This study was designed to develop, implement and evaluate a nutrition education program for elementary school children. Subjects consisted of 47 children in the 6th grade in Seoul, Korea. They received five sessions of nutrition education from June to July, 1999. Topics for nutrition education included function of nutrients, food sources of nutrients, balanced diet, meal planning, and adequate energy intake. Each session lasted 40 minutes. To evaluate program effectiveness, one group pretest-posttest design was used. Subjects were given a pretest and a posttest on nutrition knowledge, eating attitudes, eating behavior, and dietary intake. All data were statistically analyzed mainly using the paired t-test and $\chi$$^2$-test. There was a significant difference between pretest and posttest score on nutrition knowledge(p<0.001), subscales of nutrition knowledge including food sources of nutrients, function of nutrients, and balanced diet(p<0.001). These changes in nutrition knowledge were also shown both in boys(p<0.001) and in girls(p<0.001). Eating attitudes, subscales of eating attitudes, and eating behavior were not significantly changed after nutrition education, although some changes were observed in these variables. Dietary intakes were not significantly were not significantly changed after nutrition education for all subjects ; however, different patterns in dietary intakes were observed when examined by sex. There was an increase in nutrient intakes among boys, while there was a significant decrease in nutrient intakes among girls after program implementation. Especially, it was noted that girls had diets deficient in iron, calcium, and vitamin A, even after nutrition education. It was concluded that a five-week nutrition education program can improve nutrition knowledge or some dietary intake, but this might not be enough to induce changes in food attitudes, eating behavior or dietary intakes. It might be necessary to incorporate diverse approaches, targeting sub-groups of children, and follow-up in nutrition education for elementary school children.

The trial was conducted to assess the impact of consulting through telephone on body weight reduction among 18 obese adult women. The degree of obesity, food intake pattern, and life style were examined through phone calls. Subjects visited our clinic and their body fat percentages were measured using impedance fat meter (model SIF-891), and were recommended and recorded to have a low calory diet with changes in the food habit and behavior. The study results are as follows: 1. There is a positive relationship between food habit, lifestyle, obese degree, and fat percentage. 2. 8-10kg and 5kg reductions in the body weight were observed among 14 subjects and 2 subjects, respectively. However, 2 subjects maintained their body weights. 3. The body reduction curve looked like a stairway (type) with low slope and was related with food intake amount. 4. It was possible to have the adequate protein intake only through the vegetable diet. 5. 15 out of 18 subjects were on the prescribed low calory diets for 3 days. Therefore, there is a time limitation to follow the diet treatment. 6. A body weight reduction altered dietary intake of foods which were rich in sweet taste, and the favorite foods were chocolate and candy.

By improving body composition, such as fat, lean body mass and total body weight, an exercise program can be an effective treatment of obesity. The effects of exercise on obesity have been confirmed via various approaches such as type, intensity, duration, frequency, and combination with diet. Combined exercise and diet is the most efficient strategy for weight loss, and exercise alone could improve metabolism irrespective of weight loss. In addition, physical activity, including exercise, is emphasized to avoid a 'yo-yo' phenomenon. Exercise increases lipolysis stimulated by such factors as catecholamine, growth hormone (GH), and hormone sensitive lipase (HSL). Moreover, changes in insulin and cortisol through exercise affect adipose tissue, which is known as not only an energy storage locale, but also as an endocrine organ. Adipocytokines secreted by adipose tissue respond to signals that modulate metabolism and inflammation. Exercise has generally shown positive effects on adipocytokines, and these effects increase in conjunction with a hypocaloric diet. However, a long duration and a high intensity of exercise could induce an inflammatory response. This review summarizes the effects of exercise on obesity treatment, which contributes to the exercise and nutritional fields, particularly of community nutritionists.

