This study was carried out to examine nutrients intake and food preference in 100 elderly people aged over 85 years residing in Namhae-gun Kyungnam. Mean daily energy intake and Korean recommended dietary allowances (RDA) percent were 1547.6$\pm$452.7 kcal and 91.5%, respectively. Mean daily intakes of protein (63.1$\pm$28.2 g), iron (16.7$\pm$11.2 mg), vitamin Bi (1.0410.4 mg) and vitamin C (97.0$\pm$45.3 mg) were higher than RDA. The intakes of calcium (418.1$\pm$189.7 mg) and vitamin B2 (0.94$\pm$0.5 mg) were shown to be 58.4% and 78.4% of the RDA. Females had higher intakes of energy and most other nutrients than males. Major food source of energy and protein intakes was rice and cereals, and that of lipid intake was meat, fish, egg and beans. Cooked rice, all kind of vegetables, fish, yogurt and sugars were preferred to the subjects. The most preferred taste was sweet.

Objectives : The aim of this study was to evaluate the relation between the state of dental health(number of natural teeth) and nutritional status of Korean elderly using Korean Dietary Reference Intakes, which was an objective standard for nutritional intake based on database of Korea National Health and Nutrition Examination Survey, large scale of sample obtained by the government. Methods : Complex sampling procedure was used to analyze the fourth data(2007-2009) of Korea National Health and Nutrition Examination Survey. When preparing planning file, the estimator of variance as a stratification variance (variance name : kstrata), population of survey unit as a cluster variance(variance name : PSU), and previous exam and nutritional related weighted as a weighted were analyzed by considering reproduced survey and nutritional related total weighted. Complex samples chi-square test was used to estimate the relation between number of natural teeth and inadequate intake and relation factors included in the model were analyzed by complex samples logistic regression analysis. Results : The group of edentulous had a higher risk to intake less nutrient, except calcium, riboflavin and vitamin C than recommended level comparing to reference group which had natural teeth more than 20(phosphate : OR=1.763; 95% CI=1.273-2.443, thiamine : OR=1.748; 95% CI=1.276-2.395, protein : OR=1.610; 95% CI=1.213-2.138). Conclusions : The number of teeth in Korean elderly over 65 years old had a relation with nutritional status in this investigation. Especially, intake level of nutrients was different between the edentulous group and the reference group. Therefore, dental health care is needed from young and middle age to keep health dental condition for through whole life as well as old age. Although the dental condition of the aged is not good, it is evitable to educate them about the relation between dental health and nutritional ingestion to take balanced nutrition, we think.

Objectives: To evaluate the critical environmental factors on healthy-aging of Korean people, we investigated the significant factors influencing health status of septuagenarians living in rural area of Jeonla province, known to be one of the representative longevity regions in Korea. Methods: We divided subjects into healthy group (36M/25F) or poor-health group (26M/73F) based on self-reported health status, body mass index, a number of prescription, and blood test data. General characteristics, physical measurements, lifestyle, dietary behavior and nutrient intake, physical health and mental health data were statistically compared between the two groups. Results: Average age was not different between healthy group and poor-health group in men and women, respectively. In men, significantly favorable factors to health were observed to be higher education, regular exercise, higher grip strength and walking function, body mass index (${\geq}18.5kg/m^2$), moderate frequency of drinking and eating-out, non-smoking, normal red blood cell (RBC) count, higher serum dehydroepiandrosterone-sulfate (DHEAS) level, good digestive function and appetite, normal hearing function, regular meals, adequate vegetable and fruit intake, diverse food intake, adequate energy and nutrients (protein, vitamin $B_1$, $B_6$, C and E, folate, niacin, P, Zn and K) intake, higher mini-nutrient status assessment (MNA) score and low level of depression. On the other hand, in women, those were literacy, living arrangement, moderate frequency of drinking, healthy teeth, higher grip strength and walking function, bone mineral density, normal RBC and white blood cell (WBC) count, higher DHEAS concentration, higher MNA score, normal cognition and memory function, having snack and adequate fruit intake. Conclusions: These results could be useful to plan effective strategies to increase health-life expectancy of Korean old people living in rural areas.

