Purpose: The purpose of the study was to evaluate the effect of the immediate postoperative nutritional status and calorie adequacy on clinical outcomes in liver transplant recipients. Methods: A total number of 99 patients who received liver transplants were recruited from a tertiary university hospital. Demography, subjective global assessment, clinical outcomes and calorie adequacy were evaluated through personal interviews, electronic medical records and dietary records. Anthropometric measures, body mass index and percent of ideal body weight were also obtained. Results: At admission to the Surgical Intensive Care Unit (SICU), the triceps skinfold thickness and mid-arm muscle circumference were significantly lower in the malnourished group than in the well-nourished group (p<.05, respectively). In the clinical outcomes, transfusion of red blood cells, mechanically ventilated hours, length of stay in the Intensive Care Unit (ICU), length of stay in the hospital, and prothrombin time were significantly higher in the malnourished group than in the well-nourished group (p<.05, respectively). The mechanically ventilated hour was significantly higher in the group with less than 50% of their required energy intake (p<.05). Conclusion: Therefore, it is important to assess the nutritional status of immediate postoperative patients. Furthermore, studies on nutritional interventions are urgently needed to provide adequate nutritional care for patients in ICUs.

Background: New alternative types of pet foods such as raw and cooked homemadestyle diets containing human food ingredients have been introduced due to a trend of pet humanization and diversification of consumer needs. Objectives: To evaluate nutritional adequacy of new alternative types of dog foods containing human food ingredients as maintenance diets for dogs. Methods: Eleven homemade-style foods for adult dogs were purchased from online channel in Korea and analyzed to evaluate nutritional adequacy for adult dogs. Nutrients analyzed included crude protein, amino acids, crude fat, fatty acids, and minerals. Results: Crude protein and amino acids in all products satisfied Association of American Feed Control Officials (AAFCO) requirements. Crude fat in one of 11 products did not meet AAFCO requirements. The most deficient minerals were selenium (10 of 11, 90.9%), copper (five of 11, 45.5%), zinc (five of 11, 45.5%), potassium (three of 11, 27.3%), calcium (three of 11, 27.3%), iron (two of 11, 18.2%), and magnesium (one of 11, 9.1%). Six products were not in the range of the recommended Ca:P ratio in AAFCO dog food maintenance nutrient profiles. Conclusions: This study performed nutritional evaluation of raw and cooked homemadestyle foods as maintenance diets for adult dogs. Some nutritional inadequacies were observed including some minerals, Ca:P ratio, and omega-6:omega-3 fatty acid ratio, although three products (26.2%) satisfied the AAFCO standard except selenium. Overall, the data suggest a need for accurate nutritional adequacy statement for consumers based on proper methods to validate the formula.

Physiological changes that affect nutrient absorption and utilization occur in older adults, and the collection of nutritional information is an important part of examining the nutrition and health issue. A nutritional survey using the 24-hour recall method was performed to identify nutritional quality and leading patterns of food group intake for protein, vitamin C, P and Fe were over 1, whereas those for vitamin A, $B_1$, $B_2$, niacin and Ca were below 1. The MAR(Mean Adequacy Ratio) was relatively low(0.75). The percentage of energy from carbohydrate, protein, and fat was 65.1, 15.6, and 19.5, respectively, thus the quantities of energy source were ideal. The Older subjects revealed poorer nutrition quality than the younger subjects did. The food group intake pattern of the elderly was not diverse, only 9% of them consumed all food groups in a day. These results suggest that nutritional guidelines for older Koreans should focus on the maintenance of adequate energy intake. In addition, selection of foods with high protein and calcium, such as dairy food, should be emphasized, particularly in the older elderly. Nutrition programs should target individuals at risk of not receiving enough nutrients, like the oldest elderly, and persons with lower education.

