Objectives The purpose of this study was to compare sleep quality and chronotype by Sasang constitution and examine the relationship with nutritional status. Methods This study used 672 follow-up data from the Korean Medicine Daejeon Citizen Cohort study (KDCC). Demographic, Sasang constitution, sleep quality, chronotype, and nutritional status evaluation were conducted based on questionnaires. Multiple linear regression analysis was used to confirm the relationship between sleep quality and chronotype according to Sasang constitution and nutritional status. Results The relationship between sleep quality and chronotype by Sasang constitution and nutritional status is that Taeeum nutritional index is related to sleep quality (adj. B = -0.46, 95% CI = -0.79 ~ -0.12) and chronotype (adj. B = 0.38, 95% CI = 0.24 ~ 0.52), and Soeum and Soyang showed an association between nutritional indices only in chronotype (adj. B = 0.43, 95% CI = 0.23 ~ 0.63 in SE, adj. B = 0.55, 95% CI = 0.38 to 0.73 in SY). Conclusions This study confirmed the relationship between sleep quality and chronotype and healthy eating habits. For a balanced nutritional status, overall sleep management is necessary. Based on the results of this study, we intend to use it as basic data on the impact of the relationship between nutritional status and chronotype by Sasang constitution on health.

The purpose of this study was to evaluate the dietary habit, nutritional condition and quality of everyday meal for college students. The number of the subjects was 102 and they were divided into three groups by their residing types; students living with their parents (n=34), students living in dormitory (n=34) and students living independently off the campus (n=34) Questionnaire, 24hour dietary recall for food intakes, and body composition analysis were used. SPSS program was used for the statistics. In general health matter, the average age for each group of students was $21.2kg/m^2$, $20.9kg/m^2$, and $21.9kg/m^2$ respectively. And heights, weights, muscle mass, body fats and BMI were not significantly different between groups. Results on dietary habit showed that students living with their parents had better meal pattern and regularity for breakfast than other groups. Also, for dietary evaluation, students living with their parents showed better extent of intake of milk than other groups. Evaluation on nutrients intake showed that amount of calcium, vitamin $B_2$, folic acid intake in student living independently off the campus were lower than those of the other groups(P<0.05). And MAR(Mean Adequacy Ratio) was not significantly different between groups, however INQ(Index of Nutritional Quality) and NAR(Nutrient Adequacy Ratio) of calcium were lower in off the campus group than other two groups. In conclusion, students living independently had worse eating habits and showed lower intake of calcium than those living with their parents or living in a dormitory. Therefore nutritional education for improving well-balanced dietary habits and optimal intake of nutrients are required especially for students living independently off the campus.

The protein nutritional quality of foods has become an important factor to food processors with the advent of nutritional labeling regulations for foods. Then, as is true today, the officially approved assay for protein nutritional quality was the rat based protein efficiency ratio(PER) bioassay. The PER bioassay requires a minimum of 28 days to performe, and is therefore not applicable to routine quality assurance use by the food industry. Within the past ten years there has been a research emphasis placed on the development of rapid, inexpensive, biological and/or chemical based assays for protein nutritional quality. It was hoped that if a rapid assay could be developed and thoroughly tested, it could be used in lieu of the PER bioassay in the day-to-day quality assurance screening of food ingredients and products. The rapid assays developed in the hope of attaining this goal have been based on microorganisms, proteolytic enzymes, and amino acid profiles, as well as combinations of the above. In this review, it will be described and briefly discussed many of procedures which had contributed conceptually as well as practically to the development of in vitro methods for the evaluation of protein quality. Special emphasis will be placed on the C-PER(computed protein efficiency ratio) assay which combines data from in vitro protease digestion and amino acid composition to predict protein nutritional quality designed by Satterlee et al. (1980), and the DC-PER(discriminant computed PER) which is a method of estimating protein quality based on rat assay and in vitro digestibility obtained using solely essential amino acid data will be also introduced.

BACKGROUND/OBJECTIVES: Malnutrition in the elderly is a serious problem, prevalent in both hospitals and care homes. Due to the absence of a gold standard for malnutrition, herein we evaluate the efficacy of five nutritional screening tools developed or used for the elderly. SUBJECTS/METHODS: Elected medical records of 141 elderly patients (86 men and 55 women, aged $73.5{\pm}5.2years$) hospitalized at a geriatric care hospital were analyzed. Nutritional screening was performed using the following tools: Mini Nutrition Assessment (MNA), Mini Nutrition Assessment-Short Form (MNA-SF), Geriatric Nutritional Risk Index (GNRI), Malnutrition Universal Screening Tool (MUST) and Nutritional Risk Screening 2002 (NRS 2002). A combined index for malnutrition was also calculated as a reference tool. Each patient evaluated as malnourished to any degree or at risk of malnutrition according to at least four out of five of the aforementioned tools was categorized as malnourished in the combined index classification. RESULTS: According to the combined index, 44.0% of the patients were at risk of malnutrition to some degree. While the nutritional risk and/or malnutrition varied greatly depending on the tool applied, ranging from 36.2% (MUST) to 72.3% (MNA-SF). MUST showed good validity (sensitivity 80.6%, specificity 98.7%) and almost perfect agreement (k = 0.81) with the combined index. In contrast, MNA-SF showed poor validity (sensitivity 100%, specificity 49.4%) and only moderate agreement (k = 0.46) with the combined index. CONCLUSIONS: MNA-SF was found to overestimate the nutritional risk in the elderly. MUST appeared to be the most valid and useful screening tool to predict malnutrition in the elderly at a geriatric care hospital.

