This study was conducted to analyze relationships between depression indices, mini nutritional assessment scores, and nutritional quotients among 80 elderly in Yangpyeong-gun and to identify factors that help prevent depression and malnutrition. Nutrition assessment scores were low in the high-risk group (PHQ-9 score ≥10), and nutritional quotient scores were lower in the high-risk group than in the normal group (PHQ-9 score ≤4). Interestingly, the consumption frequencies of fruits, eggs, and nuts were low in the high-risk group, and subjective health awareness, dental condition, and sleep were poorer. The total PHQ-9 score was correlated with malnutrition, body mass index, calf circumference, weight change, independent daily living, reduced meal amount, water intake, and the need for help when eating. Analysis of correlations between items of the PHQ-9 and nutritional status evaluation indices showed that a self-perceived feeling of depression, low energy, difficulty controlling sleep or appetite, negative thoughts (e.g., failure, disappointment), and difficulty concentrating were negatively correlated with total nutritional status scores. These results show that attention is required when food or water intake decreases and that deviation from normal sleep and appetite cycles flags the need to prepare guidelines to prevent depression.

Both metabolic syndrome (MetS) and elevated LDL cholesterol (LDL-C) increase the risk for cardiovascular disease (CVD). We hypothesized that low HDL cholesterol (HDL-C) would further increase CVD risk in women having both conditions. To assess this, we recruited 89 women with MetS (25-72 y) and LDL-C ${\geq}$ 2.6 mmol/L. To determine whether plasma HDL-C concentrations were associated with dietary components, circulating atherogenic particles, and other risk factors for CVD, we divided the subjects into two groups: high HDL-C (H-HDL) (${\geq}$ 1.3 mmol/L, n=32) and low HDL-C (L-HDL) (< 1.3 mmol/L, n=57). Plasma lipids, insulin, adiponectin, apolipoproteins, oxidized LDL, Lipoprotein(a), and lipoprotein size and subfractions were measured, and 3-d dietary records were used to assess macronutrient intake. Women with L-HDL had higher sugar intake and glycemic load (P< 0.05), higher plasma insulin (P< 0.01), lower adiponectin (P< 0.05), and higher numbers of atherogenic lipoproteins such as large VLDL (P < 0.01) and small LDL (P<0.001) than the H-HDL group. Women with L-HDL also had larger VLDL and both smaller LDL and HDL particle diameters (P<0.001). HDL-C was positively correlated with LDL size (r=0.691, P<0.0001) and HDL size (r=0.606, P<0.001), and inversely correlated with VLDL size (r=-0.327, P<0.01). We concluded that L-HDL could be used as a marker for increased numbers of circulating atherogenic lipoproteins as well as increased insulin resistance in women who are already at risk for CVD.

The objectives of this study were to investigate the quality characteristics of nutritional cereal bars with various concentrations (0, 5, 10, 15, 20%) of Citrus fruit extract. Regarding the color of nutritional cereal bars, the L value decreased according to the amount of nutritional cereal bars added, whereas a, b color values increased. The nutritional cereal bar with 5, 10, 15, and 20% Citrus fruit extract had a significantly lower hardness value than the control nutritional cereal bar. The result of a sensory test showed that the scores for color, taste, texture, and overall acceptability were the highest for the nutritional cereal bar with 15% Citrus fruit extract. The nutritional cereal bar with 20% Citrus fruit extract attained the highest flavor score. The results indicated that optimal concentration of Citrus fruit extract in nutritional cereal bars were 15%. The quality characteristics of the nutritional cereal bar were also potential materials for good healthy food.

