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.

The purpose of this study was to investigate the dietary habits, the nutritional knowledge and the consumption patterns of convenience foods of 618 university students located in the Gwangju area, from November twentieth to November thirtieth, 2002. The subjects included 301 males (48.7%) and 317 females (51.3%). This survey was conducted using a self-administered questionnaire. The percentage of students who were underweight, normal and overweight based on their body mass index (BMI) was 3.7, 88.0 and 8.3 far the males, and 29, 71 and 0 for the females, respectively. Most students (73.8%) skipped breakfast. This was because of lack of time (65.1%) of the cases. Self-reported eating habit problems were eating irregular meal (52.4%), overeating (21%), prejudiced meal (12.4%) and skipping meal (7.4%). The type of favorite snack was biscuit (31.9%) and cup Ramyon (31.9%). The rates of alcohol drinking in male and female students were 88.0% and 85.8% respectively, and the rates of smoking were 35.9% and 28% respectively. Males ate fiequently cup Ramyon (2.08 $\pm$ 2.95), fries (pork cutlet, fried potato) (1.91 $\pm$ 2.58), Ramyon (1.81 $\pm$ 3.00) and kimbab (1.70 $\pm$ 3.17) more frequently, while females ate kimbab (2.25 $\pm$ 3.26), cup Ramyon (1.89 $\pm$ 2.09), fries (pork cutlet, fried potato) (1.77 $\pm$ 2.67), Ramyon (1.46 $\pm$ 1.1.95) and fish paste (1.45 $\pm$ 2.22) more frequently. The nutritional knowledge score was higher in females than in males. The mean consumption patterns of convenience foods of students living in home were lower than that of students living in dormitory and boarding w/cooking. When the amount of pocket money available and the body mass index increased and the nutritional knowledge level was low, the mean consumption of convenience foods increased. The mean consumption of convenience foods correlated negatively with nutritional knowledge (p < 0.01). Therefore, nutritional education for university students is needed so as to improve their health and nutritional education program should be developed to meet the various needs of these students.

Purpose: This study aimed to investigate the nutritional status of liver transplantation (LT) recipients and explore certain factors that influence nutritional status, including dietary patterns and physical activities. Methods: This was a cross-sectional, descriptive study. The subjects included 211 LT recipients at a medical center outpatient clinic located in Seoul, Korea. The nutritional status, dietary patterns, and physical activities of each subject were measured using the body mass index (BMI), Mini Dietary Assessment (MDA), and Global Physical Activity Questionnaire. Independent t-test, one-way analysis of variance, and multiple linear regression analysis were used to analyze the data. Results: The percentages of living and deceased donor LTs were 81.0% and 19.0%, respectively. The mean BMIs pre- and post-LT were 23.88 and $23.16kg/m^2$, respectively, and the average MDA score was 36.55. More than 60.0% of the subjects had a moderate or high level of physical activity. In multivariate analysis, a higher BMI before LT (${\beta}=.72$, p<.001), a lower Model for End-stage Liver Disease (MELD) score (${\beta}=-.18$, p<.001), and being male (${\beta}=-.10$, p=.024) contributed to better nutritional status post-LT. Patients within six months of LT were less engaged in muscle exercises than those post six months of LT (p=.020). Conclusion: LT recipients in Korea have good nutritional status and a good level of physical activity. To improve recipients' post-LT nutritional status, the pre-LT nutritional status should be considered, particularly in those with a higher MELD score. In addition, physical activity including muscle-strengthening exercises should be encouraged from an earlier stage.

