OBJECTIVES: To evaluate the blood and urinary cadmium concentration levels of around abandoned metal mines in comparison with a control group. METHODS: Blood and urinary cadmium concentration levels were analyzed through investigations of the dietary habits and dietary water of subjects living near abandoned metal mines (exposure group) (n=190) in comparison with those living in designated control areas (control group) (n=256). RESULTS: The blood cadmium (1.93 microgram/l) and urinary cadmium (2.41 microgram/g cr) concentrations of the exposure group were significantly higher than those of the control group (blood cadmium: 1.19 microgram/l, urinary cadmium: 1.94 microgram/g cr). Both concentrations were significantly higher in vegetarians in both groups. CONCLUSIONS: The exposure group had higher blood and urinary cadmium concentrations than the control group. We attributed the elevated blood and urine cadmium levels in the abandoned mine residents to the influence of the abandoned mine sites.

This study has been performed to analyze nutrition knowledge, dietary self-efficacy and eating habits of the elementary- and middle- school students (n = 342) according to student's stage of regular breakfast or exercise. Middle school students had higher nutrition knowledge than primary school students. Total dietary self-efficacy and dietary habit scores were not different by school year and gender. Nutrition knowledge, dietary self-efficacy and dietary habit scores were positively correlated each other. By the stage of regular breakfast, the pre-contemplation stage comprised 13.6%, contemplation 2.1%, preparation 15.7%, action 11.5% and maintenance stage 59.1%. By the stage of regular exercise, the pre-contemplation stage comprised 20.9%, contemplation 7.3%, preparation 45.6%, action 9.8% and maintenance stage 16.4%. According to the stage of change, movement from the pre-contemplation and contemplation to upper stage increased the dietary self-efficacy score. Dietary habit score increased significantly across the five stages of changes. The results of this study indicate differences in stages of changes in breakfast intake and regular exercise and indicate the need for taking these phases of change into account in nutrition education.

OBJECTIVES: A higher consumption of vegetables is emphasized as the core component of most dietary guidelines. Thus, this research investigated the dietary habits and influencing factors of vegetable preferences of adolescents. METHODS: This study was conducted by using a self-administered questionnaire. 400 students from two high schools in Gyeongnam (193 boys, 207 girls) participated in the survey. The questionnaire consisted of the following variables: dietary habit, dietary action guide and factors based on Social Cognitive Theory (SCT). RESULTS: The dietary habits of subjects showed significant differences depending on whether they prefer vegetables or not. The subjects in the group who liked vegetables had better dietary habits than the other group. Also, the study determined that the most important reason for liking or disliking vegetables is due to the taste. In the practice of dietary guidelines, the group of subjects who liked vegetables followed dietary guidelines more closely than the other group (p < 0.001). When the factors based on SCT were analyzed, personal factors showed significant differences between the groups: outcome expectation (p < 0.001), self-efficacy (p < 0.001) and affective attitude (p < 0.001). Personal factors and rated vegetable preferences showed a significant correlation in multiple regression analysis (F=42.015, p < 0.001). CONCLUSIONS: These results showed that vegetable preference is associated with a key point of desirable dietary habits among subjects. In order to increase vegetable preference or consumption, it is important to focus on strengthening not only self-efficacy of students, but also affective attitude of vegetable.

PURPOSE: This study investigates the relationship among nutrition knowledge, food habit problems and dietary attitudes in nursing students. METHODS: A total of 856 nursing students participated in the study. Data was analyzed by frequencies, t-tests, ANOVA, Pearson correlation coefficients, and multiple stepwise regressions via SPSS WIN 21.0. RESULTS: The mean scores for nutrition knowledge and dietary attitudes were above average and the score related to food habit problems was high. Dietary attitudes correlated positively with nutrition knowledge, but dietary attitudes correlated negatively with food habit problems. Significant predictors of dietary attitudes included: food habit problems, interest in nutrition and health, exercise, and drinking. The regression model explained 16.4% of perceived dietary attitudes. CONCLUSION: To improve dietary attitudes among nursing students, nursing educators should develop nutritional educational intervention programs in order to promote nutrition knowledge and identify food habit problems.

This study was conducted for researching demand on dietary education of low-level elementary school students and to develop an activity based textbook and a teaching manual on the subject. For necessity of dietary education, 88.8% of subjects answered dietary education is needed. The desirable frequency of the education was once a week (65.7%). The most appropriate time for the education was "school lunch" (37.5%), "special activity" (29.9%), "regular class" (12.4%) and "after school activity" (12.1%). The most preferred educational method was "experiment and practice" (40.1%). The desirable educational materials were "computer materials" (20.7%), "actual objects" (20.1%), "videotapes" (16.5%), "photographs-pictures" (12.2%) and "fairy tales-cartoons" (12.2%). The students wanted dietary information as "cooking" (26.1%), "growth and nutrition" (23.7%) and "right food information" (20.1%). The textbook was composed of five major chapters, which were "Traditional Dietary Culture", "Food", "Dietary Habit", "Hygiene and Environment" and "Cooking". Each major chapter had five to six smaller chapters, adding up to total of 32 chapters. The textbook had fun characters, illustrations, photographs and cartoons to deliver the main theme of each chapter. The textbook was in activity format so that it coul be readily and directly used in actual classes. The teaching manual was composed of background, goals, teaching plans and teaching points. The smaller chapters had learning goals, teaching-learning resources, important points, teaching-learning processes and reference materials. Videos were produced to help cook five snacks in the cooking chapter. Also, "Healthy Song" was created to be used in classrooms. This textbook will be helpful in children's right dietary habits and growth.

