BACKGROUND: Dietary patterns have a significant impact on prognosis, recurrence, and survival in patients with cancer. This study investigated dietary patterns using the Diet Quality Index-International (DQI-I) in cancer survivors compared to those in the general population without cancer.METHODS: Using the Korea National Health and Nutrition Examination Survey VI data, cancer survivors were defined as those diagnosed with cancer more than 1 year before the survey. The associations between possible predictors and the DQI-I score were examined using t-tests and analysis of variance. Adjusted multiple linear regression analysis was performed to compare the differences in DQI-I scores between cancer survivors and controls.RESULTS: In univariate analysis of 9,351 subjects (433 cancer survivors and 8,918 controls), age, sex, body mass index, marital status, education level, income, residential area, smoking status, and alcohol consumption were associated with the DQI-I score (each P-value < 0.05). After adjustment, cancer survivors showed higher DQI-I scores than the controls (67.40±8.90 vs. 65.50±9.40, P-value=0.007). In subgroup analysis, cancer survivors within 5 years after cancer diagnosis showed higher DQI-I scores than the controls (68.70±8.30 vs. 65.50±9.40, P-value=0.034), whereas those who survived beyond 5 years post-diagnosis did not show significant differences from the controls (66.70±9.20 vs. 65.50±9.40, P-value=0.063).CONCLUSION: Cancer survivors within 5 years of cancer diagnosis showed better dietary patterns than those in the general population. However, the differences were not observed after 5 years post-diagnosis. To reduce the risks of second primary cancer and mortality, targeted inventions for dietary habits are necessary for long-term survivors of cancer.

PURPOSE: This study evaluated the glycemic response of diets using estimated glycemic load (eGL), which had been developed for mixed meals for Korean adults, and examined its associations with cardiometabolic risk factors among Korean adults. METHODS: A total of 4,655 men and 6,760 women aged 19 years and above were included from the 2013 ~ 2016 Korea National Health and Nutrition Examination Survey. eGL was calculated by each meal (breakfast, lunch, dinner, and snack) and then summed to give daily total eGL. A multiple logistic regression analysis was used to examine the association. RESULTS: Mean daily total eGL was 112.6 in men and 99.3 in women. Daily total eGL was positively associated with carbohydrate and fiber intakes, but negatively associated with protein and fat intakes in both men and women (p < 0.05 for all). Daily total eGL showed an inverse association with HDL-cholesterol level in both men and women (p = 0.0036 for men and p = 0.0008 for women). Men in the highest quintile of daily total eGL showed a 66% increased risk of hypercholesterolemia (OR, 1.66; 95% CI, 1.10 ~ 2.50; p for trend = 0.0447) compared with those in the lowest quintile. CONCLUSION: These findings suggest that eGL based on carbohydrate, protein, fat and fiber intakes can reflect glycemic response and therefore can be used as an index for dietary planning, nutrition education and in the food industry.

PURPOSE: North Koreans could be at higher risk for their bone health because of previous periods of severe famine and the continuing low availability of food. This study determined the bone mineral density (BMD) status and its relationship with dietary behaviors and nutrient intake of North Korean refugees (NKR) in South Korea (SK). METHODS: This cross-sectional study analyzed 110 female NKR from a NORNS cohort of a non-probability sample of adult NKR in Seoul. BMD examined by DEXA was used to divide participants into the normal group (NG) and the non-normal group (NNG) according to the WHO guideline. A self-administered questionnaire included questions on age, the socioeconomic situation in North Korea (NK) and SK, the food security in NK and SK, and the health behaviors, dietary behaviors, and food frequency questionnaire administered in SK. A one-day 24-hr recall was conducted and the results were analyzed by using CanPro. SPSS was used to analyze whether BMD and related dietary behaviors and nutrient intakes differed according to the groups. RESULTS: NG (62.7%) was significantly younger and had a lower abdominal obesity score than NNG (p < 0.001). While 14.5% of NG reported experiencing menopause, all of NNG reported experiencing menopause. The NG more frequently consumed the dairy group of foods (9.6 times a week) than did the NNG (4.8 times a week) after the statistics were adjusted for age (p < 0.007). The NG consumed significantly more animal protein and animal calcium than did the NNG (p = 0.01, p = 0.009, respectively). Calcium intake was low with 49.3% of NG, and 78.0% of the NNG reported consuming calcium lower than the estimated average requirement. Only calcium showed an index of nutrient quality lower than one in both groups. CONCLUSION: These results showed that NKR women and possibly all North Korean women are at high risk for bone health and they consumed low levels of bone-related nutrients, and this should be considered for the nutrition policy for NKR and North Korea.

