The aim of the present study was to evaluate the relations among nutrient intake. self body image and satisfaction, and physical fitness of college students in Taegu. A total of 213 apparently healthy college students living in Taegu were selected for the study. The following anthropometric measurements were made on all participants : weight, height: waist and hip circumferences, and bioimpedence. Using weight and height, the body mass index (kg/$m^2$) was calculated. The 24-hour recall were obtained from subjects. Dietary habits and energy expenditure were examined through questionnaires. Nutrients intake were analyzed by computer aided nutritional analysis program. Variables of Physical fitness were consisted of body fat, muscular strength and endurance, agility. power, flexibility, cardiorespiratory function, physical efficiency index(PEI). Data were analyzed by computer using the SAS 6.12(Statistical Analysis System). The mean heights and weights of these students were similar to those reported for the 50th percentile in a national survey. Nutrient intake of the college students in Taegu was considerably lower than RDA. The male subjects' mean intake of two nutrients, vitamin B$_2$ and calcium, were less than 55% of the RDAs. the female subjects' mean intake of two nutrients, iron and calcium, were less than 55% of the RDAs. A most variables of physical fitness except sit and reach in male students showed a significant higher values than those of female students. There was a significant positive relationship between PEI and the intake of animal protein, fat, Ca. and B$_2$ in male students. Also there was a significant positive relationship between exercise duration of PWC 170 and protein, fat, iron, vitamin A, B$_2$, niacin, and energy intake in female students. The muscular strength showed the significant correlation with weight, height, and waist circumference in male and female students. The cardiorespiratory function and Physical efficiency index showed significantly negative correlation with tricep and subscapular skin thickness in the female students. There were significantly positive correlations between WHR and body efficiency index in male students, and significantly positive correlations between WHR and the cardiorespiratory function in female students. There was no significant level of correlation between the degree of satisfaction of body image and physical efficiency index. However. there was a significant positive correlation between waist circumference (and weight) and physical efficiency index in male and female students and almost all of the surveyed male and female college students wanted less waist circumference or weight even though they were in the criteria of standard waist circumference or weight. In conclusion, a beneficial effect of adequate nutrient intake on physical fitness was found, college students must increase their energy and nutrient intake if it is below than the RDA for improving their physical fitness.

This study was performed to examine the relationship between the body mass index (BMI), the body fat, and the serum lipids of post-menopausal women in rural areas. The subjects were 510 women aged 50 and over. As a result of this study, we found a trend of decreasing BMI as age increased, but body fat increased. In addition, there was a significant decreasing of the lean body mass than an increasing of the body mass index according to increasing age. Therefore, this study confirmed that a main cause of rural women being classified as obese is a decrease in lean body mass, rather than an increase in of body fat. Of all subjects, 36.3% ($18.5{\leq}BMI$ < 23) of all subjects were classified as having normal BMI, whereas only 21.4% were classified as having normal body fat. Out of 190 subjects who were body fat 30% and over, 38 subjects were classified as obese ($BMI{\geq}25$) and 113 subjects were classified as overweight ($23{\leq}BMI$ < 25). The percentile of those with a BMI of $25kg/m^2$ was 70, and they had 30.82% body fat. HDL cholesterol showed a negative correlation with anthropometric factors (height, weight, body mass index, waist circumference, waist hip ratio, body fat), and total cholesterol, LDL cholesterol, and triglycerides showed a positive correlation. Especially, total cholesterol, LDL cholesterol, and hip circumference showed significant correlations. Because of differences in the body fat and lean body mass by age group, it seems difficult to assess obesity via BMI only. The elderly especially should have a higher significance placed on body fat or abdominal fat than only BMI.

