High serum cholesterol level is a major risk factor for coronary heart disease(CHD). Nutrition therapy of hypocholesterolemic diets with increased physical activity is the essential step in the treatment of the hypercholesterolemic patients. The purpose of this study was to evaluate the short-term effect of intensive dietary therapy combined with regular exercise in lowering serum cholesterol level. Seventy three hypercholesterolemic outpatients(mean: 268.0$\pm$24.7mg/dL), aged 34 to 73(mean: 56$\pm$9.8yrs), who visited cardiology OPD of Yonsei Cardiovascular Center from April through October, 1998 were studied. Anthropometric measurements, usual nutrient intake survey using semiquantitative food frequency questionnaire, and daily nutrient intake analysis were performed. The nutrition counseling for the hypocholesterolemic diet and exercise therapy was performed individually. After a 4 week intensive dietary therapy, comparisons of body weight, nutrient intakes, and blood lipid concentrations were evaluated for the hypocholesterolemic effect of intensive diet therapy. After 4 weeks of intensive diet therapy, significant reductions in percent ideal body weight(p<0.01), saturated fat intake(p<0.01), and cholesterol intake(p<0.01) were observed. There were significant reductions in serum total cholesterol and LDL-cholesterol levels after 4 weeks of therapy by 8.1%(p<0.01) and 9.7%(p<0.01), respectively. Our results showed that intensive dietary therapy was effective in reductions of serum total and LDL-cholesterol levels. The goal for this dietary modification should not be temporary but rather be permanent in eating behavior accompanied by appropriately increased physical activity.

Objectives: This study was performed to investigate the nutritional status, health conditions, eating habits and experience and demand for nutrition dietary management of senior citizens. And these data are formed foundation of development of nutrition dietary management education program and contents in welfare facilities for the aged. Methods: We visited 3 public health centers, 3 senior citizens centers, and 4 welfare centers in Seoul, Gyeonggi-do, Chungnam province, and Daejeon area and carried out interview by semi-structured questionnaire for senior citizens older than 65 years who use those facilities. Results: The study included 17%, 30.7% and 52.3% of senior citizens from public health centers, seniorcitizen centers and and welfare centers, respectively. The age range of 43.9% of the population was 65-74 years and and 56.1% were older than 75 years. We observed that 83.2% of subjects took some medicines due to diseases that they have and 58.0% took prescription medicines for hypertension. The thing that they considered the most when selecting food was 'the taste'(p<0.05). Regarding the level of practice to keep the dietary life, they answered more than 'average' for most of items but answered less than 'average' for lot of salt intake, drinking, exercise. For the experience of nutrition dietary life education, only 19.8% answered 'Yes' and the service for nutrition dietary life management showed the highest score in the demand for 'provide nutritious food'. For the size of consulting group for nutrition/dietary life education, the public health center and welfare center preferred a larger group size but the senior citizens center preferred a smaller group. With regard to who will carry out the consulting, the demand for dietitian was the highest and the operation type showed the high demand in the order of consulting, education. The contents that they want to have consultation in nutrition dietary life education were diet therapy for diseases and the ordinary diet therapy for health. Conclusions: This study suggested the management of nutrition dietry life necessitates qualitative measures according to the different types of welfare facilities. For these, it is in need of development of counseling and education program included therapy for disease. Above all, the policy to secure dietitian of welfare facilities for the aged to perform these should be achived.

The purpose of this study was to investigate the effects of body weight control program for obese children. The program included nutrition education, exercise and behavioral therapy for 20 weekly sessions. The results from this study were as follows. The average age of the subjects was 11.3 years, mean height and weight were 146.12cm and 59.42kg respectively. After weight control preogram, Rohrer index(Rl) was significantly decreased from 186.78 to 182.72(p<0.001). There were not significant differences in body fat percent(%) and fat weight(kg) but it showed decreased pattern. In the change of body circumferences, chest circumference was significantly increased(p<0.01) and mid-arm circumference was significantly decreased(p<0.001) after weight control program. Triglyceride(TG) level in serum was significantly decreased from 113.79 to 80.36(p<0.01) and total cholesterol and LDL-cholesterol level showed declind pattern. The food habits of obese children significantly improved(p<0.001) after weight control prgram. And there were desirable changes of food attitude, excercise and life habits. These results suggest that weight control program including nutrition education, exercise and behavioral therapy may be effective for helping obese children.

Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease. Mesalizine for the first-line therapy of UC has adverse effects include pancreatitis, pneumonia and pericarditis. UC complicated by two coexisting conditions, however, is very rare. Moreover, drug-related pulmonary toxicity is particularly rare. An 11-year-old male patient was hospitalized for recurring upper abdominal pain after meals with vomiting, hematochezia and exertional dyspnea developing at 2 weeks of mesalizine therapy for UC. The serum level of lipase was elevated. Chest X-ray and thorax computed tomography showed interstitial pneumonitis. Mesalizine was discontinued and steroid therapy was initiated. Five days after admission, symptoms were resolved and mesalizine was resumed after a drop in amylase and lipase level. Symptoms returned the following day, however, accompanied by increased the serum levels of amylase and lipase. Mesalizine was discontinued again and recurring symptoms rapidly improved.

The purpose of this study was to investigate the dietary behavior of people with type 2 diabetes mellitus and to improve their quality of life through medical nutrition therapy. The subjects were 38 persons with type 2 diabetes mellitus visiting a public health center to participate in a dietary education program from Jun, 2003 to Nov. 2003 in Daegu, Korea. The interviews were tape-recorded and analyzed attitude, knowledge, and awareness of patients by focus group interview. Most of the patients were mainly dependent on drug therapy and had little experience of diet education. Barriers to dietary practice adherences were limitations in food selection, lack of will and feel of burden. Barriers to follow guidelines were lack of self-control, confliction with food habits of their family, accessibility, economical problems, fear for the change after dietary practice, food difficulties in meal distribution and difficulties for eating out. After 4 weeks of intensive nutrition education, fasting blood sugar levels were decreased and postprandial and waist circumference were significantly decreased in all patients and 26.9% of patients were under decreased oral hypoglycemic agent dosage due to improved blood sugar level. dietary knowledge of subjects were greatly improved in such items as dietary intake, saturated fat, HbA1C, ideal body weight, and waist circumference.

Objectives: The nutritional status of cancer patients undergoing chemotherapy is closely related to the compliance of nutrition education. However, as chemotherapy is conducted repeatedly, compliance with nutrition management is lowered, leading to malnutrition. Malnutrition is related directly to the quality of life after surgery in cancer patients. Therefore, this study examined the factors related to compliance with nutrition management during chemotherapy. Methods: In this study, five subjects with colorectal cancer undergoing adjuvant chemotherapy were interviewed in-depth using the Giorgi study method. The contents of the nutrition education visits and in-depth interviews were transcribed in the language of the subject after recording, and the appropriateness of the data was improved by reflecting the subject's actions and facial expressions. Results: After conducting the in-depth interviews for each subject, the experience of the subject's diet and adjuvant chemotherapy was drawn into two domains, six elements, and 26 sub-elements. In the cognitive domain, the patients experienced physical and psychological changes, and the need for nutrition management was recognized by analyzing the dietary causes of the diseases. In the domain of practice, a knowing-doing gap was formed, unlike the patient's will. Factors that inhibited compliance with nutritional management included digestive problems, sensory changes, loss of appetite, and social interaction stress. Conclusions: Dietary management is very important for patients receiving periodic anticancer therapy, and step-by-step training and personal monitoring based on the chemotherapy order is necessary to maintain the patient's will and social and environmental support.

