Background: Correlation between colorectal cancer (CRC) and abdominal obesity has been established, but there is a paucity of data on non-obese CRC patients. The aim of this study was to establish the characteristics of CRCs that occur in such patients. Materials and Methods: Consecutive CRC patients without cachexia were included. Unintended body weight loss, T4- or M1-staged CRCs, extensive lymph node involvement, or synchronous malignancy were classified as cachectic conditions. Abdominal fat volumes were measured using a multidetector CT unit with a software (Rapidia, INFINITT, Seoul, Korea). Results: Of the newly-diagnosed CRC patients, 258 non-cachectic and 88 cachectic patients were analyzed. The cancer size (p<0.001) and T stage (p<0.001) were inversely correlated with body mass index (BMI), visceral fat and subcutaneous fat volumes. Cancer size was the only independent factor related to BMI (p=0.016), visceral fat volume (p=0.002), and subcutaneous fat volume (p=0.027). In non-cachectic patients, a significant inverse correlation was found only between the cancer size and visceral fat volume (p=0.017). Conclusions: Non-obese CRC patients tend to have larger CRC lesions than their obese counterparts even under non-cachectic conditions. Such an inverse correlation between cancer size and visceral fat volume suggests that considerable CRCs are not correlated with 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.

Objectives : The purpose of this study were to evaluate the effects of oriental medical therapy on obesity and different effects according to Body Mass Index(BMI), menopause, obesity treatment experience, age, treatment period in patients. Methods : 46 patients were treated from November 2011 to April 2012 in Oriental Obesity Center, Dong-eui Medical Center. They were measured change of body compositions by bioelectrical impedance analysis every 2~3 weeks and 27 patients out of 46 were checked body compositions every 2 weeks. 46 and 27 patients were divided into two or three groups according to BMI, menopause, obesity treatment experience, age, treatment period. We compared before and after treatment body compositions. Results : Body compositions, except edema index were significantly reduced. Abdominal Visceral Fat(AVF) was significantly reduced in Obese group. Body Weight(BW), BMI, Body Fat(BF), Body Fat Percetage(BFP), Abdominal Visceral Fat Level(AVFL), Abdominal Visceral Fat(AVF), Abdominal Subcutaneous Fat(ASF) were significantly reduced in non-menopause group(43 female patients). But in 26 female patients out of 27, there were no significantly differences between groups in menopause. There were no significantly differences between groups in obesity treatment experience. But in 27 patients, BMI and AVF were significantly reduced in non-experience group and AVFL was significantly reduced in experience group. BW, BMI, BF, BFP, VAF, ASF were significantly reduced in younger age group. But in 27 patients, BW and Muscle were significantly reduced in younger age group. BMI, BF, BFP, Edema, AFVL, Abdominal Visceral Fat Area(AVFA), AVF, ASF were significantly reduced in longer treatment period group. Conclusion : The BF, BMI, BF, BFP, Muscle, AVFL, AVFA, AVF, ASF were almost decreased significantly. It resulted that the effects of oriental medical therapy in obesity was positive. And it was meaningful study to know about different effects between groups.

Object The purpose of this study is to evaluate the effect of far-infrared (FIR) therapy on weight loss. Method Thirty five participants (BMI ${\geq}25kg/m^2$) were recruited. Body weight, Waist circumference (WC), Bio Impedance Analysis (BIA), abdominal fat Computer Tomography (CT) scanning were evaluated. Results of 25 women were analyzed. Result After 6 weeks of FIR therapy, there was significant efficacy on obese women in body weight, WC, Body fat mass (BFM), and Visceral fat area (VFA). But there was no efficacy in Total fat area (TFA), and Subcutaneous fat area (SFA). Conclusion This study suggests that FIR therapy might be an effective way to promote weight and abdominal visceral fat loss in Korean obese women.

In middle-aged men, abdominal obesity has been an important risk factor of coronary artery disease (CAD) as well as a predictor of hypertension, dyslipidemia, insulin resistance and glucose intolerance. Particularly, risks from abdominal obesity increase when adipose tissue accumulates in visceral compartment. Many studies showed that weight reduction by caloric restriction improves abdominal obesity and reduces lots of cardiovascular risk factors. Testosterone treatment also results in a significant decrease in visceral fat area and normalizes endocrine metabolism. However there is no study that compare the effect of caloric restriction with that of testosterone treatment. The purpose of this study is to investigate the effect of caloric restriction and that of testosterone treatment on body fat distribution, serum lipids and glucose metabolism in male patients with CAD. Forty five middle-aged overweight-obese men with CAD participated in 12 weeks' program. They were matched with age, body weight, body mass index (BMI) and divided into three groups : control group (n = 15) , caloric restriction group (-300 kcal/day, n = 15) and testosterone treatment group (testosterone undecanoate tablets, n = 15) . After 12 weeks, control group did not have any changes in anthropometries, lipid profile, body fat distribution, glucose metabolism and hormonal status. Expectedly, caloric restriction group showed decreases in body weight, BMI, waist to hip ratio, ％ body fat. Ten percentage of total cholesterol and 23% of triglyceride in serum were also decreased. In body fat distribution, total fat areas at both L1 and L4 levels were significantly reduced in this group without reduction in muscle of thigh and calf. However, testosterone treatment group did not have any significant changes in body weight, ％ body fat, serum lipid profile and abdominal fat distribution. In conclusion, weight reduction by caloric restriction is more beneficial in body fat distribution and serum lipid level than testosterone treatment in overweight male patients with CAD. This result suggests that modest weight reduction is possible to help decrease risk factors of CAD.

