This study was performed for the purpose of establishing proper dietary behaviors and improving sodium intake status by investigating nutrition knowledge, dietary behaviors, and food intake frequency related to sodium in 398 university students living in Gyeonggi-do and Incheon. Female students showed a higher rate of eating out more than five times a week as well as daily snack intake than male students. Female students showed a higher score for sodium-related nutrition knowledge than male students, whereas male students showed higher sodium intake than female students. Subjects who showed a higher frequency of eating out and snack intake also showed a higher salt intake ratio and sodium-related nutrition knowledge. Subjects with higher scores related to sodium-related nutrition knowledge showed a higher low salt intake ratio and incidence of low sodium food intake. From this research, depending on the level of nutrition knowledge related to sodium university students showed differences in dietary behavior related to sodium intake. This result would be helpful to develop lower sodium training materials specific to low sodium food selection tips, reading nutrition labels, and so on.
Osteoporosis is a major health problem confronting middle-aged women today. Enhancing calcium intake in early adulthood can increase the rate of calcium gain in bone. In this study, we investigated the association of bone health-related nutritional knowledge levels with calcium-related dietary behavior and nutrition education among women. Data were collected using questionnaires from 347 women aged 20~30 residing in Gyeonggi-do. Subjects were categorized into two groups according to their bone health-related nutritional knowledge (high or low-knowledge group). Knowledge related to bone health and calcium, and dietary habits was assessed, and the preference for and intake frequency of calcium-rich food were collected and analyzed using food frequency questionnaires. The high-knowledge group showed a significantly higher rate of nutritional education experience (33.9%) when compared with the low-knowledge group (18.9%). Not only were the perceptions regarding milk and dairy products more positive in the high-knowledge group (P<0.05), but the intake frequency of calcium-rich foods, such as tofu, soybean, and anchovies, was also higher in this group compared to the low-knowledge group (P<0.05). Overall, the preference for all calcium-rich foods was positively correlated to their intake frequency (P<0.05). Nutrition education experience and the recognition of the need for such education were positively correlated with the bone health-related nutrition knowledge score (P<0.05). In conclusion, bone health-related nutritional knowledge can affect calcium-related dietary behavior and increase the intake of calcium-rich food of 20~30-year-old women and this can contribute to the prevention of osteoporosis. To improve bone health-related nutritional knowledge among young women, it may be important to provide nutrition education.
Objectives: The present study aimed to investigate high school students' sugar intake behaviors, the status of consuming sugary processed foods, the awareness of sugar, and the experience and interest in sugar-related education based on the level of sugar-related nutrition knowledge. Methods: In this study, five high schools were selected in Seoul, Korea, and a survey was conducted in 400 students on the level of sugar-related nutrition knowledge and sugar intake status. A total of 349 questionnaires were used for the final analysis. For statistical analysis, descriptive statistics was performed; a t-test, ${\chi}^2$ test, and Friedman test were used for comparative analysis. Results: The study results showed a positive association between the knowledge level of sugar and the appropriate sugar intake behavior and sugary food choices. The group with more nutrition knowledge on sugar was found to have good eating habits and to eat less sugary food. The main sources of sugar were beverages, confectionary, and bakery goods in the corresponding order, irrespective of the level of nutrition knowledge related to sugar. A significant difference was found in the groups' awareness of the sugar content of the drinks with 89.4% for the higher-knowledge group, and only 81.5% for the lower-knowledge group (p < 0.05). Results also showed that 43.9% of the higher-knowledge group and 36.4% of the lower knowledge group were interested in participating in education on sugar. Conclusions: This study result indicated the need to help adolescents to avoid excessive sugar intake from only certain favorite foods. Therefore, it is necessary to seek a systematic foundation for participatory education in order for them to maintain a low sugar intake in daily life and lead healthy eating habits by increasing their level of sugar-related information and knowledge.
