The purpose of this study was to obtain information from married women regarding obesity-related factors and psychological eating behaviors, and to compare those variables among three groups, namely underweight, normal, and obese. The participants completed questionnaires regarding general obesity-related factors, major food servings/day, physical activity, dieting behaviors, perceptions of body image, and psychological eating behaviors. The results were as follows: The obese women reported a higher percentage of family history of obesity (74.8%) than the normal (43.5%) or underweight (28.2%) women. Most of the obese women (90.0%) accurately perceived their body image compared to 72.5% of the underweight and 56.6% of the normal weight women(p<0.001). No significant differences were found among the three groups for daily hours of exercise or computer use. In the case of hours of television watched daily, significant differences were found among the groups (obese 104 min/day, normal 87 min/day, underweight 76/min, p<0.05). Only 17.9% of the obese women reported eating 2 servings of milk products/day and only 23.2% of them reported eating 3 servings of protein foods/day as compared to the normal (25.4%, 18.0%) and underweight (29.4%, 41.7%) (p<0.01) women. About 98% of the obese and 78.5% of the normal weight women wanted to loose weight compared to only 10% of the underweight women (p<0.001). Psychological eating behavior was significantly correlated with subject BMI ($r^2$=0.32, p<0.01). Also, more obese women were unsatisfied with their body and had emotional eating behaviors as compared to the normal and underweight women, and this was statistically significant (p<0.001). In conclusion, the obese women had high perception rates of their body image, but had negative-psychological eating behaviors. Special behavior therapy is needed for obese women who show body dissatisfaction, emotional eating behaviors, long hours of daily TV viewing, and low intakes of protein and milk products.

The purposes of this study were to investigate blood profiles and nutrient intakes of groups that are different in obese levels, and to find the credible predictor of insulin resistance. The subjects were classified as normal weight (%IBW${\leq}$ 110), obese without MS and obese with MS according to IDF definition of the risk group in metabolic syndrome (MS). Subjects of this study were included 137 (59 boys, 78 girls) free living children and adolescents (mean age $12.6{\pm}3.4$ years) in Gangneung area, South Korea. %IBW of normal weight (94.9%), obese without MS (123.8%) and obese with MS (131.5%) were significantly different among groups. HOMA-IR had positive correlations with TG (r = 0.634), waist circumference (r = 0.553), atherogenic index (r = 0.513), %IBW (r = 0.453) and ALT (r = 0.360), but showed negative correlations with HDL cholesterol (r = -0.417, p < 0.001). HOMA-IR showed positive correlation with polyunsaturated fatty acid intake (p < 0.05). The energy intake of obese with MS was 1762 kcal/day which was not significantly different from those of normal weight and obese without MS. Total fatty acid intakes of two obese groups were significantly higher than that of normal weight. The results of this study suggest that waist circumference and ALT as well as TG, atherogenic index and weight can be credible indices to predict the insulin resistance in children and in adolescents. In addition, nutrition education and adequate diet should be provided to prevent MS in children and in adolescents.

Anthropometry, computed tomography(CT) at the umbilical level, nutrient intake, blood pressure, serum levels of lipids and lipoproteins and response of glucose, c-peptide, insulin, and free fatty acid(FFA) during oral glucose tolerance test(OGTT) were estimated on 11 normal-weight controls and 35 overweight and obese middle-agd men. The areas of total abdominal, subcutaneous and visceral were determined by CT scanning technique. Total abdominal fat area correlated the most significantly with the levels of serum lipids, lipoproteins and insulin among several obese indices. Compared with normal-weight controls, overweight and obese men with abdominal fat lower than 29000$\textrm{mm}^2$ showed an increase in waist-hip ratio, areas of total abdominal(35%), visceral and subcutaneous fat and C-peptide response area during OGTT, though age, percent ideal body weight, body mass index, % body fat, and all biochemical indices except C-peptide response area were not different between two groups. Overweight and obese men with abdominal fat greater than 29000$\textrm{mm}^2$ showed a higher values in total abdominal fat(85%), serum levels of triglyceride, total-and LDL-cholesterol, the ratio of LDL-to HDL-cholesterol, and response areas of FFA, insulin and C-peptide during OGTT than normal-weight controls. Overweight and obese men with great abdominal fat showed an increase in alcohol ingestion and percent calorie intake per total energy expenditure, compared with normal-weight controls. Our results indicate that obesity and a certain level of total abdominal fat accumulation is required to observe abnormal levels of serum lipids, lipoproteins and insulin in Korean middle-aged men. In addition, increased alcohol and calorie intake and decreased physical activity could partly explain total abdominal fat accumulation in men.

