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.

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.

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.

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.

This study was conducted to analyze the characteristics of women's body somatotypes by direct measurements. Through the classification of degree of obesity and silhouette, women in their 20s who have a great interest in body somatotype can grasp their real somatotype and recognize their obesity rate and silhouette easily. The results are as follows: 1. Average sizes of subjects for this study were: height 160.3cm, weight 52.2kg, bust 83.7cm, waist 65.7cm, hips 91.1cm. And average values of each body mass index were: BMI 20.3, Rohrer Index 1.27, Vervaeck Index 84.8. 2. For the BMI value, the Average Numeric Index of normal somatotype was the highest, 76.9%. The Rohrer Index of underweight somatotype was 34.3% and the Average Numeric Index was 1.12. In the Vervaeck Index, underweight somatotype was 35.7%, and the average Numeric Index was 79.1, while the overweight somatotype was 7.4% of the Vervaeck Index and 100.8 of the Average Numeric Index. So the index which had the largest range of normal values from the same subjects, was the BMI, then the Rohrer Index, and finally, the Vervaeck Index in that order. 3. In the result of sorting bodies with silhouettes, when drop value were used to sort, N type (normal somatotype) was 69.4%, H type (one has similar sizes in waist size and hips) was 20.4% and A type (one has big hips) was 10.2% in that order. Among people in their early 20s, A type was 12.1%. H type was high, 22.8%, among women in their late 20s. When Sinozaki's method of classifying body types was used, ideal somatotype was 86.6%, A type was 7.4%, I type was 5.6% and X type was 0.5%. Women in their late 20s showed higher rates of ideal somatotype, the rates of A type and I type were lower than women in their early 20s.

The specific purpose was to determine the effect of walking on the body composition and hematological index of hemodialysis patients in order to confirm the relationship between activity and health level of hemodialysis patients. The research method is a cross-sectional descriptive survey conducted in hemodialysis patients.The subjects were 66 hemodialysis patients undergoing hemodialysis treatment in B city. As a result of the study, walking was decreased in hemodialysis patients, and there was a difference in hematological index according to walking, but there was no difference in body composition. As body weight increased, skeletal mass, body fat mass, body mass index, abdominal fat percentage, basal metabolism, and protein increased, but total cholesterol and high-density cholesterol decreased. This study proposes to expand the number of subjects of hemodialysis patients to investigate by adding nutritional intake in addition to walking, body composition and hematological index.

The purpose of this study was to determine the body weight control, food habits and nutrient intakes according to the obese index in male middle school students. This study was carried out through questionnaires and measurement by body fat analyzer (Inbody 4.0). The subjects were 275 male middle school students in Iksan. Chonbuk province. The average age, height, weight, and BMI of the subjects were 14.4 years old, 167.8 cm, 60.2 kg and $21.3kg/m^2$, respectively. Seventeen point one percent of the subjects were the underweight group, 47.6% were the normalweight group, and 35.3% were the overweight group by the classification of the Korean Pediatrics Society standard. Body fat of underweight, normalweight, and overweight were 16.1%, 19.0%, and 26.6%, respectively. Thirty one point nine percent of underweight, 39.7% of normalweight. and 31.9% of overweight had misperceptions of their weight (p<0.001). Sixty two point two percent of the males were dissatisfied with their body weight, and 55.3% of the whole tried to reduce their body weights. Even though they were normalweight, half of them dissatisfied with their weight. The source of weight control method was friends and family, TV radio, Internet, and school nutrition education, in order. The subjects exercised 3.4 days per week, 70.2 minutes per day, but it was not different significantly by the obese index. Forty percent of the subjects had meals fast, 58.5% of them have biased food habits even if they didn't differ by the obese index. Activity rate was different by the obese index significantly (p < 0.05), the number of severe activity was most in underweight. In conclusion, nutrition education programs should contain the necessity of normalweight, and regularity of lift habits and activities for energy expenditure in overweight students. It made them to recognize their weight correctly, establish healthy body images, and raise the ability to promote health and improve nutritional status.

Background: The purpose of this study was to identify weight control behavior according to body mass index and perception of body-image, and factors that affect weight control behavior in female college students. Methods: A convenience sample of 276 female college students agreed to complete a questionnaire. Data were collected from October 5 to October 15, 2009. The data were analyzed using SPSS win 18.0 program with descriptive statistics, Chi-square test and Logistic regression. Results: According to preferred body type, 86.9% of the students who preferred slim, 13.3% who preferred their own body type, and 4.2% who preferred chubby reported using weight control behavior. For weight control behavior according to satisfaction with body type, 82.9% of the students who were dissatisfied with their body type and 52.8% who were satisfied practiced weight control behavior. Variables influencing weight control behavior were body mass index (underweight OR 1.37, p=.050), cognition of the body (chubby/fat OR 2.68, p=.047), and preferred body type (slim OR 1.29, p=.006). Conclusion: The results of this study indicate that, health providers need to educate female college students about appropriate body image and weight control behavior. Also, more studies are needed to identify other factor influencing weight control behaviors.
