This study is performed to evaluate the effectiveness of a weight management program for overweight and obesity office workers; comparing their changes in the anthropometry, biochemistry, nutrient intakes, and exercise performance before and after the obesity management program. This program was performed on 39 workers, who are overweight or obese, over BMI 23 for 6 months in Jeollabuk-do public institution. As the results of this study suggests, triceps thickness (TT) of male subjects was significantly decreased (P<0.05). Waist circumference (WC), and hip circumference (HC) of the total subjects were significantly decreased after the weight management program (P<0.05). The biochemical result of the Total cholesterol (TC) (P<0.05) and LDL cholesterol (LDL-C) (P<0.01) was significantly decreased in male subjects. The results of abdominal computed tomography (CT) also showed that subcutaneous fat area (SFA) of male subjects was significantly decreased after the weight management program (P<0.01). The nutrient intake's results of female subjects, who took Fe, Vit B2, and niacin, were increased significantly after the weight management program (P<0.05). The nutrition knowledge score of male subjects was significantly increased (P<0.05), and a muscular endurance of the physical test was significantly increased after the obesity management program (P<0.01). At the work place, workers need a systemic health and obesity management program to improve their work efficiency and quality of life. After this study, the program should be developed and supported continuously to maintain positive results from this study.

The purpose of this study was to develop measures for establishing and enforcing legal nutrition labeling for Takju based on results from consumer awareness surveys, statistical model development, and evaluation of nutrients. The statistical model developed with consumer survey results showed that consumers would like to know the nutrients they intake from drinking Takju, as their awareness about Takju was low. Specifically, consumers would like to see information regarding alcohol content, calories, carbohydrates, and saccharides on the label. Structural equations from the research model showed that consumers who had some knowledge of Takju also had positive thoughts of the nutrition fact labels for Takju. Evaluation of nutrients in Takju showed that the starch sources and other ingredients used in Takju fermentation did not influence nutrient facts, and nutrient concentrations also varied among the different Takju. In addition, this research suggests methods for consumers to make reasonable selections and to inform them of the nutrition fact labeling for Takju. Benners and pop-up were manufactured to promote voluntary participation of companies and to provide nutrition facts from Takju. Eventually, a measure was suggested to establish and enforce nutrition labeling, using results from consumer and nutrient surveys of Takju.

The purpose of this study was to examine vegetable & fruit (V/F) intakes, beliefs and self-efficacy regarding V/F consumption, nutrition knowledge and eating behavior of elementary students. A survey was conducted to the 4th graders (n = 234) at two elementary schools in Guri, Kyunggi-do. About one-fourth of subjects were overweight or obese. Subjects had 4.2 servings of V/F a day, consuming 340.2 g of V/F. Girls consumed significantly more amounts of vegetables than boys (p < 0.05). Girls were more favorable regarding V/F consumption (p < 0.01), and believed more strongly on advantages of having V/F such as “good for skin” constipation prevention (p < 0.001) and cancer prevention (p < 0.05). Boys felt more strongly in disadvantages or barriers of eating V/F, including mother's cooking time constraints (p < 0.01), lack of past experience of eating V/F, and family members' disliking of V/F (p < 0.05). Girls felt more confident in eating V/F (p < 0.05) than boys; they also felt more confident in specific items of "eating fruits/salads instead of cookies/chips for snack" and "eating fruit juice/vegetable juice instead of soda"(p < 0.01). Subjects showed low level of nutrition knowledge, especially in items such as balanced meals, recommended servings of V/F and vitamin deficiency. Compared to boys, girls had more desirable eating behavior such as eating adequate amount of meals (p < 0.001), having a variety of foods, eating fruits daily, and having fatty foods less frequently (p < 0.05). Intakes of Ca and K were quite below the recommended level, while the intakes of protein, Na and vitamin A intake were much above the Dietary Reference Intakes (DRI) for 9-11 old children. Nutrient intakes expressed as %DRI was higher in girls for vitamin A (p < 0.01), energy and riboflavin (p < 0.05). High V/F consumption group (${\geq}5$ servings of V/F a day) compared to the counterparts showed higher self-efficacy and had better eating behaviors. Nutrition education for children should focus on increasing consumption of V/F, by helping them to increase self-efficacy for eating V/F and to recognize the benefits and reduce the barriers of eating V/F, especially in boys. It is also needed to provide nutrition information for balanced meals or increasing V/F consumption, and help the children to adopt desirable eating behavior.

