The patients who visited the Health Promotion Center were compared between the visceral fat area according to CT fat measurement position and the visceral fat area measured by Inbody. In the CT measurement, the visceral fat area measured at the L4-5 and CT Umbilicus positions was not different regardless of gender. In addition, there was no difference between CT visceral fat area and Inbody visceral fat area in the correlation between visceral fat area according to CT measurement position and visceral fat area measured by Inbody. The highly correlated CT measurement position were male L4-5, L5-S1, female L3-4, L4-5, L5-S1, and Umbilicus. In addition, when studying the relationship between the inbody visceral fat area and CT visceral fat area regardless of gender, it is suggested to compare the visceral fat area at the CT L4-5 position.

In the current study, the relationships between abdominal adipose tissue depots and skinfold thickness, body circumference and composition, and blood lipids and pressure were investigated in adolescent obese man. Total abdominal adipose tissue (TAT) and subcutaneous adipose tissue (SAT) were correlated with skinfold thickness. Especially subscapular skinfold was highly correlated with TAT and SAT, and it was found that chest skinfold was the only predictor for estimating visceral adipose tissue (VAT). Body circumference and body composition were associated with TAT and SAT, not VAT, and correlation coefficient of waist circumference was highest. On the other hand, body fat mass was highly correlated with TAT and SAT than %body fat and fat free mass. It was also shown that blood triglyceride concentration and systolic blood pressure were the only predictor for estimating VAT and SAT respectively.

This study was performed to compare the differences between total fat area, subcutaneous fat area and visceral fat area according to L1-S1 inter vertebral disc level in asymptomatic Korean patients with non-contrast abdominal CT scan. The location of the maximum fat ratio of the total fat area is the total fat area measured in male L2-3, L3-4, L4-5, female L4-5, and L5-S1. The location showing the maximum fat ratio of the subcutaneous fat area is the subcutaneous fat area measured in male L4-5, and the woman is the subcutaneous fat area measured in L4-5 and L5-S1. The location of the maximum fat ratio of visceral fat area was the visceral fat area measured in L1-2 and L2-3 males, and there was no difference in visceral fat area according to the measured position in females. Although abdominal fat measurement is common at the L4-5 inter vertebral disc level, fat distribution varies widely depending on nationality, race, and gender. Therefore, it is necessary to analyze through the research data which location to choose according to the research purpose, and to mention why the location is appropriate.

The purposes of this study were to observe the effects of the exercise programs which have different order of walking and resistance exercises on the composition of the abdominal fat and the blood lipid profiles of the obese college women and to provide basic materials for the development of more effective and more efficient exercise program in order to reduce and prevent obesity. Classification of group, "A" group(resistance exercise after aerobic exercise) is a group of 12 people, "B" group(resistance exercise after aerobic exercise) is a group of 12 people. To determine the abdominal fat, intestine fat area, subcutaneous fat area, ratio of intestine fat area/subcutaneous fat area were analyzed, while for the blood lipid profiles, total cholesterol, triglyceride, high density lipid protein, and low density lipid protein were analyzed. First, there was statistically significant difference in the interaction in the abdomen subcutaneous fat. In the post analysis, the Resistance first group showed significantly more reduction to confirm that there was difference according to the order of the exercises. Second, there was statistically significant difference in the interaction effects in the factor of triglyceride. In the post analysis, the Resistance first group only showed significant reduction in the triglyceride to confirm that resistance exercise followed by aerobics would be better for the reduction of the triglyceride.

Purpose : Visceral fat accumulation plays a major role in metabolic complications of obesity. It is known that nonalcoholic fatty liver in obese adults is associated with visceral fat accumulation. Body mass index(BMI) is used as the index of obesity in children. The aim of this study is to evaluate the correlation of BMI and visceral adipose tissue(VAT), and the correlation of BMI, body fat distribution, aminotransferases, and severity of fatty liver. Methods : Twenty three obese children with fatty liver diagnosed by non-contrast abdominal computed tomography(CT) were included in this study. Data on BMI, aminotransferase levels were collected from clinical records. Visceral adipose area was evaluated with CT. Results : BMI had a singnificant correlation with VAT(r=0.51719, P=0.0115). The severity of fatty liver had no significant correlations with BMI(r=-0.11938, P=0.5876), VAT(r=-0.31234, P=0.1468), aspartate aminotransferase(AST)(r=0.12729, P=0.5628) or alanine aminotransferase(ALT)(r=-0.00179, P=0.9935). Conclusion : BMI in obese children was correlated with VAT. But the severity of fatty liver cannot be assessed by BMI, VAT or aminotransferase levels.

