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).

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.

Purpose: The purpose of this study was to identify the influencing factors on eating disorders in college students. Method: A descriptive correlational study design was used. Eight hundred fifty-nine college students were administered self-report questionnaires to examine eating habits, self-efficacy, depression, and parent-adolescent communication from May to June, 2010. Collected data were analyzed by the SPSS 15.0 program for t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression. Result: The level of an eating disorder in participants was moderate and it differed by gender, major, and type of living. The eating disorder showed a significant correlation with self-efficacy (r=-.28, p=<.000), depression (r=.23, p=.001), and parents-adolescent communication (r=-.13, p=.008). Self-efficacy (8.2%) and depression (2.1%) were significant predictors to explain the eating disorder. Conclusion: This study provides comprehensive understanding of the influencing factors on eating disorders in college students. It suggests that nursing interventions to improve self-efficacy and decrease depression for management of eating disorder are needed.

BACKGROUND/OBJECTIVES: Calcium is important but deficient in diets of young adult women. This study aimed to examine if cognitive factors and eating behaviors differ according to calcium intake based on the Social Cognitive Theory. SUBJECTS/METHODS: Subjects were female college students in Seoul, Korea. Three hundred students completed the questionnaire regarding calcium intake, nutrition knowledge, outcome expectations, self-efficacy and eating behaviors. Data on 240 students were analyzed using t-test or ${\chi}^2$-test. Subjects were categorized into two groups, high calcium intake (HC, ${\geq}650mg/day$) and low calcium intake (LC, < 650 mg/day), according to recommended intakes of calcium for women aged 19-29 years. RESULTS: The LC group constituted 77.9% of total subjects. Nutrition knowledge was not different according to calcium intake. Three out of 12 outcome expectations items were significantly different between the HC and LC groups. Subjects in the HC group agreed more strongly with the practical benefits of consuming calcium-rich foods, including 'taste' (P < 0.01) and 'going well with other snacks' (P < 0.05), compared to those in the LC group. Negative expectations of 'indigestion' were stronger in the LC group than HC group (P < 0.001). Among self-efficacy items, perceived ability of 'eating dairy foods for snacks' (P < 0.001), 'eating dairy foods every day' (P < 0.01), and 'eating calcium-rich side dishes at meals' (P < 0.05) differed significantly between the HC and LC groups. Eating behaviors including more frequent consumption of dairy foods, fruits or fruit juice (P < 0.001), anchovy, seaweeds, green vegetables, protein-rich foods (P < 0.05), and less frequent consumption of sweets or soft drinks (P < 0.01) were significantly related to calcium intake. CONCLUSIONS: This study found that outcome expectations, self-efficacy in consuming calcium-rich foods, and eating behaviors are important in explaining calcium intake. Nutrition education needs to address practical benefits, reduce negative expectations of calcium-rich foods, increase self-efficacy, and modify eating behaviors contributing to calcium intake.

BACKGROUND/OBJECTIVES: This study aimed to examine differences in weight control practices, beliefs, self-efficacy, and eating behaviors of weight class athletes according to weight control level. SUBJECTS/METHODS: Subjects were weight class athletes from colleges in Gyeong-gi Province. Subjects (n = 182) responded to a questionnaire assessing study variables by self-report, and data on 151 athletes were used for statistical analysis. Subjects were categorized into High vs. Normal Weight Loss (HWL, NWL) groups depending on weight control level. Data were analyzed using t-test, ANCOVA, x²-test, and multiple logistic regressions. RESULTS: Seventy-three percent of subjects were in the HWL group. The two groups showed significant differences in weight control practices such as frequency (P < 0.01), duration and magnitude of weight loss, methods, and satisfaction with weight control (P < 0.001). Multiple logistic regression showed that self-efficacy (OR: 0.846, 95% CI: 0.730, 0.980), eating behaviors during training period (OR: 1.285, 95% CI: 1.112, 1.485), and eating behaviors during the weight control period (OR: 0.731, 95% CI: 0.620, 0.863) were associated with weight control level. Compared to NWL athletes, HWL athletes agreed more strongly on the disadvantages of rapid weight loss (P < 0.05 - P < 0.01), perceived less confidence in controlling overeating after matches (P < 0.001), and making weight within their weight class (P < 0.05). HWL athletes showed more inappropriate eating behaviors than NWL athletes, especially during the weight control period (P < 0.05 - P < 0.001). CONCLUSIONS: Self-efficacy was lower and eating behaviors during pre-competition period were more inadequate in HWL athletes. Education programs should include strategies to help athletes apply appropriate methods for weight control, increase self-efficacy, and adopt desirable eating behaviors.

