Objectives : The purpose of this study was to determine what is useful index of abdominal visceral fat area among Korean obese adolescents. Methods : 35 obese adolescents who had visited Kirin Oriental Hospital from August 2004 to May 2006 were included in the study. Weight, height, waist and hip circumferences were measured. Abdominal visceral fat areas at L4-5 level were measured by computed tomography. The subjects were divided into two groups, according to sex. In each group, we investigated the correlation among waist circumference, waist/hip ratio, waist/height ratio, obesity degree and abdominal visceral fat area and evaluated that which one of these kinds of indices is the most useful predictor for visceral fat area in Korean obese adolescents. Results : There were significant correlation between waist circumference, waist/hip ratio, waist/height ratio and obesity index in both group. In boys waist/hip ratio had correlation with abdominal visceral fat area and in girls obesity index had significant correlation with abdominal visceral fat area. Conclusions : Our study suggests that waist/hip ratio in boys, obesity degree in girls can be a relatively good parameter for predicting abdominal visceral fat area.

Objectives : This study was performed to assess the effect onf abdominal obesity treatment on changes in abdominal subcutaneous and visceral fat. Methods : The study was conducted on 61 abdominally obese patients (13 men and 48 women). Measures of body weight, waist circumference, abdominal subcutaneous and visceral fat area by CT scan, and V/S ratio (Viscero-subcutaneous fat ratio) were acquired before and after Kirindiet therapy. Paired t-test and Wilcoxon signed rank tests were used to est the effects of teatment. Results : Following a mean of 68 days of treatment, waist circumference (-15%), abdominal total fat (-40%), subcutaneous fat (-37.9%), visceral fat (-47.8%) and V/S ratio (-11.1%) were significantly reduced (p<0.05). The change in V/S ratio in female patients was not statistically significant (p=0.491) whereas the change in the V/S ratio in male patients was significant indicating a greater loss of visceral fat (p=0.017). Please check that my changes reflect what the study found Conclusions : The reduction in visceral fat was greater than for subcutaneous fat in male patients but not for female patients.

Objectives : This study examined search on how the obesity indices, that are largely used in clinics such as waist circumference(WC), body mass index(BMI) and waist-hip ratio(WHR), are related to the visceral fat that was measured from abdominal computed tomography(CT) and the ratio of visceral fat/subcutaneous fat. Then, two groups ware compared in order to find out which characteristics of ordinary adults relationship with the abdominal obesity. Two groups are divided as follows; ones who are obese based on the measurement of WC and the others who are obese based on the level of BMI. Methods : A group of 63 test subjects that were gathered in the oriental medical hospital of Kyung-Won university is divided into two groups; ones (n=51, general obesity; group A) who have $BMI{\geq}25$ and $WC{\geq}85$, and the others (n=12, abdominal obesity; group B) who have BMI<25 and $WC{\geq}85$. Then, each group's obesity indices, abdominal CT, lipid level, glucose, adiponectin, leptin and C-reactive protein(CRP) are compared. In addition, subjects are again divided into two to examine the characteristics; ones (n=14, visceral obesity; group C) with visceral obesity based on the ratio between visceral fat and subcutaneous fat measured through abdominal CT, and the others (n=38, non-visceral obesity; group D) who are obese but not viscerally obese. Results & Conclusions : As a measurement that applies abdominal visceral fat and subcutaneous fat, BMI and WC can be considered as an appropriate obesity index while WHR cannot appropriately apply the abdominal fat amount. Moreover, the study indicates that abdominal obesity group based on the ratio of visceral fat/subcutaneous fat has more significant difference than the abdominal obesity group based on the WC in case of blood lipid index.

Objectives: Considering that homeothermy is a major component of metabolic rate, body temperature might play a role in the pathophysiology of obesity. This study aimed to determine the relationship between abdominal fat distribution and abdominal temperature in Korean, premenopausal, obese women. Methods: Weight and height were measured in 26 premenopausal, obese women to calculate body mass index (BMI). Obesity was defined as a $BMI{\geq}25kg/m^2$. Waist circumference (WC) was also measured as well as abdominal fat by computed tomography (CT) and abdominal temperature by digital infrared thermographic imaging (DITI). Results: Visceral abdominal fat area was found to have a significant negative correlation with the temperature of Guanyuan (CV4, lower abdomen acupoint). We also found the visceral-subcutaneous fat ratio had a significant negative correlation with the temperature of CV4 and Right Tianshu (RST25, lateral navel acupoint). Only visceral fat and its ratio to subcutaneous fat had a significant correlation with abdominal temperature. Subcutaneous fat area and total fat area were not correlated with abdominal temperature. Conclusions: This study suggests that abdominal visceral fat has a significant negative correlation with abdominal temperature. Further study is needed to uncover the relationship between abdominal fat distribution and temperature regulation in obese individuals and to define the role of body temperature in the pathogenesis of obesity.

