This study was performed to assess the nutritional status of low income elderly women aged ${\geq}$65 years residing in Gyeongnam Masan (n=124). Nutrition intakes, food intake frequency, and health-related behaviors including smoking, drinking, and exercise were investigated. Nutrition intake was calculated by the 24-hour recall method using CAN-pro (ver. 3.0). Average daily intakes of energy were $1,142.3{\pm}39$ kcal (71.4% of EER) in subjects aged 65~74 years and $1,071.0{\pm}41.7$ kcal (66.9% of EER) in subjects aged ${\geq}$75 years and the subjects consumed energy less than both 75% of estimated energy requirement (EER). The proportions of energy derived from protein, fat, and carbohydrate were 15.4:15.5:70.6 (aged 65~74 years), and 15.3:13.4:70.8 (aged ${\geq}$75). Nutrients consumed at less than estimated average requirements (EARs) were Ca (60.4%), P (98.4%), Zn (91%), vitamin E (48% of adequate intake, AI), vitamin $B_1$ (63.3%), vitamin $B_2$ (54%), niacin (87.7%), vitamin C (62.5%), and folate (50.5%). Especially, the intakes of Ca (58%), vitamin E (41% of AI), vitamin $B_1$ (60%), vitamin $B_2$ (50%), folate (46.5%), and vitamin C (54%) were 75% less than the EAR for people aged ${\geq}$75 years. According to the food intake frequency survey, the intakes of calcium, milk, fruits, and vegetables were very poor. In conclusion, this study suggests that a nutritional support program for elderly women of low socioeconomic class must be provided by the government to improve the quality of remaining life.

The purpose of this study was to investigate children's nutrient intakes by school lunch. Evaluation of nutrient intakes by school lunch for three days was conducted with 86 children in urban and 64 children in rural of Jeonbuk area. The results of this study were as follows. 1) With respect to amounts of provided nutrients in school lunch, CPF (carbohydrate : protein : fat) energy ratio was 48.6 : 19.7 : 31.6 in urban and was 46.7 : 20.5 : 32.7 in rural. Compared to 1/3 RDA (RDA) of children for 10-12 years, folic acid and zinc were provided below 50 % of RDA. Protein, fat, phosphorus, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C and vitamin E were provided above 125 % of RDA. There were no differences in amounts of provided nutrients-except calcium, vitamin A, vitamin $B_6$, folic acid and zinc-between urban and rural. 2) With respect to amounts of nutrient intakes, CPF energy ratio was 51.1 : 17.4 : 31.5 in urban and 47.5 : 19.7 : 32.7 in rural. Compared to RDA, folic and zinc were below 50 % of RDA. Iron and vitamin $B_6$ were below 75 % of RDA. Protein, fat, phosphorus and vitamin E were above 125 % of RDA. There were significant differences in nutrient intakes between urban and rural. The children in rural showed higher levels of nutrient intakes-energy, carbohydrate, protein, fat, calcium, phosphorus, iron, zinc, vitamins and folic acid-compared to those of children in urban. These results suggest that programs are needed for providing adequate nutrient intakes for children in school lunch and for improving nutrient intakes of children in urban.

This study was performed to investigate Apolipoprotein E phenotypes and the relationship among lipid levels, nutrient intakes, lifestyles and risk factors between subjects with and without hyperlipidemic risk. The data were collected from 675 industrial male workers who had completed annual medical examination. Compared to the normal group, the hyperlipidemic risk group in Apo E3 and E4 had significantly higher BMI (p < 0.05) and showed significantly higher body fat (%), waist circumference and WHR in all types of Apo E (p < 0.05). In addition, the hyperlipidemic risk group had significantly higher total cholesterol, LDL-cholesterol, triglyceride and AI than the normal group in all types of Apo E (p < 0.05). Intakes of protein, calcium, phosphorus, iron, vitamin A, vitamin B1, vitamin B2, vitamin C and niacin in Apo E3 were significantly lower in the hyperlipidemic risk group than in the normal group (p < 0.05). In the logistic regression analysis, after adjustment for other factors, Apo E2 + E4, waist and WHR were the significant risk factors associated with hyperlipidemia, but protein intakes were associated with significantly lower risks of hyperlipidemia (p < 0.05). In conclusion, genetic factor (Apo E2 or Apo E4), anthropometric index and nutrient intake seem to influence hyperlidemic risk. Further studies and efforts will be needed to evaluate the independent relationships among hyperlipidemic risk factors.

