This study was carried out with 200 students of Chungbuk National University to investigate their dietary behavior and calcium intake and to find out variables among general characteristics of subjects which influence dietary behavior and calcium intake. Questionaires and interviews were used for data collection. The results obtained were as follows: 1) Dietary behavior of college students were not desirable as a whole. The percentages of skipping breakfast and irregular meal among students were over one third, respectively. Especially students living alone skipped breakfast more frequently, took their meals more irregularly, and their eating frequencies of 6 food groups were lower compared to students eating at home. 2) Calcium intake was significantly different according to gender. Mean calcium intake of male students was 744.0 mg/day and that of female students was 480.8 mg/day. Average %RDA of calcium intake of female students was 68.5%. Resource food contributing to calcium intake in the first order was milk, next was yogurt, Small anchovies, kimchi made with Chinese cabbage, ice cream and soybean curd in that order. From the results of this study, we found that the students living alone and female students are exposed to high risk of poor dietary behavior and undernutrition of calcium. In conclusion, nutrition education programs for them are required as soon as possible.

This study was performed to investigate the characteristics of nutrient intake according to metabolic syndrome in Korean elderly. Data on 1,200 elderly (men 545, women 655) over 65 years was obtained from the Korea National Health and Nutrition Examination Survey 2010. The subjects were divided into metabolic syndrome (MetS) and normal groups based on NCEP-ATP III guidelines and by applying the Asia-Pacific definition with waist circumference. The prevalence of MetS was 48.9% in all subjects, 35.6% in men and 58.9% in women, respectively. All nutrient intake was significantly lower in MetS than normal subjects, except iron, vitamin A, carotene, and retinol. In the carbohydrate: protein: fat (C:P:F) ratio, MetS showed a higher rate for carbohydrate, but a lower rate for protein and fat than normal. MetS was lower in calcium, vitamin B1, and vitamin C by the nutrient adequacy ratio than normal. Mean adequacy ratio of MetS (0.69) was lower than that of the normal group (0.72). These results demonstrated that undernutrition, not excess intake of specific nutrients - energy, fat, or cholesterol was associated with the risk for MetS in Korean elderly with MetS. Therefore, it is recommended to have a healthy dietary pattern with diverse nutrients for the prevention of MetS.

The purpose of this study was to estimate the nutrient intake, dietary habits, and body indices among preschool children. The study subjects were 166 kindergarten children, aged 4 to 6 years. A measurement of the weight, height, chest circumference, and head circumference of the children was conducted. The general home environment and factors related to the eating habits of children were collected using a questionnaire that included information about physical activity, outdoor playing time, television watching, family income, and parents education and occupations. Underweight, overweight were defined based on a value of less than 110 and more than 140 on the Rohrer Index, or less than 90 and more than 120 on the weight-length index (WLI). The average Rohrer and WLI for the preschool children were 14.3 $\pm$ 23.2% and 104 $\pm$ 13.5%. Using the WLI, 12.7% of the preschool children were underweight 62.6% were normal, and 24.7% were overweight or obese. On the Rohrer Index, 32.0% of the preschool children were underweight, 34.7% were normal, and 34.1% were overweight or obese. With regard to frequency of regularity of eating breakfast, 2.5% of preschool children skipped breakfast every morning. The risk of being overweight increased in preschool children who had faster eating times. The Rohrer and WLI were negatively related to faster eating times. The average daily energy intake was 1272 Kcal, which corresponded to 79.5% of the Korean RDA. In particular, the average intakes of calcium, iron, and vitamin B$_2$ were much lower than the Korean RDAs for each of those nutrients. Children whose mothers had occupations were at greater risk of decreased nutrient intake than those whose mothers were at home. The data presented in this study confirm that, in preschool children, undernutrition remains the nutritional problem of great concern in Korea, even though Koreans are starting to have worrisome rates of overweight. Therefore, during the early years of life, focus should remain on sustaining Proper growth and development.

Purpose of this study was to compare nutrient intakes of disabled children and non-disabled children. Subjects consisted of 86 disabled children from a special education school and 127 non-disabled children from an elementary school in Seoul. Nutrient intakes were assessed by modified 24-hr recall method, with the help of children's parents and teachers. Almost all nutrient intakes (energy, protein, fat, carbohydrates, vitamin B$_1$ and niacin) of children with cerebral palsy were significantly lower than those of other groups. But nutrient intakes per body weight of children with cerebral palsy were not significantly different with those of other groups. There was no significant difference between disabled and non-disabled children in almost % RDA (rate of actual intake to RDA) except of energy %RDA in children with cerebral palsy. NARs (nutrient adequacy ratio) for energy and vitamin B$_1$ of children with cerebral palsy were significantly lower than those of children with autism and mental retardation, and non-disabled children. The proportions of energy, carbohydrate and protein intakes from lunch were significantly higher than those from breakfast and dinner in children with mental retardation and autism. The nutrient intakes of disabled children were different between other groups according to the type of handicap. For example, children with cerebral palsy had the risk of undernutrition. On the other hand, autistic children had the tendency of overnutrition. These results suggest that nutrition educational programs and educational materials for disabled children, their teachers and their parents should be developed considering the type of handicap.

