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.

The purpose of this study was to evaluate the nutritional status of elderly women living in residential homes by estimating nutrients and food intakes. Food consumption survey was conducted by 3-day 24hr recall method with 99 elderly women aged 65 to 90 years from three residential homes in Seoul, Choonchun and Chunan and 46 free-living elderly women aged 65 to 88 years from Chunan as control group. Food intake data was converted into nutrient intake using computer aided nutritional analysis program. Mean energy intake and percentage of recommended daily allowance (RDA) of residential home residents were 1696㎉ and 101% of RDA while those of control were estimated as 1939㎉ and 119% of RDA. On average, absolute amount of nutrient intakes of residential home residents were slightly higher than control group. Subjects in control group showed significantly lower carbohydrate and vitamin A intake, while vitamin C intake was higher. However, nutrient intake quality determined by INQ (Index of nutritional quality) was significantly higher among control subjects in most nutrients except vitamin A than residential home residents. Intakes of calcium, vitamin A and riboflavin of all subjects in this study were less than 75% RDA meaning that nutritional status of calcium, vitamin A and riboflavin was insufficient and could possibly result in nutritional deficient. Some food groups such as milk or other dairy products must be strongly suggested to improve nutritional status of elderly women in this study. According to the results of this study, meal plans of residential homes are quite adequate in quantity of micronutrients, but need to be improved in both quantity and quality of micronutrients.

The relationship of abdominal obesity ("AO") with co-morbidity and mortality is well established. This study assessed the factors associated with AO, which was defined as a waist circumference ≥90 cm for men and ≥85 cm for women, in the group aged over 65 years. A total of 1,435 subjects were analyzed among the participants of the 2014 Korean National Health and Nutrition Examination Survey. Statistical methods for a complex sample were applied by using a SPSS program (ver. 25.0). AO was more frequently found in females. The results of the logistic regression analysis showed that heavy drinking (OR: 1.53), no weight training (OR: 0.68), stressful mental status (OR: 0.61), bad health-related quality of life (by EQ_5D, OR: 1.45), hypertension (OR: 2.18), prediabetes (OR: 1.94), diabetes (OR: 1.63), low HDL-cholesterol (OR: 1.86), anemia (OR: 0.55), and heavy energy intake (OR: 1.41) were significantly related with the prevalence of AO after adjustment for gender. Heavy drinking (OR: 1.89), bad self-rating of health status (OR: 1.72), low HDL-cholesterol (OR: 1.85), heavy energy intake (OR: 1.79), low intake of riboflavin (OR: 1.60) were still significantly related with the prevalence of AO after adjustment for gender and body mass index (BMI), this study suggests that certain characteristics of health habits, mental health status, and chronic diseases may be associated with AO. This study did not establish the existence of relationship between nutrient intakes, except for riboflavin, and risk of AO, but this study suggests that prospective research is needed to establish causal connections among those factors.

Nutrients intake status of 73 lactating women, that is 45 breast feeding (BF), 13 formula feeding (FF) and 15 mixed feeding (MF), living in Daejeon was investigated. Self-recorded food intakes for two weekdays and eating behaviors using questionnaires were surveyed from May to August 2008. Subjects aged $29.2{\pm}3.4$ years and their infants aged $8.2{\pm}3.2$ months. Body mass index of the subjects was $21.0{\pm}3.2$. Of the subjects 23.3% were employed. Daily energy intake was $1953{\pm}391$ kcal. Mean adequacy ratio (MAR) was $0.77{\pm}0.14$ and was higher in FF ($0.86{\pm}0.13$) than in BF ($0.76{\pm}0.11$) and MF ($0.72{\pm}0.18$). Nutrients that over 50% of the subjects took less than estimated average requirement were vitamin A, riboflavin, folate, vitamin C and calcium. And index of nutritional qualities of those 5 nutrients were below one Forty six and sixths percent (46.6%) of the subjects showed GMFVD = 11111 pattern of five food group intakes and 57.5% took meals three times daily, 56.2% skipped often breakfast, and 64.4% dined out two times and more per week. Subjects having lower MAR (< 0.72, n = 24), compared with those having higher MAR (${\geq}$ 0.83, n = 24), showed more skipping daily meals and less frequency of eating-out, and took less legumes, vegetables, fishes, and milk. As the results, intakes of calcium, vitamin A, riboflavin, folate, and vitamin C were insufficient in lactating women, especially in BF and MF mothers. Meal skipping and low intakes of dairy foods, legumes, vegetables, and fishes might have adverse influences on nutritional status of lactating women. Accordingly, nutrition care program for lactating women should be focused on intake of three meals daily and a variety of food.

