Many displaced North Koreans (NK) are living in South Korea (SK); however nutrition research with the displaced NK is limited. This study examined food and nutrient consumption status of displaced NK children (6-18 year-old) currently living in SK. A total of 154 children were recruited, and a pre-tested dietary behavior questionnaire, food frequency questionnaire, 24-hr recall method were used. Sex- and age-matched SK children (n = 462) randomly selected from 2009-2010 Korea National Health and Nutrition Examination Survey were used as the comparison group. This study found that more NK children skipped breakfast (37%) and dinner (11%), and ate breakfast (38.8%) and dinner (18.2%) without family members than SK children. Many NK children reported that they rarely ate bread, rice cake, hamburger, pizza, fried food, candy. NK children consumed significantly less energy and nutrients (except calcium) and obtained more energy from fat and protein than SK children. Overall index of nutrient quality in NK children, however, was generally good. Length of stay in SK and breakfast skipping rates were significantly associated with lower diet quality. Therefore, nutrition education with displaced NK children should target those who recently came to SK. How to incorporate "new" foods, generally high in energy, sugar, or fat, in healthy ways and importance of breakfast should be emphasized. The growth patterns of the displaced NK children who were born and raised in food-deprived environments and will grow in food-affluent environments of SK should be monitored for health promotion of the NK children and for nutrition policy of the future united Korea.

This study was aimed for examining the changes of eating habit and behavior according to the degree of stress of elementary school students. It was tried to identify their daily stress levels and their relevances with the changes of their eating habits and behaviosr. The subjects were 500 students from fifth and sixth grades in three elementary schools in Seoul. The students surveyed showed to get moderately stressed in general. The stress level of girls were higher than that of boys(p<0.001) in the individual area. The breakfast ratio of the low stressed group(LS) marked higher(p<0.001) than those of both the middle-(MS) and highly-stressed group(HS). In other words, the LS group had regular breakfast. The main reason why they were skipping breakfast was lack of time. The amount of a meal in the HS group was noticeably bigger than the other two groups(p<0.05) and the amount of salt and spices used was higher(p<0.01). The amount of food taken when they got stressed was increased remarkably higher in the HS group and students in that group had snacks as the way of relieving the stress. The HS group displayed higher ratio of the unbalanced diet habit. There were noticeable differences in the eating habit and behavior, i.e. the amount of meals, of salt used and whether eating breakfast or not, in accordance of the levels of stress.

The purpose of this study was to investigate meal behavior and food preferences of children with different body types. This survey was conducted using a questionnaire for 274 boys and 257 girls in the 6th grade of elementary school in Anyang city. A questionnaire method was used. Food preferences of 14 food groups were tested with 5 likert scale points. Body types were divided with weight-length index(WLI) calculated by height and weight. The cut-off point for the underweight children was 90, and that of the overweight children was 100. The mean weight of the underweight children(26.2%) was 31.9$\pm$4.0kg, and that of the overweight children(26.9%) was 49.4$\pm$6.3kg. The average BMI of overweight children and underweight children was 21.0kg/$m^2$ and 15.5kg/$m^2$respectively. Perceived health status was different based on body types, and more of the overweight children answered they are healthy compared to the underweight children, Body types were not significantly different based on parent's education and occupation. Only 56.7% of the children ate breakfast at a regular time, 60% and 42.9% of the children had their lunch and dinner at regular time, respectively. Higher percentage of overweight children had irregular breakfast(20.1%) and skipped their breakfast and dinner compared to the other groups, however only dinner was statistically significant. The most frequently answered reasons for skipping meals were 'no time to eat'(50%) and 'bad side-dishes'(17.0%). Food preference was not different among the body type groups, however rice-cake was preferred in the underweight group, as well as milk and lettuce were preferred in overweight group. The preferences for milk and grain powdered drink(misitgaru) were same as or a carbonated soft drink. Focusing pubericant, it is necessary to have a regular breakfast. With regard to the importance of nutrition and health for children, the nutrition education for meal behavior and food preference to achieve a balanced diet should be considered.

