The widespread pursuit of a thin physique may have a detrimental impact on the wellbeing of preadolescents. The influence of body image distortions on the lifestyles, dieting behaviors, and psychological factors was investigated in 631 fifth and sixth grade children in Kyeonggi-do, Korea. Children were classified into three weight groups (underweight, normal, and overweight) and three perception groups (underestimation, normal, and overestimation). Necessary information was obtained by questionnaire, and each subject's weight status was determined by the Rohrer index calculated from the annual measurement records, which were obtained from the school. According to their current weights, 57.4% of children were normal and 32.2% were overweight or obese, 16.6% of the children overestimated their body weight, and 55.2% had an undistorted body image. Overweight children had desirable lifestyles and dietary habits and presented reasonable weight control behaviors. Compared to those without distortion, the overestimated group had greater interest in weight control ($P$ = 0.003) and dissatisfaction with their body weights ($P$ = 0.011), presented unhealthy reasons to lose weight ($P$ = 0.026), and had higher scores for "feeling sad when comparing own body with others" ($P$ = 0.000) and for "easily getting annoyed and tired" ($P$ = 0.037), even though they had similar obesity indices. More subjects from the overestimation group ($P$ = 0.006) chose drama/movies as their favorite TV programs, suggesting a possible role for the media in body image distortion. These findings suggest that body image distortion can lead preadolescents to develop stress about obesity and unhealthy dieting practices, despite similar obesity indices to those without distorted body images. These results emphasize the importance of having an undistorted body image.

Objectives The purpose of this study is to investigate Korean clinical studies on treatment of childhood obesity and to propose for better treatment options for childhood obesity. Methods Based on RISS, KISS, OASIS, KMbase with the keyword 'childhood obesity', 'child obesity', 'obese child', 'overweight child', total of 21 randomized controlled trials (RCTs), 11 single clinical studies, 3 chart reviews and 3 case reports have been found, and were analyzed. Results and Conclusion 1. Some study subjects were classified based on their sex - only men or women in a group or sometimes both. Another way of classify the study subjects were based on their age - preschooler, primary school students, middle school students, and high school students. The diagnostic criteria of the subjects were BMI (body mass index), Body fat percentage, Obesity index, Weight and unknown criteria. 2. The treatments used in 38 studies were exercise alone, education alone, both exercise and education or herbal therapy. The 7 studies that used herbal therapy as part of their study intervention had a study group with herbal intervention only and the other 2 study group with herbal treatment in addition to exercise and education. 3. 9 studies included herb medicines, electroacupuncture, auricular acupuncture, cupping, aroma massage, infrared light, and abdomen pad. Herb medications used in 5 studies included Chegameuiin-tang 2 kinds, Sobieum, Biman-tnag, and I-razin. 4. The methods of assessment used in 38 studies were classified by 7 categories and anthropometry parameters which is the basic methods are used in all studies 5. Almost studies (29 studies in all 38 studies) were using anthropometric parameters results on significantly effectiveness of childhood obesity. 6. More studies are needed to prove true effectives from various treatments, especially herbal therapy for childhood obesity.

Bisphenol A (BPA) is widely used in the production of polycarbonate plastics, epoxy resins, and food and beverage containers. In the present study, we aimed to investigate the relationship between urinary concentrations of BPA and waist circumference in Korean adults. A total of 1,030 Korean adults (mean age, $44.3{\pm}14.6$ years) were enrolled in the study on the integrated exposure to hazardous materials for safety control, conducted by the Ministry of Food and Drug Safety from 2010 to 2012. Abdominal obesity was defined as having a waist circumference of at least 90 cm and 85 cm for men and women, respectively. The participants were divided into 4 groups according to the urinary BPA concentration quartile. Waist circumference was significantly higher among subjects with a urinary BPA concentration in the highest quartile relative to those in the lowest quartile (p = 0.0071). Linear regression analysis revealed a significant positive association between urinary BPA concentrations and body mass index, body fat, after adjusting for potential confounders. Moreover, subjects with urinary BPA concentrations in the fourth quartile were more likely to be obese compared to those with urinary BPA concentrations in the first quartile (odds ratio, 1.938; 95% CI: 1.314~2.857; p for trend = 0.0106). These findings provide evidence for a positive association between urinary BPA concentration and waist circumference in Korean adults.