Objectives: Eating self-efficacy is an important predictor of successful weight control behaviors during obesity treatment. The Weight Efficacy Life-Style Questionnaire (WEL) is an internationally used measure of eating self-efficacy. The objective of this study was to develop the Korean version of WEL (K-WEL) and verify face validity. Methods: According to previously published guidelines, the cross-cultural translation was conducted through organizing the expert committee, translation, back-translation, synthesis, grammar review, and final synthesis. Following the translation of the WEL into Korean, face validity was performed for 35 subjects. Results: After all the versions of the questionnaire were examined, the translated WEL questionnaires were finally synthesized and licensed by the developer in writing. Regarding the translated WEL questionnaires, seven out of 35 subjects (20%) offered ideas about ambiguous expressions in them. All four points indicated in the face validity verification were additionally modified for greater clarity and understanding. Conclusions: We developed the Korean version of WEL and completed face validity. In future research, it would be necessary to provide further study on the reliability and validity of the Korean version of WEL.

Compliance with food group and nutrient recommendations, and self-efficacy, stage of change, perceived barriers and benefits for healthy eating were assessed among a convenience sample of college students majoring in health-related disciplines. Dietary and psychosocial data were collected using three-day food records and scales, respectively. Means (SD), frequencies, and percents were calculated on all data, and logistic regressions were used to determine whether any of the psychosocial correlates predicted the stage of change for healthy eating. Noncompliance with food group recommendations ranged from 53% for the meat/meat alternates group to 93% for the vegetables/juice group, whereas noncompliance with nutrient recommendations ranged from 26% for cholesterol to 99% for potassium. A majority of students (57%) self-classified in the preaction and 40% in the action stages of change for eating healthy. The students' self-efficacy to eat healthy was highest in positive/social situations and lowest when experiencing emotional upset. The most important perceived barrier to healthy eating was that friends/roommates do not like to eat healthy foods, and the most important perceived benefit was that eating healthy foods provides the body with adequate nutrients. The difficult/inconvenient self-efficacy subscale predicted the stage of change for healthy eating. These students would benefit from interactive learning opportunities that teach how to purchase and prepare more whole grain foods, fruits, and vegetables, enhance their self-efficacy for making healthy food choices when experiencing negative emotions, and overcome perceived barriers to healthy eating.

Background/Objectives: The purpose of this study is to investigate the effects of eating habits and self-efficacy on health promotion behavior and to improve the quality of life in each life cycle. Methods/Statistical analysis: This study is a narrative research study for nursing students at university B in C city. The data were analyzed by SPSSWIN 18.0, t-test, ANOVA and bonferroni post test, Pearson correlation coefficient calculation and multiple regression analysis. Findings: Health promotion behaviors were positively correlated with eating habits and self-efficacy. Multiple regression analysis showed that 53.8% of the parents, caregivers, health status, eating habits, and self - efficacy of the nursing students showed the health promotion behaviors of the nursing students. The higher the self-efficacy(t=6.06, p<.001), the better the health-promoting behaviors(t=3.28, p=.001). Application/mprovements: Development of programs for strengthening health education and self-efficacy is required for proper eating habits and health promotion.