This study was performed to examine the diet effect of green coffee bean extract on body fat reduction. Overweight/obese women (body mass index > $23\;kg/m^2$ or body fat > 27%) who were not diagnosed any type of disease were included in this study and subjects were randomly assigned to green coffee bean extract group (n = 23) or placebo group (n = 20). We measured anthropometric parameters, abdominal fat distribution by computed tomography and blood components before and after the 8-weeks intervention period. After supplementation, green coffee bean extract group showed a significant reduction of body weight (p < 0.01), body fat percent (p < 0.01), total fat area at L1 vertebra (-4.8%, p < 0.05) and visceral fat area at L4 vertebra was(-4.7%, p < 0.05). In addition, total fat area and visceral fat area at L1 vertebra decreased significantly in green coffee bean extract group compared with placebo group (p < 0.05, p < 0.05 respectively). The result of present study demonstrated that the supplementation of green coffee bean extract for 8 weeks can give beneficial effects on body fat reduction and visceral fat accumulation.

The aim of this study was to analyze the effects of aerobic exercise on the blood lipids, leptin, ghrelin, and HOMA-IR factors in obese postmenopausal Korean women. Thirty-six healthy postmenopausal women (mean age, $54.47{\pm}2.50$ years) with >32 % body fat were assigned randomly to an aerobic exercise group (n = 18) or to a "no exercise" control group (n = 18). The subjects' body composition, blood lipid, leptin, ghrelin levels, and HOMA-IR were measured before and after a 16-week line-dancing program. The exercise group showed a significant decrease in body weight, percent body fat, body mass index, visceral fat area, leptin, insulin, glucose, HOMA-IR, total cholesterol, triglycerides, apolipoprotein B, low-density lipoprotein cholesterol, and systolic and diastolic blood pressure. In addition, this group exhibited a significant increase in the apolipoprotein A-I, ghrelin, and high-density lipoprotein cholesterol levels. The energy metabolic factors that influenced the visceral fat included ghrelin, leptin, insulin, glucose, and HOMA-IR. The t-value, which determined the statistical significance of the independent variables, was significant for ghrelin, glucose, insulin, and HOMA-IR (p < 0.05). Regular and continuous aerobic exercise (e.g., line dancing) effectively improved the body composition, visceral fat, serum blood lipids, leptin, ghrelin, and HOMA-IR factors in obese postmenopausal Korean women.

The purpose of this study was to predict abdominal obesity with 3-Dimensional computed tomography (3D CT) measurements of kidneys by analyzing the correlation between kidney sizes and abdominal obesity level. The subjects were 178 healthy adults without underlying diseases who had a comprehensive health examination at the Health Medical Center of Jesus Hospital in Jeonju. Abdominal obesity was measured by CT cross-sectional image at the level of the umbilicus and divided into visceral fat area, subcutaneous fat area, visceral fat/total fat ratio. The average comparison of kidney sizes classified according to abdominal obesity were performed through one-way analysis of variance (ANOVA) and Scheffe test. Pearson correlation analysis was performed to correlate all measurement values. The results of kidney size ANOVA analysis according to abdominal obesity were as follows. The means of kidney measurements according to visceral fat classification were significantly different in all kidney measurements (p<0.05). And in case of subcutaneous fat classification, the means of kidney measurements by 3D CT of the severe obesity group were significantly different in the right kidney width (p<0.05). In case of visceral fat area/total fat area ratio, the means of kidney measurements by 3D CT of the severe obesity group were significantly different in both kidneys width (p<0.05). Pearson correlation between kidneys measurements and CT abdominal obesity showed that visceral fat area had the highest correlation with the left kidney width measured by 3D CT (r=0.467) and subcutaneous fat area had correlation with the right kidney width measured by 3D CT (r=0.249). The visceral fat area/total fat area ratio had correlation with the left kidney width measured by 3D CT (r=0.291).
