Purpose: Visceral adipose tissue may be strongly linked to increased metabolic risks in adults. However, because little is known regarding the effect of visceral adipose tissue in children and adolescents, we performed this study to determine the association between abdominal fat distribution and metabolic risk factors in this population. Methods: One hundred one children and adolescents (78 males and 23 females; mean age, 10.8${\pm}$2.4 years) were enrolled. The anthropometric data and metabolic risk factors were evaluated. Theabdominal fat distribution was assessed according to the CT measurement. Age-adjusted, partial correlations were performed among the visceral adipose fat area (VFA), subcutaneous adiposefat area (SFA), metabolic risk factors, and anthropometrics. Results: The SFA increased more rapidly than the VFA with advancing years in both genders. In males, the VFA and SFA were positively correlated with anthropometrics. The VFA was correlated with low HDL-cholesterol and the SFA was correlated with diastolic blood pressure (DBP). However, there was no statistical significance between the VFA, SFA, anthropometrics, and other metabolic risk factors. The VFA and SFA were strongly linked to a number of metabolic risk factors, such as other anthropometrics. Conclusion: This study investigated how a low HDL-C was correlated with VFA and how a high DBP was associated with SFA in Korean male children and adolescents. Our results suggest that the correlation between the VFA, SFA, and metabolic risk factors was relatively weak compared to that reported in previous adult studies.

To figure out the causes of obesity against middle-aged women, this study aimed to provide basic data for setting an obesity-related policy through analysis on diverse related factors. Against the healthy middle-aged women who visited 'N' Hospital Health Center in Incheon from April to November 2014, anthropometric assessment, body composition test and abdominal fat distribution test were conducted using Fat-CT. They were carried out against 159 women who agreed with the purpose of the study, using BMD, Q-CT. According to Fat-CT, subcutaneous and visceral types accounted for 39% (76 women) and 61% (119 respondents) respectively. In terms of BMI, 'underweight ($18.5kg/m^2$)' and 'overweight ($25kg/m^2$ or above)' were 13 women (6.7%) and 60 women (30.8%) each with the average of $23.5{\pm}4.11kg/m^2$. Mean while, waist circumference, diastolic blood pressure, systolic blood pressure and neutral fat were statistically significant at the 5% significance level. As getting older, muscle weakness offsets increase in body weight with abdominal obesity. A group with low BMI should also be considered due to increase in waist circumference.

The purpose of this study was to analyze the relationship between hematologic hyperlipemia index and severity of fatty liver abdominal ultrasonography. A total of 412 adults from January 1, 2017 to December 31, 2017 who underwent abdominal ultrasonography and hematologic data within 3 months of the ultrasound examination, were the target of the investigation. As a result of the study, the hematological values according to the degree of fatty liver were statistically significant in triglyceride, AST and ALT (p<.05), fatty liver was associated with gender, triglyceride, AST and ALT (p<.05). In conclusion, the degree of fatty liver was not directly related to the hematologic value of hyperlipidemia, but we confirmed the necessity of co-management with fatty liver and hyperlipidemia by confirming its relevance.

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.

The study aimed to compare the validity between the abdominal ultrasonographic(US) grading system of fatty liver and histologic grading system of fatty liver in living liver donor candidates. As the fatty liver is defined as pathologic total fat >10%, US validity was sensitivity 64.6%, specificity 68%, positive predictive value 76.8%, negative predictive value 54%. As the strict data handling on US grading normal, mild fatty liver are negative, moderate fatty liver is positive, US validity was sensitivity 26.8%, specificity 100%, positive predictive value 100%, negative predictive value 45.5%. ROC curve analysis according to different cut off value of liver-to-kidney brightness ratio was Area under ROC curve=0.859(95% CI=0.795~0.922, state variable= total fat 10%). There were statistically significant difference( p<0.001). Ultrasonography for the fatty diagnosis showed a high validity to predict the result of histology grade of fatty liver.