BACKGROUND/OBJECTIVES: This study examined the differences in psychosocial factors and eating behaviors by the stages of change (SOC) in nutrition management among elementary and middle school athletes. SUBJECTS/METHODS: Subjects were young athletes recruited from the athletic clubs of 10 organizations. Subjects responded to a survey questionnaire, and data on 167 athletes were analyzed. Subjects were grouped into the pre-action or action stage in nutrition management. The χ² test, t-test, analysis of covariance, and correlation analysis were used in data analysis. RESULTS: Athletes in the action stage (62.3%) compared to the pre-action stage, showed a higher self-efficacy (P < 0.01), and felt more confidence in performing specific eating behaviors (P < 0.05 to P < 0.01). Those in the action stage had more favorable beliefs regarding nutrition (P < 0.001) and agreed less strongly on the specific misconceptions/disadvantages of nutrition (P < 0.01) than those in the pre-action stage. Eating behaviors (P < 0.001) and subscales of the eating behaviors (P < 0.05 to P < 0.01) also differed significantly by the SOC group. Place of eating dinner (P < 0.05) and the person who prepares dinner (P < 0.05) showed significant differences by the SOC group. The relationship of self-efficacy, beliefs regarding nutrition, and eating behaviors to the SOC differed by sports type. Beliefs for football athletes, self-efficacy, and beliefs for baseball athletes were correlated significantly with the SOC, whereas all 3 variables were related to the SOC for handball and other athletes. CONCLUSIONS: This study showed differences in psychosocial factors and eating behaviors between the pre-action and action stages. Nutrition education should include strategies to help young athletes modify their beliefs, mainly misconceptions/disadvantages of nutrition, increase self-efficacy, and adopt specific and desirable eating behaviors. Nutrition education might employ different strategies considering the sports type that student-athletes participate.

This study was designed to examine nutrition label use, self-efficacy, snacking and eating behaviors of middle school students, and to investigate if these characteristics were different by nutrition label use. A cross-sectional survey was conducted to 348 middle school students in Kyunggi, Korea. About a third of subjects read nutrition labels when they purchased snacks/packaged foods. Most nutrition label users were interested in reading information on calories, fat and trans-fat. Self-efficacy of eating/selecting snacks or general nutrition behavior was moderate (mean score: 44.4 out of 60), with significantly higher score in nutrition label users compared to nonusers (p < 0.001). Nutrition label users felt more confident in 9 items out of 15 items of self-efficacy, such as "taking fruits instead of cookies/candy for snack" (p < 0.001), "choosing milk instead of soft drink" (p < 0.01), "not having snacks after dinner" and "avoiding processed foods for snacks" (p < 0.05). Subjects had snacks 1.3 times a day, and nutrition label nonusers consumed snacks more frequently than the counterparts (p < 0.01). About 55% of nutrition label users and 64.7% of nonusers mainly purchased snacks for themselves (p < 0.05). Commonly purchased snacks by adolescents were ice cream, cookies/chips, breads and ramen. Major considerations in purchasing snacks were taste (46.9%) and price (34.6%). In selecting snacks, the influence of friends and parents was greater than the other sources. Based on eating frequency of snacks, nutrition label users were more likely to consume healthy snacks, such as fruit juices, vegetables, milk, yogurt, and potato/sweet potato than nonusers (p < 0.05). Eating behaviors measured by 15 items scored 33.6 out of 45. Nutrition label users showed better eating behaviors, such as "eating meals slowly", "eating foods cooked with plant oil", and "eating out less frequently" (p < 0.05). Study results showed that majority of adolescents did not read nutrition labels, selected snacks for themselves and had somewhat unhealthy foods for snacks. This study also showed the differences in self-efficacy, snacking and eating behaviors between nutrition label users and nonusers. In nutrition education, it is necessary to stress the importance and skills for reading nutrition labels. It is also needed to help adolescents to select healthy snacks and have desirable eating behaviors, as well as increasing self-efficacy.
