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 identify adults' knowledge, dietary behavior related to sodium, the attitude towards a low-salt diet, and to examine the relation between these variables. The participants were 366 adults in Jeonbuk area. The data were analyzed using Pearson correlation coefficients, ANOVA and Duncan test with SPSS v. 12.0. The score for participants' knowledge about sodium was 12.32 points of a possible 16, the score for dietary behavior related to sodium was 45.74 points of a possible 70, and their score for attitude towards a low-salt diet was 30.35 points of a possible 50. The knowledge showed significant differences by gender (p<.05), and concern about health (p<.05). The dietary behavior of sodium use showed significant differences by gender (p<.001), age (p<.001), educational level (p<.05), job (p<.001), income (p<.05), BMI (p<.05), smoking (p<.01), drinking (p<.01), exercise (p<.05), regularity of health checkup (p<.001), and concern about health (p<.01). The attitude towards a low-salt diet showed significant differences by gender (p<.001), age (p<.001), job (p<.001), income (p<.001), smoking (p<.05), regularity of health checkup (p<.001), and concern about health (p<.001). There was a significant positive correlation between knowledge about sodium, dietary behavior related to sodium, attitude towards a low-salt diet. Dietary behavior related to sodium showed a positive correlation with attitudes towards a low-salt diet. In conclusion, it is necessary to consider the related factors for the development and implementation of systematic education programs that can encourage and promote preventive dietary behavior for disease, e.g. stomach cancer, and hypertension among adults.

This study was carried out to investigate the dietary attitudes, nutrition knowledge, nutrient intake, eating-related characteristics of dancing major and non-major female university students. The survey was conducted from October 1 to November 10, 2003 by questionnaires and data analyzed by SPSS program. The results are summarized as follows: 25.5% of the underweight group, 53.6% of the normal weight group, 12.5% of the overweight group and 66.7% of the obese group had correct perception about their body image. Eighty-one point three percent of the dancing majors and 77.2% of the non-majors were concerned about weight control, and 71.3% of the dancing majors and 64.5% of the non-majors had weight control experiences. There were no significant differences in nutrition knowledge scores and dietary attitude scores between dancing majors and non-majors. There were no significant differences in ‘predisposition to obesity scores’ between dancing majors and non-majors, and the scores were low. ‘Predisposition to anorexia’ scores and ‘uncontrollable urges to eat’ scores were significantly higher in the dancing majors compared to the non-majors. Intakes of the nutrients were lower than those of the Korean recommended dietary allowances (RDAs), except vitamin C in the dancing majors. Intakes of calories, calcium and iron were lower than those of the RDAs in the non-majors. Dietary attitude was positively correlated with nutrition knowledge but was negatively correlated with ‘uncont-rollable urges to eat’. In the dancing majors, ‘predisposition to obesity’ showed significantly positive correlation with obesity rate and ‘uncontrollable urges to eat’ and was negatively correlated with nutrition knowledge and dietary attitude. In the non-majors, obesity rate showed positive correlation with ‘predisposition to obesity’ and ‘uncontrollable urges to eat’. Therefore proper nutritional education program and recommended dietary allowances are required for dancing majors to improve their nutritional status.

Objectives: We aimed to examine health-related nutritional knowledge and dietary behavior related to caffeine intake among high school students (n = 310) in the Yongin region of Korea. Methods: Data were collected using a face-to-face survey, and analyzed using chi-square test, t- test, and logistic regression analysis. Results: The level of caffeine intake in respondents was divided into low (< 30 mg/d; n = 208) and high caffeine intake groups (> 30 mg/d; n = 102). Total nutritional knowledge related to bone disease was higher in the low intake group (score 2.75) than the high intake group (score 2.39; p < 0.05). The high intake group had lower scores for nutritional knowledge (score 0.70; p < 0.05) related to how caffeinated beverages affect sleep and for dietary behavior (score 3.25; p < 0.001), based on "I avoid caffeinated foods before sleep," than the low intake group (nutritional knowledge score, 0.80; dietary behavior score, 3.76). Conclusion: In the overall analysis, the low caffeine intake group had better nutritional knowledge related to bone and sleep health, and healthier dietary behavior related to sleep health compared with the high intake group.

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 performed to investigate the nutrition knowledge, dietary attitudes, and dietary behaviors among high school students by gender. The subjects were 275 students (127 male, 148 female) in Incheon metropolitan area. Self-administered questionnaires consisted of general characteristics and anthropometric data, nutrition knowledge, dietary attitudes, and dietary behaviors. The average score of nutrition knowledge was significantly higher in female subjects (9.4) compared to male subjects (8.2) (p<0.01). Male subjects had a higher score for dietary attitudes than female subjects (p<0.001). Frequency of meals was significantly higher in male subjects compared to female subjects (p<0.05). Duration of meal time in male subjects was significantly higher ('5-10 minutes') compared to female subjects (p<0.001). Unbalanced diet was significantly higher in female subjects (66.3%) compared to male subjects (48.9%) (p<0.01). Male subjects showed significantly higher consumption frequency of 'dairy' (p<0.001) and 'beans' (p<0.001) compared to female subjects. For snack consumption, male subjects showed higher consumption frequency of 'nuts' (p<0.001), 'soda' (p<0.05), 'fast foods' (p<0.001), and 'ramyeon' (p<0.01), but lower consumption frequency of 'biscuits and bakery' (p<0.01) compared to female subjects. Therefore, it is necessary to develop a systemic nutrition education program for high school students by gender.

Objectives: Diet and incidence of chronic diseases are highly related. This study examined the characteristics of dietary safety awareness and competency for chronic disease prevention among adults. Methods: Data were collected from 247 adults in Daegu and Gyeongbuk areas using a self-administered questionnaire in May and June of 2018. Data were analyzed by frequency analysis, χ²-test, factor analysis, reliability analysis, t-test, one-way analysis of variances, and correlation. Results: The results of the factor analysis indicate that dietary safety awareness of health management was classified into chronic disease anxiety and obsession. Awareness of dietary safety management was sub-grouped into difficulty in acquiring knowledge, lack of awareness of over and malnutrition, food safety anxiety, importance of weight management, education requirement for cancer prevention, and knowledge. Dietary safety behavior composed of a balanced diet, unhealthy diet, and health-functional pursuit. Dietary safety management competency was comprised of health management, food management, and cooking. The competency scores of dietary safety management factors were significantly different according to sex, age, and education level (P < 0.05). Balanced diet factor was significantly correlated with knowledge, health-functional pursuit, health management, food management, and cooking capacity factors (P < 0.01). Conclusions: Active education for dietary safety management competency according to age, gender, and education level should provide dietary safety education to reduce anxiety and obsession regarding chronic diseases and sustainable health management.
