The purpose of this study was to examine the effect of nutrition education about the Korean food guide to middle school students on food intake measured by food frequency. Three hundred first graders were sampled from two coeducational middle schools located in the small city of Chungnam area, and divided into 167 (74 boys, 93 girls) education groups of one school and 133 (70 boys, 63 girls) non education groups of the other school. Nutrition education was given to the education group for a total of 16 hours and no education to the non education group during the same period. After education, average nutrition knowledge scores of education group increased from $6.40\pm2.17\;to\;6.81\pm1.56$ significantly especially boys with a high range of increase and girls no increase. Dietary habit scores improved significantly from $46.2\pm6.5\;to\;49.1\pm6.2$ in both boys and girls of education group. Of the knowledge and dietary habits, ability of choosing a balanced meal, biased eating to some food, and taking diverse foods at every meal improved significantly in education group. In non education group no significant increases of either nutrition knowledge scores and dietary habit scores were shown. In addition education group showed significant increases after education, in the intake frequencies of rice$\cdot$noodle$\cdot$loaf bread, kimchi, green and yellow vegetables, and soybean$\cdot$soybean curds by 0.27, 0.23, 0.40 and 0.32 servings per day, compared with non education group. These changes were greater in girls than in boys. According to these results, it can be concluded that nutrition education about the Korean food guide improved effectively not only student's nutrition knowledge and dietary habits, but also healthy food intake ability. It is necessary to prepare long-term and continuous school-based nutrition education programs for the students to get into a habit of healthy food intake.

This study was conducted to examine the nutritional knowledge and dietary habits by gender and a mother's employment status for middle school students. The subjects consisted of 423 students (212 boys and 211 girls). As for mother's employment status, 61.7% of the mothers were working, and 38.3% were housewives. The results from the analysis on differences of nutritional knowledge and dietary habits showed that girls tended to have a higher nutritional knowledge than boys (p<0.01). In terms of dietary habits, boys appeared to have more desirable eating habits than girls. As for the mother's employment status, only students whose mothers were doing housework tended to have higher nutrition knowledge and more positive dietary habits than students whose mothers were working. The influence of nutritional knowledge was found to have a significant effect on dietary habits (p<0.001). In addition, nutritional knowledge (B=0.168, p<0.01) turned out to have an influence on dietary habits, where a higher nutritional knowledge produced more positive dietary habits. Considering the results described above, nutritional knowledge appears to have a significant influence on dietary habits. Therefore, instructions on the importance of nutritionally well balanced meals must to be reinforced in nutritional education.

The purpose of this study was to improve the dietary attitudes and habits of elementary students in lower classes through a 12-week practical nutrition education program called KHIDIKIDS, which was developed by Korea Health Industry Development Institute (KHIDI) in 2004 based on the 2003 Children's Dietary Guidelines of the Ministry of Health and Welfare of Korea. KHIDIKIDS has never been applied in the field, therefore, another purpose of this study was to evaluate the program in the school education and suggest the ideas for the improvement. KHIDIKIDS was applied to a class of 2nd-grade elementary students consisting of 28 children in Seoul during the fall semester of 2005, and the effect of the program was measured by using questionnaires for the students and their parents. The statistical analysis of the study was conducted by using SPSS WIN 11.5 program, and the results were as follows: The children's knowledge on nutrition was improved significantly by KHIDIKIDS education (p<.001), such that the average score on nutritional knowledge increased from 8.32 to 9.64 after education. This practical nutrition education program also improved the dietary attitudes and habits of children especially in healthy body weight, daily exercise, and having breakfast (p<.05). Parents also showed very positive responses for the nutrition education. During the application of KHIDIKIDS in the field, the followings were indicated for adjustment, First, some education content of the week was too much to be finished in a class hour and more hours need to be allocated. Second, some terminology need to be adjusted to help the students understand easily. Thirdl, the order of the's Basic Food Groups' needs to be matched with the order of each food group in the 'Food Tower' not to make children be confused. Above results showed that KHIDIKIDS was effective for the improvement of dietary attitudes and habits of lower elementary students. However, further educational effects would be achieved when the education was started from the 1st to higher grades along with the parents' participation.

Our society is aging rapidly, and the number of elderly people who are in charge of purchasing and preparing foods at home is increasing. However, most the elderly have difficulty managing nutrition and food safety by themselves. The purpose of this study was to develop the necessary knowledge, through focus group interview and Delphi technique to establish a food safety and nutrition education program. The diet and educational needs of the elderly were surveyed through FGI. The education topics were decided by the Delphi technique. The education program consisted of a five week program, and the topics taught were 'Dietary Change for Healthy Life', 'Prevention of Food Poisoning in Everyday Life', 'Safe Food Handling for my Health', 'Healthy Dietary Life to Prevent Chronic Disease', and 'Safety! Nutrition! Healthy Dietary Life'. This education program was designed to decrease the perceived barriers, and to increase the perceived interests and the sense of self-efficacy. Education program materials, lesson plans, slides, handouts, videos, leaflets, and booklets were developed. Based on the results, the contents of the food safety guideline leaflets for the elderly were decided as the following: (1) wash your hands in the correct way; (2) select safe food; (3) cook foods safely; (4) keep foods safely; (5) keep kitchen utensils clean. In conclusion, if advanced education programs are implemented and delivered continuously in locations such as health centers and community welfare centers, those will contribute significantly to enhance the perception of food safety and to change the desirable dietary behavior of the elderly.