This study was conducted to investigate the effectiveness of nutrition counseling on the dietary intake and nutritional status cancer patients undergoing radiotherapy treatment. The study was conducted over 6 week period and included 104 patients : 66 received nutrition counseling as the variable group of 42 male and 24 female and 38 patients received no counseling as the control group of 19 male and 19 female. Nutrition counseling was accompanied with the radiation therapy and adminstered via counseling session and distribution of printed material during radiation therapy for 6 weeks. Nutrition counseling aimed at maintaining a balanced diet and preventing weight loss of subjects, guideline used for energy and protein intake were 35kcal/kg IBW and 1.5-2.0g/kg IBW, respectively. Over the course of the study, the counseling group increased significantly in comparison to the control group's energy intake, evidenced by the counseling group's initial mean daily energy intake of 1932.0kcal, and 4 and 6 week mean energy intake values of 2046.6kcal, 2066kcal, respectively. But mean energy values of control group was 1614.3kcal at 4 week. Th energy intake per weight values and protein intake per weight values for initial, 4 and 6 week intervals for counseling group were 33.2kcal/kg, 33.7kcal/kg, 34.0kcal/kg, and 1.48g/kg, 1.58g/kg, 1.59g/kg, respectively. Based on results, nutrition counseling had positive effects on both the variety of diet and energy intake of the variable group, mostly due to an increase in dairy product and egg consumption. In addition, the percentage of counseling group patients who consumed all 5 food group increased from 48.5% to 54.5%. Sufficient energy intake and protein consumption seem to be important factors in weight loss prevention, evidenced by weight gain by subjects in the counseling group who had 36.1kcal/kg/day mean energy intake and 1.77g/kg/day mean protein intake after 4 weeks. Counseling group subjects experiencing weight loss had lower intake and 1.77g/kg/day mean protein intake after 3 weeks. Counseling group subjects experiencing weight loss had lower intakes of 29.3kcal/kg/day for energy and 1.33g/kg/day for protein during the same period. Another significant factor in weight loss prevention of the counseling group could be the variety of diet. The dietary variety scores(DVS) of both counseling and control groups differed significantly : the counseling group had a mean score of 34 while the control group of patients. At the end of the study, the mean percentage of subjects within each group having a DDS 5 was higher in the counseling group (54.5% v.s. 24.0%). In this study, nutrition counseling for cancer patients undergoing radiation therapy proved to be effective in preventing weight loss, a major complication during radiotherapy. Nutrition counseling not only increased protein and energy intake, but also had desirable effects on variety or diversity of diet.

The purpose of this study was to investigate the effect of medical nutrition therapy (MNT) on anthropometric measurements, quality of diets, and blood parameters through the weight loss program in over weight or obese women. The subjects (n=76, $age\;31.1{\pm}8.4y,\;weight\;70.3{\pm}7.9kg,\;BMI\;27.2{\pm}2.4kg/m^2$) without medical disease were treated with MNT 5 times for 12 weeks by dietitian. Anthropometric measurements included height, weight, fat mass, lean body mass, triceps and thigh skin-fold thickness, mid-arm, waist, hip and thigh circumference. Dietary assessments were accomplished using 3-days food records, diet quality index (DQI), and dietary pattern. The dietary pattern was assessed by daily energy intakes from breakfast, lunch, dinner, and snacks of calorie density, and numbers of eating. Blood levels of leptin, lipid profiles (total lipids, total cholesterol, LDL-cholesterol, HDL-cholesterol), and insulin were analyzed. Anthropometric measurements decreased significantly after MNT (p<0.001). Waist circumference was reduced most rapidly and tricep skin-fold thickness was reduced most effectively after 12 weeks of MNT. Daily energy intake, calorie density and numbers of eating incidence decreased significantly $0796.4{\pm}395.5\;vs\;1402.9{\pm}217.8\;kcal/day,\;162.3{\pm}56.5\;vs\;113.4{\pm}30.1,\;5.0{\pm}1.4\;vs\;3.8{\pm}0.4$, respectively, p<0.05). The daily energy intake from breakfast and snacks significantly decreased (p<0.001). Calories from snack, calorie density of snack and numbers of snacking also decreased (p<0.05). The mean scores of DQI significantly increased ($7.6{\pm}2.1\;vs\;6.5{\pm}1.6$, p<0.05). The plasma levels of total lipid, triglyceride (TG), total cholesterol, LDL-cholesterol and leptin decreased significantly after MNT ($489.8{\pm}100.4\;vs\;447.0{\pm}87.3mg/dL,\;187.7{\pm}34.0\;vs\;175.9{\pm}31.5mg/dL,\;115.2{\pm}29.2\;vs\;109.2{\pm}26.7mg/dL,\;15.7{\pm}7.6\;vs\;12.4{\pm}5.9ng/mL$, respectively, p<0.05). These results indicate that MNT efficiently reduced the body weight through the changes in dietary intake, dietary patterns and dietary quality. MNT also changed body composition and reduced the levels of plasma lipid, cholesterol and leptin.