Purpose: The purpose of this study was to examine the effect of diet education on nutritional status in patients with gastrectomy. Method: This study was designed with a nonequivalent control group pre-post test. Ten patients were assigned to the experimental group and fifteen were assigned to the control group. The experiemental group was given the diet education by multimedia including complications after gastrectomy, the way of how to prevent these complications, precautions that patients need to be follow, and food that patients should and shouldn't eat. Data were analysed with a $x^2$-test(Fisher' exact test) and Independent sample t-test, Repeated measures ANOVA, using SPSS WIN 15.0 program. Results: There were significant differences in weight, daily caloric intake, knowledge score between experimental and control group. However, there was a no significant difference in blood profile(albumin, total protein, hemoglobin) between two groups. Conclusion: This study shows that the diet education with multimedia could improve nutritional status for the patients who had gastrectomy.

This study aims to identify the dietary patterns relevant to obesity of Korean women among low income classes. Adults 20-64 years were used as study subjects from the data of 2005 Korea National Health and Nutrition Examination Survey. We compared obese and normal-weight women in terms of their nutrients intake, diet quality and food patterns. Diet quality was assessed by using the Nutritional Adequacy Ratio (NAR) and Index of Nutritional Quality (INQ). Our results showed higher prevalence of obesity among lower socioeconomic status women. In men, there were no significant associations with socioeconomic status and prevalence of obesity. Higher risk of nutritional inadequacy was observed among obese women compared to normal weight women. Obese women showed significantly lower INQ for nutrients such as Ca, Fe, Vitamin A, Thiamin, Riboflavin and Vitamin C compared to other women. They consumed significantly higher amount of rice (p < 0.05) and lower amount of vegetables (p < 0.01). By contrast, obese men from low income classes showed higher intake of those nutrients. Obese men also consumed significantly higher amount of meats than normal weight men. Therefore, this study suggests that gender-specific approaches based on economic situation should be considered in developing the intervention program for managing obesity for low income classes.

Objective : As part of the Korean Medicine Official Development Assistance(ODA) and Public Health Project, we implemented a obesity management program(OMP) using Korean medicine in Uzbekistan and its follow-up study was conducted to evaluate the effectiveness of the program. Method : We recruited the participants of whose Body Mass Index(BMI) were over $25kg/m^2$ and who agreed to participate in the program at the South Korea-Uzbekistan Friendship Korean Medical Hospital in Uzbekistan. The program consisted of auricular acupuncture, functional food, and education program on diet and exercise. It was provided once a week during 7-week period. Anthropometric measurements and blood test measuring total cholesterol, triglyceride, and glucose were performed at the baseline, the end of the program, and 10-month follow-up. At the end of the program and the follow-up, survey on satisfaction and self-evaluation of the effectiveness of the program was additionally conducted. Results : 43 out of 78 participants completed the program and were included in the analysis. The analysis of the main outcomes showed that there were significant decreases in anthropometric measurements such as body weight, waist circumference, body mass index (BMI) and body fat content as well as blood test including triglycerides, total cholesterol and blood glucose levels. In the follow-up study, 24 subjects participated and 19 subjects (79.1%) reported that they succeeded in weight control. Furthermore, many participants reported that they maintained healthy lifestyles like healthy diet and regular exercise. The satisfaction with the program was also relatively high, and the education program was selected as the most motivating intervention for weight control. The outcomes such as body weight, BMI, body fat content, and blood glucose level were maintained to be at the decreased level; however, waist circumference, total cholesterol and triglycerides levels either returned back to the baseline level or were elevated to the level higher than the baseline. Conclusion : This study suggests that the OMP using Korean medicine may contribute to weight control of obese population in Uzbekistan. It is meaningful in that the study shows the possibility of implementing health promotion programs using Korean medicine in other countries with different cultures. In the future, more efforts to evaluate the effectiveness of the programs using rigorous methodologies and utilize the effective programs in ODA project will be needed.

