Purpose: Food intake of COPD patients decreases because of appetite loss, depression, and breathing problems while eating, which increase the likelihood of patients becoming malnourished. This study investigated the nutrient intake and dietary quality of people with and without COPD in Korea. Methods: There were 2,160 adults aged 50 and over who participated in the $5{\sim}6^{th}$ Korea National Health and Nutrition Examination Survey. The subjects were divided into the COPD group and non-COPD group according to the rate of forced expiratory volume at 1 second (FEV1) against forced vital capacity (FVC). Consumption of food and nutrients were calculated based on the nutrition examination survey. Statistical analyses were conducted using SPSS 19.0. Results: Among individuals in their 50s, intake of vitamin $B_1$ in the COPD group was significantly less than the NCOPD group, while intake of sodium in the COPD group was significantly greater than the NCOPD group. Among individuals in their 60s, the energy intake of the COPD group was significantly less than that of the NCOPD group. The COPD group showed significantly less intake of vitamin $B_1$ and vitamin C, but greater intake of sodium than the NCOPD group. In the group aged 70 and over, The COPD group had significantly less intake of vitamin $B_1$ than the NCOPD group and showed lower nutrient adequacy ratio values in protein, vitamin $B_1$, vitamin $B_2$, and iron than the NCOPD group. Conclusion: The COPD group consumed less energy and certain nutrients, and their dietary quality was poor compared to the NCOPD group. Thus, more detailed research is required to understand the concrete relationship between COPD and malnutrition.

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.

Purpose: Previous studies have reported the difference in nutritional status between South and North Korean infants and young children (IYC). Clear understanding on the nature of such differences is essential for planning food and nutrition policies and programs to prepare for a possible re-unification of the two Koreas in future. This study was undertaken to yield valid statistics comparing the nutritional status between North and South Korean IYC. Methods: Raw data obtained from the 2017 Korean National Growth Chart and the 2013-2017 Korea National Health and Nutrition Examination Survey were analyzed to determine the comparable statistics that include weight for age z-score (WAZ), height for age z-score (HAZ) and weight for height z-score (WHZ), with data reported in the Survey Findings Report of the 2017 DRP Korea Multiple Indicator Cluster Survey. The average weight and height by gender and month were estimated for North Korean IYC and calculated for South Korean IYC. SPSS analysis was applied to evaluate the acquired statistics and compare the nutritional status of South and North Korean IYC. Results: WAZ, HAZ and WHZ of North Korean IYC were observed to be lower than values obtained for South Korean IYC as well as the median values of World Health Organization Child Growth Standards across all ages. Similar patterns were observed for average height and weight. The nutritional status of North Korean IYC revealed a prevalence of highly underweight (9.3%), stunting (19.1%) and wasting (2.5%) values, and was determined to be significantly lower than values obtained for South Korean IYC (0.8%, 1.8%, and 0.7%, respectively). Conclusion: This study has yielded valid statistics that compare the nutritional status of North and South Korean IYC. Results of this study confirm the prevalence of nutritional status difference between South and North Korea.

The objective of this study is to select a simple and easy measurable food behavior checklist for the development of Nutrition Quotient (NQ) for children, which reflects children's diet quality, as well as to evaluate the validity of the items in the food behavior checklist. The first 36 items in the checklist were established by an expert review, modifying the preliminary 50 items in the checklist, which had been selected by a literature review and the Korean National Health and Nutrition Examination Survey data. 341 children in 5th and 6th grades at an elementary school participated in a one-day dietary record survey, and later responded to 36 food behavior questions of the checklist. Pearson's correlation coefficients between the responses to the food behavior checklist items along with the mean nutrient intakes of the children were calculated. From the result, in which responses of food frequency and food behavior items showed certain association with the dietary record data, a second checklist with 22 items was selected. A survey was conducted by using the second checklist. 1,393 children in the 5th and 6th grades at 12 elementary schools in metropolitan cities, such as Seoul, Busan, Gwangju, Daegu, Daejeon, and Incheon, participated in the survey. Further, an exploratory factor analysis was performed. After the analysis, 19 items (10 items from food frequency and 9 items from food behavior) were finalized as the food behavior checklist items for the NQ. The final 19 food behavior checklist items were composed of 5 factors: 'Balance', 'Diversity', 'Moderation', 'Regularity', and 'Practice'. This study is a significant first trial to establish a comprehensive system for evaluating children's food habit and diet quality. This checklist might need continuous modification and revision reflecting the change of children's dietary life and the social environment.
