This study examined the effects of calcium intake on body weight and body fat in female college students. Surveys were conducted using a 3 day dietary record of 248 female university students in Korea. The subjects were divided into three groups by percent body fat. There was no significant difference in energy intake among the three groups. The intake of calcium the obese group was lower than that of other groups but it was not significantly lower. There was a negative correlation between yogurt intake and body fat in the normal group. The study did not discover a correlation between calcium intake and body fat. However, our results might encourage further research in finding a possible role of dietary calcium in the prevention of obesity.

The purpose of this study is to determine the effect of a health management program on body composition(body weight, body fat mass, body fat ratio, lean body mass, abdominal fat ratio), self-efficacy and health promotion behavior in middle-aged women. This 6-week long program containing exercise and health education was developed by researchers. The study design was one group pretest-posttest design. Data for the study was collected from August 1 to September 15, 2002. The participants consisted of 15 middle - aged women living in the community. The collected data was analyzed using Wilcoxon Matched - Signed - Ranks Test by SPSS/WIN program The results are as follows : 1. There was a significant difference in body composition at week 6 compared to week 1. The body weight, body fat mass and body fat ratio significantly decreased(Z= -2.533, p=. 011 ; Z= -2.023, p= .043; Z= -2.023, p= .043). But the lean body mass significantly increased(Z= -2.226, p= .026). 2.There was a significant improvement in self-efficacy at week 6 compared to week 1(Z= -3.434, p= .001). 3.There was a significant improvement in health promotion behavior at week 6 compared to week 1(Z = -3.305, p= .001). In conclusion, health management program promoting self - efficacy for middle-aged women was effective in improving health promotion behavior. Further study with a longer follow up period is necessary in order to test the long term effect of the program.

Objectives : The objective is that we measure and analyze Pulse-Respiration Ratio and Body Composition Analysis to study the correlation between both. Methods : First, after subjects take a rest over 10 minutes, we measure their electrocardiogram and respiration pattern through which we take average peak interval to calculate an average pulse cycle and a respiration cycle. An average respiration cycle divided by an average Pulse Rate gives Pulse-Respiration Ratio. Next, we draw out 22 Body Composition Analysis indicators by using In-Body 720 model. Last, we analyze and take statistics on them by using SPSS 13.0 program. Results : Negative is the correlation between P/R Ratio and Body Composition Analysis indicator like fatness degree, body fat volume, body fat rate, abdominal fatness, BMI. Conclusions : 1. The higher P/R Ratio the more likely to be thin, the lower P/R Ratio the more likely to be fat. 2. We separately analyze P/R Ratio depending on each breathing frequency and pulse frequency to find out that breathing frequency has great influence and that breathing frequency decides the fatness degree. 3. In study on the correlation between P/R Ratio and Body Composition Analysis, fatness degree, in-body fat volume, in-body fat rate, BMI are the related indicators, which shows the connection with the fatness indicators. 4. In study on the correlation between Han-Yeol [寒熱] grade and Body Composition Analysis indicators, the result is that Han[寒] has no connection and that only Yeol[熱] grade has something to do with it, which means the higher heat symptom subjects have, the more basic metabolism volume and muscular build they have.

Objective: To study the effect of body composition on reproduction in women with unexplained infertility treated with a controlled ovarian hyperstimulation and intrauterine insemination programme. Methods: This prospective observational study was conducted on 308 unexplained infertile women who were scheduled for a controlled ovarian hyperstimulation and intrauterine insemination programme and were grouped as pregnant and non-pregnant. Anthropometric measurements were performed using TANITA-420MA before the treatment cycle. Body composition was determined using a bioelectrical impedance analysis system. Results: Body fat mass was significantly lower in pregnant women than in non-pregnant women ($15.61{\pm}3.65$ vs. $18.78{\pm}5.97$, respectively) (p=0.01). In a multiple regression analysis, body fat mass proved to have a stronger association with fecundity than the percentage of body fat, body mass index, or the waist/hip ratio (standardized regression coefficient${\geq}0.277$, t-value ${\geq}2.537$; p<0.05). The cut-off value of fat mass, which was evaluated using the receiver operating characteristics curve, was 16.65 with a sensitivity of 61.8% and a specificity of 70.2%. Below this cut-off value, the odds of the pregnancy occurrence was found to be 2.5 times more likely. Conclusion: Body fat mass can be predictive for pregnancy in patients with unexplained infertility scheduled for a controlled ovarian hyperstimulation and intrauterine insemination programme.

