Purpose : We investigated the correlation between body composition and lung function in healthy adults. Methods : This study included 204 healthy adults in whom all measurements were obtained once, and all data were analyzed using the SPSS software for Windows, version 22.0. Pearson's correlation analysis was performed to determine the correlation between body composition (represented by the total body water, protein mass, soft lean mass, mineral mass, basal metabolic rate, fat-free mass, skeletal muscle mass, and body fat percentage) and lung function (represented by the forced vital capacity [FVC], forced expiratory volume in 1 second [FEV₁], the FEV₁/FVC ratio, maximum voluntary ventilation [MVV], maximum expiratory pressure [MEP], and the maximum inspiratory pressure [MIP]). All measurements were obtained by two investigators to improve reliability. A significance level of α=.05 was used to verify statistical significance. Results : Among the lung function measurements obtained in both men and women, the FVC, FEV₁, MVV, and MIP were positively correlated with the total body water, protein mass, soft lean mass, mineral mass, basal metabolic rate, fat-free mass, and skeletal muscle mass in men (p<.05). The FEV₁/FVC ratio was negatively correlated with the total body water, soft lean mass, mineral mass, basal metabolic rate, fat-free mass and the body fat percentage (p<.05). Notably, the FVC, FEV₁, and MVV were positively correlated with the total body water, protein mass, soft lean mass, mineral mass, basal metabolic rate, fat-free mass, and skeletal muscle mass in women (p<.05). Conclusion : This study showed a significant correlation between body composition and lung function in healthy adults. In combination with future studies on lung function, our results can provide objective evidence regarding the importance of prevention of lung disease, and our data can be utilized in rehabilitation programs for patients with respiratory diseases.

Objectives : This study was aimed to show the effect of electroacupuncture combined with magnetic acupuncture on abdominal obesity without patient dieting, exercise or use of herbal medication. Methods : Women over 85 cm in waist circumference were treated with electroacupuncture combined with magnetic acupuncture. Acupuncture points were located at the abdomen ($CV_{12}$, $CV_6$, $ST_{25}$, $ST_{21}$, $SP_{15}$, $SP_{14}$), extremities ($LI_4$, $LI_{11}$, $ST_{36}$, $ST_{44}$) and were stimulated 30 minutes with 2.1~3 Gaus, 500 Hz, tolerable strength. The Interference wave forms were by Whata 153 (Medi Lab, Korea). Two or three treatment sessions per week (five or ten sessions in total) were done. Before treatment, and after the last treatment, we measured waist circumference, hip circumference, waist hip ratio, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio, visceral fat area, free fat mass, body fat mass and skeletal muscle mass. We also measured the subcutaneous temperature of the abdomen($CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$, $CV_6$) by using digital infrared thermal imaging(DITI). Results : In this study, significant reductions were shown in waist circumference, hip circumference, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio and body fat mass. There were no significant differences in waist hip ratio, free fat mass or skeletal muscle mass. There were also significant increases of the subcutaneous temperature on $CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$. Conclusions : From the above results, electroacupuncture combined with magnetic acupuncture might be an effective treatment for abdominal obesity.

Objectives : This cross-sectional study aimed to quantify the relationship between the bone mineral density at the os calcis and the body mass composition in healthy children. Methods : The areal bone mineral density was measured at the os calcis with peripheral dual energy X-ray absorptiometry. The fat free mass, fat mass and percentage fat mass were measured using bioelectric impedance, in 237 Korean children, aged 9 to 12 years. The sexual maturity was determined by self assessment, using standardized series of the 5 Tanner stage drawings, accompanied by explanatory text. Results : From multiple linear regression models, adjusted for age, sexual maturity and height, the fat free mass was found to be the best predictor of the calcaneal bone mineral density in both sexes. About 15 and 20% variabilities were found in the calcaneal bone mineral densities of the boys and girls, respectively, which can be explained by the fat free mass. After weight adjustment, the percentage fat mass was negatively associated with the calcaneal bone mineral density in both sexes. Conclusions : The findings of this study suggest that the fat free mass, among the body compositions, is the major determinant of bone mineral density at the os calcis in Korean children aged 9 to 12 years. Obesity, defined as the percentage fat mass, is assumed to have a negative effect on the calcaneal bone density in children of the same weight.

