The purpose of this study was to investigate the patterns of fast food intake in residential areas and its relation to eating habits among 551 6th grade students (286 male students and 265 female students) from elementary schools located in Gangnam-gu, Dongjak-gu and Seongbuk-gu, Seoul. The results of this study were as follows. 1) There were significant differences in the preference for fast food among districts (p<0.05) and children from Seongbuk-gu showed a greater preference for fast food than those from Gangnam-gu and Dongjak-gu. In terms of preferences for particular types of fast food, children from Seongbuk-gu liked hamburgers more than those from Gangnam-gu and Dongjak-gu so that there were significant differences among districts (p<0.05). With regards to the frequency of intake of the various types of fast food, there were differences in hamburger, pizza and chicken among three districts (p<0.05) and children from Seongbuk-gu ate fast food 1 to significant 2 times more often than those from Gangnam-gu and Dongjak-gu. 2) There were significant differences in the regularity of mealtimes between districts (p<0.05), with children from Seongbuk-gu showing more irregularity in their mealtimes than those from Gangnam-gu and Dongjak-gu. There were significant differences in the frequency of snack intake (p<0.05), and children from Seongbuk-gu tended to take a snack 1 to 2 times more often than those from Gangnam-gu and Dongjak-gu. 3) In the frequency of fast food intake in accordance with obesity, there were significant differences between the obesity index (p<0.05). In particular, children who were underweight had a tendency to eat more fast food. There were significant differences between the frequency of fast food intake depending on children's pocket money (p<0.05), and children who took fast food more than twice a week tended to have more pocket money. According to these results, we report there are partly different trends in the consumption of fast food and food habits among the districts in Seoul. Therefore we suggest that different interventions be implemented within the different districts to reduce reliance on fast food restaurants and to address the perceptions of healthy eating as well as time and convenience barriers.

This study was carried out to determine the blood glucose responses to 10 kinds of typical Korean domestic meals, 9 kinds of eating out meals and 5 kinds of diabetic meals recommended by hospitals. The levels of blood glucose were measured at 15, 30, 60, 90 and 120 minutes after taking 24 kinds of meals(500$\pm$10㎉) and 50g of glucose to healthy volunteers. The blood glucose response areas and glycemic index(GI) were calculated. There was no invariable tendency of blood glucose responses among diabetic meals, general domestic meals and eating out meals. As the units of grain groups were increased, the GI of meals was increase. When the units of grain groups are same, the side dishes also affected the blood glucose responses, however, it is yet unknown what kinds of food materials of side dishes affected the blood glucose responses. Noodles (Chinese style, kalgugsu(Korean home made) and ramen) lowered blood glucose responses compared to steamed rice. Mixing barley and brown rice with polished rich also lowered blood glucose responses, especially when the mixing ratio of them was over the 15%. The lowering efficiency of barely was greater than brown rice. More than three grain units of rice increased the blood glucose response. The GI was significantly correlated with left area ratio(LAR), right area ratio(RAR) and blood glucose levels at 15, 30, 60, 90 minutes. The RAR and blood glucose levels at 30 minutes profoundly affected the GI.

Purpose: The purpose of the study was to investigate whether adherence to the Korea Healthy Eating Index (KHEI) was associated with metabolic syndrome and risk markers. Methods: The participants included 8,345 adults, aged 20-59 years, who took part in the 7th Korea National Health and Nutrition Examination Survey (KNHANES). The data were analyzed using a complex-sample t-test, the Rao Scott χ²-test, and logistic regression analysis on the SPSS v. 26.0 software. The participants were divided into four groups by quartiles of KHEI scores. Results: The average KHEI score was 61.06 points out of 100, and the women's score (62.50 points) was significantly higher than that of men (59.63 points). The KHEI quartiles status showed significant differences by age (p < 0.001), household income (p < 0.001), smoking status (p < 0.001), and food security. Specifically, the KHEI quartiles in the men showed significant differences in education (p < 0.001) and economic activity (p < 0.001) whereas those of women showed significant differences in alcohol-consumption (p < 0.001), depression (p < 0.01) and eating-out (p < 0.001). As the KHEI scores increased, the proportion of subjects with an energy intake below the estimated energy requirement (EER) was lower, and significantly better levels of intake were observed for carbohydrate, protein, vitamin C, calcium, vitamin B₁, vitamin B₂, and niacin. The incidence of the metabolic syndrome risk factors, hypertriglyceridemia and hyperglycemia for men and hypertension, and hyperglycemia for women showed significant differences. The KHEI scores were inversely associated with abdominal obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol, hyperglycemia, hypertension, and metabolic syndrome. Conclusion: Based on these results, we conclude that higher adherence to the KHEI was associated with lower metabolic syndrome risk factors and incidence of the metabolic syndrome.

