Purpose: Number of the old-old elderly is rapidly increasing in Korea, but it is unclear whether there are differences between old-old and young-old elderly in nutritional status, nutrient intakes and health status. The gender differences in Korean elderly in these conditions also remains unknown. This study, therefore, investigated gender-associated differences in nutritional, health status and nutrient intakes and how they are related among young-old and old-old homebound elderly. Methods: Two hundred and eighty elderly who were attending a local elderly welfare center were recruited. Evaluation included demographic, nutritional and health status related data, nutritional intakes, and life style related factors including physical activity. Results: Of the 280 subjects, old-old were 147 (52.5%) and young-old were 133 (47.5%). Male old-old elderly had more often abdominal obesity than female old-old, but male old-old more often had malnutrition than female old-old. There were few differences in nutrient intakes between old-old male elderly and female elderly after energy intakes were controlled. Male old-old more often had less intake of beta carotene and Vitamin A than female old-old. On the other hand, male old-old elderly more often had hypercholesterolemia and hypertension than male young-old. Conclusion: Male old-old may be at a greater health and nutritional risk than female old-old. Targeted nutritional intervention for male old-old emphasizing antioxidant nutritional intakes may be warranted.

This study was carried out in order to investigate the status of food and nutrient intakes depending on the types of chronic disease of the elderly at welfare centers in Seoul. The total number of subjects was 299 elderly over the age of 60 (82 men and 217 women); they were grouped by the disease status: normal, cardiovascular disease (CVD), diabetes mellitus (DM) and arthritis patients groups. The dietary intakes were obtained by a 24-hour recall and analyzed by CAN-Pro 4.0; they were then compared with the dietary reference intakes for the Korean (KDRIs). In the results of anthropometric data according to chronic disease, the waist circumference of the normal group in males and females was lower than the other groups; in particular, the normal female group showed a lower level of waist-hip ratio, body mass index (BMI) and body fat % than those of the other groups. The arthritis group showed a higher intake of milk products than the other groups (p < 0.05); consequently, calcium intake was significantly higher than that of the other groups (p < 0.001). Vitamin A intake in the arthritis group was significantly higher than the intake in the normal and DM groups (p < 0.01). Normal and arthritis groups showed significantly higher intake of zinc and copper than the CVD group (p < 0.01). In general, about 80% of the subjects in this study revealed insufficient intakes of riboflavin, vitamin C, calcium, dietary fiber, vitamin D, biotin and potassium, compared with the estimated average requirement (EAR) or adequate intake (AI). However, sodium intake of all groups was higher than the AI of KDRIs. In conclusion, nutrient intake, according to the chronic disease, showed significant difference in some of the micronutrients, vitamin A, Ca, Zn and Cu. Therefore, we suggest that dietary guidelines, such as reducing the intake of salty foods and sweet drinks and increasing the intake of foods with sufficient calcium, vitamin D and vitamin C, are necessary to the improvement of eating habits for the elderly.

This study was conducted to measure and evaluate the food and nutrient intakes of the people living near the nuclear plant and to investigate the relationship between the household income level and the food and nutrient intake patterns. A total of 552 cases (263 males and 289 females) were surveyed during the period from April 1 to December 21 of 2005. Dietary intake was measured by means of the 24-hour recall method. The data were analyzed using SPSS Windows (ver. 14.0). The household income level of the subjects was classified into two groups : Low income group (LIG; $\leq$2,000,000 won) and high income group (HIG; > 2,000,000). The subjects at large had less energy and nutrient intakes than did the population in town and village who participated in the 2005 National Health and Nutrition Survey. The intake of calcium, zinc, vitamin A, riboflavin, vitamin $B_6$, vitamin C, and folic acid was less than the Estimated Average Requirement in case of $50{\sim}95%$ of the subjects. The LIG consumed less beans, vegetables, fruits, meats, and beverages than did the HIG in male, while the LIG consumed less eggs and beverages than did the HIG in female. The LIG consumed less nutrients than did the HIG in male, except for carbohydrate, while the LIG consumed less nutrients including zinc, vitamin A, riboflavin, vitamin B6, vitamin C, folic acid than did the HIG in female. In addition, the LIG had higher percentage energy consumption from carbohydrate. These results suggest that higher food and nutrient intake is associated with higher income.