Object : Waist circumference(WC), waist-hip ratio(WHR), waist-stature ratio(WSR), and body mass index(BMI) are commonly used for evaluating obesity. This Research were done to determine what is more sensitive obesity indexes(WC, WHR, WSR, BMI) Correlated with body composition such as body fat mass, body fat(%), visceral fat area, and fat free mass. And what is more sensitively correlated obesity indexes with % changes of body composition during weight reduction treatment. Methods : This clinical retrospective research were carried out 127 cases of female obese outpatients with weight reduction treatment during 1 month. Bioelectrical impedence analysis(for body composition) and body size(for anthropometric obesity indexes) were estimated in pre-treatment and post-treatment to evaluate the obesity indexes. Pearson correlation coefficients were used to select useful obesity index. Result & Conclusion : BMI is useful index for diagnosis and evaluation of obesity. WSR is sensitively correlated with visceral fat area and body fat(%). So, WSR is useful index for evaluating abdominal obesity and risk factors of metabolic syndrome. WC is correlated with both body fat mass and fat free mass. WHR is not optimal for diagnosis and evaluation of obesity.

To study the correlation with increasing body fat mass for the Standard Guideline for Korean Dietary Life, a nationwide, cross-sectional survey was performed with 178 male college students in december 2005. Among the student subjects, 76 were analyzed for body protein mass, body mineral mass, body fat mass, percent body fat, waist-hip ratio(WHR), body mass index(BMI) and obesity degree using Inbody 3.0(Biospace Co, Seoul, Korea). Body protein mass was at a high level of 92.1%, body mineral mass was at a low level of 94.7%. Body fat mass was at a high level of 28.9%, percent body fat was at a high level of 37.3%, WHR was at a high level of 31.6%, and obesity degree was at a high level of 38.2%, BMI was at a high level of 24.3% and BMR was observed at a high level of 41.8%. WHR was correlated with '7. Prepare food proper amount sanitarily.' and obesity degree, while BMl was were correlated with '4. Increase movement and eat proper amount.' positively. BMR was correlated with '6. Enjoy 3 meal a day regularly.' ArmCircle was correlated with '4. Increase movement and eat proper amount.' and fitness score was corrected with '4. Increase movement and eat proper amount', and '8. Enjoy Korean rice food style.' positively. Body protein mass and body mineral mass were negatively correlated with fruit, ArmCircle was positively correlated with fish, obesity degree was positively correlated with soup and BMI and ArmCircle were positively correlated with sweet. '8. Enjoy Korean rice food style.' was negatively significantly correlated with overweight, over percentage body fat, obesity degree > 120 and BMI. Male students were not practicing the Standard Guideline for Korean Dietary Life well with an average score of 37.7%. However, male students who are within the normal range of body composition analysis value have to notice that over range of weight, protein, percentage body fat, WHI and obesity degree was observed above average score of 30%.

Background: A reasonable weight reduction is to reduce fat-body mass while preserving free-fat mass. Recently, many people in Korea have been trying reckless diet therapy for weight reduction by low calory and protein diets, which gave rise to many side effects consequently. For reasonable weight reduction, this study was undertaken to investigate the influential diet factors that change body composition during short-term low calory diet. Methods: 26 healthy obese women aged 23-27 years whose BMI was greater than 24volunteered for the 6 week diet therapy from January to April in 2003. All subjects were instructed to eat approximately 1200kca1/day and write dietary diary. In the beginning of the study, the 3rd week and the 6th week, subjects' body weight and fat body weight were measured by BlA. In the 6th week, the analysis of dietary diary was conducted. Results : There was significant positive correlation between protein intake per ideal bodyweight in the first 3 weeks and free fat mass increase in the later 3 weeks (P<0.05). At the same time, fat intake in the first 3 weeks had positive correlation with free fat mass in the second 3 weeks, too(P<0.05). But, we could not find any significant values that had effect on free fat mass increase in multiple regression analysis. Conclusion: The protein intake in the first 3 weeks helps preserve fat free mass in the later 3 weeks, and has positive effects.