It has been reported that cigarette smoking increases free radical generation, which can also increase lipid peroxides and deplete antioxidants. The purpose of this study was to determine whether cigarette smoking and other lifestyle choices may affect serum lipid peroxide concentrations, serum antioxidant concentrations such as tocopherol and vitamin C, and serum antioxidant enzyme activity such as glutathione peroxidase and superoxide dismutase. Dietary intakes were assessed by 24-hour recall and survey questionnaires from 48 male non-smokers and 52 male smokers. Overnight fasting blood was collected and measured for individual antioxidant status. The daily vitamin C intakes of smokers tended to be lower than those of non-smokers, and the intakes of both groups were under the Recommended Daily Allowance (RDA). Vitamin E intake was sufficient for smokers and non-smokers. Serum lipid peroxide concentrations were no difference among all subjects. The serum $\alpha$-tocopherol concentrations of all subjects were in a normal range, and they were highest in mild smokers (p<0.05). Mean serum vitamin C levels were lowest in heavy smokers (p<0.05). The activities of serum glutathione peroxidase and superoxide dismutase were not significantly different in smokes and non-smokers. In conclusion, smoking did not increase oxidative stress in heathy young men. However, it is desirable for heavy smokers to consume more vitamin C than the RDA sine their serum vitamin C concentrations are relatively low.

Body antioxidant status is an important factor in the prevention of many chronic diseases caused by oxidative stress, especially in the elderly and is affected by health-related habits, such as smoking, drinking and regular physical activity. The aim of this study was to investigate the relationship between these health-related habits and plasma antioxidant status in the elderly. Plasma antioxidant status was examined by determining plasma levels of antioxidant vitamins (vitamin C, A, E, $\beta$ -carotene), total antioxidant status (TAS) and thiobarbituric acid-reactive substance (TBARS) . The subjects included 225 elderly persons aged over 60 yews (63 males, 162 females) living in the Ulsan area. They were interviewed to collect data on their general characteristics and health behaviors such as smoking, exercise and alcohol consumption by means of questionnaires. Their dietary intakes were obtained by means of semi-quantitative food frequency questionnaires (FFQ) The study population was divided into two or three groups according to their smoking, drinking, and exercise status. The ratio of smoker, drinker and exerciser was 16.7%, 31.0% and 44.2% respectively. The dietary antioxidant vitamin intakes were not significantly different among groups of smoking and drinking status, but tended to be higher in non-smokers and non-drinkers than in smokers and drinkers. Plasma vitamin C and $\beta$ -carotene levels were significantly higher in non-smokers, but Plasma vitamin A and TBARS levels were significantly lower in non-smokers than in smokers. Plasma TAS was not significantly different among the smoking groups, but showed a tendency to decrease with an increase in the number of packyear. Plasma vitamin C and $\beta$ -carotene levels of the non-drinkers were higher than those of drinkers and past-drinkers, but plasma vitamin A, C, E, TAS and TBARS showed no difference among the groups of drinker. All vitamin intakes of the exercisers were slightly higher than those of the non-exercisers, but vitamin C intake was significantly higher in female exercisers than in non-exercisers. Plasma $\beta$ -carotene levels were significantly higher in male exercisers and plasma vitamin A, C, E, TAS and TBARS levels tended to be higher in exercisers than in non-exercisers. These results suggested that change to non-smoker, modulation of alcohol consumption and regular exercise could enhance antioxidant defences against reactive oxygen species and might increase the likelihood of a healthier life span.

