This study was conducted to identify the relationship between body fat percent/serum lipid level and obesity index among school children. The study subjects were 277 boys and 266 girls aged between 10 and 11 years old in a selected elementary school in Taegu City. The survey was conducted for the period of two months from May 1 to June 30, 1993. A $R{\ddot{o}}hrer$index(weight/height3) was calculated for each individual as a measure of obesity. Three groups were classified as underweight($R{\ddot{o}}hrer$ index < 109), normal($109{\leq}$ $R{\ddot{o}}hrer$ index < 140), and overweight ($R{\ddot{o}}hrer$ index ${\geq}140$). As for the body fat percent, fat weight, lean body mass were measured by impedance fat, meter(Model SIF-891). Serum total cholesterol. high-density lipoprotein, and triglyceride were measured by automated clinical chemistry analyzer(Astra system). Obesity was found 18.1% in boys and 14.7% in girls. Body weight, fat percent, fat weight, and lean body mass were significantly different among three groups classified by $R{\ddot{o}}hrer$ index in both sexes. Serum total cholesterol, triglyceride, atherogenic index and T-CHO/HDL ratio were also significantly different among three groups in both sexes. Serum total cholesterol, low-density lipoprotein, trigylceride, atherogenic index of boys were positively correlated with height, weight. $R{\ddot{o}}hrer$ index, fat weight, lean body mass, and triglyceride. The negative correlation was found in high-density lipoprotein against height, weight, Rohrer index, fat percent, fat weight, lean body mass. Triglyceride and atherogenic index of the girls were positively correlated with height, weight, $R{\ddot{o}}hrer$ index, fat percent, fat weight, lean body mass. The negative correlation was found in high-density lipoprotein against height, weight, $R{\ddot{o}}hrer$ index, fat percent, fat weight, lean body mass. These findings suggest that the prevention of obesity and hyperlipidemia among school children is very important. Thus adoption of healthy life-style is strongly recommended in school health programs in order to prevent the obesity and hyperlipidemia.

Purpose :To analyze body composition in postpartum women with cold-hypersensitivity, their edema index, skelectal muscle's weight and body fat were measured and analyzed with cold hypersensitive postpartum women compared with those of non-cold hypersensitivity. Methods : We studied 38 postpartum women visiting Gangnam Kyung-Hee Korean Hospital from 1 st October 2010 to 30th september 2011. they were subjected to Digital Infrared Thermal Imaging and those with thermal difference greater than $0.3^{\circ}C$ between anterior forearm and center of hand were diagnosed with cold hypersensitivity. Cold hypersensitivity group were consisted of 11 women, the other were consisted of 26 women. All of them were measured Edema index, skelectal muscle's weight and body fat by Inbody720(body composition scanner). We studied the difference of Body composition factor between two groups and relationship between cold-hypersensitivity, Edema index, skelectal muscle's weight and body fat by Independent Samples T-test and Spearman Correlation. Results : No significant differences were observed in edema index, skelectal muscle's weight and body fat between two groups. Conclusion : There was no significant relationship among the Cold-hypersensitivity and Body composition factor(Edema index, skelectal muscle's weight. body fat). But furthemore large scale study is required.

A survey on the nutritional state was conducted from June 11 to Nov. 30, 1971, on 673 women workers $(16{\sim}25\;yrs)$ Jorking in a factory of food industry. Total body fat content was measured by skin-fold thickness (S. F. T.) with caliper at three region of the body. And it was calculated by regression equation, with the following conclusions were abtained. 1. The mean with standard deviation body height and weight of the Korean women workers were $155.0{\pm}4.21\;cm$ and $50.1{\pm}5.31\;kg$; respectively. 2. Their mean skin-fold thickness with their standard deviation triceps region of upper arm, 14.3{\pm}3.42$; Subscapular region, $18.0{\pm}5.57mm$; Abdominal region, $19.3{\pm}4.87mm$ and total aveager, 17.2{\pm}3.91mm$. 3. The body fat contents according to body fat weight regression equation were;fat weight. 10.7 kg; fat-free weight, 39.4kg; fat weight/ fat-free weight, 27.5%; fat-free mass/ total body mass 77.6%, and fat weight/ total body mass,21.6%. 4. Since the sknin-fold thickness between the triceps and upper abdominal region and between the former and Subscapular region were correlated with the coefficients of 0.838 and 0.615 respectively. and the following regression equations were established. a) S. F. T. of Subscapular region $(mm)=0.929{\times}$S. F. T. of triceps region (mm)+4.707. b) S. F. T. of Abdominal $region(mm)=1.24{\times}$S. F. T. of triceps region(mm)+1.50. Nutritional survey on the women workers in a fact ory of food industry, performed as above by the S. F. T. method, elucidated the fact that their nutritional state is as good as the control healthy female, and that their energy uptake may well be said to be satisfactory.