This study was to investigate the children's understanding level of nutritional knowledge and the degree of knowledge application into the actual living not only in the with-lunch school but also in the without lunch school. Having expected their obtaining of nutritional knowledge and practical applicating, we compared the with-lunch school children's understanding level of nutritional knowledge, dietary attitude, and completeness of diet life with those of without-lunch school children. In addition to this, we surveyed healthiness, Physical condition, and BMI (Body Mass Index) and compared these factors. The results are as follows. 1. Almost all of the children were standard in physical condition, however they recognized themselves fatty than normal. Mealtime consumption(p＜0.05), BMI(p＜0.05), and diet attitude points(p＜0.001) showed significant difference in the children who regarded the themselves healthy. 2. High correlation was observed between parent's physical shape and mealtime consumption (p＜0.05), quantity of eating food (p＜0.001), children's BMI(p＜0.001) and diet attitude(p＜0.05) respectively. 3. The points of itemised nutritional knowledge test was different in accordance with the children's year grade (p＜0.05), children's understanding level of health and physical condition(p＜0.05), parent's physical shape (p＜0.05), and mother's education level(p＜0.05) respectively. The points of nutritional knowledge test in both schools showed no difference except the item of vitamin.

This study was intended to collect the baseline information on dietary behavior of adults to develop nutrition education program in the context of health promotion at community level. Nutrients intake of 135 housewives were assessed by 24 hour recall methods. Also food habits, nutrition knowledge and attitude were investigated by self-administered questionnaires. Our results indicated dietary intake of calcium and vitamin $B_2$ were insufficient when they were compared to Korean recommended dietary allowances(RDA). Among five food groups, intakes of milk and dairy product was inadequate as compared to the recommended amount. When we compared the fatness indices to self-evaluated meal problems, overeating and speedy eating were significantly related to fatness indices. Fatness indices such as relative body weight(RBW) and body mass index(BMI) were significantly higher in the subjects who self-evaluated their unsound food behavior as overeating. However, there were no significant differences of food habit score and nutrition knowledge among groups classified by fatness or meal problem. Body fat ratio, frequencies of night snack and skipping meal significantly increased with age. Food habit score was positively related to health-concerned attitude and active attitude toward change. We concluded that nutrition education program for housewives should include detailed strategies to modify unsound food behaviors for healthy weight.

Purpose： The purpose of this study was to investigate the actual conditions of obesity, and the factors related to children's obesity. Method： The subjects were 568 students (5th, 6th grades) of ten elementary schools in a small city of about 350,000. Subjects self-reported after being instructed by researchers to identify health habits and attitudes toward obesity. The Rohrer index was calculated by using annual physical examinations preformed by the schools. Result： 17.5％ of the subjects were under weight, 22.2％ were overweight, and 60.3％ were normal. In girls, the under weight group was much larger, in boys the overweight group was larger. 46.2％ of overweight children had a familial tendency to obesity. 60.6％ of boys and 60％ of girls were on a diet in order to improve their looks or to prevent ridicule from mends. On average, one-third of the subjects misunderstood their own weight level. Subjects spent 3-4hours on weekdays, and over 6hours on the weekend watching TV or using personal computers. The overweight group enjoyed eating meat, fish, beans and vegetables, while the normal group tended to prefer fruit. Conclusion： Health education programs which guide elementary school students to form better health habits, more accurate perceptions of their own body weight, and better attitudes toward obesity and which make students aware of the importance of exercise, a healthy diet, and reducing time spent in front of TVs and computers may help them to keep at their appropriate weight.