The increased oxidative stress may play an important role on the pathogenesis of diabetes and diabetic complications, and the blood level of vitamin C and lipid peroxidation in NIDDM patients may be used as an indicator for oxidative stress. However there is only scanty evidence on the blood level of vitamin C in NIDDM patients with or without diabetic complications. The study population consisted of 90 NIDDM patients(diabetes without complication, 48, and diabetes with complications, 42) and 41 normal subjects. The 42 diabetic complications were divided into 3 groups : 15 diabetic nephropathy, 18 diabetic neuropathy, 9 diabetic retinopathy. The anthropometric data and blood biochemical data were studied. The dietary intake was determined by 24 hour recall methods and food frequency questionnaire. The plasma concentrations of MDA and vitamin C were determined by fluorophotometer and HPLC respectively. 1) In blood lipoprotein study, diabetes with complication had higher level of TG than diabetes without complications, while no significant differences in total cholesterol, HDL, and LDL were shown. Diabetic neuropathy had the highest TG level among diabetic complication groups. 2) The intakes of vitamin B complexes(vitamin B$_2$, vitamin B$_{6}$, not vitamin B$_1$) and antioxidant vitamins(vitamin A and vitamin E, not vitamin C) and certain minerals such as iron and calcium in diabetes were not sufficient but the intakes of energy, protein, niacin, and phosphorus in diabetes were sufficient. The dietary intakes between diabetes with-and without complications were not significantly different. Among diabetic complications, the diabetic retinopathy had the lowest intake of vitamin B$_2$ and B$_{6}$(p < 0.05). the diabetic neuropathy or nephropathy consumed extremely low amount of vitamin A. 3) The MDA concentrations of NIDDM was significantly higher than that in controls(p < 0. 05) while no significant difference in the MDA concentration between with and without complications was shown. Although there were no statistical differences, the diabetic nephropathy and diabetic neuropathy showed the higher concentration of MDA than the diabetes without complications or diabetic retinopathy. 4) The plasma concentration of vitamin C in controls was higher than that in diabetes(p < 0.05) while the plasma vitamin C in diabetes with and without complications were similar. In diabetic complications, no differences in plasma vitamin C concentration of three groups were shown. This study showed that the oxidative stress in NIDDM patients was highly increased and the vitamin C reserve was significantly depleted, as compared with normals, although their intakes of vitamin C met korean RDA, which means that diabetes need more vitamin C intake to decrease oxidative stress in NIDDM patients.nts.

Body antioxidant status is an important factor for the prevention of many chronic diseases in the elderly. This study was done to investigate antioxidant status and its relationship to immune response by measuring plasma cytokine (IL-2 and IL-6) levels in elderly women. Subjects were 76 elderly women aged over 60 years, visiting Jangwhi Social Welfare Center of Seongbook-Gu in Seoul. Subjects were divided into 3 groups according to age (< 65, 65 - 74, > 75). Dietary intakes were assessed by semi-quantitative food frequency questionnaires (SFFQ). Plasma vitamin C level was measured by 2,4-dinitrophenylhydrazine method and plasma levels of vitamin E, A and ${\beta}$-carotene were measured by HPLC. Plasma levels of IL-2 and IL-6 were determined with a solid phase sandwich enzyme linked-immuno-sorbent assay (ELISA) using commercial kits. The average intakes of antioxidant vitamins were 96.3mg (137.5% of RDA) for vitamin C and 523.3 ${\mu}$gRE (74.8% of RDA) for vitamin A in elderly women. All of the average plasma levels of antioxidant vitamins were within normal range. However the percentage of the elderly women with deficiency plus marginal values were 7.9% in vitamin C, 9.2% in vitamin A and 7.9% in vitamin E. Plasma levels of IL-2 and IL-6 were 27.1${\pm}$7.1pg/ml and 5.9${\pm}$5.3pg/ml in elderly women. Correlation data showed that plasma IL-2 level was negatively correlated with plasma vitamin C level. In addition, IL-6 level was also negatively correlated with plasma vitamin C, A and E levels, respectively. There was a significant positive correlation between erythrocyte thiobarbituric acid-reactive substance(TB-ARS) level and plasma IL-2 or IL-6 levels. In addition, erythrocyte TBARS level showed a significant positive correlation with plasma total antioxidant status (TAS) level and a significant negative correlation with plasma vitamin C level. Overall results might imply that the decreased levels of antioxidant vitamins result in an increase in oxidative stress and thereby increase cytokine production such as IL-2 and IL-6. However further research is required to elucidate these relationships.

Body antioxidant status is an important factor for the prevention of many chronic diseases in the elderly. This study was done to evaluate the nutritional status of antioxidant vitamins of the elderly by determining their intakes and plasma levels. It was also aimed to compare daily intakes and plasma levels of antioxidant vitamins by sex of age. Subjects were 225 elderly persons aged over 60 years old (63 males, 162 females) living in Ulsan area. Subjects were divided by groups according to age(＜ 65, 65－74, 75) and sex. Dietary Intakes were assessed by semi-quantitative food frequency questionnaires(FFQ). Plasma Vitamin C level was measured by 2,4-dinitrophenylhydrazine method and plasma levels of vitamin E, A and ${\beta}$-carotene were measured by HFLC. The average intakes of vitamin C were 104.9g(150% of RDA) and 104.4g(149％ of RDA) in the elder1y males and females, respectively. Vitamin C intake of the elderly was significantly decreased by aging but not different by sex. The average intakes of vitamin A were 678$\mu\textrm{g}$RE(96.9% of RDA) and 604$\mu\textrm{g}$:RE(86.2% of RDA) in elderly males and females, respectively. The average levels of Plasma vitamin C were 6.22mg/L and 11.45mg/L in the elderly males and females, respectively. Those levels are within normal range(6-20mg/L). However the percentage of the elderly males with deficiency(＜ 2mg/L) and marginal level(2-4mg/L) of vitamin C were 27.4% and 16.1%, respectively. Plasma retinaol levels were 0.39mg/L for the elderly males and 0.37mg/L for the elderly females, which were within normal range. But the percentage of subjects with marginal level were 28% ill both males and females. Plasma ${\alpha}$-tocopherol levels of the elderly were lower than normal range(5-12mg/L). Plasma levels of vitamin C, E and ${\beta}$-carotene, except retinol, were significantly higher in the elderly females compared to males and showed significant decrease by aging.