This study inrestigated the dietary behavior, nutritional intake, and health status of industrial workers. Two hundred seventy workers(165 men and 105 women) in Masan, who were provided food services were selected as survey subjects. They were given questionnaires on nutrition knowledge, food frequency questionnaires, and blood analysis were conducted through an annual health examination from May to August 1998. The average age of the subjects was $35.7\pm{11.8}$ years, and 80% the of women were in their teens and 20's and 80% of men were in their 30's and 40's. The nutrition knowledge score was higher in women than in men, while food habit score was higher in men than in women. As age increase, the degree of life stress became lower and food habit score was higher in men than in women. As age increases, the degree of life stress became lower and food habit was improved. In women, all nutrient intakes were avove the recommended dietary allowances(RDA), and in men intakes of only vitamin E and calcium were under RDA. Levels of serum total cholesterol, triglyceride, and blood glucose, blood pressure, body mass index were positively related to age. The number of subjects suspected of having chronic disease was the highest for those in their 40's. The results indicate that nutritional status of industrial workers in the present study was fairly good probably due to food services, but their health status should be supervised as their age increases.

This research was performed to investigate the effects of NEP (Nutritional Education Practice) program developed by KHyDDI (Korea Hypertension Diabetes Daegu Initiative) for hypertension and diabetes patients. The subjects were 116 patients (hypertension 70, diabetes 46) who had completed basic education program at the education information center and four-session program was implemented for them. Nutrient intake was analyzed and compared before and after the program by 24-hr recall method and evaluate weight, waist circumference, body fat, blood pressure and eating habits in terms of nutrition knowledge, eating behavior, salty taste assessment. The improved results after the program were observed in weight, waist circumference, body fat ratio, blood pressure, slightly salty taste in salty taste assessment, nutrition knowledge, eating behavior, sodium, energy, carbohydrate and protein intake ratio to total energy (p < 0.001). Therefore, this program is effective in the improvement of weight, waist circumference and eating behavior, and the continued management would lead to the prevention of cardio-cerebrovascular diseases in the community.

Survey the intake of carbonated beverage and the perception of carbonated beverage was conducted with 422 middle school students in Daegu area to clarify attitudes toward carbonated beverages and their consumption in adolescents. Statistical data analysis was done using SPSS version 12.0. Of all subjects, 31.3% preferred carbonated beverage among all beverages consumed, and preference for flavored carbonated beverage was highest (42.2%). Students who liked to drink carbonated beverage spent more money in snacks out of their allowance; frequency of carbonated beverage consumption correlated with amount of allowance (p<0.05). Carbonated beverage was mainly consumed with fast-food (61.5%), and 53.3% of the students purchased the beverages at supermarket. The majority of middle school students (30.4%) drank carbonated beverage more than 3~5 times a week, which was high frequency of carbonated beverage consumption. Preference and consumption frequency beverages differed significantly with knowledge level (p<0.01). Of the subjects, 73.2% drank carbonated beverage without checking nutrient contents, and those with low knowledge level of carbonated beverage neither read the label on nutrients nor were interested in nutrition education (p<0.05). The results underscore the need to provide systematic nutrition education at home and in school to prevent excessive intake of carbonated beverage and to help adolescents choose healthy beverage during a time in life when growth is especially prominent.

The purpose of this study was to evaluate the effectiveness of an intervention program using dietary consult and physical exercise conducted by public health center in Chuncheon city for obese adults. This study used a pretest-posttest design. The subjects were 58 out of 90 obese adults with body mass index (BMI) greater than $25kg/m^2$ who completed all education sessions for 8 weeks. Data on dietary habits, dietary behaviors, nutritional knowledge, anthropometric parameters and biochemical indices and daily nutrient intakes assessed by a 24-hour recall were collected before and after the intervention program., in order to evaluate program effectiveness. After the intervention, there were positive changes in exercise status and dietary habits and nutrition knowledge accuracy. Especially, the answer of 'I drink a cup of milk every day' were significantly improved (p<0.001), and the answer of 'I don't overeat', which is a dietary attitude question was significantly improved (p<0.05). Dietary intakes of most of nutrients were not significantly different between pre-test and post-test. But calcium (p<0.05), potassium (p<0.05), vitamin A (p<0.01), vitamin E (p<0.05), and folic acid (p<0.05) were significantly increased in the female group after the intervention. Weight (p<0.05), BMI (p<0.01), blood pressure (p<0.001), were significantly decreased after program, but changes of skeletal muscle mass, body fat mass were not significant. Resting heart rate (p<0.01), flexibility (p<0.001), whole body reaction (p<0.05), grip strength (p<0.01) and balance (p<0.01) showed positive changes after the intervention. Blood glucose level in serum was significantly decreased (p<0.001). These results indicated that dietary education and exercise program was effective not only for weight reduction but also for the improvement of physical fitness in obese adults.