This study has the purpose to examine the effects of stone massage therapy on abdominal obesity reduction. 10 sessions for 5 weeks two times a week of stone massage therapy were offered to 43 adult females who were 40s through 70s with 27% or more of body fat and the results were analyzed. The body composition like body fat mass, fat free mass, weight and skeletal muscular mass etc and the degrees of obesity like body fat ratio abdominal fat ratio were measured and analyzed before and after stone massage therapy. The results are as follows: First, the subjects were obese body type and stone massage therapy produced positive effects with body fat mass, fat free mass, weight and BMI value slightly less than before the therapy. Second, as the average values of body fat ratio and waist hip ratio of subject were significantly different statistically before and after the therapy, stone massage therapy was found to be effective in reducing abdominal obesity. Third, as for the change of waist hip ratio, the therapy was found to be effective in reducing waist hip ratio that 40s decreased insignificantly after the therapy, and 50s and 60s significantly at p<0.05 level respectively from 0.92 to 0.90 and from 0.93 to 0.92. In conclusion, the results of this study indicated that stone massage therapy has positive effects on abdominal obesity reduction, and can contribute to healthy life and well-being culture.

The prevalence of diabetes has increased to 8% of population. Unlike type 2 diabetes in the western countries, Korean diabetic patients are nonobese and have low serum insulin levels. As the increased prevalence of diabetes and the peculiar characteristics may be related to dietary fat contents, we determined their effects on insulin resistance, insulin secretion and pancreatic $\beta-cell$ mass in 90% pancreatectomized (Px) diabetic rats in the present study. The rats were provided with low fat diet (LF, 10 energy% fat), moderate fat diet (MF, 25 energy% fat) and high fat diet (HF, 40 energy% fat) for 6 months. HF increased body weight and epidydimal fat pads parallel with increased food intake compared to LF and MF. Fasting serum glucose and insulin levels and homeostasis model assessment of insulin resistance were higher in HF, compared to LF and MF, indicating that HF increased insulin resistance. Rats fed LF and MF diets reduced insulin resistance, but only rats fed MF improved pancreatic $\beta-cell$ mass and insulin secretion capacity, measured by hyperglycemic clamp and in situ pancreatic perfusion. LF had low insulin secretion capacity and pancreatic $\beta-cell$ mass, indicating the increased possibility of diabetic prevalence and progression. MF increased $\beta-cell$ mass by stimulating $\beta-cell$ proliferation and neogenesis and reducing $\beta-cell$ apoptosis. In conclusion, MF is effective for the prevention of prevalence and progression of diabetes.

The aim of this study was to investigate influence of body build on body composition, energy metabolic state and insulin concentration of blood. 29 male athletes and 36 male non-athletic students were recruited for the study. Anthropometry including chest depth and breadth, fat mass, fat fee mass, tricep skinfold thickness were measured. fasting glucose, lactate, triglyceride, fee fatty acid, and insulin concentration in serum were measured . Body build was assessed using metric index, which calculated by regression equations of Mohr and Greil. The athletic and non-athletic students were allocated to 3 body build, that is leptomorph, mesomorph, and pyknomorph. Resting metabolic rate was calculated. Respiratory quotient was determined through ratio of measured VO$_2$, and V$CO_2$. Most non-athletes have a leptomorphic body build, in contrast to athletes mesomorphic type. The body build type influenced body composition differently between non-athletic group and athletic group. Weight, body mass index, body fat mass and fat mass proportion (%), and fat-free mass increased from leptomorph to pyknormorph in non-athletic group. Pyknormorphic athletes have a significant higher body mass index, fat mass, fat free mass than other body build type. Serum glucose, triglyceride, lactate, insulin showed significant differences only in non-athletic group between leptomorph and mesomorph. RMR increased significantly from leptomorph to mesomorph in non-athletes. There was no significant difference of RQ among 3 body build types in both athletes and non-athletes. This study gives a coherent data on body build and body composition for athletes and non-athletes students. The influence of body builds on energy metabolic status of serum was different between athletes and non-athletes.

Purpose: This study was performed to investigate effects of behavior modification on obesity index, skinfold thickness, body fat, serum lipids, serum leptin in obese elementary school children. Method: Forty seven students were selected from two elementary schools. Twenty four children in one school were assigned to experimental group and twenty three children in another school were assigned to control group. Experimental group was received 60～70 minutes of behavior modification once a week for 8 weeks. Result: Obesity index of the experimental group was significantly decreased after behavior modification. But there was no significant difference between two groups. The increase of skin fold thickness was significantly low in the experimental group compared to the control group. Percentage of body fat and fat mass were significantly decreased in the experimental group. Fat free mass was significantly increased in the experimental group. HDL-C, triglyceride and serum leptin between the experimental group and control group showed no significant difference. Conclusion: These results indicate that behavior modification is effective in decreasing percentage of body fat and fat mass, in less increasing skinfold thickness and in increasing fat free mass. In conclusion, behavior modification can be used as effective strategy for managing obesity in elementary school children.
