The objectives of this study were to identify dietary patterns of Korean middle school students and to investigate the characteristics of dietary intake of subjects with different dietary pattern. Three-day diet records were obtained from 163 male and 155 female 7th graders in Seoul, Korea. Food items from the diet records were aggregated into 22 food groups before subjected to factor analysis. Four dietary patterns emerged from factor analysis with different factor score. Cluster analysis using factor score classified subjects into three groups named 'Traditional' (n = 42), 'Westernized' (n = 135), and 'Intermediate' (n = 145). Major nutrient intake and dietary quality assessed by NAR (Nutrients Adequacy Ratio), MAR (Mean Adequacy Ratio), DDS (Dietary Diversity Score), and DVS (Dietary Variety Score) of the three groups were compared. Mean energy intakes of three groups were 1783, 1916, 1578 kcal in Traditional, Westernized, and Intermediate diet group respectively. Differences in nutrient intake of the groups were significant in all nutrients except vitamin B$_1$. Percent energy from fat was significantly higher in Westernized and Intermediate diet group, and cholesterol intake of Westernized diet group was higher than 300mg. NARs of most nutrients were higher in Traditional and Westernized than Intermediate diet group except vitamin E. Traditional and Westernized diet groups had the highest MAR of fourteen nutrients. DDS was the highest in Westernized and DVS was the highest in Traditional and Westernized diet group. Traditional diet groups had 22％ of energy consumption from breakfast, significantly higher than other diet groups. In conclusion, these results suggest that Korean teenagers with Traditional diet pattern have lower diet in ％ energy from fat, diversity of food and regularity of meals. Future studies need to focus on the relationship between dietary patterns and health status of Korean teenagers.

Objectives: The prevalence of hypertension in Korean rural elderly was significantly higher than that of the general population. Determining the potential risk factors of hypertension would be useful for managing and improving the treatment and prevention of hypertension in rural areas. Methods: We studied 336 elderly individuals 110 males, 226 females) aged between 65 years and 95 years residing in the rural area, S-gun Jeonbuk. Health-related habits, frequency of intake of food groups, nutrient intakes, anthropometric and biochemical measurements were assessed. Subjects were defined as hypertensive if SBP was ${\geq}140mmHg$ or if DBP was ${\geq}90mmHg$ or take an antihypertensive drug. Results: The rate of prevalence of hypertension in the study group was 51.8% (male 40.0%, female 57.5%). The risk of occurrence of hypertension was higher among females (OR, 1.98), 75 years old or older (OR, 1.62), BMI ${\geq}25kg/m^2$ (OR, 2.84), acceptable range (upper end) of body fat (OR, 2.29) and unhealthy (too high) range of body fat (OR, 3.28), hypertriglyceridemia (OR, 2.17) and hypercholesterolemia (OR, 5.42), low protein intakes (OR, 1.78). However, health related habits, frequencies of intake of food groups and most nutrient intakes except for protein did not show any significant relationship with the occurrence of hypertension. Conclusions: To reduce the risk of occurrence of hypertension among elderly individuals in rural areas, it is needed to avoid increase of body fat, 25 or higher BMI ($kg/m^2$) and hyperlipidemia and low intake of proteins.

This study was designed to develop, implement and evaluate a nutrition education program for elementary school children. Subjects consisted of 47 children in the 6th grade in Seoul, Korea. They received five sessions of nutrition education from June to July, 1999. Topics for nutrition education included function of nutrients, food sources of nutrients, balanced diet, meal planning, and adequate energy intake. Each session lasted 40 minutes. To evaluate program effectiveness, one group pretest-posttest design was used. Subjects were given a pretest and a posttest on nutrition knowledge, eating attitudes, eating behavior, and dietary intake. All data were statistically analyzed mainly using the paired t-test and $\chi$$^2$-test. There was a significant difference between pretest and posttest score on nutrition knowledge(p<0.001), subscales of nutrition knowledge including food sources of nutrients, function of nutrients, and balanced diet(p<0.001). These changes in nutrition knowledge were also shown both in boys(p<0.001) and in girls(p<0.001). Eating attitudes, subscales of eating attitudes, and eating behavior were not significantly changed after nutrition education, although some changes were observed in these variables. Dietary intakes were not significantly were not significantly changed after nutrition education for all subjects ; however, different patterns in dietary intakes were observed when examined by sex. There was an increase in nutrient intakes among boys, while there was a significant decrease in nutrient intakes among girls after program implementation. Especially, it was noted that girls had diets deficient in iron, calcium, and vitamin A, even after nutrition education. It was concluded that a five-week nutrition education program can improve nutrition knowledge or some dietary intake, but this might not be enough to induce changes in food attitudes, eating behavior or dietary intakes. It might be necessary to incorporate diverse approaches, targeting sub-groups of children, and follow-up in nutrition education for elementary school children.