Good snack consumption behaviors are important among elementary students because snack provides additional energy and nutrients and because good dietary behaviors should be formed during early stages of life. This study investigated, among elementary school students, 1) snack consumption behaviors, 2) snack-related nutrition knowledge level, and 3) relationships between snack behaviors and snack-related nutrition knowledge. A convenience sample (N = 372), drawn from 5th and 6th graders of an elementary schools in Siheung-si, Gyeonggi-do, completed a pre-tested questionnaire. More than 85% of the participants snacked more than once per week. Most (77%) had their snacks at home. Fruit and fruit juice were the most frequently consumed and the most liked snack items. Taste was the most important in choosing a snack item closely followed by health/nutrition. Snack-related knowledge level was relatively high and the participants obtained their nutrition knowledge through mass media (30.4%) and family/friends (29.0%). Snack-related nutrition knowledge level and snack consumption behaviors showed positive relationships in various areas such as choosing more nutritious snack items and checking nutrition labels. Although this study was limited by its cross-sectional study design, these positive relationships suggest that better nutrition knowledge could result in better behaviors. Results of this study indicated that factual nutritional knowledge has been well transmitted to students. Therefore, future nutrition education on snacking could focus more on providing problem-solving and operational knowledge.

Objectives: Dietary life is closely associated with dietary attitude and diet-related knowledge. Particularly, dietary habit such as sodium intake can be affected by various dietary behaviors such as food choices, dietary attitude toward salty food and a preference for salty taste. The purpose of this study was to assess sodium-related nutrition knowledge and to identify sodium-related attitude and behaviors according to the level of sodium-related knowledge of university students. Methods: Anthropometric measurements were provided by 408 students who participated in this study. The study participants answered questionnaires to provide information on general dietary behaviors, sodium-related dietary attitude and other behavioral factors. A total score of nutrition knowledge was used to categorize study participants in to two groups, namely, low level in sodium-related knowledge (LNaK) or high level in sodium-related knowledge (HNaK) and the attitude and the behaviors of students toward sodium intake were compared between these two groups. Results: The ratio of female students in HNaK group was higher than that in the LNaK group. HNaK group had a higher score in checking nutrition label of processed food than the LNaK group. Total score of sodium-related attitude and behaviors of HNaK group were 34.81 and 32.75, respectively and these scores were significantly higher than that of the LNaK group whose scores were 32.57 and 30.57, respectively. Total energy intake was not different between two groups but the intakes of calcium, vitamin B2 and folate were higher in HNaK group than in the LNaK group. Correlation analysis adjusted for age and gender revealed that total score of sodium-related nutrition knowledge was positively correlated with total score of sodium-related attitude and behaviors. Conclusions: In conclusion, students who had high level of sodium-related nutrition knowledge had desirable attitude and behaviors toward sodium intake and these results can be considered in nutrition education for university students.
Purpose: This study compares the differences in health-related factors, nutrition knowledge and dietary habits between nursing and allied health college students. Methods: Nursing students(n=499) and allied health college students(n=402) were surveyed on their health-related factors, nutrition knowledge and dietary habits. Data were collected from two universities in A city, Korea. Data were analyzed through descriptive statistics, $x^2$ distribution and t-test, $x^2$-test and Pearson correlation coefficient using SPSS 21.0. Results: The level of nutrition knowledge was higher among nursing students than students majoring in other fields. Scores regarding dietary habits were not significantly different between nursing students and other students. Conclusion: Nutritional education for college students is needed in order to improve their health. Nutritional education programs should be tailored to meet various needs of these students.
This study examined the effects of a nutrition education program on nutrition-related knowledge, eating habits, and dietary behavior. Subjects were 3rd grade elementary school students in Anyang, Gyeonggi-do. A 5-week nutrition education program was implemented to 28 children and another 26 children were included in the study as a control group. A self-administered questionnaire was used to assess the effects of nutrition education program. Mean nutrition related knowledge score was improved after education (p < 0.001). There was a significant improvement in knowledge of nutrient source (p < 0.05), role of protein (p < 0.05), food tower (p < 0.001), getting information from nutrition labeling (p < 0.05), and proper way of snacking (p < 0.001). Eating habits and self-efficacy also tended to improve by nutrition education, especially eating habit of snack and self-efficacy on balanced diet reached significant improvement (p < 0.05). Food consumption frequency was not changed significantly, only consumption of sea weeds which is considered as a reluctant food among children was increased after education (p < 0.05). In addition, the number of leftover food items and total amount of leftover at school lunch reduced significantly after education when compared with the same 10-day menu prior to education (p < 0.01). This result suggests that unbalanced dietary behavior has been changed with the nutrition education program. In conclusion, the nutrition education program was found to be effective in improving nutrition-related knowledge, eating habits, and dietary behavior.
