BACKGROUND The prevalence of childhood obesity has risen greatly worldwide. However, assessment of obesity among children and adolescents is further complicated by the changes occurring in the body composition during the growth. The aim of this study is to create gender-specific percentile curves for total body fat percentage (TBFP), total body fat mass (TBFM), fat mass index (FMI), and fat fre...

BACKGROUND AND OBJECTIVES New US Down syndrome (DS) BMI growth charts were recently published, but their utility in identifying children with excess adiposity or increased cardiometabolic risk (CMR) remains unknown. We sought to compare the ability of the Centers for Disease Control and Prevention (CDC) BMI 85th percentile and DS-specific BMI 85th percentile to identify excess adiposity in chil...

OBJECTIVE To examine whether physical activity (PA) and sedentary time (ST) in primary school-aged children are associated with adiposity at the start of secondary school, and whether these associations differ by sex or ethnic group. DESIGN Nationally representative prospective cohort study. SETTING Children born across the UK, between 2000 and 2002. PARTICIPANTS 6497 singleton children. ...

PURPOSE The aims of the study were to develop sex- and age-specific percentiles for lean mass index (LMI), appendicular LMI (aLMI), fat mass index (FMI), and body fat distribution indices in Chinese adults using dual-energy X-ray absorptiometry (DXA), and to compare those indices with those of other ethnicities using the US NHANES data. METHODS Whole-body and regional lean mass and fat mass (...

BACKGROUND We longitudinally assessed predictors of insulin resistance (IR) change among HIV-uninfected and HIV-infected (ART-initiators and ART-non-initiators) Rwandan women. METHODOLOGY HIV-infected (HIV+) and uninfected (HIV-) women provided demographic and clinical measures: age, body mass index (BMI) in Kg/(height in meters)2, Fat-Mass (FMI) and Fat-Free-Mass (FFMI) index, fasting serum ...

AIMS Body mass index (BMI) shows several limitations as indicator of fatness. Using the International Obesity Task Force (IOTF) reference and the World Health Organization (WHO) standard 2007 on the same dataset yielded widely different rates. At higher levels, BMI and the BMI cut-offs may be help in informing a clinical judgement, but at levels near the norm additional criteria may be needed. ...

With the current trend towards multi-core processors and computer grids, parallelism in system simulation is becoming inevitable. Performing multiple tasks concurrently can save both time and money. However, this also puts higher demands on simulation software. This thesis investigates how simulation-based product development can benefit from distributed simulation. One parallelization method i...

Server transaction logs containing complete click-through data from a digital library of primarily image-based documents were analyzed to better understand user search session behavior. One month of data was analyzed using descriptive statistics and network analysis methods. The findings reveal iterative search behaviors centered on result views and evaluation and topical areas of focus for the...

This paper analyses computed tomography (CT) images of hardwood logs, with the goal of locating internal defects. The ability to detect and identify defects automatically is a critical component of efficiency improvements for future sawmills and veneer mills. This paper describes an approach in which 1) histogram equalization is used during preprocessing to normalize pixel values; 2) a feedforw...