This study was conducted to compare nutrient intakes regarding stages of change in dietary fiber increasing behavior. Subjects were consisted of healthy 383 college students (2S0 females and 133 males) in Kyunggi-Do. Stages of change classified by an algorithm based on 6 items were designed each subjects into one of the 5 stages: precontemplation (PC), contemplation (CO), preparation (PR), action (AC), maintenance (MA). Nutrient intakes were assessed by 24-hr recall method. Regarding the S stages of changes, PR stage comprised the largest group $(39.4\%)$, followed by AC $(33.7\%)$, MA$(14.6\%)$, PC$(7.6\%)$, CO$(34.7\%)$. Female were more belong to either AC or MA. The higher stage of change in dietary fiber increasing behavior, the higher self-efficacy. In all male and female, there were no differences in energy, protein, monounsaturated fatty acids, polyunsaturated fatty acids and cholesterol intakes across the 5 stages. But, fiber, postassuim (K), vitamin A and vitamin C intakes of AC or MA were higer than those of PC, CO and PR $Energy\%$ from fat of $PR(25.4\~26.5\%)$ was higher than $20\%$, and those of AC and MA was lower than the other groups. Dietary P/S and ${\varepsilon}6/{\varepsilon}$ 3 ratios of AC and MA were similar to the recommended ratio. Female of PR had the most total saturated fat and palmitic acid and those of MA had the least. Male of PR had the least $\alpha-LNA\;({\varepsilon}3)$ and total ${\varepsilon}3$ fatty acids and those of MA had the most. In male and female in AC or MA, fiber and K intakes from breakfast, dinner and snack and vitamin C intakes from all meals were higher than those of the other stages. These results of our study confirm differences in stages of change in fiber intake in terms of nutritional status. To have lower $energy\%$ from fat, higher intakes of K, fiber and vitamins, desirable ratio of dietary fatty acids, it needs consistent nutritional education leading to the AC or MA of fiber increasing behavior.

This survey was carried out to study the difference of nutrient intake, food behavior and health condition according to food intake diversity in the elderly(age 65 year over and 74 year under) in a local city. A diet survey with one day 24-recall method was used for 216 subjects(65 male & 151 female). Based on a food intake diversity examination, including an evaluation of KDDS(Korean's Dietary Diversity Score ; counts the number of food groups consumed daily from total five food groups(cereal, meat, vegetable, dairy, and oil groups)), Meal Balance(apply the KDDS at breakfast, lunch and dinner), and DVS(Dietary Variety Score ; total number of foods consumed), subjects were clustered according to food intake diversity. Food intake diversity patterns of male and female clusters were classified each into threes(Male-low group(24.6%), middle group(33.8%), and high group(41.5%)/Female low group(41.7%) middle group(37.1%), and high group(21.2%). The averages of KDDS, Meal Balance and DVS were 3.0, 7.5, 14.8 in the male middle group, and 4.5, 10.2, 25.7 in the male high group, 2.7, 6.3, 14.3 in the female low group, 4.0, 8.6, 18.0 in the female middle group, and 4.5, 10.5, 25.7 in the female high group respectively. The average dairy intake of nutrients below the RDA were energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$and niacin in the male low group, energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$in the male middle group and energy, Ca, Vitamin B$_2$in the male high group but a little. Also the female low group had intakes of all nutrients except Vitamin C, the middle group had intakes of energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$, and the female high group had intakes of energy, Ca, Vitamin A below the RDA respectively. Food intake diversity increasing, nutrient intake, food behavior and health condition proved to be good. This study explored the usefulness of cluster analysis in identifying food intake diversity of three groups of the elderly in relation to their nutrient intake, food behavior and health conditions.

Objectives: Use of dietary supplements containing vitamins and minerals is growing in Korean adults, especially in pregnant and lactating women. Vitamin and mineral supplements are available in different composition and in a wide range of contents. The purposes of the study were to examine nutrient composition and content of vitamin and mineral supplements for pregnant and lactating women and assess their appropriateness as dietary supplements. Methods: Information on the name, manufacturer, nutrient composition, and usage of vitamin and mineral supplements for pregnant and lactating women were obtained from the homepage of the Food Safety Information Portal managed by the Ministry of Food and Drug Safety, and Korean Index of Medical Specialties. A total of 264 products were identified. Results: Among 264 products, 26.1% were single nutrient products, and 73.9% were multinutrient products. The most commonly included nutrient was iron (70.1%), folic acid (66.3%), vitamin $B_{12}$ (45.8%), vitamin C (38.6%), and vitamin $B_6$ (38.6%). Although more than 50% of products contained nutrients less than 150% of Recommended Nutrient Intakes or Adequate Intakes for daily use, some products contained inappropriately high amounts of nutrients. When a maximum daily dose of supplements was taken as described on the label, iron in 73 products (39.5%), folic acid in 14 products (8.0%) were likely to be consumed in amounts greater than Tolerable Upper Intake Levels. Most products were assessed as inappropriate for pregnant women due to the possibility of excessive intake of vitamins or minerals when compared with Dietary Reference Intakes. Conclusions: Pregnant and lactating women need to carefully select dietary supplements containing adequate amounts of vitamins and minerals. Nutritionists should provide guidelines regarding selection of appropriate vitamin and mineral supplements for pregnant and lactating women.

The purpose of this study was to investigate the effects of preschool children's taste preferences on their intake of nutrients and the degree of dental caries. The subjects were 126 preschool children (boys 62 and girls 64) in Daegu area. Their taste preferences and food intake were investigated and their teeth were also examined. The energy intake of boys (1550 kcal) were significantly higher than that of girls (1441 kcal). Daily dietary intakes of nutrients-except niacin and vitamin C-were higher than those of RDA. Vitamin B$_1$ intake of the group preferring a salty taste was significantly lower than that of the other group (p<0.05). Vitamin B$_2$ intake of the group preferring a salty taste was significantly higher than that of the other group (p<0.05). Vitamin C intake of the group preferring a hot taste was significantly higher than that of the other group (p<0.05). The group with a preference for sweet had more experiences of dental caries and more decayed teeth than the other group, but which is not significant. The experiences of dental caries were negatively correlated with protein intake (p<0.01). The decayed teeth were negatively correlated with energy and protein intakes (p<0.01). Our data suggested that taste preferences are associated with vitamins intake and the degree of dental caries in preschool children. It means the sweet preference increased the experiences of the dental caries.

