This study was carried out to compare the nutrients intakes, factors to influence on nutrient intake and frequency of food group intake between the two gruops of elderly living in Yangcheon, Seoul(n=105) and in Yongin(n=159). The results obtained by cross-sectional survey using questionnaires were as follows. 1) The average age of the subjects was 71.9 and there was no significant difference in age and gender distribution according to the residential areas. 2) The intakes of energy, protein, Fe, vitamin A, niacin, thiamin, riboflavin, and vitamin C were significantly higher in the urban elderly than those of the rural elderly(p<0.05).3) The average daily intakes of energy, protein, Ca and Fe of the subjects were lower than those of the Korean RDAs in general and the rural elderly showed more severe deficiencies. 4) Individual nutrient intakes and food group intakes were related to the pocket money, number of different foods taken daily, education level, residential area, and the degree of exercise. These results suggested the needs of nutrition intervention for the low-income, rural elderly.

The purpose of this study was to examine the association between fatty acid intake and dyslipidemia in Korean adults, using data from the Korean National Health and Nutrition Examination Survey (KNHANES)I, II, III, and IV. After excluding subjects who had missing data for the dietary intakes, anthropometric measurments and laboratory tests, a total of 15,804 subjects aged 20~64 y (6,838 men and 8,966 women) from KNHANES 1998~2007 were included. All data were analyzed using SPSS Statistics software (version 18.0). Associations between fatty acid intakes and dyslipidemia were analyzed by logistic regression analysis after adjusting for age, BMI, energy intake, marital status, job, education level, alcohol intake, and smoking status. Fatty acid intakes were significantly higher in men than in women. The risk of hypertriglyceridemia was significantly and negatively associated with intakes of TFA, SFA, MUFA, PUFA, EPA, DHA, n-3 PUFA, and n-6 PUFA in both men and women. The risk of hypercholesterolemia was not significantly associated with any fatty acid intakes in either sex. The risk of high LDL cholesterolaemia was significantly and positively associated with intakes of TFA, MUFA, PUFA, LNA, n-3 PUFA, and n-6 PUFA in men however, there was no significant association with any fatty acids in women. The risk of low HDL cholesterolaemia was significantly and positively associated with intakes of TFA, MUFA, PUFA, LNA, n-3 PUFA, and n-6 PUFA in men, and was significantly and negatively associated with intakes of MUFA, PUFA, LNA, and n-3 PUFA in women. These results show that dyslipidemia is significantly associated with individual intake of fatty acids, suggesting that fatty acid type may be related to the risk of dyslipidemia.

This study investigated anthropometric and biochemical characteristics, food and nutrient intakes, and changes in body mass index (BMI) of Korean middle age men (40~49 yrs). Data on BMI, anthropometric (height, weight, waist circumference, body mass index, blood pressure), and biochemical (total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, hemoglobin, GOT, GPT) characteristics, food and nutrients intakes, nutrient density, and index of nutrient quality were obtained from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES, 2001, 2005, 2011). Subjects were divided into three groups by year. Weight, BMI, and hemoglobin increased significantly by year. All anthropometric factors except height showed a positive relation with BMI by year. Consumption of barley, chinese noodle, confections, soybean milk, egg, ice cream, pizza, fried foods, banana, coffee, and raw rice wine increased significantly by year. Intake ratios of nutrients except water and fiber were over 100% of KDRI generally. INQ according to intakes of protein, calcium, phosphorus, iron, vitamin A, thiamine, riboflavin, and niacin per 1,000 kcal increased significantly by year. Distribution of BMI status of subjects showed a significant difference by exercise. The findings of the present study show that BMI of subjects increased by year, and intakes of all nutrients except calcium and riboflavin showed aspects of overnutrition by year. Intakes of fruits decreased while intakes of raw rice wine and coffee increased by year. Therefore, practical and systematic nutrition programs are required to maintain optimum BMI and appropriate intakes of nutrients to maintain a desirable lifestyle and improve dietary life.

This study examined intakes of nutrients, carotenoids and polyphenols according to lens turbidity levels among adults visiting a cataract clinic. A total of 102 males and females aged 40 years or higher agreed to participate in the study, and a face-to-face survey interview was conducted to obtain information on general characteristics, health behaviors, and dietary intakes of each participant. The dietary data were collected by a food frequency questionnaire which was previously validated in a Korean population. In addition to essential nutrients, intakes of a total of 10 carotenoids and polyphenols were calculated based on the tables of food functional composition developed by National Academy of Agricultural Science. The subjects were divided into 3 groups according to turbidity levels (< 16, ${\geq}16$ and < 25, ${\leq}25$), and health behaviors and dietary intakes were compared among the turbidity groups. Data showed seemingly higher energy intake and lower dietary antioxidant (i.e., vitamin A, ${\beta}$-carotene, lutein, zeazanthin, lycopene, cryptozanthin) intakes in the highest turbidity group. However, no statistically significant findings were found in all the comparative analysis on characteristics of health behavior and intakes of nutrients, carotenoids and polyphenols. The current study findings should be cautiously interpreted in consideration of several limitations including a cross-sectional study design, a small sample size, uneven sample size distribution across turbidity groups, and limited generalizability due to using a convenience sample. Therefore we cannot conclude that the risk of cataract is unrelated with dietary antioxidant intakes based solely on the results of this study.