The aim of this study was to measure and compare nutrient intake, anthropometric measurements and serum indices by percent body fat as one of the index of obesity degree in female college students. Additionally we attempted to investigate percentile distribution of fat free mass index (FFMI) and fat mass index (FMI) for developing reference values for these two parameters. The subjects were 91 female college students who were classified to 4 groups according to the percentile of percent body fat (Group1: 25 th < percentile of percent body fat, Group 2 : 25 th ${\le}$ percentile of percent body fat < 50 th, Group 3 : 50 th ${\le}$ percentile of percent body fat < 75 th, Group 4 : percentile of percent body fat ${\ge}$ 75 th). The mean percent body fat and body mass index were 28.2%, $20.5 kg/m^2$ respectively. The mean energy intake was 1707 kcal(81% of KDRIs) and vitamin C, folate, Ca and Zn intake were 73.9%, 54.7%, 79.6%, 97.5% of KDRIs respectively. Most nutrient intake (energy, carbohydrate, cholesterol, fatty acid, Ca, Fe) of G4 was lower than that of G1, G2 and G3. Serum HDL-cholesterol concentration was significantly lower in G4 than G1, G2, G3 and it tended to increase as percent body fat decreased. LDL/HDL, A1 of G4 were significantly the highest among the 4 groups and increased as percent body fat increased. The mean fat free mass index and fat mass index were $14.5 kg/m^2$, $6.0 kg/m^2$ respectively. The criteria of sarcopenic obesity which has been defined as under 25 th percentile of FFMI and below 75 th percentile of FMI were shown $12.8 kg/m^2$, $8.2 kg/m^2$ respectively in this study. In conclusion, we should continue to more systematically research on the studies of new obesity measurement which includes FFMI and FMI as one of the variables. And the public education for weight control that emphasizes both the understanding of body composition and the importance of nutrition balance is also required.

Purpose: The aim of this study was to examine the characteristics of nutrition-related knowledge, dietary habits, and nutrient intakes of alcoholic patients and how nutrition education affects these nutritional behaviors. Methods: Subjects included 37 adult male alcoholic patients who were hospitalized. The nutrition education program consisted of five lessons over a five-week period. An each 80-minute nutrition education program per week was implemented for the alcoholic patients over a five-week period. Both before and after the implementation of nutrition education, their nutrition-related knowledge and dietary habits were assessed and nutrient intakes were investigated. Results: The subjects showed drinking habits of considerably high frequency, a large quantity of alcohol consumption, and preference for soju (a liquor) over beer. They had proper weight, height, and BMI, and came from relatively poor socioeconomic backgrounds with a low-level of self-rated health status and a comparatively high rate of suffering from disease. Mean score of their nutrition-related knowledge and dietary habits was quite low. They consumed less energy, dietary fiber, vitamin C, thiamin, riboflavin, folic acid, Ca, and K, but more Na compared to each Dietary Reference Intake (DRI). After implementing the nutrition education, mean score of nutrition-related knowledge and dietary habits showed significant improvement. In addition, the meeting rate of each DRI of several nutrients was increased significantly, including energy, carbohydrate, dietary fiber, vitamins A, C, and $B_6$, thiamin, riboflavin, niacin, pyridoxine, folic acid, Ca, P, K, Fe, and Zn, while that of Na decreased. Conclusion: The findings of this study indicate that alcoholic patients had various nutritional problems, such as lack of nutrition-related knowledge, bad dietary habits, and insufficient nutrient intakes, however, these problems can be positively modified by implementation of a relatively short-term nutrition education program.

