This study aims to develop a detailed sizing system for lower body clothing for elderly obese women, using data from the 8th Korean Anthropometric Survey. The research targets 296 elderly women aged 60 to 85, selected from 805 participants in total, who meet the following criteria: Rohrer Index of 1.6 or above, Body Mass Index of 25 or higher, and Waist-Hip Ratio of 0.85 or greater. Elderly women with abdominal obesity exhibit shorter lower body proportions and greater fat accumulation in the torso, around the chest and waist. The findings show that women in their 60s have the highest level of obesity, while waist width and thickness are greatest in women in their 70s, suggesting that abdominal obesity increases with age. According to the KS standards, the main measurement categories were divided into 5cm increments for height, while waist and hip girth were categorized into 5cm and 3cm, respectively, to analyze the distribution of sections. Clothing size standards for lower garments that require a precise fit, such as skirts and formal pants, are presented in 13 sizes, corresponding to a waist girth range of 85–100cm and a hip girth range of 88–97cm. Detailed measurements are categorized into primary and reference areas. Additionally, sizes were presented differently based on whether a precise fit was necessary. For items that did not require a precise fit, ranges were indicated with letters, or ranges were indicated with measurements. Detailed sizes were categorized into primary and reference areas.
Considering the various health problems associated with obesity in dogs, including renal diseases, joint disorders, and skin diseases, effective management strategies and guidelines are urgently needed. This situation has led to a growing demand for veterinary medications aimed at addressing obesity in dogs. However, the field faces a significant hurdle due to the absence of standardized guidelines for assessing the effectiveness of these anti-obesity medications in dogs. In response to this gap, the Animal and Plant Quarantine Agency (APQA) in Korea has made a crucial step by introducing clinical trial guidelines to evaluate the efficacy of treatments for canine obesity, specifically aimed at approving veterinary medicinal products. The guidelines outlined the selection criteria for target dogs, highlighting the importance of consistency within the control and treated groups. Treatment efficacy is subsequently evaluated by physical examination, body fat reduction, and biochemical indicators. In addition, the guidelines cover dosage and administration, monitoring after dosing, and statistical analysis. By doing so, this guideline not only highlights the significance of the APQA’s initiative in improving the care of obese dogs but also provides practical insights to enhance the standardization and effectiveness of clinical trials in veterinary medicine.
본 연구는 12주 복합운동 프로그램이 비만 중년 여성의 심혈관계 기능과 심전도 기반의 ST 분 절 및 QRS에 미치는 영향을 알아보기 위하여 중년 여성 24명을 무작위 배정하였다. 결과에 대한 분석은 집단 내 및 기간·집단 간 차이 검증을 실시하였다. 심혈관계 기능에서 심근 산소소비량은 실험군에서 안정 단계와 운동 중 최고 강도 단계에서 유의한 감소가 나타났으며, 안정 시 집단·기간 간 상호작용 역시 나타 났다. 심박수 회복률은 실험군에서 회복기 2분에 유의한 감소가 나타난 반면 대조군에서는 반대로 유의한 증가가 나타났다. 수축기 혈압에서는 실험군이 유의하게 감소한 것으로 나타났으며, 집단·기간 간 상호작용 역시 나타났다. 이완기 혈압은 실험군 대조군 모두 변화가 없었으며, 맥압에서는 회복기 3분 단계에서 실험 군에서만 통계적으로 유의한 감소가 나타났다. 심전도의 경우 QRS 높이는 실험군이 안정 시, 회복기 3분, 6분, 9분에서 대부분 유의한 증가를 나타낸 반면 QRS 기간은 실험군 대조군 모두 유의한 차이가 없었으 며, ST 분절 높이는 실험군에서 안정 시에 유의하게 증가한 것으로 나타났다. 따라서 본 연구의 결과를 종 합해 보면 12주 복합운동 프로그램은 비만 중년여성의 심혈관계 기능과 심전도에서 심실의 수축력 향상과 심근의 허혈을 개선하는데 긍정적인 효과가 있다고 사료된다.
본 연구는 장수풍뎅이(Allomyrina dichotoma) 유충을 가수분해한 후 발생한 가수분해물 시료의 항비만 효능에 관한 결과이다. 먼저 3T3-L1 세포에 대한 시료의 독성을 테스트하였다. 시료 F10, P10, P30은 세포에 62.5ug/ml 처리 시 세포 생존율은 ~87.5% 정도로 나타났으며 F30의 경우 세포가 모두 건강하게 성장하는 것을 알 수 있었다. 다음으로 지질합성 관여 단백질인 SREBP-1과 FAS에 대한 발현 억제 실험을 진행하였다. 시료 F10과 F30을 처리 하였을 때 SREBP-1과 FAS의 발현을 가장 잘 억제한다는 것을 알 수 있었다. 3T3-L1 지방세포 분화 과정을 Oil Red O staining 방법으로 염색 후 관찰을 진행하였다. 컨트롤과 비교하여 시료 F10, F30, P10과 P30을 처리한 지방 세포들은 모두 세포 분화 억제가 관찰되었으며 특히, 시료 F10에서 지방세포 분화 억제가 활발히 발생한다는 것을 알 수 있었다. 위 결과를 종합해 보면, 시료 F10과 F30을 혼합하여 사용한다면 반려동물에 대하여 효과 있는 항비만 사료를 개발할 수 있으리라 판단된다.
