By this study we seek the expectable range of waist circumference (WC) for every degree of body mass index (BMI), which will serve to studies targeting ascertaining the health risk. We studied 2,932 patients (39.6% men and 60.4% women, between 18 and 96 years ) of the same ethnic group who consecutively attended outpatient departments of our clinics between 2000 and 2004. BMI correlated linearl...
BACKGROUND School-based screening and prevention programs for adiposity generally target school children in grades 4 and 6 (age 9-11 years). The aims of this study were to evaluate the validity of body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) in identifying abdominal adiposity in fifth-grade Japanese school children and to determine optimal cut-off values for...
BACKGROUND Currently, obesity has become a worldwide health problem and yet little is known about the impact of changes in obesity indicator on incident hypertension. The aim of this study was to compare the impact of changes in the WC and BMI on incident hypertension in a cohort population. METHODS After a baseline investigation, we conducted the first and the second follow-up assessments fo...
OBJECTIVE To evaluate the sensitivity and specificity of body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) measurements in diagnosing abdominal visceral obesity. METHODS BMI, WC, and WHR were assessed in 690 Chinese adults (305 men and 385 women) and compared with magnetic resonance imaging (MRI) measurements of abdominal visceral adipose tissue (VA). Receiver opera...
We formally evaluated waist circumference (WC) percentile cutoffs for predicting insulin resistance (IR) and whether different cutoffs should be used for adolescents of different race/ethnicities. Analysis was performed for 1575 adolescents aged 12-18 yr from the National Health and Nutrition Examination Survey 1999-2002. Adolescents were classified as having IR if they had a homeostasis model ...
BACKGROUND Waist circumference (WC) is now accepted as a practical measure of adipose tissue distribution. Four body sites for WC measurements are commonly used, as follows: immediately below the lowest ribs (WC1), the narrowest waist (WC2), the midpoint between the lowest rib and the iliac crest (WC3), and immediately above the iliac crest (WC4). OBJECTIVE We sought to compare the magnitude ...
سابقه و هدف: افزایش آب بافت مغز رابطه مستقیم با شدت ادم مغزی دارد و تعیین حجم آب موجود WC یا (Water Content) بافت مغزی بسیار حائز اهمیت است. با توجه به این که تغییرات WC همراه با تغییرات SG یا (Specific Gravity) بافت می شود، این تحقیق به منظور تعیین SG دو نیمکره که در حالت عادی و ادم و به منظور ارتباط آن با آب بافت مغز در رت انجام گرفت. مواد و روش ها: پس از ایجاد موقعیت با استفاده از روش شناسی ...
Metal Matrix Composite (MMC) coatings of Tungsten Carbide (WC) and Nickel (Ni) powder were produced using laser cladding process. A crack free good metallurgically bonded WC-Ni coating about 5mm thick from varying both energy density percent mixture Ni WC. In this study, the microstructure characterised optical microscope (OM), scanning electron (SEM) with EDS, while mechanical properties studi...
A ccumulating evidence suggests that measures of abdominal obesity outperform BMI in predicting diabetes and cardiovascular risk (1–3). However, it is debated which measure of obesity should be used. Currently, waist circumference (WC) is most commonly used and codefines the metabolic syndrome (4). Unlike waist-to-height ratio (WHtR), WC does not take differences in height into account. We hypo...
در این تحقیق ریز ساختار و خواص مکانیکی جوشهای اصطکاکی ti6al4v/(wc-co) مورد بررسی قرار گرفته است. ریزساختار منطقه مجاور جوش در نمونه تیتانیمی در کلیه حالتها متشکل از فریت سوزنی و هم محور همراه با فاز بتا بوده و در کلیه نمونه ها مخلوط شدن مکانیکی و نفوذ متقابل عناصر در یکدیگر رخ داده است. استحکام شکست جوشهای اصطکاکی ti6al4v/(wc-co) با افزایش درصد کبالت موجود در زمینه کاربید تنگستن- کبالت به طور ب...
