To study the correlation between body composition values and practice of the Standard Guideline for Korean Dietary Life, a nationwide cross-sectional survey was conducted with 378 female college students living in four Korean cities in December 2005. Among the student subjects, 98 were analyzed for body fat mass, percent body fat, waist-hip ratio(WHR), body mass index(BMI) and obesity degree using Inbody 3.0(Biospace Co, Seoul, Korea). Percent body fat was at a high level of 54.1 %, WHR was at a high level of 58.2% and BMI was at a high level of 41.8%. However, both weight and body fat were below normal at 79.5% and 77.6%, respectively. Percent body fat, WHR, and BMI were slightly negatively correlated with vegetable consumption, but slightly positively correlated with beer intake. WHR > 0.8 was significantly negatively correlated with exercise. Standard Guideline for Korean Dietary Life was practiced to and above normal level by 64.6% of the female college students. However, female college students who are within the normal range of body composition value should notice that obesity will relate to abdominal or visceral fat on their body.

Background: Fat stranding is a non-specific finding of an increased fat attenuation on computed tomography (CT) images. Fat stranding is used for detecting the underlying lesion in humans. Objectives: To assess the clinical significance of fat stranding on CT images for identifying the underlying cause in dogs and cats. Methods: In this retrospective study, the incidence, location, extent, distribution, and pattern of fat stranding were assessed on CT studies obtained from 134 cases. Results: Fat stranding was found in 38% (51/134) of all cases and in 35% (37/107) of tumors, which was significantly higher in malignant tumors (44%) than benign tumors (12%). Moreover, fat stranding was found in more than two areas in malignant tumors (16/33) and in a single area in benign tumors (4/4). In inflammation, fat stranding was demonstrated in 54% (7/13) in a single area (7/7) as a focal distribution (6/7). In trauma, fat stranding was revealed in 50% (7/14) and most were in multiple areas (6/7). Regardless of the etiologies, fat stranding was always around the underlying lesion and a reticular pattern was the most common presentation. Logistic regression analysis revealed that multiple areas (p = 0.040) of fat stranding and a reticulonodular pattern (p = 0.022) are the significant predictors of malignant tumor. Conclusions: These findings indicated that CT fat stranding can be used as a clue for identifying the underlying lesion and can be useful for narrowing the differential list based on the extent and pattern.

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.

Objectives In this study, it was investigated whether Gami-Handayeolso-Tang (HDYST) medication has anti-obesity effects in high fat diet (HFD)-fed obese mice. Methods The experimental animals were divided into five groups-normal diet-fed (ND), high fat diet-fed control (HFD), HFD+HDYST 150, HFD+HDYST 300, and HFD+orlistat as a positive drug. The obese markers such as body weight, diet efficiency ratio, serum levels of total cholesterol, triglyceride, lipid contents, leptin, adiponectin, and GOT/GPT were measured. Also, white adipose tissue, liver weight, abdominal fat mass, hepatic lipid contents, and mRNA expression of obese-associating genes were examined in obese mice. Results In high fat diet-fed mice, HDYST administration significantly decreased body weight, diet efficiency ratio, serum levels of total cholesterol, triglyceride, LDL-cholesterol, as well as leptin and GOT/GPT, compared to the HFD group in a dose-dependent manner. HDYST increased significantly the serum levels of HDL-cholesterol and adiponectin. It also reduced the accumulation of lipids, such as total lipid and triglycerides, in organs such as liver and abdominal adipose tissue. Moreover, HDYST administration significantly decreased the expression levels of fatty acid synthetic genes, such as sterol regulatory element-binding protein-1c (SREBP-1c), FAS and Stearoyl-Coenzyme A desaturase 1 (SCD-1), in the liver tissues, while it increased the messenger RAN (mRNA) levels of fatty acid catalytic genes, such as Peroxisome proliferator activated receptor alpha (PPAR-${\alpha}$), acyl-COA oxidase (ACO), and Carnitine palmitoyltransferase-1a (CPT-1a). Conclusions Based on the results above, HDYST reveals anti-obesity effects declining body fat accumulation through the regulation of fatty acid metabolism and leptin/adiponectin serum levels. It therefore suggests that HDYST can be clinically useful for the treatment of obesity.

Abdominal obesity is increasing due to a decrease in physical activity and westernization of diet in busy daily life. Therefore, in order to satisfy the desire for body shape management, a management program with high efficiency versus time is needed. In this study, the diet-gel (i.e., slimming cosmetics) with the electrical muscle stimulation therapy was used to promote the effect of reducing waist circumference and body fat mass (or abdominal fat). For men and women in their twenties, the subjects simply applied diet-gel to their waist, wore EMS, and massaged for 20 minutes twice a day after waking up and before going to sleep. The experiment period was carried out for 2 weeks. The reduction of subcutaneous fat was observed using non-contrast CT, and it was confirmed by measuring waist circumference and body fat mass. In conclusion, the developed EMS and diet-gel combination program showed excellent waist management effects by reducing waist circumference by about 3 cm (p<0.001) and body fat mass by about 1 kg (p<0.01). This result suggests that the use of EMS shows a massage effect by muscle stimulation, and plays a role in promoting fat decomposition by helping the absorption of diet gel.

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.