This study analyzes the body shapes of lower-body obese female adolescents and proposes a slacks pattern suitable for their body type. Lower-body obesity is a prevalent type of teenage obesity, and our proposals aim to improve consumer satisfaction in ready-to-wear clothes across this demographic. We first observe characteristics of obese lower bodies, noting significantly above-average thigh and hip circumference. These figures indicate a high degree of curvature in obese lower bodies, along with a large drop value. Leveraging this data, we develop a novel slacks pattern using 3D avatars in a virtual simulation system. The formulas for the main areas of the pattern are as follows: front waist girth W/4+0.75cm+0.5cm, back waist girth W/4+0.5cm– 0.5cm, front hip girth H/4+1.25cm–0.5cm, back hip girth H/4+2cm+0.5cm, front crotch extension H/16+0.5cm, back crotch extension H/8+1cm. Results from appearance evaluations show that this pattern minimizes strain rate on the waist and hips, and its average score is significantly higher than that of an alternative pattern that was also evaluated. The minimized strain rate and high average score indicate that our pattern assigns a sufficient amount of space to the appropriate areas. Based on these results, we expect our research to inform slacks pattern development and production for obese consumers of all types.
This study aimed to determine the anti-obesity effect of adding Wolfiporia extensa Ginns (W) to fermented pollack skin products in an obesity-induced animal model. The experimental groups were the normal diet group (C), high-fat diet group (HF), dried pollack skin (H1), fermented pollack skin (H2), and W of 0.1 (F2-WL), 0.3 (F2-WM), and 0.5 (F2), respectively. It was confirmed that adding W to fermented pollack skin reduced blood triglycerides, total cholesterol, and LDL levels, while increasing HDL levels. Wolfiporia extensa Ginns was effective in controlling weight and improving blood lipids in a dose-dependent manner. In histological analysis, findings of fatty liver induced by a high-fat diet were improved by the addition of H2 and W. Size and density of fat globules in the epididymis were decreased. In addition, the concentration of TNF-α was increased in the high-fat diet group, but decreased by the addition of fermented pollack skin and W. In conclusion, adding fermented dried pollack skin and Wolfiporia extensa Ginns was effective for weight control and blood lipid improvement. Thus, the use of by-products in functional foods is expected to have a high value in the future.
This study investigated the anti-obesity effects of Coriandrum sativum L. ethanol extracts in a high fat diet-induced obesity model (DIO). We confirmed the anti-obesity effects by analysing the expression of the related proteins, weight gain, dietary intake, dietary efficiency, blood biochemistry, histological analysis and western blot analysis. After oral administration of Coriandrum sativum L. ethanol extracts at concentrations of 250 and 500 mg/kg, a significant improvement in dietary efficiency, reduction in weight gain, triglycerides, total cholesterol and LDL-cholesterol in blood lipid was observed for 8 weeks. In addition, improvement in blood glucose and metabolism confirmed through glucose tolerance test was observed. Further, the concentration of alanine transaminase (ALT) in blood was significantly decreased, which improved the fatty liver caused by high-fat diet intake as confirmed by liver tissue analysis. This phenomenon was confirmed to decrease the expression of fat accumulation-related PPARγ and FAS protein in the liver tissue. Especially, it is believed that FAS, a liposynthetic enzyme, has a stronger inhibitory effect than PPARγ. Therefore, Coriandrum sativum L. ethanol extract is thought to improve obesity by reducing blood lipids levels, improving glucose metabolism and inhibiting synthesis of the fat that accumulates in the liver in high-fat diet-induced obesity animal models.
This study was conducted to provide basic data on the antioxidant activity, inhibition of adipocyte differentiation and reactive oxygen species (ROS) production of a mixture of Brassica juncea extract (BJE) and fermented black rice fraction (BRF). We investigated the total phenol content, total flavonoid content, antioxidant effects (DPPH radical scavenging, ABTS radical scavenging, reducing power, FRAP and ORAC assay) and anti-obesity activity of the mixture in 3T3-L1 cells. Our results showed that the total phenol and flavonoid content increased with increasing BRF mixture ratio. The antioxidant activity increased as the BRF mixture ratio increased. In addition, BJE and BRF mixtures did not show any cytotoxicity during the 3T3-L1 differentiation period. During adipocyte differentiation, BJE and BRF mixtures significantly inhibited lipid accumulation and ROS production compared to the control group. These results warrant further experiments to develop an anti-obesity functional food using a mixture of BJE and BRF.
