Purpose: The purpose of this descriptive study was to identify gender differences in predictors on dietary self-efficacy in fifth and sixth grade elementary school children. Methods: The data were collected by a questionnaire given to the 408 children between June 7 to June 17, 2011. Descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and stepwise multiple regression were used to analyze the data. Results: There were gender differences in dietary self-efficacy, exercise self-efficacy, dietary practice and depression. Dietary self-efficacy had a significant positive correlation with exercise self-efficacy and dietary practice and negative correlation with depression for both girls and boys. The predictors of dietary self-efficacy for boy were exercise self-efficacy and dietary practice, these factors explained 37.1% of the total variance. In girls, exercise self-efficacy and dietary practice were significant predictors and explained 38.7% of dietary self-efficacy. Conclusion: Based on the finding of this study, it is needed to develop a nursing intervention for dietary self-efficacy in elementary school children including to promote exercise self-efficacy and dietary practice.

The purpose of this study was to determine the relationship between children's dietary self-efficacy, general characteristics and mother's parenting self-efficacy among elementary school students. Mother's parenting self-efficacy was significantly higher as parents' educational levels increased (p<0.001), as family monthly income level increased (p<0.001), and when father's job was professional or managing work (p<0.001). Children's dietary self-efficacy was meaningfully higher when parents' educational levels were higher (p<0.01), and family income level was higher (p<0.01). Mother's parenting self-efficacy showed a correlation with children's dietary self-efficacy (p<0.001). All factors comprising parenting self-efficacy, such as 'general parenting self-efficacy' (p<0.001), 'healthy parenting self-efficacy' (p<0.001), 'communication parenting self-efficacy' (p<0.001), 'educational parenting self-efficacy' (p<0.001), and 'control parenting self-efficacy' (p<0.001) showed correlation with children's dietary self-efficacy. It is suggested that in order to improve children's dietary self-efficacy and mothers' parenting self-efficacy, families, schools, and communities must put forth a concerted effort. By complementing existing nutritional programs focusing on nutritional knowledge, one can develop a education program and social support to enhance children's dietary self-efficacy and mothers' parenting self-efficacy.

The purpose of this study was to develope nutritional teaching materials and programs for childcare major students by determining interrelations between nutritional knowledge, dietary habits and dietary self-efficacy. Out of 400 questionnaires distributed to the students majoring in childcare in Daegu, 354 were analyzed by SPSS WIN 12.0 program. The results were summarized as follows. Childcare major students' distributions of nutritional knowledge, dietary habits and dietary self-efficacy were approximately all middle levels. Nutritional knowledge scores were influenced by age and self-assessment of health. Childcare major students' dietary habits were influenced by age, the degree of satisfaction of diet, and the degree of interest in diet. Dietary self-efficacy of childcare major students was influenced by gender, satisfaction of diet, whether or not they were on a diet, recognition of the need for nutritional knowledge, and the degree of interest in diet. Nutritional knowledge and dietary habits were positively correlated with dietary self-efficacy of childcare major students. In short, childcare major students with higher nutritional knowledge scores had higher dietary self-efficacy. Further, childcare major students who had a regular diet and balanced dietary habits had stronger dietary self-efficacy.

The purpose of this study was to identify the relationships of optimistic bias about gastric cancer, self-efficacy of healthy dietary behavior and unhealthy dietary habit in Korean adult men. The subjects were 394 men aged from 20 to 64 who lived in Seoul, Kyonggi Do, Kwang-Ju, Jeonnam Do. Data was collected by questionnaire surveys using convenient sampling. The instruments used for this study were extracted and modified from Lee's(2003). The collected data was analyzed using descriptive statistics, Pearson correlation coefficient, and stepwise multiple regression with SPSS/PC 10.0 version. Unhealthy dietary habit in adult men indicated a significantly negative correlation to optimistic bias about gastric cancer(r=-.159, p=.002) and self-efficacy of healthy dietary behavior(r=-.470, P=.000). The most significant predictors influencing unhealthy dietary habit in adult men were age and self-efficacy of healthy dietary behavior. The variance explained was about 24%. These results suggested that men of young age and lack of self-efficacy of healthy dietary behavior are likely to have unhealthy dietary behavior. Therefore, considering age and facilitating self-efficacy are needed in nursing education and intervention for dietary habit change.

Purpose: The study was to test the effects of nutrition education program changing the dietary self-efficacy and dietary practice of elementary school children. Method: The study was designed as a nonequivalent control group pretest-posttest design. The subjects of the study were 70 boys and girls in the fourth grade of elementary school in Seoul. They were devided in two groups evenly : control group and treatment group. The control group participated in the nutrition education with 4 sessions for 4 weeks. data were collected by self-reported questionnaires(dietary self-efficacy and dietary practice) from the 28th of August to the 10th of October. 200l. Result: 1. A hypothesis that 'the elementary school children who participated in the nutrition education may get higher points on dietary self-efficacy than the elementary school children who did not participated' has been adopted(t=-6.36. p<001). 2. A hypothesis that 'the elementary school children who participated in the nutrition education may get higher points on dietary practice than the elementary school children who did not participated' has been adopted(t=-5.03. p<001). Conclusion: The nutrition education is an effective nursing intervention strategy for elementary school children by supporting them form positive dietary self-efficacy and improve dietary practice.

