The prevalence of obesity in children has steadily risen during recent years in developed countries. Child obesity has become a major concern to health providers since it has grown to epidemic proportions over the past few decades. This study was conducted to investigate the biochemical status, dietary habits and life styles according to the obesity degree among obese children residing in the Gyungbuk area. The subjects were 148 elementary school students (boy 103, girl 45) and classified as mildly obese (n = 56), moderately obese (n = 61) and severely obese (n = 31) by the obesity index. The average body weight and height increased significantly according to the obesity degree (p < 0.05, p < 0.001). Serum cholesterol concentration came under the normal level in all groups. Serum AST activity increased according to the obesity degree but it was not significant. Serum ALT activity increased according to the obesity degree (p < 0.05). Dietary habit score was lower significantly according to the obesity degree (p < 0.01). Life style of the subjects was significantly different for the level of 'healthy state (p < 0.05)', 'body perception (p < 0.01)', 'watching TV and video (p < 0.05)', 'normal sleeping hour (p < 0.05)' and 'degree of stress (p < 0.05)' according to the obesity degree. A positive relationship between obesity index and blood pressure, ALT has been shown in the subjects. Obesity index and dietary habit scores were negatively associated. Therefore, these results suggest that a practical nutrition-exercise education program for the prevention of child obesity should be provided to elementary school children.

Purpose: This study was conducted to examine the status of dietary behavior and its association with study-related factors in middle school students. Methods: Study-related factors, dietary habit score and dietary behaviors were surveyed by questionnaire and then analyzed. A total of 580 students in some middle schools in Gyeonggi-do participated in this study. Collected data were analyzed using SPSS for windows Ver. 22.0. Results: 71.3% of the subjects slept for 6 ~ 8 hours, and the studying time outside of school was the highest (2 ~ 4 hours). The highest score for stress from studying by private lessons or academies was 'seldom stressed', with higher stress being observed in male students than female students. The average dietary habit score was 3.69 in male students and 3.62 in female students. The highest average time for meal eating was 10 ~ 20 minutes, with shorter times being observed for male students than female students. Eating meals was regular in most students and the highest number of snack eating was 1 ~ 2 times a day. For dietary behaviors by study-related factors, students with more than 2 hours of studying time outside of school showed higher dietary habit scores than those with less than 2 hours, who showed significantly higher rates of eating 2 meals a day. As the sleeping hours and daily average studying hours increased, the rate of regular meal eating increased significantly. Conclusion: The students showed good, above average dietary behaviors, but gender differences in study-related factors and dietary behaviors. Moreover, the sleeping hours and the studying time outside of school were correlated with dietary habit scores and dietary behaviors. Thus, continuous and systematic education for proper dietary behavior is needed along with greater interest in students with problems of study-related factors, particularly those due to study burden.

This study was carried out to examine the effects of nutrition education program developed by Jincheon Public Health Center on preschool children's nutrition knowledge and dietary habits and the parents' dietary attitudes. The subjects of this study were five- and six-year-old children as well as their parents. A 5-week nutrition education program was implemented to 104 children in five day care centers, and 107 children in three day care centers were investigated as a control group. Activity tools designed for each lesson such as puzzles, food magnets, story, songs, Pierrot costume, and balls were used. Nutrition knowledge and dietary habits of children and dietary attitudes of parents were evaluated before and after education. Mean nutrition knowledge score in the education group was significantly higher than that in the control group after education (p < 0.001). Mean dietary habit score of three questions (three meals a day, eating at fixed time, eating breakfast) in the education group was also significantly higher than that in the control group after education (p < 0.01). In addition, parents in the education group showed significantly higher mean dietary attitude score than those in the control group even though they did not receive education (p < 0.001). Our nutrition education program was found to be effective in improving nutrition knowledge and dietary habits in preschool children as well as improving dietary attitudes in their parents.

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.

