Objectives: This study aims to identify self-resilience factors that drive right dietary and food safety practices in middle school students. Methods: Data was collected from 438 middle school students in Daegu using a self-administered questionnaire in December, 2013. The questionnaire consisted of 81 items with the following categories: general information, self-resilience, right dietary and food safety practices. Statistical analyses to determine frequency, average, ANOVA, factor analysis, reliability analysis, and regression analysis were performed using SPSS 21. Results: The results of factor analysis indicated that self-resilience was classified into challenge, adaptability, patience and achievement needs, and right dietary practices were sub-grouped into family meals, experience of dietary life, eco-friendly, balanced food, economy and bad food control, and food safety practices consisted of management of bacteria, hand washing and eating off a plate, safety food and food purchasing. The score of right dietary and food safety practices showed significant differences by sex, grade, and school achievement (p < 0.05). The economy factor of right dietary practices was significantly affected by the management of bacteria (p < 0.001), hand washing and eating off a plate (p < 0.001), safety food (p < 0.01), food purchasing of food safety practices (p < 0.05). The challenge factor of self-resilience significantly affected family meals, experience of dietary life, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and safety food (p < 0.05). The adaptability factor of self-resilience was associated with factors such as eco-friendly, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and food purchasing (p < 0.05). Conclusions: This study suggests that dietary education programs for middle school students could incorporate food safety practices, and self-resilience such as challenge, adaptability, patience and achievement needs to be effective.

This study investigated associations between healthy dietary practices and the odds of prediabetes among Korean adolescents. The data of 1,624 adolescents aged 12 to 18 who participated in the 2017-2021 Korea National Health and Nutrition Examination Survey were analyzed. Healthy dietary practices were defined according to Health Plan 2030 criteria, and prediabetes was defined as a fasting blood glucose level of 100-125 mg/dL. After controlling for confounders, adjusting odds ratios and 95% confidence intervals (CIs) for prediabetes were determined for different healthy dietary practices using multivariable logistic regression analysis. Compared with adolescents who engaged in healthy dietary practices, those who did not had a 1.63-fold (95% CI: 1.12-2.37) higher odds of prediabetes. In addition, adolescents who did not consume ≥500 g of fruit and vegetables daily and those who refrained from reading nutritional fact labels, which are both sub-indicators of healthy dietary practices, had a 1.66 (95% CI: 1.05-2.62) and 1.58-fold (95% CI: 1.06-2.37) higher odds of prediabetes, respectively, than those who did. Increasing the proportion of adolescents engaging in healthy dietary practices, such as consuming ≥500 g of fruit and vegetables daily and reading nutritional fact labels when selecting food, is imperative.

Green dietary education emphasized environmental protection and humanity being conducted in middle schools. To develop effective green dietary education program for adolescents, the factors that affected their green dietary practices has been identified. This study aims to identify psychological factors that drive green dietary practices and effect of dietary education that targets middle school students. Data was collected twice from 242 middle school students in Daegu using a self-administered questionnaire in March and June, 2014. There were significant differences in school achievement, economic level and allowance a month (p<0.05) in the green dietary practices and efficacy of students. Three areas (environment, health and traditional, and appreciation & consideration) which were subgroups of green dietary practices were associated with factors such as family relations, peer relationships, self-competence of self-esteem (p<0.05), and positive and negative feelings of happiness (p<0.001). Green dietary practices efficacy was significantly affected by family relations, peer relationships, self-competence of self-esteem (p<0.05), and positive feeling, negative feeling, and negative relationships of happiness (p<0.001). After green dietary education, interests in green dietary, green dietary practices score, the score of health and environment factors of green dietary practices efficacy significantly higher than before education (p<0.05), but all the factors of self-esteem and happiness did not have any significant changes. This study suggests that green dietary education programs for middle school students could account for psychological factors such as self-esteem, happiness according to gender, school records, economic level and allowance a month to be effective.

For the purposes of participation in research projects, living in a laboratory has become popular among male university students who tend to have less opportunity for nutrition education and overestimate their own health, suggesting possibilities of many undesirable practices of lifestyle and dietary habits. Therefore, this study was conducted to investigate and compare health-related lifestyle practices, dietary habits, nutrition knowledge, food preference and dietary behaviors of the male university students according to residence type. The subjects were 260 (34, 15, 44, and 167, respectively for lab-living, self-boarding, dormitory and commuting) male engineering majors in the Gyeonggi area. Self-administered questionnaires consisted of general characteristics, health-related lifestyle practices, dietary habits, fast food consumption, nutrition knowledge, preference for foods and tastes, and self-examination of dietary behaviors. Lab-living subjects showed many undesirable practices, particularly with more smokers (p < 0.05), irregular eating (p < 0.01), overeating (p < 0.05) and skipping breakfast (p < 0.01), compared to the dormitory students and more time in computer/TV usage (p < 0.05), overeating (p < 0.05), more frequent use of fast-food (p < 0.05), less nutrition knowledge (p < 0.01) and less intake of milk/dairy products (p < 0.01) and fruits (p < 0.01), compared to commuting subjects. More smokers (p < 0.05) and irregular (p < 0.01) and unrelaxed meal times (p < 0.05), compared to the dormitory group, and less intake of fruits (p < 0.01) and dietary fiber (p < 0.01), compared to the commuting group were shown as undesirable practices of the self-boarding group. Therefore, continuous effort should be made to correct undesirable health- and diet-related practices found in this study in order to improve nutritional status as well as general health by developing a nutrition education program and contents of lectures focusing on more specific problems according to each subgroup such as lab-living and self-boarding male university students.

