The aim of this study is to estimate the prevalence of obesity and factors with it Ulsan secondary school girls. A cross-sectional study involving a sample of 485 students aged 12 to 15 years was obtained form secondary schools. Obesity was determined using body mass index(BMI=wt/Ht$^2$). The findings revealed that the average BMI was 19.3, and 4.5% of girls were either overweight and obese(BMI$\geq$25). Subjects were grouped into three categories based on the BMI, sibling obesity, self-consciousness of obesity, eating patterns such as eating snack after dinner and prejudice in food selection, and food frequency score were significantly associated nth BMI, while nutrition knowledge score was not associated with BMI. The fact that several social, environmental and health factors are associated with obesity means that a multisectorial intervention program must be considered in order to decrease the problem of overweight among secondary girls. Such program should include dietary intervention to modify food habits, nutrition education through mass media, introducing information on prevention and control obesity in school curriculum, and allocating sufficient time in the school schedule for exercise activities.

This study examined the actual condition of middle school students' dining out based on the data of the 2016 youth food behavior inquiry data of the Korea Rural Economic Institute. The eating out behavior of 278 middle school students' according to gender, average eating-out cost per person, average monthly eating out cost per person, weekly frequency of breakfast, and dietary information source were calculated into a chi-square value by cross analysis. The main results of this study are as follows. First, in middle school students' eating-out status, most students answered 'eating out', and the highest frequency of eating out was 1~3 times a week. The reason for eating out was 'to enjoy delicious food', and 'costly price' was the most common reason for not eating out. Food taste was the most common standard for selecting eating out, and a restaurant was the most common place to eat out. The main restaurant was the 'snack bar (kimbap specialized store)'. Second, there was no significant difference in all items of eating-out status according to the gender. A significant difference in eating out frequency was observed according to average eating-out cost per once (p< .001), standard for selecting eating out (p< .001), main eating out places (p< .001), and main restaurants (p< .01). There was a significant difference in the frequency of eating out (p< .001) in the eating-out status according to average eating out cost per month. Third, the eating-out status according to the breakfast frequency of middle school students had a significant difference in the reason for eating out (p< .001). The eating-out status according to the dietary information source of middle school students had a significant difference in eating out or not (p< .05) and the frequency of eating out (p< .05). These results highlight the importance of school diet education so that middle school students can achieve healthy eating habits and plan to increase their interest and utilization of school dietary education.

This study aims to find out how the nutrition and eating habit education that Korean adolescents receive at school actually affects and affects their dietary culture. he subject and method of this study was a secondary analysis study using the data from the 18th Korea Youth Risk Behavior Survey(2022). Statistical significance was confirmed using the SPSS program as the frequency of breakfast, reason for skipping breakfast, fruit, high-caffeinated beverage, sweet beverage, fast food, vegetable, milk, water, and late-night snack intake frequency as variables. There was a significant difference in breakfast, fast food, and late-night snacks between the group that received nutrition and eating habits education at school and the group that did not(p<.001). Regarding breakfast consumption, the group that received education showed a higher proportion of students eating breakfast for seven days or more, whereas the group that did not receive education showed a higher proportion of students who did not eat breakfast at all. The group that did not receive education showed a higher proportion of students who did not drink milk, and a higher proportion of students who drank less than one cup of water per day. This study can serve as a foundation for further studies to improve nutritional and dietary education, breakfast consumption, and beverage intake in schools. It was hoped that this study will contribute to developing more effective nutritional and dietary education strategies in schools.

This study looked into the obesity status, recognition of obesity, attitude towards obesity, eating and exercise habits, and lifestyles of Korean (n=101) and Japanese (n=123) female college students. All students were 21-years-of age, with an average height of 161 cm and the average weight of 54 kg. Korean female students responded that obesity complicated friendships, and hindered study and exercise. Japanese students did not express these opinions. Both Korean and Japanese students tended to over-consume their favorite food. Korean students ate breakfast about 24.8% everyday, while 48% of Japanese students did; both regularly ate dinner. Snack preference was mainly biscuits. The factor most influencing eating habits were TV advertisement for Korean students (57.4%) and parents for Japanese students (47.2%). Once-weekly exercise was done regularly by 34.7% of Korean students but only 20.3% of Japanese students. The main reason for Korean students to exercise was weight reduction (53.5%), while 78.2% did not exercise because it was tiring. Korean and Japanese students had similar life styles, although stress relief in Korean students was sought through conversations with friends and by reading books or listening to music for Japanese students.

