The purpose of this study was to investigate the effect of cooking activities on the unbalanced dietary food habits of elementary school students and develop the effective cooking activity program for the improvement of unbalanced dietary behaviors as well as the food intake and menu acceptance. The subjects of this study were 256 elementary school students. The cooking activity group and control group were consisted of 128 students of $3^{rd}$ & $5^{th}$ grader each. Both cooking activity and the control group took the same 1-hour nutritional theory based class for 10 sessions. Only Cooking activity (CA) group took additional 10 sessions of 1-hour cooking class. Programs for cooking activity were developed and 10 cooking activity sessions were taken place for 4 months. The questionnairs were used to evaluate the effect of the cooking activities over the intake of food group, unbalanced dietary behavior, eating attitudes, menu acceptance before and after the completion of all the cooking activities. Cooking activities affect the unbalanced dietary behaviors and the intake of food groups. Fish, cereals, milk products, fruits, potatoes, vegetables were more eaten by CA group than control group. Eating attitudes and unbalanced dietary behaviors of CA group are also improved significantly than control group. From these results, it was concluded that cooking activities had the positive effect on the improvement of unbalanced dietary food habits over vegetables, cereals, fish, milk product and fruits as well as the unbalanced dietary behaviors of the elementary school children.

148 male and 153 female college students attitude toward weight control, diet behaviors and food habits were investigated by self questionnaire. Among the students, underweight students were 11.0$\%$, normal weight students were 63.5$\%$ and obese students were 25.6$\%$ by RBW standard, and underweight students were 16.0$\%$, nromal weight students were 70.4$\%$ and obese students were 13.6% by BMI standard. However, more than 10% of male and 38$\%$ of female students thought they were obese even thought their body weight were normal. Female students tended to overeat when they were stressed or in a bad mood and generally all participants had poor scores on the dietary attitudes test, however, male students had significantly higher scores than female students. Female students tended to choose food more for its taste. Collegestudents are in early stage of adult life and their dietary attitudes, food behaviors and life style will continue to their later life. Therefore college students need more good nutrition knowledge, positive dietary attitudes, modified life styles to prevent and treat collegestudents obesity.

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.

The purpose of this study was to compare regional differences in salty taste assessments, nutrition knowledge, dietary attitudes and dietary behaviors associated with high-salt diets in four national regions in Korea (Region 1: Seoul, Sokcho, Region 2: Buyeo, Jecheon, Gong Ju, Region 3: Daegu, Gyeongsan, Region 4: Jeon Ju). Subjects were 860 persons who participated in sodium reduction campaign. The result of the salty taste assessment by region was not significantly different. The nutrition knowledge score of subjects in Region 1 was the highest. Dietary attitude scores that showed preference for high-salt diets of Region 2 and Region 4 subjects were higher than those of Regions 1 and 3 subjects (p < 0.001). Dietary behavior scores were not significantly different among regions. The correlation between sodium intake and salty taste assessment was significant (p < 0.01). Older subjects who had high blood pressure levels and lower nutrition knowledge were more likely to have high sodium intakes. Even though the salty taste assessment and dietary behavior scores by region were not significantly different, the salty taste assessment scores had a significant negative correlation with nutrition knowledge and had a significant positive correlation with dietary attitude and dietary behavior in terms of preference for high-salt diets. Therefore, nationwide education regarding salt intake reduction and health and a campaign to encourage favorable attitudes and behavioral changes regarding consumption of a no-salt / low-salt diet is needed.

The purposes of this study were to investigate the perception of nutrition labeling on restaurant menus, and to analyze the differences among subject's characteristics, eating-out behaviors, and dietary attitudes. Information concerning general characteristics, health status, eating-out behaviors and dietary attitudes of subjects was collected by a structured questionnaire. From January 5th to February 27th in 2009, 406 questionnaires were completed by 157 males and 249 females. Statistical analyses were performed using by SPSS 14.0 package program. The perception of the importance of nutrition labeling was 3.89, while knowledge of whether restaurants provided sufficient nutrition information scored 2.26 indicating that being highly conscious of nutrition labeling, respondents did not view the supplied information as sufficient. Nutritional perception was greater in females and varied in both genders with age and health status. Significant differences concerning the perceptions of nutrition labeling were evident, based on eating-out behaviors and dietary attitudes. The results imply that nutrition labeling on restaurant menus should be based on consumer characteristics. Relevant nutrition labeling might help improve health by encouraging proper dietary habits and providing valuable nutritional information. Recognition of the importance of nutrition labeling and strategic implementation of labeling in menus would be prudent strategies for restaurant managers.

