This study was performed to investigate the eating habit, body image, and weight control behavior by BMI in Korean female high school students. Data on the 16,574 subjects was obtained from the sixth Korea Youth Risk Behavior Web-based Survey (2010). Only 52.2% of the subjects had regular breakfast. The rate of skipping breakfast was higher in the underweight group than in the obese group, but the rate of skipping dinner was on the contrary to this. Underweight students had a higher intake frequency of fruits, fast food, instant noodle, and snacks than the obese groups. 3.5% of underweight students considered themselves to be overweight or obese. 53.4% of obese students considered themselves to be overweight. The experience of weight control increased according to BMI, but underweight students considered weight control as an effort to be slimmer. Meal restriction was used more frequently to control weight. The perceived stress level was higher in obese student, especially due to appearance. Therefore, an appropriate, integrated and personalized high school nutrition program should be established for proper body image perception and to develop the self-esteem of female high school students.

The purpose of this study was to investigate the change in food habits of girl students 1985 and 1998. A similar study had been conducted in 1985 and this study was carried in May, 1998 using the questionnaires. The subjects were 746 female students in middle school, high school and university students living in Jeonbuk region. The average score of food habit was $4.11{\pm}1.63$ out of a possible 10. This averge is lower than the 4.91 score in 1985, especially the score of university students lowered from 4.80 points to $3.52{\pm}1.58$ points. The correlation coefficient between the score of food habit and standard of living, utilizing increase as compared with the 54.9% in 1985. The most preferred side-dish changed from fried food to Kimchi. The preference of snacks was not changed. Eating bread increased at breakfast but eating noodles increased at lunch. University students' lunch basket preparation ratio decreased from 32.6% to 3.3%, so they had more noodles at refectory than lunch basket. The reason for skipping breakfast did not changes, but skipping lunch changed from annoyance due to lunch basket preparation to lack of time and no appetite. Skipping supper was changed from missing time to weight control. Having supper at home decreased from 96.6% to 75.9%. Substitution food on no preparation of lunch basket was changed from bread to noodles. The preference for biscuits and snack did not changes but fewer students preftered bread and fried food. In order to improve the nutritional status of the girl students, they must establish good food habits, especially by eating 3 regular meals per day and balancing their diet they should also be notified that severe weight control is very harmful for health.

The purpose of this study was to explore dietary attitude among middle school students by sex. The subjects were collected from 211 boy students and 198 girl students in the city of Kunsan, Jeonbuk province. The mean age of the subjects was 13.7 years old. The average score of food habit was 4.61 $\pm$ 1.92. The average score of food habit of boy students was higher than the score of girl students. The correlations between the score of food habit and father's education level. family income, and nutritional supplements were positive. The correlation between the scores of the nutrition knowledge and father's education level was also positive. On the other hand the mother's occupation did not have any influence on the scores of food habits and the scores of the nutrition knowledge. As a staple food, cooked rice was preferred on boy and girl students at breakfast(82.7%) and supper(94.3%). The preference of snacks was fruit and fruit juice. The reason of skipping breakfast was the lack of time and no appetite, and skipping lunch was due to no appetite. Lastly the main reason of skipping supper was playing computer on boys. on the other hand no appetite and weight control on girls. In order to improve the nutritional status of the middle school students, they must establish good food habits by eating three regular meals per day and balancing their diet. Also they should be notified that severe weight control is very harmful for health. This study indicate that nutrition education and correct information for body image. balanced diet. regularity of meals and food selection are required for middle school students at both school and home.