BACKGROUND/OBJECTIVES: Adequate nutritional intake is essential for good health and well-being. We aimed to compare the nutrient intake from homemade meals, meals sourced externally ("eating out"), and meals from workplace foodservices, as well as the potential association between foodservices used and nutritional quality among adult Korean workers. SUBJECTS/METHODS: We used data from the Korea National Health and Nutrition Examination Survey, a nationwide cross-sectional survey on the health and nutritional status of the Korean population. Data from 6,845 workers aged 20-64 years were included. A survey on dietary behavior and nutrition was conducted using the 24-h dietary recall method. Nutritional quality was examined using the index of nutritional quality (INQ) score. Higher INQ scores reflected poorer nutritional quality, with insufficient intake of a higher number of nutrients. Multivariate linear regression was used to identify the association between the foodservices used and INQ scores after adjusting for other covariates. RESULTS: We found that foodservice users exhibited a higher 1-day intake of total energy and macronutrients (all P < 0.05) and lower INQ scores (P < 0.01) than non-users. The INQ scores for total daily meals decreased with the frequency of foodservice use (P < 0.01). A significant association was observed between the non-use of foodservices and INQ scores (β = 0.29, P < 0.01) after adjusting for other covariates. CONCLUSIONS: The use of workplace foodservices contributed to higher dietary nutritional quality among workers. This study highlights the importance of expanding the scope of workplace foodservices to promote higher nutritional quality and healthy dietary habits among workers.

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.

The purpose of this study was to identify the factors that related to obesity among 6th grade elementary school girls. The study subjects were 337 girls residing in Seoul. Not only variables of nutritional environment such as eating habits, health related behavioral variables, nutritional feeding methods during infancy, and genetic factors but also sexual maturity had been included as a obesity related factors. Association between obesity and related variables were analyzed by $x^2$(Chi-square) test. The obesity prevalence of the study subjects were 16% based on Röhrer Index(RI). Fifty-three percent of the study subjects experienced menarche at the time of data collection. Result of analysis showed that not only the nutritional enviromental variables such as eating habits, specific food preferences, and habit of exercise but also genetic factors did not show any statistically significant association with obesity. Above finding may imply that more variables other than the variables included in this study might have influenced on the obesity of the children. However sexual maturity in term of breast development showed significant association with obesity.

This study was designed to obtain the information concerning food intake, dietary habits, functional status, health condition and cognitive status of the elderly using public health center in Ulsan area. The subjects of this study consisted 154 elderly persons aged 60~82 years. Interviews were conducted using the health habits and food frequency questionnaires to provide basic information for nutrition education program. We evaluated the current food intake, dietary cholesterol intake (cholesterol index), functional status, cognitive function and blood analysis of the subjects. The results of this study were as follows : Mean age of the subjects was 68.7 $\pm$ 6.7years. The average cognitive status score of the subjects was 7.9 $\pm$ 2.0 (full score was 10.0). Male had a higher cognitive status score than female. There was significant difference between cognitive status score and age, education level, pocket money, physical activity and living condition. The subjects who had a higher cognitive status score ate more fish and meats group and milk and milk products than the subjects had a lower cognitive status score. And hemoglobin level, serum triglyceride, HDL-cholesterol and atherogenic index affected to cognitive status while fasting blood glucose and LDL-cholesterol did not any effect on cognitive status. These results have demonstrated that various socioeconomic variables and food intake pattern and nutritional status affect on cognitive status with aging and suggest that proper nutrition education and adequate nutrient intake in quality and quantity are essential in maintaining cognitive status in later life.

Objectives: The aim of this study was to compare the nutritional intake and Diet Quality Index-International (DQI-I) of gynecological cancer survivors and normal women. Methods: This study compared the anthropometric indices, dietary behavior, nutritional intake, and DQI-I in women with previous history of breast or uterine cancer [Gynecological cancer survivors group (GCSG, n=126)] and normal women [Normal control group (NCG, n=7,011)] using the 2013~2016 Korea National Health and Nutrition Examination Survey data. Results: Body mass index and waist circumference were lower in the GCSG compared the NCG. The frequency of skipping breakfast and eating out was higher in the NCG compared to GCSG. Energy and fat intake were significantly higher in the NCG than in the GCSG, whereas intake of all minerals and vitamins (excluding thiamine), and dietary fiber intake were higher in GCSG. It was observed that the fatty acid intake of the GCSG was significantly lower than that of the NCG. The diet quality evaluation using DQI-I results showed that GCSG was higher in the "within-group" diet variety and adequacy of vegetable group than the NCG, whereas the intake level of the fruit group was higher in NCG. Besides, protein, calcium, and vitamin C intake were higher in the GCSG than in the NCG. The GCSG showed higher levels of total fat and saturated fat moderation than the NCG, whereas cholesterol moderation showed the opposite results. The results of DQI-I comparison according to the cancer survival years showed that the overall score and scores related to diet adequacy and balance were higher in the below 5-year group, whereas the over 5-year group scored higher in terms of moderation of diet. Conclusions: The results of this study suggest that a chronic disease based management approach is needed in cancer survivors. The study provides important data which can help in the preparation of guidelines for long-term lifestyle and diet management, in these patients.