This study was conducted to evaluate nutritional status of school children by biochemical assessment method. Subjects were 308 school children from 4th to 6th grade living in Bucheon city. Their blood glucose, total protein, albumin, total cholesterol, and triglyceride (TG) concentrations were determined. Mean blood glucose concentration was 77.56 mg/dl and $81.2\%$ of children had normal blood glucose concentration. The average proportion of hypoglycemia was $18.8\%$ among the three grades and prevalence of hypoglycemia in 4th grade school children was highest ($21.8\%$). Mean serum total protein and albumin levels were 7.14g/dl and 4.35g/dl, respectively, and all the subjects except only one were in normal range of total protein and albumin. Mean serum TG and total cholesterol concentrations were 145.82mg/dl and 94.50mg/dl. Serum TG and total cholesterol levels showed same pattern that the concentrations decreased in proportion to grade. Especially, there was significant difference between grades in serum total cholesterol. Furthermore, $11.7\%$ of 4th, $6.8\%$ of 5th, and $2.8\%$ of 6th grade school children have borderline hypertriglycemia or hypertriglycemia, risk factors of obesity or cardiovascular disease later in life. Taken together, there was conflict phenomenon that undernutrition of hypertriglycemia and overnutrition of hypertriglycemia existed together. Therefore, it is needed to develop discriminating and personalized nutritional feeding, counseling, and education program to cover the children of under- or over- nutritional status.

Objectives: This study was undertaken to evaluate the intake of vitamins and minerals from dietary supplements (DSs) in Korean adults and elderly. Methods: Data for this study was generated from the 2017 Korea National Health and Nutrition Examination Survey (KNHANES). We analyzed 4,204 individuals aged 19 years and older (2,579 users and 1,625 non-users). The survey included 24-h recall questions on food and DS intakes, as well as questions on DS use over the past year. The nutrient DSs evaluated were calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C. Total nutrient intakes were obtained by combining nutrient intakes of foods and DSs consumed by each subject. Results: Most micronutrient intakes from food (except for thiamin) in adult users, and the four micronutrient intakes (iron, vitamin A, vitamin B₂ and vitamin C) in elderly users, were significantly higher than values obtained in non-users. For total intake of nutrients and DSs, both adult and elderly users had a significantly higher intake than non-users. While proportions below Estimated Average Requirements for all micronutrients by adding respective DSs in users were significantly reduced in adults and elderly as compared to non-users, the proportions of above Tolerable Upper Intake Levels for calcium and vitamin A in adults, and vitamin A in elderly, were significantly increased. In the total subjects examined, consumption of DSs was associated with lower odds ratios of undernutrition of micronutrients, and with higher odds ratios of overnutrition of calcium, iron, and vitamin A, as compared to non-users of DSs. Conclusions: Although DSs consumption by adults and the elderly improves the micronutrient status, it also increases the risk of excessive intake of certain vitamins and minerals.

Objectives: With an increase in the population of the elderly in Korea, their nutritional status has become a cause for concern. This study was designed to compare the nutritional intake and health status of the Korean elderly according to their body mass index. Methods: The subjects were 3,274 elderly people aged 65 and above who had participated in the 2016-2018 Korea National Health and Nutrition Examination Survey. The subjects were divided into four groups: underweight, normal, overweight, and obese, based on their BMI. The general characteristics, daily energy, and nutrient intakes, nutrient intakes compared to the recommended nutrient intake, percentage of participants whose nutrient intake was lower than the estimated average requirement (EAR), index of nutrient quality, the mean adequacy ratio (MAR), intakes by food group, and health status of the four groups were compared. Results: Underweight elderly people showed lower energy, lipids, dietary fiber, vitamin C, riboflavin, niacin, phosphorus, sodium, and potassium intake and MAR score (P < 0.001) compared to the normal or obese elderly. The mean protein, riboflavin, niacin, vitamin C, phosphorus, and iron intake of the underweight elderly was lower than the EAR (P < 0.05). Underweight elderly people also had a lower intake of vegetables and fats, oil and sweets food groups than the other groups (P < 0.001). The prevalence of diabetes and dyslipidemia was higher in the obese group, but the percentage of anemia was higher in the underweight group. Conclusions: Underweight elderly people were vulnerable to undernutrition and were at a higher risk of anemia.

