The purpose of this study is to investigate the differences in body fat distribution between obese boys and girls in high school and the relationship between the precent of body fat and the Broca Index. The survey of data was conducted from November 3rd to the 11th in 1997. The data were analyzed by the use of a mean, standard deviation and a Pearson's correlation coefficient. Measurements of the percentage of body fat and lean body mass were made by a Bioelectrical Impedence while height, weigh and the Broca index were measured by a fatness measuring system. First, measurements of height, weight and the Broca index were made by a fatness measuring system on 1,125 1st year students and 1,076 2nd year students. The result of measurements, 216 obese boys and 100 obese girls appeared to have above 10% of the Broca index. The result of this study can be summarized as follows: 1) Obese boys and girls were grouped by the level of the Broca index as follows: boys, 110-less than 120 60.0%, 120-less than 130 20.8%, 130-less than 140 11.1%, above 140 7.4%. ; girls, 110-less than 120 44.4%, 120-less than 130 32.0%, 130-less than 140 13.0%, above 140 11.0%. 2) Obese boys and girls were grouped by level of the percentage of body fat by Bioelectrical Impedence as follows: boys, less than 20% 5%, 20%-less than 25% 34.7%, above 25% 33.8% ; girls. less than 25% 15.0%, 25%-less than 30% 43.0%, above 30% 42.0%. 3) In obese boys the Broca index score appeared to be positively related to body weight(r = .741, p<.001), the percent of body fat(r=.604, p<.001), lean body mass(r=.375, p<.001), body fluid(r=.445, p<.001l). On the other hand the percent of body fat was not a significant correlation of lean body mass (r= -.074), body fluid(r= -.073). 4) In obese girls, the Broca index score appeared to be positively related to body weight(r= .693, p<.001), the percent of body fat(r=.645, p<.001), lean body mass(r=.531, p<.001), body fluid(r=.532, p<.01), and the percent of body weight score appeared to be positively related to lean body mass(r=.206, p<.01), body fluid(r=.207, p<.01).

Bone mass accretion during puberty appears to be critical in the development of peak bone mass. Although bone density of females in Korea has been studied, only a few studies have related bone mass with anthropometric patterns or puberty in the pubescent girls. This study was conducted as part of a study of major determinants of bone development during puberty. Subjects were aged 14∼16 yr(mean 14.97), and had no history of disorders or dedication use likely to influence bone or calcium metabolism. Bone mineral density and content were measured by dual energy X-ray absorptiometry using a Lunar DPX+Scanner (Lunar Madison, WI). Also, total body fat, and total lean body mass were assessed using a Lunar DPX dual-energy X-ray absorptiometer, Pubertal status was assessed according to the Marshall and Tanner guidelines. Serum levels of osteocalcin was measured by RIA using a commercial kit assay. Skinfold measurements were taken with a skinfold caliper(Lange Caliper, USA). Data were analyzed using the regression and GLM procedure of the statistical package SAS. The results indicated that the observed means for lumbar spine BMD and femoral BMD correspond to approximately 91% and 96% of the means for young adult females, respec tively. All subjects were menarchal, with the majority being in the middle to end stages of pubertal development. Total body BMD was positively related to fat mass(P<0.001), lean body mass and time since menarche, and negatively related to urine pyridinoline, serum alkaline phosphatase and osteocalcin. The data indicate that girls who reported lower age for menarche had significantly higher bone densities than girls who reported higher age for menarche. Attaining peak skeletal bone mass during puberty may reduce the incidence of osteoporosis in later life. this finding suggests that early menarche may augment peak bone mass, influencing the extent of bone loss later in adulthood. The results suggest that good nutrition in childhood appears to be needed not for growth and development, but possibly also to assure an optimal peak of bone mass and thus greater latitude for the maintenance or skeletal integrity in the face of bone losses. Troeps skinfold thickness was a better predictor of total BMD and total BMC than was any other skinfold thickness. The study did not find a relationship between total BMD and body fat %, but total fat was significantly positively related to total BMD(r=0.49) and total BMC(r=0.60). It supports earlier report that there was a significant correlation between TBMD and body weight. Conclusively, total fat, lean body mass and pubertal development could influence BMD in pubescent girls. Clearly, longitudinal studies are required to assess the effect of puberty on peak bone mass, and to define further the potential determinants of peak bone mass.

Purpose : This study was conducted to assess the usefulness of fat-free mass index (FFMI) and fat mass index (FMI) as novel expression methods of body composition in children. Methods : A total of 466 Second grade students-248 boys and 218 girls- from all elementary schools the Gwacheon City underwent anthropometric measures including bioelectrical impedance analysis (BIA) and biochemical tests. The correlation coefficients between obesity indices, including FMI and FFMI, and metabolic risk factors, were assessed. Metabolic risk factors of children with increased FMI were compared with those of children with normal FMI. We compared FMI and FFMI percentile distribution between this study's subjects and the subjects of the Fukuoka body composition study. Results : FMI was lower and FFMI was higher in this study's subjects compared to the subjects of the Fukuoka body composition study. FMI was correlated with other obesity indices and several metabolic risk factors. Metabolic risk was higher in children with increased FMI than in children with normal FMI. Conclusion : FMI and FFMI were useful indicators in comparing difference of body composition among children that had different body size and growth. High FMI was related to increase of metabolic risk in children.

