The purpose of this study was to evaluate the dietary attitude and food behavior of elementary, middle and high school students in Korea. The subjects in this study were 7,698 boys and girls in large cities in Korea. The questionnaire was made and distributed to the students to answer the questions. Followings are the results of this study : 1) Father and mother's average ages were 45 and 41 years old, respectively. 2) Most students thought dietary life was more important than clothing or residentary life. Dietary habits such as irregularity of meal, frequencies of skipping meal and of eating out increased in higher grade than in lower grade, and in girls than in boys. 3) Most students, especially in elementary school, recognized that their own bad dietary habbit was unbalanced diet. Irregular meal time and eating too much were also pointed out as problems by middle and high school students. 4) Most students thought that the most effective meal for health was breakfast, but they replied the tartest meal as dinner. 5) Students tended to prefer Korean style food. Cooked rice and kimchi, ramyun, and pizza were ranked the most preferred food when they were hungry. 6) Elementary school students ate meals more regularly than higher grade students, and girls ate meals more regularly than boys. 7) Skipping rate of breakfast was higher than that of lunch or dinner, and the percentage of meal skipping students was increasing with grade elevation. No time to eat or eating between meals was the reasons of irregular meal time. 8) Frequency of dining with family was decreased, but frequency of eating out with friends was increased with increasing grade. The gravity of dining out is increasing rapidly in Korean adolescents. Therefore, nationwide nutrition education policy is necessary to constitute a right dietary environment and a desirable dietary altitude.

This study was performed to investigate the effectiveness of nutrition education and exercise intervention in a weight management program. The subjects were 24 obese women whose body mass index (BMI) was over $25kg/m^2$. Nutrition education was given once a week, and subjects did swimming three times a week. The program lasted for 12 weeks. Nutrient intakes were assessed by 24 hour recall method. Also food habits, dietary behavior and nutrition knowledge were examined by self-administered questionnaires before and after the weight control program. Height, weight, body composition and blood composition were measured before and after the weight control program. Over the 12 weeks in the weight control program, body weight significantly decreased from 69.7kg to 65.8kg(p<0.001). Body fat and BMI also significantly decreased(p<0.001). Cholesterol level significantly decreased at p<0.001 and blood sugar also significantly decreased (p<0.05). After taking nutrition education, dietary behavior and nutritional knowledge scores increased, energy intakes decreased from 1426.5kcal to 1408.5kcal and calcium from animal products significantly increased(p<0.05). A negative correlation between nutrition knowledge and BMI(r=-0.42) existed(p<0.05). A negative correlation of eating behavior with EER(r=-0.48) showed(p<0.05). We concluded that combined nutrition education and exercise was an optimal method for reducing weight.

Korean's intake of Han-Sik (Korean food) has gradually decreased. The aim of this study was to assess needs for a dietary education program focused on increasing Han-Sik intake (Han-Sik program) in children and adolescents according to education level. A total of 2,858 child and adolescents (elementary students 30.1%; middle school students 34.8%; high school students 35.1%) were recruited in 2015 and 2016, and questionnaires were conducted by self-administration. There were significant differences in diet and health information sources, Han-Sik proportion in school meals, experience of Han-Sik nutritional program, and preference for program composition by education level (p<0.001). The Han-Sik proportion in school meals was 87.4% of the total, which was significantly lower in high school students than in elementary students (p<0.001). The percentage of high school students with Han-Sik nutritional program experience (25.1%) was twice as low than that of elementary students (55.7%) (p<0.001). In addition, the percentage of students with Han-Sik nutritional program experience who responded "The Han-sik program is needed" was significantly higher than those who responded "It is not needed" (p<0.001). The most preferred content was 'Han-Sik cooking training' in all students. In conclusion, differences in needs for Han-Sik program by education level should be considered to develop the Han-Sik program for all education levels to increase Han-Sik consumption and formation of healthy eating habits.