Undernutrition could be a significant deterrent to healthy aging and could negatively affect health outcomes in elderly. This study aimed to assess health-related factors which are associated with nutritional risks in middle-aged and elderly individuals by a cross-sectional study. Interviews were conducted with 2660 subjects (847 males, 1813 females), aged 50 years and over, in 15 cities in Korea. Data on food intake were obtained through a validated semi-quantitative food frequency questionnaires. Nutritional status were analyzed according to health-related factors including cigarette smoking, alcohol drinking, exercise, stress and depression level. Less regular exercise was associated with a higher likelihood of a poor nutrition [odds ratio (OR) 1.94; 95% confidence intervals (CI) 1.43-2.65] of middle-aged and elderly male subjects. Cigarette smoking (OR 1.84; 95% CI 1.24-2.71), less exercise (OR 2.58; 95% CI 2.07-3.21), stress (OR 1.73; 95% CI 1.36-2.22), and depression (OR 1.34, 95% CI 1.08-1.67) of middle-aged and elderly female subjects was associated with a higher likelihood of a poor nutrition. The results of the multiple regression analysis showed that less exercise proved to be the strongest predictors for the poor nutrition, followed by stress, smoking, and depression (model $R^2= 9.0%$). It suggests that guidance to promote regular exercise, to quit smoking, to minimize stress and depression level might help to improve nutritional status of middle-aged and elderly in Korea. These findings also suggest that having recommendable health behaviors are beneficial to the good nutrition of subjects aged 50 years and over.

The aim of this cross sectional study was to examine the prevalence of sarcopenia in association with ADL, nutritional status and depression among community dwelling elderly women. The study subjects were 90 elderly women, 65 years and over, who were living in the communities of B and D metropolitan cities from May to July, 2014. The measurements were anthropometric measures, The mini-nutritional assessment instrument (MNA), ADL, IADL, MMSE, and SGDS-K were used. The mean age of the subjects was 74.7(8.22), the prevalence of sarcopenia of this population was 37.8%, almost none of them (94.4%) required assistance in ADL, 15.6% had a risk of undernutrition, and 12.2% had the symptom of depression. The sarcopenic subjects were characterized as low income, low education, living alone, and had more co-morbidity than those of the non-sarcopenic subjects. The sarcopenic subjects were undernourished, and had higher depression scores (SGDS-K), but not in the ADL, than those of the non-sarcopenic subjects. The calf and thigh circumferences, and cognitive ability were the best predictors of sarcopenia, In conclusion, low calf and thigh circumferences and low cognitive ability will increase the risk of sarcopenia in those 65 and over in community dwelling facilities and those three predictors will be useful in the early detection of sarcopenia in the future.

This research was peformed to investigate the anthropometric data, blood profiles, and nutrient intakes of elderly persons living in a rural area. The subjects were 67 undernourished people who participated in follow-up nutrition intervention programs for9 weeks. Anthropometric data showed that the mean heights and weights in the management group were 157.6 cm and 59.1 kg, respectively, for the males and 152.6 cm and 51.0 kg, respectively, for the females. The mean BMIs of the management group were 23.8 kg/m$^2$ in the males and 22.4 kg/m$^2$ in the females. The total cholesterol, HDL-cholesterol, and albumin levels of the subjects were 181.7-191.4mg/dL, 48.3-53.0mg/dL, and 3.85-4.00g/dL, respectively. Energy, ash, P, Na, vitamin B$_1$, vitamin B$_2$, vitamin B$_6$, and niacin increased significantly after intervention for the management group. The mINQ, however, did not significantly increase after intervention. Also after intervention, there was no significant difference in mINQ between the management group and the comparison group. MAR (14) in the management group was significantly increased from 0.62${\pm}$0.2 before intervention to 0.68${\pm}$0.2 after intervention (p=0.022), and it was significantly different between the management group and the comparison group (p=0.017). MAR (8) in the management group was not significantly different (p=0.915) before and after intervention. However, MAR (8) between the management group and the comparison group did show a significant difference (p=0.031). MAR (3) in the management group was significantly increased from 0.48${\pm}$0.2 before intervention to 0.55${\pm}$0.2 after intervention (p=0.045), however, MAR (3) was not significantly different between the management group and the comparison group (p=0.093). For the probability of nutrient insufficiency, in the management group the probability of nutrient values below the EAR (except for Fe) decreased after intervention compared to before intervention. On the other hand, the probabilities of values above the RI, or EAR${\sim}$RI, were increased