Objectives: This study was conducted to investigate the relationship between watching mukbang (eating broadcasts) and dietary and health behavior in adults who watch mukbang. Methods: The questionnaire was administered on a self-written basis through online and offline formats to 800 adults (400 men and 400 women). The contents of the survey consisted of general characteristics, mukbang viewing time per week, breakfast intake frequency, preference for menus when viewing mukbang, delivery food intake frequency per week, late meal intake frequency per week, and health behavior. The subjects were divided into three groups according to mukbang viewing time. Results: The body weight of viewers was significantly higher when mukbang viewing time was over 14 hours for both men and women. In particular, based on the BMI (body mass index), those who watched mukbang for more than 14 hours were found to be overweight. People with more than 14 hours of mukbang viewing time per week were found to prefer mostly carbohydrate-rich food and meat, while those with less than 7 hours of mukbang viewing time per week showed a higher preference for vegetables and fruits. An analysis of the frequency of breakfast eaten showed that the rate of skipping breakfast was the highest for those who watched mukbang for more than 14 hours per week, and the rate of eating breakfast daily was the highest in the case of fewer than 7 hours of viewing. In the case of high mukbang viewing time per week, the frequency of food delivery and night eating was high. When mukbang viewing time was high, the viewer's interest in health was low and the frequency of exercising too was low. Conclusions: Viewers with high mukbang viewing time showed undesirable health and eating behavior. Thus, it is believed that proper nutrition education on improving eating habits and raising the awareness of correct eating habits is necessary for such viewers.

Differences in dietary habits between Korean smokers and non-smokers were investigated using information obtained from 7,370 adults, aged 20 years and older who participated in the 1998 Korean National Health and Nutrition Sulvey. Dietary habit data including: skipping of meals, meal regularity, meal volume, snacking habits, removing fatty portions before eating foods, and dietary supplement intake were collected using a structured questionnaire by interview. Individual smoking data was also collected by interview as part of the health behavior survey. A Chi-square test was used to test the association between the dietary habits and smoking. 66.9% of the men were smokers (daily current or occasional current), while only 6.7% of women smoked. On average, 34.7% of the subjects were smokers. Smokers were more likely than nonsmokers to engage in the following dietary habits considered unhealthy: skipping breakfast, meal irregularity, large dinners, small breakfasts, frequently eating out, and eating food without removing the fatty portion. Therefore, Korean smokers should be provided education to assist them in making healthy dietary choices such as: eating regular meals, small dinners, and removing fatty Portion of foods. The survey also revealed that a substantial percentage (about 20%) of the subjects were taking some kind of dietary supplement, regardless of smoking status. It is, therefore, alto necessary to inform the general public that a balanced diet is the ideal way to obtain nutrients for optimal health.

There are many concerns about the use and abuse of both licit and illicit substances among adolescents. This study was performed to understand the drinking status and drinking behaviur of middle school students. Self reports on drinking behaviur, dietary habits and one-day dietary records were obtained from 213 boys and 202 girls using anonymous questionnaires. One hundred and forty five of 415 students(34.9%) have experienced drinking and 48.3% of them initiated it at primary school. The motivation for first drinking was different between boys and girls; ' after sacrificial rite' for boys, ' curiosity' for girls. The most plausible reasons for drinking were ' boredom' and ' stress reduction' , and they felt the strongest desire to drink when they felt ' anger or frustration' Drinking behavior was not significantly different between male and female student except in the motivation for first drinking. But interestingly, the girls drank with friends mostly, while the boys drank with their parents. Drinking-experienced students showed significantly high rates of skipping meals and in particular skipping breakfast. DVS was found as $14.71\pm{4.51}$ and $13.95\pm{4.69}$ in non-drinking and drinking, respectively. This study showed that the drinking experience of middle school students were initiated earlier in primary school, and that drinking behavior of female students was not different with that of male student.

In order to investigate the relationship among physical status, eating habits and life style, this survey was carried out by questionnaire in 1996. College students(413 cases) who resided in Chuncheon answered. The results are as follows: 1) The means of height and weight were $173.9\pm{5.0cm}$, $64.5\pm{8.3kg}$64.5$\pm$8.3kg in male students and $160.9\pm{4.5cm}$, $51.1\pm{5.8kg}$ in female students. 2) Under 20 of BMI(Body Mass Index) were 23.0% of male students and 58.3% of female students. 6.7% of males and 3.0% of females were over 25 of BMI. 3) There was a significant relationship between the type of favorite snacks and gender. There was a significant difference of BMI according to the level of the frequency and the amount of drinking alcoholic beverages. 72.6% of subjects took exercise regularly. But the BMI of subjects taking regular exercise and watching the weight tended to be higher than that of subjects not doing so. 4) Most students(78.5%) skipped breakfast, which was higher in the self-boarding students in than any other. It was because of the lack of time that they skipped their meals. This study suggests that a comprehensive nutrition education program is needed for college students in self-boarding houses and dormitories to improve their eating habits about skipping meals, and especially for female students to prevent inappropriate weight control.

