The aim of this study was to investigate the changes of nutritional intake and nutritional status and analyze the association between them during hematopoietic stem cell transplantation. This was a retrospective cross sectional study on 36 patients (9 Autologous transplantation group and 27 Allogeneic transplantation group) undergoing hematopoietic stem cell transplantation at The Catholic University of Korea, Seoul St. Mary's Hospital from May to August 2010. To assess oral intake and parenteral nutrition intake, 24-hour recall method and patient's charts review was performed. Nutritional status was measured with the scored patient-generated subjective global assessment (PG-SGA). The subjects consisted of 6 (66.7%) males and 3 (33.3%) females in the autologous transplantation group (auto), 12 (44.4%) males and 15 (55.6%) females in the allogeneic transplantation group (allo). The mean age was 40.9 ± 13.6 years (auto) and 37.8 ± 11.0 years (allo). The average hospitalized period was 25.2 ± 3.5 days (auto) and 31.6 ± 6.6 days (allo), which were significant different (p < 0.05). Nutritional intake was lowest at Post+1wk in two groups. In addition, calorie intake by oral diet to recommended intake at Post+2wk was low (20.8% auto and 20.5% allo) but there were no significant differences in change of nutritional intake over time (Admission, Pre-1day, Post+1wk, Post+2wk) between auto group and allo group by repeated measures ANOVA test. The result of nutritional assessment through PG-SGA was significantly different at Pre-1day only (p < 0.01). There was a significant negative correlation between the nutritional status during Post+2wk and the oral calorie/protein intake to recommended amount measured during Post+1wk and Post+2wk (p < 0.01). These results could be used to establish evidence-based nutritional care guidelines for patients during hematopoietic stem cell transplantation.

The purposes of the study were to assess knowledge, self-efficacy, and perceived barriers on a low-iodine diet among thyroid cancer patients and to identify strategies for nutrition education. A self-administered questionnaire was developed based on a review of literature and pilot-tested. A total of 121 female thyroid cancer patients participated in a survey and 117 responses were used for data analysis. An average knowledge score of the thyroid cancer patients was 4.5 point (available score: 0-10 point). Majority of the respondents knew that seaweeds such as lavers, brown seaweeds, and sea tangles contain large amount of iodine. However they mistook the low iodine diet as a low salt diet and were not aware of foods and seasonings that are allowed on the low iodine diet. While self-efficacy related to consuming various fruits and vegetables, to choosing potatoes and sweet potatoes for snacks, and restricting consumption of eggs, milk and milk products, and processed foods was rated highly, self-efficacy for preparing foods without using sea salts was rated low. The self-efficacy score increased as their interest on the dietary life and perceived cooking skills were greater. Most perceived barriers toward practicing the low iodine diet were related to preparation of the low iodine menus. As their interest in the dietary life and cooking and perceived cooking skills were greater, the patients perceived barriers on practicing the low iodine diet less. While the patients showed higher self-efficacy and lower barrier perception on selecting foods low in iodine and restricting food high in iodine, they showed lower self-efficacy and higher barrier perceptions on preparing low iodine meals. Clinical dietitians should recognize the gap between what the patients should know and what they really know and identify strategies on how to improve self-efficacy and reduce perceived barriers on the low iodine diet. Recent literature and the findings of the study reveal that incorporating cooking classes into nutrition education for thyroid patients is effective to enhance self-efficacy and to reduce perceived barriers on the low iodine diet.

This study compared birth stature, parents' stature, and food and nutrient intakes between normal and short stature Korean children visiting a growth clinic. A total of 143 growth clinic visitors agreed to participate in the study. Out of the 143 subjects, 37 children with height below the fifth percentile (short stature group) and 58 children with height above the twenty-fifth percentile (normal group) were included in the study analysis. Data were collected through a survey of parents or guardians of children and anthropometric measurements. The ratio of short stature in either parent was significantly higher in short stature group. The mean intakes of protein, fat, calcium, and iron were lower in short stature children compared to normal children. Among five major food groups, the intake frequency of vegetables and fruits was significantly lower in short stature group and that of meat·fish·egg·legume group was also significantly lower in short stature group. In further analysis categorized into 11 detail food groups, the intake frequency of fruit group and legume group was significantly lower in short stature group. Nutritional counseling should be provided to emphasize adequate intake of various food groups including vegetables, fruits, and legumes to short stature children visiting a growth clinic.