This study was carried out to evaluate the associations between lifestyles and Body Mass Index in a group of 349 male and 65 female medical students, ages 17 to 31 years. 20.0% of male students and 3.1% of female students showed the over weight in the classification of obesity by Japan Society for Study of Obesity. There was no statistically significance in the comparison of the height, body weight, body mass index, obesity index and body fat(%) according to grade in both sexes. But male students showed increasing tendency of waist-hip ratio with grade. According to obesity category, there was significant difference in the comparison of body weight, body mass index, obesity index, waist-hip ratio and body fat(%), but height. Body mass index was positively related with waist-hip ratio(r=0.6150, p=0.0001) and fat(%)(r=0.5101, p=0.0001) in males and waist-hip ratio (r=0.4734, p=0.001) and fat(%)(r=0.4522, p=0.002) in females. This study provides an opportunity to further examine the relationship of sociddemographic factors and health behaviors to obesity, and suggest the basic concept to match the obesity study to general epidemiological cohort studies for controlling of chronic adult diseases.

Body fat distribution in patients with Prader-Willi syndrome (PWS) is characterized by reduce lean body mass (LBM), increased total body fat mass (FM), and lower percentage of visceral adipose tissue (VAT). Individuals with PWS seem to have a lower risk for insulin resistance with high levels of adiponectin, an anti-atherogenic adipocytokine that is decreased in visceral fat hypertrophy subjects compared to simple obese subjects, both in children and in adults. The mechanism of the reduction in visceral adiposity in PWS is still unclear. It might be related to qualitative intrinsic characteristics of adipocyte or novel genetic influences on the control of fat distribution. However, obesity remains a critical problem, and obesity status plays a crucial role in individual metabolic risk clustering and development of metabolic syndrome (Mets) in PWS children and adults. Long-term growth hormone (GH) treatment after cessation of skeletal growth improved body composition, with an increase in lean body mass and a reduction in total body fat and subcutaneous and visceral fat in PWS adults. Thus, the role of GH is important after childhood because it might attenuate obesity and Mets in PWS adult by adipocyte modification.

Objectives The purpose of this study is to investigate the relationship between weak children and growth indices. Methods One hundred twenty-six of the first and the second grade elementary school students who didn't have to develop yet their secondary sexual characteristics answered the questionnaire. Their bone age and body composition were measured. Results 1. According to the Weak Children questionnaire analysis, respiratory problem was one of the biggest problems in the weak children group (35.7%), followed by digestive problems (23.0%), psycho-neurological problems (22.2%), neuromotor problems (9.5%), and urogenital problems (8.7%). 2. From the comparison between growth indices of weak children and that of normal children are as follows: 1) The group of children who had problem in their digestive system had lower growth indices than the normal average children group. The growth indices includes mean height, weight, total body water, protein mass, mineral mass, body fat, skeletal muscle mass, body fat percentage, body mass index (BMI), and basal metabolic rate (BMR). 2) The children who had urogenital weakness had lower mean height, RH (Recent Height), RH - MPH {Recent Height(%) - Mid-Parental Height(%)}, RUS (Radius, Ulna and Short bone) score, weight, protein mass, body fat, BMI, and visceral fat than the normal children group. 3. The results of the multiple comparisons of growth indices and weak children groups are as follows: 1) Digestive weak children were the lowest in total body water, protein mass, mineral mass, skeletal muscle mass, and basal metabolic rate. 2) Urogenital weak children were the lowest in height, RH, RH - MPH, RUS score, and weight. Conclusion These results showed that children's growth is strongly correlated to their own growth problems, especially to those children who have digestive and urogenital problems. Therefore, this may be an effective way for children growth treatment in Korean medicine to treat weak symptoms.

Purpose: The purpose of this study was to investigate body composition, blood pressure, blood lipids, and glucose according to obesity degree by body fat percentage in female university students. Methods: A total of 231 subjects were participated between July and December 2010. The anthropometric measures and blood analyzer were used. Data were analyzed using descriptive statistics, ANOVA, and Pearson's correlation coefficient with SPSS 18.0. Results: Percentage of body fat (PBF)-defined obesity had higher prevalence than body mass index (BMI)-defined obesity. Weight, BMI, PBF, fat mass, Waist to hip ratio (WHR), Systolic blood pressure (SBP), Diastolic blood pressure (DBP) in obesity group were higher than normal group and Soft lean mass and Low density lipoprotein (LDL) in obesity group were lower than normal group. There were significant correlations between PFB, SBP, DBP, Triglyceride (TC), High density lipoprotein (HDL), and LDL. Conclusion: In conclusion, when screening for obesity in female university students, body fat should be considered. It is needed to develop obesity management program according to obesity degree and to identify the effectiveness.

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.