A 21- to 42-day feeding study was conducted in Ross male broilers to evaluate the use of dried bakery product (DBP) and the influence of adding fat at different points in the manufacturing process. Six dietary treatments were formulated using a factorial arrangement (3${\times}$2 design) with three levels of fat in the mixer (high: 4.8%, medium: 3.8% and low: 2.8%) with or without DBP (0 and 7%). Additional fat was sprayed on pellets in a post-pelleting liquid application to bring the fat content to a similar level in all diets. Data on pellet quality (before and after post-pelleting fat addition), broiler performance, nutrient digestibility and organ weights were studied. Pellets made with DBP showed higher hardness values when measured before post-pelleting fat addition (p<0.001), although DBP did not affect final pellet hardness or durability. Higher post-pelleting hardness and durability were shown by diets to which a lower level of fat had been added in the mixer (p<0.001). In general, post-pelleting fat application improved durability (p<0.05). However, broiler performance and ileal digestibility were not affected by any of the factors tested. Dietary treatments had a significant but variable effect on carcass yield (p<0.01), although there were no differences among treatments regarding breast and leg yield, abdominal fat or organ weights. The results indicate that up to 7% DBP could be used in the broiler diet without impairing performance, ileal digestibility or organ weights. The place or point of fat addition in the manufacturing process has a strong influence on pellet quality.

This study was performed to examine the relationship between the body mass index (BMI), the body fat, and the serum lipids of post-menopausal women in rural areas. The subjects were 510 women aged 50 and over. As a result of this study, we found a trend of decreasing BMI as age increased, but body fat increased. In addition, there was a significant decreasing of the lean body mass than an increasing of the body mass index according to increasing age. Therefore, this study confirmed that a main cause of rural women being classified as obese is a decrease in lean body mass, rather than an increase in of body fat. Of all subjects, 36.3% ($18.5{\leq}BMI$ < 23) of all subjects were classified as having normal BMI, whereas only 21.4% were classified as having normal body fat. Out of 190 subjects who were body fat 30% and over, 38 subjects were classified as obese ($BMI{\geq}25$) and 113 subjects were classified as overweight ($23{\leq}BMI$ < 25). The percentile of those with a BMI of $25kg/m^2$ was 70, and they had 30.82% body fat. HDL cholesterol showed a negative correlation with anthropometric factors (height, weight, body mass index, waist circumference, waist hip ratio, body fat), and total cholesterol, LDL cholesterol, and triglycerides showed a positive correlation. Especially, total cholesterol, LDL cholesterol, and hip circumference showed significant correlations. Because of differences in the body fat and lean body mass by age group, it seems difficult to assess obesity via BMI only. The elderly especially should have a higher significance placed on body fat or abdominal fat than only BMI.

An extract obtained from germinated brown rice was evaluated for protective effects against the adverse effects of a chronic high fat diet. C57BL6/J mice were divided into three groups; normal diet + water group (ND), high fat diet + water group (HD), high fat diet + brown rice water extract group (HD + BE) and fed for 8 weeks (6 day/week). The ND group diet was 11 kcal fat $\%$. The HD group and HD + BE group diet were 42 kcal fat $\%$. Weight gains were not significantly different between groups. However, abdominal fat $\%$ was 1.6-fold higher in the HD group than HD + BE group. Feed consumption was significantly higher in the ND group than HD group. Serum triglyceride, total cholesterol and LDL-cholesterol increased with a high fat diet, but decreased by brown rice water extract administration to the high fat diet group. Serum HDL-cholesterol decreased by the high fat diet, but increased by the brown rice wate extract administration. Also, serum HDL-cholesterol/total cholesterol ratio was 2.3-fold higher in the HD + BE than the HD. Liver triglyceride and total cholesterol were not significantly different among groups. These data suggest that brown rice water extract administration improves the serum lipid profiles of C57BL/6J mice.

BACKGROUNDS/OBJECTIVES: Cancer treatment may lead to significant body composition changes and affect growth and disease outcomes in pediatric cancer patients. This prospective study aimed to evaluate short- and long-term body compositions changes focused on body fat during the first year of cancer treatment in children. SUBJECTS/METHODS: A prospective study was conducted in 30 pediatric cancer patients (19 hematologic malignancies and 11 solid tumors) and 30 age- and sex-matched healthy controls. Anthropometric measurements and body composition analysis using whole body dual energy X-ray absorptiometry were performed at baseline and 1, 6, and 12 month(s) of cancer treatment. Kruskal-Wallis tests, Wilcoxon paired t tests, and generalized estimation equation (GEE) were applied for statistical analysis. RESULTS: At baseline, no differences in weight, height, body mass index, abdominal circumferences, body fat, and fat-free mass were observed between 30 controls and 30 pediatric cancer patients. Total fat mass (P < 0.001) and body fat percentage (P = 0.002) increased significantly during the first month, but no changes were observed from 1 to 12 months; however, no changes in the total mass were observed during the first year of cancer treatment. Meanwhile, the total fat-free mass decreased during the first month (P = 0.008) and recovered between 6 and 12 months of follow-up (P < 0.001). According to GEE analysis, there was a significant upward trend in body fat percentage during the first year, especially the first month, of cancer treatment in children with hematologic malignancies, but not in those with solid tumors. CONCLUSIONS: Our results indicate that cancer treatment is related to significant body composition changes and rapid body fat gain, particularly during the first month after initiating cancer treatment, in children with hematologic malignancies. Therefore, individualized dietary strategies to prevent excessive fat gain are needed in pediatric cancer patients for better outcomes.