It is generally accepted that diet modification provides beneficial effects on the management of diabetes. In the present study, we evaluated the effects of diet modification on nutrient intake and quality of life in a large sample of diabetic patients. This study was conducted using data from the Korea National Health and Nutrition Examination Survey IV and V (2007-2010). A total of 2,484 of diabetic patients were included in the analysis. Then, we compared the overall quality of dietary intake between diabetic patients with diet modification and those without dietary modification. The result showed that subjects on diabetic diet (DDG) showed lower levels of total cholesterol, triglyceride, and AST before and after the adjustment for covariates (all p < 0.05). The results of nutrient assessment showed that DDG had lower intakes of total energy, fat, and carbohydrate (all p < 0.05), but higher intakes of energy from protein, vitamin B1, vitamin B2, niacin and vitamin C than NDG. (all p < 0.05). In addition, nutritional adequacy ratio of calcium and vitamin B2 were significantly higher in DDG than those in normal diet group (NDG) (p < 0.05). However, we observed no significant differences in quality of life between two groups. In conclusion, diet modification in diabetic patients seemed to be effective to improve blood lipid profile and the adequacy of nutrient intake without sacrificing the quality of life.

Purpose: The purpose of this study was to determine trends in dietary vitamin E intakes and contributing food groups among Korean adults. Methods: This study included 66,695 subjects aged ${\geq}19years$ who completed a nutrition survey as part of the Korea National Health and Nutrition Examination Survey (1998, 2001, 2005, 2007~2009, 2010~2012, 2013~2015). We estimated individual daily intakes of ${\alpha}-$, ${\beta}-$, ${\gamma}-$, ${\delta}-tocopherol$, and total vitamin E by linking food consumption data with a vitamin E database of commonly consumed foods. Results: Daily vitamin E intake significantly increased from $6.4mg\;{\alpha}-TE/d$ in 1998 to $7.7mg\;{\alpha}-TE/d$ in 2013~2015 (p for trend < 0.0001) among men as well as from $5.4mg\;{\alpha}-TE/d$ in 1998 to $6.5mg\;{\alpha}-TE/d$ in 2013~2015 among women (p for trend < 0.0001). However, the intake of vitamin E was lower than the adequate intake (AI) of Dietary Reference Intakes for Koreans 2015 (2015 KDRI). In 2013~2015, men consumed 6.5 mg/d of ${\alpha}-tocopherol$, 0.5 mg/d of ${\beta}-tocopherol$, 6.0 mg/d of ${\gamma}-tocopherol$, and 3.9 mg/d of ${\delta}-tocopherol$, whereas women consumed 5.7 mg/d of ${\alpha}-tocopherol$, 0.4 mg/d of ${\beta}-tocopherol$, 4.8 mg/d of ${\gamma}-tocopherol$, and 2.8 mg/d of ${\delta}-tocopherol$. The major food groups contributing to vitamin E intake were vegetables (men: 23.3%, women: 22.7%), grains (men: 14.5%, women: 13.9%), and eggs (men: 13.0%, women: 12.5%). Conclusion: This study provides scientific evidence for vitamin E intake in Korean adults. Since the current intake of vitamin E was lower than the reference intakes set by 2015 KDRI, dietary vitamin E intake should be monitored regularly among Korean adults.

In order to investigate if the employment of housewives may affect the nutritional status of their family members, an analysis was made for the data of 2001 Korea National Health and Nutrition survey. Housewives aged 20 or over were divided into two groups of the working (W, 44.3%) and the non-working (NW, 55.7%), and household income levels were divided into 4 groups of low, middle, high, and high above according to the minimum cost of living in the year of 2001. Nutrient intakes were assessed by using dietary recommended intakes for Koreans of 2005. Working housewives showed similar levels to those of non-working housewives in most nutrients intakes except energy and vitamin C. However their families excluding housewives of W, than those of NW, took less protein, calcium, iron, potassium, vitamin A, thiamin, riboflavin, niacin, and vitamin C when assessed as % of recommended intakes and took more sodium. Such differences were very strong in children and adolescents, and in the middle income households. More % of the families of W than those of NW consumed nutrients below the estimated average requirements. Percents of hypertension classified by both systolic and diastolic blood pressure were higher in adult family members of W than in those of NW. This tendency seemed to be more significant in the family members aged 30 to 49. Both obesity and under-weight rates of school children ($7{\sim}12\;yrs$) in W were higher than those in NW. The above resuIts suggested that employment of housewives could have negative influences on the nutritional status of their family members, especially of their children and in the middle income class.
