dinner with friends. During weekend, although the percentage of students who had a lunch and dinner with family were increased, a lot of students had a lunch and dinner with friends or alone. In case of reason for meal and snack, the 60~70% of subjects answered that they ate the meal for hunger, and there was not different between weekday and weekend. 60~70% of subjects felt that they eat proper, but the percentage of overeat was increased for dinner. Most students were talking with others while they had a lunch. About 20% of subjects ate only food at both breakfast and dinner and 30% of subjects were watching TV. In correlation between nutrients intake and food behaviors, the higher frequency of eating, the higher carbohydrate intake in male. In case of female, protein intake and dinner time showed the negative correlation, and protein intake and mean intervals of eating had a positive correlation. In case of male, reason for eating affected the nutrient intake, but eating place, after feeling and activity for eating had no relation with nutrients intake. But in case of female, these factors affected nutrient intake. Therefore, food behaviors had an effect on nutrients intake, and the type of effect was different between male and female.

The purpose of this study was to investigate night-time eating habits, and dietary habit and nutrient intake of university students in a particular area of Chungnam. We surveyed night-time eating status, frequency, and preference for eating foods at night in 458 university students. We divided the subjects into two groups according to their night-time eating habits and gender and compared dietary behavior, lifestyle, and nutrient intake between the groups. In total, 77.1% of the students ate a night-time snack. The major reason why they ate a night-time snack was hunger. The cost of the night-time snacks was 3,000~10,000 won and they ate mostly with their friends. The order of frequent night-time eating foods was beverage, milk and its products, snacks, flour foods, and fruits. The subjects with a night-time eating habit skipped breakfast, went to bed late, and drank alcohol more than subjects without a night-time eating habit. Total and animal fat intake of subjects with a night-time eating habit in both men and women were significantly higher than subjects without a night-time eating habit. In conclusion, night-time eating by university students may be a bad habit from the viewpoint of skipping breakfast, drinking alcohol, and eating a high fat diet. Therefore, in support of proper dietary management, it is necessary to form positive dietary habits, including night-time eating.

This study was conducted to provide current information on dietary behaviors and dish preferences of elementary school children and to suggest guidelines for proper dietary behaviors. To accomplish study objectives survey was executed using the questionnaire for 420 fifth and sixth grade school children, chosen from schools in Kangwha-gun and East River District of Seoul. A questionnaire largely consists of categories including general characteristics, dietary behavior and preferences of the subjects for some dishes. Results showed 30％ of the subjects had breakfast irregularly. A majority of the subjects took Korean style dishes of cooked rice and soup for breakfast. fifty-eight percent of subjects had a regular meal time. Imbalanced diet(avoiding specific flood group thereby causing unbalance in nutrient intake) habit group was estimated to be 47.3%. Twenty one percent had a habit of overeating. In choosing the snack, taste was considered to be a more important factor than nutrition. Advertisement of the snack was shown to be one of the Important factors in selecting the snack. The girls were more concerned about weight control than the boys. Also the girls were likely to rely on the diet to control weight since they exercised only in the physical c1ass while the boys exercised regularly. Generally, children liked animal protein containing foods and the preference for vegetables was low. In order to improve overall dietary behavior, systematic nutrition education programs reflecting sex difference should be developed. Dish preference data would be very useful in selecting substitutive dish for the s[hoof lunch menu to improve imbalanced diet. (J Community Nutrition3(2) : 69∼76, 2001)

To assess trans fatty acids (tFAs) intake of middle school students in Busan, behavior of having meals and 3 day's food record were surveyed in 800 subjects. 35.3% of subjects responded to twice a day in frequency of snack intake. Preferred snack items were ice cream (68.6%) and milk (57.0%). Subjects of dining out preferred jajangmyon (54.6%), seasoned chicken (50.5%), fried chicken (35-3%) in order when dined out. Mean daily tFAs intake of subjects was 1.68$\pm$0.04 g. Mean daily intake level of girls was 1.89$\pm$0.06 g which was significantly higher than that of boys, 1.40 $\pm$ 0.05 g (p<0.001). Naturally derived tFAs intake was 1.04$\pm$0.03 g which corresponded to 62.1% of total tFAs intake per day and industrially derived tFAs intake was 0.64 $\pm$ 0.02 g, 37.9% of total tFAs intake per day. Calorie percentage of tFAs was 0.8% and fat percentage of tFAs was 3.16%. The level of tFAs intake showed a significant difference with monthly allowance (p<0.05) and frequency of snack intake (p<0.001) in girls, which was not the case in boys. The main sources of tFAs were milk and dairy products (34.3%), bakeries (18.3%), and fish and meat products (16.2%), in order. From above results, we can conclude that tFAs intake of middle school student is not as much as that of Western teenagers. However, exact estimation of tFAs intake requires database of tFAs in broad range of processed foods commonly consumed in Korea.

To assess the relationship between serum cholesterol level and dietary intake in obese children, 50 subjects were selected as an obese group and 50 subjects as a normal group depending upon body mass index. Fasting blood samples were obtained and analyzed for serum total cholesterol(TC), high density lipoprotein cholesterol(HDLC), low density lipoprotein cholesterol(LDLC) and triglyceride(TG). The dietary intake and information on dietary behavior and family environment were obtained by questionaire using 24 hour dietary recall method for 2-consecutive days. The concentrations of TC, LDLC, HDLC and TG of obese group were estimated to be 193.3mg/dl, 122.5mg/dl, 53.7mg/dl and 86.0mg/dl, respectively. The obese group showed higher TC, LDLC, TG level(p<0.001) and lower HDLC level(p<0.001) than normal group. Food intakes in obese group were similar to those of normal group except meats & fishes(P<0.01), milk & dairy products, fruits(p<0.05), and green & yellow vegetables(p<0.001). Nutrient intakes in obese group exceeded Korean recommended dietary allowance for the corresponding ages. Saturated fatty acid(p<0.05) and cholesterol(p<0.001) intakes in obese group were higher than those of normal group. In correlation analysis, meats & fishes, eggs and milk & dairy products intakes were positively related to serum TC, LDLC and TG ; on the contrary, green & yellow vegetables and fruits intakes were negatively related to serum TC, LDLC and TG ; but positively to HDLC. Obesity index, serum cholesterol level, cholesterol and saturated fatty acid intake were positively correlated with parent's obesity index, frequency of snack per day, eating rate and late snack.

This study was intended to collect the baseline information on dietary behavior of adults to develop nutrition education program in the context of health promotion at community level. Nutrients intake of 135 housewives were assessed by 24 hour recall methods. Also food habits, nutrition knowledge and attitude were investigated by self-administered questionnaires. Our results indicated dietary intake of calcium and vitamin $B_2$ were insufficient when they were compared to Korean recommended dietary allowances(RDA). Among five food groups, intakes of milk and dairy product was inadequate as compared to the recommended amount. When we compared the fatness indices to self-evaluated meal problems, overeating and speedy eating were significantly related to fatness indices. Fatness indices such as relative body weight(RBW) and body mass index(BMI) were significantly higher in the subjects who self-evaluated their unsound food behavior as overeating. However, there were no significant differences of food habit score and nutrition knowledge among groups classified by fatness or meal problem. Body fat ratio, frequencies of night snack and skipping meal significantly increased with age. Food habit score was positively related to health-concerned attitude and active attitude toward change. We concluded that nutrition education program for housewives should include detailed strategies to modify unsound food behaviors for healthy weight.