The growing concern for poor dietary habits among adolescents has prompted many researcher to study the adolescents' knowledge and beliefs on a number of nutrition-related issues. Following that precedent, this study was conducted to evaluate the nutrition knowledge of a sample of adolescents in a middle school in Ohio. The participants were 532 students in the sixth, seventh, and eighth grades between the ages of 11 and 13 from Shawnee Middle School in Lima, Ohio. The students were asked to answer a questionnaire CANKAP (Comprehensive Assessment of Nutrition Knowledge, Attitudes, and Practices), which measured their nutrition knowledge. The CANKAP questionnaire consisted of 20 questions for sixth grade students and 25 questions for seventh and eighth grade students. Also, the participants were asked to identify their gender. According to the result, nutrition knowledge of middle school children was weak. The findings indicated that females had higher mean nutrition knowledge scores than boys in the seventh and eighth grades. There was no significant difference in the mean value of nutrition knowledge between sixth grade boys and girls.
Objectives: The purpose of this study was to examine the food allergy-related knowledge, awareness, and performance of dietitians at children's hospitals, depending on whether or not they have a clinical dietitian certificate. Methods: A questionnaire survey was administered to 41 dieticians at children's hospitals registered as a part of the Korean Hospital Association. The survey consisted of questionnaires examining general characteristics, nutritional counseling-related characteristics, and food allergy-related characteristics (food allergy-related knowledge, awareness, and performance). We examined differences according to the status of clinical dietitian certification. Results: The proportion of subjects who were holders of clinical dietitian certificates was 48.8%. There were differences between holders of clinical dietitian certificates and non-holders as follows. Regarding nutritional awareness and performance, 'needs to provide nutrition counseling in children's hospitals', 'providing nutrition counseling services in working hospitals', and 'whether there is a nutrition counseling room' scored higher among holders of clinical dietitian certificates than non-holders. Holders of clinical dietitian certificates showed higher scores for knowledge of food allergy symptoms and food allergy management than non-holders. For food allergy awareness and performance, 'self-assessment of food allergy knowledge understanding level', 'awareness of open oral food challenge (OFC)', 'recognition of the need for education and counseling on food allergy for patients / guardians', and 'food allergy related educational experience' scored higher among holders of clinical dietitians certificates than in non-holders. Conclusions: Children's hospital dietitians with a clinical dietitian certificate showed high knowledge, awareness, and performance related to food allergies. It is thus necessary to employ a clinical dietitian for food allergy management in children's hospitals. In addition, training and conservative education are necessary for the management of food allergies for children's hospital dietitians.
The purpose of this study was to investigate the relationship of body mass index with environmental and dietary factors including nutrition knowledge, and nutrition attitude of Korean adolescents. Anthropometric measurements, questionnaire responses, and 24-hour dietary records of 531 elementary, 543 middle, and 533 high school students residing in Seoul and Kyunggi-do were collected. Data was analysed using SAS computer program. The results are as follows. Mean BMI of elementary school boys was higher than that of girls. However, there were no significant differences in mean BMI between sexes both in middle and high school students. Calcium and iron consumption were lowest among elementary and middle school students, respectively when the intake was expressed as a percentage of the Korean RDA. Energy, protein, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, and vitamin C intakes(% RDA) were lowest among high school students. The factors influencing BMI of elementary students were BMI of the parents in boys, and BMI of the father in girls. In middle school students, energy intake, fathers BMI, mothers nutrition knowledge and students BMI, and nutrition knowledge were related to the obesity indices of boys, while fathers and mothers BMI were related to the mean obesity index of girls. In high school students, nutrition knowledge and mothers nutrition attitude were related to the obesity index of boys, while BMI of parents was related to the obesity index of girls. In conclusion, mothers and fathers BMI were the most common factors influencing the BMI of these adolescents. Although these results can not determine if food behaviour directly affects BMI, it may influence the BMIs of family members, and therefore nutrition education to keep normal weight and desiradle food habits should be emphasized. More systematic studies to investigate the cause-effect relations of these factors are required.