The purpose of this study was to investigate the changes in nutritional status of gastrectomy patients. The anthropometric and biochemical data were measured at pre-operation, at discharge, 1 month after discharge, and 3 months after discharge. Nutrient intake levels, nutrients adequacy ratio (NAR), mean adequacy ratio (MAR), and the proportion of patients with intake levels inferior to those of dietary reference intakes (DRIs) were analyzed at discharge, 1 month after discharge, and 3 months after discharge. Finally, the data on 23 patients (15 male and 8 female) were collected and used for statistical analysis. Fifteen patients underwent subtotal gastrectomy, and 8 patients underwent total gastrectomy. Compared to pre-operation, body weight and body mass index of subjects significantly decreased at discharge, 1 month after discharge, and 3 months after discharge (P<0.001). Serum albumin (P<0.001), total lympocyte count (P<0.001), total cholesterol (P<0.001), hemoglobin (P<0.001), hematocrit (P<0.001), and mean corpuscular hemoglobin concentration (P<0.05) were significantly different between pre-operation, at discharge, 1 month after discharge, and 3 months after discharge. The proportions of patients with lower nutrient intake levels than DRIs were substantial. MAR at discharge, 1 month after discharge, and 3 months after discharge were 0.70, 0.80 and 0.91, respectively. Especially, the NARs of folate, niacin, vitamin $B_2$, vitamin C, and zinc were all low. Considering the various nutritional problems of gastrectomy patients, systematic medical nutrition therapy is needed after gastrectomy.

The purpose of this study was to investigate nutrients intakes and nutritional quality of Adults and Elderly People in an island area (Wando). A three-day dietary intakes survey, using a 24 hour recall method was obtained from 187 subjects aged 46 to 84 (mean age 65.3) living in an island area (Wando). Nutient intakes were analyzed using CAN-Pro soft program and compared to Korean RDA. The quality of nutrients was assessed by analyzing nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ). The average daily mean energy intakes were 1869.0 kcal for males and 1943.9 kcal for females, respectively. Daily intakes of protein for males and females were 28.0 and 30.4 g and those of fat were 31.5 and 28.51 g, respectively. Nutrient consumed below $75\%$ of Korean RDA was protein, vitamin A, Ca and Zn in both males and females. Average CPF ratio of males and females were 78.8 : 6.0 : 15.1 and 80.0 : 6.4 13.4, respectively. Energy intake ratio from protein was significantly higher in over 60 years males. Carbohydrate dependency decreased with age. Protein dependency increased with age. Nutrient adequacy ratio (NAR) of energy, protein vitamin A and vitamin E were increased with age in males. The mean adequacy ratio (MAR), an index of overall dietary quality, were not significantly different by age group. Average MAR for males and females was 0.77 and 0.78, respectively. The index of nutritional quality (INQ) showed the tendency to decrease with age. Especially, there were significantly decreases in INQ of all nutrients, except protein, with age. Based on these results, it is evident that people in the island area did not consume enough nutrients. Specially, dietary intake of protein, vitamin A, vitamin E, and Ca were not adequate.

Objectives: Maintaining a balanced diet and thus health is crucial for adolescents, and the first step for balanced diet practice is meal planning. Adolescents, however, find it difficult to plan their meals. This study thus was set out to design an easier way of planning meals for adolescent girls. Methods: A dish-based target pattern for adolescent girls was tabulated, and validity of this was examined. Meal plan applying a dish-based target pattern was prepared by 150 female middle school students, and nutritional adequacies of those meal plans were examined. Validity and adequacy were tested by energy content, energy contribution ratio, nutrient adequacy ratio (NAR), probability of nutrient inadequacy, index of nutritional quality (INQ) calculation. Results: A dish-based target pattern with 11 dish groups was validated for nutritional adequacy. Though the NAR of calcium was 0.96, the INQ of calcium was 1.00. The average energy supply from the meal plans was 2,379 kcal, higher than the estimated energy requirement of a female middle school student, but the energy contribution ratio of carbohydrates, proteins, and fats were all adequate according to the acceptable macronutrient distribution range (AMDR). NAR of all nutrients examined were 1.0, except for calcium. The NAR and INQ of calcium were 0.87 and 0.75, respectively, and the meal plans at risk for calcium inadequacy was 19.30%. Conclusions: A dish-based target pattern proposed for adolescent girls was valid, but the meal plan prepared by female middle school students using this approach was high in energy and low in calcium supply. To cut down the energy supply from the meal plan, it is necessary to recommend dishes low in fat and use low fat cooking methods. To increase the calcium supply, it is important to recommend seaweed and legume group dishes with higher Ca INQ food items.

