The purpose of this study was to evaluate the effectiveness of nutrition education with nutrition services provided by dietitians who were placed in child care facilities from the Korean Dietetic Association. For this, we investigated the levels of nutrition knowledge and dietary intakes of children who attended child-care centers as well as dietary practices of children assessed by their parents. The treatment for children consisted of nutrition education and food service activities that are provided by the dietitian who have 3 to 5 years experience. Nutrition education was implemented during 10 weeks, 20 times, and a total 400 min and it's effectiveness was evaluated by questionnaire. Data were obtained for 123 children aged 4 to 5 years old who attended four child-care centers, one for a control group and 3 for intervention groups. Dietary intakes were investigated by measuring one-serving size and plate waste a of child for one-day dietary records before and after nutrition education. The levels of nutrition knowledge of children improved showing 70.80 points before to 83.45 points after nutrition education (p<0.001). Dietary intakes of the children after nutrition service increased significantly on cooked rice (133.66 g), Kimchi (19.41 g), side dish of meat/fish (48.40 g), and side dish of vegetables (24.88 g). Dietary practices of children after treatment also improved especially 'eat diverse meat, fish, egg, and bean' and 'never leave plate waste'. To summarize, this study pointed out that nutrition service and nutrition education provided by dietitians had influences on increases of the nutrition knowledge, dietary intake, and dietary practices. Therefore, placement of dietitians needs to extend to child care facilities from the 100 persons-over-capacity facility to the 50 persons-over-capacity facility, for providing professional service such as nutrition education and nutrition counseling.

The purposes of this study were to survey the present situation of nutrition education in junior/senior high school, to analyze the difference between the favorite subjects on students and the existing subject done by dietitians on nutrition education, and then to identify the subjects of nutritional education for junior/senior high school students. Self-administered questionnaires were given to dietitians and students and 142 of the 200 dietitians (71.0%) and 479 of the 564 students (84.9%) responded to the questionnaire on the nutritional education. According to the survey results, 76.1 % of school dietitians currently were doing nutrition education for students while the other 23.9% didn't have such education programs even though they recognized the necessity strongly. The target of nutrition education was student rather than parents or teacher generally and the principal measuring method for nutrition education effect was change of plate waste and leftover'. It was found that significant difference in the collector and source of nutritional education information between junior and senior high school dietitians (p< .05) . About ninety-eight percentage of dietitians felt that nutrition education should keep pace with meal service and this meant that almost respondent recognized the necessity of nutrition education for students. Because the most serious one among operational problems of nutrition education program was lack of enough time owing to too many affairs as dietitian, junior and senior high schools should support so that dietitians would share enough time for nutrition education. And also, a gap was existed between actual and favorite subjects on nutrition education. Significant differences existed in the following subjects; 'basic concept of food and nutrition', 'disease and nutrition', 'food culture in the world', 'cooking and culinary art', 'food of the 24 divisions of the year in the lunar calendar', 'food waste and environmental issue', 'food habit and food behavior', 'exercise and nutrition' (p< .001) 'table manner', 'food and individual sanitation', 'recommended dietary allowance' (p < .01) and 'menu planning' (p< .05) .Finally, 24 subjects of nutritional education were selected based on the survey results. These subjects would be expected to be able to contribute the effective and interesting nutrition education program for junior and senior high school students.

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 conducted to evaluate the effects of a set of 16 nutrition education lessons on the eating behaviors and nutrition knowledge of middle school students. The target was a group of 128 boys in the first year of middle school in Changwon, who took the classes from the 29th of August, 2011, to the 17th of February, 2012. The education was performed for 16 weeks using the e-learning textbook, 'Health and nutrition of youth', and a teacher's guidebook developed by the Ministry of Health and Welfare. The results were summarized as follows. Students demonstrated significant changes in their knowledge about nutrition and in their dietary behavior due to the nutrition education, and the effects were observed to be maintained for one year after education. The average nutrition knowledge score before, immediately after, and 1 year after the education was significantly increased from 13.0 before the education to 18.8 after education (p<0.001), maintaining the score of 18.5 1 year later. The eating-related questions of 'I will practice healthy eating habits in life' and 'Nutrition education is necessary to build healthy eating habits', were given a high score by the students at the last survey conducted one year later. Of course, it is not easy to change the dietary behavior of students through dietary education in schools. Nevertheless, the results of this study demonstrated that such educatcan is necessary since the habits can indeed be changed, as observed in the present study.

