Nutritional assessment is based on anthropometric, clinical, dietary and biochemical data. There is a lack of studies about the propriety of biochemical indexes for the nutritional assessment in children despite biochemical data in pediatric population are different from them in adult's in many respects. Serum albumin is useful index to evaluate the severity of malnutrition. Hemoglobin and hematocrit tend to decrease in malnutrition on account of defect of iron metabolism and to increase in metabolic syndrome on account of enhancement of erythropoiesis. But, unlike adult, total lymphocyte count is not so useful biochemical indexes in children. We should consider pediatric characteristic when interpret biochemical indexes for nutritional assessment in children, and nutritional status in children should be assessed comprehensively with anthropometric, clinical, dietary and biochemical data.

Purpose: The purpose of this study was to examine and analyze the post operative fasting period of neonates in the intensive care unit (ICU) after receiving open heart surgery in order to provide optimal nutrition support for these neonates. The variables included biochemical nutrition indexes (albumin, total lymphocyte count, total cholesterol) and patient outcomes (duration of mechanical ventilation, ICU stay, hospital stay, infectious complication). Methods: The participants were 124 neonates in ICU after receiving open heart surgery, and the design of this study was to investigate their post operative fasting period retrospectively to analyze the biochemical nutrition indexes and patient outcomes according to post operative fasting period. Results: The results for 4 groups according to post operative fasting period showed that the group with less 48 hours of fasting had the best biochemical nutrition indexes and patient outcomes, followed by the 48-72 hour group, the 72-144 hour group, and the over 144 hour group. Conclusion: The results indicate that for new born babies receiving open heart surgery, the period of fasting after the operation should be minimized and tube feeding should be started as soon as possible.

Iron is the required microelement supporting life and is the main component of hemoglobin. Thus iron has affinity with exercise capacity. Iron metabolism turbulence induced by exercise is one of causes of hematopoietic hypofunction. Results of the experiment showed that long-term treadmill exercise of progressive loading significantly decreased levels of erythrocyte indexes, serum iron, serum ferritin and significantly increased serum transferrin level. Nutrition supplement could significantly retard the variations, and Exercise +Nutrition group have higher levels of erythrocyte indexes, serum iron, serum ferritin and lower level of serum transferrin than Exercise group. The results indicated that nutrition supplement have function of prevent and cure on iron metabolism turbulence induced by exercise, furthermore significantly enhance hemoglobin level in rats.

목 적 : 소아를 대상으로 생화학적 영양지표들이 각각의 체질량지수군 간에서 어떤 차이를 보이는 지 분석하고, 영양상태의 평가로 생화학적 영양지표들이 유용한 것인가를 알아보기 위하여 이 연구를 시행하였다. 방 법 : 2006년 1월부터 2007년 12월까지 강릉 아산병원에 선택적 수술을 받기 위해 내원한 3세 이상 10세 미만의 소아 중 신체계측 자료와 수술 전 혈액검사 자료가 모두 있는 269명을 대상으로 하였다. 체질량지수에 따라 저체중군, 정상체중군, 과체중군, 비만군으로 나누고 각 군 간에 TLC, 혈색소, 적혈구용적, 혈청 알부민, 총콜레스테롤 등과 같은 생화학적 영양지표가 의미있는 차이를 보이는 지를 후향적으로 분석하였다. 결 과 : 모든 체질량지수군 간에서 TLC는 유의한 차이가 없었다. 하지만 혈청 알부민은 저체중군에서 유의하게 감소되어 있었다. 적혈구수, 혈색소, 적혈구용적과 혈청 총콜레스테롤은 과체중군 또는 비만군에서 정상체중군보다 유의한 증가를 보였다. MCH와 MCV는 모든 군에서 유의한 증가가 없어, 과체중군과 비만군의 혈색소 및 적혈구수 등의 증가는 철분대사 보다는 적혈구 조혈기능의 증강 때문으로 생각된다. 남자와 여자에서 유의한 생화학적 영양지표가 서로 다르게 나타났는데 남자에서는 네 체질량군 간에 적혈구수, 혈색소, 적혈구 용적, 혈청 총콜레스테롤이 일부 유의한 차이를 보인 반면 여자에서는 유의한 차이를 보이지 않았고 알부민만 저체중군과 정상체중군 사이에서 유의한 감소를 보였다. 결 론 : 소아를 대상으로 시행한 생화학적 영양지표 중 적혈구수, 혈색소, 적혈구 용적, 혈청 알부민 및 총콜레스테롤은 체질량지수와 연관성이 있었다. 하지만 여자는 저체중군에서 알부민만 유의한 감소를 보였을 뿐 나머지 생화학 영양지표들과의 통계적 유의성은 없었다. 이에 대해 더 많은 연구가 필요할 것으로 생각된다.

