Objectives: This study was performed to examine dietary habits, life stress, and nutrition knowledge among high school students in Gyeonggi area. Methods: A total of 431 high school students (210 males, 221 females) in Gyeonggi area participated in this study from November to December of 2011. The study was a questionnaire-based survey that included dietary habits, dietary attitudes, life stress, and nutrition knowledge. Results: Body weight, height, and body mass index were all higher in male students than in female students (P < 0.001, respectively). For dietary habits, the average score (P < 0.01) and scores for considering combination of food groups (P < 0.05), eating green and orange vegetables (P < 0.05), eating meat, fish, eggs, or beans everyday (P < 0.05), drinking milk (P < 0.001), and eating seaweed (P < 0.01) were higher in male students than in female students. For dietary attitudes, the average score (P < 0.05) and scores for the five items were significantly different between male and female students. Male students showed a significantly lower nutrition knowledge score than female students (P < 0.05). Life stress score of students largely was attributable to academic factors, and female students showed higher stress score for academic, personal, and surrounding environmental (P < 0.05, respectively) factors than male students. Dietary habit score (P < 0.01) and nutrition knowledge score (P < 0.05) in female students as well as dietary attitude score (P < 0.05) in male students were negatively correlated with life stress score. Dietary habit scores in male and female students were positively correlated with dietary attitude score (P < 0.01, respectively). Need for nutrition education was significantly higher in female students than in male students (P < 0.05). Conclusions: This study provides basic information on dietary habits, dietary attitudes, life stress, and nutrition knowledge according to sex and suggests gender-specific practical nutrition education programs to address undesirable dietary habits and attitudes in students with higher stress levels.

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.

This study compared nutrition knowledge, dietary behaviors, and checking behaviors of food and nutrition labels between Korean and Chinese university students to obtain useful data for development of an education program for healthy dietary life. The data were collected by a self-administered questionnaire in Korea and China. Frequencies, t tests, ${\chi}^2$ tests, Cronbach's ${\alpha}$, and Pearson's correlation coefficient analysis were conducted by SPSS Win. V.21.0. The levels of nutrition knowledge and dietary behaviors were not high. Korean students showed higher percentage of correct answers about nutrition knowledge and levels of dietary behaviors than Chinese students. The means of degree of checking contents of food labels were 3.46 points for Korean students and 3.11 for Chinese students. Both groups of students showed the highest degree of checking milk and dairy products. The degree of understanding nutritive component labeling of Chinese students was higher than that of Korean students. Both groups of students showed higher than normal levels of confidence about nutritive component labeling and necessity of education on food and nutrition labels. The most preferred method of education on food and nutrition labels was broadcast media for both groups of students. In addition, there were significant correlations among nutrition knowledge, dietary behaviors, checking degree of food labels, checking degree of nutritive component labeling, and experience of nutrition education.

The purpose of this study was to examine the level of concern and the level of knowledge of endocrine disruptors, and the level of dietary behaviors to decrease exposure to endocrine disruptors, to determine the factors affecting the level of knowledge and behaviors, and to assess the causal relationship between them. The data were collected from 579 adults in Seoul, Incheon, Daejeon, Daegu, Busan and Gwangju provinces. Frequencies, t tests, analysis of variance, Cronbach's alpha, Pearson's correlation coefficient analysis, multiple regression analyses, and path analysis were carried out by SPSS for Win V.18.0. The results of this study were as follows: The level of concern about endocrine disruptors was higher than the medium level. The respondents were most concerned about a container of cup ramen among products related to foods. The levels of both knowledge and behaviors in order to decrease exposure to endocrine disruptors in dietary life were not high. The factors affecting the level of knowledge of endocrine disruptors were educational level, attendance in education for endocrine disruptors, and concern about endocrine disruptors. On the other hand, sex, age, concern about endocrine disruptors, and the level of knowledge of endocrine disruptors affected the level of behaviors to decrease exposure toward endocrine disruptors. The results of the path analysis showed that educational level and education of endocrine disruptors had an indirect influence on the level of behaviors in order to decrease exposure to endocrine disruptors in dietary life. The concern about endocrine disruptors had both a direct and an indirect effect on the level of behaviors to decrease exposure to endocrine disruptors in dietary life. In addition, sex, age and the level of knowledge of endocrine disruptors directly affected the level of behaviors to decrease exposure to endocrine disruptors in dietary life.

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.

This study investigated the correlations among the health consciousness, nutrition knowledge, dietary habits and nutrition attitudes of school teachers. The subjects of this study were 75 male and 152 female leachers in elementary and middle schools in Masan city. The survey was conducted by using a questionnaire. Even though the average body mass index (BMI) and the obesity index were normal in both male and female subjects, 33.3% of the male subjects were overweight/obese, while 18.5% of the female subjects were underweight, according to the obesity index. The food components of most concern during mealtime were (in order of importance) salt, MSG and cholesterol by male subjects, and salt, fat and MSG by female subjects. The subjects considered self-relaxation as the most important factor in maintaining optimal health status, followed by resting, bathing or use ova sauna, moderation in diet, exercise, decreasing alcohol intake, and no smoking. Newspapers/magazines and TV/radio were the primary sources of nutrition and health information of the subjects. As the degree of health consciousness increased, scores of the dietary habits and nutrition attitudes increased. Nutrition knowledge scores and nutrition altitudes scores increased with subjects'increased level of perception of the importance of acquiring nutrition knowledge and nutrition information. There was a highly significant correlation between the degree of health consciousness and dietary habit score (${\gamma}$ : 0.3, p<0.001). The degree of health consciousness was also significantly correlated (${\gamma}$=0.6, p<0.001) with nutrition attitudes scores. But the correlation between the degree of health consciousness and nutrition knowledge was not statistically significant. The degree of the perception of the importance of nutrition knowledge showed a positive correlation with nutrition attitude (${\gamma}$:0.4, p<0.001) and dietary habit (${\gamma}$:0.3, p<0.001). The degree of perception about the importance of nutrition knowledge and nutrition information was positively correlated with nutrition knowledge (${\gamma}$:0.2, p<0.001) and nutrition attitudes (${\gamma}$:0.3, p<0.001).