The purpose of the study was to investigate nutritional status of chronic obstructive pulmonary disease (COPD) patients and to find out the differences according to the stages of disease. From March to October, 2006, 41 stable male patients of mild to severe COPD patients were recruited from Seoul National University hospital. The patients' of body weight and fat free mass were assessed by bioelectrical impedance analysis. The nutritional status of the patients was also assessed by 3-day recall, index of nutritional quality (INQ), dietary diversity score (DDS), dietary variety score (DVS), food group index pattern and dietary quality index (DQI). The total of 41 patients were classified into three groups, stage I, stage II and stage III groups according to the classification of Global Initiative for Chronic Obstructive Lung Disease (GOLD) standard. The mean age of the patients in each stage were 67.2-66.9 years showing no significant difference. The ratio of $FEV_1$/FVC were $57.5{\pm}7.3$, $46.9{\pm}7.6$ and $38.2{\pm}6.8%$, respectively showing significant differences according to the stages of disease. The fat free mass of the stage II ($48.2{\pm}4.7kg$) and III ($47.3{\pm}4.5kg$) was significantly lower than that of stage I ($53.1{\pm}6.9kg$) patients. There were significant correlation of fat free mass with $FEV_{1}$, and BMI (body mass index) with $FEV_{1}$/FVC ratio (p < 0.05). COPD patients showed the diet-related clinical symptoms of anorexia, dyspnea, dyspepsia, and chewing difficulty. Daily intakes of calorie, K, vitamin $B_2$ and folate of the patients were very low ($83.8{\pm}20.7%$, $58.9{\pm}14.4%$, $70.7{\pm}19.6%$ and $74.4{\pm}10.2%$, respectively) however, they did not significantly different according to the stages of disease. Daily intake of calcium was significantly lower in the stage III patients (p < 0.05). The mean scores of dietary variety score was significantly lower in the stage III patients (p < 0.001). Dietary quality index of the patients were not different among the stages of disease and the scores indicated poor quality of diet. As a summary, we found that body fat free mass, regularity of exercise, frequency of having snacks and dietary variety score were significantly associated with the severity of chronic obstructive pulmonary disease.

The purpose of this study was to investigate the relationship between obesity indices, nutritional knowledge, nutritional intake status, and some blood parameters in obese middle-school students. Anthropometric measurement, 24-hour recall for dietary intake, blood analysis and Questionnaire response including nutritional knowledge, nutritional attitude, and self-satisfaction were conducted in 42 obese middle-school students (28 male and 14 female) participated in the nutritional camp program carried by Bucheon district public health center in Kyunggi-do. The mean age of subjects was 13.9 years. The average body weight, BMI, obesity index, WHR and percent body fat were 75.5 kg, 29.1 kg/$m^2$, 30.1, 0.89 and 33.3% in male subjects, and 67.8 kg, 27.5 kg/$m^2$, 25.3, 0.81 and 34.6% in female subjects. The average nutritional attitude, the self-satisfaction and the nutritional knowledge scores were no significant difference between male and female subjects. Average intake of energy were 85.5% of RDA in males and 98.1% of RDA in females. The percentage of energy from fat was higher in both male (29%) and female (26%) subjects than recommended level. Calcium, iron, zinc, vitamin A, vitamin B$_2$, vitamin C, niacin and folate intakes were below the RDA for them. In the results of correlation analysis, body weight, BMI and obesity index were positively correlated with systolic blood pressure and cholesterol intake. There was a negative correlation between percent body fat and nutritional knowledge. Body weight was negatively related to HDL-cholesterol, whereas it has positive relation with RBC, hemoglobin and hematocrit. BMI and obesity index were negatively related to HDL-cholesterol, but positively related to RBC, respectively. WHR showed positive relationship with serum GPT, glucose and MCV.