This study was conducted to investigate the nutrition knowledge, dietary attitudes, dietary behaviors, smartphone usage-related dietary habits, and health-related lifestyles of higher grade students in elementary school according to risk level of smartphone overdependence. Subjects were 286 fifth and sixth grade students of elementary school in the Siheung and Ansan areas. Data were collected using self-administered questionnaires and analyzed using SPSS v. 20.0. Based on scores of S-scale (smartphone overdependence scale for adolescents), subjects who used smartphone were classified into an overdependence group (ODG, n=52) and a normal group (NG, n=234). The ODG showed a significantly longer usage time than NG on both weekdays and weekends (p<0.001). There were no significant differences in total scores of nutrition knowledge between the ODG and NG. Average total scores of dietary attitude and dietary behavior in the ODG were significantly lower than in the NG (p<0.001). There were higher risks of ODG for skipping meals (OR=8.3, 95% CI=4.027-17.099), changing eating speed (OR=4.4, 95% CI=2.209-8.822), and changing meal amount due to smartphone usage (OR=2.9 95% CI=1.233-6.623). Therefore, education programs are needed to ensure proper dietary behaviors and habits among smartphone overdependent elementary school students.

This study was undertaken to investigate the association between maternal nutrition knowledge, dietary attitudes, and behaviors related to sugar intake and sugar intake reduction in preschool children. Eighty-three children aged 5 to 6 years attending kindergartens in Hongseong and their mothers participated in this study from October 2020 to February 2021. The average age of the mothers was 38.7 years, and 53.0% of the children were male. As child age increased, nutrition knowledge of sugar intake reduction increased, but no relation was found between age and, dietary behavior and preference related to sugar intake reduction. For children whose mothers perceived that their child's sugar preference was high, the behavioral score of sugar intake reduction was low. The more mothers allowed their children to eat sweet food; the higher was their child's preference for sweet food, which was also significantly associated with an increased risk of high sugar intake. When mothers were provided education that encouraged reducing children's sugar intakes, knowledge about reducing sugar intake in children was significantly increased. The study emphasizes the importance of the roles of mothers and primary caregivers regarding reducing the sugar intakes of preschool children.

The purpose of this study was to compare dietary attitudes, dietary behaviors and diet qualities of Food and Nutrition major and non-major female student at a university located in Inchon. The subjects included 74 female Food and Nutrition and majors and 45 non-Food and Nutrition major female university students. This cross-sectional survey was conducted using a self-administered questionnaire, and the data were analyzed by a SPSS 10.0 program. The nutrient intake data collected from Three-day recalls were analysed by the Computer Aided Nutritional Analysis Program and then the diet quality was estimated using the Mean Adequacy Ratio (MAR), the Nutrient Adequacy patio (NAR) and the Index of Nutritional Quality (INQ). There was no significant difference in dietary behaviors between Food and Nutrition majors and non-majors. However, most of the female university students had poor eating habits, such as overeating, unbalanced meals, and skipping of meals. In particular, more than 50% of the female university students skipped breakfast. As for weighing themselves once a week, changing dietary lifestyles, calculating food calories and having interest in information on nutrition on health, the ratio of Food and Nutrition majors was significantly higher as compared to that of the non-majors. There was a significant difference in food consumption frequency except for mick and milk products, and iron-rich foods between the Food and Nutrition majors and non-majors. However, there was a significant difference in the frequency scores of iron-rich floods between the Food and Nutrition majors and non-majors. The MAR of Food and Nutrition majors and non-majors were 0.80$\pm$0.13, 0.79$\pm$0.13, respectively. However, in the Food and Nutrition majors and non-majors, the NARs of calcium were 0.61$\pm$0.21 and 0.59 $\pm$ 0.20, and that of iron were 0.61$\pm$0.21 and 0.59$\pm$0.16, respectively, which was extremely low when compared to that of the other nutrients. This result was similar to that of the INQ. Therefore, nutritional education is necessary if female university students are to practice optimal nutrition, including well-balanced diets and eating foods of high nutritional quality.

Acculturation may manifest dietary behavioral changes of students from overseas. This study investigated the dietary attitudes, food intakes, and dietary behaviors of 121 Chinese college students residing in Busan, Korea. Using a focus group interview and structured survey, subjects were divided into two groups (SG, LG) based on their self-rated acculturation status. The SG (n=70) and LG (n=51) groups consisted of participants that had resided in Korea for shorter than 18 months versus 18 months or longer, respectively. The SG group was more likely to point out the taste of Korean foods as being too sweet, salty, and spicy but less greasy. A food frequency questionnaire was developed to assess normal intake of Korean ethnic, Chinese ethnic, and common foods. The LG group consumed more Korean foods such as rice cake, dried laver, and radish kimchi but less Chinese foods such as bread glue ball and kidney bean. The LG group consumed more salty and fatty foods and Korean liquors, whereas the SG group consumed more fruits and noodles. Based on the exploratory factor analysis, the SG group showed significantly higher scores for "dietary regularity" but lower scores for "indulgence of unhealthful food" factors. In summation, the LG group became more accustomed to Korean foods and adopted less desirable dietary behaviors compared with the SG group. Findings suggest that the residential period of Chinese college students may be associated with their self-rated acculturation status and food acculturation process, and therefore tailored nutrition education programs are needed to support Chinese students' healthier dietary behaviors and food acculturation process.