An ecological study of food and nutrition was conducted among 198 children, 6 to 12 years old, of the Songmyun elementary school and Samsong elementary school, located in remote villages of Chungchun-myun, Goisan-gun, Chung Buk Province between July 11 and 16, 1988. The results were summarized as follows. In regard to frequency of skipping breakfast, 3.3% of subjects skipped every morning; 15% often skipped; and the others never skipped. The most common reason for skipping a meal was lack of appetite. 6.6% of subjects often skipped an evening meal because of delayed meal preparation by a mother who returned home late. The survey found that 5.1% of subjects skipped a lunch at school. The reasons for skipping lunch were the mother’s being too busy to prepare a boxed lunch; a school bag too heavy to carry for a long distance to school; no adequate side-dishes for the boxed lunch. Growth patterns of those children having poor food habits, were reflected in lower figures in arm circumference and weight for height. The percentage of children having meals with their family on weekdays was 84.7% for breakfast; 85.6% for evening meal. About 7% of subjects had many dislikes and 74.1% had some dislikes in what they ate; 18.9% had good food preferences. There was a strong correlation between appetite or food preferences and anthropometric measurements or nutrient intake. Boiled rice was the predominant dietary staple, and principal sources of protein taken by subjects at home were soy beans and soy products. Regarding the boxed lunch prepared at home, most popular was one with only one kind of side-dish, including kimchee. 43.4% of the side-dishes were prepared with vegetables only. As for between meal snacks, milk and milk products, fruits and breads were popular among the subjects. The survey found that the children liked fruits, yogurt, corn, Chajang noodle; in contrast, lowest preference was for soup made with bones, curried meat with rice, and aromatic vegetables. The survey discovered a local dietary characteristics; 46.2% of the children customarily ate frog meat, an unconventional food.

This study was conducted to examine food and nutrient intakes of weekday and weekend with 329 high school boys residing in Seoul using the 3-day food record. Frequency for breakfast skipping was the highest as compared with lunch and dinner skipping. Frequencies for breakfast and lunch skipping were significantly higher in weekend than weekday (p<0.05). The daily average food, vegetable food and animal food intakes were 1,327.6 g, 800.5 g, and 425.8 g, respectively. Total food and vegetable food intakes of weekday were significantly higher than weekend(p<0.05). The dietary variety score(DVS) was 20.5 in daily average, 23.3 in weekday and 15.1 in weekend, which showed significantly higher in weekday than weekend(p<0.05). The daily averages of energy, protein, fat and carbohydrate intake were 2244.9 kcal, 89 g, 72.6 g, and 311.2 g, respectively. Fat intake was significantly lower and carbohydrate, fiber, phosphate, iron, sodium, potassium, vitamin A, niacin, folate, and vitamin C intakes were significantly higher in weekday than weekend (p<0.05). The percentages of energy intake from carbohydrate, protein, and fat were 55.4%, 15.8%, 28.8% in daily average, 56.8%, 15.8%, 27.4% in weekday and 53.6%, 15.8%, 30.7% in weekend, respectively. The percentages of energy intake from carbohydrate in weekday and weekend were below 60%, and that from fat was above 27% in weekday and weekend. Carbohydrate intake was significantly higher and fat intake was significantly lower in weekday than weekend(p<0.05). Energy intakes of daily average, weekday and weekend were above 83% as compared with estimated energy requirement(EER). Intakes of dietary fiber, calcium, potassium, vitamin C, riboflavin and folate were below 75% as compared with adequate intake(AI) or recommended intake(RI). Mean adequacy ratios(MAR), an index of overall dietary quality were 0.78 in daily average, 0.80 in weekday and 0.75 in weekend. MAR of weekend showed significantly lower than weekday(p<0.05). This study revealed that the overall nutrient intake status was worse in weekend than weekday among high school boys.

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.
