The purpose of this study was to find out how much they have several aspects of food related knowledge and eating behaviors of high school students in Sungnam area. The self-administrated questionnaire was used. The result were as follows: 1. The average height of boys and girls was $172.6{\pm}0.7$ cm and $156.3{\pm}1.5$ cm respectively. The average weights of them were $62.4{\pm}0.5$ kg (male) and $47.2{\pm}0.8$ kg (female). BMI (Body Mass Index) of them were $20.74{\pm}0.14$ (male), $18.82{\pm}0.28$ (female). The average age is 16.7 years old. 2. The 66.5% of the subjects were spent more than one-third of their pocket money in buying on light meals during three times a week. There were significant differences between income level of family. Boys spent more money on each meal than girls. And significant differences were also obserbed by their residence area and Bundang residences spent more in buying snacks. 3. The rate of skipping meals was 51.2% in boys compared with 68.0% in girls. The frequencies of buying snacks instead of main meal were high in girls. Time limits in eating may possibly be the main reason for skipping meals (59.8%), especially in the morning. Skipping a breakfast becomes general eating habits in high school students, because of pressure for time to go to school. 4. It is required that parents should be taught to prepare balanced lunch box for their children because the rate of students who prepared two lunch boxes are 49.4%. 5. The students took snacks once or twice a day. They usually bought snacks in school concessions (51.8%) and they selected items of snack instinctivly. The girls ate snacks during lunch break time (31.7%) and after dinner (23.6%). Boys ate snacks after dinner (29.1%). Preference of foods were different by sex. Boys preferred bread (31.7%), milk and otherdairy products (80.8%), cola and soda (42.0%) as their snacks between meals. Girls selected biscuit, chip, beverage, coffee as their snacks, frequently. 6. BMI value of the group who ate between meals more than three times a day was lower $(18.78{\pm}0.65)$ than that of the group who ate nothing between meals $(20.71{\pm}3.79)$. 7. As for the nutritional knowledge, the students generally had higher correct rate of answer about which nutritive components of food has (76.6%). But they had lower knowledge on questions of nutritive values in food (10.6%). There was a meaningful relation between favorite food and nutritional knowledge. In conclusion, there were some problems on nutritional knowledge and eating habits among the high school students. Therefore, it was required that girls should be learned to recognize the importance of breakfast and needed to select balanced meals and snacks. And it was required that the nutrition education should be complemented to motivate and improve practical eating behaviors.

Purpose: Along with the adaptation of a Western dietary pattern and low physical activity, pediatric obesity is increasing in Korea, especially for boys. The aim of this study was to identify dietary behavior patterns and examine the snack consumption, dietary habit, and pediatric obesity by pattern groups. Methods: Boys aged 15~19 years were recruited from one high school in Seoul. A questionnaire including dietary behaviors and lifestyle factors was administered and height and weight were measured. A total of 932 boys participated except boys who had missing or incomplete response (n = 30). Three dietary behavior patterns were identified by cluster analysis; 'Healthy pattern', 'Mixed pattern' and 'Unhealthy pattern'. Results: Snack consumption differed according to dietary behavior patterns group. The healthy and mixed patterns showed higher frequencies of white milk and fruit consumption while the unhealthy pattern as well as the mixed patterns showed higher frequencies of sweetened snack and ice cream consumption. Food availability at home of each food differed according to pattern groups but showed a similar trend with food consumption. Regarding dietary habits, the mixed pattern showed higher proportion of taking dietary supplement and eating dessert while the unhealthy pattern showed lower proportion of eating regular meals and appropriate amount of meals. When the healthy pattern was set as a reference group, the odds ratio of pediatric obesity was 1.11 (CI 0.65-1.87) in the mixed pattern group and 1.88 (CI 1.14-3.10) in the unhealthy pattern group. Conclusion: In conclusion, dietary behaviors including snack consumption and lifestyle factors were connected. Unbalanced diet and undesirable dietary practice are important determinants in pediatric obesity.

This study was performed to investigate the dietary habits and nutritional knowledge of elementary school students (boy : 250, girl : 250) by gender. Frequency of skipping breakfast was high in both boys and girls. Duration of mealtime was significantly higher for boys compared with girls (p<0.001). Regularity of meals was not significantly different between boys and girls. Reason for irregular meals was 'no appetite' for both boys (39.6%) and girls (40.0%). Unbalanced diet was high in both boys (60.8%) and girls (59.6%), and problems related to dietary habits were in order of 'unbalance diet', 'irregular mealtime', 'overeating', 'skip a meal frequently', and 'eat out frequently'. Frequency of snack intake was significantly higher for girls compared to boys(p<0.05). The criterion for selecting snacks was higher for 'nutrition' compared to 'good taste' for both boys and girls. Frequency of eating out was statistically insignificant, and eating out preferences were in the order of 'Korean food', 'western food', and 'Chinese food'. Eating behavior 'eat meat, fish, egg, tofu every meal' was significantly higher for boys compared to girls (p<0.01). 'Healthful' response rates were 57.6% for boys and 58.8% for girls. Practice level of nutritional knowledge was significantly higher in girls compared to boys (p<0.001). To establish good eating behaviors, we should develop systematic and continuous education programs.

