The present study was to investigate the nutritional status and factors related to malnutrition in end-stage renal disease (ESRD) patients requiring hemodialysis (HD) in South Korea. Subjects were ESRD outpatients from general hospitals or HD centers in Seoul referred to the dialysis clinic for maintenance HD care. A total of 110 patients (46 men and 64 women; mean ages $58.6{\pm}1.0y$) were eligible for this study. The family history of chronic renal failure (CRF) was considered positive if a patient reported having either a first-degree or second-degree relative with CRF. Malnutrition was defined as a triceps skinfold thickness or mid-ann muscle circumference below the fifth percentile for age and sex and forty-seven of the 110 patients were malnourished. Almost all (94%) patients had anemia (hemoglobin: <13 g/dL for men and <12 g/dL for women). Energy intake was below the recommended intake levels of energy [30-35 kcal/kg ideal body weight (IBW)] and protein (1.2 g/kg IBW) in 60% of patients. The duration of HD was longer in malnourished HD patients (P=0.0095). Malnutrition was more prevalent in women (P=0.0014), those who never smoked (P=0.0007), nondiabetic patients (P=0.0113), and patients with bone diseases (P=0.0427), adequate HD (spKt/$V{\geq}1.2$) (P=0.0178), and those with a family history of CRF (P=0.0255). Multiple logistic regression was used to examine the relationship between malnutrition and potential risk factors. After adjusting for age, sex, and other putative risk factors for malnutrition, the OR for malnutrition was greater in HD patients with a family history of CRF (OR, 3.290; 95% CI, $1.003{sim}10.793$). Active nutrition monitoring is needed to improve the nutritional status of HD patients. A family history of CRF may be an independent risk factor for malnutrition in Korean HD patients. A follow-up study is needed to investigate whether there is a causal relationship between a family history of CRF and malnutrition in Korean ESRD patients.

The purpose of this study was to analyze the effects after having the obesity education with obese elementary school children. The subjects were made up of 31 obese children out of U elementary school in B town as experimental group, and also were selected 34 children out of S elementary school under the same circumstance as control group. They ranged from the third to sixth grades with over 30% body fat ratio. The proceeding of obesity education consisted of three stage; stage for preparation, stage for practice, and stage for finish. The stages mentioned above were put into practice in turn for eleven weeks beginning on Oct. 8, 2001 through Dec. 22, 2001, while two stages only, stage for preparation and finish, were put into practice on the control group. The contents of the education for eleven weeks obesity regulation contained counseling and taking regular exercises once a week by professional gym teacher. In order to evaluate the effects of the education, physical characteristics, body composition, physical fitness, knowledge of obesity, dietry habit and attitude were measured. The obtained data were analyzed using SPSS program, the effects of pre and post obesity education in experimintal group were measured by paired-t test. The conclusions of this study were as follows : 1. Body fat ratio was significantly reduced after obesity education in experimintal group(p=.003). 2. The height with experimental group got taller remarkably(p=.000), but weight showed no signeficance after obesity education(p=.258). 3. Triceps and subscapular skinfold thickness showed remarkable decrese after obesity education(p=.000), percentage body fat and body fat amount got down remarkably after obesity education(p=.000). Percentage lean body mass and lean body mass amount got down remarkably after obesity education(p=.000). 4. Body flexibility, agility and muscle endurance graded up remarkably after obesity education(p=.009, p=.000, p=.000). 5. The grade in obesity knowledge got up remarkably after obesity education(p.000), but dietry habits and its life showed no significance in figures after obesity education(p=.335, p=.112). Through the results shown above, the obesity education caused body fat ratio, physique, body composition to grade up and physical fitness elevated, while dietry habits and its life showed no significance.