Sustainable meal management at home will be affected by the lifestyle of the housewife. This study examined the lifestyle of middle aged women and identified their practice levels of sustainable meal management at home. A total of 438 women, aged 35 to 59, managing the family's dietary life at home and living in Seoul, Gyeonggi Province, Daejeon, and Chonnan area participated in the survey. The middle aged women showed a higher performance level of hygiene-oriented (4.15) and health-oriented dietary life (3.59), but a less convenience-oriented dietary life (2.57). Based on their lifestyle, 3 clusters were extracted: Low-interest dietary life meal manager, health and quality pursuit meal manager, and convenience and eating-out pursuit active meal manager. Among them, the cluster of health and quality pursuit meal manager showed the highest sustainable practices in 7 dimensions of sustainable practices in the home except for the saving practices (p<0.001). The criteria suggested from the study can be applicable to the guidelines of sustainable meal management at home. The study can also be helpful for educators to identify the education themes for improving housewife's sustainable meal practices, having different lifestyle and sustainable meal practices.

Objectives: This study attempted to compare adolescents' dietary behaviors and perceptions by gender in order to recommend useful strategies for nutrition interventions. Methods: Subjects were 2,363 middle school (MS) and high school (HS) students. They completed a self-administered questionnaire on their interest in diet and health, dietary perceptions, nutrition knowledge, dietary practices, and dietary environment at home. Data were analyzed using t-test, $x^2$-test, and simple regression analysis by gender and by school groups Results: Overall, girls obtained higher scores than boys did for "interest" (MS: p<0.001; HS: p<0.01), "dietary perceptions" (MS: p<0.001; HS: p<0.01), and "knowledge" (MS: p<0.01; HS: p<0.001). Regarding "dietary practices," no gender differences were observed among MS students, however, among HS students, boys obtained higher scores-reflecting good practices-than girls did (p<0.01). In all subjects, dietary environment at home was strongly associated with dietary practice than other variables (MS boys: ${\beta}$=0.435, p<0.001; MS girls: ${\beta}$=0.492, p<0.001, HS boys: ${\beta}$=0.271, p<0.001; HS girls: ${\beta}$=0.429, p<0.001). Conclusions: We observed gender differences in some of the variables such as knowledge and perception among adolescent students. Educational programs and core strategies that consider these gender differences need to be developed. Specifically, for girls, educational programs should focus on facilitating dietary recommendation adherence, whereas for boys, the program could focus on improving dietary knowledge and perceptions.

This study was to investigate the changes in dietary practices, reasons for making dietary changes, current food consumption patterns, and eating habits. Data were collected from 515 parents whose children were attending an elementary school and a middle school in Kimcheon. Among the twenty food groups studied, subjects reported eating more fruit, vegetables, lower-fat meats, high-fat meats, reduced/skim milk, and eggs and less sugar, fats, rice, salt, potato/sweet potato, and chicken. The changes in dietary practices except high-fat meats and salt were significantly different between sex, age, education level, income level, or BMI groups. The primary reason for making dietary changes was 'concerned about family's health'. The average rate of never eating breakfast or less than 2 times per week was found to be 23.2% with a greater rate in younger age group. The rate of breakfast skipping was found to vary between different age and education groups. The regularity of mealtime and overeating practices were significantly different between age groups. Eating out practices were found to vary between different age, education, and income groups. People at younger age group in Kimcheon should be targeted for nutrition education about eating habits. These findings are applicable at the planning and implementation stages of various nutritional improvement projects.

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 purpose of this study was to find out the dietary attitudes and behaviors, intake frequencies of food groups, health-related opinions and practices, and sociodemographic characteristics of housewives in Wonju-Gun rural area. Interviewers asked 413 housewives about obove informations and then recorded. The results were as followes : Using the factor analysis processing, 17 questions about dietary attitudes and behaviors were categorized into 5 groups such as fidelity of diet, the healthful dietary attitudes, the eating practices concerning about items and amount, eating speed and the extent of coincidence in food preference within a family. The role of the housewives was a major factor affecting the dietary attitudes and behaviors. Those who work as housewives and farmers concurrently had good dietary practices concerning about items and amount, but they were interested about health-directed dietary attitudes at a significantly lower level. Food frequencies of 9 groups, animal protein food, fruits and vegetables, milk and milk products, small fishes such as anchovy, soybean curd and beans, seaweeds, vegetable oil, frying food, soybean paste were significantly associated with subjects' age, role, and education and income level. Whether or not intake of soybean paste was considered. protein food intake was altered, and the difference between two situations increased much more as age was higher. We noticed that intake of soybean paste improved the status of protein nutrition. Our subjects ate calcium sources and dishes using vegetable oil insufficiently. Those who had much interests for good health, revealed to be an active practitioner in the aspects of healthful dietary attitudes, but fidelity of diet, eating practices concerning about items and amount showed significant association with balanced life style.