Purpose: The efficacy of exclusive enteral nutrition (EEN) with a polymeric diet has not been confirmed in Korean pediatric patients with Crohn's disease (CD). This study aimed to compare the effectiveness of EEN with a specific polymeric diet ($Encover^{(R)}$) and corticosteroids (CSs) for the induction of remission in Korean pediatric CD patients. Methods: We retrospectively compared data from 51 pediatric CD patients who underwent induction therapy with EEN (n=19) or CSs (n=32) at Severance Children's Hospital or Incheon St. Mary's Hospital in Korea. The primary endpoint of this study was the rate of clinical remission, defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score <10, after 8 weeks of induction treatment. Clinical, laboratory, and growth data at post-induction as well as their changes from baseline were also compared between groups. Results: After 8 weeks of induction therapy, clinical remission rates were 78.9% (15/19) and 65.6% (21/32) in the EEN and CS groups, respectively (p=0.313). No significant differences in PCDAI scores, laboratory variables, and growth parameters were noted between the two groups at post-induction. However, significant changes in albumin levels at post-induction were observed in the EEN group compared to the CS group (p=0.038). Conclusion: Our results suggest that the effectiveness of EEN with a polymeric diet and CSs for induction therapy did not differ in Korean pediatric CD patients. EEN with a polymeric diet is a good first-line treatment option for the induction of remission in these patients.

BACKGROUND/OBJECTIVES: Despite the importance of a low-iodine diet (LID) for thyroid cancer patients preparing for radioactive iodine (RAI) therapy, few studies have evaluated dietary intake during LID. This study evaluated the amount of dietary iodine intake and its major food sources during a typical diet and during LID periods for thyroid cancer patients preparing for RAI therapy, and examined how the type of nutrition education of LID affects iodine intake. SUBJECTS/METHODS: A total of 92 differentiated thyroid cancer patients with total thyroidectomy were enrolled from Seoul National University Hospital. All subjects completed three days of dietary records during usual and low-iodine diets before $^{131}I$ administration. RESULTS: The median iodine intake was $290{\mu}g/day$ on the usual diet and $63.2{\mu}g/day$ on the LID. The major food groups during the usual diet were seaweed, salted vegetables, fish, milk, and dairy products and the consumption of these foods decreased significantly during LID. The mean energy intake on the LID was 1,325 kcal, which was 446 kcal lower than on the usual diet (1,771 kcal). By avoiding iodine, the intake of most other nutrients, including sodium, was significantly reduced during LID (P < 0.005). Regarding nutritional education, intensive education was more effective than a simple education at reducing iodine intake. CONCLUSION: Iodine intake for thyroid cancer patients was significantly reduced during LID and was within the recommended amount. However, the intake of most other nutrients and calories was also reduced. Future studies are needed to develop a practical dietary protocol for a LID in Korean patients.