This study was conducted to examine the status of food consumption and nutrition intake of young adults according to food security using data from the Korea National Health and Nutrition Examination Survey (KNHANES) (2008~2018). A total of 10,655 young adults aged 19~34 years participated in the study. The subjects in the moderately/severely food insecure group consumed less fruits, vegetables, meat, nuts and seeds than those in food secure/mildly food insecure group after adjusting for confounding factors. The moderately/severely food insecure group significantly decreased mean adequacy ratio (MAR) and nutrient adequacy ratio (NAR) for protein, vitamin A, riboflavin, niacin, vitamin C, calcium, phosphorus and iron compared to the food secure/ mildly food insecure group. The percentages of the participants consuming a daily diet with carbohydrate, protein, vitamin A, thiamin, riboflavin, niacin, vitamin C, phosphorus and iron less than the estimated average requirement (EAR) increased in the moderately/severely food insecure group compared with the food secure group. This study suggested that the nutrition intake of young adults was related to food security status. These findings can be used as basic data for developing nutritional policies for young adults.

Objectives: This study investigated the health and nutritional status of the elderly according to the number of chronic diseases, using data obtained from the Korea National Health and Nutrition Examination Survey 2013~2015. Methods: Data from a total of 2,310 individuals, aged 65 years and over, were used for the analysis. The elders were divided into 0 (n=375), 1 (n=673), 2 (n=637) and 3 or more (n=625) groups, by considering the number of chronic diseases. Results: Compared to other groups, the elderly subjects who were living with their spouse had the highest ratio in group 0 (P < 0.05), whereas subjects without economic activities had highest ratio in 3 or more group (P < 0.05). The EQ-5D index of subjects in the 0 group (0.90 ± 0.01) was higher than that in the 3 or more group (0.86 ± 0.01) (P < 0.05). After adjusting for confounding factors, the energy intake of subjects was determined to be lowest in the 3 or more group (P < 0.05). Protein (P < 0.05) and riboflavin (P < 0.05) intakes of the 3 or more group were also lower than other groups. Conclusions: This study indicates that multimorbidity of the elderly is associated with their health and nutritional status. The nutrients intake of the elderly, especially energy, protein and riboflavin, tended to be lowest in the 3 or more group. Further research is required to elucidate the risk factors related to presence of multimorbidity in the elderly.

To evaluate the effectiveness of nutritional supplements for cancer patients, the study was performed in 30 cncer patients, receiving chemotherapy. Patients were randomly divided into two groups -15 patients for the nutritionally supplemented group and 15 patients for the control group. Patients of the supplemented group were nutritionally supported with a commercial product for 9 weeks. Nutritional status of the patients was detrmined by dietary intake data, anthropometric measurements and hematological analysis at the beginning and after 3, 6 and 9 weeks of supplemental priod. Mean daily intake levels of energy, protein, calcium, phosphorus, thiamin, riboflavin, niacin and asorbic acid for the supplemented group were significantly higher than those of control group. Significant increase in mid-arm circumference, triceps skinfold thickness and arm fat area were observed in supplemented group during the study period. However, the changes of body weight, body mass index and arm muscle area were not significantly increased. Serum transferrin level improved slightly by nutritioal support, but serum albumin levle did not change significantly. There data show that nutritional status of cancer patients receiving chemotherapy can be improved by utritional supplementation for 9 weeks.