Objectives: This study examined the characteristics of patients according to nutritional status assessed by five nutritional screening tools: Patient-Generated Subjective Global Assessment (PG-SGA), NUTRISCORE, Nutritional Risk Index (NRI), Prognostic Nutritional Index (PNI), and Controlling Nutritional Status (CONUT) and to compare the agreement, sensitivity, and specificity of these tools. Methods: A total of 952 gastric cancer patients who underwent gastrectomy and chemotherapy from January 2009 to December 2012 were included. The patients were categorized into malnutrition and normal status according to five nutritional screening tools one month after surgery. The Spearman partial correlation, Cohen's Kappa coefficient, the area under the curve (AUC), sensitivity, and specificity of each two screening tools were calculated. Results: Malnutrition was observed in 86.24% of patients based on the PG-SGA and 85.82% based on the NUTRISCORE. When NRI or CONUT were applied, the proportions of malnutrition were < 30%. Patients with malnutrition had lower intakes of energy and protein than normal patients when assessed using the PG-SGA, NUTRISCORE, or NRI. Lower levels of albumin, hemoglobin, total lymphocyte count, and total cholesterol and longer postoperative hospital stays were observed among patients with malnutrition compared to normal patients when NRI, PNI, or CONUT were applied. Relatively high agreement for NUTRISCORE relative to PG-SGA was found; the sensitivity was 90.86%, and the AUC was 0.78. When NRI, PNI, and CONUT were compared, the sensitivities were 23.72% for PNI relative to NRI, 44.53% for CONUT relative to NRI, and 90.91% for CONUT relative to PNI. The AUCs were 0.95 for NRI relative to PNI and 0.91 for CONUT relative to PNI. Conclusions: NUTRISCORE had a high sensitivity compared to PG-SGA, and CONUT had a high sensitivity compared to PNI. NRI had a high specificity compared to PNI. This relatively high sensitivity and specificity resulted in 77.00% agreement between PNI and CONUT and 77.94% agreement between NRI and PNI. Further cohort studies will be needed to determine if the nutritional status assessed by PG-SGA, NUTRISCORE, NRI, PNI, and CONUT predicts the gastric cancer prognosis.

The purpose of this study is to investigate the dietary intakes and nutritional status in total gastrectomized patients. We assessed the nutritional status by dietary intake, anthropometric data and biochemical data. And we also checked the subjective postprandial symptoms and gastrofiberscopy to detect the reflux esophagitis in 22 patients who were free of tumors for more than 1 year after total gastrectomy by the three different reconstruction methods(Loop esophagojejunostomy with A-loop tie/ Roux-en-Y esophagojejunostomy/Roux-en-Y esophagojejunostomy with Paulino pouch). Any patients were not in malnutrition status in respect to biochemical data. By assessing the dietary intake, the average daily calorie intake was 1848.2$\pm$440.2kcal, it was 105.9$\pm$23.8% of energy requirement. But there was weight loss in 21 patients of 22 patients after operation and the weight loss was 12.8% of preoperative weight(61.0$\pm$7.9 vs. 53.5$\pm$6.7kg, preoperatively vs. at the time of study). This may suggest that continuous nutritional care is necessary after total gastrectomy to promote sufficient calorie intake, keeping good nutritional state. There were no significant differences between the methods of reconstruction and dietary intakes or nutritional status. Endoscopic esophagitis was more frequently found in patients of loop esophagojejunostomy than any other reconstruction methods(p<0.001), but it didn't show any effect on the dietary intakes.

The nutritional status of pre-school children is important for both physical growth and functional development. This study investigated the anthropometric, nutrient intakes and dietary quality of the pre-school children living in Asan for planning nutritional education program. The dietary intakes were measured by 2-day 24 hr recall recorded by children's mothers and the anthropometric data were collected by measuring children's weights, heights, and percent body fat at Asan Public Health Center. The children were 161 boys and 129 girls aged 5 and 6 years. When children's nutritional status was determined by their anthropometric status (underweight, normal weight and overweight) determined by z-score (normal range between -1.00 and 1.00), only 1.4% of the children belonged to underweight group while 55.7% and 42.9% belonged to normal and overweight groups, respectively. Significantly higher number of children belonged to overweight group for 5 year-olds. No differences were observed in nutrient intakes, nutrient adequacy ratio (NAR) and index of nutritional quality (INQ) values among nutritional status groups. Intakes of the most nutrients were adequate, but NAR and INQ of calcium and zinc were low. When nutrient intakes, NAR and INQ were compared by sex or age, all nutrient intakes were appropriate except calcium and zinc intakes of 6 year-olds. Nutrient intakes of 5 years were higher than those of 6 years. The mean of nutrient adequacy ratio (MAR) was 0.85 and mean INQ was 1.51 for all participants. The nutritional management program for pre-school children in Asan would be directed differently by age groups and education material should contain contents educating to consume moderate amount of food for 5 year-olds and to increase intake of foods with mineral nutrients such as calcium and zinc for 6 year-olds.

