This study was performed to investigate the effects oi nutrition education program in physical health, nutritional status and health-related quality of life (HRQoL) of the Elderly in Seoul. Nutrition education program was consisted of healthy eating, prevention and diet therapy of obesity, diabetes, cardiovascular disease, and osteoporosis. Seventy eight free-living elderly people (13 male, 65 female), aged ${\geq}60 $ years participated in this program. Before and after nutrition education program, we surveyed the general characteristics, physical health, general health, nutrition status, and health-related quality of life to the subjects. All the subjects were divided into program completers (N=47) and noncompleters (N=31). All the data were analyzed by student t-test, chi-square test, paired t-test, and marginal homogeneity test using SPSS 9.0 version at p<0.05. After nutrition education program, physical activity and ADL maintained, however IADL improved in program noncompleters. In eating habits, 'slow eating' significantly improved in program completers in program completers. Nutrition knowledge and recognition scores were significantly increased in both groups, and accuracy score was significantly increased in program completers. However, nutrient-intakes of %RDA were not significantly changed in both groups, and it seemed to be more influenced by other factors such as 'family income' or 'family type' than by the nutrition education program. In HRQoL, social functioning was improved after nutrition education program in both groups (p<0.05). The nutrition education program has more effects on the program completers than on the noncompleters, and it is also needed social supports for the Elderly to fulfill their nutrient requirements.

This study was to investigate the effect of the education about general nutrition knowledge on the acceptance of TV food advertisements in adolescents. Twenty hours of nutrition related education in home economics classes were done during 3 months, to conveniently selected 784 first grade middle school students living in large and small cities and rural areas of Chungnam Province. The education effects were evaluated through questionnaire surveys before and after the education and their comparative analysis. Average TV watching time was $29.2\pm1.16$ hours per day, which was about one hour longer on weekends. Nearly half of the subjects watched TV mainly after 9 PM. After nutrition education, nutrition knowledge scores of total subjects were significantly increased from $7.73\pm2.16$ to $10.25\pm2.51$ with a full score of 16. Food attitude and food habit scores also significantly increased from $32.45\pm4.65$ (full score 50) to $33.93\pm4.68$ and from $36.20\pm5.70$ to $37.29\pm5.87$, respectively. The general acceptance of TV food advertisements scored $25.25\pm4.44$ (full score 40) before education and $26.90\pm4.55$ after education, which was significantly raised by the education. Acceptance scores of TV food advertisements showed significant positive relationships with the scores of nutrition knowledge, food attitudes, and food habits. In addition, TV watching time had negative relationships with nutrition knowledge, food attitudes, and food habits scores, but not with acceptance score of TV food advertisements. The above results suggested that school-based nutrition education improved slightly but significantly the attitude of accepting TV food advertisements maybe through increasing nutrition knowledge and making food attitudes and habits better. Nutrition education focused on the evaluation and acceptance of food advertisements are further needed to improve the TV food advertisement acceptance of adolescents.

The present study was conducted to investigate the effect of iron-enriched cereal supplement and nutrition education program on nutritional status and life style of children. Elementary school students(n=170) aged of 11 years old at Seoul were participated. Subjects were supplemented with iron-enriched cereal for breakfast and provided with 2 sessions of nutrition education during 3 months. Intake of carbohydrate, iron, sodium, zinc, vitamin A, vitamin $B_1$, vitamin $B_2$, vitamin C, niacin, and folic acid was significantly increased after cereal supplement. Caloric intake was similar to KDRIs during both before and after cereal supplement. There was no improvement on exercise and dietary habits after nutrition education. Male students tended to sleep later, wake up early, and ate snack less than female. Cereal supplement was effective on improving nutritional status, but short-term nutrition education had no effect on modification of life style. Thus, further studies are required to develop long-term education program effective on improving lift style and eating habits in children.

The study involved a total of 1,978 male subjects aged 40~64 who were classified into the 2 groups based on their nutrition education experience: Educated group (n=88) and non-educated group (n=1,890). The household income and education level of educated group were higher than those of the non-educated group. The two groups showed no significant difference in the level of fasting blood sugar, blood lipid profile including total cholesterol and triglyceride, LDL-cholesterol, and hypertension. Vitamin C intake of the educated group (127.5 mg) was higher compared to the non-educated group (88.2 mg) (p<0.05). The percentage of the subjects utilizing nutritional labels was higher in the educated group. The nutrition education experience was inversely proportional to lower Odds Ratio in hyperLDL-cholesterolemia (OR: 0.47, 95% CI: 0.36, 0.84) and HypoHDL-cholesterolemia (OR: 0.57, 95% CI: 0.37, 0.87).

This study was designed to assess the needs for nutrition education and educational materials for older adults. Two cross-sectional surreys were conducted. The first survey, conducted by personal interviews, was part of the large-scale elderly nutrition study. Subjects were adults aged 50 and over, recruited from 6 large cities and 8 middle-sized cities(n = 1,850). The second survey, done by mail survey using open-ended questions, was conducted with dietitians working at public health centers or hospitals(n = 53). Adults aged 50 and over were interested in topics such as healthly eating(32.1%), hypertension/stroke and diet(22.1%), osteoporosis and diet(11.4%), and diabetes and diet(9.2%). Television and radio(58.2%), health professionals(12.2%) and friends(7.9%) were common sources of nutrition information. Preferred topics of nutrition education and sources of nutrition information were different by general characteristics of subjects, suggesting that nutrition education or educational materials be planned considering the characteristics of subjects. About 70% of subjects indicated that they sometimes use or do not use nutrition information in daily lives, suggesting the need to provide more practical information. Among 53 facilities responding to the second survey, 73.6% provided nutrition education for older adults. Common topics for nutrition education included diabetes(39.3%), hypertension and stroke(19.1%) and general nutritional management(11.2％). These were consistent to the topics preferred by older adults. As materials In elderly education, dietitians wanted primarily to use leaflets and slides. Boards, booklets and posters were other commonly cited materials. For contents of elderly educational materials, dietitians mentioned the nutritional management for age-related diseases(33.8%), general nutritional management for older adults(25.4%) and practically applicable information(19.7%). They also suggested that nutrition education materials for the elderly should use larger print and attractive pictures, and be easily understood, as well as presenting simple, specific and practical information. These results provide baseline information for developing nutrition education and educational materials for older adults.