The purpose of this study was to evaluate the dietary attitude and food behavior of elementary, middle and high school students in Korea. The subjects in this study were 7,698 boys and girls in large cities in Korea. The questionnaire was made and distributed to the students to answer the questions. Followings are the results of this study : 1) Father and mother's average ages were 45 and 41 years old, respectively. 2) Most students thought dietary life was more important than clothing or residentary life. Dietary habits such as irregularity of meal, frequencies of skipping meal and of eating out increased in higher grade than in lower grade, and in girls than in boys. 3) Most students, especially in elementary school, recognized that their own bad dietary habbit was unbalanced diet. Irregular meal time and eating too much were also pointed out as problems by middle and high school students. 4) Most students thought that the most effective meal for health was breakfast, but they replied the tartest meal as dinner. 5) Students tended to prefer Korean style food. Cooked rice and kimchi, ramyun, and pizza were ranked the most preferred food when they were hungry. 6) Elementary school students ate meals more regularly than higher grade students, and girls ate meals more regularly than boys. 7) Skipping rate of breakfast was higher than that of lunch or dinner, and the percentage of meal skipping students was increasing with grade elevation. No time to eat or eating between meals was the reasons of irregular meal time. 8) Frequency of dining with family was decreased, but frequency of eating out with friends was increased with increasing grade. The gravity of dining out is increasing rapidly in Korean adolescents. Therefore, nationwide nutrition education policy is necessary to constitute a right dietary environment and a desirable dietary altitude.

The purpose of this study was to investigate the effects of alcohol intake on nutritional intake status among the college students. The subjects were divided three groups; no-alcohol group(n=78), alcohol group(n=113), and high-alcohol group(n=82) according to intake and frequency of alcohol. And they were observed characteristics of alcohol drinking, dietary behavior and attitude, and nutrient intakes using questionnaires. The frequency of skipping meals in breakfast in high-alcohol group were higher than in other two groups(p<0.01). There were no significant differences in frequency of skipping meals of lunch and supper, reason why skipped meals, and total score of dietary attitude among three groups. However, the score of dietary attitude about no heavy drinking and smoking in high-alcohol group was higher than in other two groups(p<0.01). There were significant difference in vitamin B2 intake, alcohol intake, and energy intakes from carbohydrate, lipid, and alcohol among three groups(p<0.05, p<0.05, p<0.01, p<0.05, p<0.05). Compared energy intake of high-alcohol group with other two groups, intake from carbohydrate was low and intakes from lipid and alcohol were high. In the nutrient density, plant protein and carbohydrate in no-alcohol group, lipid and vitamin B2 in alcohol group, and animal lipid in high-alcohol group were highest among three groups. NAR and MAR were not significant difference among three groups except that NAR of P in alcohol group is highest among three groups(p<0.05). In conclusion, students high consuming alcohol have unhealty dietary behaviors in the light of high frequency of skipping breakfast, undesirable dietary attitude of alcohol drinking and smoking, and low energy inake from diet. Therefore, this results should be considered in meal management and nutritional education for student of high alcohol consumption.

This study was performed to investigate the dietary habits and satisfaction of school foodservice by high school type (academic high school students (AHSS) : n=200, vocational high school students (VHSS) : n=200). Frequency of skipping breakfast was significantly higher for VHSS compared with AHSS (p<0.001), and reasons for skipping breakfast were significantly high for 'lack of time' and 'habitually' in VHSS (p<0.01). Duration of mealtime was significantly higher for AHSS compared with VHSS (p<0.001). Frequency of snacking was high in both AHSS and VHSS, and after dinner was the most common snack time for AHSS (p<0.001). Most commonly cited methods for improving dietary habits were 'frequently skipping meals' in AHSS and 'irregular meals' in VHSS. Reasons for leaving leftover foods were 'no taste' in AHSS and 'side dish I don't like' in VHSS (p<0.05). Satisfaction of school foodservice was significantly higher for AHSS compared with VHSS (p<0.05). Most commonly cited methods for improving school foodservice were 'varied menu' in AHSS and 'food taste' in VHSS (p<0.05). Commonly cited dietary motivations were 'preference' in AHSS and 'resolving starvation' in VHSS (p<0.001). As preference is an important factor, new menu development and continuous nutritional education should be necessary for menu diversity in order to raise satisfaction by using foods with high preference and superior nutrition.