Background: Colorectal cancer (CRC) is one of the most common cancers worldwide. This study aimed to investigate the interaction between the presence of a polymorphism of the XRCC1 gene and known risk factors for colorectal cancer in Thailand. Materials and Methods: A hospital-based case-control study was conducted in Thailand. The participants were 230 histologically confirmed new cases and 230 controls matched by sex and age and recruited from the same hospital. Information about demographic characteristics, life style, and dietary habits was collected using structured interviews, and blood samples were taken which were used for the detection of a homozygous and heterozygous polymorphisms of XRCC1. Associations were assessed using multiple conditional logistic regression. Results: In the univariate analysis, factors found to be significantly associated with an increased risk for CRC were the presence of the XRCC1 AA homozygote (OR= 4.95; 95% CI: 1.99-12.3), a first degree family history of cancer (OR= 1.74; 95% CI: 1.18-2.58), and a high frequency of pork consumption (OR= 1.49; 95% CI: 1.00-2.21). Intakes of fish fruit and vegetables appeared to be protective factors, but the associations were not statistically significant. In the multivariate analysis only the XRCC1 AA homozygote polymorphism and a family history of cancer emerged as risk factors (OR= 4.96; 95% CI: 1.90- 12.95 and OR=1.80; 95% CI: 1.18-2.72, respectively). Conclusions: While the XRCC1 AA homozygote and a family history of cancer were found to be associated with an increased risk of CRC, none of the dietary intake variables were clearly identified as risk or protective factors. There is a need for further research to determine the reasons for this.

Purpose : This study is descriptive research that confirms regularity of breakfast and related factor. Methods : The duration for investigation took place from April to May 2007 and 550 middle students of 6 middle school who lived in G city participated in investigation. The contents of the questionnaire consist of general trait, diet trait, life pattern and health state. Results : The significant variables of regularity of breakfast habit have some gender differences. For male students, recognition of importance of the breakfast, breakfast preparer, spare time before attendance and one's parents' breakfast habit are significant variables. On the other hand, for female students, recognition of importance of the breakfast, breakfast preparer and an income level are significant variables(p<.05). For male students, the cross ratio has 3.52 for recognition of importance of breakfast, 2.72 for one's parents' breakfast habit, 2.05 and 3.13 when one's mother prepare breakfast. For female students, the cross ratio is 3.24 score when one's mother prepare breakfast. Conclusion : The regularity of breakfast habits is related to recognition of importance of breakfast, mother's breakfast preparation and his or her parents'breakfast habit. It is necessary to propose the importance of breakfast to improve the regularity of breakfast habit and concern of parents for breakfast.

Health can be maintained and promoted by pursuing a healthy lifestyle. A healthy lifestyle implies keeping healthy habits such as regular exercise, a balanced diet, weight control, and stress management etc. The objectives of this study are: (1) To find out patterns in the lifestyle and health status of high school students. (2) To analyze the factors that affect a healthy lifestyle. (3) To compare the level of understanding of a healthy lifestyle and its practice between male students and female students. The study population wag 388 high school students. The data was analysed through a % total, a $X^2$ test, and a multiple classification analysis. The lifestyle assessment questionnaire was devided into ten sections. The results are as follows; (1) There was a positive correlation between health status and a healthy lifestyle. (2) There existed strong positive correlations between independent variables (age, group) and dependent variable (nutritional practices, physical activity, stress management, serve of purpose). (3) The level of understanding of a healthy lifestyle was not high for most of the students. Female students showed a higher understanding than male students in nutrition practice, while male students group showed a higher and under standing than female students for physical activity. The other result were similar in their practice of a healthy lifestyle. With all these above considerations, the level of understanding and practice of a healthy lifestyle in students was not higher than the adult group. Students should have more educational opportunities and take a more systematic education in practicing a healthy lifestyle.

The purpose of this study was to compare dietary self-efficacy for sodium intake reduction and dietary behaviors by eating areas. Subjects (797 males and 767 females) were classified according to perceived dietary habit levels related to sodium intake (lowest: ${\leq}10$ (n=434), low: $11{\sim}{\leq}13$ (n=471), high: $14{\sim}{\leq}15$ (n=360), highest: $16{\leq}$ (n=299)) using an online survey with a sample that was geographically representative of the population. The highest group was significantly younger and had a higher student proportion than the lowest group. Dining contexts regarding home led to a significantly higher sodium intake in the highest group, but it was eating out for the lowest group. The highest group had a significantly lower intention to reduce sodium intake compared to the lowest group. In the home cooked meals, the highest group displayed a significantly lower cooking frequency, less effort with respect to a low sodium diet and cooking habits related to sodium intake as compared to the lowest group. Also, regarding eating out and food service, the highest group exhibited significantly lower efforts and dietary behaviors to reduce sodium intake than the lowest group. The dietary score for sodium reduction behavior in the highest group was significantly lower compared to the lowest group, for home cooked meals, eating out, as well as food service. Thus, dietary guidelines and nutrition education for the reduction of sodium intake by eating areas need to be developed and provided.