This study examined the background of the dietary life of North Korean defector adolescents born and raised in North Korea and their new South Korean dietary experiences after being settled in South Korea. The study included six North Korean defector adolescents enrolled in an alternative school located in Gyeonggi-do, South Korea. This study's qualitative research methodology included two-by-two group interviews, followed by individual interviews and field observation. The study period was from September 14 to October 26, 2019. Before entering South Korea, they primarily ate food pickled with soybean and salt, a cooking method by which foods are preserved because refrigerators were unavailable. After settling in South Korea, they had difficulty adapting to South Korean foods because of the unfamiliar ingredients and recipes. On the other hand, they quickly adapted to some foods, such as chicken. The participants reported that North Korean foods are generally light, whereas South Korean foods are sweet, salty, and spicy; hence, they do not taste delicious. The results suggest that attention be paid to menu improvement and the provision of nutritional education by schools and the government to prevent undernourishment or malnourishment because of unfamiliar ingredients and recipes.

BACKGROUND/OBJECTIVES: Proper nutrition intake during pregnancy and lactation is very important to both mothers and babies. Pregnant women should maintain proper nutritional status to restore decreased physical strength due to pregnancy and childbirth and produce breastmilk for the growth and development of the baby. Recently, the number of Chinese people living in Korea has increased as the exchange between Korea and China becomes active. It is important to provide proper nutrition education for pregnant women of both countries considering cultural differences. SUBJECTS/METHODS: The subjects of this study were postpartum women in Gyeonggi, South Korea and Jinhua, China. The subjects were 20-45 years old less than six months after childbirth. A survey, using self-administered questionnaires, was conducted from October 2018 to January 2019. For data analysis, 221 Korean postpartum women (KPW) and 221 Chinese postpartum women (CPW) questionnaires were used. RESULTS: KPW had significantly higher nutritional knowledge score and dietary attitude score than CPW (P < 0.001). However, overall score for dietary habits was significantly higher in CPW compared to KPW (P < 0.001). In KPW, nutritional knowledge (P < 0.01) and dietary attitude (P < 0.001) had significantly positive correlations with dietary habits. The proportions of KPW and CPW who answered that they had experience of nutrition education were 28.5% and 80.1% (P < 0.001). The score for dietary habits was lower as the hours for watching TV and using mobile phone became longer in postpartum women of both countries, with significant differences in KPW (P < 0.001) and CPW (P < 0.05). In KPW, the score for dietary habits in postpartum women with exercise experience was significantly higher than that in postpartum women without exercise experience (P < 0.001). CONCLUSIONS: More pregnancy-related nutrition education should be provided and various and effective nutrition education programs, which not only transfer information but can be practiced in the actual life, should be developed.

Objectives: This study was conducted to evaluate the nutrition quotient (NQ) by mother's parenting style which may influence the NQ in preschool children. Methods: Subjects were 310 mothers and their 4-6 year old children. The questionnaire composed of demographic characteristics, mother's parenting style at meal time and eating behavior as measured by NQ questions. The NQ questions consisted of 19 food behavior checklist items and all items were grouped into 5 factors: balance, diversity, moderation, regularity, and practice. Mother's parenting style was classified by using words for nutrition education at meal time. All data were statistically analyzed by SPSS program (Ver. 23) and the statistical differences in variables were evaluated by Student's t-test, ${\chi}^2$-test, One-way ANOVA. Results: We observed that in children whose mothers use the parenting style at meal time of 'explanation' and 'compliment & cheer up' had high dietary regularity, diversity, practice. The children of mothers who use the parenting style at meal time of 'persuasion' and 'reward' were found to have a lower degree of balance, diversity, and practice. Especially, children of 'reward' style mothers had lower moderation of dietary life. On the other hand, among the parenting style at meal time of 'comparison & demand', 'treating' and 'faire', there was no significant difference in the NQ factor by each group. NQ grade was higher among those who used more explanation (p < 0.001) and persuasion (p < 0.01) and with use of less persuasion (p < 0.01) and reward (p < 0.01). The positive association observed between the frequency of dietary education of mothers and higher NQ grade indicated the degree of dietary practices of those children. On the other hand, the children of mothers who rarely practice the dietary education at home had lower NQ grade (p < 0.001). Conclusions: In order to promote children's proper dietary behaviors, it is important to provide nutrition education to children as well as provide guidance on parenting style at meal time.

The purpose of this study was to compare the differences in the quality of dietary and life across age groups of Korean adults. According to life cycle, four age groups (20~29, 30~49, 50~64, ≥65) were created. Anthropometric indices showed significant differences according to age group (p<0.001). Energy intake significantly decreased according to age group as a result of decreased protein and fat intake (p<0.001). The intake levels of minerals, vitamins, and dietary fiber per 1,000 kcal were the lowest in the 20~29 age group (p<0.001). Whereas saturated fatty acids, MUFA, and PUFA intake levels were the highest for those in the 20~29 age group (p<0.001). The quality of dietary (DQI-I) increased with age group, but the quality of life (EQ-5D index) decreased (p<0.001). The quality of dietary showed 5.8% explanation power on the quality of life (p<0.001). Additionally, diet moderation was shown as having a negative effect, but the diversity and balance of diets had a positive effect on the quality of life. By age group, the relationship between quality of dietary and quality of life was the highest in ≥65 age group. These results suggest that practical dietary education is needed from the 20's to ensure the quality of healthy life for the elderly.