The purpose of this study was to evaluate the current dietary habits, health related behaviors, nutrition knowledge and body indices, and to investigate the changes in nutrition knowledge for designing and monitoring nutrition education program among preschool children. The subjects were 1,200 preschool children, aged $4{\sim}6$ years. A measurement of the height and weight was conducted. The general home environment, the dietary habit of children and nutrition knowledge were collected using a questionnaire that included information about family income, parent's education and occupations. Using the PIBW, 14.6% of the preschool children were under weight, 54.4% were normal, and 31.0% were overweight or obese. We regarded to food habit score, the highest score was in the regularity of breakfast, while the lowest score was in consumption of yellow-green vegetables such as spinach and carrots. Result in food behavior showed that 69.1% of preschool children had a unbalanced diet, and their favorite snack was fast food like pizza and hamburger then followed soft drink and fried foods (chicken of potato). After nutrition education, there was somewhat improvement in the nutrition knowledge score of preschool children from $7.7{\pm}1.7$ point to $8.9{\pm}1.5$ point. These results suggest that nutrition education help preschool children change their nutrition knowledge. Therefore, it would be needed that new appropriate nutrition education to improve dietary habits and health status.

This study was to investigate the behavior related to health, food habits, food consumption pattern and nutrient intakes of female students who residing in dormitory(self cooking) according to BMI(Body Mass Index). This study was carried out by questionnaired on June, 2000. Three hundred nine students were answered. The results were as follows: 1. The means of height, weight and BMI were 162.37$\pm$4.36cm, 52.48$\pm$5.54kg and 19.89$\pm$1.89. Under 20 of BMI among students were 53.1% and 20-25 of BMI were 46.9% of students. 2. In the self recognition of body shape, 63.4% of under weight subjects answered that their weight were normal. 73.1% of normal weight regard themselves more obese than their actual body shape normally shows. 51.2% of under weight subjects had attempted to control their weight. This results suggest that their weight control attempts were unnecessary. 3. 81.4% of subjects were answered irregular meals regardless BMI. 89.6% of subjects skipped breakfast. The main reasons were due to lack of time or not to eat proper food. Under weight subjects had less snack than normal weight subjects did(p '||'&'||'lt; 0.05). Normal weight subjects had more bun and cake than under weight subjects(p '||'&'||'gt; 0.05). 4. The consumption of vegetables and fruits were low regardless BMI. Mean energy, protein, Fe, Vit A, B$_1$, B$_2$, niacin, Vit C were above 75% of RDA, except calcium, in subjects. This study suggest that a comprehensive nutrition education program is need for college student in dormitory to improve their eating habits about skipping meal and breakfast and to increase the consumption of vegetables and fruits.