Stomach contents of Amblychaeturichthys hexanema and A. sciistius (Perciformes: Gobiidae) from southeastern waters off Korea were analyzed to determine dietary habits and the presence of any inter- and intra-specific partitioning of food resources. These two species were bottom-feeding carnivores that consumed mainly benthic crustaceans, and other demersal invertebrates and planktonic organisms were also important in their diets. Non-metric multidimensional scaling (nMDS) ordination and multivariate analyses based on gravimetric contributions of the different prey taxa to stomach contents revealed significant inter-specific dietary differences; i.e. partitioning of food resources between the two species. Size-related changes, however, were not significant for their diets. Differences in the types and range of prey ingested by the two species could often be related to differences in the feeding behaviors. Our results of stomach contents analyses provide clear evidence of niche segregation between co-occurring A. hexanema and A. sciistius in southeastern Korean waters, which would reduce the likelihood of inter-specific competition for food resources.

This study was intended to evaluate the overall effects of nutritional education on adults having two or more symptoms of chronic degenerative disease. A nine week nutritional education program was provided for 65 adults with chronic diseases. We assessed the changes in dietary knowledge, eating behavior and socio-psychological factors. When we evaluated the nutrient intakes of the subjects, their energy intake was 79.4% of the Korean Recommended Dietary Allowances (RDA). Their dietary intake of other nutrients was also below the RDA level except for Vitamin C. Their knowledge of dietary therapy was slightly improved after the implementing of nutritional education. The dietary behavior of ‘night snacks before sleep’was significantly improved. While the overall fear due to disease was significantly increased, self-efficacy was not improved. Self-efficacy for eating “three regular meals” and “choosing fruit, vegetable and grain” were significantly decreased. Family support for “buying food which is good for my health” was also significantly increased, whereas “advises me to eat appropriate foods for health” was decreased. Biochemical analysis indicated that blood levels of triglyceride, cholesterol and blood pressure improved after nutrition education. Therefore, we concluded that nutritional education program for people with chronic degenerative diseases could change the diet therapy knowledge, dietary behavior, and the fear due to disease, support from family and behavior intention toward the direction to improve the chronic disease condition. However, it did not improve self-efficacy. Our study also indicated that nutritional education strategies to improve self-efficacy should be an important aspect in a long term education plan for patients to establish desirable eating habits.

Background: The study investigated the influence of culturally-based health beliefs on engagement in healthy lifestyle behaviour. Specifically, the study compared levels of engagement between Western and Chinese youth in Australia and assessed the extent to which culture-specific attributions about the causes of illness, and health beliefs, predict engagement in healthy lifestyle behaviour. Materials and Methods: Ninety-four Western and 95 Chinese (N=189; Mean Age=20.8 years, SD=3 years) young adults completed an online questionnaire. Predictor variables were cultural health beliefs measured by the Chinese Cultural Views on Health and Illness scale (CCVH, Liang et al., 2008), and illness attributions beliefs measured by the Cause of Illness Questionnaire (CIQ, Armstrong and Swartzman, 1999). Outcomes variables were levels of engagement in healthy lifestyle behaviour. Results: Results indicated that Chinese participants have a significantly lower exercising rate and healthy dietary habits compared to the Western sample. Moreover, Chinese participants were found to believe more strongly than Westerners that cancer was associated with factors measured by the Traditional-Chinese-Model (TCM). Finally, the observed relationship between cultural health beliefs and physical inactivity was mediated by attributions of illness, in particular to the supernatural subscale, with the Sobel Test showing a significant mediation (z=-2.63, p=0.004). Conclusions: Mainstream approaches to encourage healthy lifestyles are unlikely to be effective when educating Chinese youth. Instead, health promotion programs should attempt to address the illness attribution beliefs and educate Chinese youth about the role of diet and exercise in prevention of diseases such as cancer.