Epidemiological evidence of the effects of dietary sodium, calcium, and potassium, and anthropometric indexes on blood pressure is still inconsistent. To investigate the relationship between dietary factors or anthropometric indexes and hypertension risk, we examined the association of systolic and diastolic blood pressure (SBP and DBP) with sodium, calcium, and potassium intakes and anthropometric indexes in 19~49-year-olds using data from Korean National Health and Nutrition Examination Survey (KNHANES) III. Total of 2,761 young and middle aged adults (574 aged 19~29 years and 2,187 aged 30~49 years) were selected from KNHANES III. General information, nutritional status, and anthropometric data were compared between two age groups (19~29 years old and 30~49 years old). The relevance of blood pressure and risk factors such as age, sex, body mass index (BMI), weight, waist circumference, and the intakes of sodium, potassium, and calcium was determined by multiple regression analysis. Multiple regression models showed that waist circumference, weight, and BMI were positively associated with SBP and DBP in both age groups. Sodium and potassium intakes were not associated with either SBP or DBP. Among 30~49-year-olds, calcium was inversely associated with both SBP and DBP (P = 0.012 and 0.010, respectively). Our findings suggest that encouraging calcium consumption and weight control may play an important role in the primary prevention and management of hypertension in early adulthood.

Purpose: This study investigated the effect of bioactive Yeonsan Ogye peptides (YOPs) intake on changes in the hepatic anti-oxidant indexes in male rats. Methods: Sprague-Dawley male rats were divided into 3 groups and given a casein-based AIN-93G diet and distilled water ad libitum without any added YOPs (control), distilled water with 250 mg of YOPs (Y250), or 500 mg of YOPs (Y500) per kg of body weight for 4 weeks. YOP dose was decided as referred to in the referenced study where toxicity did not occur. The hepatic anti-oxidant indexes were determined using a commercial kit. Statistical analysis was performed using SPSS version 23.0 and are expressed as $mean{\pm}standard$ error of mean. Differences among the groups were evaluated by one-way analysis of variance followed by post hoc Duncan's multiple comparisons test. Results: There were no differences in the body weights, weight gain, food intake, food efficiency ratio, or organ weight, including liver, kidney, spleen, thymus, and epididymal fat, among all of the groups. The hepatic nitric oxide (NO) level in the Y500 group was lower than that in the control and Y250 groups, and the hepatic malondialdehyde (MDA) level was lower in the Y500 group than in the Y250 group. The differences in hepatic superoxide dismutase (SOD) and catalase (CAT) activities were not statistically significant between the groups. From these results we speculated that YOPs may have anti-oxidative abilities to regulate NO and MDA production without affecting SOD and CAT activities. Conclusion: YOPs are presumed to act as anti-oxidants in the animal or human body.