BACKGROUND/OBJECTIVES: This study aims to develop a mobile nutritional management program for integration into the already developed web-based program, Diabetes Mellitus Dietary Management Guide (DMDMG) for diabetic patients. Further, we aim to evaluate the amended DMDMG program. SUBJECTS/METHODS: The mobile application based on an Android operating system includes three parts: 1) record of diet intake, which allows users to take pictures of the meal and save to later add diet records into DMDMG; 2) an alarm system that rings at each meal time, which reminds users to input the data; 3) displays the diet record and the results of nutrient intake, which can be also viewed through the web program. All three parts are linked to the web-based program. A survey was conducted to evaluate the program in terms of nutrition knowledge, dietary attitude, eating behavior and diet intake by non-equivalent control group design among diabetic patients with 14 DMDMG users and 12 non-user controls after a one-month trial of DMDMG. RESULTS: Non-users did not use the program, but participated in the weekly off-line nutrition classes for one month. The program users showed increased healthful dietary behavior (P < 0.01) and dietary attitude scores (P < 0.05). More DMDMG users had higher nutrition knowledge scores after one-month trial than non-users. However, dietary intake significantly increased in non-user group for calcium and sodium (P < 0.05) while the user group did not show significant changes. CONCLUSIONS: The program has created positive changes in patients' dietary life. All the users were satisfied with the program, although some expressed minor difficulties with an unfamiliar mobile app.

This study was performed to evaluate the differences in blood pressure, sodium intake and dietary behavior changes according to the extent of session attendance on sodium reduction education program for pre-hypertensive adults in a public health center. Sodium reduction education program consisted of 8 sessions for 8 weeks. Fifty three patients who completed the pre and post nutritional assessments were classified into 2 groups according to the session attendance rate. Nineteen participants who attended the education program 3 times or less (${\leq}3$) were categorized into the less attendance (LA) group and 34 participants attended 4 times or more (${\geq}4$) into the more attendance (MA) group. Blood pressure, anthropometric measurements, serum lipid profile, nutrient intakes including sodium, nutrition knowledge and dietary behavior score were assessed before and after the nutrition education program. Mean sodium intakes (p<0.001), systolic/diastolic blood pressure (p<0.001), and weight (p<0.001) were significantly decreased in the MA group after sodium reduction education program. Compared to the MA group, mean sodium intakes, systolic/diastolic blood pressure were not significantly changed after the education program even with significantly increased nutrition knowledge (p<0.05) and dietary behavior score (p<0.01) in the LA group. It appears that pre-hypertensive adults need to attend the sodium reduction education program for at least 4 times or more to gain beneficial effects from the intervention. Positive feedback of healthcare team or offering more cooking classes may be needed to raise the attendance rate in the sodium reduction education program.

This study was conducted to investigate weight control status and associated factors among health-related major female college students. The subjects consisted of 41 nutrition and 78 physical exercise major female college students. Nutrient intakes, biochemical index, nutrition knowledge (recognition and accuracy), interest of weight control, body satisfaction, self-recognition of health condition, self-evaluated body weight were studied. About 73% of nutrition and 79% of physical exercise major female students were in the normal range of BMI ($18.5{\sim}23$) and 2% of nutrition and 1% of physical exercise major female students were underweight, 10% of nutrition and 6% of physical exercise major female students were obese. There were no significant differences in height and weight by major but %body fat and WHR in physical exercise majors were significantly lower than nutrition major students (respectively p<0.01, p<0.05). Overall, nutrition intakes of subjects were not shown to be appropriate, especially Ca/P of subjects was shown $0.54{\sim}0.64$, fat% out of energy of subjects was shown $24.7{\sim}29.0$ and Na intake was shown above 2000mg. Recognition and accuracy of nutrition were higher than those of physical exercise majors (p<0.001). There were no significant differences in self-recognition of health condition, self-evaluated body weight, satisfaction of body shape by major and weight control attempt. But interest of weight control of attempter was higher than that of no-attempter in nutrition (p<0.05) and physical exercise major students (p<0.01). Significantly negative correlation was found in satisfaction of body and BMI, body fat mass, %bodyfat, WHR. And significantly positive correlation was found in interest of weight control and BMI, %bodyfat, WHR. It was noticeable to see that interest of weight control was positively correlated to accuracy and accuracy was negatively correlated to blood cholesterol level. Therefore, proper nutrition education for female college students is needed in order to improve their weight control-related health.
