Hypertension and obesity are important modifiable risk factors for cardiovascular disease, the leading cause of death in Korea. Therefore, we assessed the association between dietary pattern and obesity in hypertensive patients to formulate health promotion strategies for the older population. Dietary information was collected from hypertensive patients visiting community health education and information center by using 24 hour recall method. The 2005 DRIs for Koreans was used to evaluate the dietary adequacy. When subjects were categorized by body mass index (BMI) as normal, overweight and obese, no significant difference in energy intake was found among groups. Dietary intakes of folate, and vitamin C in obese hypertensive patients were significantly lower than in normal weight patients (p < 0.05). When we compare the nutritional status by waist circumferences, dietary intakes of zinc, vitamin A, thiamin, vitamin C and folate were significantly lower in the obese group. Vegetable intake was significantly lower in the obese group according to BMI as well as waist circumference. Energy intake from carbohydrate was significantly higher in obese hypertensive patients (p < 0.05). Obese hypertensive patients had a higher risk of nutritional inadequacy compared to normal weight patients. Our results indicated the need for developing interventions that encourage greater consumption of vegetables while cutting down salt intake with wise selection of staple foods, for obese hypertensive patients.

The purpose of this study was to explore dietary patterns and compare dietary patterns using cluster and factor analysis in Korean adults. This study analyzed data of 4,182 adult populations who aged 30 and more and had all of socio-demographic, anthropometric, and dietary data from 2005 Korean Health and Nutrition Examination Survey. Socio-demographic data was assessed by questionnaire and dietary data from 24-hour recall method was used. For cluster analysis, the percent of energy intake from each food group was used and 4 patterns were identified: "traditional", "bread, fruit & vegetable, milk", "noodle & egg", and "meat, fish, alcohol". The "traditional" pattern group was more likely to be old, less educated, living in a rural area and had higher percentage of energy intake from carbohydrates than other pattern groups. "Meat, fish, alcohol" group was more likely to be male and higher percentage of energy intake from fat. For factor analysis, mean amount of each food group was used and also 4 patterns were identified; "traditional", "modified", "bread, fruit, milk", and "noodle, egg, mushroom". People who showed higher factor score of "traditional" pattern were more likely to be elderly, less educated, and living in a rural area and higher proportion of energy intake from carbohydrates. In conclusion, three dietary patterns defined by cluster and factor analysis separately were similar and all dietary patterns were affected by socio-demographic factors and nutrient profile.

The purpose of this study was to compare nutrient intakes and blood lipids according to the obesity index of middle aged men. Subjects were assigned to one of the following groups based on percentage of body fat (%Fat),; normal weight (10-20% fat), overweight (20-25% fat) and obesity (over 25% fat). Nutrient intakes were evaluated based on questionnaires and 24 hour recall method and blood lipids were analyzed by blood analyzer. The results were as follows: 1) Nutrient intakes were that carbohydrate intake rate in obesity group was lower than normal group and lipids intake rate in obesity group was higher than normal group. The intake of riboflavin and folic acid were differ normal and obesity group (p < 0.05), and normal group ingested under recommended intake. 2) Total-cholesterol, LDL-cholesterol and blood pressure in obesity group were higher than normal group but the differences were not significant. The attack rate of coronary heart disease and blood glucose in obesity group is higher than normal group (p < 0.05). 3) The correlation of anthropometric measurements, blood lipid, blood glucose and blood pressure had significant results. Soft lean mass was associated BMI (p < 0.01), TC (p < 0.05), HDL (p < 0.05), LDL (p < 0.05) and SBP (p < 0.05). TG was associated TC (p < 0.05), HDL (p < 0.01), VLDL (p < 0.001) and Risk (p < 0.01). TC was associated LDL (p < 0.01) and Risk (p < 0.01). Blood glucose was associated TC (p < 0.05), LDL (p < 0.05), SBP (p < 0.05) and DBP (p < 0.05). These results suggest that reduction of body weight for the attack risk of obesity group in coronary heart disease.

BACKGROUND/OBJECTIVES: Osteoporosis is characterized by low bone mass and results in vulnerability to fracture. Calcium and vitamin D are known to play an important role in bone health. Recently, potassium has been identified as another important factor in skeletal health. We examined the link between potassium intake and bone health among the Korean older adult population. SUBJECTS/METHODS: This retrospective, cross-sectional study included 8,732 men and postmenopausal women over 50 years old who completed the Korean National Health and Nutrition Survey (KNHANES) between 2008 and 2011. Potassium consumption was evaluated using a 24-hour recall method. Bone mineral density (BMD) was measured at three sites (total hip, femur neck, and lumbar spine) by dual-energy X-ray absorptiometry (DEXA). Multinomial logistic regression was used to examine the link between potassium intake and prevalence of osteoporosis and osteopenia, after controlling for potential confounding variables. RESULTS: The BMD of the total femur and Ward's triangle were significantly different according to the potassium intake among men (P = 0.031 and P = 0.010, respectively). Women in the top tertile for potassium intake showed higher BMD than those in the bottom tertile at all measurement sites (all P < 0.05). Daily potassium intake was significantly related to a decreased risk of osteoporosis at the lumbar spine in postmenopausal women (odds ratios: 0.68, 95% confidence interval: 0.48-0.96, P trend = 0.031). However, the dietary potassium level was not related to the risk of osteoporosis in men. CONCLUSION: Current findings indicate that higher dietary potassium levels have a favorable effect on bone health and preventing osteoporosis in older Korean women.