Long-term hemodialysis(HD) patients manifest various signs of protein and caloric malutrition due to poor intake of nutrients and other causes. Poor nutritional status increases the mortality and morbidity rates in HD patients. Thus, mataintnance of adequate nutritional status has been a major task in taking care of patients receiving HD. This study was to evaluate the nutritional status of HD patients and to clarify the degree of nutritional deficit based on usual dietary intake, anthropometric and biochemical indicators. Sixty HD patients comprised a HD group, while the control group consisted of 60 healthy adults whose age and sex matched those of the HD group. Nutritional status was evaluated by dietrary intake using instant nutritional scale, anthropometric measures, serum protein concentrations and the number of lymphocytes. The data were analyzed by using Chi-square test and unpaired t-test. The results are as follows. 1. Regarding usual dietary intake of HD group. 1) Estimated caloric intake was significantly lower than the recommended daily allowance(RDA) and among them, 35% were taking calories less than 85% of the RDA. 2) Estimated protein intake was significantly higher than the RDA and among them 40% were taking protein more than 115% of the RDA. 3) Estimated fat intake was lower than the RDA. 4) Vitamin A, B, $B_1,\;B_2$, C and niacin in take was lower than the RDA respectively. 5) Estimated ferrous intake was within the normal limit the RDA while estimated calcium intake was higher than the RDA. 6) Both calorie and protein intake were higher for the 10 patients who had been under continuous ambulatory peritoneal dialysis than for the patients under HD from the beginning. 2. Regarding anthropometric measures : 1) Body mass index(BMI), midarm circumference(MAC), and triceps skinfold thickness(TSF) were lower in the HD group than in the control group. 2) Among HD group, 47.1% were within the normal limit of BMI, while 86.7% were within the same limit in the control group. 3) Among HD group, 35.0% were within the normal limit of MAC, while 83.3% were within the same limit in the control group. 4) Among HD group, only 8.3% were normal, 30.3% were mild deficit status of TSF, while 50% were normal and 48.3% were mild deficit status in the control group. 3. Regarding biochemical laboratory tests 1) Albumin, transferrin concentrations and the number of lymphocytes were lower in HD group than in the control group. 2) Among HD group, 98.3% were within the normal limit of albumin concentration and all were within the same limit in the control group. 3) Among HD group, only 11.7% were within the normal limit of transferrin concentration, while 81.7% were within the same limit in the control group. 4) Among HD group, 25% were within the normal limit, while 93.3% were within the same limit in the control group. The above findings suggest that HD patients were in nutritional deficit status. Adequate diet therapy and periodical evaluation of the nutritional status in HD patients are needed. Accordingly, it turned out that anthropometric measures were very reliable parameters and easy to use to evaluate nutritional status. So nurses are encouraged to adopt anthropometric measures to examine nutritional deficit status of HD patients.

The purpose of this study was to investigate the obesity and state of dietary intake of 216 young Korean females, and the influence of $\beta$-II, III Adrenergic receptor (AR) gene polymorphism upon obesity and dietary intake. The average weight, height and BMI of the subjects were 160 cm, 54 kg, and 20.9 kg/$m^2$, respectively. The average triceps skinfold thickness, waist circumference, hip circumference and WHR were 21.7mm, 73.1cm, 93.3cm and 0.78, respectively. The results of body composition measurement using bioimpedance method, average body fluid, body protein, mineral mass and body fat were 29.271, 7.22 kg, 6.79 kg and 19.16 kg, respectively. A dietary survey was conducted using 24-hour recall method. Average calorie intake was 1621 ㎉, which is 81% of Korean RDA. We detected 182 (84.3%) Gln27 (QQ) homozygotes and 34 (15.7%) Gln27Glu (QE) heterozygotes for $\beta$-II AR polymorphism. For $\beta$-III AR polymorphism, we detected 163 (75.5%) Trp64 (WW) and 53 (24.5%) Trp 64Arg (WR). The results of comparing of obesity by $\beta$-II AR gene polymorphism, obesity index and BMI of QE type were slightly higher than those of the QQ type. For $\beta$-III AR gene polymorphism, the mean BMI, obesity index, fat mass and percent body fat (%) of the WR type were significantly higher than those of the WW type (p < 0.05). These findings suggest that genetic variability in the human $\beta$-III AR is associated with obesity among young Korean females. We also evaluated the effect of the simultaneous presence of the $\beta$-II AR and $\beta$-III AR polymorphism on obesity. We found that the BMI and obesity index of the mutant type in both $\beta$-II AR and $\beta$-III AR were significantly higher than those of the type that has only one gene mutation or has no mutation (p < 0.05), indicating a synergistic effect of $\beta$-II AR and $\beta$-III AR polymorphism on obesity. No association was found between $\beta$-II Ad or $\beta$-III AR polymorphism and dietary intake.