The purpose of this study was to compare dietary self-efficacy for sodium intake reduction and dietary behaviors by eating areas. Subjects (797 males and 767 females) were classified according to perceived dietary habit levels related to sodium intake (lowest: ${\leq}10$ (n=434), low: $11{\sim}{\leq}13$ (n=471), high: $14{\sim}{\leq}15$ (n=360), highest: $16{\leq}$ (n=299)) using an online survey with a sample that was geographically representative of the population. The highest group was significantly younger and had a higher student proportion than the lowest group. Dining contexts regarding home led to a significantly higher sodium intake in the highest group, but it was eating out for the lowest group. The highest group had a significantly lower intention to reduce sodium intake compared to the lowest group. In the home cooked meals, the highest group displayed a significantly lower cooking frequency, less effort with respect to a low sodium diet and cooking habits related to sodium intake as compared to the lowest group. Also, regarding eating out and food service, the highest group exhibited significantly lower efforts and dietary behaviors to reduce sodium intake than the lowest group. The dietary score for sodium reduction behavior in the highest group was significantly lower compared to the lowest group, for home cooked meals, eating out, as well as food service. Thus, dietary guidelines and nutrition education for the reduction of sodium intake by eating areas need to be developed and provided.

The purpose of this study was to evaluate the nutrient and food intake status in underweight female college students living in Seoul. 126 underweight(BMI<20) and 74 normal weight (20$\leq$BMI<25) students were asked for their daily food intake and eating habits by using 3-day food records and questionnaire. We analyzed the amounts of the nutrient intakes and food groups as the subjects. The mean of height and weight were 162.1cm and 49.0kg in underweight and 160.6cm and 54.9kg in normal weight subjects. The mean energy, iron, and vitamin A intakes among the students were smaller than RDA for Koreans. The mean calcium(p<0.01), sodium(p<0.05), and vitamin B$_2$(p<0.05) intakes in underweight subjects were significantly higher than those in normal weight subjects. Total food intakes of underweight and normal weight students were 1235.8g and 1078.1g, respectively. The mean of the pulse group in the underweight was significantly higher than that in normal group(p<0.01) Frequently consumed food or dish items of the subjects were Kimchi, cooked rice, and milk. In the relation between BMI and dietary factors, the BMI was found to have a significant negative correlation with calcium intake(p<0.05), pulse intake(p<0.01) and eating habit score(p<0.01) Eating habit scores about quantity of food and lipid intake showed a significant difference between underweight and normal students.

The purpose of this study was to provide basic informations for educating juveniles on desirable body image recognition by examining their body image recognition and comparing and finding problems according to gender and body mass index (BMI) in middle school students. The average age of the subjects was 15, their average height was 162.5 cm, their average weight was 53.5 kg, and their average BMI was $20.1\;kg/m^2$. Male students wanted to gain weight and female students wanted to lose weight. As for body shape, female students thought that they were fat more often than male students. Also the more overweight the students were, the higher their concerns and experiences toward weight control. Among weight control methods, exercise scored highest in all BMI groups. Over 80% of the respondents answered that their weight control effort were not systematic such as via professional counseling. As for the frequency of eating breakfast and dinner in female students, the more a student was overweight, the lower their frequency of eating breakfast and dinner. Many respondents answered that a typical meal time was '10~20 minutes'. The average eating habit score for all subjects was 38.0. The eating habit scores of male students were significantly higher than those of female students, and there were no significant differences among BMI groups. Eating habit score of 'I have more than two meals with rice everyday' in female overweight group was significantly higher than those of other two groups. These results indicate that the female students' degree of preference for a slim body shape were higher than those of male students. In addition, weight control by students is not systematic through professional counseling; instead they attempt to control their weight by themselves such as a meal skip, which lead to potential danger that they may lose weight carelessly. Therefore, correct body image recognition is greatly needed, and families and schools should make ceaseless efforts to help students properly control their weight and have correct eating attitudes.

The purpose of this study was to analysis of food adaptation and dietary behavior of marriage migrant women in according to their acculturation type, and find out their relationship. The survey was conducted by well-trained researchers using questionnaires translated into English, Chinese and Vietnamese. Food adaptional score was the highest in the assimilation type, and the separation type was the lowest. Dietary behavioral score in daily intake of milk and dairy foods was the highest in the assimilation type. There were positive correlations occurred between food adaptional score and dietary behavioral score, and also, between food adaptional score and assimilation score. Analysis of structural equation models shows that only assimilation affects food adaptational score, and food adaptational score affects the improvement of dietary behavior. In conclusion, marriage migrant women's positive attitude of new cultures, assimilation, might help them not only adapt to new cultures, but food adaptation and right dietary behaviors.