Anti-obesity effect of biocellulose and diet formulation containing it was evaluated using obese rats. Thirty male Sprague-Dawlely (SD) rats were randomly assigned to high-fat diet group (CON), high-fat diet group containing 5% biocellulose (BIO), and high-fat diet group containing 5% dietary formulation (DF). After 10 weeks, body weight gains of BIO and DF groups were reduced by 15.1 and 6%, respectively, as compared with CON group. Epididymus, parirenal, and visceral fat pads of BIO and DF groups were lower than those of CON group. Weight of interscapular brown adipose tissues increased slightly in BIO group and significantly in DF group. Size of adipocyte in rats decreased in BIO and DF groups. Results indicate biocellulose-containing diet has anti-obesity effect by reducing body weight gain and white adipocytes depots in rats fed high-fat diet.

Objectives : This study was aimed to investigate the change of the reduction in body weight and the change of body composition after fasting therapy, Chulsikyopub, which was put into practice in Dept. of oriental rehabilitation medicine at Kyung Hee oriental hospital. Method : We measured body weight, body composition, and the degree of obesity 2 weeks after fasting therapy and 10 weeks after fasting therapy with body composition analyzer(Inbody 2.0). Statistical comparisons between pre-therapy group and post-therpay group were done by paired t-test and Wilcoxon's signed rank test. Results : 2 weeks after fasting therapy, body weight was decreased 7.33kg(9.18%), body fat was decreased 2.47Kg(7.24%), muscle weight was decreased 4.66kg(11.37%), body fat ratio was increased 1.08%, and body metabolic rate(BMR) was decreased 118.23kcal(8.22%). 10 weeks after fasting therapy, each of body weight and fat was decreased 10.4Kg, muscle weight was increased 0.3Kg(0.7%), body fat ratio was decreased 7.9%, and BMR was increased 6.8Kcal(0.47%). But muscle weight and BMR did not satisfy statistical significance. Conclusions : fasting therapy for 10 weeks reduced body weight and body fat statistically significant without loss of muscle weight and BMR.

This study was aimed to investigate the relations between self-selected intake of 3 macronutrie-nts and body weight gain and body fat accumulation in male rats given three isocaloric diets differing carbohydrate protein and fat contents concurrently. Also the effect of dietary restriction was observed. Forty two male rats of Sprague-Dawley strain weighing 68.7$\pm$6.1g were randomly divided into 2 groups and were allowed to have foods from 3 different cups for 8-hours a day or ad libitum, After 12 weeksthey were decapitated and their brains were quickly removed and frozen until they were assayed for serotonin and its metabolite 5-HIAA The carcass was dried at 105$\pm$2$^{\circ}C$ and measured the contents of body water and body fat. The animals chose a moderately high and constant carbohydrate level and showed the increase of percent protein intake with age and great individual variations. Protein in the diet seemed to trigger appetite and increase food intake which resulted in higher weight gains and in more fat deposition in the body. The concentration of brain serotonin did not show any correlations with the intake of nutrients. the accumulation of body fat and the gain of body weight.

Objectives : This study was performed to identify the effects of high frequency therapy on localized obesity. Methods : This trial was carried out in 12 volunteers. Volunteers were divided into 3 groups; upper arm group (n=4), thigh group (n=4) and abdomen group (n=4) according to local obesity type. Body weight and body fat were measured by Inbody 720 and CT (Computed Tomography) immediately before and following high frequency therapy. Diathermy was performed twice a week for 4 weeks for a total of 8 treatments. Results : In the upper arm group, body weight, body fat mass, fat area by CT scan and circumference were increased after treatment but not significantly (p>0.05). In the thigh group, body weight, body fat mass and circumference were decreased and fat area by CT scan was increased but both not significantly (p>0.05). In the abdomen group, significant differences were not found despite decreases in body weight, body fat mass, visceral fat and subcutaneous fat after diathermy (p>0.05). Conclusions : There was no significant effects of high frequency therapy on localized obesity.