This study has been carried out to obtain information related to food habits and snacking behaviors including health related behaviors. The subjects were 300 middle school students (144 boys and 156 girls). The results were as follows: Average height and weight of boys were 162.3 cm and 54.1 kg respectively. Those of girls were 159.8 cm and 49.0 kg respectively. 59.0% of the subjects of the subjects had 10,000-30,000 won as monthly allowances and their subjective health condition was good (55.7%). In the regularity of meal, 47.0% of the subjects had twice a day, the main reason for skipping meal was insufficient time to eat due to oversleep (54.3%). Most of the subjects (75.0%) had a prejudice in food selection because of a bad taste. 62.0% of the subjects ate snack between meals more than three times a week, because they were hungry, good taste and habitual. The criteria of choosing snack were taste, nutrition and quality of food. Food as snacks they frequently had fruits, milk and milk products, cookies, chocolate in order. Boys had more french fries than girls, girls had more fruits, cookies and chocolate than boys. Average food habit score of boys (49.27 ${\pm}$ 7.53) was higher than that of girls (48.54 ${\pm}$ 7.81). The group who had a higher food habit score, they had more fruits and less soft drink as snacks, lower BMI, and also less monthly allowance than the group who had a lower food habit score. This study may provide basic information on eating habits of middle school students, suggests that nutrition education or counseling can improve food habits and develop positive behaviors toward healthy diets.

This study investigated the correlation between eating behavior patterns, including eating-habits, food preferences, snack intake levels, and eating-out frequency and stress levels in high school students (males 174 and females 122) in Seoul. Analysis of eating-habits showed that eating-irregularity and eating-speed increased with elevated stress levels in both males and females under stress. The size of meals decreased in males, whereas it increased in females under getting stress (P<0.01). Preferences for sugar, hamburgers, and pizza also increased in both males and females under stress. Eating-out frequency decreased in males with a high stress level (P<0.01), whereas it increased in females. As for eating-out partners, males did not show any changes, whereas females preferred friends to family when under stress. Eating-out expenses also increased in both males and females, particularly in females with a high stress level (P<0.05). Males under increased stress showed effective stress reduction by increasing food intake, whereas females under increased stress showed less effective results. Consequently, high school students under high stress, particularly females, showed negative changes in eating behavior patterns, including irregular eating-habits, increased instant food and snack intakes, and increased frequency of eating-out. Therefore, development of appropriate programs for reducing stress and persistent nutrition education to promote good dietary behaviors are required.

To investigate the dietary behavior and food preference by the obesity index, 524 children (male 265, female 259) from 4 elementary schools in Gyeonggi area participated in this study. The overweight group included more boys (52.5%) than girls (47.5%). The overweight group had significantly higher values in height, weight, Obesity index (OI), Body mass index (BMI), and Rohrer index (RI) than the underweight or normal weight groups. The majority (43.4%) of children showed 11-20 minutes of eating time, and boys ate significantly rapidly than girls (p<0.00l). Snack was consumed 2-3 times a day, with the preference principally for ice-cream and cookies. The frequency of eating out was 1-2 times a month, representing 71.4% of subjects, and 73.3% of children preferred Korean style meals, followed by Western, Chinese and Japanese foods. Twigim (frying) was the preferred cooking method for vegetables, fish and meat. The food preference study showed that Ssalbap, Hyunmibap and Boribap were preferred in the rice group. For one-dish foods in the rice group, Jjajangbap, Kimchibokeumbap, Bokeumbap were preferred, with the tendency that boys preferred significantly more Curry rice (p<0.05) and Chickenbap (p<0.01) than girls. The preference for guk, jjigae, and tang group showed that Soegogimiyeokguk, Chamchikimchijjigae were preferred Boys preferred significantly more Samgyetang (p<0.05), Haemultang (p<0.05) and Yukgaejang (p<0.01) than girls, and girls preferred significantly more Kongbijijjigae (p<0.05) than boys. It is considered that organized and continuous nutritional education beginning in childhood, is necessary to for the development and formation of desirable dietary behaviors.

The purpose of this study was to investigate the association between dietary behavior and temperament & character in preschool children, and to offer basic data that can be applied for nutrition education and counseling. A total of 211 parents of preschool children aged 3~5 years performed the Korean version of Preschool Temperament and Character Inventory (K-psTCI), a questionnaire based on Cloninger's seven-factor model of personality, along with a questionnaire about the dietary behaviors of their children. K-psTCI represented seven factors such as harm avoidance (HA), novelty seeking (NS), reward dependence (RD), persistence (P), self-directedness (SD), cooperativeness (CO), and self-transcendence (ST). The subjects were divided into either the high rank group or low rank group based on the mean score of each factor. The high rank group of HA showed significantly less physical activity and less appetite than the low rank group of HA. The children in the high rank of NS were more likely to have picky eating and a late night snack. The children in the low rank of SD or CO were more likely to have undesirable dietary behaviors, such as picky eating, too much snacking, and lower appetite than those in the high rank of SD or CO. In conclusion, individual temperament & character in preschool children may be associated with their dietary behavior, and understanding temperament & character in children may be important facts to screen and to develop an effective nutrition education program for children.