Purpose: The incidence of gallstones after gastrectomy for gastric cancer is higher than in the general population. However, the causes and mechanisms of post-gastrectomy gallstones are unclear. The aim of this study was to evaluate the incidence of gallstone formation and the risk factors for their development after gastrectomy for gastric cancer. Materials and Methods: Of 1,744 gastric cancer patients who underwent gastrectomy at Seoul National University Bundang Hospital between January 2010 and December 2012, 1,284 were included in this study and retrospectively reviewed. Patients' age, sex, body mass index (BMI), tumor location, stage, type of gastrectomy, type of reconstruction, and extent of node dissection were evaluated. Results: The incidence of gallstones after gastrectomy for gastric cancer was significantly higher in men than in women (P=0.019). Exclusion of the duodenum during reconstruction was associated with a significantly higher incidence of gallstones (P=0.003). Overweight and obese patients with BMI ${\geq}23kg/m^2$ had significantly higher incidence of gallstones than those with a lower BMI (P=0.006). Multivariate analysis showed that obesity (hazard ratio, HR=1.614; 95% confidence interval, CI: 1.135~2.296; P=0.008), male sex (HR=1.515, 95% CI: 1.029~2.231, P=0.033), and exclusion of the duodenum (HR=1.648, 95% CI: 1.192~2.280, P=0.003) were significant, independent risk factors for gallstones after gastrectomy. Conclusions: The cumulative incidence of gallstones for 5 years after gastrectomy was 15.3%. Male sex, obesity, and exclusion of the duodenum were risk factors for gallstone formation after gastrectomy. Careful surveillance will be required for these patient groups after gastrectomy.

Objectives: According to preceding studies, many people with mental disability have unbalanced dietary habits or excessive intake of calories. Most of them are overweight or obese due to lack of self-control for food consumption, swallowing with inadequate chewing and physical inactivity. Therefore, this study aimed to assess the nutritional intake, including carotenoid, in mentally disabled people and find out a possible solution for nutritional improvement. Methods: People with intellectual disability (N=28), emotional disability (N=44) participated in this study. The disorder grades were from I to III and ages were between 20 and 65 years. Assessments included anthropometry, daily intake of nutrients, including carotenoid, ROMA III questionnaire for assessing bowel movement. Results: The average BMI of intellectually disabled people and emotionally disabled people was in the range of overweight and obesity respectively ($23.7{\pm}6.3kg/m^2$, $25.8{\pm}4.1kg/m^2$). Overall, the frequencies of vegetable and dairy product intakes were lower in this population. When compared with Recommended Nutrient Intake (RNI) from Dietary Reference Intakes for Koreans 2010, the intakes of vitamin $B_1$, vitamin $B_2$ and calcium were insufficient in both groups. Also, lycopene intakes of carotenoid were low, compared with traditional Korean diet of the non-disabled people from the second year 2008 of the 4th National Health and Nutrition Survey. In addition, emotionally disabled people also had lower intake of cryptoxanthin. Conclusions: The mentally disabled people in this study showed lower intakes of vitamin $B_1$, vitamin $B_2$, calcium and carotenoids. Based on these findings, we recommend that it is important to encourage mentally disabled people to consume sufficient amounts of such nutrients in order to promote nutritional status.

Fascia and fasciocutaneous free flaps (using perforators) are adequate reconstructive options with aesthetic and functional advantages, particularly for reconstruction of variable soft tissue defects of the extremities. Although various donor sites have been used for these concerns including temporoparietal fascia, serratus fascia, scapular fascia, fascial component of lateral arm and posterior calf fascia. The authors used temporoparietal and scapular fascia as a free flap for coverage of soft tissue defects and we compare two flap mainly their histologic studies and clinical applications. In our expierience both fascia provide thin, pliable coverage for exposed bone and tendons and provide good postoperative functional restoration on the recipient area. Histologically temporoparietal fascia flap has more rich blood supply and scapular fascia flap is rich in adipose tissue in their composition. In donor site morbidity, both flaps can bring satisfactory results about the donor sites, but the donor site of the temporoparietal fascia flap sometimes revealed conspicious linear scar and transient alopecia in short-haired patients and the scapular fascia flap has a tendency to be wider and thicker in obese patients. After successful application of the both fascia flap as a free flap in 38 patients (25 temporoparietal fascia, 13 scapular fascia) since 1995 ; authors recommend using the temporoparietal fascia flap for women, who tend to have more fat and longer hair, and the scapular fascia flap for men, who tend to be leand & shorter hair.

The purpose of this study was to investigate the effect of left ventricular diastolic function on exercise capacity in hypertensive patients with obesity compared to the obese group. Adults who visited a general hospital in Gyeonggi-do from 2016 to 2019(man: 308, women: 192) were divided into 4 groups according to hypertension and obesity. In the hypertensive obesity group(IV), the A wave and E/E' wave were significantly higher than the normotensive obesity group(II), and the E' wave was significantly lower(respectively p<0.001). The group IV had significantly lower METS(metabolic equivalents) and exercise duration than the group II(respectively p<0.001). In group IV, E/A ratio was positively correlated with METS(p=0.025) and exercise duration(p=0.026). In contrast, E/E' wave in these groups showed a negative correlation with the exercise duration(p=0.046).

