- Several nutrients are known to affect bone mineral density (BMD). However, these nutrients are combined with food intake and dietary patterns and little is known about the association of dietary patterns and BMD. The objective of this study was to investigate the association of dietary patterns with BMD in Korea Genome Epidemiology Study subjects. Among 2,884 women (40-69 yr) recruited at baseline study (2001), 861 subjects with BMD measurements at baseline and a 4-year follow up study (2005) completed the semi-quantitative food frequency questionnaire. BMD was measured by the Quantitative Ultrasound method. One hundred three food items were combined into 17 food groups and 4 dietary patterns were identified by factor analysis. Cluster analysis using factor score classified each subject into one of three dietary pattern groups named 'Rice and kimchi eating' (n = 617), 'Contented eating' (n = 124), and 'Healthy and light eating' (n = 120). The 'Healthy and light eating' group, characterized by higher intake of fruit, vegetables, fish, milk and dairy products, and younger age, more exercise, higher education, and higher income than other groups. The tibia BMD of the 'Healthy and light eating' group was higher than the other groups after adjusting for the age. After the adjustment for the age BMI and exercise, the 'Healthy and light eating' group showed significantly lower odds of tibia osteopenia/osteoporosis risk compared to the 'Rice and kimchi eating' group both at the baseline [OR(95% CI) : 0.50(0.30-0.84)] and follow-up [OR(95% CI) : 0.59(0.36-0.97)] examinations. The dietary pattern with low calorie and high intakes of fruit, vegetables, fish, milk and dairy products may have beneficial effects on BMD in middle-aged women.

- The purpose of this study was to plan a 5-day menu using antioxidant-rich foods (vitamin A, vitamin C, vitamin E, phytochemicals) for a congregate meal program for the elderly and to evaluate the satisfaction of menus. The elderly participated in the congregate meal program at Guro Elderly Welfare Facility during October, 2003 (120 persons/day). The elderly liked yungyangbab, cooked rice with sweet potato and pumpkin, soybean paste soup with chinese cabbage, pan-fried cuttlefish patty with chopped soybean sprout, pan-fried beef patty with tofu and ginseng, fresh vegetable salad and most of desserts. The leftovers of menus were negatively correlated with satisfaction of menus. The 5-day menu contained over 1/3 of KDRIs (Dietary Reference Intakes for Koreans) except fiber, calcium, vitamin K and vitamin E. In conclusion, menus using antioxidant-rich foods for a congregate meal program for the elderly will improve nutrient intakes and satisfaction of the meal program. It may help to prevent chronic diseases and improve healthy lives of the Korean elderly.

- This study was performed to test food preferences of the Korean elderly for Korean elderly menu development. The elderly subjects preferred steamed rice cooked with 1.2 times water than that with 1.5 times water (p < 0.001), whole rice grain gruel than the gruel with ground grain (p < 0.05). Green tea powder gruels developed as a snack, there were no significant differences in the preference of the elderly between gruel with different contents of green tea powder (2, 3, 4%). The preferences of the salt concentration of the soup were tested by using soybean sprout soup and soybean paste soup. The elderly preferred 0.7 - 0.8% salted bean sprout soup and 7% soybean paste soup. The elderly preferred Kimchi cut in widths of 1 - 2 cm than that in 0.5 cm. The elderly preferred sweeter grape jam (67% vs. 50% or 37% sugar content) and were not concerned about chewing seeds. This result could be useful to develop menus for the elderly.

- This study was conducted to investigate osteopenia and osteoporosis prevalence of radius and tibia using Quantitative Ultrasound (QUS) and to identify affecting factors of osteoporosis. A total of 4,340 women aged 40 - 69 years, living in Ansung (rural) and Ansan (mid-sized) area, and free of illnesses affecting bone metabolism participated in the community-based cohort study. Among them 4,059 subjects measured radius bone density and 4,089 measured tibia. The T-score threshold, defined as < -1.0 and < or = -2.5, was used to identify subjects with osteopenia and osteoporosis by WHO criteria. The crude prevalence of osteoporosis in radius and tibia was 8.4% and 23.3% respectively; after adjustment for age, it changed 6.3% and 18.8%. In simple logistic regression analysis, the prevalence of osteoporosis increased by aging, non-marital status, low education, low income. Otherwise, high intakes of Ca/P, thiamin, riboflavin, vitamin B6, and vitamin E were decreased osteoporosis prevalence. Compared to the normal BMI (body mass index) group (18.5 < or = BMI < 23), the odds ratio (ORs) of the low BMI group (BMI < 18.5), and high BMI groups (BMI 25 - 30, BMI > or = 30) were significantly increased. The OR of osteoporosis decreased across increasing quartiles of intakes of Ca, P and Ca/P. Therefore, maintaining normal BMI and increasing Ca intake and Ca/P ratio may have a beneficial effect on bone health of Korean women.