This study aims at investigating the health and nutritional status of the adults according to frequency of eating out. One day food intake data were collected by 24 hr recall dietary survey and body size, blood pressure and some blood lipids and other constituents were measured on 137 Daejeon metropolitan citizens 20 yrs old and above who visited Chungnam National University Hospital for physical examination during the period of December 6, to December 15, 2008. The frequency of eating out were categorized into four levels: less than once a week, once a week, 2-3 times a week, 4 times a week and above. Body mass Index, waist circumference, blood pressure, blood lipid, blood glucose, GPT and GOT did not showed any significant difference according to the frequency of eating out of the subjects. Though, systolic blood pressures and serum levels of total cholesterol and LDL-cholesterol showed a little tendency to be high in the subjects eating out 2-3 times a week. In the contrary, serum triglyceride level tended to be low in the same group. The subjects eating out 4 times a week and over took more total protein, animal protein, animal fat, phosphorus and vitamin $B_2$ than any other group. Also protein energy ratio was the highest in the group eating out 4 times a week and above and they took more animal food group, other food group, beverages teas and alcohols than other groups eating out. These results showed that higher frequency of eating out leads to higher intake of protein, fat, phosphorus, animal food groups and other food groups (oils, beverages, seasonings) and to lower intake of vitamin C and plant food groups. It, thus, suggested that the strategy for restaurant business is required to provide the menu substituted animal food by more plant food.

Purpose: This study was performed to identify the health and nutritional status of Korean adults according to food security by age group. Methods: The subjects were 20~79 year old adults (n = 16,595) who participated in the fifth Korea National Health and Nutrition Examination Survey (2010~2012). Subjects were divided into three groups based on food security such as secure, mildly insecure, and moderately/severely insecure groups. Dietary intake was estimated by 24-hour dietary recall. As for mental health status, the data on mental stress, sleep hours, depression symptoms, and suicide ideation were used. Results: Korean adults who were exposed to high food insecurity typically had low income levels, lived alone, and were recipients of basic welfare. In the 20~39y group, people with higher food insecurity had lower concentrations of hemoglobin and higher iron-binding capacity. In the 40~59y group, people with higher food insecurity had lower HDL-cholesterol. In the 60~79y group, people with higher food insecurity had higher total cholesterol levels, more stress, more experiences of depression symptoms, and were more suicidal. Mean intakes of energy, protein, calcium, phosphorus, potassium, vitamin A, carotene, vitamin $B_1$, vitamin $B_2$, niacin, and vitamin C were lower in the food insecure groups. Amounts of vegetables, fruits, and seasoning intakes tended to be lower in people with higher food insecurity. The effects of food security on nutrition intake were greater in the 40~59y and 60~79y groups than the 20-39y group. Conclusion: Food insecurity was related to certain health indicators such as anemia and cholesterol levels and affected mental health. The effects of food insecurity on health and nutritional status were different by age group.

Purpose: The purpose of the present study is to identify the relationship between practicing healthy diet and metabolic syndrome indicators in Koreans. Methods: This research is a cross-sectional study based on the 2013~2014 Korea National Health and Nutritional Examination Survey. This study investigated 6,748 adults aged 19 to 64 yr (19~49 yr: n = 4,230, 50~64 yr: n = 2,518) to examine practice of healthy diet and metabolic syndrome indicators. In this study, according to practicing healthy diet, we classified subjects into the "Practicing healthy diet (PHD)" group (19~49 yr: n = 1,782, 50~64 yr: n = 937) and "Non-practicing healthy diet (NPHD)" group (19~49 yr: n = 2,448, 50~64 yr: n = 1,581). PHD score was determined by adding the number of practicing factors: adequate fat intake, sodium intake ${\leq}2,000mg/day$, fruit & vegetable intake ${\geq}500g/day$, and using nutrition label information in food selection. Results: Female adults had a larger proportion of subjects who practiced a healthy diet compared to male adults (p < 0.001), and the percentages of 19~49 yr and 50~64 yr were 40.46% and 37.07%, respectively. The PHD group consumed significantly more calcium, vitamin $B_1$, $B_2$, and vitamin C density compared to the NPHD group. In 50~64 yr females, the subjects practicing healthy diet (PHD score ${\geq}2$) was inversely associated with risk of abdominal obesity (OR: 0.71, 95% CI: 0.54~0.93, p value = 0.0131) and metabolic syndrome (OR: 0.70, 95% CI: 0.52~0.94, p value = 0.0166) after adjustments for multiple confounding factors, compared with the lower PHD score (PHD score ${\leq}1$). Conclusion: Good dietary practice such as adequate fat intake, sodium intake ${\leq}2,000mg/day$, sufficient fruit & vegetable intake, and using nutrition label information in food selection could be useful in decreasing metabolic syndrome risk of Korean adults.