Manganese (Mn) is an essential micronutrient for human and plays an important role as a cofactor for several enzymes involving fatty acid synthesis, hepatic gluconeogenesis, and oxidative stresses. Also, Mn intake status has been reported to have beneficial effects in reversing metabolic dysfunction including obesity and nonalcoholic steatosis which is linked to mitochondrial dysfunction and oxidative stresses, however, information on dietary Mn intake in Koreans are limited. Hence we investigated the relationship between dietary Mn intake and antioxidant defense factors in healthy and obese subjects. Total of 333 healthy subjects were recruited in the study and were assigned to one of three study groups: a normal group (18.5-22.9), a overweight group (23-24.9), and a obesity group (>25) according to their body mass index (BMI). We assessed Mn intakes (24-hr recall method) and several indicators for antioxidative defenses such as glutathione (GSH), glutathione peroxidase (GPx) and urinary malonaldehyde (MDA). Results showed that body weight and blood pressure of study subjects were increased in dependent of their BMI (p < 0.01). However dietary Mn intakes and oxidative stress biomarkers (GSH, GPx, and MDA) were not significantly different by groups defined by BMI. In correlation analysis adjusting for age, sex and energy intake, dietary Mn intake of the subjects in different BMI categories were not significantly correlated with GSH, GPx, MDA and showed a weak or no association with these oxidative stress markers. In conclusion dietary Mn intake at least in this study has a little or no influence on markers of oxidative status in both healthy and obese subjects.

The purpose of this study was to describe the pattern of "health functional food (HFF)" intake and related factors in Busan and Gyeongnam area and provide useful information for health promotion through the use of HFF. Among subjects of this study (n = 634), about 64% of the subjects reported that they are currently taking HFFs or other health foods or had HFFs in the last year. The reason of subjects taking HFF was to maintain and promote their health. They choose HFF by their own judgement or knowledge and the main place of purchasing HFF was the HFF store. Main food sources for promoting health in study subjects were nutrient fortified foods (76.8%), fruit or vegetable extracts (64.8%), HFF (64%), herbs or oriental medicines (29.6%), folk remedies or unidentified remedies (24.9%), respectively. The preference type of the products was capsule and liquid. 60.6% of consumers thought that HFF are expensive. 9.7% of consumers experienced the side effect such as stomachache and gastroenteric trouble. Using logistic regression analysis, the use of HFF was 1.9 times higher in female than male subjects indicating strong association between gender and HFF use. Additionally higher prevalence was found in female subjects for right conception of HFF and distinction of HFF. Interestingly subjects who consume less salts exhibited a higher tendency (-1.5 folds) in HFF intake than who prefer to use salt and seasonings in diets. In total study subjects 83.9% of them have known and heard about definition of the HFF. The major route of acquiring the information about HFF was mass media such as TV, internet and newspapers. Also subjects who had taken HFF exhibited high a proper conception toward the knowledge about 'distinction of HFF'. Taken together education programs considering gender, dietary habit and life style is necessary for consumers to select proper HFF.

The purpose of this study was to investigate effect of nutrition education at worksite program in male workers. The subjects were 75 male workers who had received nutrition education by a clinical dietitian for 4 months. The anthropometric data, blood pressure and biochemical blood indices were measured before and after nutrition education. Dietary habits and lifestyle were investigated by self-administered questionnaires. Nutrients intake was determined by 24-hour dietary recall method. The results showed significant decreases in body mass index (p < 0.05), fasting blood sugar (p < 0.01), total cholesterol (p < 0.05), and LDL-cholesterol (p < 0.05) after nutrition education. The correlation analyses among anthropometric and clinical parameters after nutrition education indicated that there was a significantly positive correlations between blood pressure and weight, r-GTP. A significantly positive correlations was observed between fasting blood sugar and triglycerides. A significantly positive correlations was observed between triglycerides and body mass index, r-GTP, SGPT. A significantly positive correlations was observed between SGPT and weight, body mass index. A significantly negative correlations was observed between HDL-cholesterol and weight. It could be concluded that nutrition education might be effective tool to improve anthropometric measures and clinical parameters in male workers. Continuing and systematic nutritional management programs should be developed and implemented for male workers at the worksites to maintain optimal health status.