The purpose of this study was to investigate the difference of general characteristics, menopause status, dietary patterns and nutrient intakes between women aged from 30 to 65 years old with a hypercholesterolemia group and normocholesterolemia group. The subjects were classified as belonging to the hypercholesterolemia group or normocholesterolemia group barred on The Guidelines for Korean Hyperlipidemia. Dietary intakes of fatty acids were measured by means of a 24-hr recall method with food models and measuring tools. We analyzed both data sets together using analysis of variance chi-square test and student's t-test(SPSS for WINDOWS, version 7.5). Significance was defied as a p value < 0.05. The results obtained are summarized as follows. Mean age and BMI of the hypercholesteroemia group were significantly higher than those of the normocholesterolemia group. Intakes of cereal, vegetables, mushrooms and sea food in the normocholesterolemia group were significantly higher than those in the hypercholesterolemia group. Most of the nutrient intakes were not significantly different between the normocholesterolemia group and the hypercholesterolemia group. However, vitamin E intake of the normocholesterolemia group was significantly higher than that of the hypercholesterolemia group. There was a significant negative correlation between vitamin E intake and serum TC(r = -.363, p < 0.001) and LDL-C(r = -.359, p < 0.001). In addition, Serum TG had significantly correlation with carbohydrate(r = 0.137, p < 0.001) and vitamin E intake(r = -0.134, p < 0.001). Therefore, women who suffered from hypercholesterolemia were recommended to control body weight, and to consume foods containing high vitamin E and foods containing high dietary fiber such as vegetables, mushrooms, and sea food.

This study was investigated nutrient intakes and dietary evaluation index of the healthy subjects over 85 of Sunchang County to explore the improved dietary pattern for healthy aging of the elderly. The survey was conducted by personal interview to 161 elderly subjects (59 males and 102 females over 85) in 2006, and their daily dietary intake was assessed by 24-hr recalls and weighing one meal. The daily energy intakes of males were 1,335 ${\pm}$ 67 kcal, and those of females were 1,095 ${\pm}$ 38 kcal comprised of 66.8% and 68.4% of the EER for the age group of 75. The proportions of energy from carbohydrate : protein : lipid were 70.7 : 14.6 : 14.6 for males and 68.6 : 14.0 : 17.4 for females. The average protein intakes were 95.4% for males and 85.0% for females of RI, and the average calcium intakes were 54.3% for males and 43.6% for females of RI. The daily vitamin intakes were below 70% except vitamin A, vitamin $B_6$, and vitamin E. The proportion of the relative risk groups of protein, phosphate, iron and vitamin A ranged 40-49% of RI over 75 year groups. The other nutrient intakes showed that there were over 50% risk groups. Especially for nutrients such as calcium, vitamin $B_1$, vitamin $B_2$, vitamin C, folate and niacin over 70% of the subjects were under risk. The median value of all nutrient intakes did not reach AI. The INQ of nutrients were over 0.8 except for folate and vitamin C. Calcium intakes were relatively low and needed attention. However, the ratio of calcium and phosphate showed 1 : 1.6, which appeared to be superior to the other districts. The DVS were higher as the dietary balance scores, KDDS were higher, and the groups with high KDDS had high intakes of nutrients compared to the groups with low KDDS. The high risk groups as judged by simple nutrition screening test had lower nutrient intakes than the groups of middle risk or low risk groups. The subjects in Sunchang area had relatively low intakes of several nutrients. However, judging from the desirable patterns of the energy proportion from three major nutrients, ratio of calcium and phosphate and INQ of nutrients there is a possibility that extended healthy aging might be related to the quality of nutrients and relative ratio between nutrients. To improve nutrient status of the elderly of the surveyed area further application involving KDDS and DVS appeared to be required.