Purpose: The aim of this study was to examine BMI, body fat mass, percent body fat, waist-hip ratio, soft lean mass, skeletal muscle mass, and fat free mass, and to determine the association between dietary behavior and exercise and body composition among students at women's colleges, and decide on the relationships among them. Method: This study employed a cross-sectional study design and a convenient sampling method. Ultimately, a total of 404 students participated in the study, which was conducted from September 1 to December 22, 2009. Measurements administered were comprised of dietary behavior and a questionnaire on exercise. The SPSS Win 18.0 statistics program was used for analysis of final data. Results: Major findings are as follows: 9.9% of participants showed a high BMI, and more than 56% and 38% of participants showed a high percent body fat and waist-hip ratio, respectively. Dietary behavior showed a significant negative association with percent body fat (r=-0.110, p=0.027) and waist-hip ratio (r=-0.118, p=0.018). Compared with the non-regular exercise group, the regular exercise group showed a high level of soft, lean mass (t=4.15, p<0.001), skeletal muscle mass (t=3.13, p=0.002), and fat free mass (t=4.00, p<0.001). Conclusion: For maintenance of proper body composition, health promotion programs for management of dietary behavior and regular exercise for students at women's colleges should be developed.

Obesity can be defined as a metabolic disease due to an increased fat accumulation in the body caused by an imbalance of calorie intake and output The prevalence of obesity has increased substantially over the past 2-3 decades in developed and developing countries. The health impact of weight gain is so marked that obesity has now been classified as a major global public health problem In order to investigate the effect of diet conversion and oral administration of Platycodon grandiflorum extracts on the treatment of obesity, male Spraque-Dawley rats were divided into four groups: a group converted to normal diet (Control group), a group maintained high fat (30%) diet (H), and two groups with Platycodon grandiflorum extract added to the previously mentioned two groups. All animals were fed high fat diet for 7 weeks to induce the obesity. Then they were divided as mentioned above. Animals were fed experimental diet and Platycodon grandiflorum extract (150 mg/ml/rat/day) for 7 weeks. Body weight, adipose tissue weight (subcutaneous, epididymal, peritoneal fat pads) and serum lipids (total cholesterol and triglyceride) showed some differences among groups. The Platycodon grandiflorum feeding markedly decreased both body weight and adipose tissue weight in control group compared to H, high fat diet maintaining, group. Platycodon grandiflorum extracts significantly decreased the concentrations of serum lipids compared to H group. Fat cell numbers and sizes were significantly reduced in the oriental medicinal herb extract administrated group. Increased fatty acid binding protein (FABP) expression in high fat diet group was decreased by the dietary conversion to normal diet and the oral administration of Platycodon glandiflorum extracts. In contrast, there was no significant effect on FABP expression in the high fat maintenance group. In this study, the conversion from high fat diet to low fat or normal diet had a beneficial effect on body weight loss and serum lipid profiles. Dietary Platycodon glandiflorum extracts had an additive beneficial effect on the prevention and treatment of obesity.

Obesity usually is defined as the presence of and abnormally amount of adipose tissue. In many epidemiologic study, obesity as a health risk factor has been estimated by Body Mass Index(BMI) in general. This study was conducted to review of body fat percent measured by Bioelectric impedance analyzer as a estimator of obesity in a rural adult population. The study subjects were 421 men and 664 women who reside in the area on the Juam lake. They were sampled by multistage cluster sampling. Their mean age was 59 years old. Body fat percent increased with age, but BMI decreased with age in this study. Body fat percent was more larger at female and elder on the same BMI. The correlation coefficient between with body fat percent and body mass index was low (r=0.4737). Body fat percent was explained by not only BMI but also sex and age $(r^2=0.63)$. The result suggested that it is inadequate for BMI only to estimate obesity about elderly person who reside in the rural community. The relation of body fat percent and body mass index of this study agreed with the preceding know-ledges and studies in general.

Body fat-reducing ability of oyster mushroom (Pleurotus ostreatus) water extract (OMWE) was investigated of mice by supplying it drinking water. OMWE(2.95% solid content ) was prepared by extracting a low grade of the mushroom at 12$0^{\circ}C$ for 10min. The solid material of OMWE was composed of 65.2% reducing sugar, 0.23% crude fat, 0.5%total protein, 1.2% ash and 32.9% others. OMWE was appropriately diluted with drinking water. Seventy two male ICR mice(25$\pm$1 g, 7~8 weeks of age, 6 mice/cage, 18 mice/treatment) housed in polycarbonate cages containing $\beta$-chips were adopted in a temperature-and humidity-controlled facility with free access to water and diet. One week later, the mice were subjected to one of the treatments for 36days : 0 (control), 10, 50 and 100% OMWE. Drinking wter with or without OMWE was supplied twice (40ml each, 80ml in total ) daily per cage. Body weight and fed intake were recorded every three days. At the end of the experiment, mice were sacrificed to determine the chemical composition (fat, protein, ash and water). Body weight of mice treated with OMWE (10, 50 and 100%) at day 36 was 35.9, 35.9and 35.5g per mouse , respectively, and not significantly reduced as compared to that (36.5g/mouse) of control mice. Average body fat of 0,10,50 and 10% OMWE -treated mice was 14.3, 13.1, 10.7 and 12.0% , respectively. Body fat reduction by 50% OMWE treatment was 25.2% (p<0.05) relative to control. OMWE did not affect feed intake. The contents of body protein and ash were increased with respect to body fat decrease, while water content was not changed much. These results suggest that OMWE could reduce body fat of the mice without body weight change, giving the best effect by 50% OMWE.