This study was conducted to investigate the nutrient intake, dietary and weight control behaviors and iron deficiency of adolescent girls. The subjects were 216 female middle school students living in urban and rural areas of Inchon. Thin cross- sectional study was conducted by questionnaires and data were analyze by SAS program. Nutrient intakes collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program(CAN-pro). The mean height, weight. BMI and obesity index for the subjects were 158.2 cm, 51.1kg, 20.4 and -5.3 % in urban students and 155.9 cm, 49.3 kg 21.1 and -8.2% in rural students, respectively. Easting blood samples were obtained and analyzed for iron nutritional status. The mean obesity index of the urban students was higher than that of the rural students. The proportion of the overweight group was higher in urban students compared to rural students, However, over 10% of both area students belonged to the low weight group, respectively. Most students of both areas skipped breakfast and the main reason was on appetite and lack of time. Urban students were more concerned with body image. The nutrients which showed a lower mean intake as percentile of RDA were Ca, iron, vit A an Vit B$_2$ and most nutrient intakes of urban students were significantly higher compared to those of rural students. These results indicate that nutrient intakes in the female middle school students were considerably lower than the RDA. Also they had undesirable food habits and lower self-satisfaction with their body image, There were significant differences in the mean MCV, TIBC and serum ferritin between urban and rural area subjects. Mean Hb, Hct, MCH, MCHC and TS, bowaver, were not significantly different. Prevalence of iron deficiency greatly varied by indices from urban(11.5%) and rural (8.7%) when judged by Hb to urban(23.1) and rural (23.3%) by serum ferrition. Therefore, proper nutrition education is required for good nutrition desirable food habits, weight control, and guidance for iron deficiency in anemic female of adolescents.

The objective of this study was to investigate the associations between the prevalence of overweight and obesity and the degree of adherence to the Korean Dietary Action Guides for Children (KDAGC). In a cross-sectional study based on a child care center-based survey in Seoul, Korea, we collected parental-reported questionnaires (n = 2,038) on children's weight and height, frequency of fruit and vegetable consumption, and the quality of dietary and activity behaviors based on the 2009 KDAGC Adherence Index (KDAGCAI) which was developed as a composite measure of adherence to the KDAGC. Overweight and obesity were determined according to age- and sex-specific BMI percentile from the 2007 Korean national growth chart. Associations were assessed with generalized linear models and polytomous logistic regression models. Approximately 17.6% of Korean preschool children were classified as overweight or obese. Obese preschoolers had lower adherence to the KDAGCAI compared to those with lean/normal weight. Preschoolers with a high quality of dietary and activity behaviors had a 51% decreased odds ratio (OR) of being obese (highest vs. lowest tertile of KDAGCAI-score, 95% CI 0.31, 0.78; P = 0.001); the associations were more pronounced among those who were older (P = 0.048) and lived in lower income households (P = 0.014). A greater frequency of vegetable consumption, but not fruit, was associated with a borderline significant reduction in the prevalence of obesity. Our findings support the association between obesity prevention and high compliance with the Korean national dietary and activity guideline among preschool children.

This study was to investigate the level of serum lipids and obesity in housewives in Mooan, and relationships between them. The average age, height and weight were 51.1 years, 154.3cm and 58.3kg respectively. The level of obesity of subjects was higher than that of housewives in other areas investigated in other studies. BMI and RBW underestimated in the obese compared to BIA. The amounts of lean body mass and total body water of subjects above 60 years old were smaller than those of forties and their BMI and RBW were lower than those of forties. However, their body fat percentage was nearly same as that of forties. Serum HDL-cholesterol(HDL-C) of subjects was lower than 55mg/㎗, the lower limit of normal range. Triglyceride of subjects above 60years old was higher than the 95th percentile of those of the same age with reference to Mayo clinic. The serum total cholesterol(TC) showed positive correlation with LDL-cholesterol(LDL-C) and TC/HDL-C(p<0.001). LDL-C showed positive correlation with TC(p<0.001), but negative correlation with HDL-C(p<0.05). HDL-C showed negative correlation with triglyceride(p<0.05). TC/HDL-C showed a positive correlation with triglyceride(p<0.05). HDL-C was the serum lipid which showed the highest correlation with obesity and body composition. It showed a negative correlation with the percentage of body fat(p<0.001), total body fat(p<0.001), BMI(p< 0.05) and RBW(p<0.05). TC/HDL-C showed positive correlation with the percentage of body fat(p<0.01) and total body fat(p<0.05). As the result of above, it is needed to make more researches to find out the proper method to estimate the obesity of subjects and educate subjects in Mooan about nutritional information for obesity.