Eating behavior change as a result of nutrition education interventions as secondary prevention strategies can contribute to an increase in life expectancy and better health for older adults in the United States (U.S.). Many of the chronic conditions prevalent in older adults are modifiable by dietary changes, including heart disease, diabetes mellitus, hypertension, obesity and osteoporosis. Important demographic observations in the U.S. including the projected large increase in number of older adults by 2030 have implications for nutrition education focus and services. A comprehensive review of nutrition education interventions for older adults in the U.S. published in 1995 identified elements from adult education theories that contribute to the effectiveness of nutrition education. These elements have been the focus of more recent studies with older adults providing additional evidence for relationships between concepts from commonly used behavior change theories and dietary patterns or change. In the U.S, an important program contributing to nutritional adequacy of the diet for older adults is the Elderly Nutrition Program which provides resources for congregate dining and includes a mandatory nutrition education component. Nutrition education is also provided through clinic based programs, and print and broadcast media. Application of the Transtheoretical Model has shown that the level of interest or motivation to comply with dietary guidance may be greater for some older adults due to an increasing burden of chronic disease and poorer quality of life, while others may not feel a need to change lifestyle habits.

This study evaluated effects of food additive nutrition education on food additives-related knowledge, subjective awareness, and perception and dietary behaviors of food label use and processed-food intake. The study subjects were 5th grade students attending an elementary school in Seoul. A total of 101 subjects were assigned to either education (N = 50) or control (N = 51) group, and 3 food additive nutrition education classes were implemented to the education group. Self-administered questionnaires were collected from all the participants twice, a week before and after the nutrition education to compare the changes between two groups. The food additives-related knowledge and subjective awareness significantly improved in the education group compared to the control group. The changes in perceived harmfulness and perceived necessity for taste were also detected significantly different between the two groups, with more positive changes in the education group. Dietary behaviors of checking food labels and trying to purchase processed-foods with less food additives improved in the education group at a significant level in comparison with the control group. Additionally changes in intake frequency of several processed-food items were significantly different between the groups, again in a more positive direction in the education group. The study findings showed short-term food-additive nutrition education including hands-on activities could positively modify elementary school children's food additives-related knowledge, perception, and certain dietary behaviors, stressing better settlement of in-class nutrition education within an elementary school's education curriculum.

Objectives: The purpose of this study was to evaluate the effect of nutrition education using materials based on social cognitive theory. Education topics focused on improving health-related and dietary self-awareness and behavior capability in adolescents. Methods: Participants were recruited from a middle school for girls; 67 students (educated group, n=34 and control group, n=33) participated. The education group received 12 lessons in club activity class. Self-administered surveys were conducted for each group before and after the nutrition education program. The questionnaires consisted of variables such as self-efficacy, outcome expectation, outcome expectancy, knowledge, and dietary practices based on the social cognitive theory. Education satisfaction was evaluated using a five-point Likert scale for two sections: a) teaching and learning and b) education results. The data were analyzed using a t-test and Chi Square-test (significance level: p < 0.05). Results: In the education group, post-education, there were significant differences in self-efficacy (p < 0.05), knowledge (p < 0.01), and dietary practices (p < 0.05), whereas outcome expectation and expectancy did not show any significant differences. None of the variables showed any significant differences in the control group. Educational satisfaction scores were $4.38{\pm}0.12$ (teaching and learning) and $4.14{\pm}0.15$ (education results). Conclusions: This study showed that improving adolescent's awareness and behavior capability has a positive effect on their dietary practices. Moreover, this study suggested that a theory-based determinant should be considered to improve dietary behavior among adolescents.