The purpose of this study was to investigate the effects of wax gourd on body weight, body fat, triglyceride, leptin and fat cell size in rats fed medium fat Male Sprague Dawley rats were fed with experimental diet containing total dietary fat at 20% of calorie with wax gourd (WG) for 4 weeks. Forty rats were divided into 4 groups including control, 5, 10, and 15% (w/w) WG supplement The results showed that weight gain was significantly higher in 5% WG than that in control (p<0.05), but was not different among the WG supplement groups. Total fat weight was significantly decreased in both 10 and 15% WG supplement groups than that of control. The levels of triglycerides and free fatty acids in the plasma were significantly decreased, particularly in 15% WG supplement group (p<0.05). The levels of leptin was not significantly different among the experimental groups. Fat cell size was significantly decreased in WG supplement groups compared to that of control group (p<0.05). Correlation among the parameters demonstrated that weight gain correlated positively with total fat weight, the levels of leptin and triglycerides. Taken these results together, 15% WG supplement diet substantially reduces total fat weight, triglycerides and free fatty acids levels and fat cell size in the rat fed midium fat.

The purpose of this study is to analyse the effects of obesity management program in food attitude and food habit, body composition(body fat ratio, body fat weight, lean body mass, total body water), abdominal girth(waist, hip, thigh), and serum lipid level(cholesterol, low density lipoprotein, triglyceride, phospholipid, NE fatty acid, high density lipoprotein) of middle aged women. Data for the study were collected from July 4 to August 25, 2000. The study objects were 20 middle aged women(10 controls and 10 experimental objects) from 40 to 50 years old who had body fat ratio more than $30\%$ and waist girth more than 80cm. The results were as follows: 1. Similarity test between experimental group and control group processed by serum HDL level showed the significant difference(t=3.25, p=0.004), but that processed by age, body weight, body fat ratio, body fat weight, lean body mass, total body water, waist girth, hip girth, thigh girth, cholesterol level, LDL level, triglyceride level, NE fatty acid level, food attitude and food habit score showed no significant difference(p>0.05). These findings imply that the two groups are similar in the sample distribution. 2. The effects of the abdominal obesity management program The obtained results indicate that the abdominal obesity management program in middle aged women changes the food attitude & the food habit. decreases the body fat ratio & the body fat weight and increases the lean body mass, and decreases the girth of waist & hip and the serum level of cholesterol & LDL. Therefore, it is concluded that the abdominal obesity management program can be applied for nursing intervention to decrease the body fat weight and abdominal obesity.

Purpose: Somatotype drawing developed by Sorensen et al.(1983) has been evaluated as a simple instrument of obesity level without real somatic measuring as height and weight. This study was designed to validate somatotype drawings for obesity assessment by bioelectrical impedance body component analysis. Method: At first questionnaire of somatotype drawing was done. Subjects were measured body component by bioelectrical impedance analysis as weight, BMI(body mass index), WHR(waist-hip ratio), body water, protein mass, mineral mass, body fat mass, skeletal muscle mass, soft lean mass, fat free mass and percent body fat. We evaluated correlations between these data and somatotype drawings and tried to grouping of somatotype drawings with the means of major body component value. Result: The data were collected from 205 college women whose height and weight were $161.2\pm4.8,\;55\pm8.3$. Spearman's correlation coefficients of somatotype drawing were 0.74 with BMI, 0.68 with weight 0.69 with body fat mass, 0.65 with WHR. 0.64 with percent body fat after adiusted age. The grade of somatotype drawings were grouped as 1-2, 3-4, 5-6. 7-9 by BMI, body fat mass, weight, 1, 2-4, 5-6, 7-9 by WHR and 1-2, 3-4, 5-9 by percent body fat(ANOVA and Duncan's method). Conclusion: So quick instrument using somatotype drawings were useful tools for evaluation of obesity level and is applicable to screen degree of body fat in self-administered questionnaire survey.