Understanding the relationship between energy nutrients compositions in a diet and appetite-controlling substances is essential for providing sound advice to anyone attempting to control body weight. Appetite is known to be affected by various hormones, ghrelin and peptide tyrosine-tyrosine (PYY), which are related to the compositions of a diet. The purpose of this study was to investigate the effects of compositions of energy nutrients in the diet on the levels of postprandial appetite-related hormones and satiety in healthy adult women. Ten subjects (BMI: 18.5-22.9 kg/m2) were recruited and assigned to three iso-coloric breakfast meals with different compositions of energy nutrients, regular meal (RM, CHO: 60%, Pro: 20%, Fat: 20%), high protein meal (HPM, CHO: 30%, Pro: 50%, Fat: 20%), and high fat meal (HFM, CHO: 30%, Pro: 20%, Fat: 50%). Blood levels of ghrelin, PYY, insulin and leptin and satiety were assessed at baseline, 30, 60, 90, 120, and 180 min following the consumption of each meal. There was no significant difference in the fasting blood hormones among the subjects taking each meals at baseline. Blood levels of ghrelin and insulin changed significantly following the consumption of each meal (p<0.05) over time, however no significant difference was shown between experimental meals until 180 min. Blood levels of PYY and leptin were not changed following the ingestion of each meals. In conclusion, the composition of energy nutrients in a diet had no effect on the postprandial plasma levels of ghrelin, PYY, insulin and leptin as well as satiety in healthy adult women.

The purpose of this study was to analyze the accuracy of predictive equations for resting metabolic rate (RMR) and daily energy expenditure in policemen on a rotating shift. Subjects were 28 healthy policemen on a rotating shift (males) age of 23-46 years. The participants' RMR was measured by using indirect calorimetry (TrueOne2400) and also calculated from various predicted equations of RMR (Harris-Benedict, Schofield(W)/(WH), FAO/WHO/UNU(W)/(W/H), Cunningham, Mifflin, Liu, Owen, IMNA and Henry(W)/(WH)). The accuracy of these equations were evaluated on basis of accurate prediction (the percentage of subjects whose RMR was predicted within 90% to 110% of the RMR measured), mean difference, root mean squared prediction error, mean % difference, limits of agreement of Bland-Altman method between predicted and measured RMR. The measured RMR value of subjects was 1748 ± 205.9 kcal. Of the predictive equations tested, the Harris-Benedict equation (mean difference: -14.8 kcal/day, RMSPE: 195.8 kcal/day, mean % difference: 0.1%) was the most accurate and precise, but accuracy in prediction of the equation were only 35.7%. The daily energy expenditure at night-duty was 3062 kcal calculated as multiplying RMR by its physical activity level. Subsequently, daily energy expenditure of day-duty was 2647 kcal and the lowest daily energy expenditure was, 2310 kcal at holiday duty. Daily energy intake of all study participants was 2351 kcal at day-duty, 1959 kcal at night-duty and 1796 kcal at holiday-duty in order. The estimated energy requirements for policemen on a rotating shift on day shift, night shift and holiday came to 2743.6 kcal/day, 2998.6 kcal/day and 2576.9 kcal/day, respectively. These results suggest that estimated energy requirements (EER) of policemen on a rotating shift should be differently proposed by a proper equation which can closely reflect their metabolic status at each time shift.

Adequate amounts of nutrients during pregnancy are essential for maternal, fetal and child health. This study was conducted to investigate the intakes of iron and folate and the effect of supplements on anemia status during pregnancy. One hundred sixty five pregnant women completed questionnaires which included food frequencies and supplement use, and blood tests for hematologic indices. Pregnant women were divided into four groups based on the type of supplements; single nutrient group (S), multivitamins & minerals group (M), Single nutrient + multivitamins & minerals group (S+M), and no supplement group (N). Mean iron intake was 11.1 mg from food (46.3% of Recommended Nutrient Intakes, RNIs) and 66.8 mg from supplements. Mean folate intake was 231.2 µg from food (38.5% of RNI) and 822.7 µg from supplements. In the N group, the subjects who consumed iron and folate less than EAR were 85.7% and 95.2%, respectively. The subjects consumed iron more than UL were 81.0% in the S group, 88.9% in the M group, and 97.4% in the S+M group, and the subjects consumed folate more than UL were 4.8% in the S group, 1.6% in the M group, and 25.6% in the S+M group. The mean values of hemoglobin and hemotocrit in the M group were significantly higher than those in the N group. Despite the relatively high socio-economic status of the participants, overall intakes of iron and folate from food were far below the RNIs, suggesting that a supplement is needed for adequate nutritional status during pregnancy. A multivitamin supplement seems to be more effective than a single nutrient supplement such as iron or folic acid in the prevention of anemia. Further research is required to define the appropriate amount of supplemental iron and folic acid for Korean pregnant women.