The purpose of this study was to determine the probability of overweight throughout childhood in relation to the presence of overweight at birch or in early childhood, and presence of overweight in children's parents. Weight and height measures were collected at birth and at ages of 7, 10, 12 years from 655 6th grade primary schoolchildren. Childhood overweight was defined as a body mass index at or above the 85th percentile for age and sex, and overweight in children's parents as a body mass index at or above 27. The prevalence of overweight increased with age of the children. Overweight at birth was not associated with overweight at 12 years of ages. However, overweight at 12 years old was already related to overweight at 7 years old. In comparison to non-overweight peers, overweight children at ages 7(OR = 7.64, 95% CI = 4.32-13.51) and 10 years(OR = 19.69, 95% CI = 11.42-33.94) had a higher rick of becoming overweight at 12 years of age. Among children who was overweight at age 7years, 60.7% remained overweight 5 years later, Yearly increment in BMI of overweight children was larger than that of non-obese children (1.15-1.65kg/m$^2$vs 0.50-0.71kg/m$^2$. As compared with the lower case in mealy increment of BMI, the probability of being overweight at age of 12 years was greater in higher case. BMI values at age 7years were positively correlated with BMI values at age of 10 and 127ear,i, and with annual increments in BMI. But those relationships with birth weight were not observed. Children were at greater risk for overweight if at least ogle parent was overweight. The odds ratio for child overweight associated with maternal overweight was 2.41(95% CI = 1,13-5.IS), and those associated with paternal overweight 1.70(95% CI = 0.92-3.17). And parents' BMIs were positively correlated with children's BMI values and yearly BMI increment. In conclusion, overweight at early childhood and annual inclement in BMI can be important in predicting the prevalence of overweight and the risk that overweight will remain after 7 years of age. The risk of being overweight throughout the childhood increases by the parents'overweight.

The study examined BMIs, physical strength, activities, and the attitudes and behavior toward weight control among 7,968 Korean students{2,435 5th graders from elementary schools(ESs), 2,524 2nd graders from middle schools(MSs), 2,739 2nd graders from high schools(HSs)} nationwide. Compared to the 1987 data, there were increases of height(3-6cm) and weight(3-8kg), but decreases of physical strength and exercise. Lack of 'regular exercise' among girls from MSs and HSs and higher proportion of time spent on watching TV and using a computer for elementary schoolers were particularly noticeable. Proportions of students who were satisfied with their body weight were 49% for ESs, 35% for MSs, and 29% for HSs. There was no relationship between subjective and objective evaluations of body weight. Diet rather than exercise was more frequently chosen as a method of weight control. Compared to boys, girls showed stronger association between the amount of exercise and the subjective body weight in MSs and HSs, however this association was not found for the subjects from HSs. Values for the 50th percentile of BMI of boys and girls were 18.4 and 17.7 for ESs, 19.9 and 20.1for MSs, and 21.4 and 20.6 for HSs. In MSs and HSs, boys with BMI between 15th to 85th percentiles were physically stronger than those whose BMIs were lower than 15th kor higher than 85th percentiles. For the other groups, there was a trend of a positive relationship between BMI and physical strength. Based on the analyses of BMI and physical strength, this study suggests 22 and 21 for upper grades in ESs, 24 and 23 for MSs, and 27 and 25 for HSs as the respective cut off points of BMI for weight control n boys and girls. A need for implementing nutrition education program focused on weight control is also suggested.

From February 1982 to December 1991, 49 neonates and 105 infants in less than 3 months of age underwent open heart surgery in Seoul National University Hospital. There were 98 males and 56 females, and their mean ages were 16 days in neonatal group and 67 days in early infant group. Their body weight and height were less than 3 percentile of normal developmental pattern. In order of decreasing incidence, the corrected conditions included Transposition of great arteries with or without ventricular septal defect [43], isolated ventricular septal defect [34], Total anomalous pulmonary venous return [21], Pulmonary atresia with intact ventricular septum [9] and others [47]. Various corrective or palliative procedures were performed on these patients; Arterial switch operation [36], patch closure for ventricular septal defect [34], Repair of total anomalous pulmonary venous return [21], RVOT reconstruction for congenital anomalies with compromised right ventricular outflow tract [17]. Profound hypothermia and circulatory arrest were used in 94 patients [ 61% ]: 42 patients [ 85.7% ] for neonatal group and 52 patients [ 49.5% ] for early infant group. The durations of circulatory interruption were within the safe margin according to the corresponding body temperature in most cases [ 84% ]. The hospital mortality was 36.4% ; 44.9% in neonatal group and 32.4% in infant group 1 to 3 months of age. The mortality was higher in cyanotic patients [ 46.6% ], in those who underwent palliative procedures [ 57.8% ], in patients whose circulatory arrest time was longer than safe periods [ 60% 0] and in patients who had long periods of cardiopulmonary bypss and aortic crossclamping. In conclusion, there has been increasing incidence of open heart surgery in neonates and early infants in recent years and the technique of deep hypothermia and circulatory arrest was applied in most of these patients, and the mortality was higher in cyanotic neonates who underwent palliative procedures and who had long cardiopulmonary bypass , aortic cross-clamping and circulatory arrest.