This study intended to compare dietary and snack habits of primary students in the schools providing and non-providing lunch to clarify the correlation between those conditions and the occurrence of dental caries. Furthermore, this study also focused on evaluating educational effects by providing children with nutritional education program. 1. As a result of dietary habit analysis, it was found that children from the school providing lunch were better in terms of breakfast regularity, eating speed. optimum amount of intake, and meal time regularity than those from the school non-providing lunch. In particular, it was noted that children from the school providing lunch took a little more meat, fish, seaweed and milk or dairy products than those from school non-providing lunch. Thus, it could be assumed hat children provided with lunch have more reasonable dietary habit than those without lunch program. In general, it was found that there was a slight positive change in children's dietary habit after nutritional instruction than before, suggesting that the nutritional education had effects on improving their dietary habit. 2. It was found that primary students often took snacks causing dental caries such as caramel, chocolate, sweets and biscuits, and children from the school providing lunch were more willing to reduce those snacks upon recognizing the causes of dental caries than those from the school non-providing lunch. For the children who chewed gum with physical cleansing effects, it was shown that the highest frequency wat twice or three times a week. Moreover, the ratio of children who took snacks following dinner which might affect their dental caries and the ratio of children who selected snacks because of TV commercial were both reduced after nutritional education. Also the consumption of detergent foods like vegetable, fruit, protein. seaweed. milk or dietary products after nutritional education was increased. 3. It was found that children from the school providing lunch took more often all food groups except for food group IV affecting dental caries than those from the school non-providing lunch. The average number of consuming foods which cause dental caries was 5.04 times per person a day, and most of those were rather taken by liquid than solid food. The average eating times of rinsing foods which kill the bacteria on the surface of teeth and prevent from dental caries, was 9.33 for a person a day, which was a little higher than recommended time. Exposed time for dental caries for a person a day was 100.9 min, of which liquid dental caries was 56.2 min and solid dental caries was 44.6 min, suggesting that liquid food had a high potential to cause dental caries.

The purpose of the study was to develop an eating habit checklist for screening elementary school children at high risk of energy overintake. Dietary habits, food intake, anthropometric data were collected from 142 children (80 boys and 62 girls) in the 4th to 6th grades of elementary schools. Energy intake, fat intake, and percentage of Estimated Energy Requirement (%EER) were used as indices to detect the risk of energy overintake of the children. Pearson correlation coefficients were calculated between dietary habit scores and energy overintake indices in order to select questions included in the checklist. TV watching during the meal, meal speed, meal amount, overintake frequency, eatingout frequency, snack frequency, frequency of eating Ramyun or fast foods showed significant correlations with energy overintake indices. Stepwise regression analysis was performed to give each item a different weight by prediction strength. To determine the cut-off point of the test score, sensitivity, specificity, and positive predictive values were calculated. The 7-item checklist with test results from 0 to 13 points was developed, and those with equal or higher than 5 points were diagnosed as a risk group of energy overintake. Among our subjects 13.4% was diagnosed as the risk group. Mean energy intake of the subjects in the risk group and the normal group were 2,650 kcal and 1,640 kcal, respectively. However, there were no significant differences of Index of Nutritional Quality (INQ) of the other nutrients except eating fiber between the risk group and the normal group. This checklist will provide a useful screening tool to identify children at high risk of energy overintake.

Purpose: This study examined the relationship among the use of food-related content (FRC), dietary behaviors, and dietary self-efficacy to demonstrate the need for nutrition education to help adolescents build healthy eating habits and provide evidence for developing nutrition education programs for adolescents. Methods: Three hundred and eighty-one high school students in Seoul and Gyeonggi areas participated in the study. The subjects were divided into three groups (low, medium, and high) according to the level of use of the FRC, and their general characteristics, dietary behaviors, and dietary self-efficacy were analyzed. Correlation analysis was performed between FRC usage, dietary behaviors, and dietary self-efficacy, and the mediating effects of dietary self-efficacy on the relationship between the level of the use of FRC and dietary behaviors were estimated. Results: A higher level of FRC usage was associated with an increased daily cost of eating out and snacking, but no difference was observed in the BMI range. The subjects in a group with a high level of FRC usage ate convenience store or instant foods instead of homemade meals (p = 0.033), had a late-night meal or snack (p = 0.024), and turned to emotional eating under stress (p < 0.001) more than those in the low level group. In addition, the high level group checked the nutrition facts label more carefully when purchasing processed foods (p = 0.016) and exercised at least 30 minutes daily, not considering physical education classes (p = 0.057). The higher level of FRC use, the lower the dietary self-efficacy, whereby the subscales 'environmental stimulus control efficacy' and 'affective factor control efficacy' showed complete mediating effects. Conclusion: Given that FRC has been increased recently, adolescents are in need of support to help them control and enhance their dietary self-efficacy as well as develop healthy dietary behaviors through proper nutrition education programs.