This study was conducted to assess the nutrient intake patterns among urban and rural adolescents and to investigate the effects due to parent's socioeconomic status and other factors, such as mother's job, family type and regular exercise on that pattern. 2,455 middle and high school students living in Seoul and Yangpong, Kyounffi-Do participated in a self-administered questionnaire that was used to collect data. The one-day dietary intake was surveyed through a 24-hour recall method. The factors significantly different between urban and rural adolescents according to monthly income, parent's education level, mother's job, family type and exercise. Income, the parents' education level and regular exercise were associated with the patterns of nutrient intakes as a percent of the RDA. So, when adjusted for parental income, the father's and mother's education level and regular exercise, there were no signifcant differences within the patterns of nutritional intake between urban and rural adolescents. The results provided the information regarding the determinants of nutrient status among adolescents and were expected to be helpful for planning school health promotion programs.

The aim of this study was to assess the nutrient intakes from infant formula and supplemental foods of 246 healthy infants fed infant formula, aged from 5 to 18 months. Subjects were devided into two groups depending on supplemental food type for weaning, Domestic supplemental foods (mainly home-made, n = 129) and Delivery supplemental foods (mainly commercially-delivered, n = 117). Four subgroups were assigned to 5-6 months, 7-8 months, 9-11 months, and 12-18 months by ages, respectively. Dietary assessment was carried out using 24-hour-recall method. Formula intakes in the delivery group tended to decrease accordingly with the ages. However, in the domestic group, formula intakes up to 8 months were similar and decreased after 9 month. Energy, protein, calcium and iron intakes from infant formula and supplemental foods were assessed. Energy intake at 12-18 months were lower than the RDA in both groups. Daily intake of protein and calcium at all ages were much higher than the RDA in both groups. Therefore, protein and calcium overnutrition were elucidated. Especially, protein intake at 5-6 months, calcium intake at all ages from infant formula was higher than the RDA in both groups. Iron intake at 5-6 months from infant formula were higher than the RDA. Consequently, as for infant formula, it was suggested that not only formula intakes but also nutrient content in formula should be reconsidered. On the other hand, nutrient intakes from supplemental foods in the domestic group tended to be higher than that of the delivery group. Especially at 9-11 months, significant differences between the two groups were observed. This may be due to high dependency on commercial powdered baby food in the domestic group. This study revealed that daily nutrient intakes of formula-fed infants are desirable but nutrient intakes from infant formula are too high. Conclusively, this study suggests that as the age of infants increases, formula intakes should be controlled and various supplemental foods besides commercially powdered baby food should be appropriately provided.

The purpose of this study were to determine the folate status of pregnant women living in kwangju, Korea and to assess the relationships between folate status and pregnancy outcome. Eighty-one women took part in the study: 26 in their first trimester of pregnancy, 23 in the second, and 32 in the final trimester. The folate intake data both from their diets and supplementasage was obtained using a 24-hour recall method and by measuring the use of supplements. Folate levels of serum and erythrocytes were determined by a microbiological assay using Lactovacillus casei(ATTC 7469) as the test organism. A series of determinations for pregnancy outcome was conducted, including birth weight, length, Apgar score at 5 min after birth, and gestational period. The dietary folate intake in each trimester was 118$\pm$85, 148$\pm$117, and 137$\pm$69ug/d, respectively. All levels were far below the Korean recommended diet allowances(RDA)for folate. Eighty-four percent of the subjects consumed supplemental folate after the 20th week of pregnancy until delivery. the supplemental folate intakes in the second and third trimester were 651$\pm$142 and 688$\pm$150ug/d, respectively. Therefore, the women who took folate supplements consumed more folate than the RDA. Serum folate levels for each trimester were 9.0$\pm$3.8, 11.4$\pm$6.0, and 16.3$\pm$11.0ng/ml respectively, greadually increasing as the pregnancy progressed; the serum folate level in the third trimester was significantly higher(p<0.05) than that in first trimester. The erythrocyte folate concentrations in each trimester were recorded as 369.8$\pm$108.8, 396.2$\pm$107.5, and 420$\pm$7 162.6ng/ml respectively. There was no significant differences among the erythrocyte folate concentrations unlike the serum folate levels. There was no significant difference among the erythrocyte folate concentrations unlike the serum folate levels. There was no signifcant correlation between trimester to be important in maintaining adequate folate status, however these results imply that the serum and erythrocyte folate levels were adequate to support the growth of the fetus.