This study was conducted to investigate the effects of educating 5th graders in elementary school about Korean traditional fermented soy products. The percentage of correct answers from the educated group increased after nutrition education compared to the non-educated group (p<0.001). The perceptions and attitudes regarding Korean traditional fermented soy products increased significantly after nutrition education (p<0.05). Analysis of the preference for Korean traditional fermented soy products based on participation in nutrition education showed that both groups were not significantly different in all categories including soybean paste, soy sauce, and red pepper paste. The investigation on differences in intake frequency of Korean traditional fermented soy products showed that both groups did not display statistically significant differences in all categories including soybean paste, soy sauce, and red pepper paste. These results confirmed that the nutrition education activity program had positive effects in correcting 5th graders' knowledge, perceptions and attitudes regarding Korean traditional fermented soy products. However, it did not significantly affect their preferences and intake frequency. This indicates that short-term education cannot effect changes in preference or actual behaviors. Therefore, continuous nutrition education activities are required.

The purpose of this study was to objectively quantify the effects of nutrition and dietary life education on preschoolers through meta-analysis. In addition, it provides basic data for the implementation of nutrition education and development of systematic nutrition and dietary life education programs. In this study, a meta-analysis of 27 papers was conducted that conformed to the selection criteria in the study conducted from January 2012 to August 2019 to derive objective data on the effects of education. As a result of the analysis, the overall effective size of nutrition and dietary life education for preschoolers was 0.829, which indicates a strong effect. According to the education method, the effect size of general education was 0.562, which indicates a medium effect size, the vegetable playing-based experience education was 0.685, which indicates a medium effect size, and cooking activity-based experience education was 1.101, which indicates a large effect size. Judging from this result, experience activity education was more effective than general nutrition education. In addition, the combined size of convergence education conducted through a combination of general and experience education was found to be the most effective at 1.301. In terms of educational effect, it was confirmed that the effect size was 0.898 for improving nutrition knowledge, 0.858 for improving dietary habits, 0.836 for improving unbalanced diet, and 0.756 for improving food preference and intake, and the sizes of effects were all found to be large. As frequency of education increased, the number of education participants decreased and the effect of education increased.

Low energy intakes, poor nutritional quality, and low food diversity are among the factors affecting the nutritional status of elderly in Korea. Therefore, a nutrition counseling and education program was conducted to promote dietary change and to improve nutritional status of elderly. The 7 step program consisted of a individual nutrition counseling and weekly or biweekly group nutrition education programs. Pre- and post-test measurings of dietary behaviors, attitudes, nutrition knowledge, and 24-hour dietary recall data were collected. Positive changes in the attitude related to diet were noted, whereas nutritional knowledge scores were not improved. Significant increases were noted in the frequency of vegetable consumption in female and diversity of food consumption in male. The densities of vitamin C(male & female), $B_1$, $B_2$, and niacin, calculated using the INQ(Index of Nutritional Quality), were significantly improved by nutrition counseling and education programs. These results suggest the appropriateness of nutrition intervention programs for the improvement of elderly nutrition.

This study was conducted to investigate the effect of sodium reduction education program of a public health center on the blood pressure, blood biochemical profile and sodium intake of hypertensive adults. The program continued for 16 weeks with an 8-week nutrition education and an 8-week follow-up to forty two subjects, 6 males and 36 females aged 46 to 80 years. Subjects received nutrition education including lectures, activities, cooking classes and nutrition counseling. Physical fitness, management of stress, and nutrition counseling were provided during the follow-up. The program was evaluated three times, before and after the nutrition education, and after the follow-up. Systolic blood pressure (p < 0.0001) and diastolic blood pressure (p < 0.001) were decreased after completion of the program. Body weight (p < 0.005), percent body fat (p < 0.005) and body mass index (p < 0.001) were decreased, too. There were no significant differences in blood glucose, HDL-cholesterol and triglycerides, while elevated levels of total cholesterol (p < 0.001) and LDL-cholesterol (p < 0.001) appeared after the program completion. Decreased intakes of vitamin A (p < 0.05), ${\beta}$-carotene (p < 0.001) and sodium (p < 0.001) were observed. Consumption frequency of noodles, soups, stews, kimchi, fishes/shellfish, seasoned vegetables, and salted seafoods/pickles (p < 0.05~p < 0.001) were decreased, while that of all food groups were not changed during the follow-up. Total score of nutrition knowledge related to sodium intake and hypertension (p < 0.001), and that of dietary behavior associated with high sodium intakes were changed positively (p < 0.001) only during the nutrition education. This sodium reduction education program, including the follow-up study showed positive effects on the blood pressure, sodium intake, nutrition knowledge and dietary behavior of hypertensive adults.