We investigated the serum cholesterol and visceral fat lowering effects of Momordica charanatia (MC) and Withania somnifera (WS) extracts in high-fat diet (HFD)-fed mice. Combination of fermented MC and WS extracts (FMCWS) as well as that of non-fermented extracts (MCWS) were orally administered to HFD-induced obese mice along with the HFD supplementation for 8 weeks. During the experiment, body weight, food intake, and levels of total cholesterol, triglyceride and HDL-cholesterol were analyzed. Body weight and the levels of total cholesterol and triglycerides were significantly increased in the HFD-fed mice compared with the normal control (NC) group. However, supplementation of the extracts showed a tendency to reduce body weight gain and suppressed the levels of total cholesterol and triglyceride with the increment of HDL-cholesterol levels. Abdominal fat weight was significantly increased in the HFD group, and the size of adipocytes within the epididymal adipose tissue was markedly expanded compared with the NC group. However, in the FMCWS and MCWS groups, the abdominal fat weight was significantly reduced and the sizes of the adipocytes were noticeably diminished compared with those of the HFD-fed mice. Moreover, the deposition of giant vesicular fat cells observed in the liver tissue of the HFD group was prominently reduced in these groups. These results indicate that the combination of extracts from MC and WS tends to have potent synergic effects in reducing body weight gain as well as significantly lowering the visceral fat and the serum lipid levels, and thus improving anti-obesity efficacy in HFD-induced obese mice.

This study retrospectively analyzed the test results of 441 patients who visited Hospital I in Busan from October 2021 to December 2021 and conducted both mid-term ultrasound and fibroscan tests. The purpose of the study was to investigate the usefulness of fibroscan in inter-fat evaluation by conducting correlation analysis and chi-squared test of inter-fat evaluation using liver ultrasound and fibroscan. As a result of analyzing the correlation between the fatty liver reading result of abdominal ultrasound and Fibroscan UAP, the correlation was found to be r=0.600 and p=0.000. In the inter-provincial evaluation, Fibroscan showed high validity in predicting objective results using inter-provincial values.

본 논문에서는 복부의 전산화 단층촬영 영상으로부터 체지방의 양을 측정하기 위한 영상처리에서 사용되는 문턱치의 자동 설정 방법을 제안한다. 체지방의 정량적 측정은 비만과 관련된 진단 및 치료에 있어서 중요하다. 기존의 비만도 측정은 체중과 신장의 비, 허리와 둔부 둘레의 비, 손으로 잡히는 복부의 두께 등 단순한 측정방법을 사용하여 실제 지방의 양을 제대로 반영하지 못하는 단점이 있다. 이러한 단점을 보완하기 위하여 최근에 전산화 단층촬영 영상으로부터 영상처리를 통하여 직접 지방의 양을 측정하려는 시도가 있다. 전산화 단층촬영 영상을 이용하면 지방의 양을 정량적으로 측정할 수 있고 피하지방과 복강내지방 등 특정부위의 체지방의 양을 측정할 수 있다. 전산화 단층촬영은 밀도에 비례하는 하운스필드 단위 값으로 구성된 영상을 제공한다. 일반적으로 체지방은 하운스필드 단위 값이 -150에서 -50사이인 것으로 알려져 있다. 그러나, 체지방의 문턱치는 사람에 따라 다르고, 또한 같은 사람에 대해서도 촬영 부위에 따라 다르다. 본 논문에서는 이러한 차이를 히스토그램을 통하여 보이고 히스토그램의 가우시안 함수 근사로부터 체지방의 문턱치를 자동으로 설정하는 방법을 제안한다.

본 연구는 안전하면서 효율적으로 비만을 개선시키는데 도움이 될 수 있는 식품소재로 목이버섯을 선정하여 복부 비만이 있는 중년 여성의 골밀도 및 혈청지질농도에 미치는 영향에 대하여 알아보고자 하였다. 30~50대의 복부비만 여성 30명에게 4주 동안 대조군은 목이버섯을 섭취시키지 않았고, 실험군은 목이버섯을 식사와 함께 섭취하도록 하였다. 실험 전 후 골밀도(T-score, Z-score), 총 콜레스테롤, HDL-콜레스테롤, LDL-콜레스테롤, 중성지방을 측정하였다. 연구결과, 목이버섯 섭취군과 대조군 간에 T-score와 Z-score는 유의한 차이를 보이지 않았지만, 목이버섯 섭취군의 혈청 총 콜레스테롤, LDL-콜레스테롤 및 중성지방 수준이 대조군에 비해 유의하게 감소되었다.
