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.

The body fat distribution and nutritional state of the Korean and Japanese young female subjects were compared. Three-day individually weighed, dietary intakes and anthropometric measurements were determinded in 48 Korean and 60 Japanese female students. 19 to 23 yr of age, from the divisions of nutritions. The body composition estimates were measured by bioeletrical impedance-total body water(BI-TBW) method. There were no significant difference between the Korean and Japanese young females in body size and body shape. The Korean young females had lower estimated total body fat and internal fat that calculated by BI-TBW method, but there was no great difference between the Korean and the Japanese in subcutaneous fat. In contrast, the Korean young females are reported to have the same total energy expenditure per day as the Japanes young females and the total energy intakes and carbohydrate energy intake ratio per day were significantly higher than those of the Japanese young females. The difference in body fat distribution and energy intakes in Korean, and the role of capsaicin in red pepper are discussed as a possible determinant of the internal fat in the Korean vs the Japanese.

This study was conducted to investigate the relationship between body fat content and serum lipids in college students. A total of 61 (15 males and 46 females) students of W university in Iksan, between June 2015 and July 2015, were enrolled for analysis. The relationship of serum lipid with BMI, and body fat percent measured by impedance fat meter (InBody 520) was analyzed. The study population was divided into three groups according to the InBody 520's guideline. Group I accounted for 26.7% of men and 10.9% of women. Weight and BMI were significantly different among the three groups in men and women (p<0.05); whereas height was not. In men, serum total cholesterol, triglyceride, low density lipoprotein cholesterol, and hemoglobin were significantly different between the three groups (p<0.05). Conversely, in women, serum total cholesterol, low density lipoprotein cholesterol, and alanine transferase were significantly different between the three groups (p<0.05). However, there were no differences in other variables between the three groups. BMI was significantly different among three groups in both men and women (p<0.05). In men and women, body fat percent was correlated with BMI, weight, total cholesterol, and low density lipoprotein cholesterol. Multiple regression analysis on total cholesterol indicates that body fat percent, BMI, and hemoglobin were not significantly independent variables in men and women. This study showed that body fat percent was significantly associated with other obesity markers and serum lipids.

Objectives : Man adapts himself to nature, so accordingly as he grows up, changes of body composition appear. This study measured the changes of body compositions on the ground of Sasang constitution and seasons Methods : 253 middle school students who live in Busan were studied from the 20th of March, 1999 to the 20th of March, 2001. We measured height and body compositions with Inbody 3.0, six times during that period. Results : According as they grew up, total body water, muscle area, body weight, BMI (Body Mass Index), BMR (Basal Metabolic Rate), ACM (Arm Muscle Circumference), and BCM (Body Cell Mass) increased, but fat body weight ratio decreased. From March to June, total body water, muscle area, height, ACM, and BCM increased. From September to December fat body weight, fat body weight ratio, waist hip ratio increased as compared with other seasons. Height of Soyangin and BMI of both Soyangin and Taeumin increased more than those of other groups, with statistical significance Conclusions : The growth of man is adapting oneself to changes of nature, and it corresponds to the theory of (correspondence between man and universe).

Background: The rising prevalence of asthma may be associated with the rising prevalence of obesity in developed nations. There are several studies showing that obesity increases the risk of asthma in adults. We investigated the association of each body composition scale and bronchial hyper-responsiveness. Methods: This study involved a retrospective review of the existing records for 279 subjects with respiratory symptoms, who underwent a pulmonary function test, a methacholine challenge test and a body composition test between May 2007 and June 2009. Results: Of the 279 subjects, 179 (64%) were female. There was a statistically significant difference in fat free mass and in fat free mass index between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.036; p=0.000). There was no significant differences in body mass index, in fat mass and fat free mass index in the normal bronchial responsiveness group and bronchial hyper-responsiveness group in males. However in females, body mass index and fat free mass index were increased in the bronchial hyper-responsiveness group (p=0.044; p=0.000). Total body water (kg), fat free mass (kg) and soft lean mass (kg) were significantly different between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.002; p=0.000; p=0.000). Conclusion: This study showed significant differences in fat free mass and in fat free mass index between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. In females, BMI, soft lean mass, and total body water showed significant differences between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. We concluded that bronchial hyper-responsiveness was associated with not only body mass index but also fat free mass index in female bronchial asthma.

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.