본 연구는 고지방식이를 섭취한 난소절제 쥐의 지방조직에서 제니스테인에 의한 지방조직감소 와 항염증에 대한 운동의 영향을 조사하였다. 고지방식이를 섭취한 쥐(C)에 비해 제니스테인 단독처리(G) 와 운동 단독처리(Ex)는 지방조직무게, 지방세포 크기 및 혈청 속 포도당과 유리 지방산 수치를 감소시켰 으며, 이러한 현상은 제니스테인과 운동을 동시처리(G/Ex) 하였을 경우 더 효과적으로 감소하였다. 지방조 직에서 C에 비해 G와 Ex의 지방생성 유전자와 염증성 사이토카인 유전자의 발현은 모두 감소하였고, 특히 이러한 유전자의 감소 현상은 G와 Ex 각각 보다 G/Ex에서 더욱 효과적이었다. 따라서 본 연구는 고지방 식이를 섭취한 난소절제 쥐에서 제니스테인과 운동의 동시처리는 제니스테인 단독처리에 비해 더 효과적 으로 비만과 지방조직 염증을 개선하였으며 이것은 지방생성 유전자를 긍정적으로 조절한 결과임을 밝혔 다. 본 연구는 제니스테인의 항비만과 지방조직 항염증에 대해 운동이 유익한 영향을 미친다는 것을 제안 한다.
본 연구는 함초를 섭취한 동물쥐에서 비만과 혈중 지질의 개선 효과에 대한 실험을 체계적 문헌고찰을 통해 통계적으로 분석하였다. 각각의 개별 연구는 PubMed, Embase, RISS, DBpia, NDSL과 같은 데이터베이스로부터 수집되었다. 통계분석을 통해 효과크기를 측정하기 위해 Review Manager 5.3 프로그램이 이용되었고 총 9개의 연구가 최종적으로 포함되었다. 비만유발 흰쥐에서 함초의 섭취는 몸 무게를 유의적으로 감소시켰다. 그러나, 식이효율, 간지수와 총콜레스테롤에서 통계적 유의성이 없었다. 또한, 효과크기가 중성지방은 감소하고, 고밀도 콜레스테롤은 증가하였다. 이러한 통계적 분석은 함초가 강력한 항비만과 혈중 지질 개선 효과를 가진다는 결과는 보여준다.
The Cheonggukjang used in this study was made with four soybean cultivars grown and harvested at the National Agrobiodiversity Center of the National Academy of Agricultural Sciences: C1 (KLS87248), C2 (Nongrim 51), C3 (GNU- 2007-14613), and C4 (Daewon). The soybeans were inoculated with Bacillus subtilis AFY-2 and fermented for 0, 12, 21, 36, 45, and 60 h in a culture room at 35°C. ABTS and DPPH radical scavenging activities were significantly increased upon fermentation for 12 hours in all samples and maintained or decreased after 21 hour The inhibition of NO production was significantly increased compared to the LPS-treated group, and the C2 sample showed inhibition of NO production at 12 hours of fermentation, and the C3 sample showed inhibition at 21 hours of fermentation. PCA analysis revealed that the ABTS and DPPH radical scavenging activity and NO production inhibitory activity reached peak levels around 12 h fermentation time for all samples. Our results indicate that the optimal fermentation time of the Cheonggukjang sample is 12 hours, confirming the high correlation of all experiments.
This study investigated the potential role of dietary factors associated with obesity and metabolic syndrome (MetS) in Koreans. The scoping review method was used to evaluate the studies that utilized the secondary data sets comprising the Korean National Health and Nutrition Examination Survey (KNHANES) and the Korean Genome and Epidemiology Study (KoGES). Articles published between 2012 and 2022 were identified using RISS, KISS, DBpia, PubMed, and ScienceDirect databases. In all, there were 32 published articles on obesity and 119 on MetS. Obesity research included eight articles on nutrients, 12 on food items/food groups, two on dietary patterns, nine on dietary behavior/eating habits, and one on the dietary index. MetS studies comprised 34 articles on nutrients, 43 on food items/food groups, seven on dietary patterns, 25 on dietary behavior/eating habits, and 10 on the dietary index. Carbohydrates, alcohol, and coffee consumption were the most frequently studied dietary factors for obesity and MetS. The primary areas of study were largely focused on nutrients and food items/food groups. Thus, to overcome the paucity of information on the relationship of dietary patterns and dietary indexes with obesity and MetS, there is a need for further research using the KNHANES and KoGES data sets.