"본 논문은 대한외과학회지 2006년 제70권제1호에 실렸던 논문으로 대한외과학회 편집위원회 승인을 득하고 본 협회지에 게재함. Purpose: Malnutrition has been frequently reported for patients on their admission to the hospital and it has been associated with an increase in morbidity, mortality and the length of the hospital stay. Although a number of screening tools have been developed to identify those patients at risk for malnutrition, there is no' gold standard' for defining malnutrition and the malnourished patients remain largely unrecognized. The aim of this study is to evaluate the efficacy of a nutritional screening tool for use in Dankook University Hospital. Methods Nutritional evaluation was performed for 53 patients who were admitted to the department of surgery and internal medicine between October and December 2004. The screening tool was completed by the ward nurse and the nutritional support team nurse on the same patients within24 hours of admission. The nutritional support team nurse performed the full assessment. The screening sheet included 4 questions regarding body mass index, recent unintentional weight loss, food intake and disease severity. Each answer was scored and a total of 5 was tested as the criterion fey malnutrition. The full assessment included current body weight, recent weight loss, triceps skinfold thickness, mid-arm muscle circumference, serum albumin)in and total lymphocyte count. Malnutrition was defined by 3 or more values below the reference values. The reliability of the screening tool was assessed using kappa statistic. Sensitivity, specificity and accuracy were calculated to evaluate the validity of the screening tool. The receiver operating characteristic(ROC) curve was drawn to choose a cutoff valve that maximizes sensitivity and specificity. Results' The level of agreement between the ward nurse and the NST nurse was good for BMI and food intake and moderate for weight loss and disease severity. The full assessment identified7 patients(13.2%) as malnourished. The screening sheet had a sensitivity of 86% and a specificity of 80%. According to the ROC curve, a score of 5 points provided the best validity. Conclusion The nutritional screening tool is reliable when completed by different observers and it is valid for nutritional assessment.

This study was designed to observe the nutritional knowledge, food behavior, nutritional attitudes and food preference of elderly living in home. Two hundred and thirty elderly were examined on questionnaire. The results of this study are summarized as follows. 1. The average score of their nutritional knowledge was 6.08 (the highest mark was 10.00). The nutrition knowledge score of the elderly live with spouse was higher than those live alone and goes up according to the education degree of elderly and pocket money. The correct answer ratio about a question of geriatric diseases was somewhat higher than another question. 2. The average score of their food behavior was 21.90(the highest mark was 33.00) and the score of the female was higher than that of the male and the college-educated elderly have the highest score. Generally their food behavior was improved by the increasing intake of animal protein and milk. 3. The average score of their nutritional attitude was 11.25 (the highest mark was 15.00) and those of 70~74 age old have the lowest score. And they answered that they are willing to change their food behavior for their health. In this study we expect that the authorities would operate the nutritional education for the prevention of degenerative diseases and the development of the food behavior at a public health center or another groups(no-in-jung) as a part of service for the welfare of elderly. 4. They prefered vegetable foods to animal foods and baking, broiling, and raw foods to the fried foods, and they liked the sweet foods, the fruits, milk and lactic acid beverage as snack or dessert.

The purpose of this study is to evaluate the nutritional status of protein and lipids in the patients with alcoholic liver disease, to find an effective way of dietary management for patients with alcoholic liver disease and to obtain the materials for nutritional education for alcoholics. The subjects consist of 80 patients with alcoholic liver cirrhosis(ALC) and 12 patients with alcoholic fatty liver(AFL). The control group included 57 alcoholics without liver disease(A), 32 patients with viral liver cir rhosis(VLC) and 194 normal(NL). Biochemical evaluation of nutritional status was performed by ana lyzing the profiles of protein and lipids in blood samples. The results are summarized as follows: 1) The frequency of subjects below the normal range of serum total protein was 26.3% in ALC, 16.7% in AFL and 3.5% in A. Serum albumin was lower in 41.3% of ALC. 2) The alcoholics without liver disease showed significantly higher level of serum triglycerides, total cholesterol and LDL cholesterol than the other groups. The alcoholic subjects had lower HDL cholesterol than normal subjects. Overall, the protein and lipids status of the alcoholic subjects in this study was evaluated to be very poor on the basis of biochemical assessments. The results suggest that alcohol abuse and poor dietary intake could cause malnutrition. An extensive nutritional education should be emphasized for the alcohol consuming population. High quality of protein and other dietary intakes from early stage of the disease may be effective in nutritional therapy for the patient with alcoholic liver disease.