The effects of capsaicin, a pungent principle of hot red pepper, on body fat gain, balance serum lipid values were investigated in rats fed a high-fat(30%) diet. Administration of capsaicin by dietary administration caused a complete cessation of increased in body weight and fat gain induced by the high-fat diet. However, energy intake and body protein gain were not affected by capsaicin. Therefore, the suppression of body fat gain by capsaicn was believed due to an increased in energy expenditure. Simultaneous administration of capsaicin and a $\beta$-adrenergic blocker, propranolo, resulted in the inhibition of changes in body fat gain by capsaicin without remained unchanged, indicating an increase in the number of mitochondria in brown adipose tissue. Therefore, it appears that capsaicin possesses potent body fat suppressive effects mediated by $\beta$-adrenergic stimulation in which brown adipose tissue may be involved. On the other hand, capsaicin had no effects on serum triglyceride, total cholesterol or HDL-cholesterol levels. These results are in contrast to those reported by other investigators. Perhaps expression of the effects of capsaicin on plasma lipids is a rather complicated process, dependent on the type of diet administered, fat content of the diet, period and route of capsaicin administration, and species and strain of animals used.

The study was conducted to investigate the effects of dietary calcium and soy isoflavone on body fat and lipid metabolism in high fat-induced obesity. Four week old female C57/BL6J mice, known as a good model of diet-induced obesity, were fed low Ca and high fat diet for 6 weeks. After induced obesity, mice were divided into six groups according to diets varying calcium contents (0.1 or 1.5%) and genistein contents (0 or 500 or 1,000 ppm). Body weight, fat pad (perirenal fat and parameterial fat), adipocyte size, serum total lipid and total cholesterol were significantly decreased by both high Ca intake and genistein supplementation. However, the effect of genistein supplementation showed in low Ca-fed groups. Serum LDL-cholesterol and TG were significantly decreased by high Ca intake and genistein supplementation, respectively. In liver, lipogenic enzymes (fatty acid synthase and malic enzyme) activity and TG were significantly decreased by both high Ca intake and genistein supplementation. This inhibitory effect of genistein on lipogenic enzymes showed in low Ca-fed groups. But liver total cholesterol and total lipid were significantly decreased by high Ca intake and genistein supplementation, respectively. Fecal excretion of total lipid, total cholesterol and TG were significantly increased by high Ca intake, not by genistein supplementation. In conclusion, high calcium intake and genistein supplement may be beneficial for suppression of obesity through direct anti-adipogenesis by decreasing fat weight and size and indirect anti-lipo-genesis by inhibiting lipogenic enzymes activity and improving lipid profile.

Anti-obesity effect of a new dietary supplement (3D-relax) in high-fat fed rats. The aim of this study was to assess the effects of 3D-relax; a proprietary formulation containing hydroxycitrate (233 mg/g), carnitine (150 mg/g) and red pepper (150 mg/g); on body weight, body fat, and serum lipids levels in rats fed a high-fat diet. Male SD 7-wk-old rats (n=8) were fed a high fat diet [52% total dietary energy (E%) from fat, 15.4 E% protein, 32.6E% carbohydrate] with or without 3D-relax administration (1 g/kg body weight/day) for 3 weeks. Administration of 3D-relax significantly reduced the increase in body weight compared to the group fed high fat without 3D-relax. Food efficiency ratio (FER) tended to be decreased with administration of 3D-relax, but was not significant. The perirenal and epididymal fat pad weights of vats administered 3D-relax were significantly lower than those of the high fat group that did not ingest 3D-relax during the 3 weeks. The oral administration of 3D-relax significantly increased HDL-cholesterol level and lowered total cholesterol level compared to those of high fat alone group. These results suggest that 3D-relax reduced body weight and fat gains, and those effects are presumably linked to its inhibitory effects on lipogenesis.

Three hundred and twenty-four 1 day old chicks were used to determine the effects of fat source and energy to protein ratio on growth performance , carcass composition and the efficiency on nutrient utilization. Chicks were assigned. in a completely randomized design, to 3*3 factorial arrangement of treatments. Chicks received one of three fat sources (n0 fat, tallow, corn oil) and one of three energy to protein ratios(16, 14 and 12kcal ME/g CP). All diets were formulated to be isocaloric(3.2Mcal ME/kg diets) using published ME values for the diet ingredients. Addition of tat to the diet increased ADG, average daily feed intake, and gain to feed, Chicks fed diets containing fat had increased percentage body DM and ether extract(EE), but percentage CP was not different, Chicks fed diets containing fat had increased efficiency of protein and energy deposition. Addition of fat ad either fallow or corn oil yielded similar results. Reducing the energy to protein ratio of the diet did not affect ADG or gain to feed, but tended to decrease average daily feed intake(p=0.80), as well as resulting in linear(p<0.05) reductions in body percentage DM., EE and also total EE. Increasing the energy to protein ratio did not affect percentage or total body Cp. Adding fat to poultry diets improved growth performance and the efficiency of growth chicks. Decreasing the energy to protein ratio did not affect growth performance, but reduced EE in the body of Chicks.