The purpose of this study was to investigate the nutritional status of school lunch supported students and to provide fundamental data for improving their health. In order to do that, we collected the data for 59 school lunch supported students and 71 not supported students in an elementary school in the Taegu Metropolitan city area. The survey was conducted from February 10 to April 30, 2000. The results are as follows; In relation to their body composition(BMI, Fatmass, Percent Body Fat, Mid-upper Arm Muscle Circumference, Mid-upper Arm Circumference), the school lunch supported students' value was lower than that of the not supported students. In relation to food intake according to the food groups, the school lunch supported students' intake of animal food(p<0.05) and total food(p<0.01)was significantly lower than that of the other students. The average intake of energy for both school lunch supported students and not supported students was below the RDA. Also, it was significantly lower than that of the school lunch supported students in relation to the other students(p<0.05). For protein, calcium, phosphorous, and riboflavin, the school lunch supported students' intake was significantly lower than that of the students who were not supported(p<0.05, p<0.05, p<0.05, p<0.05). There are the classification in relation to the nutrient intake in relation to the RDA standards for that of the school lunch supported students. The criteria used for this study was calorie intake, protein, and niacin. The classifications are for groups below 75%, between 75%～100%, and 100%. The nutrients for which the students were deficient( below 75%) of the RDA were iron, calcium, riboflavin, vitamin C, thiamin, calorie, niacin, vitamin A, protein, and phosphorous in the above order.

Menopausal status and hormonal changes are important factors related to the prevalence of metabolic syndrome in women. Nutrient intake is also a risk factor for metabolic syndrome. Although, postmenopausal status and hormonal changes result in a 60% increased risk for metabolic syndrome, there has been no method to elucidate the effects of nutrient intake on metabolic syndrome following menopause. This study was conducted to evaluate the effects of nutrient intake by menopausal women on the prevalence of metabolic syndrome. All data were obtained from the Korean National Health and Nutrition Examination Survey 2007-2009. Menopausal women showed a 1.8-fold increase in the prevalence of metabolic syndrome. Metabolic syndrome group showed significantly lower values in calcium, iron, vitamin A, carotin, retinol and riboflavin intake than those of normal group in premenopausal women. In postmenopausal women, there are significant differences in crude fiber, calcium, iron, potassium, riboflavin and niacin. Indeed, different patterns of nutrient intake were observed by menopausal status and metabolic syndrome. As menopause cannot be controlled, a diet with adequate nutrient intake may be useful to control the rapid increase in the prevalence of metabolic syndrome due to menopause.

This study was conducted to examine the nutritional status, quality of diet and quality of life in postmenopausal women with mild climacteric symptoms based on their food group intake patterns. The data for nutritional status were obtained using 3-day records. Quality of diet was assessed by INQ, NAR, MAR, DDS, DVS, DQI-I. Climacteric symptoms were analyzed by the questionnaire of Kupperman's index and MENoL. The subjects were classified into the five groups, GMVDF, GMVdF, GMVDf, GMVdf, GmVDF according to their food group intake patterns. Analysis of nutrient intakes showed that the GMVDF group took significantly higher levels of kcal, carbohydrate, protein, fat, vitamin A, thiamin, riboflavin, folate, vitamin C, vitamin E, calcium, phosphorous, sodium, iron, zinc and fiber than GMVdf group did (p < 0.05). INQ of Ca and Fe appeared to be higher in GMVDF than in GMVdf groups (p < 0.05). Analysis of NARs showed that missing milk groups took lower riboflavin, Ca and P than other groups did as the same result with MAR (p < 0.05). Analysis of DDS and DQI showed that GMVdf group had the lowest quality of diet (p < 0.05); however, no difference was found on DVS. The GMVdf group showed the worst climacteric symptoms compared with those of the other groups (p < 0.05). However, we couldn't observe any differences in menopause-specific quality of life among the groups. In conclusion, it would be beneficial to meet all five food groups to increase the quality of diet and to reduce the climacteric symptoms in postmenopausal women.