BACKGROUND/OBJECTIVES: The aim of this study was to analyze the factors related to sarcopenic obesity among the elderly in South Korea. SUBJECTS/METHODS: A total of 3,367 elderly (${\geq}65years$) from the Korea National Health and Nutrition Examination Survey (2008-2011) were included in this analysis. The subjects were assessed to determine their sarcopenia and obesity status. Sarcopenia was assessed by determining their appendicular skeletal muscle mass (ASM). Obesity was defined by the waist circumference. An association of sarcopenic obesity and the related factors was analyzed using multiple logistic regression models. RESULTS: The risk of sarcopenic obesity of the subjects was decreased by active physical activity. After adjusting for age, smoking, and alcohol consumption, the risk of sarcopenic obesity in men of the highest level group (Q4) decreased by 45% (OR = 0.550, 95% CI = 0.334-0.905, P trend 0.018) compared to that in the reference group (Q1). Among the women, the risk of sarcopenic obesity in the Q3 and Q4 groups decreased by 29.0% (OR = 0.710, 95% CI = 0.512-0,984) and 56.7% (OR = 0.433, 95% CI = 0.281-0.668), respectively, compared to that in the Q1 group (P trend < 0.001). The mean daily energy intake was higher in the non-sarcopenia group than in the sarcopenia group. The risk of sarcopenic obesity in subjects not meeting the recommended intakes of energy, riboflavin, and vitamin C increased significantly by 25.4%, and 36.6%, and 32.6%, respectively, compared to that in the subjects meeting the recommended nutrient intake. CONCLUSION: Active physical activity as well as an adequate intake of energy and some vitamins might be negatively associated with the development of sarcopenia and sarcopenic obesity in the elderly.

Cancer is the first leading cause of death in Korea and the second leading cause of death in the USA. There is extensive research into prevention of cancer and the support of oncology patients with diet or dietary supplements. In vitro and in vivo animal studies have indicated that antioxidants, including beta-carotene, alpha-tocopherol, and ascorbic acid, can yield anti-cancer effects in addition to providing protection against oxidative damage. Although many observational studies have shown that consuming fruits and vegetables can reduce the risk of some cancers, the results of several large-scale human intervention trials testing the benefits of a single or combined higher-dose of individual micronutrients have been inconsistent. Cancer can cause profound metabolic and physiological changes which may affect patients' nutrient requirements. Although the optimal route of nutrient delivery is through diet, cancer patients often suffer symptoms that disrupt their food intake, including anorexia, premature satiety, altered taste and smell, and changes in bowel mobility. In particular, micronutrient deficits can slow postoperative healing, contribute to depression symptoms, and decrease immune competence. Cancer patients are generally motivated to take dietary supplements to improve responses to treatment and quality of life. The Physician's Health Study II (PHS II) randomized controlled trial reported recently that daily multivitamin supplementation significantly, albeit modestly, reduced the risk of total cancer. Although evidence of multivitamin use benefits is limited in cancer patients, taking dietary supplements with constituents in the range of the recommended daily allowance according to the Dietary Reference Intake (DRI) recommendation is generally considered to be safe.