The increased number of elderly in Korea presents great challenges for community nutrition programs. Strategies to enhance elderly nutrition are needed, as well as dietary advice that are reality-based and tailored to the need of the elderly. The purpose of this study was to evaluate the overall effectiveness of an elderly nutrition improvement program(ENIP), by assessing changes in nutrition knowledge, attitudes, and behavior after program completion. ENIP was conducted in Suwon for 4 months in 1998 at 5 centers for the elderly. The program provided individual nutrition counseling and brief biweekly group education sessions. To stimulate participation and motivation, the elderly in two centers were served free milk packs(200ml) three time a week during the program(milk＋education group), and the elderly in 3 other centers were served yoghurt on the program day(education group). Altogether, 102 subjects finished the program(milk＋education group 67 ; education group 35). Data about nutrition knowledge, dietary attitudes, diet records(24 hour recall) and dietary habit was collected before(baseline) and after the program(follow-up). The Drop-out rate for the milk＋education group(2.9%) was significantly lower than that for the education group(30.0%)(p<.001). The Nutrition Knowledge fo females milk＋education group increased significantly after the program, but no significant differences were observed in other groups. Over 60% of all the elderly showed positive responses to the healthy eating attitudes. Energy, protein, vitamin A, riboflavin, Calcium and Potassium intakes improved in the male milk＋education group. The Vitamin C intake improved in the male education group. Energy and vitamin A intakes improved in the female milk＋education group and energy, vitamin A, thiamin, riboflavin, niacin, Ca nad P in the female education group. A stepwise multiple regression analysis was performed to examine the effects of food intake changes on overall nutrient quality. For all elderly, the fish intake explained 12.6% of the variance, followed by candy intake and vegetable intake(model $R^2$=19.6%). Dietary habits such as meal time regularity and salty food reduction were markedly improved in both groups. Sixty-one percent of the milk＋education subjects stated their participation was voluntary and active, while 51% of education subjects did. Sixty four percent of the subjects stated their interest on diet increased remarkably through program participation. Considering the results, it is conjectured that ENIP had a great impact on nutrient intake, dietary attitudes and habits. Milk supplement showed no direct effects on elderly nutrition improvement, but it encouraged the program by reducing drop-out rates and inducing voluntary participation. Therefore milk supplement could enhance the community nutrition education program. Moreover it is strongly suggested that the ENIP be expanded to other communities.

The purpose of this study is to develop a software program for nutritional counseling by assessment of nutrients intake status and health degree by using semi-quantitative frequency food intake method and the questionnaire of Cornell Medical Index(CMI) and farmers' syndrome. This program is composed with three parts, nutrients intake, health status with body complaints, and nutrition counseling contents for diet therapy of each body condition states. First, nutrient intakes with percentage of Korean Recommended Dietary Allowances, and quantities of other nutrients intake were calculated and presented in an out-put screen. Second, the different body complaints(farmers' syndrome, anemia, hypertension, gastrointestinal problem, and cardiovascular complaints) were divided 3 groups of health status as normal. suspected and ailment. The contents of nutritional counseling with recommended food kinds. intake quantities. and recommended preparation methods were shown by button click of each health state of body complaints. And also this program could serve several times for one person to compare nutrition education and counseling effect by use of pre and post presentation results. This programs would be effect to home extension workers of rural development administration for farmers' nutrition counseling.

This study was conducted to evaluate the effects of constitutional diets in comparison with general low calorie diets in obese women. The subjects were 52 adult obese women that participated in a calorie restriction diet program (control group, n=16) or a constitutional diet program (experimental group, n=36) for 8 weeks. The subjects in the experimental group were classified as negative (Yin) or positive (Yang) constitution. The obesity management program focused on the calorie restriction diet (300~400 kcal reduction per day) for the control group, whereas, for a constitutional diet without calorie restrictions was allowed for the experimental group. Daily intakes of nutrient and food were assessed using a 24 hr recall method. Body measurements and blood biochemical parameters were measured at baseline and after 8 weeks. After the intervention, weight, body fat, BMI, waist circumference and hip circumference decreased significantly in both the control and experimental group. Energy intake increased from 1,679.6 kcal to 1,810.6 kcal along with significant increase in protein, carbohydrate, fiber, calcium, phosphorus, iron, zinc, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin and vitamin C in the experimental group. Calcium intake increased from 54.0% to 72.4% of DRI in the experimental group. Hemoglobin concentrations were significantly decreased in the control group, but were increased in the experimental group. In addition, blood glucose, serum total cholesterol and triglyceride were significantly decreased in the experimental group. In conclusion, consumption of a constitutional diet without calorie restrictions for 8 weeks was effective for weight reduction with improvement of blood glucose, serum cholesterol and triglyceride.
