In this study we compared the cognitive function (Mini-Mental State Examination for Dementia Screening: MMSE-DS) and nutrient intake of elderly women with dementia in a long-term care facility (EW-LCF) and a day-time care facility (EW-DCF). This survey was conducted from July 2015 to May 2017 on 73 elderly women with dementia (47 women in LCF and 26 women in DCF) in the city of Incheon. The data obtained from interviews with the subjects and caregivers were analyzed using the SPSS 20.0. The total score of the MMSE-DS and intakes of most nutrients in the EW-LCF were significantly lower compared to the EW-DCF (p<0.05). The nutrient adequacy ratios (NAR) of protein, vitamin A, C, $B_6$, $B_{12}$, thiamin, riboflavin, niacin, folic acid, calcium and phosphorus in the EW-LCF were significantly lower compared to the EW-DCF (p<0.05). However, the indexes of nutritional quality (INQ) of vitamin C, $B_6$, thiamine, niacin, calcium, magnesium, and iron in the EW-LCF were significantly higher compared to the EW-DCF (p<0.05). As a result, the subjects showed an unbalanced and insufficient nutrition intake status regardless of the type of care facility. Most nutrient intakes of the EW-LCF with lower cognitive function were very significantly lower compared to the EW-DCF (p<0.001). Therefore, it is necessary to assess the cognitive function and nutritional status regularly at care facilities for the elderly women suffering with dementia and to provide specialized individual nutritional management.

Objectives: The purpose of this study was to investigate the blood biochemical characteristics, comorbidities, dietary intake, and other risk factors leading to poor glycated hemoglobin (HbA1c) control in elderly Korean diabetes patients over 65 years of age. Methods: Data from the 4^th (2007-2009) and the 7^th (2016-2018) Korea National Health and Nutrition Examination Surveys (KNHANES) were used. Socio-demographic characteristics (age, gender, region, household income, education level, marital status, nutrition education, diabetes duration and diabetes treatment), lifestyle characteristics (drinking, smoking, regular walking, and subjective health perception), anthropometric characteristics (height, weight, and waist circumference), blood biochemical characteristics (HbA1c, high- density lipoprotein cholesterol, triglycerides, total cholesterol, blood urea nitrogen, and blood creatinine), co-morbidities (obesity, hypertension, hypercholesterolemia, hypertriglyceridemia, and anemia), energy and nutrients intake, food group intake, and HbA1c control-related risk factors were compared. Results: Compared to the 4^th survey, the 7^th survey showed an increase in diabetes prevalence among men, an increase in the prevalence of diabetes in the older patients, and an increase in the duration of diabetes. The energy ratio from carbohydrate consumption in the 7^th survey was lower than in the 4^th. Compared to the 4^th survey, thiamine and riboflavin intake had improved, and the intakes of vitamin A, vitamin C, and niacin had worsened in the 7^th. A comparison of food group intakes showed that there was a decrease in the consumption of whole grains, potatoes, and milk and an increase in the intake of beverages and alcoholic beverages. The risk factors for poor control of HbA1c were the duration of diabetes and co-morbid hypertriglyceridemia in the 4^th survey, whereas subjective health perception, obesity, and hypercholesterolemia as co-morbidities were found to be risk factors in the 7^th in addition to the risk factors highlighted in the 4^th survey. Conclusions: For the future management of elderly Korean diabetes patients, greater care is indicated for men over 75 years, and those with low levels of education. It is necessary to increase the intake of milk and vegetables, and reduce the intake of beverages and alcoholic beverages. In addition, it is necessary to reduce the incidence of obesity, hypercholesterolemia, and hypertriglyceridemia for proper control of blood sugar.

Objectives: The purpose of this study was to examine the biochemical characteristics, intake of energy, and nutrients by household income levels of Korean adolescents aged 12 to 18 years. Methods: Data from the 6th (2013 ~ 2015) Korea National Health and Nutrition Examination Survey (KNHNES) were used for the study. A total of 1,839 (966 boys, 873 girls) subjects were included, and they were divided into four income groups according to their household income level. We examined general characteristics (gender, region of residence, skipping or not-skipping breakfast, lunch, dinner, frequency of eating-out), anthropometric characteristics (height, weight, weight status), biochemical characteristics (fasting plasma glucose, blood urea nitrogen, creatinine, triglycerides, cholesterol, HDL-cholesterol, hemoglobin, and hematocrit), the quantitative intake of energy and nutrients using the Korean Dietary Reference Intakes (KDRI), and the qualitative intake evaluated by the nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) of the four groups. Results: There were significant differences by income group within the region of residence and the rate of skipping breakfast, lunch, and dinner. The low-income group had a higher rate of skipping breakfast, lunch, and dinner. According to the income group, there was a difference in the height of boys, and there was no difference in the weight and obesity of boys and girls. In the biochemical characteristics, only the hematocrit of girls showed differences by income group. The quantitative intake of energy and nutrients compared with KDRI differed by income group. There were differences in energy, carbohydrates, proteins, thiamin, riboflavin, niacin, and phosphorus levels in boys and protein, vitamin A, niacin, and sodium levels in girls. The qualitative intake of energy and nutrients examined using NAR and MAR also differed according to the income group. The NAR showed differences in calcium in boys and vitamin C and calcium in girls. The MAR revealed differences in both boys and girls by income group. Conclusions: Among adolescents in the low-income group, the rate of skipping meals was high, and the quantitative and qualitative intake of energy and some nutrients was low. It is suggested that the nutritional intake can be improved by lowering the rate of skipping breakfast, lunch, dinner. We suggest that even just providing breakfast in schools can be considered highly effective in improving the rate of avoidance of skipping meals and improving nutrient intake. Also, we suggest that it is necessary to improve the food environment, food availability, and food accessibility through national and social support for low-household income adolescents.