This study intended to evaluate the validity of the simple nutrition screening test that had been developed with the elderly living in Cheongju as a subject. Nutrition screening score(NSS) and reference standards for nutritional and health status(nutrient intakes, mean adequacy ratio, perceive health, and serum albumin, hematocrit, and hemoglobin) were estimated by using the date obtained in 1996 from the 174 elderly living in Taejon, Statistical analysis showed significant correlations between mean adequacy ratio(MAR) and NSS(r=0.341) and also between NSS and biological indices such as albumin and hematocrit, Around 65-75% of the elderly with perceive health and low level of serum albumin, hemoglobin and hematocrit had NSS$\leq$ll. Sensitivity, specificity, and positive predictive values(PPV) were calculated from the crosstabulation of the three categories of NSS(high, moderate, and low nutritional risk) and low categories MAR(< 0.75, undernutrition;$\geq$0.75, normal) to validate the cut-off point for high or low nutritional risk by NSS. It was suggested that point l1 was appropriate as a criterion to determine high risk of undernutrition, but point 16 was better than 17 as criterion to determine low nutritional risk in the Taejon elderly. When point ll was used as a criterion of high nutritional risk, sensitivity, specificity, and PPV are 59.5, 60.5 and 82.1 respectively. When point 16 was used as a criterion of low nutritional risk, sensitivity, specificity, and PPV are 25.6, 95.4, and 64.7%, respectively. In conclusion, nutrition screening test that had been developed can be a simple, easy, and proper instrument to classify the high risk group of undernutrition. A further validation study seems to be required among other groups of individuals for the screening test to the finalized as a more valid instrument identifying Korean elderly at nutrition and health risk(Korean J Nutrition 33(8) : 864-872, 2000)

The objectives of the study were to provide the basis for nutrition education for consumers so that they could select nutritious and balanced fast foods and to promote menu items for fast foods franchisers by addressing nutrition and health. Nine franchisers (3 hamburger, 3 noodles and 3 chicken) were surveyed in terms of their nutritional concern for product development, and 360 consumers were interviewed at 36 fast food chains to assess their perceptions of nutrient adequacy of fast foods. The taste of foods was being addressed most when developing menu items in surveyed franchisers but nutrition and variety of menu were being considered least. Hamburger chain franchisers showed greater nutritional concerns in promoting menu items than noodles or chicken chain restaurants. Their nutritional concerns include utilization of nutritional information as promotion of menu item, providing nutrition information of menu item to consumers, and evaluating nutritional balance of their menu items. As a result of INQ evaluation of combined fast food selected by consumers for a meal, the desirable case of both nutritious and adequate in calorie was 14.7%, nutritious but lack in calorie was 44,1%, adequate in calorie was 24.5%, and undernutritious and lack in calories was 21.6%, 45.7% of snack selected by consumers had more calories than needed for a meal.

This study was performed to assess the nutrient intakes and diet quality of rural middle school students provided with and without the national school lunch program(NSLP). The data on dietary intakes were obtained by using food record method questionnaires which were collected from 340 rural middle school students provided with(n=177) and without (n=163) NSLP. Diet quality was accessed by NAR(nutrient adequacy ration), MAR(mean adequacy ration), and INQ( index of nutritional quality). Total energy intakes of the boys were 2123 kcal with NSLP and 1857 kcal without NSLP. Total energy intakes of the girls were 1913 kcal with NSLP and 1814 kcal without NSLP. Phosphorus, vitamin A, vitamin E, ascorbic acid, thiamin, riboflavin, and niacin intakes were above the RDA in the NSLP group. For those without NLSP, phosphorus, vitamin E, thiamin intakes were above RDA, however, calcium, iron vitamin A, vitamin $B_6$ were less than the RDA. The mean adequacy ration(MAR), an index of dietary quality was 0.69(with) 0.62(without) for males and 0.62(without) for females The indexes of nutritional quality(INQ) were over 1 for most nutrients except calcium, vitamin A, vitamin B$_2$ and zinc. The study showed that total daily energy and nutrient intakes were significantly higher in students provided with than those without school-lunches. Thus, the school-lunch program is recommenced and necessary to improve the nutritional status of middle school students.