Objectives : This study was performed to figure out the effects of herbal mesotherapy on abdominal fat in obese women. Methods : Forty obese women those who were diagnosed abdominal obesity had been recruited during February, 2008. They were randomly assigned experimental or control group under block-randomization. Experimental group were treated with Sobi-eum(Xiaofei-yin) injection during 6 weeks (2 times a week) and placebo group were treated with normal saline injection under same procedures. Anthropometry, body impedance analysis, fat computed tomography, blood test, and questionnaires had been administered before and after the treatment. Results : Four subjects were dropped out (voluntary give up), so 18 in experimental group and 18 in placebo group were evaluated. There were significant changes after treatments in both groups. Although no significant differences have been found in the result of anthropometry, body impedance analysis and fat computed tomography between two groups, in the experimental group, the changes of total fat area had a highly significant relationship with all part of abdominal fat. While the placebo group had highly significant relationships with subcutaneous fat area, superficial and deep subcutaneous fat area but not with visceral fat area. Conclusions : Compaired with saline group, herbal mesotheraphy Sobi-eum(Xiaofei-yin) is effective in reduction of visceral fat after adjusting TFA.

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.

목적 : 복부비만 특히 내장지방의 과잉축적은 대사증후군 발생에 밀접한 관련이 있는 것으로 알려져 있다. 따라서 내장지방의 정확한 평가는 중요하며, 초음파 측정법은 간편하고, 안전하게 내장지방을 평가할 수 있는 방법으로 보고되고 있다. 본 연구는 초음파에 의해 측정된 복부 내장지방두께와 신체계측지표 및 대사증후군 관련인자와의 연관성을 확인하고, 대사증후군 예측을 위한 내장지방두께 기준을 알아보고자 하였다. 대상 및 방법 : 2008년 1월부터 4월까지 대전 D 건강검진센터에 내원한 건강검진자 중 400명(남자 200명, 여자 200명)을 대상으로 하였다. 초음파 검사로 제대 바로 위에서 내장지방 및 피하지방두께를 측정하였고, 신체계 측지표로 체질량지수, 허리둘레, 허리둘레/키 비를 측정하였으며, 대사증후군 관련인자로 혈압, 고밀도콜레스테롤(HDL-C), 중성지방(TG), 공복혈당(FBS)을 측정하였다. 초음파 측정지표와 신체계측지표 및 대사증후군 관련인자와의 상관관계를 분석하였으며, ROC곡선을 이용하여 대사증후군 예측을 위한 내장지방두께를 산출하였다. 결과 : 내장지방두께는 허리둘레(r=0.683/남, r=0.604/여), 허리둘레/키 비(r=0.633/남, r=0.595/여) 및 체질량지수(r=0.621/남, r=0.534/여)와 남녀 모두에서 유의한 상관관계가 있었으며, 수축기혈압(r=0.229/남, r=0.232/여), 이완기혈압(r=0.285/남, r=0.254/여), 고밀도콜레스테롤(r=-0.254/남, r=-0.326/여), 중성지방(r=0.475/남, r=0.411/여), 공복혈당(r=0.158/남, r=0.234/여)과 남녀 모두에서 유의한 상관관계가 있었다. 대사증후군 예측을 위한 내장지방두께의 cut-off value는 남자 4.58cm (민감도 89.2%, 특이도 71.2%), 여자 3.50cm (민감도 61.2%, 특이도 80.8%)이었으며, 내장지방두께가 남자에서 6cm, 여자에서 5cm 이상부터 대사중후군 위험성이 급격히 증가하였다. 결론 : 초음파로 측정된 내장지방두께는 신체계측지표 및 대사증후군 관련인자와 남녀 모두에서 유의한 상관 관계가 있었으며, 대사증후군 예측을 위한 내장지방두께 기준은 남자 4.58cm, 여자 3.50cm 이었다. 초음파로 측정된 내장지방두께는 복부비만의 유의한 지표가 될 수 있을 것으로 생각된다. 다만 임상에서 복부 비만 지표로 활용되기 위해서는 측정방법의 표준화가 이루어져야 할 것으로 사료된다.