This study was conducted to investigate the dietary habits and practices of mothers and their children from 3 to 6 years of age as well as the mother's attitudes about nutrition education. This study focused mainly on two areas: 1) the dietary habits and actual dietary practices of mothers and their children and 2) a mother's perception and need for nutrition education. The results of the regression analysis showed that there was a significant relationship between the dietary habits of mothers and their children's (p<0.05). There was statistical significance in total food frequency intake and the food frequency intake between the mothers and children (r=0.829, p<0.01). The results of the regression analysis showed that the mother's dietary attitude (meal regularity, meal tempo) could positively influence their children's dietary attitude (p<0.01). The mothers showed a high interest in nutrition education; 81.6% of mothers tried to apply nutrition information to their actual dietary life, 77.6% of them recognized the need of nutrition education on preschoolers' dietary life and health, and 75.2% of them wanted to participate in nutrition education program(s) for their children. The percent of mothers that wanted to be offered lectures, food practices and hand-outs were 36.9%, 18.4%, 15.5%, respectively. The combined results of this study showed that mothers sincerely recognize the need for nutrition education and they have a high and deep interest in nutrition education.

The purpose of this study is to investigate the relationship of nutritional knowledge, dietary self-efficacy and dietary behavior of nutritionist. Total 190 dieticians of middle and high schools in Daejeon metropolitan city (44.2%) and Chungnam area (55.8%) were surveyed by questionnaires. The change of dietary intakes was used as an index of dietary behavioral change, and dietary self-efficacy are categorized into 4 sub groups of general dietary habit, choice of food, environmental stimulus and emotional conditions. Overall nutritionl knowledge of school dieticians was relatively high as 80.3 score, but specific and detail knowledge about food and nutrition yet have to be strengthened. Dietary selfefficacy of 'choice of food' was the highest with 85.4 and self-efficacy of 'environmental stimulus' was the lowest with 69.7 in the subjects. There was no influence between nutrition knowledge and dietary self-efficacy of school dieticians. According to the level of dietary self-efficacy, the intake of desirable food showed no significant difference, but the intake of undesirable foods decreased as dietary self-efficacy increased (p < 0.001). In the analysis of correlation of change in intake of desirable and undesirable foods with nutrition knowledge and 4 different variables of dietary selfefficacy, a nutrition knowledge variable did not show any correlation with other variables. While, total dietary selfefficacy or each 4 sub items showed negative correlation with the intake of undesirable foods. And all 4 sub items of dietary self-efficacy could be the principal factors to constrain the intake of undesirable foods, but 2 items of dietary habits and emotional condition of 4 sub items are the factors to increase the intake of desirable food. Accordingly, it is suggested that dietary self-efficacy could be a powerful factor to induce the behavioral change of professional dieticians.

PURPOSE: This study examined the mediation effects of dietary habits, nutrient intake, daily life in the relationship between the working hours of Korean shift workers and metabolic syndrome. METHODS: Data were collected from the sixth (2013–2015) Korea National Health and Nutrition Examination Survey (KNHANES). The stochastic regression imputation was used to fill missing data. Statistical analysis was performed in Korean shift workers with metabolic syndrome using the SPSS 24 program for Windows and a structural equation model (SEM) using an analysis of moment structure (AMOS) 21.0 package. RESULTS: The model fitted the data well in terms of the goodness of fit index (GFI) = 0.939, root mean square error of approximation (RMSEA) = 0.025, normed fit index (NFI) = 0.917, Tucker-Lewis index (TLI) = 0.984, comparative fit index (CFI) = 0.987, and adjusted goodness of fit index (AGFI) = 0.915. Specific mediation effect of dietary habits (p = 0.023) was statistically significant in the impact of the working hours of shift workers on nutrient intake, and specific mediation effect of daily life (p = 0.019) was statistically significant in the impact of the working hours of shift workers on metabolic syndrome. On the other hand, the dietary habits, nutrient intake and daily life had no significant multiple mediator effects on the working hours of shift workers with metabolic syndrome. CONCLUSION: The appropriate model suggests that working hours have direct effect on the daily life, which has the mediation effect on the risk of metabolic syndrome in shift workers.