The purpose of this study was to compare food habits and nutrient intakes among high school students with different obesity indexes who are residing in Seoul and Kyunggi-do. a total of 533 subjects were assigned to one of the following groups based on BMI : underweight, normal-weight and overweight. Food habits and nutrient intakes were evaluated based on questionnaires and 24hr-dietary record. The results were as follows. There was no significant differences in the general environmental characteristics of subjects with different BMI. However, the father\`s BMI was significantly higher in overweight female students compared to underweight or normal weight subjects. The menarch age was significantly decreased as the obesity increased. The self-satisfaction score for physical type was decreased as the BMI increased. The overweight group skipped dinner more frequently the other groups among male students. There was no significant difference in the scores of nutrition knowledge, nutritional attitude, and self -satisfaction of subjects with different BMI. The nutrient intakes of overweight group were the lowest among the three groups. In conclusion, obesity among female students may be related to family member\`s obesity. Also overweight students tend to have lower self satisfaction for their body image and undesirable food habits. Therefore, proper nutrition education is required to maintain desirable food habits for overweight students.

The correlation between microbiological and sensory quality indexes was investigated for Korean seasoned side dishes stored under chilled conditions, by using both published data and experimental evaluation. Aerobic bacterial counts on the perishable Korean side dishes showed high inverse correlation with sensory quality and could also be regarded as a main cause of sensory quality deterioration. Therefore, monitoring or estimating the microbial growth on these products should be an effective means for estimating and extending their shelf life.

Variables affecting bone heath of growing children were analyzed among forty nine 10-12 year old elementary students in three rural regions of north west Chungnam area. Information on age of the parents, duration of breast feeding and birth weight were collected from the guardians of the participants and nutrient intake and diet quality were assessed by average of three-day food records of participants with the help of dietitians. Bone health status was measured by calceneal broadband ultrasound attenuation (BUA) using quantitative ultrasound (QUS). Results showed that anthropometic indexes and nutrient intake levels were not different between boys and girls. However, iron intake was significantly lower in girls than in boys. Girls after menarche showed lower intake levels for thiamin, riboflavin, pyridoxine and niacin than girls before menarche. z-scores of BMI were lower than -1 and higher than +1 showed shorter breast feeding period than others but the difference was statistically non-significant. Overall, the subjects did not consume enough s of calcium, vitamin C and folic acid. Zinc intake and BMI were the most significant factors affecting BUA by the results of backward elimination in multiple regression models. Phosphorous and beta-carotene intakes showed significant negative relation with BUA. This study showed that children living in the rural area of Chungnam need extra care to keep their health and nutrient intakes especially for the nutrients known to affect growth. Tailored nutrition education needs to be more focused on the improvement of bone health status of children.

The purpose of this study was to investigate the dietary habits and snack consumption behaviors of middle school students with different obesity indexes in the Chungnam area. The survey was carried out using self-questionnaires and included 385 students(119 underweight, 193 normal weight, 66 overweight). The rate of skipping meals was higher for underweight students than overweight students; however, this difference was not statistically significant. The mean time of meal was 10 to 20 minutes and the criteria for choosing to eat a meal were 'hunger' and 'taste' in all groups. More than half of the subjects ate snacks 1 time a day, which were purchased outside. The typical snack time was 'between lunch and dinner'. The criteria of for consuming a meal were 'taste' and 'price' in all groups. In the underweight group, the snack food scores were ice cream(4.4), fruit(4.3), fried chicken(4.1), sports beverage(4.0), fruit juice(4.0), pizza(4.0) and, tteokbokki(3.9). In the normal weight group, the snack food scores were ice cream(4.3), fried chicken(4.2), pizza(4.0), sports beverage(3.9), fruit juice(3.9) and, tteokbokki(3.9) in the overweight group, the snack food scores were ice cream(4.3), fruit(4.3), fried chicken(4.2), yogurt(4.0), sports beverage(4.0), fruit juice(4.0) and, ramen(4.0). In conclusion, the snaking behaviors of the subjects were not significantly different based on their obesity index. However, this study may provide basic information on the snacking behaviors of middle school students, and the findings suggest that nutrition education or counseling can improve snack intake habits and positive behaviors toward healthy adolescents diets.