High sugar intake has been suggested to be related to hypertension. To examine the associations between intakes of sugar and sugar-sweetened beverages (SSBs) and the prevalence of hypertension, we used the US National Health and Nutrition Examination Survey (NHANES) 2003-2006. A total of 3,044 participants aged ≥19 years were included. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) using multivariate logistic regression model. Prevalent hypertension cases were defined as systolic blood pressure (SBP) of ≥140 mmHg or diastolic blood pressure (DBP) of ≥90 mmHg. In the multivariate adjusted models, we observed no association between sugar consumption and the prevalence of hypertension. In the model where we adjusted for age, gender, NHANES period and BMI, those who consumed ≥3 times per day of sugar-sweetened beverages had an OR of 1.87 (95% confidence interval, CI = 1.06-3.26) for the prevalence of hypertension compared with those who consumed <1 time per month of these beverages. Further adjustment for other factors attenuated the association; ORs (95% CIs) were 1.21 (0.81-1.81) for 1 time per month-<3 times per week, 1.39 (0.86-2.24) for 3 times per week-<1 times per day, 1.26 (0.80-1.98) for 1-<3 times per day, and 1.50 (0.84-2.68) for ≥3 times per day of sugar-sweetened beverages compared to the <1 time per month (p for trend = 0.33). In conclusion, we found that sugar consumption was not associated with the prevalence of hypertension, however there was suggestion that high sugar-sweetened beverage consumption was associated with high prevalence of hypertension in the US.

The
objective
of this article is to report improvement of nutritional status by protein supplements in the patient with protein-losing enteropathy. The patient was a female whose age was 25 and underwent medical treatment of Crohn's disease, an inflammatory bowl disease, after diagnosis of cryptogenic multifocal ulcerous enteritis. The weight was 33.3 kg (68% of IBW) in the severe underweight and suffered from ascites and subcutaneous edema with hypoalbuminemia (1.3 g/dL) at the time of hospitalization. The patient consumed food restrictively due to abdominal discomfort. Despite various attempts of oral feeding, the levels of calorie and protein intake fell into 40-50% of the required amount, which was 800-900 kcal/d (24-27 kcal/kg/d) for calorie and 34 g/d (1 g/kg/d) for protein. It was planned to supplement the patient with caloric supplementation (40-50 kcal/kg) and protein supplementation (2.5 g/kg) to increase body weight and improve hypoproteinemia. It was also planned to increase the level of protein intake slowly to target 55 g/d in about 2 weeks starting from 10 g/d and monitored kidney load with high protein supplementation. The weight loss was 1.0 kg when the patient was discharged from the hospital (hospitalization periods of 4 weeks), however, serum albumin was improved from 1.3 g/dL to 2.5 g/dL and there was no abdominal discomfort. She kept supplement of protein at 55 g/d for 5 months after the discharge from the hospital and kept it at 35 g/d for about 2 months and then 25 g/d. The body weight increased gradually from 32.3 kg (65% of IBW) to 44.0 kg (89% of IBW) by 36% for the period of F/u and serum albumin was kept above 2.8 g/dL without intravenous injection of albumin. The performance status was improved from 4 points of 'very tired' to 2 points of 'a little tired' out of 5-point scale measurement and the use of diuretic stopped from the time of 4th month after the discharge from the hospital owing to improvement in edema and ascites. During this period, the results of blood test such as BUN, Cr, and electrolytes were within the normal range. In conclusion, hypoproteinemia
and weight loss were improved by increasing protein intake through utilization of protein supplements in protein-losing enteropathy.