The number of school lunch-supported children who belong to low-income families has been rapidly increased in Korea. This study was aimed at evaluation of nutritional status of school lunch-supported elementary school children. One hundred school lunch-supported children and 119 non-supported children of fourth to sixth year class in 3 elementary schools in Gyeongbuk rural area were selected, and surveys were conducted twice, i.e., once during school term and once during summer vacation in 2006. Food consumption survey during school term was carried out through an interview by dieticians at school-lunch time using a 24-hour recall method, and the survey during summer vacation conducted by recording food intakes for three days by children. Nutrient intakes were calculated using CAN-Pro 3.0 program. School lunch-supported children showed higher rate of skipping breakfast and rather irregular meal time as compared to non-supported students. Eating alone was more frequent in school lunch-supported children than in nonsupported children. The average nutrient intakes and nutrient adequacy ratios were lower in supported children than in non-supported children. During term, percentages of nutrient intakes provided by school-lunch were higher in supported children than in non-supported children. Intakes of energy nutrients were within acceptable macronutrient distribution ranges, but proportion of carbohydrate intake increased during vacation. Analysis of patterns of food intakes based on major food groups (dairy, meat, grain, fruit, vegetable) indicated that meals during term were more balanced as compared to meals during vacation. In conclusion, food behaviors and nutrient intakes of school lunchsupported children were inferior to those of non-supported children during term and during summer vacation. They were provided with more nutrient intakes from school lunch during term as compared to non-supported children. Therefore, it is necessary not only to keep meal support program during vacation but also to provide a proper nutrition education as a part of school lunch program to improve nutritional status and food behaviors of school lunch-supported children.

The purpose of the present study was to evaluate the characteristics of nutrient intakes of adults aged 20-64 years in Daegu and Gyeongbuk areas in comparison with Seoul and the whole nation. Data from the 1st (1998) to 3rd (2005) Korean National Health and Nutrition Examination Survey (KNHANES) were used. Total numbers of subjects were 296-369 from Daegu and 307-447 from Gyeongbuk while 1076-1244 from Seoul and 5436-6852 from the whole nation. Average energy intakes (men; 2,386, 2,581, 2,305 Kcal, women; 1,937, 1,981, 1,804 Kcal in 1998, 2001, 2005, respectively) of the subjects from Daegu were higher than those from Gyeongbuk (men; 2309, 2267, 2487 Kcal, women; 1,851, 1,845, 1,901 Kcal) and those from Seoul in 1998 and 2001 but not different from those in 2005. Energy from carbohydrate was consistently higher in the subjects from Daegu and Gyeongbuk than in those from Seoul from 1998 to 2005, when the subjects whose carbohydrate energy was over 70% comprised 34 to 58% of the total in the two regions. In 2005, the average intakes of calcium of women and men from Daegu were 512 and 573 mg, iron, 12.8 and 16.6 mg, sodium, 4,650 and 5,951 mg, potassium, 2,585 and 3,152 mg, vitamin A, 823 and 1,038 ${\mu}$gRE, thiamin, 1.10 and 1.43 mg, riboflavin, 1.08 and 1.33 mg, and niacin. 15.4 and 19.3 mg, and vitamin C, 94 and 105 mg and these intakes were not very different from those from Gyeongbuk except higher sodium intake of the Gyeongbuk subjects. Nutrients of which the intakes were over 50% lower than EAR were calcium and riboflavin and those about 30% lower than EAR were iron in women, vitamins A and C in men and women from Daegu and Gyeongbuk. From the present results, it is concluded that high dependence on carbohydrate as energy source and low calcium intake in adults of Daegu and Gyeongbuk are serious and that low intakes of riboflavin, iron and vitamins A and C need to be improved. But changes in the intakes of total energy and other micronutrients from 1998 to 2005 were not reliable enough to judge the regional nutrition due to large variations during this period. The present study also provides the adults' nutrient intakes separated by sex and age groups in the three regions which could be readily used for setting up the nutrition policy for the adults in the regions.