This study was conducted for 39 patients who are recipients of allogeneic hemopoietic stem cell transplantation at BMT ward of St. Mary's hospital affiliated to Catholic University of Korea from April to September 1999. The subjects were devided into two groups; those who received both TEl and chemo therapy as conditioning regimen (TEl group). and those who used chemo agents as singular conditioning regimen (chemo group). The oral intake status of the two groups were compared through physical assessment and blood chemistry exam of the subjects, and factors influencing their nutritional change and oral intake were explored in each stage of the transplantation (six stages: admission, conditional stage, date of transplantation, one week after transplantation, two weeks after transplantation, and three weeks after transplantation). The prior aim of the study was to provide baseline data to minimize delayed treatment from nutritional deficiency of the subjects. The results were as follows: 1. TBI group was significantly decreased of oral calorie intake in two weeks after transplantation compared to admission and conditioning stage while that of chemo group was significantly decreased on the date of transplantation. 2. TBI group was significantly decreased of protein intake in two weeks after transplantation compared to admission and conditioning stage. In chemo group, protein intake was significantly decreased on the date of transplantation compared to admission. It was remarkable that TBI group showed lesser protein intake than chemo group. 3. Both group were significantly decreased of BMI in one week and three weeks after transplantation compared to admission. TBI group showed significantly higher BMI than chemo group. 4. Both group were significantly decreased of Triceps Skinfold Thickness (TST)on the date of transplantation compared to admission stage. 5. TBI group was significantly decreased of mid-arm muscle circumference (MAMC) in two weeks after transplantation compared to admission, conditioning, date of transplantation. 6. TBI group was significantly decreased of albumin level in two weeks after transplantation compared admission stage. In chemo group, it was significantly decreased on the date of transplantation compared to admission, three weeks after the transplantation. 7. TBI group was significantly decreased of transferrin level in two weeks after transplantation compared admission, conditioning, date of transplantation and one week after transplantation. In chemo group, it was decreased of transferrin level in 3 weeks after transplantation. 8. Oral intake of TEl group was impacted by vomiting before transplantation and gingivitis after transplantation. In chemo group, it was impacted by vomiting before transplantation and by two factors, gingivitis and nausea, after transplantation. The results showed oral calorie intake was not different between the two groups while protein intake was significantly lower in TBI group than chemo group. Oral intake was significantly impacted by vomiting before transplantation in both groups, but affected by oral gingivitis in TBI group and gingivitis and nausea in chemo group after transplantation. This findings present that standardized strategies to manage nutrition and gingivitis more effectively are desperately needed to enhance oral intake and protein intake of patients who receive TBI as conditioning regimen.

The purpose of this study was to investigate the fluid balance of the patients who were either on soft fluid diet or total parenteral nutrition. We studied 19 patients with neurologic disorders and 22 patients with oromaxillary surgery who were admitted to either D university hospital in Choognam or S general hospital in Seoul between May and November 1995. The mean age for the patients who had oromaxillary surgery was 24 years and their average hospital stay was 9 days. The mean age of the patients with neurologic disorders was 54 years and they were bedridden for average of 71 days. For the maxillary bone surgery patients we did not limit the range of their activities in the ward during data collection period. The patients with neurological disorders were bedridden and did not move around the ward. They were all either on soft fluid diet, or total parenteral nutrition. The findings of this study are as follows ; 1) The difference of the triceps skinfold thickness between the baseline and the final measurement was 0.4cm for neurologic patient group and 0.5cm for oromaxillary surgery patient group. The difference was not statistically significant in each group. 2) In the oromaxillary surgery patient group, the daily intake of fluid in the form of pure water, other beverages, fluid diet as well as IV fluid was 4581m1 while urine output was 2979ml. The difference between fluid intake and output was statistically significant, indicating that fluid intake was far more than urine output. In neurologic patient group, the daily intake of fluid including water from fluid diet and IV fluid was 2701m1 whereas urine output was 2253m1 and they were statistically significant. 3) For a more accurate assessment we adjusted the fluid balance based on weight changes during data collection period. In the oromaxillary surgery patient group. the difference between fluid intake and output was 1238m1 after weight changes being adjusted. The difference was statistically significant, suggesting fluid overload in this patient group. In neurologic patient group, the difference between fluid intake and output considering weight changes was 124ml. The difference was not statistically significant, suggesting that the fluid intake and output was well balanced in this patient group.