This study was designed to implement and evaluate a nutrition education program for hypertensive patients aged between 50 and over. Nutrition education consisted of four sessions and, 35 out of 51 patients completed all education sessions at the public health center. To assess program effectiveness (effectively), data about blood pressure, blood cholesterol, anthropometry, nutrition knowledge, eating behavior and dietary intake were collected before and after nutrition education. Data were analyzed using SAS package (ver. 9.2) and significant difference was evaluated by paired t-test, x2-test and Wilcoxon signed rank test. Blood cholesterol was significantly reduced from 200.7 mg/dL to 188.7 mg/dL after nutrition education, although there were not significant changes in blood pressure or blood triglyceride level. Weight (p < 0.05), % body fat (p < 0.001), BMI (p < 0.05) were significantly reduced, especially in women, after nutrition education. Nutrition knowledge was increased significantly (p < 0.05), and some eating behaviors such as 'having fruits & vegetables for snack' and 'having brown rice, barley rice than white rice' were improved after nutrition education (p < 0.05). Sodium intake was reduced from 3,888.9 mg/day to 3,157.4 mg/day after nutrition education (p < 0.05). Except protein and iron intakes, the nutrient intake of hypertensive patients was much below the recommended level for Koreans. Dietary intakes of most of nutrients were not significantly different between pre-test and post-test. It appeared that nutrition education for the aged hypertensive patients was effective in reducing the percentage of % body fat and BMI, increasing the nutrition knowledge and some dietary behaviors. This nutrition education can be implemented at public health centers or senior centers for hypertensive patients.

Objectives: This study was conducted to investigate the snack intake and brushing behavior according to the oral health education experience in some schools in Busan, and to investigate whether the oral health education experience affects the snack intake and brushing behavior. Methods: This study surveyed the entire fourth grade of elementary school in two districts by participating in university-linked oral health education activities run under the jurisdiction of the education office business to examine changes in the behavior of elementary school students in their snack intake and toothbrush. The survey was conducted on oral health education in elementary schools, prior oral health education experience before and after the activity, whether or not the brushing classroom was operated, and contents related to eating snacks and brushing behaviors. Result: Among the general characteristics of some schools in Busan, 69.9% of students have experience in oral health education and 30.1% of people have no experience in oral health education. 20.0%, 16.3% were 'normal' and 63.7% were 'helpful'. The brushing behavior according to the oral health education was 44.9% in the number of brushings, 44.9% in the number of brushings, 45.7% in 2-3 minutes in the time of brushing, 41.2% in the brushing method by sweeping the brush up and down. In the daily brushing period, 'after breakfast' was the highest at 72.3%, and the parent's brushing instruction was 'to lead' at 65.1%. The amount of sugar in subjective snacks was the highest with 60.6% of sugar content, and the parents had the highest level of 52.2% for parents' snack intake. This result was more significant than the students without oral health education experience. Conclusion: Based on the results of this study, the number and time of brushing, the method and timing of brushing according to the experience of oral health education. Students who had oral health education experience higher than those who did not have oral health education, but had a lower tendency to brush after lunch at school and before going to bed. For better oral health, the effect of oral health education will be better if the school has more systematic toothbrushing at lunch time and parental guidance at home.

This study investigated the nutrition education realities and nutrition status of children in community child centers, by analyzing the status of nutrition education, nutrition quotient (NQ), and the level of maintaining dietary guidelines. The subjects were 173 children from grades 1 to 6, enrolled in community child centers, Jinju, Kyungnam. The NQ was examined by a questionnaire, which was a checklist of 19 food behavior items. The distribution of scores (out of 100) in the nutrition quotient were as follows: total score of NQ was 59.4, balance 56.6, diversity 60.6, moderation 65.6, regularity 60.9, and practice 56.7. Nutrition quotient was higher in the higher graders due to significant differences in the area of variety. The level of maintaining dietary guidelines was higher in girls, especially in the area 'eat politely with family', and higher amongst the upper graders in the area 'have safe snack wisely'. To improve the eating habits and nutritional status of the children in community child centers, their nutritional state should be checked with regular and systematic education, and their nutritional management should be pursued continuously. Since the assessment of the eating behaviors and the nutritional state of children is important at home as well as in schools and community child centers, nutritional education should be further extended to the parents and their care givers. This study can be implemented as basic material for the nutritional education of children, to minimize the dangers of malnutrition and to help build up the right eating habits amongst children in community child centers.