Objective: Ramulus mori (RM) has been known to be effective for the treatment of obesity. To show the effectiveness of RM in a more scientific way, RM extract was prepared and evaluated in high fat diet rats by measuring the changes of body weight and lipid metabolism as described briefly below. Methods: 200 g of crushed RM was extracted withmethyl alcohol. The extract was evaporated under reduced pressure to give 33.4 g. For 10 weeks, control group rats were fed a high fat diet, while the test group rats were fed with the same diet plus RM extract. The normal group was fed with a normal diet. 150 mg of RM extract per 1 kg of body weight was added to the diet in the test group rats. Results: The control group rats on the high fat diet gained weight significantly, whereas the test group rats on the high fat diet plus RM extract gamed less weight. The significant increase of liver weight caused by the high fat diet was also inhibited by the RM extract treatment. Total lipid, triglyceride and total cholesterol levels of serum in the high fat diet rats were remarkably increased, whereastheir levels on the high fat diet plus RM extract were less increased. While serum HDL-cholesterol levels were remarkably decreased in the high fat diet, its level was less decreased in the high fat diet plus RM extract. Furthermore, we observed that the activities of hepatic acetyl-CoA carboxylase and fatty acid synthetase increased under the high fat diet, while their activities under the high fat diet plus RM extract were getting back nearly to the normal levels of the normal diet rats. Conclusions: These result show that the obesity caused by a high fat diet was effectively inhibited by an RM extract. Our results also showed that the abnormal lipid metabolism caused by a high fat diet was effectively cured by adding RM extract.

This study was conducted to prepare basic materials and offer advice regarding dietary habits to prevent and cure childhood obesity by comparing and analyzing dietary habit, nutritional status, blood factors, and mineral contents of hair. All subjects were stratified by their weight-length index (WLI). According to the standard WLI values, 64.9% of children were within the normal value, 13.5% of children were underweight, and 21.6% of children were overweight and obese (WLI ${\geq}$ 110%). Overall, the score assessed dietary habit for all children was $21.32{\pm}2.55$ point (921 subjects), with 5.1% of children having excellent dietary habits and 3.1% having poor dietary habits. Additionally, 37.9% of underweight children, 37.6% of normal weight children, and 43.2% of overweight and obese children consumed higher amounts of protein than underweight children did (meat, fish, eggs, and soy products) (P < 0.05). Overweight and obese children consumed more fried foods than underweight or normal weight children (P < 0.05). Moreover, 38.0% of the children had hemoglobin levels of 12 g/dl, while 7.6% were anemic (11.1 g/dl). When a hematocrit level of 33% was taken as the standard, 11.0% of children were anemic. The plasma transferrin content was $263.76{\pm}54.52$ mg/dl in overweight and obese children. The mean values of Fe, Cu, Ca, Cr, Mn, Se, Na, K, Li, V, Co, and Mo were within the reference values, but the Zn concentrations of underweight, normal weight, and overweight and obese children were $67.97{\pm}28.51$ ppm, $70.09{\pm}30.81$ ppm, and $73.99{\pm}30.36$ ppm, respectively. The Zn concentration of overweight and obese children ($73.99{\pm}30.36$ ppm) was lower than that of the standard value (180~220 ppm). Therefore, a nutritional education program and new guidance for dietary pattern should be developed to reduce the number of underweight and overweight and obese children.