Recently the Ministry of Health and Welfare, Republic of Korea, announced the “Dietary Guidelines for Korean Adults (DGKA)”, which includes ten Dietary Goals, six Dietary Guidelines, and twenty-three Action Guidelines. DGKA are developed as the revision of the 2003 Dietary Guidelines for Koreans, targeting adult population. Dietary Guidelines are developed for general purpose as well as for different age groups. They are revised periodically to accommodate changes in diet and health problems of the population. The process of developing new DGKA can be summarized as 1) selection of focus areas, 2) analysis and review of available data for each area selected, and 3) derivation of guidelines based on the analyzed data, and 4) finalizing the guidelines after open discussions among the experts and general public. Five focus areas were selected by examining the Nutrition Goals of the Health Plan 2010 of Korea, soliciting proposals from the experts in the related fields, and reviewing existing and international guidelines. Five areas selected were 1) adequate intake of nutrients and foods, 2) balance of energy intake and physical activities, 3) alcohol intake, 4) food security and nutrition service, and 5) food safety. Adequacy of nutrient and food intakes of the Korean adult population was assessed using 2005 Korea National Health and Nutrition Examination Survey (KNHANES) data. Newly developed Dietary Reference Intakes for Koreans were used as reference values to assess the prevalence of inadequacies and excesses in nutrient intakes. Energy balance was examined with energy intake of 2005 KNHANES survey and results of physical activity questionnaire in the survey. Alcohol intake was also examined using 2005 KNHANES results of dietary intakes as well as the results of questionnaire survey on alcohol intakes. Food security, nutrition services, and food safety were analyzed using various government data and published results on the issues. Ten Dietary Goals and six Dietary Guidelines were developed after data analysis and were subjected to reviews of experts and general public. The final DGKA are: 1) Eat a variety of foods from each food group, 2) Increase physical activity and maintain healthy weight, 3) Eat proper amount of clean foods, 4) Avoid salty foods and try to eat foods with bland taste, 5) Avoid foods with high fat contents and deep-fried foods, and 6) When you drink alcohol, limit the amount. Twenty-three action guidelines are developed in order to achieve these guidelines in actual diet and life among the population. The government is disseminating the guidelines with “337” slogan and emblem. “337” indicates everyone should practice “3” guidelines of promoting good eating practice, “3” guidelines to limit or decrease in your diet, and you should practice them for “7” days a week. The guidelines will be useful in promoting healthy food habits and good nutritional status which will result in decrease nutrition related health problems in Korea.

Purpose: This study was conducted to investigate the nutrient intake and food variety in Korean adolescents. Methods: We analyzed 1,555 adolescents aged 12 to 18 years using data from the combined 2010~2012 KNHANES (Korean National Health and Nutrition Examination Survey). In this study, subjects were divided according to age group (12~14 y, 15~18 y). The nutrient intake, ND (nutrient density), food intake and food score from each food group, variety and food intakes of meals, DDS (dietary diversity score), and GMVFDO (grain, meat, vegetable, fruit, dairy and oil food group) were analyzed using data from the 24-recall method. Results: The results showed that the 15~18 age groupskipped breakfast significantly more often than the 12~14 age group (p < 0.0001). The 15~18 age group consumed significantly higher quantities of fat per 1,000 kcal compared to the 12~14 age group (p = 0.0069). Regarding food variety, the 15~18 age group showed a significantly higher intake (p < 0.0001) and score (p < 0.0001) from beverages than the 12~14 age group, whereas the 15~18 age group showed a significantly lower intake (p = 0.0084) and score (p = 0.0253) from milk than the 12~14 age group. In addition, DDS in the 15~18 age group (4.33) tended to be lower than that of the 12~14 age group (4.44) (p = 0.0727). Conclusion: Proper dietary management regarding meal variety is needed for the 15~18 age group, and more systematic studies to investigate the meal variety roles of adolescents are required.

The aim of this study was to examine and compare the eating habits, dietary intake patterns and nutrient intake status of children with and without atopic dermatitis by questionnaire during July, 2008. A total 388 subjects of 5th and 6th grade elementary school children (AG: atopic group, n=65, NG: non-atopic group, n=323) in Seoul and Ulsan areas participated in this study. The questionnaire included general characteristics, dietary habits, and atopy-related food frequency. One-day 24 hour recall was collected to estimate nutrient intakes of the subjects. The data were analyzed by Chi-square test for food frequency analysis and by t-test for nutrient intakes. Atopy-related foods included milk, buckwheat, beef, pork, chicken, crab, egg, mackerel, peach, and tomato. From the findings, AG had a more irregular eating habit than NG (p<0.05). In case of food frequency, AG tended to consume more atopy-related foods than NG (p>0.05). The nutrient intakes of AG were significantly lower than those of NG (p<0.05), but only intake of animal iron in AG was higher than NG (p<0.05). NG consumed more protein than AG (p<0.05). Although milk was a noted hypersensitive allergic food, frequency and the amount of milk intake were not significantly different between two groups. In conclusion, atopic children had eaten more atopy-related foods and less nutrient intakes. Therefore, it is necessary to educate on good nutrition and guide atopic children and their parents.
