Objectives This study was performed to find out the characters about distribution of abdominal fat(especially superficial and deep subcutaneous fat) in obese premenopausal Korean women. Methods 39 obese premenopausal women were recruited in 2008. Anthropometry and body impedance analysis have been done and abdominal fat distribution had been assessed by computed tomography scan at the level of L4-5. Blood test and questionnaires about depression, eating attitude and physical activity were underwent. Result Abdominal total fat area, subcutaneous fat area including superficial and deep were significantly correlated with anthropometry and BIA result while visceral fat was correlated only with age and waist circumference. In blood profile, only visceral fat area was correlated with HDL cholesterol and triglyceride. And there were no correlation among questionnaires and abdominal fat. There were no difference between superficial and deep subcutaneous fat. Conclusion Abdominal subcutaneous fat including superficial and deep did not have any correlation with heart risk factor. superficial and deep subcutaneous fat had no differences with each other and they did not show any correlation with visceral fat in obese perimenopausal Korean women.

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.

Purpose: The aim of this study is to evaluate the relationship between abdominal subcutaneous fat thickness measured by ultrasonography (US) and serum lipid profile and liver transaminases in obese children. Methods: One hundred and sixty-six children diagnosed with obesity from May 2001 to December 2013 were included in this study. Data on serum lipid profile and liver transaminases were collected from clinical records. Abdominal subcutaneous fat thickness and grade of hepatic steatosis were evaluated by US. Results: Of the 166 children, 107 were diagnosed with hepatic steatosis by US, 46 with grade I, 56 with grade II, and five children with grade III. According to the grade of hepatic steasosis, the average values of midline abdominal subcutaneous fat thickness and right flank abdominal subcutaneous fat thickness measured $2.9{\pm}0.8cm$ and $1.9{\pm}0.7cm$ in the normal group, $3.3{\pm}0.8cm$ and $2.0{\pm}0.7cm$ in grade I, $3.8{\pm}0.8cm$ and $2.3{\pm}0.8cm$ in grade II, and $4.1{\pm}0.8cm$ and $2.8{\pm}1.4cm$ in grade III, respectively. Abdominal subcutaneous fat thickness correlated with grade of hepatic steatosis (p<0.01). In addition, abdominal subcutaneous fat thickness correlated with concentration of serum lipids and liver transaminases in the age group of 12-14 years (p<0.01). Conclusion: Abdominal subcutaneous fat thickness measured by US can be used as a reliable predictor of possible hyperlipidemia and steatohepatitis in children, especially during the adolescent stage.

Background Rectus abdominis muscle and abdominal subcutaneous fat tissue are useful for reconstruction of the chest wall, and abdominal, vaginal, and perianal defects. Thus, preoperative evaluation of rectus abdominis muscle and abdominal subcutaneous fat tissue is important. This is a retrospective study that measured the thickness of rectus abdominis muscle and abdominal subcutaneous fat tissue using computed tomography (CT) and analyzed the correlation with the patients' age, gestational history, history of laparotomy, and body mass index (BMI). Methods A total of 545 adult women were studied. Rectus abdominis muscle and abdominal subcutaneous fat thicknesses were measured with abdominopelvic CT. The results were analyzed to determine if the thickness of the rectus abdominis muscle or subcutaneous fat tissue was significantly correlated with age, number of pregnancies, history of laparotomy, and BMI. Results Rectus abdominis muscle thicknesses were 9.58 mm (right) and 9.73 mm (left) at the xiphoid level and 10.26 mm (right) and 10.26 mm (left) at the umbilicus level. Subcutaneous fat thicknesses were 24.31 mm (right) and 23.39 mm (left). Rectus abdominismuscle thickness decreased with age and pregnancy. History of laparotomy had a significant negative correlation with rectus abdominis muscle thickness at the xiphoid level. Abdominal subcutaneous fat thickness had no correlation with age, number of pregnancies, or history of laparotomy. Conclusions Age, gestational history, and history of laparotomy influenced rectus abdominis muscle thickness but did not influence abdominal subcutaneous fat thickness. These results are clinically valuable for planning a rectus abdominis muscle flap and safe elevation of muscle flap.

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.

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.

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.

Truncal obesity associated with insulin resistance and metabolic syndrome increase the likelihood of hypertension, various cardiovascular diseases, hyperlipidemia and coronary heart diseases. International Diabetes Federation (IDF) experts recognized that it is necessary to develop the simple diagnostic tool which is applicable to diagnose truncal obesity worldwide, and proposed the method using a waist circumference but there is a limit to estimate subcutaneous fat distribution. However, waist line is also influenced by total fat capacity less than the intra abdominal fat. The more having severe obesity, the more correlation coefficient between waist line and intra abdominal fat is low. Therefore, this thesis defines a new abdominal impedance measurement position and impedance-index to analysis central obesity. This proposes the new model to estimate abdominal obesity using the abdominal impedance-index and CT images acquired fro 160 Korean subjects. The proposed model shows that the abdominal fat distribution has a higher correlation than waist line. (Adj R2=0.809, 0.667 and 0.687 with abdominal fat area, visceral fat area and subcutaneous fat area respectively).

The purpose of this study was to evaluate how much effect to accuracy when measuring abdominal fat by Computed Tomography (CT) under different respiration movements. The study volunteer composed of 66 normal adults ($50.4{\pm}11.2$ years, 33 males, 33 females). We measured their obesity by using Broca index, body mass index (BMI) and CT and have investigated the correlation. The CT scanning for the obesity measurement have done in two ways, one was done in stopping breath after exhaling and the other was holding a breath after inhaling. The results showed no statistically significant difference among the three measuring techniques. And, the error in two ways of inhaling and exhaling was showed 24.2% of volunteers. The two ways of respiration movements made different result in visceral fat area (P = 0.044), subcutaneous fat area (P = 0.636) and abdominal obesity value (P = 0.012). This study demonstrates that the two ways of respiration movements when scanning CT makes change in accuracy in visceral fat area, and in abdominal obesity quantitative measure. Therefore, our study suggests that CT should take twice in two ways while a patient stops breath after exhaling and holds a breath after inhaling when measuring abdominal obesity using CT equipments.