This study was carried out to investigate the effects of breakfast service on nutritional status, hematological status, and attentiveness of children in low-income families. The subjects were 19 boys and 13 girls between 7 and 11 years old. The subjects were divided into a control group and a breakfast service (BS) group, in which 12 boys and 5 girls received breakfast from February 1 to December 31, 2010. The results can be summarized as follows: intakes of energy, protein, carbohydrate, calcium, iron, zinc, vitamin A, vitamin $B_2$, niacin, and vitamin C in the BS group were significantly higher than those in the control group. In the BS group, the intakes of calcium, folic acid, and vitamin C were lower than 75% of recommended intake levels. There were no significant differences in the total blood protein level and total cholesterol level between the BS group and control group. A blood albumin level was significantly higher in the BS group than in the control group. Systolic blood pressure was higher in the BS group than in the control group, whereas the diastolic blood pressure showed no significant difference between the groups. A dietary attitude score increased according to breakfast service and nutritional education. No significant differences were found in the capacity value and continuity value between the two groups, but the control value was significantly higher in the BS group than in the control group. Therefore, to sustain the effect of breakfast service and improve nutritional status for children skipping breakfast in low-income families, nutrition intervention services, as well as legal and financial support by the government should be provided.

This study was conducted to develop the standard breakfast menu for those weak groups having insufficient breakfast intake. The following three target groups are classified as: 16-19 years old high school male student, 20-29 years old female who have job or college students, 20-29 years old male or female who have job (double income family). While developing menus for each target groups, we applied several basic guidelines for meal planning as follows: Nutrient intake level was set to $\graction one-Third$ of RDA, while the energy level to $\fraction one-quarter $ of RDAs. Most Sequent meal pattern of Koreans was adapted; Suitabilities of appropriate serving size and cost for middle-income families were considered; Domestic foods and ingredients were used. We developed 24 menus summed by 2 menus for each season and three target groups. When evaluating the menus, most of the breakfast menus were sufficient of nutrients as a meal for the subjects. Three food groups such as grain/starch group, meat/fish/egg/bean group, vegetable/fruit group were included in all menus. Even though milk/dairy products group was not excluded for some menus, other calcium substitutes like anchovies were used. Oil/nut/sugar group was used to a minimum. The average number of foods for each menu was 12.8, which ranged from 10 to 17 depending on the menus. The average weight of the menus including soup was 822 g, 633 g and 730 g for each target group, respectively. The average price of the menu ranged from 2,000 to 3,500 won per person. The above results could be applied at home as well as foodservice institutes and furthermore could offer information for developing breakfast-substituting food products.

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.

This study was carried out to find out differences about meal conditions and food preference between non-obese and obese elementary school children. Ten children(non-obese 5 and obese 5) from each of the nationwide 192 schools were surveyed by self-developed questionnaire. Total of 1,767 questionnaires(815 from non-obese and 952 from obese children) were collected and data were analyzed using SPSS 12.0 program. The results of the comparative analysis were summarized as follows. There was not significantly different in height between non-obese $group(151.0{\pm}12.5cm)$ and obese $group(151.2{\pm}12.3cm)$. But BMI was significant difference between non-obese $group(18.0{\pm}2.2cm)$ and obese $group(27.3{\pm}3.2cm)$. Economical status was not significantly different between 2 groups. But educational level of parents and mother’ job were significant differences between 2 groups. Only 2/3 of the subjects reported to have breakfast at regular basas, regularity of having breakfast was not significantly different between 2 groups. Also regularity of having lunch during vacation was not significantly different between 2 groups. But Reasons of skipping breakfast and lunch were significantly different between 2 groups. Regularity of having dinner, reasons of skipping dinner, intake amount in dinner, and frequency of having snacks were significantly different between 2 groups. But the time required for lunch and dinner were under 20 minutes of 60-80% of the subjects, and were not significantly different between 2 groups. Non-obese group have liked fast foods, fruits & juices, sweets, and cakes & cookies than obese group. Obese group have liked meat & meat products and ramyeon, but they have not eaten those foods frequently because of anxiety about being more fatty. These findings suggested that nutrition education programs include different strategy according to obesity and obese prevention program is needed for non-obese school children.