본 연구는 국민건강영양조사 제6기 자료(KNHANES Ⅵ-3)를 이용하여 성별에 따른 비만 관련 위험요인들을 확인 하고자 생리적 건강지표인 혈액검사와 스트레스를 비교분석 하였다. 연구에 사용된 대상자는 국민건강영양조사 전체 인구 중 성인(19세 이상) 이며 정상 체중과 비만에 해당하는 3,343명을 대상으로 자료를 분석하였다. BMI 지수에서 남성이 여성에 비해 유의미하게 높았으며(p<.001), 특히 비만 그룹이 더 많은 것으로 확인되었다. 여성의 경우 스트 레스가 남성에 비해 높아 성별의 차이를 보였으며(p<.001), 생리학적 지표인 혈액검사에서 여성은 혈소판(PLT) 수치 가 높고(p<.001) 남성의 경우 백혈구(WBC) 수치가 유의미하게 높게 나타났다(p<.001). 성별에 따른 비만의 관련 요 인으로는 체형에 대한 주관적 판단(95% CI=0.026~0.045, p<.001), 스트레스(95% CI=0.487~0.925, p=.015), 백혈구 (95% CI=1.232~1.392, p<.001)가 여성에서 중요한 요인으로 관찰되었다. 따라서, 성별에 따라 주관적 체형 인식 및 스트레스와 객관적 생리학적 지표가 체질량지수의 주요 변인임이 확인되었으며, 이는 추후 비만 예방 교육 및 관련 프로그램 개발을 위한 중요한 기초자료가 될 것으로 생각된다.
The increasing prevalence of obesity is associated with various metabolic diseases such as diabetes, posing significant social and economic burdens to the society. While obesity is a complex disease with multiple factors contributing to its pathophysiology, altered glucose and lipid metabolism is evident in obese patients as well as in animal models. Abnormal metabolic regulation often leads to development of insulin resistance, a hallmark of obesity-induced type 2 diabetes. In this review, we provide a brief overview of altered lipid metabolism manifested in the obese state. In addition, two representative animal models, Mus musculus and Drosophila melanogaster, are presented with experimental approaches adopted for generation and utilization of these models. More specifically, Drosophila has been widely used for studying the core physiological phenomena across phyla for decades, mostly due to the ease of handling and sophisticated genetic manipulations with conserved cell signaling pathways of reduced redundancy. Considering a significant degree of homology in Drosophila for human disease-associated genes, it poses as a versatile in vivo platform to study the pathophysiology of various human diseases. With core metabolic pathways governing energy homeostasis generally conserved, Drosophila can be used as a model for studying molecular mechanisms underlying disease phenotypes manifested in obese and diabetic patients. In this review, we discuss representative Drosophila studies that investigated the effects of dysregulated core signaling pathways on metabolic signatures of obese animals.
In this study, soybean pods of 45 soybean landraces (or varieties) were classified as yellow (19 samples), black (23 samples), or black in green (3 samples) based on soybean seed coat color. Total polyphenol and flavonoid contents were measured, and antioxidant, anti-inflammatory, anti-obesity, and estrogen-like activities were assessed. Total polyphenol and flavonoid content ranges were 24.13-108.03 mg GAE/g and 3.31-72.02 mg CE/g, respectively, and were highest in the black group followed by the yellow group and were least in the black in green group, while ABTS and DPPH activities followed the order black in green > black > yellow. Estrogen-like and estrogen receptor-α activity ranges were 29.06-35.58 pg/mL and 7.05-10.13 pg/mL and were followed the order yellow > black > black in green and black in green > yellow > black, respectively. Nitric oxide (NO) inhibitory and UCP-1 activities followed the same order as estrogen receptor-α activities. Our findings suggest that soybean pods are excellent sources of antioxidants and high-quality functional materials.
This study investigates the relationship between vitamin C intake and obesity prevalence among Korean adults. Based on data of the Korean National Health and Nutrition Examination Survey (2016-2017), a total of 1,356 participants were included in this analysis. Increasing the dietary vitamin C intake resulted in a significantly decreased occurrence of BMI obesity prevalence (p for trend=0.0194) and WC obesity prevalence (p for trend=0.0452). Moreover, increasing the dietary vitamin C intake of Korean adults having a high frequency of eating breakfast resulted in significantly decreased BMI obesity prevalence (p for trend=0.0406) and WC obesity prevalence (p for trend=0.0432). Among the Korean adults who ate out frequently, decreased BMI obesity prevalence was determined with increased intakes of dietary vitamin C (p for trend=0.0193) and total vitamin C (food and dietary supplements) (p for trend=0.0429), whereas significant decrease in WC obesity prevalence was observed with increased dietary vitamin C intake (p for trend=0.0484). Our results provide conclusive evidence that consumption of dietary vitamin C is associated with obesity prevalence in Korean adults, according to their habits of eating breakfast and frequency of eating out.