This study was made to provide basic materials required to develop the program for desirable change of eating behavior which might be regarded as the aim of nutrition education. In this study, the relationship between the factors known to be affecting eating behavior like nutrition knowledge and dietary self efficacy was examined with high grade elementary students in Gangwon Province. The results are as follows; First, positive relationship was observed with significant difference(p<0.001) in the relationships between eating behavior and dietary self efficacy(r=0.465), between nutrition knowledge level and eating behavior(r=0.216) and between nutrition knowledge level and dietary self efficacy(r=0.312). Second, the ratio explaining the effect of dietary self efficacy and nutrition knowledge on eating behavior was 22.3%, and it affected in the order of significance level such that dietary self efficacy(p<0.001) and nutrition knowledge level(p<0.05). Third, the level of desirable eating behavior was consistent with the level of nutrition knowledge. And the scores of nutrition knowledge were $28.97{\pm}4.66$ for 'poor' group, $30.01{\pm}3.85$ for 'normal' group, $31.13{\pm}3.94$ for 'good' group and $31.75{\pm}4.10$ for 'excellent' group. When the scores of eating behavior was considered in accordance with the level of nutrition knowledge, there was difference between the groups with poor and normal scores and the groups with good and excellent scores(p<0.001), however, there was no difference between poor and normal group, and between good and excellent group. Fourth, it was found that dietary self efficacy affected the eating behavior level by level. The eating behavior score was $23.82{\pm}5.25$ for the poor dietary self efficacy group, $26.88{\pm}4.00$ for the normal group, $30.27{\pm}3.66$ for the good group and $32.81{\pm}3.79$ for the excellent group. It showed that as the degree of dietary self efficacy increased the degree of eating behavior increased in all four groups (p<0.001).

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.

The slimness favored trend made students shape up body image by weight control using restrained eating. Many students especially female ones tend to be in eating disorder status. The aim of this study was to find the relation between weight, eating habits and dietary self efficacy in the selected middle school girl students group with high risk eating disorder (7.9%) and the one with low risk eating disorder (24.1%). This study was conducted by EAT-26 questionnaire method and all the data was analyzed by SAS (Statistical Analysis System) program. The results were as follows; The physical condition of eating disorder students (159.5cm height, 50.7kg weight and 97.4% PIBW) was higher and bigger than that of normal students(158.2 cm, 47.2 kg, and 92.6% PIBW). Weight control experience in the high risk group (69.4%) was significantly more frequent than normal group (p<0.001). The gap between actual body weight and desired weight was higher in high risk eating disorder group than in normal group (p<0.001). Dietary self-efficacy score of middle school female students in the high risk eating disorder group was high when they were in temper, in confusion, and after argument. However, when they were in cooking (p<0.01), with friends (p<0.05), in assembling dishes (p<0.01), and with family (p<0.05) the dietary self-efficacy score of high risk group was lower than that of normal group. In the high risk eating disorder group, eating speed was often faster (p<0.05) and overeating rate (p<0.01) was higher than in normal group. In general, EAT-26 score was correlated positively with gap weight, but negatively correlated with dietary self efficacy score(p<0.01). Gap weight and dietary self efficacy were significantly different in normal group. however, there was no relation in high risk eating disorder group. Under the circumstance of high risk eating disorder, as weight and dietary self efficacy did not affect the relation with eating disorder score, when it is determined as eating disorder some other factors besides weight and diet self efficacy seem to affect the eating disorder score. In conclusion, the factors related with eating disorder were gap weight and some items of dietary self efficacy. Thus, correct understanding of healthy weight and dietary self efficacy enhancement require the development of nutrition education contents and the practice of 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 self-efficacy 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 self-efficacy, a nutrition knowledge variable did not show any correlation with other variables. While, total dietary self-efficacy 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 was carried outto compare dietary self-efficacy, obesity stress, and obesity-related quality of life (OQOL) according to BMI and stages of change in vegetable consumption. Methods: A convenience sample of 326 nursing students agreed to complete a questionnaire. Data were collected from October 7 to October 18, 2013. Results: Obesity stress and obesity-related quality of life were significantly different according to BMI. Dietary self-efficacy showed a significant difference between the pre-contemplation/contemplation stage, preparation stage, and action/maintenance stage (F=50.18, p<.001). With obesity stress, there was a significant difference between the PC/C, P, and A/M stages (F=17.63, p<.001). Dietary self-efficacy had a positive correlation with OQOL (r=.11, p<.001) and a negative correlation with obesity stress (r=-.14, p=.012). And obesity stress had a negative correlation with OQOL (r=-.45, p<.001). Conclusion: These findings emphasize that nutritional-intervention programs for changes in behavior during the PC/C and P stages of change in vegetable consumption need to develop strategies to enhance dietary self-efficacy for nursing students.