As the elderly population has increased in recent years in Korea chronic degenerative diseases prevalent in the aged have garnered attention in relation to food behavior. In general, dietary intakes of elderly Koreans were inadequate in quality as well as in quantity. Especially, intakes of Ca, vitamin A, and riboflavin along with total energy were insufficient. They tended to consume high carbohydrate and low fat energy rates which may be resulted from long standing vegetable-based flood patterns. Relationships between dietary intakes and indices of cardiovascular diseases revealed that blood pressures and serum lipids patterns tended to be poor in individuals having high abdominal fat accumulations which seemed to be related with dietary consumption of high carbohydrate and insufficient intake of many nutrients. These results suggested that a nutritionally balanced diet including animal sources floods is needed in order to prevent an abdominal obesity and cardiovascular diseases. The bone health status of the Korean elderly appeared poor. It was more serious in women recording a higher prevalence rate of osteopenia and osteoporosis than in men. There were strong associations between dietary factors and bone health status. Bone mineral density was found to be higher with higher intakes of protein energy rate, the total amount of feeds, and many nutrients including Ca and p, indicating that a good quality diet is essential in maintaining healthy bone status in later life. mental health condition of the elderly as measured by cognitive function and the degree of depression was also inadequate and had strong association with dietary consumption. The positive results were obtained in individuals having an adequate dict. Therefore, it could be summarized that the physical as well as mental health in elderly Koreans are highly related with their dietary patterns. Thus, the older adults need te consume nutritionally well balanced diet in sufficient amount, which contains various flood items including significant amounts of animal source floods in a daily diet in order to maintain healthy condition.

BACKGROUND/OBJECTIVES: Korean pine nut oil (PNO) has been reported to suppress appetite by increasing satiety hormone release. However, previous studies have rendered inconsistent results and there is lack of information on whether dietary Korean PNO affects the expression of satiety hormone receptors and hypothalamic neuropeptides. Therefore, our study sought to evaluate the chronic effects of Korean PNO on the long-term regulation of energy balance. MATERIALS/METHODS: Five-week-old male C57BL/6 mice were fed with control diets containing 10% kcal fat from Korean PNO or soybean oil (SBO) (PC or SC) or high-fat diets (HFDs) containing 35% kcal fat from lard and 10% kcal fat from Korean PNO or SBO (PHFD or SHFD) for 12 weeks. The expression of gastrointestinal satiety hormone receptors, hypothalamic neuropeptides, and genes related to intestinal lipid absorption and adipose lipid metabolism was then measured. RESULTS: There was no difference in the daily food intake between PNO- and SBO-fed mice; however, the PC and PHFD groups accumulated 30% and 18% less fat compared to SC and SHFD, respectively. Korean PNO-fed mice exhibited higher messenger RNA (mRNA) expression of Ghsr (ghrelin receptor) and Agrp (agouti-related peptide) (P < 0.05), which are expressed when energy consumption is low to induce appetite as well as the appetitesuppressing neuropeptides Pomc and Cartpt (P = 0.079 and 0.056, respectively). Korean PNO downregulated jejunal Cd36 and epididymal Lpl mRNA expressions, which could suppress intestinal fatty acid absorption and fat storage in white adipose tissue. Consistent with these findings, Korean PNO-fed mice had higher levels of fecal non-esterified fatty acid excretion. Korean PNO also tended to downregulate jejunal Apoa4 and upregulate epididymal Adrb3 mRNA levels, suggesting that PNO may decrease chylomicron synthesis and induce lipolysis. CONCLUSIONS: In summary, Korean PNO attenuated body fat accumulation, and appeared to prevent HFD-induced dysregulation of the hypothalamic appetite-suppressing pathway.

BACKGROUND/OBJECTIVE: We examined the hypoglycemic and anti-hyperlipidemic effect of yeast hydrolysate (YH) enriched with Cyclo-His-Pro (CHP) in the C57BL/6J ob/ob mouse model. MATERIALS/METHODS: Mice were separated into 4 groups (8 mice/group) on the basis of blood glucose and body weight: WT control, lean mice given vehicle; ob/ob control, ob/ob mice given vehicle; YH-1, ob/ob mice given 0.5 g/kg of YH; YH-2, ob/ob mice given 1 g/kg of YH. YH in saline or vehicle was administered orally in the same volume every day for 3 weeks. RESULTS: Mice treated with YH (0.5 and 1 g/kg) for 3 weeks displayed a significant reduction in overall body weight gain and perirenal and epididymal adipose tissue weight compared to the ob/ob control group. Additionally, high-density lipoprotein (HDL) cholesterol, glucose, and atherogenic indexes were significantly decreased in the blood of YH-1 and YH-2 groups compared to the ob/ob control. In ob/ob mice, YH administration significantly improved glucose tolerance and blood insulin levels. These data indicate that YH treatment produces potent hypoglycemic and anti-hyperlipidemic effects by controlling body weight, fat mass, blood lipid, insulin levels, and glucose tolerance. CONCLUSION: YH could potentially be used as a treatment option for diabetes and hyperlipidemia. The CHP-enriched YH may be a promising strategy in the development of hypoglycemic peptide nutraceuticals.
