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.

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.

Purpose: This study was to examine the effect of an obesity management program on the body weight, body-mass index, and physiological index of obese female high school students. Method: Students from one school were selected as the experimental group, and students from another school as a control group so the latter group wasn't exposed to the experiment. The experimental group and the control group were each organized with 20 students. The experimental group received 60 minutes of behavior modification once a week, for eight weeks. Result: The Body weight, and Body mass-Index of the experimental group significantly decreased after the obesity management program. Total-cholesterol, T-G, and LDL-C significantly decreased and HDL-C increased in the experimental group. Total-cholesterol, T-G, LDL-C and HDL-C between the experimental group and control group showed significant differences. Conclusion: These results indicate that the obesity management program had a great effect on decreasing the body weight and body-mass index of the female obese high school students, normalizing their physiological index. In conclusion, this program turned out to be one of the safest and most effective obesity-management methods that could be applied to female high school students.

This study was done to compare the difference of obesity index(waist-hip ratio, body fat, body mass index, relative body weight), blood pressure and serum lipids in abdominal obesity and non abdominal in both men and women. Abdominal and non abdominal obesity was divided into waist-hip ratio above 0.85 in women and 0.95 in men. The subjects were 412 adults (age range 40-59), who had regular health examinations between 1996 to 1997 at the S-Hospital in Seoul. The data were analyzed using ANCOVA (for adjusted for age) and Pearson correlation coefficient. The results were as follows: 1. 39.9% of men and 42.5% of women had abdominal obesity. The average age group of abdominal obesity was 50.8 which is older than the non abdominal obesity group(48.0). 2. After they were adjusted for age, the group of men who have abdominal obesity had higher levels in body fat, body mass index, relative body weight, blood pressure, total cholesterol, LDL- cholesterol and triglyceride than the group of non abdominal obesity group. The group of women with abdominal obesity had higer levels in body fat, body mass index, relative body weight , blood pressure and triglyceride than the group of non abdominal obesity. 3. In the group of non abdominal obesity, the waist-hip ratio was significantly correlated to body fat, body mass index, relative body weight, blood pressure and serum lipids the group of abdominal obesity in men and women.

In this study, we examined chewing frequency, eating rates, and food consumption volume according to the body mass index of male and female college students. Twenty-five male college students were divided into a normal weight male group (<23 body mass index, n=14) and an obese male group (${\geq}23$ body mass index, n=11). Twenty-five female college students were divided into a normal weight female group (<23 body mass index, n=21) and an obese female group (${\geq}23$ body mass index, n=4). Subjects were provided with abundant fried rice and allowed to consume it at their own pace. Chewing frequency, total mealtime, rate of eating, consumption volume, calorie intake, and the amount of one bite were measured. There were no significant differences in chewing frequency, total mealtime, rate of eating, consumption volume, calorie intake, and the amount of one bite between the normal and obese male groups. There were also no significant differences in chewing frequency, consumption volume, calorie intake, and the amount of one bite between the normal and obese female groups. However, the obese female group had a significantly shorter mealtime and significantly higher eating rate compared with the normal group. Thus, our study suggests that females who eat a meal for a longer time may reduce their food intake, consequently inducing body weight loss.

Visual evaluation of chest radiograph images is the most practical and effective method. This study compared the Body Mass Index, waist circumference, and mAs with chest radiographs of 351 women. The Bureau of Radiological Health method was used to evaluate the image quality of chest X-ray images by anatomical and physical methods. The average age of the subjects was $30.17{\pm}4.73$ and the average waist circumference was $66.91{\pm}4.67cm$. The mean Body Mass Index value was $20.21{\pm}2.23$, the mean value of mAs was $3.04{\pm}0.78$, and the mean value of Bureau of Radiological Health was $79.83{\pm}8.45$. When the Body Mass Index value increased, waist circumference and mAs mean value increased. The mean value of Body Mass Index was statistically significant(p<0.05) in Group 4 compared to Groups 1 and 2, with increasing Body Mass Index. Exposure control of the automatic exposure control system is considered to be well performed according to body thickness or Body Mass Index at the time of chest radiography. As the Body Mass Index increases, the thickness of the body increases and the breast thickness of the woman also increases. Therefore, it is considered that the exposure amount is changed by the automatic exposure control device to affect the image quality.

Objectives The purpose of this study is to understand the correlation between spleen deficiency syndrome, body mass index (BMI) and eating habit in children and adolescents and to provide foundation of preventive care and treatment. Methods A survey was conducted with 115 children and adolescents, who were 4th, 5th and 6th grade of elementary school in Gwangju from March 2nd, 2016 to April 8th, 2016. Body mass index (BMI) was calculated using the measured height and weight. Spleen deficiency syndrome and eating habit in children and adolescents were investigated by using the Deficiency of the Spleen Questionnaire and Korean Children's Eating Behaviour Questionnaire (K-CEBQ). A data analysis was performed by using SPSS 23.0 program. Results 1. There was no statistically significant correlation between spleen deficiency syndrome and body mass index (BMI). 2. Children and adolescents with spleen deficiency syndrome were interested in food rather than avoided it. 3. There was a positive correlation between body mass index (BMI) and FR (Food responsiveness), "Food approach". The correlation between the healthy weight group and FR is statistically significant negative correlation. Conclusions Due to various limitations, it is difficult to generalize the correlation between spleen deficiency syndrome, body mass index (BMI) and eating habit in children and adolescents. Therefore additional research is necessary to confirm this study's findings.

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.

Purpose: The purpose of this study was to review the literature to explore the relationship between body mass index (BMI) and bone mineral density (BMD) in elderly using an integrative review. Methods: The keywords 'osteoporosis,' 'body mass index,' and 'bone mineral density' were used to search peer-reviewed publications through four databases. Among 1,389 searched articles, eight articles were selected after excluding those that did not meet the inclusion criteria. Results: Seven articles stated that BMI was positively associated with BMD among elderly. In the elderly, the prevalence of osteoporosis was 25-55.7% in women, and 11-13% in men. Conclusion: This study found that high BMI may be helpful to increase BMD among elderly although the mechanism was not clear. It is necessary to identify BMD and fractures in elderly according to body composition in future research.
