Although it is well known that cancer patients suffer from malnutrition, there are few published studies on malnutrition in outpatients receiving chemotherapy in Korea. This study aimed to evaluate nutritional risk in oncology outpatients receiving chemotherapy and to show the baseline data to set up nutritional management programs for cancer patients. This is a retrospective observational analysis on 1,962 patients referred for nutritional education before or during chemotherapy at Seoul National University Hospital Cancer Center from January 2006 to May 2007. According to a malnutrition screening tool, the proportion of patients having malnutrition risk was 23.0%. In the case of upper gastrointestinal cancer, more than 50% of patients were assessed as being at the risk of malnutrition. They showed more than 7% weight loss compared to their usual body weight and poor oral intake; energy intake was less than 100% of Basal Energy Expenditure(BEE) and protein intake was less than or equal to 0.77 g/kg/d. However, only 6.3% of breast cancer patients had risk of malnutrition and their oral intake was better; energy intake was 121% of BEE, and protein intake was 0.90 g/kg/d. Outpatients receiving chemotherapy had different nutritional risk depending on their cancer site. Nutritional management program should be conducted differently, depending on the cancer site and upper gastrointestinal cancer patients at high risk of malnutrition should basically have nutritional assessment and intervention.

[Purpose] Effective nutritional intervention can help reduce the risk of nutritional problems and improve athletic performance in adolescents. The five A's (assess, advise, agree, assist, and arrange) model is widely used as the theoretical framework for advice on nutrition, smoking, drinking, and physical activity and it recommends that practitioners in primary health care promote behavior change to facilitate positive outcomes. This model has also been useful in understanding the underlying processes of behavior change. This study aimed to develop both a novel evidence-based nutritional intervention protocol, rooted in sound nutritional theory, and a customizable nutritional intervention program to support sustainable healthy eating, enhance nutrient intake, and improve athletic performance in adolescent athletes. [Methods] In this study, we adapted the 5 A's behavioral change model and motivational interview to develop a theoretical framework to help adolescent athletes change their behavior and achieve their goals. [Results] During each step of the 5 A's protocol, a customized nutritional intervention protocol was developed by nutrition experts for each of adolescent athletes. Each plan was developed to improve the eating habits of adolescent athletes through group education and counseling. All nutritional counseling sessions were designed to enable participants to apply nutritional knowledge and practical action plans to their training and competition conditions to enable each of them to achieve individual athletic goals and facilitate self-management. [Conclusion] A theoretical and evidence-based nutritional intervention protocol was developed to identify and address obstacles to healthy dietary habits in adolescent athletes. This could be used as the basis for further studies aimed at improving nutrient intake and athletic performance in adolescent athletes.

The objectives of this study were to investigate 1) the nutritional knowledge, 2) the use of nutritional supplements, and 3) nutrient intakes of male elite bodybuilders (n=20). Participants carried out a comprehensive survey, anthropometric assessment, and 1 day food record. Daily nutrient intakes of the subjects were analyzed using Computer Aided Nutritional Analysis Program (Can-pro 3.0). The mean age of the subjects was 23.4 years. The mean duration of exercise was 5.3 years. The average scores of nutritional knowledge were 71.0%. The subjects were gathered nutrition information from nutrition book (65%), mass communication (50%), friends (50%) and coach (30%) in order. Ninety percentage of the subjects reported that they were taking nutritional supplements. Major reasons for taking nutritional supplements were to improve performance and to build-up muscle. The most frequently taken nutritional supplements were protein powder (85%), multivitamin/mineral (75%), BCAA (60%) and glutamine (55%) in order. The average daily energy intakes of the subjects were 4,248.7 kcal. The mean intake of protein was 370.3 g/day (3.93 g/kg BW). The ratio of total energy intake from carbohydrate, protein and lipid was 51 : 34 : 15. The intakes of most vitamin and minerals through food and nutrition supplements were much higher than those of each nutrient of the RDAs. Especially, vitamin B complex and vitamin C intakes were ranged from 500 to 3,000% of KNHNES. More research needs to be conducted to determine the optimal amounts of carbohydrates, protein, lipid and micro-nutrients for the bodybuilders.

This study was prospectively conducted to investigate any relationship of nutritional status at the time of admission to length of hospital stay and mortality. All patients admitted to the Asan Medical Center between October 13 and November 12, 1997 who met the study criteria were included in the study. Patients were classified as Not-at-risk, At-risk Ⅰ or At-risk Ⅱ based on the levels of serum albumin and total lymphocyte count in a computerized nutrition screening program. Sixty three percent of the patients were classified as Not-at-risk Group, 29% as At-risk Group Ⅰ and 8% as At-risk Group Ⅱ. Significant correlation was observed between nutritional status and LOS (P＜0.01) as well as mortality rate (P＜0.05). The more the patient had the nutritional risk factors, the longer the LOS and the higher the mortality rate were. Further studies have to be done in order to demonstrate cost-effectiveness of medical therapy for the malnourished hospitalized patients.