Metabolic syndrome (MS) was defined as condition in which the subjects have two or more abnormalities among obesity, hyperlipidemia, hypertension and hyperglycemia. To develop a nutritional education program for MS, this study was performed to compare the dietary habits and nutrients intake of complex symptoms of MS with obesity or hyper-glycemia. The participants in this study were 84 normal adults,62 MS with obesity, 33 MS with hyperglycemia and 54 MS with obesity and hyperglycemia (OB + HG). A dietary survey was conducted using 24-hour recall method. Total cholesterol level of MS with obesity group was significantly higher than other groups. WHR and systolic blood pressure showed no significant difference among MS with obesity, hyperglycemia and OB+HG groups. Dietary intakes of energy, Fe, Vit A, Vit $B_2$ and Ca were less than $75\%$ of 7th Korean RDA in the all groups. Especially, dietary intakes of Vit $B_2$, Vit A and Ca were less than $50\%$ of RDA in MS with hyperglycemia and OB+HG groups. The other nutrient intakes of each group were also below the RDA level except for P, Vit C. It appeared that most of the nutrient intakes in MS with hyperglycemia and OB + HG groups were significantly lower than normal group. In MS with obesity group, each consumption of sweet, organ meat and soup was higher than other groups. Each consumption of garlic and onion in MS with obesity, hyperglycemia and OB + HG groups was lower than normal group. Also, each consumption of soup in MS with hyperglycemia and OB + HG groups was higher than normal group. Indices of nutritional quality (INQ) for Ca, Vit A and Vit $B_2$ were below 1 in all the groups. Food composition group score of MS with hyperglycemia group was significantly lower than normal and MS with obesity groups. Our results indicated that nutritional education program for MS with obesity or hyperglycemia should include specific strategies to modify unsound dietary habits and inappropriate food intake for health.

This study was conducted to examine dietary factors affecting bone status in the rural aged men. Quantitative ultrasound measurements (QUS) of bone, that may reflect certain architectural aspects of bone, have been shown to be associated with bone mineral density and fracture. Information of diet and anthropometry was collected in 164 aged men. Dietary intake data were obtained by 24-hour recall method. Measurements of the speed of sound (SOS, m/s), at distal radius, mid-tibia, phalanx, were performed using Omnisense 7000S analyzer (Sunlight Ltd., Tel Aviv, Israel). T-scores for bone SOS measurements at distal radius, mid-tibia and phalanx were 0.60, 0.03 and -0.42 respectively. The prevalence of osteopenia by use of the WHO criteria was 17.7% at the mid-tibia and 25.3% of the subjects at the distal radius. Age were negative association with bone SOS at three sites. Osteopenia group of radius were significantly lower in total foods and vegetable intakes than normal group. After adjusted for age, vegetable intakes were significantly and positively related to bone SOS at the radius. The bone SOS of the tibia were significantly and positively related to vegetable protein, iron, folate and vegetable intakes, but negatively related to fat intakes. Multiple regression analysis showed that bone SOS of tibia was positively associated with folate intakes. Vegetable intakes were positively associated with the bone SOS at three sites. These results indicate that the consumption of vegetables, sources of folate, may have a effect on bone status of men.

Recent researches suggest that carotenoids are important not only as provitamin A but also for prevention of chronic diseases. This study was conduction to determine levels and factors affecting serum levels of lutein + zeaxanthin, $\beta$-cryptoxanthin, and $\beta$-carotene in 93 adults living in rural area of Korea. Fasting blood samples were collected and serum carotenoid levels were measured by HPLC. Dietary intake was estimated by 24 hour recall method and frequency questionnare of major food groups. Mean serum concentration of lutein + zeaxanthin was 616.32 nmol/L, $\beta$-cryptoxanthin was 856.95nmol/L, and $\beta$-carotene was 242.90nmol/L. Serum $\beta$-carotene levels in study subjects were very low. Both $\beta$-cryptxanthin and $\beta$-carotene were negatively correlated with serum triglyceride and positively correlated with total-choesterol and LDL-cholesterol. Serum levels of female subjects were significantly higher than males in all carotenoids. For age groups, subjects in their 30's were shown to have the highest concentration of all carotenoids. Lutein + zeaxanthin were lowest in subjects in theri 40's while $\beta$-crytoxanthin and $\beta$-carotene levels were lowest in subjects in their 60's. The $\beta$-carotene levels in non-smokers were significantly higher than in drinkers. Lutein+zeaxanthin levels were significantly higher among subjects consuming more green and yellow vegetables by frequency questionnarie. In conclusion, serum carotenoids were affected by sex, age, serum lipids, smoking, and alcohol intake. Intake of vegetables and fruits could affect by sex, serum lipids, smoking, and alchol intake. Intake of vegetables and fruits could affect serum lutein+zeaxanthin level. This data indicated that compared to other studies, Korean adults in rural areas have high lutein+zeaxanthin concentratins and low $\beta$-carotene concentrations in serum. High lutein+zeaxanthin levels may be related to high consumption of vegetables in these subjects.