Objectives: This study was performed to evaluate the effects of fermented Samjung-hwan (SJH) extracts on weight, serum lipids and blood glucose. Methods: SJH was fermented using three different probiotic bacterial strains (Lactobacillus plantarum [LP], Leuconostoc mesenteroides [LM], Bifidobacterium longum [BL]) separately. Thirty-six rats were divided into normal, control (high fat diet), SJH-UF (high fat diet+unfermented SJH 200 mg/kg), SJH-LP (high fat diet+LP fermented SJH 200 mg/kg), SJH-LM (high fat diet+LM fermented SJH 200 mg/kg) and SJH-BL (high fat diet+BL fermented SJH 200 mg/kg). For 8 weeks later, we examined body weight, total cholesterol, high-density lipoprotein (HDL)-cholesterol and blood glucose. Results: The control group showed significantly increased weight gain compared with normal group and SJH-LP and BL groups had less weight gain than control group, significantly. In the lipid serum tests, control group showed significantly increased total cholesterol levels compared with normal group and only SJH-LP represented decreased total cholesterol levels compared with control group. However there was no significant change in the HDL-cholesteol levels. In the blood glucose tests, that of control group significantly incereased more than that of normal group, SJH-BL showed significantly decreased blood glucose levels compared with control group. Conclusions: SJH-LP, SJH-BL showed weight control effect, SJH-LP decreased TC and SJH-BL reduced blood glucose.

This study investigated the recognition and utilization status of food labeling and nutrition labeling, according to the body type recognition of university students. In a total of 351 subjects, the male subjects comprised of 25.8% belonging to the underweight awareness group, 46.3% normal weight awareness group, and 27.9% overweight awareness students. Among the female students, 29.2% belonged to the underweight awareness group, 36.6% were normal body weight, and 34.2% were the overweight group. When purchasing processed foods, the price (4.05 points), expiration date (4.03 points), and gross weight (3.88 points) were the most considered factors of the food labeling content (5 points) for all body shape recognition groups. The food labeling of canned foods was checked most by the underweight awareness group (p<0.05). For bread and snacks, the contents of food labeling were confirmed most by the normal weight awareness group and the overweight awareness group (p<0.001). For beverages, the normal weight awareness group checked more food labels (p<0.01). The underweight awareness group (55.2%) hardly checked the nutritional labeling, and 22.9% of these subjects did not check at all. Our results may provide the necessity to improve the incorrect eating habits of students, by evaluating differences between the cognitive body type and the actual body type by BMI.

The purpose of this study was to compare the body compositions and food behaviors of middle aged men with different obesity indices. The subjects were 62 middle aged men who lived Gunsan city. Heights, body weights, soft/lean masses, fat masses, percentages of body fat, and fat distributions were measured. Food habits and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their percentage of body fat ($\%$Fat) ; normal, overweight and obesity. The results were as follows: their heights, fat masses, percentages of body fat, WHR, RBW, BMI and fitness scores were significantly higher in the obese subjects when compared to the normal and overweight subjects. Self-perceptions of weight and desires of weight control were significantly related with their percents of Fat. The overweight and the obese groups skipped meals, ate supper out, ate snacks, smoked tobacco, and exercised less frequently than the normal group. There were no significant differences in the scores of the dietary habits and drinking of alcohol among the three groups. Therefore, proper nutritional education on regular meals and intervention is required if middle aged men want to be of normal weight and have healthy lifestyles.

This study was carrid out to examine a part of the mechanism for the etiology of diabetic complications. Thirty normal and forty streptozotocin(STZ)-induced diabetic rats were used as the animal models. Animals were sacrificed at the time points of 3 days, 1, 2, 4 and 6 weeks after STZ-injection and time course in body weight and organ weight, the levels of blood glucose, plasma lipid patterns, and atherogenic index were measured during 6 weeks. The STZ-diabetic animals showed 63% survival rate and fsting blood glucose levels of the diabetic animals measured in the range of 230-410mg/dL during the experimental period. The body weigh of diabetic animals decreased significantly throughout the experimental period and the relative weights of organs to body weight were significantly higher than the normal control ones. The enlargement of the kidney in the diabetic animals was especially remarkable. Plasma triglyceride concentration in diabetic rats substancially increased from the first week of onset of diabetes mellitus and maintained higher levels than the control ones throughout the whole experimental period. The plasma total cholesterol level and atherogenic index in the diabetic rats were significantly higher than the normal ones from the third day after STZ injection and showed a gradual increase with the duration of the disease. Throughout the experiment, the diabetic rats consistently showed a slightly lower HDL-cholesterol level compared to the normal animals. From the results of this study, it appears that the significant changes in blood lipid pattern in STZ-diabetic animals start from the first week after STZ injection.