The study was performed to investigate the effects of whey protein-rich meal substitute added with vitamins, minerals, and lactobacillus powder probiotics on weight loss, body fat, and body composition in 24 female volunteers for 4 weeks. Whey protein-rich meal substitute was consumed with low-fat, high calcium milk (1% fat, 260 mg/200 mL) twice a day. Subjects submitted 3-day diet records and a life-style questionnaire before the study. During the study, subjects were required to turn in a diet record every day and consume the meal substitute formula in the metabolic ward at C university for 4 weeks. Anthropometric measurements were carried out weekly by Inbody 7.0. The dietary intake and anthropometric data were analyzed to compare changes before and after the study by paired t-test with SPSS version 23.0. The subjects were mostly early 20's and either overweight or obese and highly motivated to lose weight. Most of the subjects consumed three meals per day regularly and spent mostly 10~15 minutes for a meal. Their caloric intake was relatively low and decreased from 1,360 kcal at week 0 to 1,100 kcal after 4 weeks. However, total protein intake increased while carbohydrate and fat intakes decreased (p<0.05) after the trial. Nine vitamin intakes after the study improved compared to those before the study (p<0.05). After the study, subjects showed lower body weight (-1.8 kg), body fat (-0.94 kg), percent body fat (-0.86%), as well as waist circumference (-4.52 cm), hip circumference (-0.44 cm), waist hip ratio (-0.05), and triceps skinfold thickness (-2.39 mm) compared to those at week 0 (p<0.05). Muscle mass tended to be less compared to week 0, although there was no significant differences between weeks 0 and 4. In conclusion, diet trial with whey protein-rich meal substitute induced weight loss and positively changed body fat parameters and body composition.

Purpose: The purpose of this cross-sectional study was to assess the nutritional states and investigate the energy intake of tube-fed patients with severe neurodevelopmental disability. Methods: Eighty six tube-fed patients with severe neurodevelopmental disability were studied. Heights were measured by flexible scale segmentally. Nutritional parameters of weight, triceps skinfold thickness and mid-arm circumference were also measured. Total caloric intakes through the tube were calculated. Results: The anthropometric results showed that nutritional states of tube-fed patients with severe neurodevelopmental disability were poor. The mean daily caloric intake was much less than daily energy requirement (mean=45.2% of requirement). The caloric intake was 7.2 kcal/height (cm), 57.0 kcal/weight (kg). Height was more related with caloric intake (r=0.476) than weight (r=0.263). Conclusion: These results provide that tube-fed patients with severe neurodevelopmental disability were growth retarded and their energy intakes were much less than daily energy requirements. The preliminary evidence was that they need adequate nutritional supply.

The aim of the study was to investigate prevalence of obesity among housewives residing in apartments in Taegu city and any relationship of obesity with various factors. Hundred three housewives aged 30-49 years living in apartments (over 30 pyung) were interviewed for socio-economic status, food habit, food intake by a convenient questionnaire, and daily activity by the 24-hour recall. Their weight, height and triceps skinfold thickness were measured. The results were summarized as follows: 1) The percentages of subjects and their spouses with college and higher education were as much as 53.6% and 83.5%, respectively. The commonest family size was four members with two children. 2) The percentages of subjects classified as underweight, normal, overweight, and obesity according to relative body weight(RBW) were 4.9, 44.7, 24.3 and 26.2, respectively. Twenty four percent belonged to obese group according to body mass index(BMI$\geq$25). 3) Food habit score was 12.4 points in average and judged 'good'. The average of daily energy intake was 2247㎉ which corresponded to 112% of RDA and intakes of nutrients except iron exceeded RDA. The means of food habit score and energy intake were not significantly different among 4 groups. 4) Multiple regression analysis was tested to explain a relationship between fatness and various factors. The equation, BMI=25.216+(0.836$\times$family size)-(0.309$\times$education, years)-(0.00503$\times$household work time, minutes), indicates that fatness of housewives was related with family size(+), educational level(-) and household work time(-). These relationships were statistically significant(p<0.001) and R2 (coefficient of determination) was 0.237.