OBJECTIVES: This study was undertaken to compare dietary life of the elderly living alone and in a family, and to compare differences based on gender, for the 2013-2016 Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: The subjects included 2,612 elderly people aged over 65 years who participated in the health survey, health examination and nutrition survey. Subjects on a diet therapy were excluded. This study analyzed the general characteristics, dietary habits, daily energy and nutrient intakes, CPF ratio, estimated average requirement (EAR), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR), index of nutrient quality (INQ), and food consumption of the elderly living alone and in a family. We also compared the differences based on gender. RESULTS: Daily intake of food, water, dietary fiber, potassium, retinol, and riboflavin were low in the male elderly subjects living alone. The elderly living with family revealed higher NAR and MAR as compared to the elderly living alone. Although all MAR values were <1, the elderly living alone had lower values. Considering the intake of food, the consumption of seaweed, fish and shellfish, and oils (animal) was higher in elderly men living with families, whereas women living with families consumed more vegetables, fruits, seaweeds and seafood, as compared to their counterparts living alone. Furthermore, analyzing the foods consumed by the elderly people living alone, female subjects consumed more seaweed, milk and animal oil as compared to male subjects. CONCLUSIONS: The results of this study indicate that the elderly living alone have poor nutrient intake as compared to the elderly living with families. Based on this research data, we recommend that it is necessary to improve the health and nutritional status of the elderly living alone.

BACKGROUND: Ventilator dependency constitutes a major problem in the intensive care setting. Malnutrition is considered a major determinant of extubation failure, however, attention has been attracted to modulating carbon dioxide production through decreasing carbohydrate loading and increasing the percent of fat in enteral feeds. The detected interrelation between substrate oxidation and ventilation outcome became the base of several research to determine the appropriate composition of the nonprotein calories of diet in ventilated patients. PURPOSE: We aimed to assess the effect of high-fat dietary modification and nutritional status on ventilatory and final outcomes of pediatric intensive care. METHODS: Fifty-one ventilated children (1 month to 12 years of age) with pulmonary disease who could be enterally fed, in the Cairo University Pediatric intensive care unit, were divided into 2 groups: group A included 25 patients who received isocaloric high-fat, low-carbohydrate diet; group B included 26 patients who received standard isocaloric diet. Comprehensive nutritional assessment was done for all patients. RESULTS: Group A had a significant reduction in carbon dioxide tension, but no similar reduction in the duration or level of ventilatory support. Assisted minute ventilation was predicted by weight-for-age and caloric intake rather than the type of diet. Poor nutritional status was associated with higher mortality and lower extubation rates. Mild hypertriglyceridemia and some gastrointestinal intolerance were significant in group A, with no impact on the adequacy of energy or protein delivery. CONCLUSION: The high-fat enteral feeding protocol may contribute to reducing carbon dioxide tension, with mild hypertriglyceridemia and negligible gastrointestinal intolerance as potential adverse effects. Optimization of nutritional status rather than dietary modification may improve ventilatory and survival outcomes in critically ill-ventilated children.