The purpose of this study was to survey the concern for health, nutrition knowledge, and nutritional attitude of the elementary school children's mothers, to investigate the correlations among them, and to estimate their effects on the growth of their children. The questionnaire was answered by 780 mothers in the Busan area. The concerns over health and nutritional attitude were above average in all items. The perception and accuracy with respect to nutrition knowledge were 90.3% and 77.0%, respectively, and the mean score of the nutrition knowledge was 17.5 on a basis of twenty-five. This indicates that the subjects had a comparatively deep concern for health and good knowledge of nutrition, and professed a relatively desirable attitude. These results indicate a desirable dietary attitude for children as well as parents. The correlation coefficients between nutrition knowledge and a concern for health, and between nutrition knowledge and nutritional attitude were very low. This suggests that the subjects' knowledge of nutrition does not develop into practice. The correlation coefficient was high (r=.610) between the concern for health and the nutritional attitude. In conclusion, the nutrition education program for mothers should be developed to add good practice to knowledge, thus increasing the concern for health, correcting their faulty knowledge of nutrition, teaching the good nutrition, and taking a practical attitude toward the use of their present nutritional knowledge.

Purpose: The purpose of this study was to investigate physical activity of elderly women at senior citizen centers and to identify factors influencing physical activity. Methods: The study was conducted from February 22 to April 20, 2013 for 200 elderly women at senior citizen centers in J City. Levels of physical activity, cognitive function, and nutritional status were measured. Results: The total physical activity amount was $2118.94{\pm}2.36$ MET-min. The average cognitive function score was $21.17{\pm}4.63$, and the average nutritional status score was $24.04{\pm}3.37$. There were significant relationships among physical activity, cognitive function, and nutritional status. In addition, there were significant differences of groups of physical activity by levels of cognitive function and nutritional status. Cognitive function, nutritional status, and age were significantly associated with level of physical activity in elderly women. Conclusion: The results showed many older women were doing moderate physical activity. Physical activity was associated with cognitive function and nutritive conditions. Integrated health promotion program needs to be implemented to increase physical activity level, the cognitive function, and nutritive conditions in elderly women.

Purpose: This study was conducted to evaluate nutritional status, and the effects of lifestyles and depression on nutritional status of elderly people (NSE). Method: The participants were 280 elders who visited the Y city Senior Welfare Center between August 2006 and October 2006. Data were collected using a structured questionnaire that included general characteristics, lifestyle checklist, depression scale, and nutritional risk index. Also, Body Mass Index (BMI) was calculated from height and weight. T-test, ANOVA, Duncan test, Pearson coefficients correlation and stepwise multiple regression were used to analyze the data using the SPSS Win 12.0 program. Results: The NSE mean score was mid level at 5.03 BMI was 23.42 which indicates overweight. Depression was the factor that influenced the nutritional risk index most strongly, accounting for 17.3% of the total variance in the NSE. A combination of significance of health, concerns about health, housing, condition of teeth, activity, and smoking pattern accounted for 29.8% of the variance in the NSE. Condition of teeth accounted for only 3.8% of the variance in BMI. Conclusion: It is necessary to be aware that variance in the NSE can be affected by several factors including depression and lifestyle and that depression is strongly related to poorer NSE.

BACKGROUND/OBJECTIVES: The purpose of this study was to investigate the overall effects of a tailored Dietary Approaches to Stop Hypertension (DASH) nutritional intervention program which included omega-3 fatty acids supplementation, on dietary self-efficacy, dietary knowledge, and dietary behaviors in Korean elderly women with abdominal obesity. Furthermore, we investigated the effects of the program on metabolic syndrome parameters including the antioxidant capacities in these subjects. SUBJECTS/METHODS: A randomized, controlled trial was conducted for 8 weeks. The experimental group (n = 21) received a weekly tailored nutritional program for 8 weeks and the control group (n = 18) received only one educational session. The clinical survey was conducted before and after the intervention period. RESULTS: After the intervention, dietary self-efficacy (P = 0.023), frequency of fruit intake (P = 0.019), and dietary fiber intake (P = 0.044) were higher in the experimental group than in the control group. The oxidative stress (P < 0.001) was lower in the experimental group than in the control group. Moreover, low density lipoprotein (LDL) cholesterol (P = 0.023) had significantly decreased in the experimental group but not in the control group after the intervention. CONCLUSIONS: The intervention program including omega-3 fatty acid supplementation had a positive effect on dietary self-efficacy, dietary behaviors, and oxidative stress among aged women with abdominal obesity.