Objectives: This study investigated the menu and nutritional contents of convenience store lunchboxes, and evaluated the nutritional content by meal type, price, and store brand. Methods: In September 2019, 93 convenience store lunchboxes from the top five franchise stores were purchased. Relevant information on price, food weight, food ingredients, cooking methods, and nutrition labeling were subsequently collected. Nutritional content was evaluated based on the daily value (DV) and Index of Nutritional Quality (INQ), and energy contribution of carbohydrate, protein, fat, saturated fat and sugar was compared with the recommended range. Results: Most lunchboxes included the food groups; grains/starches, meats/fish/eggs/legumes, and vegetables. However, none provided fruits, and only a few lunchboxes provided milk/milk products. Stir-frying, deep-frying, and pan-frying were the most frequent methods of cooking. The average energy content of the lunchboxes was 736.6 kcal, whereas the average contents of protein, fat and saturated fat were higher than 40% of the DV, and sodium content was 66.8% of the DV. The contents of most nutrients in traditional type lunchboxes were higher, as compared to nutrients in onedish type lunchboxes. Considering pricing of lunchboxes, protein and sodium contents were higher in the higher-priced lunchboxes as compared to lower-priced lunchboxes, but there were no differences in the INQs. The contents of energy, protein, fat, saturated fat, and cholesterol significantly differed by brand. Conclusions: Our results indicate that convenience store lunchboxes contain high levels of protein, fat, saturated fat, and sodium. The nutritional contents differed by meal type, price, and store brand, and higher price did not imply higher nutritional quality. We propose the need to educate consumers to check nutrition labels and purchase appropriate lunchboxes. Manufacturers also need to make efforts to reduce the amounts of fat, saturated fat, and sodium, and not provide protein in excess.

Special nutritional foods are one category of processed foods. In this category, 5 different food standards are defined in the current rule of the Korean Food Code ; that is, infant formulae, complementary foods for infants and young children, foods nutrient supplementation, processed dietary fiber-based foods, and foods for special dietary uses. The major differences between the special dietary uses. The major difference between the special nutritional foods and the other processed foods is that the special nutritional foods are characterized by their dietary uses for specific population groups rather than food ingredients or manufacturing and processing techniques which characterize and distinguish most of other processed foods. Although several countries establish similar standards for this type of foods, they use different legal names such as foods for special dietary uses(U.S.A., CODEX, Japan), foodstuffs intended for particular nutritional uses(EC), or special purpose foods(Australia). In addition, there are some other differences in the definitions for these food types and categorization of food types among countries. The major difference in the definitions is the description of 'special dietary uses' by specifying certain population groups whose nutrient requirements are different from those of ordinary men due to physiological or physical conditions and therefore may not be sufficiently met by consuming ordinary foods. The categorization of this type of foods is based on the type of dietary uses in the other countries, whereas we include foods simply supplemented with nutrients or foods having certain components such as dietary fibers even if these foods types do not have special dietary sues. Recently, a revision of standards for special nutritional food has been proposed. However, the description of 'special dietary uses' is not clearly indicated in the definition, and some food types which should not be categorized into the special nutritional foods still remain in this category. In order to correct these problems, the standard of food labeling in the Food Safety Law needs to be revised along with revision of food standards in the Food Code.

A functional ability and adequate nutritional status are the major determinants of health status, Self-rated health (SRH) is a worldwide method to assess health status and it is recognized as a predictor of morbidity and mortality in the elderly, This study was designed to evaluate the functional ability and nutritional risk according to SRH in the elderly. Four hundred nine free-living elderly people (118 male, 291 female), aged $\geq$ 65 years were interviewed by trained interviewers using structured questionnaires including demographic information, SRH, anthropometric measurements, functional ability, general health status, and nutritional risk. SRH was divided into three status such as “Good”, “Moderate” and “Poor” status. And all the data were analyzed by oneway ANOVA, spearman correlation, and x$^2$ analysis using SPSS 9.0 version at p 〈 0.05. Of all the subjects, 48.9％ perceived their health status as “poor”, and their functional abilities (activities of daily living, instrumental activities of daily living) were more impaired than their counterparts (“good” and “moderate”). Poor self-rated health was also related to: a higher prevalence of illnesses (p 〈 0,001) especially in hypertension, arthritis. Self-rated health was significantly related to food security (p 〈 0.001), food enjoyment (p 〈 0.001) ,and nutritional knowledge (p = 0.0 13). Also NSI checklist total score was the highest in “poor” health status (p 〈 0.001). Better self-rated health was related to better food security, and better food enjoyment. However, smoking, alcoholic intake, exercise, eating behaviors, and demographic characteristics were not significantly different among the three SRH status. SRH was closely related to chronic diseases, functional ability, and nutritional risk in the elderly. Therefore, public health strategies for the elderly should be focused on the elderly who are “poor” in SRH, to improve nutritional status and functional ability, and to reduce risk factors of chronic diseases.