- Carotenoid-rich foods focus one's attention on the prevention age-related diseases. This study was conducted to investigate the carotenoid status and look into the factors that affect the bioavailability of carotenoid in 121 elderly nonsmoking Korean women. Carotenoids and lipids in plasma, and nutrient intakes including carotenoid were studied. The mean plasma total-cholesterol, HDL-cholesterol, LDL-cholesterol and triacylglycerol concentrations were 220.0 mg/dl, 49.5 mg/dl, 139.2 mg/dl and 157.4 mg/dl, respectively. Significantly positive correlations were found between the plasma lutein + zeaxanthin, lycopene and beta-carotene concentrations and the intake of fruits (r = 0.17, r = 0.20, r = 0.19). However, significantly negative correlations were found between the plasma lutein+zeaxanthin, and beta-carotene concentrations that adjusted for carotenoid intakes and intakes of vegetables (r = - 0.21, r = - 0.19), and between plasma lutein+zeaxanthin, lycopene and beta-carotene concentrations that adjusted for carotenoid intakes and intakes of fruits (r = - 0.21, r = - 0.18, r = - 0.24). After the adjustment for plasma lipids, there was no correlation between the plasma carotenoid concentrations and the carotenoid-rich foods. However, after adjustment for fiber intake, significantly strong positive correlations were found between the plasma carotenoid concentrations and carotenoid-rich foods.
The plasma levels of carotenoid biomarkers (plasma carotenoid concentrations adjusted for dietary fiber intakes) decreased with age, and the plasma levels of lycopene biomarkers (plasma lycopene concentrations adjusted for dietary fiber intakes) increased with regular exercise. However alcohol drinking had no impact. These results suggested that age, physical activity, and dietary fiber intake affected the bioavailability of carotenoid. Therefore, when the elderly have carotenoid-rich foods, they should consider ways of increasing the bioavailability of carotenoid through cooking methods and physical activity.

- The relationship between dietary practices and juvenile delinquency was studied using a dietary survey. Subjects were selected from juvenile delinquents who were under the supervision of the Seoul Probation Office of the Ministry of Justice. The study group consisted of 52 male and 52 female delinquents. As a control group, 104 exemplary high school students were selected in Seoul. A questionnaire was designed to find out the subjects' general characteristics, dietary habits, lifestyle, eating behavior, food frequency, and nutrient intake using the 24-hour recall method. Compared to the exemplary students, the juvenile delinquents were significantly different in education level, family status, monthly allowance, residence status, breast fed, parents' education level, parents' concern. In dietary habits, fifty-eight percent of the juvenile delinquents ate 2 or fewer meals per day, preferred to eat with friends, and liked hot tasting foods. The juvenile delinquents consumed more ion drinks (OR=9.26 CI: 3.83-22.37), rameon (OR=7.67 CI: 3.21-18.33), cola (OR=6.75 CI: 2.91-15.69), soft drinks (OR=6.12 CI: 2.53-14.81), steamed korean sausage (OR=5.34 CI:2.31-12.32), hamburger (OR=5.15 CI: 1.91-13.87), kimbab (OR=3.63 CI: 1.76-7.46), ddokbokgi (OR=3.17 CI: 1.58-6.38), candy (OR=3.08 CI: 1.41-6.73), white rice (OR=2.59 CI: 1.19-5.64), hotdog (OR=2.52 CI: 1.31-4.86), and less rice mixed with grains (OR=0.02 CI: 0.01-0.05), tangerine (OR=0.06 CI: 0.02-0.20), milk (OR=0.29 CI: 0.14-0.60), roasted fish (OR=0.32 CI: 0.28-0.99, anchovy (OR=0.35 CI: 0.17-0.72), seaweed (OR=0.37 CI: 0.16-0.83), and tofu (OR=0.48 CI: 0.23-0.99) than the exemplary students. With respect to the juvenile delinquents, the nutrient intakes lower than 75% of the Korean RDA were for riboflavin (75.0%) and calcium (47.9%) among the boys, and calcium (46.9%) and iron (60.4%) among the girls. To prevent juvenile delinquency, nutritional education and well-balanced school food service meals should be emphasized so as to improve the management of dietary practices.

- The aim of this study was to assess the nutrient intakes of the elderly subjects in Korea. Dietary assessment was carried out using a semi-quantitative food frequency questionnaire (SQFFQ) developed by our laboratory, which included 98 commonly consumed food items selected from 1998 National Health and Nutritional Survey for Korean population. Subjects (n = 2,660) aged 50yr and over were recruited in Seoul, 6 metropolitan cities, and 8 mid-size cities. Calcium and riboflavin intakes of the elderly subjects aged 65 yr and over (n = 1,974) were much lower compared with Korean RDA. Nutrient intakes of the three age group (50-64 yr, 65-74 yr, 75 yr and over) were decreased as age increased in male and female elderly. Nutrient intakes of male elderly, 75 yr and over, were significantly decreased while in female elderly nutrient intakes were gradually decreased as age increased. Over 30% of the elderly subjects did not meet 75% RDA for calcium, iron, vitamin A, and riboflavin. The proportion of the elderly subjects whose intakes were below 75% RDA was much higher than the elderly whose intakes were above 125% RDA, especially among the elderly aged 75 yr and over. This study revealed that the Korean elderly had inadequate intakes for many nutrients. This will cause a serious nutritional problem for the elderly.

- The purpose of this study was to develop a semi-quantitative food frequency questionnaire (SQ-FFQ) for subjects aged 50yr and over and to evaluate the validity of this SQ-FFQ. Dietary intake was assessed using SQ-FFQ that included 98 commonly consumed flood items selected from the results of the Korean Health and Nutritional Survey, 1998. Subjects (n = 2,660) aged 50yr and over were recruited from 7 metropolitan cities and 8 small cities. Each subject was interviewed using this SQ-FFQ developed in our laboratory and 24hr-recall method. Excluding incomplete data, Data from 1,149 subjects were used in this validity study. The nutrient intakes assessed by this SQ-FFQ were validated by comparing with the results from 1 day 24-hour recalls. Pearson's correlation coefficients between two methods were 0.71, 0.64, 0.53, and 0.43 for energy, carbohydrate, protein, and fat, respectively for all subjects. Spearman's correlation coefficients were higher than those of Pearson's correlation coefficients. Kappa values for energy, carbohydrate, protein, and fat were 0.79, 0.72, 0.70, and 0.64, respectively. The percentage for misclassification of the lowest quartile into the highest quartile or vice versa was 1.25-1.39% for all nutrients. Therefore, this SQ-FFQ seems to be useful in assessing the nutritional status of the middle-aged and elderly subjects in Korea.