Objectives: This study evaluated dietary intakes of total fat and fatty acids among the Korean adult population. Methods: This cross-sectional study used the 2016-2017 Korea National Health and Nutrition Examination Survey data. A total of 10,772 subjects aged ${\geq}19y$ for which dietary data were available were selected. Data pertaining to energy and nutrient intakes were obtained by a 24-h recall method. Total fat and fatty acids intakes were evaluated based on the Acceptable Macronutrient Distribution Ranges (AMDR) of 2015 Dietary Reference Intakes for Koreans by sex and age groups. All statistical analyses accounted for the complex sampling design effect and sampling weights. Results: The mean intakes of energy and total fat were 1,952 kcal (95% CI: 1928-1977) and 46.1 g (45.2-47.1), respectively, and about 21% of the energy was obtained from fat in this study population (21.7% in men and 20.2% in women). The mean percentages of energy from saturated, monounsaturated, and polyunsaturated fatty acids were 6.4%, 6.7%, and 5.2%, respectively. About 18% of adults exceeded the AMDR for fat (30% of energy), whereas 37.6% exceeded the AMDR for saturated fatty acids (7% of energy). The proportions of subjects who consumed more than the AMDR for fat and saturated fatty acids decreased across age groups in both sexes. Among young adults (19-29 y), about 63% of the subjects obtained ${\geq}7%$ of their energy from saturated fatty acids. About 61% of older adults obtained less than 15% of their energy from total fat. Conclusions: Increased intake of fat energy was prominent in saturated fatty acids. Our findings suggest current information on total fat and fatty acids intakes in Korean adults and can be used to provide dietary guidelines for the improvement of public health.

Dietary Variety Score (DVS) or Nutrient Adequacy Ratio (NAR) offers a way of comparing eating habits across populations and across countries. This study compared nutrients intakes, food intakes, DVS, and NAR between Korean and US adults using the large national survey data. 4662 Korean adults (men: 2201, women: 2461) aged 20-49 years were selected from the 'Korean National Health and Nutrition Survey,2001' and 4199 US adults (men: 2127, women: 2072) aged 20-49 years were selected from the 'US National Health and Nutrition Examination Survey (NHANES IV,1999-2002)'. The total plant food intakes were high in Korean adults, but the total animal food intakes were high in US adults. Intakes of legumes and nuts, vegetables and mushrooms were higher in Korean than in US adults. On the other hand, intakes of meats, milk and dairy products of US adults were higher than Korean. Beverage intakes were 8 - 10 times higher in US adults than in Korean. The mean DVS of Korean men and women were higher than US men and women. Intakes of fat, calcium and vitamin $B\_{2}$ of US adults were 1.5 - 2 times higher than those of Korean, which could probably related to larger consumption by US adults on milk and dairy product. While the intakes of carbohydrate and vitamin C of the Korean were higher than the US adults, which could presumably related to higher grain and vegetable consumption. Percent energy intakes from carbohydrate, protein, and fat were $64.1\%$, $15.8\%$, and $20.1\%$ for Korean men, $52.4\%$, $15.0\%$, and $32.6\%$ for US men, $65.9\%$, $14.9\%$, $19.2\%$ for Korean women, and $52.1\%$, $14.7\%$, $33.2\%$ for US women respectively, which showed higher $\%$energy from carbohydrate in Korean and higher $\%$energy from fat in US adults. Most nutrient intakes except energy and vitamin C expressed as $\%$RDA were higher in US than in Korean adults. Mean Adequacy Ratio (MAR) of US men and Korean men were both 0.85, while the MAR was 0.81 for Korean women,0.79 for US women. The Korean women's diet showed more diverse and adequate than the US women's diet.

The purpose of this study was to investigate the effects of relating factors on the nutrient intakes in elderly people aged over 85 years residing Namhae Kyungnam. The subject of this study was composed of 24 males and 76 females, the average age being 88.9±4.0 years old. The consumption of energy and most other nutrients was higher in females than males. There were significant positive correlations the education level, pocket money, self-perception of health and happiness, frequency and regularity of meal with nutrient intakes in elderly males and females. The smoking was negatively correlated with protein and niacin intakes(p<0.05). The alcohol drinking and sleeping hours were not significantly correlated with nutrient intakes.

The purpose of this study was to investigate the eating patterns, nutrient intakes, blood levels, and health status of male college students in Seoul according to body mass index (BMI). In this study, we classified subjects into normal weight (n=240), under weight (n=11), and obese (n=46) groups according to BMI. The weight and BMI were significantly higher in the obese group compared to other groups (p<0.0001). The obesity was associated with overeating and frequent eating. The under weight group showed significantly higher consumption of fast food, snacks, and fried foods compared to the other groups (p<0.05). The intakes of milk, meat, fish, eggs, and fried food and preference ratios were higher in the obese group (p<0.05). The male college students in this study showed insufficient intakes of calories, vitamin C, folic acid, and calcium. The plasma LDL-cholesterol levels in the obese group were higher compared to the other groups. In conclusion, intake of nutrients among male college students is found to be insufficient and requires nutritional education. The under weight group showed regular eating habits and increased nutrient intake. The obese group was shown to need more exercise with higher intakes of vegetables and fruits.