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 purpose of this study is to analyse the effects of obesity management program in food attitude and food habit, body composition(body fat ratio, body fat weight, lean body mass, total body water), abdominal girth(waist, hip, thigh), and serum lipid level(cholesterol, low density lipoprotein, triglyceride, phospholipid, NE fatty acid, high density lipoprotein) of middle aged women. Data for the study were collected from July 4 to August 25, 2000. The study objects were 20 middle aged women(10 controls and 10 experimental objects) from 40 to 50 years old who had body fat ratio more than $30\%$ and waist girth more than 80cm. The results were as follows: 1. Similarity test between experimental group and control group processed by serum HDL level showed the significant difference(t=3.25, p=0.004), but that processed by age, body weight, body fat ratio, body fat weight, lean body mass, total body water, waist girth, hip girth, thigh girth, cholesterol level, LDL level, triglyceride level, NE fatty acid level, food attitude and food habit score showed no significant difference(p>0.05). These findings imply that the two groups are similar in the sample distribution. 2. The effects of the abdominal obesity management program The obtained results indicate that the abdominal obesity management program in middle aged women changes the food attitude & the food habit. decreases the body fat ratio & the body fat weight and increases the lean body mass, and decreases the girth of waist & hip and the serum level of cholesterol & LDL. Therefore, it is concluded that the abdominal obesity management program can be applied for nursing intervention to decrease the body fat weight and abdominal obesity.

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.

Anthropometry, computed tomography(CT) at the umbilical level, nutrient intake, blood pressure, serum levels of lipids and lipoproteins and response of glucose, c-peptide, insulin, and free fatty acid(FFA) during oral glucose tolerance test(OGTT) were estimated on 11 normal-weight controls and 35 overweight and obese middle-agd men. The areas of total abdominal, subcutaneous and visceral were determined by CT scanning technique. Total abdominal fat area correlated the most significantly with the levels of serum lipids, lipoproteins and insulin among several obese indices. Compared with normal-weight controls, overweight and obese men with abdominal fat lower than 29000$\textrm{mm}^2$ showed an increase in waist-hip ratio, areas of total abdominal(35%), visceral and subcutaneous fat and C-peptide response area during OGTT, though age, percent ideal body weight, body mass index, % body fat, and all biochemical indices except C-peptide response area were not different between two groups. Overweight and obese men with abdominal fat greater than 29000$\textrm{mm}^2$ showed a higher values in total abdominal fat(85%), serum levels of triglyceride, total-and LDL-cholesterol, the ratio of LDL-to HDL-cholesterol, and response areas of FFA, insulin and C-peptide during OGTT than normal-weight controls. Overweight and obese men with great abdominal fat showed an increase in alcohol ingestion and percent calorie intake per total energy expenditure, compared with normal-weight controls. Our results indicate that obesity and a certain level of total abdominal fat accumulation is required to observe abnormal levels of serum lipids, lipoproteins and insulin in Korean middle-aged men. In addition, increased alcohol and calorie intake and decreased physical activity could partly explain total abdominal fat accumulation in men.

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: We compared the associations of 3 computed tomography (CT)-based abdominal adiposity indexes with non-alcoholic fatty liver disease (NAFLD) among middle-aged Korean men and women. Methods: The participants were 1366 men and 2480 women community-dwellers aged 30-64 years. Three abdominal adiposity indexes-visceral fat area (VFA), subcutaneous fat area (SFA), and visceral-to-subcutaneous fat ratio (VSR)-were calculated from abdominal CT scans. NAFLD was determined by calculating the Liver Fat Score from comorbidities and blood tests. An NAFLD prediction model that included waist circumference (WC) as a measure of abdominal adiposity was designated as the base model, to which VFA, SFA, and VSR were added in turn. The area under the receiver operating characteristic curve (AUC), integrated discrimination improvement (IDI), and net reclassification improvement (NRI) were calculated to quantify the additional predictive value of VFA, SFA, and VSR relative to WC. Results: VFA and VSR were positively associated with NAFLD in both genders. SFA was not significantly associated with NAFLD in men, but it was negatively associated in women. When VFA, SFA, and VSR were added to the WC-based NAFLD prediction model, the AUC improved by 0.013 (p<0.001), 0.001 (p=0.434), and 0.009 (p=0.007) in men and by 0.044 (p<0.001), 0.017 (p<0.001), and 0.046 (p<0.001) in women, respectively. The IDI and NRI were increased the most by VFA in men and VSR in women. Conclusions: Using CT-based abdominal adiposity indexes in addition to WC may improve the detection of NAFLD. The best predictive indicators were VFA in men and VSR in women.
