The purpose of this study was to identify dietary patterns among children and adolescents in Korea and to examine their associations with obesity and some blood profiles. One day food consumption data measured by 24-hour recalls on 2704 subjects aged 1 to 19 were used from 2001 Korea National Health and Nutrition Survey. The data of blood profiles available in the ages of 10 or older was also used. After categorizing each food consumed into 29 food or food groups, five dietary patterns were derived through a factor analysis and subjects were classified into three major dietary patterns via a cluster analysis using the factor scores. Three dietary patterns were identified as 'traditional diet' (25.6%), 'westernized-fast food' (6.2%), and 'mixed diet' (68.2%). The 'traditional diet' pattern had a higher percentage in boys. Both the 'traditional diet' and the 'westernized-fast food' had higher proportions of adolescents (12-19 y) than younger children, while the 'mixed diet' had a higher percentage of preschool children (1-5 y). Obesity rate analyzed within each age group showed no differences among 3 dietary pattern clusters. Blood pressure and all plasma profiles were not different among dietary patterns when adjusted with age and gender. Conclusively, children and adolescents in Korea had three distinct dietary patterns, which were associated with gender and age. These patterns could be useful to plan nutrition interventions for teenager health promotion.

The purpose of this research is to investigate factors that influence weight control behavior(WCB) of young women in Korea. Data were obtained from the 2013 Community Health Survey which was conducted nationally. The study subject comprised 13,351 women ranging in age from 19 to 29. Data were analyzed using ${\chi}2$-test and multivariate logistic regression analysis. WCB showed differences in age, marital status, education, family type, BMI, perceived health status, subjective obesity, high risk drinking, weekday sedentary leisure-time activity, breakfast skipping, sleeping time, perceived stress, depression and suicidal ideation. And the significant predictors of WCB were age, marital status, education, family type, BMI, perceived health status, subjective obesity, high risk drinking, weekday sedentary leisure-time activity, perceived stress and depression. In conclusion, it is suggested that approach to WCB should be considered in correlation between WCB and other health behaviors.

Purpose: Poor physiological reserve for withstanding major cancer surgery in older adults is an important concern in the selection of patients for oncologic gastrectomy. The present study aimed to analyze mortality patterns among patients who underwent gastrectomy for cancer according to age groups. The primary outcomes of this study were early- and middleterm results: 30-day and 3-, 6-, 12-, and 36-month mortality rates. Materials and Methods: A retrospective review of 288 patients who underwent surgical resection for gastric cancer in two centers was carried out. Patients were stratified into four groups according to age: 29-50 years (group I, n=27), 51-65 years (group II, n=117), 66-75 years (group III, n=81), and 76-92 years (group IV, n=58). Statistical calculations focused on the differences in the survival rates between groups I and II as well as between groups II and IV. Results: The middle-aged patients (group II) had significantly better 3-year survival than either the youngest (group I) or the oldest patients (group IV). The 6-month mortality rates were 16.9% in group III and 29.3% in group IV. Two-thirds of the patients from groups III and IV who died between 2 and 6 months after surgery had an uneventful postoperative course. Conclusions: Age is an important prognostic factor of middle-term survival after gastrectomy for cancer. Geriatric assessment and better patient selection for major surgery for cancer are required to improve the outcome of gastrectomy for cancer in patients aged over 75 years.

Purpose: The nutritional status of folate in Korean adults was evaluated using the newly established folate database (DB) and data from the 7th Korea National Health and Nutrition Examination Survey. Methods: This study analyzed the folate intake of 15,054 people (6,278 men and 8,776 women) and the relationship with serum folate concentration of 5,260 people (2,272 men and 2,988 women). Results: The average daily folate intake among Korean adults was lowest in the 19 to 29-year age group and highest in those in their 50s. Folate intake was higher in groups with higher education and household income, non-smokers, participants in aerobic physical activity, and dietary supplement users regardless of sex. Among men, office workers consumed more folate than physical workers. Vegetables and grains were the first and second most contributing food groups to folate intake. The serum folate levels were higher in women than men and lowest in the 19-29 year age group for both sexes. After adjusting for energy intake, age, income, smoking, physical activity, and dietary supplement intake, serum folate concentration increased significantly as intake increased (p < 0.001). The explanatory power (R²) of folate intake on the blood folate concentration was 0.183 and 0.141 in men and women, respectively. Conclusion: The proportion of participants consuming less than the estimated average requirement was 48.1% and 65.3% in men and women, respectively. In particular, the folate intake and serum levels of young men aged 19-29 years were the lowest. Therefore, it is necessary to improve their folate nutritional status through a balanced diet. In addition, the newly established folate DB may be useful for evaluating the folate nutritional status of Koreans.

This study was carried out to get basic information that can be used in quality control for processing ginseng products and also in separation of pure ginsenosides for experimental purpose. The composition of various parts of 6 year-old ginseng was 4.1% of rhizome (node), 47.7% of main root, 34.1% of lateral root and 14.1% of fine Toot on dried weight basis. The weight ratios of epidermis-cortex and xylem were about 1 : 1 in main root and about 2 : 1 in lateral root. The distribution of total saponin content shows 29.2% in main root, 34.6% in lateral root, 29.1% in fine root and 7% in rhizome, but the order of the content per unit weight was fine root > rhizome > lateral root > main root. Total saponin content according to age of root was increased gradually within 3% for 6 years, as compared with two year old root. In view of the increase of root weight owing to the net amount of saponin in root increased continuously. The increase rates of total saponins per year were 3.1,12.3,19.8,43.8 and 21.1% in 2, 3, 4, 5 and 6 years-old ginseng root, respectively.

This study investigates nationwide anthropometric survey that were conducted during the past 40 years- in Korea. It is focused on the national anthropometric survey of 1986 as the present state. The result of '86 survey were compared with these of the past survey and the foreign surveys. The stature and body weight increased compared with those of the past, but the sitting height and bust circumference decreased or showed almost similar growth tendancy up to the end of growth stage. Koreans are generally larger than Japaneses up to age 14, but smaller above age 14. Compared with Americans, Koreans are not smaller up to age 12, but above that, differences start to appear and big differences exist between the two races in the growth cease stage.