Purpose: The prevalence of metabolic syndrome has increased in both the adult population and in adolescents. However, few studies have been conducted for adolescents. The aim of this study was to examine the association of metabolic syndrome and its risk factors with high carbohydrate diet and high fat diet using data from the Korea National Health and Nutrition Examination Survey (1998-2009). Methods: Using the Acceptable Macronutrient Distribution Range for Korean Dietary Reference Intakes, subjects whose energy intake from carbohydrate was greater than 70% and from fat was less than 15% were classified as the 'High-carbohydrate & low-fat diet (HCLF)' group and subjects whose energy intake from carbohydrate was less than 60% and from fat was 25% or more were classified as the 'Low-carbohydrate & high-fat Diet (LCHF)' group. Among 5,931 eligible subjects, HCLF included 853 subjects and LCHF included 1,084 subjects. Results: The mean age in both groups was 14 years and significant difference in age, BMI, sex, physical activity, and household income was observed between the HCLF and LCHF groups. Regarding the energy intake compared to Estimated Energy Requirement, the HCLF group met 79.0% and the LCHF group met 100.3%. Regarding nutrient intake per 1,000 kcal, carbohydrate, iron, potassium, and vitamin C intake in the HCLF group were significantly higher, but protein, fat, calcium, phosphorus, vitamin A, thiamin, riboflavin, and niacin intakes were significantly lower in the HCLF group compared to the LCHF group. After adjusting for age, sex, BMI, study year, household income, physical activity, and energy intake, the serum triglycerides level and systolic blood pressure were slightly higher, while the serum HDL-cholesterol level was significantly lower in HCLF than LCHF. The odds ratio of metabolic syndrome did not differ significantly between HCLF and LCHF. Conclusion: Our findings indicate an association of a high carbohydrate diet with increased risks for metabolic syndrome components. Conduct of future studies would be necessary in order to explore the underlying mechanism and to confirm our findings in a prospective study.

Purpose: This study examined the food and nutrient intake of Korean elderly according to the anxiety and depressive condition using the data from the Korea National Health and Nutrition Survey (KNHANES) from 2013 to 2015. Methods: The participants were 3,504 elderly people over 65 years of age (1,523 in men and, 1,981 in women). The dietary information was analyzed using the 24-hour recall data. The anxiety and depressive state was assessed using the self-reported scale EQ-5D in the quality of life dimension. The subjects were divided into the anxiety depression group (AD) and non-anxiety depression group (NAD) according to their anxiety and depressive conditions. Results: In the male elderly, the AD group had a significantly lower education and economic level and higher proportion in living alone than the NAD group. The percentage of eating lunch and dinner alone in the male AD group was higher than that of the NAD group. The female AD group showed less a lower frequency of dinner than the NAD group. The male AD group had a lower consumption of total foods, fish and shellfishes, seaweeds, mushrooms, oils and fats, and seasonings than the NAD group. With regard to the nutrient intake, the male elderly NAD group had more sufficient nutrient intakes than the AD group. In particular, the daily intakes of dietary fiber, riboflavin, niacin, potassium and iron were significantly lower in the AD group. To compare with the nutrient density of the two groups, the vitamin C and niacin intakes were lower in the AD group than in the NAD group. Overall, the nutritional status of the male AD group was significantly lower than that of the NAD group. Meanwhile, the female elderly had showed a smaller difference in nutrient intake according to their anxiety and depressive condition. Conclusion: These results of this study show that more nutritional education and emotional support are needed to improve the nutritional status and health of the male elderly with anxiety or depression.