BACKGROUND: The health condition of old age is affected by various factors such as economic level, disease condition, and nutrition. With the aging population in Korea, the ratio of single-person households increased rapidly. Research on the health status and nutrition of the elderly in the single-person household is very insufficient. In this study, we compared the health and nutritional status of the elderly by the household type. METHODS: Data from the 2013 to 2014 Korea National Health and Nutrition Examination Survey were used. A total of 2,730 patients were classified into 2 groups (single-person, with family), and general, chronic disease, health behavior, nutrient intake, and food insecurity status were compared by the statistical analysis. RESULTS: Single-person households had a low economic and educational level and a higher percentage of women. In addition, obesity, hypertension, dyslipidemia, stroke, myocardial infarction disease rate was significantly higher. Sing-person households answered that their subjective health status was bad, and their quality of life was low. As a result of analysis of the quality of the diet in the single-person, the intake of protein, calcium, iron, vitamin B2, niacin, and vitamin C was significantly lower. In particular, the intake of calcium was the most insufficient. Food insecurity has also been observed, including the inability to consume diverse and sufficient foods due to economic difficulties. CONCLUSIONS: More attention should be paid to the health of single-person households in elderly population and various policies should be prepared.

PURPOSE: This study examined dietary and health characteristics of the young-old and the old-old by food security status. METHODS: The study used data from the 6th (2013 ~ 2015) Korea National Health and Nutrition Examination Survey. The study subjects consisted of 3,948 subjects, of whom 2,445 were the young-old (aged 65 to 74 years) and 1,503 were the old-old (aged 75 years and over). Food security status was evaluated using an 18-item questionnaire. Energy intake, nutrient densities, and prevalence of insufficient nutrient intake were assessed. Food intake was evaluated in terms of the number of food group servings. Dietary behaviors and health status were also assessed. RESULTS: The prevalence of food insecurity among the young-old and the old-old was 10.0% and 11.6%, respectively. Among the young-old, the food insecure group had a significantly higher level of prevalence of insufficient intake for all the nutrients (protein, vitamin A, thiamin, riboflavin, niacin, vitamin C, calcium, phosphorous, and iron) assessed in this study compared with the food secure group. In case of the old-old, significant differences were found only for four nutrients (protein, riboflavin, niacin, and phosphorus) in the prevalence of insufficient nutrient intake between the food secure and the food insecure groups. Kinds of food groups with significantly different numbers of servings by food security status were dissimilar between the two age groups. In both the age groups, the food insecure group consumed a significantly lower number of servings in meat·fish·eggs·legumes and fruits than the food secure group; grains and vegetables intake in the young-old and oils·sweets intake in the old-old differed in the number of servings by food security status. Among the young-old, the prevalence of chewing difficulties in the food insecure group was significantly higher than that of the food secure group, while among the old-old, no significant differences were found by food security status. CONCLUSION: Dietary and health characteristics of the young-old and the old-old differed by food security status. Such differences were more apparent in the young-old than the old-old. Therefore, it is suggested that food and nutrition assistant programs should be designed with consideration of the differences.

BACKGROUND: This study aimed to investigate the dietary habit problems related to sleep duration by analyzing health behaviors and dietary habits in Korean adults.METHODS: Adults aged ≥19 years who participated in the 2013-2015 Korea National Health and Nutrition Examination Survey were included in the study. Subjects were classified into the insufficient, appropriate, and excessive sleep groups. Subsequently, patient characteristics, health status, obesity and metabolic syndrome, dietary habits, and nutrient intake were analyzed.RESULTS: The subjective health status was worse in the insufficient and excessive sleep groups than that in the appropriate sleep group. Body mass index and obesity and abdominal obesity rates were higher in the insufficient and excessive sleep groups than in the appropriate sleep group. The insufficient and excessive sleep groups had an irregular diet, and the excessive sleep group had significantly lower vitamin and mineral intake than insufficient and excessive sleep groups.CONCLUSIONS: Subjects in the insufficient and excessive sleep groups were less healthier than those in the appropriate sleep group. Further, subjects in the excessive sleep group had an unbalanced diet and nutritional status.
