purpose this study was conducted to investigate risk factors of obesity and its associated health problems in adolescence in taiwan. methods we enrolled 559 adolescent volunteers with equal numbers of females and males in 2008. participants were divided into two groups: obese (body mass index [bmi] ≧95th percentile) and normal-weight adolescents (bmi: 15th ∼ 85th percentile). each of them compl...

BACKGROUND A high waist-to-hip ratio is associated with unfavorable cardiovascular disease risk factors. This could be due to either a relatively large waist or a small hip girth. OBJECTIVE We sought to define the separate contributions of waist girth, hip girth, and body mass index (BMI) to measures of body composition, fat distribution, and cardiovascular disease risk factors. DESIGN Thre...

BACKGROUND AND OBJECTIVE Different anatomical locations for measuring waist circumference are described in the literature but the best anatomical location for measuring waist circumference in older adults has yet to be established. Thus, an exploratory study was developed to examine which waist circumference best explains abdominal fat mass in older adults. METHODS Waist circumference was mea...

BACKGROUND As a result of both genetic and environmental factors, the body composition and topography of African populations are presumed to be different from western populations. Accordingly, globally accepted anthropometric markers may perform differently in African populations. In the era of rapid emergence of cardio-vascular diseases in sub-Saharan Africa, evidence about the performance of ...

We derive an asymptotically accurate formula for the beam waist of ultrashort, tightly focused fundamental linearly polarized, radially polarized, and azimuthally polarized modes in free space. We compute the exact beam waist via numerical cubature to ascertain the accuracy with which our formula approximates the exact beam waist over a broad range of parameters of practical interest. Based on ...

Body fat (BF) and cardiorespiratory fitness (CRF) are important health markers that ought to be considered in screening exams. The aim of this study was assess the value six indicators, i.e., tri-ponderal mass index (TMI), relative (RFM), waist–BMI ratio, waist-to-height ratio (WHtR), waist-to-hip (WHR) body (BMI) predicting CRF school-aged children. analysis based on data coming from examinati...

This study aimed to evaluate sleep quality and sleepiness level their relationship with obesity indicators in Brazilian military pilots. Forty pilots answered validated questionnaires assess daytime anamnesis. Body mass, height, waist hip circumferences, body composition were measured, waist-to-height ratio (WHTR), waist/hip (WHR), mass index (BMI) calculated. Visceral adipose tissue was measur...
